GIS to CIM Data Translation Template Reference GuideContentsIntroduction (3)What is the CIM? (3)How a CIM Translation Template Can Help (4)How the Sample Template Works (5)Approach A: Walk-through for Setting up using a Spatial ETL Tool with the ArcGIS Data Interoperability Extension (5)Approach B: Walk-through for Setting up using FME (12)Resources (16)© Esri 2013IntroductionThe purpose of this document is to provide information about a sample Common Information Model (CIM) XML data translation template which Esri has developed with Safe Software in order to provide a basic approach to translating data from an Esri geodatabase to the CIM XML format, where it can potentially then be shared between other enterprise systems.Information provided will include a brief overview of CIM, an introduction to the data translation template and how it can be used within a GIS enterprise scenario, and a basic walk-through to guide a user through a simple test of its use.What is the CIM?CIM stands for the “Common Information Model” which for the electric power transmission and distribution industry, represents a set of open standards developed by the Electric Power Research Institute (EPRI) and the electric power industry, and which has been officially adopted by the International Electrotechnical Commission (IEC). One of t he CIM’s key objectives is to provide a way for application software to exchange information about the configuration and status of an electrical network.The CIM is maintained as a Unified Modeling Language (UML) model, and defines a common set of electric data objects. Through the use of UML software such as Sparx Systems’ Enterprise Architect, the CIM UML can be used to create design artifacts, such as XML / RDF schema which can then be used as a template for the exchange of data between integrated software applications and systems.There are a number of IEC standards related to CIM, including:∙IEC 61970-301: Defines a core set of packages for the CIM, with focus on the needs of electricity transmission, where related applications include energy management system, SCADA, planning and optimization.∙IEC 61970-501 and 61970-452: Define an XML format for network model exchanges using RDF.∙IEC 61968: Defines a series of standards to extend the CIM to meet the needs of electrical distribution, where related applications include distribution managementsystem, outage management system, planning, metering, work management, geographic information system, asset management, customer information systems and enterpriseresource planning.From the perspective of users of GIS (geographic information systems), the CIM provides a useful data exchange schema for electrical objects, and is of primary importance for electric utilities who have an enterprise GIS system which needs to interface with other applications / systems as part of their overall enterprise implementation, and also potentially those who may need to share their electrical network data between companies / agencies.Enterprise GIS capabilities provide broad access to geospatial data and applications throughout the organization. The advantages to deploying an enterprise GIS include:∙Using a common infrastructure for building and deploying GIS solutions∙Extending geospatial capabilities to an enterprise community∙Improving capabilities of other enterprise systems by leveraging the value of geographic information∙Increasing overall operating efficiency using GIS across your organizationGeospatial information can also be integrated with other enterprise applications to enable distribution analysis and support key decision-support systems. The CIM model as a mechanism for enterprise system integration, can be of use in this process. Some key areas of data exchange would occur between GIS, DMS, SCADA, OMS, CIS, WMS and AMI.How a CIM Translation Template Can HelpThe CIM is extensive and complex, and the CIM RDF XML structure can likewise be very challenging to navigate. There are CIM standards websites online with different types of resources, and there can be a fairly significant learning curve associated with the materials. EPRI provides some very good resources such as their CIM Primer which walks through some of the main aspects which will be of concern for GIS users such as navigating CIM UML and the CIM RDF XML structure, generating XML schema, messaging and extending the CIM. Some resource links are found at the end of this document.Given the complexities around CIM, Esri has worked with Safe Software to develop a proof of concept template for demonstrating the process of migrating GIS data to the CIM RDF XML structure. The demonstration is intended to provide users the ability to see how CIM XML for enterprise system integration purposes can be created. The CIM translation template process which this document will outline is just one way of performing translation to CIM XML. As using both the ArcGIS Data Interoperability extension and Safe’s FME product are popular ways to move spatial data in and out of a geodatabase, it was identified as a good starting point for Esri GIS users to begin a review of CIM and some of the data translation considerations around it. The CIM translation template consists of both an FME workspace and a Data Interoperability ETL (Extract, Transform, Load) tool, along with a sample dataset which has been referenced in the configuration so that the user can quickly test how the translation process works. The user can also further review the template’s configuration and copy and modify it and/or build a new configuration which references another dataset. The template provides a framework by which the user can begin to envision how their own data can be tailored, configured and translated to the CIM.How the Sample Template WorksIn order to use the template, the user will require the following software:o ArcGIS Desktop 10.1 SP1 (or higher) and the Esri Data Interoperability extension 10.1 SP1 (or higher)Or:o FME (Feature Manipulation Engine) Desktop 2012 SP1 (or higher) from Safe SoftwareAs for the skillset involved, experience with the above software is of course recommended, although a high level of proficiency is not seen as necessary to simply run the template with the accompanying sample data and get the sample template to run and export CIM XML from a test geodatabase.Proficiency will be required in order to perform actual configuration work based on the template, and will require expertise with the Data Workbench component which comes with FME and the Data Interoperability extension. Again, this is needed if the user is looking to customize the workspace template to their own data.As referenced in the Resources section at the end of this document, some basic training is available for the ArcGIS Data Interoperability extensi on through Esri’s Training site, as well as FME through Safe’s FME site.Approach A: Walk-through for Setting up using a Spatial ETL Tool with the ArcGIS Data Interoperability ExtensionThe following are basic steps to follow when using the template with ArcGIS Desktop 10.1 SP1 (or higher) and the Esri Data Interoperability extension 10.1 SP1 (or higher).Extract the Template Zipfile Package:In order to maintain paths as currently defined in documents, files should be extracted to the following folder: C:\temp\GDB_to_CIM_Template\. To do this, place the accompanying zipfile, “GDB_to_CIM_Template.zip”, in the C:\temp directory, and extract it at its location to a folder with the same name as the zipfile. This is usually the default option as seen in the following:Once extracted you will find four items in the C:\temp\GDB_to_CIM_Template\ folder as seen in the following:These four items include:∙Electric_Source_Sample.gdb– A sample file geodatabase containing electric distribution feature classes with features that can be converted to CIM XML with the tools provided in the template. The classes include:o Circuit Breakero Fuseo Meterso Transformerso Primary Overheado Primary Undergroundo Secondary Overhead∙ArcMap Document – CIM Template.mxd– An ArcMap document file containing the features from the above sample file geodatabase and a reference to Spatial ETL tool in a file-based toolbox. Note: This file is used if the user has ArcGIS Desktop and the DataInteroperability extension.∙Data Interoperability – CIM Template.tbx– A file-based toolbox containing a Spatial ETL tool with the CIM Template configuration for data translation of the above sample geodatabase to CIM XML. Note: This file is used if the user has ArcGIS Desktop and the Data Interoperability extension.∙FME Workspace – CIM Template.fmw – An FME Workspace file containing the same ETL configuration as the above toolbox, for data translation of the above sample geodatabaseto CIM XML. Note: This file is used if the user wants to use FME in place of ArcGIS Desktop and the Data Interoperability extension.Launch ArcMap and Load MXD:Once the above files are extracted at the “C:\temp\GDB_to_CIM_Template” folder location, launch ArcMap and open the ArcMap document file named “ArcMap Document – CIM Template.mxd”. This will load the data in the sample file geodatabase, and make the ArcToolbox visible.Add CIM Template Toolbox:In ArcToolbox, add the Spatial ETL toolbox, navigating to the extraction folder as seen in the following:Once added, you will see the following new toolbox available –“Data Interoperability CIM Template” and once expanded you will find the Spatial ETL tool labeled “GDB to CIM XML Template”:Run the ToolAt this point, you can open the tool like any standard geoprocessing tool by double-clicking or right-clicking and selecting “Open”. The following shows the template tool dialog with the default locations set for both the input source file geodatabase and the output CIM XML file, which defaults to the main extraction folder. Press “OK” to accept the defaults.The tool will run for about 1 – 2 minutes depending on your machine and will show the following at the bottom of the ArcToolbox / ArcMap when completed:Review ResultsAfter the tool runs, you can then click on the completion message box above to quickly move to the Results log in ArcToolbox:By scrolling to the bottom, you can see if the tool completed successfully. You should see the following messages if it did:Next, c heck the extraction folder to see if the file “CIMRDFXML--Output CIM XML File.xml” was created as seen here:This default name for the file was configured in the ETL tool. You can now review the content of the XML file which was produced. Open, view or edit the created file in your XML tool of choice to examine the content produced by the tool:Review the Template Tool ConfigurationTo review the ETL tool configuration, right-click the tool in the toolbox and select “Edit”:This brings up the Data Interoperability Workbench:You can now explore the template’s configuration, copy the tool and make modifications as desired based on the sample, or begin working with your own data.This concludes the walk-through of the template based on the ArcGIS Data Interoperability extension.Approach B: Walk-through for Setting up using FMEThe following are basic steps to follow when using the template with FME (Feature Manipulation Engine) 2012 SP1 (or higher). Most of these steps are covered in Approach A for the ArcGIS Data Interoperability extension, although are repeated here so the user has a full procedure for use with FME in one section.Extract the Template Zipfile Package:In order to maintain paths as currently defined in documents, files should be extracted to the following folder: C:\temp\GDB_to_CIM_Template\. To do this, place the accompanying zipfile, “GDB_to_CIM_Template.zip”, in the C:\temp directory, and extract it at its location to a folder with the same name as the zipfile. This is usually the default option as seen in the following:Once extracted you will find four items in the C:\temp\GDB_to_CIM_Template\ folder as seen in the following:These four items include:Electric_Source_Sample.gdb– A sample file geodatabase containing electric distribution feature classes with features that can be converted to CIM XML with the tools provided in the template. The classes include:o Circuit Breakero Fuseo Meterso Transformerso Primary Overheado Primary Undergroundo Secondary Overhead∙ArcMap Document – CIM Template.mxd– An ArcMap document file containing the features from the above sample file geodatabase and a reference to Spatial ETL tool in a file-based toolbox. Note: This file is used if the user has ArcGIS Desktop and the DataInteroperability extension.∙Data Interoperability – CIM Template.tbx– A file-based toolbox containing a Spatial ETL tool with the CIM Template configuration for data translation of the above samplegeodatabase to CIM XML. Note: This file is used if the user has ArcGIS Desktop and the Data Interoperability extension.∙FME Workspace – CIM Template.fmw – An FME Workspace file containing the same ETL configuration as the above toolbox, for data translation of the above sample geodatabase to CIM XML. Note: This file is used if the user wants to use FME in place of ArcGISDesktop and the Data Interoperability extension.Launch FME and Load FME Workspace:Once the above files are extracted at the “C:\temp\GDB_to_CIM_Template” fold er location, launch FME and open the FME Workspace file named “FME Workspace - CIM Template.fmw”. You will then see the FME workbench and the CIM Template configuration:Run the TranslationAt this point, you can run the translation as-is with all of the default values, as long as the files were extracted extracted to the “C:\temp\GDB_to_CIM_Template” folder location. To run the translation, press the first green “Run Translation” button on the FME toolbar:As the translation starts, the log window will appear and provide updates on progress. The tool will run for about 1 – 2 minutes depending on your machine and will show notes on the completion of the translation at the bottom of the log window.Review ResultsAt the bottom of the log window, you will be able to determine if the translation completed successfully and an XML file was written, such as in the following:Next, check the extraction folder to see if the file “CIMRDFXML--Output CIM XML File - FME.xml” was created as seen here:This default name for the file was configured in the ETL tool. You can now review the content of the XML file which was produced. Open, view or edit the created file in your XML tool of choice to examine the content produced by the tool:You can now explore the template’s configuration, make a copy of the FME workspace and make modifications as desired based on the sample, or begin working with your own data. This concludes the walk-through of the CIM template based on FME.Resources∙CIM Links and Documents:o International Electrotechnical Commission (IEC) Smart Grid Standards▪http://www.iec.ch/smartgrid/standards/o CIM Users Group▪/default.aspxo Electric Power Research Institute (EPRI) CIM documents▪IntelliGrid Common Information Model Primer: Second Edition:/abstracts/Pages/ProductAbstract.aspx?ProductId=000000003002001040▪CIM – MultiSpeak Harmonization:/abstracts/Pages/ProductAbstract.aspx?ProductId=000000000001026585∙Esri Data Interoperability Extensiono Main site: /software/arcgis/extensions/datainteroperabilityo Training courses:▪Go to Esri Training Site:/gateway/index.cfm and type “data interoperability”into the “Find Training” s earch box.▪Free, sample course: “ArcGIS Data Interoperability Basics”/gateway/index.cfm?fa=catalog.webCourseDetail&courseid=1720∙Safe Software FMEo Safe’s FME Technology: /fme/∙CIMToolo A free open source tool that supports the Common Information Model (CIM) standards: /index.htmlDisclaimer/Notice: This CIM XML data translation template and the information, documentation and materials related thereto are provided “AS IS” on a no-fee basis without warranty of any kind, express or implied, including, but not limited to, the warranties of merchantability or fitness for a particular purpose and non-infringement of intellectual property rights.

Designing and Manufacturing an Appropriate Technology Shredder in a Developing CountryJeffrey P. WeissAn Engineering Project submitted to the faculty of the School of Engineering in partial fulfillment of the requirements of the Masters of Manufacturing Systems Engineering degreeUniversity of St. ThomasSt. Paul, MinnesotaDecember 2005AbstractThe focus of this project was to redesign a simple manual shredding machine used to shred breadfruit for the Republic of Haiti. A breadfruit shredder previously designed by a student senior design team was used as the basis for this project. The objective was to apply manufacturing principles, such as Design for Manufacturing and Assembly (DFMA), to simplify and reduce the cost of this machine so that it would be more accessible to poor farmers in Haiti. Each part of the shredder was examined using the DFMA methodology to determine if it could be eliminated or redesigned to simplify it while still making a quality product that met the performance criteria. The limitations of manufacturing a product in a developing country were also taken into consideration and played a key role in the outcome of the design. The result was a design that had a reduced number of parts, was more robust, easier to clean, simpler to build in a developing country, used materials that were more commonly available, and cost less to make.Revised Tommy Breadfruit ShredderAcknowledgementsI would like to acknowledge and send my sincerest thanks to my Project Committee of Dr. Camille George, Dr. Fred Zimmerman, and Mr. John Walker. They contributed numerous ideas during both the project phase and during the writing process. This resulted in a much better product that will hopefully improve the lives of people around the world. Dr. George also spent a great deal of time correcting and critiquing the writing of someone who was unaccustomed to writing in the academic thesis style.Many other people also lent a voice to the project during the research and design review phases. This would include Karl Mueller, Bruce Humphrey, Hank Garwick, Dave Elton, John Schevenius, Gary Olmstead, Fred Hegele, Pat O'Malley, Troy Pontgras, Yvonne Ng, and Clay Solberg. These people took the time to help and offered ideas that had previously been missed, resulting in a better product.I would also like to acknowledge the contribution of Dr. Mike Hennessey at the University of St. Thomas and the work of five of his undergraduate students. Justin Jackelen, Michael Boston, Angela Wachira, Keli Lais, and Matt Ellision took on the task of turning the revised breadfruit shredder drawings into computer animated Solidworks models. This contributed greatly to the visual understanding of the project and presentation. They also provided the fabrication prints that accompany this paper.Table of ContentsChapter I: Introduction (1)The Haitian Situation (2)Breadfruit (3)The Tommy Shredder (5)The Beneficiaries (5)Project Motivation (6)Chapter II: Research and Prior Work (7)UST Senior Design Team Work (7)Literature Search (9)Compatible Technology, International (11)Institutional Libraries (15)Research and International Organizations (15)Expert Inquires (17)Chapter III: Project Proposal (18)Project Objectives (18)Alternative Methods (20)Project Constraints (21)Project Budget (23)Financial Justification (23)Chapter IV: Findings and Results (24)Redesign Process (25)Design for Manufacture and Assembly Process (25)Alternative Designs (29)Design Reviews (30)Design Modifications (33)Fabrication Lessons (38)Design Variations (40)Shredder Blade Project (41)Testing the Redesigned Shredder (45)Redesign Results (47)Schedule (50)Final Budget (51)Chapter V: Discussion and Ramifications (52)Project Dissemination (52)Implementing the Shredder in Developing Countries (53)Project Obstacles (54)Bibliography: (57)Appendices (60)Appendix 1: Revisions 1 and 2 (60)Appendix 2: Revisions 3 and 4 (61)Appendix 3: Revisions 5 and 6 (62)Appendix 4: Revision 7 and 8 (63)Appendix 5: Breadfruit Shredder Exploded Layout (64)Appendix 6: Bill of Materials – Breadfruit Shredder (65)Appendix 7: Frame Plate Fabrication (67)Appendix 8: Drive Shaft Fabrication (69)Appendix 9: Feeder Tube Fabrication (70)Appendix 10: Blade Mount Fabrication (71)Appendix 11: Shredder Press Weight Fabrication (73)Appendix 12: Shredder Assembly Instructions (74)Appendix 13: Original Project Schedule (77)Appendix 14: Revised Project Schedule (78)Appendix 15: Preliminary Sketch by John Walker (79)Appendix 16: Contributions by Karl Mueller (80)Appendix 17: Drawing #001 – Frame Plate (82)Appendix 18: Drawing #002 – Drive Shaft (83)Appendix 19: Drawing #003 – Feeder Tube (84)Appendix 20: Drawing #004 – Drive Shaft Bearing (85)Appendix 21: Drawing #005 – Handle (86)Appendix 22: Drawing #006 – Blade Mount (87)Appendix 23: Drawing #007 – Center Divider (88)Appendix 24: Drawing #008 – Center Divider Spacer Tube (89)Appendix 25: Drawing #009 – Shredder Press Weight (90)Table of FiguresFigure 1: Map of the Republic of Haiti (CIA Fact Book, 2005) (3)Figure 2: Fruit of the Breadfruit Tree () (4)Figure 3: Senior Design Team Shredder (8)Figure 4: Garwick/Elton Breadfruit Shredder (13)Figure 5: Garwick/Elton Bicycle Drive Mechanism (14)Figure 6: Original Tommy Shredder Exploded View (28)Figure 7: Handle/Drive Shaft Changes (34)Figure 8: Drive Shaft Bearing Changes (35)Figure 9: Frame Plate Changes (35)Figure 10: Center Divider Changes (36)Figure 11: Blade Mount Changes (37)Figure 12: Combined Feeder Tube Hoop and Spacer (38)Figure 13: Alignment of Bushing Supports (39)Figure 14: Wooden Bushing Variation (41)Figure 15: Shredder Blade Profile Die, Profile Punch, and Hole Template (43)Figure 16: Fabricated Blade (45)Figure 17: The Revised Tommy Shredder (48)Table of TablesTable 1: Haiti Facts (CIA Fact Book, 2005) (2)Table 2: Proposed Budget (23)Table 3: Shredder Punch Hole Test (44)Table 4: Final Budget (52)Chapter I: IntroductionThis project will focus on redesigning for manufacture a simple breadfruit shredder for the Republic of Haiti. As one of the poorest nations in the Western hemisphere, Haiti is a country that lacks a stable government, education system, manufacturing base, or infrastructure. Malnutrition is a problem to the extent that the United States Department of State estimated that the child malnutrition rate was 22 percent in 2000(). Breadfruit is a natural food resource that is underutilized because it rots quickly and is difficult to store using traditional methods. Drying breadfruit can extend its shelf life and this process is best done when the shreds are even and consistent.A simple manual shredder was developed to produce consistent shreds for the inhabitants of Haiti by a group of senior engineering students at the University of Saint Thomas (UST) in conjunction with Compatible Technology International (CTI), an international non-profit organization. The student version of the shredder was designed and tested and found to meet all of the criteria that they had established. Despite meeting the requirements, the machine had the potential to be optimized to better reflect the manufacturing capabilities available in a developing country. This paper will document the redesign process and look at the manufacturing principles that drove this process. The end result was a machine that was simpler to build with the basic machine tools that would normally be found in a developing country such as Haiti, used materials that were more commonly available, had a reduced number of parts, was more robust, was easier to clean, and had a reduced cost.The Haitian SituationHaiti is considered to be the poorest and most destitute country in the Western hemisphere (CIA Fact Book, 2005). A majority of its population lives in poverty and relies on subsistence farming for survival. It has a long history of political upheaval and unrest since it gained its independence from France in 1804. The rotation of various governments and civil wars has hindered investment in the country and led to high unemployment and dismal living conditions for its inhabitants. The education system is broken or non-existent and there has been an exodus of knowledge from the island as people flee the dire conditions and turmoil.Table 1: Haiti Facts (CIA Fact Book, 2005)Population (Estimate, 2004): 8,121,622Land Area: 27,750 sq kmAverage Life Expectancy: 53 yearsPopulation Below Poverty Line: 80%Percentage of Population in Agriculture: 66%Unemployment Rate (no formal job): 66%Average Literacy Rate: 52%Figure 1: Map of the Republic of Haiti (CIA Fact Book, 2005)Most of the original Haitian forests have been cut down for fuel and the desire to cultivate more land. The weak governments have been unable or unwilling to confront this problem and it has continued unchecked. This deforestation has resulted in massive land erosion in the mountainous country and a net loss of arable land (CIA Fact Book, 2005). Breadfruit trees are abundant throughout the island and are one of the few trees that have survived the deforestation process.BreadfruitBreadfruit is an important food source and has become a staple for the inhabitants of warmer islands in the Caribbean Sea and Pacific Ocean. It has some nutritional value anda high starch content (Adebowale, 2005). Typical ways of preparing breadfruit are grilling, roasting, adding it to soups, and mashing.Figure 2: Fruit of the Breadfruit Tree ()One of the unique properties of breadfruit is its limited shelf life. Once it ripens and comes off of the tree, it will last between one and three days ( ). The breadfruit trees of Haiti produce fruit twice a year for a three week period (six weeks per year). Much of the fruit rots on the ground because of the inability to consume it all for the short time that it is in season (Capecchi, 2005). Typical preservation methods for fruit, such as canning, can be done but these value-adding processes are not common in Haiti and will increase the price of the food. A more economical way of preserving the breadfruit needed to be developed to utilize its potential to alleviate long-term hunger on the island.The Tommy ShredderThe development of a breadfruit harvesting process was taken on by two groups of senior mechanical engineering students as their Senior Design Projects in the 2003-2004 academic year. The first team attempted to devise a solar drier to quickly dehydrate the shredded breadfruit. The drying project showed that the shredded fruit could be successfully air-dried with an optimal shred size of ½” wide (Emiliusen, Mauritzen, McGruder, and Torgerson, 2004). The dried product can be stored for up to a year.The second team worked on developing a small, economical shredder that could efficiently and quickly process the breadfruit down into shreds so that it could be dried (Anderson, Fox, Rick, and Spah, 2004). The concept and methodology for the basic shredder design was done by the senior design team as was the testing to prove out the final design and will not be repeated in this paper. The purpose of this project was to examine and simplify the design, focusing primarily on its manufacturability.The BeneficiariesThe target beneficiaries of this shredder will be women’s cooperative groups based in Haiti. CTI, whose mission is to bring appropriate technologies to help increase food supplies and storage capacities in the developing world, has been working with the Methodist Church missions in Haiti on preserving breadfruit. Dried breadfruit can be ground into flour and local CTI volunteers have created several recipes using this breadfruit flour as the bulk material. UST teamed up with CTI to develop a simple shredder that could be used to shred the breadfruit. The goal of this joint project was tocreate a shredder that was simple to use and economical to manufacture so that local versions could be bought with micro-loans managed by the Methodist Church of Haiti. CTI also planned on helping set up a program to buy the shredded/ground breadfruit and process it into a cereal for Haitian school children (Capecchi, 2004). The plan was to take a resource, preserve it and add value, and then process it to create a commercial good. The objective of this undertaking is to give the women’s co-ops a starter model shredder that would allow them to generate some income from a readily available raw material.This shredder is also capable of processing a variety of different produce. There have been inquiries into its ability to shred cassava, sweet potatoes, and red peppers. The alternative uses of the shredder will not be explored here but the final design for this project will be made readily available and has potential uses worldwide. It will also be submitted to appropriate technology journals to broaden its dissemination.Project MotivationThe author of this master’s engineering project has spent time in developing countries and realized that there are often raw materials that are not fully utilized and exploited. The people generally lack the knowledge to manufacture items in large volumes and have limited manufacturing equipment, start-up money, a reliable source of power, or an infrastructure to transport the goods (Obi, 1999). However, these people are extremely creative and will adapt what they have on hand to work in almost any situation (Humphrey, 2005). The motivation for this project was to help the people develop theirown economy and hopefully raise their standard of living. This project will not only benefit the women of Haiti, it will help the local machine shops, provide work at the processing plant, and give the children of Haiti a stable, year around diet.Chapter II: Research and Prior WorkThe research for this project consisted of searching major journals, books on manufacturing in developing countries, contacting major research libraries, and personal contacts with experts in various fields. Many avenues for help were explored to gather information to improve the final design. The research phase of this project found that the work done by the UST senior design team was one of the few to address the issue of constructing a simple shredder for manufacture and use in a developing country.UST Senior Design Team WorkThis project is based on the work previously done by a University of Saint Thomas (UST) senior engineering design team whose goal was to develop the original breadfruit shredder based on the needs of the country of Haiti and the criteria established by Compatible Technology, International (CTI). The purpose of the original project was to “find the most efficient means of mechanically shredding breadfruit to best prepare the fruit for the drying process” (Anderson et al, 2004). The team developed concepts and tested many different methods of shredding the breadfruit and the mechanical actuators that would be needed for each prototype. The concepts were evaluated and ranked and the team chose the method best suited for their needs. The ‘Tommy Shredder’ developedby the student senior design team is shown in Figure 3 and their paper can be found on the UST website at /cmgeorge/breadfruit_shredder/.Figure 3: Senior Design Team ShredderThe senior design team had originally planned on testing the shredder in its target environment of Haiti but that country was not accessible at the time due to political unrest. A prototype shredder was built and brought to the Caribbean island of St. Vincent where there was an ample supply of breadfruit and established contacts. On the island of St. Vincent, the design was field-tested using breadfruit and the results recorded. The shredder met all of the target criteria established by CTI and the design team. It produced an average shred rate of 200 pounds/hour and cost less than $100 dollars U.S. to build (Anderson et al, 2004). This shredder became the baseline for the current project.Literature SearchA literature search done using the Compendex database at the University of Minnesota found several articles that were possibly related or relevant to the design of the breadfruit shredder. These articles were retrieved and analyzed with the result being that a majority were not related or did not contain information relevant to the design of an appropriate technology machine. Many of the applicable articles are referenced throughout this paper while those with less relevance to the project are cited in this section.In ‘Functional Properties of Native, Physically and Chemically Modified Breadfruit (Artocarpus Artilis) Starch’, Adebowale, Olu-Owolabi, Olawumi, and Lawal (2005) dealt with extracting starch from breadfruit. In the ‘Rediscovery of Local Raw Materials: New Opportunities for Developing Countries’, El-Mously (1997) discussed ways that developing countries could use local, undervalued resources to reduce their dependence on foreign imports. Breadfruit would be an undervalued resource on most Caribbean islands but the article did not provide information that would be relevant to the design of a shredder or this project. In the ‘Framework for Selecting and Introducing Appropriate Production Technology in Developing Countries’, Bruun and Mefford (1996) looked at working with the culture and education of developing countries when setting up a production facility. These are issues that will not be dealt with in this paper. In the ‘Role of Materials in Developing Countries’, Villas-Boas (1990) discussed the lack of use of new, high-tech materials in developing countries due to their cost and availability. Every effort was made to design the shredder using only common materials that would typicallybe available in a poor, developing country. In the ‘Supplier Selection in Developing Countries: a Model Development’, Motwani, Youssef, Kathawala, and Futch (1999) discussed issues involving selecting or qualifying vendors to produce a product. This will be the responsibility of the organization having the shredder built, and is beyond the scope of this project.A search of the Internet using the Google – Advanced Scholar provided more papers that had some relevance. Thakur, Varma, and Goldey (2001) in the ‘Perceptions of Drudgery in Agriculture and Animal Husbandry Operations: A Gender Analysis From Haryana State, India’ discusses the fact that women in developing countries spend much more time working in agriculture than men and the tasks given to them are more monotonous and tedious. The article supports the need for a device like the breadfruit shredder that has the potential to lift them out of that situation. In ‘A Framework for Implementing Appropriate Manufacturing Systems in Developing Economies’, Obi (1999) looked for explanations on why the Industrial Revolution passed by most developing countries and explored ways that these countries can start utilizing their vast manpower resources. He discusses the need to change workers attitudes. Finally, in ‘Meeting a Pressing Need’, Hynd and Smith (2004) discuss a simple oilseed ram press as an appropriate technology device for small scale extracting of oil from seeds and nuts. They examine some of the cultural issues that were associated with implementing the oilseed ram. The insights of this article could be used as a guide for undertaking the next phase of the shredder project; implementation into the Haitian culture. They briefly talk about some of themanufacturing difficulties, such as poor quality, associated with producing goods in a developing country.The best book relating to appropriate technology equipment used in developing countries is the ‘Appropriate Technology Sourcebook’ compiled by Darrow and Saxenian (1993). It is considered ‘The Bible’ by people in the appropriate technology field, such as those at CTI (Humphreys, 2005). The book is a resource listing appropriate technology machine books and papers that are available for purchase from other sources. It does not contain any designs of its own, but it does give a brief description of the contents of the papers and designs that are available for order. A search of this book and the updated website did not reveal any designs for manual shredders or grinders(/atnetwork/atsourcebook/index).Compatible Technology, InternationalCompatible Technology, International (CTI) () is an excellent local resource for dealing with appropriate technology in developing countries and has extensive connections throughout the world. It is an organization dedicated to using simple devices to improve food production and storage in the third world. They are a stakeholder in the design and development of the original shredder. The director of CTI is Bruce Humphreys who granted an interview on issues dealing with manufacturing in developing countries (2005). Some of the key points that he brought up were:Manufacturers in developing countries do not necessarily build parts to a fabrication print. Everything is custom and will look similar to what is desired,but is not quite the same.Creativity is not rewarded in many cultures and there is a desire to continue doing things the old way.Expectations in quality and standards will probably not be met. They do not typically produce to the same quality as is expected in the U.S.There are cultural norms and practices that will be slow to change and may not be overcome. This would primarily relate to the target market of women. Womentend to not use machines, thus the design must be easy to use and relatively toolfree.These assertions by Mr. Humphrey were reinforced in other literature relating to the topic (Obi, 1999).Hank Garwick and Dave Elton are the two CTI volunteers who are most closely tied into the Haiti mission. They have made several trips to Haiti on humanitarian missions associated with both CTI and the Methodist Church. The two offered insight into the Haitian mindset, manufacturing capabilities in Haiti, and experience in shredding breadfruit. Their comments on the manufacturing capabilities in Haiti were that “we would be lucky to find someone who could read a print, and even if they can they probably won’t follow it” (Garwick, 2005).Garwick and Elton were not satisfied with the work of the UST senior design team and continued to develop the shredder after the senior design team’s project ended. They made several small modifications to the design, built a prototype, and brought it down to Haiti to be tested (Fig. 4). The Garwick/Elton version of the shredder did not work as well as intended and did not produce the desired shred rate found by the UST engineering team (Garwick, 2005). It is unclear why this was the case. Several of the better design changes that they made to their shredder were incorporated into the current shredder design. These would include the sheet metal center divider and ideas on the retainer for the shredding blade.Figure 4: Garwick/Elton Breadfruit ShredderGarwick and Elton believed strongly that the prime power for the operation of the shredder should be a leg driven bicycle type mechanism instead of the current hand powered crank. Figure 5 shows a bicycle drive assembly that they added to a shredder (Garwick, 2005). This project is focused on producing a shredder for the poorest of people in Haiti and it was felt that a bicycle type mechanism would significantly add to the cost of the machine while making it unnecessarily complex. It is expected that this shredder will only be fully utilized for several weeks a year during the breadfruit harvest and would not justify the higher cost. The current design is one such that a bicycle type drive could be added to the shredder at a later date if desired by the user.Figure 5: Garwick/Elton Bicycle Drive MechanismInstitutional LibrariesThe United States Military Academy at West Point has an extensive library relating to military manuals and papers. The U.S. military routinely performs operations in developing countries and the units typically tasked with helping the local population are the Civil Affairs units and the Special Operations Forces. These units are often involved in nation building and community development and have close contact with the people. Daniel Prichard, a research librarian at the library, was contacted about any pamphlets, articles, or papers that the library may have on a shredder or appropriate technologies in developing countries. Mr. Prichard found nothing relevant at the Academy’s library (Prichard, 2004).A search of the University of St. Thomas’s and the University of Minnesota’s library systems found no books or on-site literature that was relevant to the design of the breadfruit shredder.Research and International OrganizationsThe Hawaiian Breadfruit Institute is an organization based in Hawaii whose mission is “to promote the study and use of Breadfruit for food and reforestation”( ). It tracks and propagates the 120 known varieties of breadfruit found on the islands of the Pacific Ocean and Caribbean Sea. Dr. Diane Ragone, director of the Hawaiian Breadfruit Institute, was contacted regarding the shredding of breadfruit and the possible existence of similar devices. Dr. Ragone responded that she had not heard of any similar processing methods for breadfruit. Her primary concern for this wasthat the latex found naturally in breadfruit would ‘gum-up’ the machine and clog the shredding blade (Ragone, 2005). This issue was raised with Hank Garwick of CTI and he stated that most of the latex in breadfruit was found in the skin. The skin is removed before processing so this did not appear to be a concern for the shredder. The field tests in St. Vincent by the senior engineering student team did not report any excessive latex build up on the blades.The International Research Development Centre (IRDC) is a Canadian based organization whose purpose is ‘to build healthier, more equitable, and more prosperous societies’ (www.irdc.ca ). An e-mail was sent to IRDC explaining the project and asking about any information that they might have on shredders. The response was a link to their website which brought up nothing of value. A similar search of the United Nations Development Program (UNDP) provided no additional information ().Research was done with the United States Food and Drug Administration (FDA) to see if there were requirements or recommendations for the food industry regarding food processing equipment or the components used in them. The purpose was to find out which materials were considered “Food Grade” and suitable for food contact. The goal is to make the shredder as sanitary and safe as possible regardless of the standards that may be present in a developing country. It was found that the FDA does not keep a list of recommended materials, but has established a list of requirements that manufactures must meet in order to state that it is a material approved for food contact. The premise of therequirements are that if any of the material could ‘migrate’ to the food, it must not pose a threat to humans (FDA, 1999).Expert InquiresThe Minneapolis/St. Paul area is home to several large food producing companies such as General Mills. Food Safety personnel at General Mills were contacted to ask about standards for their food production equipment and any suggestions that would help to make the shredder more sanitary and suitable for food contact. These inquiries covered guidelines that are typical of the food processing industry. Gary Olmstead, Food Safety Instructor at General Mills stated that equipment should be durable and easy to clean (Olmstead, 2005). General Mills avoids having any pieces of equipment over the product because of the risk of parts falling into the food. Fred Hegele, also part of food safety at General Mills, was concerned about the durability of any plastics used in the equipment. He emphasized that the machine cannot have any recessed pockets or hard to clean areas. These would trap bacteria and make it unsafe and unsanitary (Hegele, 2005). John Schevenius, a former General Mills Engineer and founder of CTI, was contacted about suggestions for the shredder. Although he was familiar with the breadfruit program, he could not offer any suggestions for improvement (Schevenius, 2005).The research done here showed that there is a lack of availability of information regarding the design of an appropriate technology machine. The design methodology varies from organization to organization and no standardized process appears to have been completed and published in a major journal regarding the topic. Appropriate。

Today, however, the emergence of drug resistance in bacteria is reversing the miracles of the past eighty years, with drug choices for the treatment of many bacterial infections becoming increasingly limited, expensive, and, in some cases, nonexistent . The Centers for Disease Control and Prevention (CDC) estimates that drug-resistant bacteria cause two million illnesses and approximately 23,000 deaths each year in the United States alone .The National Action Plan for Combating Antibiotic-resistant Bacteria provides a roadmap to guide the Nation in rising to this challenge . Developed in response to Executive Order 13676: Combating Antibiotic-Resistant Bacteria—issued by President Barack Obama on September 18, 2014—the National Action Plan outlines steps for implementing the National Strategy for Combating Antibiotic-Resistant Bacteria and addressing the policy recommendations of the President’s Council of Advisors on Science and Technology (PCAST) . Although its primary purpose is to guide activities by the U .S .Government, the National Action Plan is also designed to guide action by public health, healthcare, and veterinary partners in a common effort to address urgent and serious drug-resistant threats that affect people in the U .S .and around the world . Implementation of the National Action Plan will also support World Health Assembly resolution 67 .25 (Antimicrobial Resistance), which urges countries to take urgent action at the national, regional, and local levels to combat resistance .The goals of the National Action Plan include:1. Slow the Emergence of Resistant Bacteria and Prevent the Spread of Resistant Infections .2. Strengthen National One-Health Surveillance Efforts to Combat Resistance .3. Advance Development and Use of Rapid and Innovative Diagnostic Tests for Identification andCharacterization of Resistant Bacteria .4. Accelerate Basic and Applied Research and Development for New Antibiotics, OtherTherapeutics, and Vaccines .5. Improve International Collaboration and Capacities for Antibiotic-resistance Prevention,Surveillance, Control, and Antibiotic Research and Development .By 2020, implementation of the National Action Plan will lead to major reductions in the incidence of urgent and serious threats, including carbapenem-resistant Enterobacteriaceae (CRE), methicillin-resistant Staphylococcus aureus (MRSA), and Clostridium difficile (see Table 1) . The National Action Plan will also result in improved antibiotic stewardship in healthcare settings, prevention of the spread of drug-resistant threats, elimination of the use of medically-important antibiotics for growth promotion in food animals, and expanded surveillance for drug-resistant bacteria in humans and animals .Other significant outcomes include creation of a regional public health laboratory network, establishment of a specimen repository and sequence database that can be accessed by industrial and academic research-ers, development of new diagnostic tests through a national challenge, and development of two or moreNAT I ONAL ACT I ON P LAN FOR COMBAT I NG ANT I BI OT I C-RESISTANT BACT ERIA antibiotic drug candidates or non-traditional therapeutics for treatment of human disease . In addition, the effort to combat resistant bacteria will become an international priority for global health security . Progress towards achieving these outcomes will be monitored by the U .S .Government Task Force that developed the National Action Plan. The Task Force, which is co-chaired by the Secretaries of Defense, Agriculture, and Health and Human Services, includes representatives from the Departments of State, Justice, Veterans Affairs, and Homeland Security, as well as the Environmental Protection Agency, the United States Agency for International Development, the Office of Management and Budget, the Domestic Policy Council, the National Security Council, the Office of Science and Technology Policy, and the National Science Foundation . Additionally, the Presidential Advisory Council on Combating Antibiotic-Resistant Bacteria, created by Executive Order 13676, will provide advice, information, and recommendations to the Secretary of Health and Human Services regarding the National Action Plan’s programs and policies and their impact on the threat .Implementation of the objectives and activities in the National Action Plan requires sustained, coordi-nated, and complementary efforts of individuals and groups around the world, including healthcare providers, healthcare leaders, veterinarians, agriculture industry leaders, manufacturers, policymakers, and patients . All of us who depend on antibiotics must join in a common effort to detect, stop, and prevent the emergence and spread of resistant bacteria .IntroductionVision: The United States will work domestically and internationally to prevent, detect, and control illness and death related to infections caused by antibiotic-resistant bacteria byimplementing measures to mitigate the emergence and spread of antibiotic-resistance and ensuring the continued availability of therapeutics for the treatment of bacterial infections. Antibiotics have been a critical public health tool since the discovery of penicillin in 1928, saving the lives of millions of people around the world . Today, however, the emergence of drug resistance in bacteria is reversing the gains of the past eighty years, with many important drug choices for the treatment of bacterial infections becoming increasingly limited, expensive, and, in some cases, nonexistent . The Centers for Disease Control and Prevention (CDC) estimates that each year at least two million illnesses and 23,000 deaths are caused by drug-resistant bacteria in the United States alone .The loss of antibiotics that kill or inhibit the growth of bacteria means that we can no longer take for granted quick and reliable treatment of rare or common bacterial infections, including bacterial pneu-monias, foodborne illnesses, and healthcare-associated infections . As more strains of bacteria become resistant to an ever larger number of antibiotics, we will also lose the benefits of a range of modern medi-cal procedures—from hip replacements to organ transplants—whose safety depends on our ability to treat bacterial infections that may arise as post-surgical complications . Moreover, antibiotic-resistance also threatens animal health, agriculture, and the economy .The National Action Plan for Combating Antibiotic-resistant Bacteria provides a roadmap to guide the Nation in rising to this challenge . The National Action Plan outlines steps for implementing the National Strategy for Combating Antibiotic-Resistant Bacteria and addressing the policy recommendations of the President’s Council of Advisors on Science and Technology . Although its primary purpose is to guide activities by the U .S .Government, the National Action Plan is also designed to guide action by public health, healthcare, and veterinary partners in a common effort to address urgent and serious drug-resistant threats (Table 3) that affect people in the U .S .and around the world .Goals of the National Action PlanThe National Action Plan—informed by the guiding principles in Table 2—is organized around five goals for collaborative action by the U .S .Government, in partnership with foreign governments, individuals, and organizations aiming to strengthen healthcare, public health, veterinary medicine, agriculture, food safety, and research and manufacturing . Aggressive action will move the nation towards major reductions in the incidence of urgent and serious drug-resistant threats (Table 3), including carbapenem-resistant Enterobacteriaceae (CRE), methicillin-resistant Staphylococcus aureus (MRSA), and Clostridium difficile.•Misuse and over-use of antibiotics in healthcare and food production continue to hasten the development of bacterial drug resistance, leading to loss of efficacy of existing antibiotics .•Detecting and controlling antibiotic-resistance requires the adoption of a “One-Health” approach to disease surveillance that recognizes that resistance can arise in humans, animals, and the environment .•Implementation of evidence-based infection control practices can prevent the spread of resistant pathogens .•Interventions are necessary to accelerate private sector investment in the development of therapeutics to treat bacterial infections because current private sector interest in antibiotic development is limited .•Researchers can use innovations and new technologies—including whole genome sequencing, metagenomics, and bioinformatic approaches—to develop next-generation tools to strengthen human and animal health, including:−Point-of-need diagnostic tests to distinguish rapidly between bacterial and viral infections as well as identify bacterial drug susceptibilities;−New antibiotics and other therapies that provide much needed treatment options for those infected with resistant bacterial strains; and−Antibiotic resistance is a global health problem that requires international attention and collaboration, because bacteria do not recognize borders .1. The TB activities identified in the NAP are included as they represent critical near-term public health activities that will support progress to reduce the burden of drug-resistant TB in the U .S . Additional domestic and global activitiesto address drug-resistant TB will be provided in a companion action plan specific to TB and will be submitted to the President no later than September, 2015 . The companion action plan will build on recommendations of the Federal TB Task Force (http://www .cdc .gov/mmwr/pdf/rr/rr5803 .pdf) as well the work of the interagency USG TB working group . Those goals include:GOAL 1: Slow the Emergence of Resistant Bacteria and Prevent the Spread of Resistant Infections. Judicious use of antibiotics in healthcare and agricultural settings is essentialto slow the emergence of resistance and extend the useful lifetime of effective antibiotics .Antibiotics are a precious resource, and preserving their usefulness will require cooperationand engagement by healthcare providers, healthcare leaders, pharmaceutical companies,veterinarians, the agricultural industry, and patients . Goal 1 activities include the optimaluse of vaccines to prevent infections, implementation of healthcare policies and antibioticstewardship programs that improve patient outcomes, and efforts to minimize the develop-ment of resistance by ensuring that each patient receives the right antibiotic at the right timeat the right dose for the right duration. Prevention of resistance also requires rapid detectionand control of outbreaks and regional efforts to control transmission across community andhealthcare settings .GOAL 2: Strengthen National One-Health Surveillance Efforts to Combat Resistance. Improved detection and control of drug-resistant organisms will be achieved through an integrated,“One-Health” approach that includes the enhancement and integration of data from surveil-lance systems that monitor human pathogens—including the National Healthcare SafetyNetwork (NHSN), the Emerging Infections Program (EIP), and the National AntimicrobialResistance Monitoring System (NARMS)—with data from surveillance systems that monitoranimal pathogens—including the National Animal Health Monitoring System (NAHMS),the National Animal Health Laboratory Network (NAHLN), and the Veterinary LaboratoryInvestigation and Response Network (Vet-LIRN) . Goal 2 activities include creation of aregional public health laboratory network that provides a standardized platform for resistancetesting and advanced capacity for genetic characterization of bacteria (e .g ., through wholegenome sequencing) . Goal 2 activities will also enhance monitoring of antibiotic sales, usage,resistance, and management practices at multiple points along in the food-production chain,from farms to processing plants to supermarkets .GOAL 3: Advance Development and Use of Rapid and Innovative Diagnostic Tests for Identification and Characterization of Resistant Bacteria. Improved diagnostics fordetection of resistant bacteria and characterization of resistance patterns will help healthcareproviders make optimal treatment decisions and assist public health officials in taking actionto prevent and control disease . Improved diagnostics will also help decrease unnecessaryor inappropriate use of antibiotics . Goal 3 activities will accelerate the development of newdiagnostics and expand their availability and use to improve treatment, enhance infectioncontrol, and achieve faster response to infections and outbreaks caused by resistant bacteriain hospitals and in the community .GOAL 4: Accelerate Basic and Applied Research and Development for New Antibiotics, Other Therapeutics, and Vaccines. Despite the urgent need for new antibiotics, the number ofproducts in the drug-development pipeline is small and commercial interest remains limited .The advancement of drug development—as well as non-traditional therapeutics and vac-cines—will require intensified efforts to boost scientific research, attract private investment,and facilitate clinical trials of new drug candidates . Goal 4 activities will help accomplish theseobjectives by supporting basic and applied research, providing researchers with scientificservices (e .g ., specimens, sequence data, and regulatory guidance), and fostering public-private partnerships that strengthen the clinical trials infrastructure and reduce the risks,uncertainty, and obstacles faced by companies who are developing new antibiotics and/orother therapeutics and vaccines that can impact the use of antibiotics and the developmentof resistance .GOAL 5: Improve International Collaboration and Capacities for Antibiotic-resistance Prevention, Surveillance, Control, and Antibiotic Research and Development. Antibioticresistance is a worldwide problem that cannot be addressed by one nation in isolation . Goal5 activities include working with foreign ministries of health and agriculture, the World HealthOrganization (WHO), the Food and Agriculture Organization (FAO), the World Organizationfor Animal Health (OIE), and other multinational organizations to enhance global capacity todetect, analyze, and report antibiotic use and resistance, create incentives for the develop-ment of therapeutics and diagnostics, and strengthen global efforts to prevent and controlthe emergence and spread of antibiotic-resistance . To advance these objectives, U .S .agencieswill support development of a WHO Global Action Plan on Antimicrobial Resistance, enhanceinternational collaborations including cooperation under the European Union-United StatesTrans-Atlantic Task Force on Antimicrobial Resistance (TATFAR), and mobilize global healthresources through the Global Health Security Agenda .Development of the National Action PlanThe National Action Plan was developed in response to Executive Order 13676: Combating Antibiotic-Resistant Bacteria (Appendix 2), which was issued by President Barack Obama on September 18, 2014 in conjunction with the National Strategy for Combating Antibiotic-Resistant Bacteria.The Executive Order calls for a U .S .Government Task Force to create a five-year action plan that lays out steps and milestones for achieving the Strategy’s goals and objectives (Table 2) and addressing the PCAST recommendations . The Task Force, which is co-chaired by the Secretaries of Defense, Agriculture, and Health and Human Services, includes representatives from the Department of State, the Department of Justice, the Department of Veterans Affairs, the Department of Homeland Security, the Environmental Protection Agency, the United States Agency for International Development, the Office of Management and Budget, the Domestic Policy Council, the National Security Council staff, the Office of Science and Technology Policy, and the National Science Foundation .Development of the National Action Plan also supports World Health Assembly (WHA) resolution 67 .25 (Antimicrobial Resistance), which was endorsed in May 2014 and urges countries to develop and finance national plans and strategies and take urgent action at the national, regional, and local levels to combat resistance . The resolution urges WHA Member States to develop practical and feasible approaches to, among other actions, extend the lifespan of drugs, strengthen pharmaceutical management systems and laboratory infrastructure, develop effective surveillance systems, and encourage the development of new diagnostics, drugs, and treatment options .These recommendations are intended to inform the policy development process, and are not intended as a budget document . The commitment of resources to support these activities will be determined through the usual Executive Branch budget processes . Implementation of some of the actions in this report will require additional resources and these resources could be new or redirected from lower-priority Agency activities .Monitoring and EvaluationThe Task Force created under Executive Order 13676 is charged with providing the President with annual updates on Federal Government actions to combat antibiotic resistance, including progress made in implementing the National Action Plan, plans for addressing obstacles and challenges, and recommenda-tions for new or modified actions . The Presidential Advisory Council on Combating Antibiotic-Resistant Bacteria will provide advice, information, and recommendations to the Secretary of Health and Human Services regarding the programs and policies developed in the National Action Plan .Partnerships and ImplementationImplementation of the National Action Plan will require the sustained, coordinated, and complemen-tary efforts of individuals and groups around the world, including public and private sector partners, healthcare providers, healthcare leaders, veterinarians, agriculture industry leaders, manufacturers, policymakers, and patients . All of us who depend on antibiotics must join in a common effort to detect, stop, and prevent the emergence and spread of resistant bacteria .NAT I ONAL ACT I ON P LAN FOR COMBAT I NG ANT I BI OT I C-RESISTANT BACT ERIAGOAL 1. Slow the Emergence of Resistant Bacteria and Prevent the Spread of Resistant InfectionsJudicious use of antibiotics in healthcare and agricultural settings is essential to slow the emergence of resistance and extend the useful lifetime of effective antibiotics . Antibiotics are a precious resource, and preserving their usefulness will require cooperation and engagement by healthcare providers, healthcare leaders, pharmaceutical companies, veterinarians, the agricultural industry, and patients . Effective dissemination of information to the public is critical . Prevention of resistance also requires rapid detection and control of infections and outbreaks (see also Goal 2) and regional efforts to control transmission across community and healthcare settings .Goal 1 includes activities to foster antibiotic stewardship by improving prescribing practices across all healthcare settings, prevent the spread of drug-resistant threats in healthcare facilities and communities, and reduce and eventually eliminate the use of medically-important antibiotics for growth promotion in animals .By 2020, significant outcomes of Goal 1 will include:•Establishment of antibiotic stewardship programs in all acute care hospitals and improved antibiotic stewardship across all healthcare settings .•Reduction of inappropriate antibiotic use by 50% in outpatient settings and by 20% in inpatient settings .•Establishment of State Antibiotic Resistance (AR) Prevention (Protect) Programs in all 50 states to monitor regionally important multidrug resistant organisms and provide feedback and technical assistance to healthcare facilities .Actions taken to achieve Goal 1 will fulfill:• Executive Order 13676, Sections 5 and 7:−Improved Antibiotic Stewardship−Preventing and Responding to Infections and Outbreaks with Antibiotic-Resistant Organisms• Provisions in PCAST Recommendations #2, #6, and #7:−Effective Surveillance & Response for Antibiotic-resistance−Improving Stewardship of Existing Antibiotics in Health Care−Limit the Use of Antibiotics in Animal Agriculture•Elimination of the use of medically-important antibiotics for growth promotion in food-pro-ducing animals .•Requirement of veterinary oversight for use of medically-important antibiotics in the feed or water of food-producing animals .1.1 Implement public health programs and reporting policies that advanceantibiotic resistance prevention and foster antibiotic stewardship inhealthcare settings and the community.Perhaps the single most important action to slow the development and spread of antibiotic-resistant infections is to change the way antibiotics are used . Antibiotics are overprescribed in both human and animal settings, which makes everyone less safe . Investments in this area will be used to develop education and outreach programs to clarify and strengthen responsible, appropriate use of antibiotics in humans and animals . Efforts in this area will help greatly in slowing down the spread of resistant bacteria . This commitment to always use antibiotics appropriately and safely—to use the right antibiotic at the right time at the right dose for the right duration—is known as antibiotic stewardship.Sub-Objective 1.1.1A: Strengthen antibiotic stewardship in inpatient, outpatient, and long-term care settings by expanding existing programs, developing new ones, and monitoring progress and efficacy .The establishment and expansion of antibiotic stewardship programs will improve patient outcomes and minimize the development of resistance by ensuring judicious use of antibiotics .Milestones for provision of educational materials to enhance antibiotic stewardship in outpatient settings are provided under Sub-Objective 1 .1 .1B .MilestonesWithin one year:•The Departments of Health and Human Services (HHS), Defense (DOD), and Veterans Affairs (VA) will review existing regulations and propose new ones, as needed, requiring hospitals, ambulatory surgery centers, dialysis facilities, and other inpatient facilities to implement robust antibiotic stewardship programs that align with the CDC Core Elements. HHS, DOD, and VA will also work together to optimize standardization of stewardship programs and activities, including monitoring activities and reporting criteria .•The National Healthcare Safety Network (NHSN) will begin tracking the number of healthcare facilities with stewardship policies and programs in place .•DOD will establish a multidisciplinary group, under the purview of the Assistant Secretary of Defense for Health Affairs, to support and coordinate stewardship activities across DOD .Within three years:•All hospitals that participate in Medicare and Medicaid programs must comply with Conditions of Participation (COP) . The Centers for Medicare & Medicaid Services (CMS) will issue new COPs or revise current COP Interpretive Guidelines to advance compliance with recommendations in CDC’s Core Elements of Hospital Antibiotic Stewardship Programs. HHS, DOD, and VA will also implement policies that:−Encourage implementation of antibiotic stewardship programs as a condition for receiving Federal grants for health care delivery (e .g ., in community healthcare centers) .−Require health facilities operated by the U .S . Government to develop and implement antibiotic stewardship programs and participate in NHSN reporting (see Objective 2 .2) .•All acute care hospitals governed by the CMS COP will implement antibiotic stewardship pro-grams . CMS will expand COP requirements to apply to long-term acute care hospitals, other post-acute facilities, ambulatory surgery centers, and dialysis centers .•CMS will revise existing Interpretive Guidelines (IGs), as needed, to include antimicrobial steward-ship improvements . For example, IGs on Quality Assurance and Performance Improvement for hospitals may incorporate antibiotic-stewardship performance measures developed by the CDC, the Agency for Healthcare Research and Quality (AHRQ), or other professional organizations .•Training webinars for CMS surveyors will be updated to include information on antibiotic utilization in nursing homes, in accordance with existing IGs in the Infection Control Nursing Home regulations .•CDC, CMS, AHRQ, and other partners will issue guidance on antibiotic stewardship and best practices for ambulatory surgery centers, dialysis centers, nursing homes and other long-term care facilities, doctors’ offices and other outpatient settings, pharmacies, emergency depart-ments, and medical departments at correctional facilities .•At least 25 States, the District of Columbia, and Puerto Rico will establish or enhance antibiotic stewardship activities in inpatient healthcare delivery settings, in accordance with the CDC Core Elements . CDC will support these efforts via State AR Prevention (Protect) Programs for Healthcare (“AR Protect Programs”; see also Sub-Objective 1 .1 .2) .Within five years:•DOD will support antibiotic stewardship programs and interventions critical for maintaining quality health care throughout the Military Healthcare System (MHS) .•CDC will work with select hospital systems to expand antibiotic use reporting and steward-ship implementation, and will partner with nursing organizations to develop and implement stewardship programs and interventions in a set of nursing homes .•All states will establish or enhance antibiotic stewardship activities in healthcare delivery settings .Sub-Objective 1.1.1B: Strengthen educational programs that inform physicians, veterinari-ans, members of the agricultural industry, and the public about good antibiotic stewardship .Educational programs that promote good antibiotic stewardship in healthcare settings include:•Get Smart: Know When Antibiotics Work . Many antibiotics prescribed in doctors’ offices, clinics, and other outpatient settings are not needed . This program focuses on appropriate antibiotic prescribing and use for common illnesses in children and adults .•Get Smart for Healthcare. Many patients in hospitals, nursing homes, and other healthcare facili-ties receive antibiotics to fight infections, but these drugs are often prescribed incorrectly . This program helps clinicians prescribe the right drugs for the right patients at the right doses and times . The United States Department of Agriculture (USDA), CDC, and the Food and Drug Administration (FDA) will also continue to work with partners in the agriculture industry to advance appropriate use of antibiotics in food animals and promote collaborations among partners in medicine, veterinary medicine, and public health .Additional milestones for provision of educational materials to enhance antibiotic stewardship in agri-cultural settings are provided under Sub-Objectives 1 .2 .3 and 1 .3 .1 .MilestonesWithin one year:•CDC and VA will apply lessons learned from the CDC and VA pilot project to provide clinicians with support for making prescribing decisions based on judicious use of antibiotics and will submit a manuscript for publication describing initial research findings from this effort . Within three years:•CDC will support public health departments in establishing statewide programs for antibiotic stewardship and appropriate antibiotic use . These programs will identify healthcare facilities with high antibiotic-prescribing rates and use lessons learned from the CDC and VA pilot project (see above) and other best practices to improve antibiotic prescribing in these facilities . The success of these efforts will be assessed by measuring changes in prescribing rates and in clini-cians’ understanding of antibiotic stewardship activities and programs .•CDC will provide technical assistance to Federal facilities (e .g ., those operated by DOD, the VA, and the Indian Health Service) and other large health systems in scaling up implementation and assessment of interventions to improve outpatient antibiotic prescribing, extending effective interventions to long-term care settings, and ensuring long-term sustainability of antibiotic stewardship efforts .•DOD will initiate the planning and approval process to modify clinical decision-support interven-tions in DOD facilities in targeted regions .•CDC, CMS, and partners will propose expanded quality measures for antibiotic prescribing .。

Specifically, it is the commitment of time, energy, and resources to a relatively narrow field of study and the creative energy necessary to generate new knowledge in that field. It takes a considerable amount of time and regular exposure to a large number of cases to become an expert。
An individual enters a field of study as a novice. The novice needs to learn the guiding principles and rules of a given task in order to perform that task. Concurrently; the novice needs to be exposed to specific cases, or instances, that test the boundaries of such principles. Generally, a novice will find a mentor to guide her through the process of acquiring new knowledge. A fairly simple example would be someone learning to play chess. The novice chess player seeks a mentor to teach her the object of the game, the number of spaces, the names of the pieces, the function of each piece, how each piece is moved, and the necessary conditions for winning or losing the game.In time, and with much practice, the novice begins to recognise patterns of behavior within cases and, thus, becomes a journeyman. With more practice and exposure to increasingly complex cases, the journeyman finds patterns not only within cases but also between cases. More importantly, the journeyman learns thak these patterns often repeat themselves over time. The journeyman still maintains regtdar contact with a mentor to solve specific problems and learn more complex strategies. Returning to the example of the chess player, the individual begins to learn patterns of opening moves, offensive and defensive game-playing strategies, and patterns of victory and defeat.When a journeyman starts to make and test hypotheses about future behavior based on past experiences, she begins the next transition. Once she creatively generates knowledge, rather than simply matching superficial patterns, she becomes an expert. At this point, she is confident in her knowledge and no longer needs a mentor as a guide—she becomes responsible for her own knowledge. In the chess example, once a journeyman begins competing against experts, makes predictions based on patterns, and tests those predictions against actual behavior, she is generating new knowledge and a deeper understanding of the game. She is creating her own cases rather than relying on the cases of others.The Power of ExpertiseAn expert perceives meaningful patterns in her domain better than non-experts. Where a novice perceives random or disconnected data points, an expert connects regular patterns雅思阅读真题:From A Novice to An Expert从新⼿到专家题⽬:。

首先基于改进的情景本体对情景中Agent所观察的实体进行“时一空”状态的获取和计算;其次,结合元认知环结构的语义推理算法对异常情景进行检测和评估,并反馈于Agent,最终做出符合当前情景下用户需求的动作或反应。
经过在智能家居环境中的实验验证,在原有几种具有代表性的机器学习处理方法基础上,所提方法在其决策精确性上平均提高10%以上,响应时间则增加5%左右,且实现了在应用领域上的拓展,增强了实用性。

ANNEX to Resolution No.303of July 2,2002“Regulation of limitation of exposure to electrical,magnetic and electromagnetic fields in the radio frequency range between 9KHz and 300GHz”.To ensure optimal radio performance and make sure human exposure to radio frequency electromagnetic energy is within the guidelines set forth in the above standards,always adhere to the following procedures.Portable Radio Operation and EME ExposureAntenna CareUse only the supplied or an approved replacement antenna.Unauthorized antennas,modifications,or attachments could damage the radio and may violate FCC regulations.Do NOT hold the antenna when the radio is “IN USE.”Holding the antenna affects the effective range.Body-Worn OperationTo maintain compliances with FCC/Health Canada RF exposureguidelines,if you wear a radio on your body when transmitting,always place the radio in a Motorola-supplied or approved clip,holder,holster,case or body harness for this e of non-Motorola-approved accessories may exceed FCC/Health Canada RF exposure guidelines.If you do not use one of the Motorola-supplied or approved body-worn accessories and are not using the radio held in the normal useposition,ensure the radio and its antenna are at least 1inch (2.5cm)from your body when transmitting.Data OperationIf applicable,when using any data feature of the radio with or without an accessory cable,position the radio and its antenna at least one inch (2.5cm)from the body .Approved AccessoriesFor a list of approved Motorola accessories,visit out Web site at .Electromagnetic Interference/CompatibilityNote:Nearly every electronic device is susceptible to electromagnetic interference (EMI)if inadequately shielded,designed or otherwise configured for electromagnetic compatibility.This device complies with Part 15of the FCC Rules.Operation is subject to the following two conditions:1.This device may not cause harmful interference;and 2.This device must accept any interference received,including interference that may cause undesired operation.FacilitiesTo avoid electromagnetic interference and/or compatibility conflicts,turn off your radio in any facility where posted notices instruct you to do so.Hospitals or health care facilities may be using equipment that is sensitive to external RF energy.AircraftWhen instructed to do so,turn off your radio when onboard on aircraft.Any use of a radio must be in accordance with applicable regulations per airline crew instructions.Medical Devices –PacemakersThe Advanced Medical Technology Association recommends that a minimum separation of 6inches (15cm)be maintained between a handheld wireless radio and a pacemaker.These recommendations are consistent with the independent research by andrecommendations of the U.S.Food and Drug Administration.People with pacemakers should:•ALWAYS keep the radio more than 6inches (15cm)from their pacemaker when the radio is turned ON.•Not carry the radio in the breast pocket.•Use the ear opposite the pacemaker to minimize the potential for interference.•Turn the radio OFF immediately if there is any reason to suspect that interference is taking place.Medical Devices –Hearing AidsSome digital wireless radios may interfere with some hearing aids.In the event of such interference,you may want to consult your hearing aid manufacturer to discuss alternatives.Medical Devices -OtherIf you use any other personal medical device,consult themanufacturer of your device to determine if it is adequately shielded from RF energy.Your physician may be able to assist you in obtaining this information.Safety and General Use While DrivingCheck the laws and regulations regarding the use of radios in the area where you drive,and always obey them.If you do use your radio while driving,please:•Give full attention to driving and to the road.•Use hands-free operation,if available.•Pull off the road and park before making or answering a call if driving conditions so require.The use of a two-way radio while engaged in activities requiringconcentration may cause distraction or otherwise impair your ability to safely participate in such activities.Always use technology safely.Do not place a portable radio in the area over an air bag or in the air bag deployment area.Air bags inflate with great force.If a portable radio is placed in the air bag deployment area and the air bag inflates,the radio may be propelled with great force and cause serious injury to occupants of the vehicle.Potentially Explosive AtmospheresTurn off your radio prior to entering any area with a potentially explosive atmosphere.Only radio types that are especially qualified should be used in such areas as “Intrinsically Safe.”Do not remove,install or charge batteries in such areas.Sparks in a potentially explosiveatmosphere can cause an explosion or fire resulting in bodily injury or even death.Note:The areas with potentially explosive atmospheres referred to above include fueling areas such as below decks on boats,fuel or chemical transfer or storage facilities,areas where the air contains chemicals or particles (such as grain,dust or metal powders)and any other area where you would normally be advised to turn off your vehicle engine.Areas with potentially explosive atmospheres are often—but not always—posted.Blasting Caps and AreasTo avoid possible interference with blasting operations,turn off your radio when you are near electrical blasting caps,in a blasting area,or in areas posted “Turn off two-way radios.”Obey all signs and instructions.Operational CautionsAntennasDo not use any portable radio that has a damaged antenna.If a damaged antenna comes into contact with your skin,a minor burn can result.BatteriesAll batteries can cause property damage and/or bodily injury such as burns if a conductive material—like jewelry,keys or beaded chains—touch exposed terminals.The conductive material may complete an electrical circuit (short circuit)and become quite hot.Exercise care in handling any charged battery,particularly when placing it inside a pocket,purse or other container with metal objects.Exercise care when removing NiMH or AAA batteries.Do not use sharp or conductive tools to remove either of these batteries.Battery Charger Safety Instructions:Save these Instructions1.Do not expose the charger to rain or snow.2.Do not operate or disassemble the charger if it has received a sharp blow,or has been dropped or damaged in any way.3.Never alter the AC cord or plug provided with the unit.If the plug will not fit the outlet,have the proper outlet installed by a qualified electrician.An improper condition can result in a risk of electric shock.4.To reduce the risk of damage to the cord or plug,pull the plug rather than the cord when disconnecting the charger from the AC receptacle.5.To reduce the risk of electric shock,unplug the charger from the outlet before attempting any maintenance or cleaning.e of an attachment not recommended or sold by Motorola may result in a risk of fire,electric shock or personal injury.7.Make sure the cord is located so it will not be stepped on,tripped over or subjected to damage or stress.8.An extension cord should not be used unless absolutely e of an improper extension cord could result in a risk of a fire and/or electric shock.If an extension cord must be used,make sure that:•The pins on the plug of the extension cord are the same number,size and shape as those on the plug of the charger.•The extension cord is properly wired and in good electrical condition.•The extension cord size is 18AWG for lengths up to 100feet,and 16AWG for lengths up to 150feet.9.The supply cord of the AC adaptor cannot be replaced.If the cord is damaged,call

O OVERVIEW: The RDFR ',5(&725V perform speed, direction and steering functions for R adio/C on-trolled vehicles powered by two independent electric motors employed as a right drive and a left drive.They’re used for robots with tank tread drives or separate drive wheels, and twin-screw boats or subs where maneuverablility is enhanced by differential props combined with rudder steering. They require two R/C channels, one to command throttle speed &direction and the other steering. Each RDFR unit has two rugged forward/reverse speed controls coupled to-gether through special logic that generates the differen-tial right and left motor rotation needed to guide the vehicle. When used with a spring centered joy stick:hands off is stopped, up stick gets straight ahead,and down yields backwards. Pure right or left twirls the vehicle as the motors turn opposite directions.In between stick positions are completely propor-tional, including reverse. Other modes of operation are available. RDFR ',5(&725V are compatible with most model R/C systems, including Futaba.These instructions are for the RDFR21 through RDFR23.PLEASE read and understand them before connecting power. The RDFR32 through RDFR61E have a separate instruction manual.VERI FY MODEL SELECTION: On page 2 theSPEC CHART shows ratings for one single motor output.Measure your motor’s continuous running current under actual normal mechanical load. OR use the SELECTOR CHART on this page. Begin by determining your DC PM motors armature terminal resistance by consulting specifications or measurement. Armature resistance cannot be measured with a normal ohm meter. Instead,take the measurement by mechanically locking the mo-tor shaft and reading the current drawn while briefly powered from a fresh alkaline 1.5 volt "D" cell. The SELECTOR CHART on this page shows armature resis-tance in "D" cell amps or specified ohms. At your operating voltage the RDFR model choosen should list lower Ohms or higher Amps than your motor. VAN-TEC surge ratings express usable motor starting surge current over a realistic 5 second period.JUMPERS: The Jumpers are factory set for the mostpopular single joystick mixed tank type steering mode so this section may be skipped for anxious users. These settings are noted by the shaded sections in the jumper tables. Otherwise begin setting the programming jumpers for the functions that suite your application. Jumper ON= installed=present=closed.DUAL I NPUT MODES: These modes use both R/C S ervo C ommand P ulse inputs.MIXED FOR T ANK STEERING: Five algorithms are jumper selectable: LINEAR , mild EXPO nential 1, moderate EX-PO nential 2, S KIP & optional VA R iable ratio. The EXPO nential modes spread the steering to provide agently increasing steering function for very precise neutral steering.VANTEC RDFR2nR/C D U AL F ORW ARD & R EVERSESPEED CONTROL - Mix ed SteeringHELP: (800) 882-6832MODELS RDFR21 - RDFR23ROBOTS, TWINSCREW BOA TS INST ALLA TION & WIRING JUMPER SELECTIONS MOUNTINGMANUAL90.17 7RDFR2190.12 9RDFR22 90.13 8.3RDFR32 90.08 15RDFR33 120.23 5.3RDFR21 120.16 7RDFR22 120.17 6.6RDFR32 120.11 9.5RDFR33 120.07 NA RDFR36E 120.05 NA RDFR38E 180.34 3.7RDFR21 180.24 5.2RDFR22 180.25 4.7RDFR32 180.17 7RDFR33 180.12 9RDFR36E180.08 NA RDFR38E 240.46 2.9RDFR21 240.32 4RDFR22 240.34 3.7RDFR32 240.21 5.5RDFR33 240.15 7.2RDFR36E 240.10 9.6RDFR38E 360.52 2.5RDFR32 360.33 3.8RDFR33 360.24 5.2RDFR36E 480.73 1.8RDFR42 480.53 2.5RDFR43E 600.92 1.4RDFR42 600.66 2RDFR43E 140 3.40 .4RDFR61SELECTOR CHARTV Ohm "D "Amp Part # V Ohm "D"Amp Part #The SKI P algorithm is for boats with rudders. It mixes steering into the speed commands only near the extremes of rudder steering. This gives maximum speed and stable roll forces and still offers maneu-verability. Especially for subs. A Y -connector splits the steering command to the RDFR and the rudder servo.The optional V AR iable ratio adjusts the steering gain according to the speed command. At slow speeds steer-ing gain and effectiveness is maximum. At full speed the steering gain is reduced. This places the less stable high speed turns beyond operator reach for safety .Gain selection: most users prefer HI gain to get the maxi-mum possible speed with the stick straight up; when the vehicle turns at full speed the wheel on the inside slows down but the outside wheel can’t go any faster because it’s already at top speed. Gain calibration is based upon a Futaba FP-8UAP with 100% A TV , 100% Dual Rate, no trim, centered at 1.53 ms, and factory defaults. This works well with other popular radios. Adjustment of gain may also be made at the transmitter using the A TV servo travel adjustment potentiometer. The Notch defines the starting duty cycle so your motor isn’t driven with a non-rotating but power wasting duty cycle. Deadband is the joystick movement around center that produces no action; it makes "off" easy to find.NON-MIXED DUAL INPUT: The mixing function may bedefeated to realize two independent speed controls with two independent Servo Command Pulse inputs.This enables you to control your vehicle with a separate joystick for each motor and do the turning algorithm with your thumbs. SCP Input S =Motor #1,SCP input T =Motor #2. To implement: install jumper JP2. The RDFR is the only controller that gives you your choice. Note this configuration may have matching curve pairs or different algorithms for each output.The factory CUSTOM option allows you to optimize mixing/ non-mixing, gain, deadband and failsafe values.The PWM chopping frequency is the rec-ommended 338 Hz(default) or install jumper JP1 to select 21.6 KHz . TheRDFR s operate optimally in a radio envi-ronment at 338 HZ. At 21.6 KHz more RFI is gener-ated which requires additional RFI filters and the amper-age must be derated to 30%.BRAKING AND REVERSING: the optically iso-lated outputs are P ulse W idth M odulated full H-bridge circuits. For speed control the bottom half of the bridge is modulated while the diagonal upper bridge leg is held on. Sequenced electro-dy-namic braking shunts the motor by modulating both top legs of the bridge. With a command to "stop" the brake is gently ramped from 0 to 100%duty cycle. When an R/C command changes direc-tion the brake is quickly sequenced to first bring the motor to a halt, then the reversing PWM power is acccelerated up to the commanded speed. This forced sequencing minimizes motor "plugging"and stress on your mechanical components.JumpersJP3 and JP4 select the appropriate ramp-ing for your application.SPEC CHARTSingle Output Part Voltage Con’t | Start’g TypLossApproximate Wgt Wire CommentsNumberRange AmpsLegOhmsSize w/ connector Oz.AWGFor 4 cell to 24VDC systems:RDFR21 4.5-3014 45.009 4.2 X 2.9 X 1.3"718Lowest CostRDFR22 4.5-3020 60.005 4.2 X 2.9 X 1.3"916Most compact unit, withRDFR23 4.5-3030 60.004 4.2 X 2.9 X 1.3"916 popular algorithms For 12-36VDC systems:RDFR339-4335 95.006 6.25 X 2.2 X 4" 2712Most popular!RDFR36E 9-4360160.004 6.25 X 2.3 X 4.5"3910Used in Bomb Disposal Robots RDFR38E 9-3280220.002 6.25 X 2.3 X 4.5"43 8Drives 3 HP Acrobatic Go-Cart For 42-48VDC systens:RDFR4232-6020 54.013 6.25 X 2.3 X 4"2718Medium voltage systems RDFR43E 32-603595.0136.25 X 2.3 X 4.5"3939 Extruded caseFor 60-120 VDC systems (Units below require filtered +12-36 VDC @ 180ma)RDFR6150-14010 27.03 6.25 X 2.2 X 4"2718Grainger’s Dayton or Minarik RDFR61E 50-14015 40.03 6.25 X 2.3 X 4.5"3916 90 VDC Gearhead motorsSKIPEXPO2LINEAREXPO121.6338JP1JP1ON OFFWIRING: Follow the layout schematic. Do not power the RDFR from batteries under charge, bat-tery eliminators or chargers without consulting fac-tory.POWER & MOTOR : Observe battery polarity.The SPEC CHART shows the minimum size wire for battery power and motor wiring. The RDFR21-23’s have two screw connections for each node to assure solid high current connections for the handy plug-in terminal block. Run double wires, one from each screw connection for a node, to the respective motor terminal or fuse. Run 4 wires from the 4 screws for the GROUND node; the ground supports the current for both motors. Wire with the minimum length wire practical and keep this wiring separated from the R/C receiver and SCP ulse cables. Ground your chassis at a single point but don’t use the chassis to conduct current. Use separate regular-blow fuses to feed the +1 and +2 power terminals; select the smallest fuse which will support normal operation.A MOV should be installed directly across the motor brushes and a .001 ufd ceramic disc capacitor directly across each motors brushes and between each brush and their motor case for RFI protection.SERVO COMMAND PULSE: The inputs plug into your receiver like a servo and the connectors are engraved: Steering = S , and Throttle = T . Only the receiver common and your S ervo C ommand P ulse signal wires are required to drive the optical isolators within the RDFR. Some R/C receivers don’t have adequate SCP ulse drive for Y-connecting the RDFR with the rudder servo without a "peanut" amplifier;contact the factory for this easy solution if a direct Y fails to work. The RDFR neither takes power from nor supplies power to the R/C receiver; thus the plus (red) wire is not used. Available with Futaba J or G,Airtronics, Deans, or JR connectors, it works with FM or PCM radios. Use the full length supplied R/C antenna and locate it away from other wires and metal structures.OPTIONAL BR AKE R ELEASE or CLUTCH ENGAGEMENT: provides a 2 Amp output current sink that turns on when there’s an R/C "motion" command. With a "stop" R/C command it goes off after a short delay. Connect at the single terminal block connection BRK .

Simultaneous operation of both halves at maximum ratings may require cooling air or mounting the RDFR side-opposite-the-terminal-block to additional heat sinking. Usually the metal frame of your vehicle is sufficient. No special heatsinks are required. While mounting remove the cover to monitor the mounting screw length; screws should not thread into the case more than 1/8".OPERATION: If the RDFR becomes too hot to hold cease operation and investigate the cause. In the popular tank steering mixed mode both servo connectors must be plugged in for the unit to operate even one motor. Use transmitter trims of both channels to set motors off deadband. Assignment of right/left motors to #1 or #2 outputs, motor(s) polarity, and transmitter servo reversing switches have numerous combinations;select the correct combination experimently but NEVER reverse the motor battery polarity. Noise in sound systems is due to a poor power distribution scheme; ask for our application note on AF noise. Output current through the MOSFET ransistors is compression limited above a threshhold by PWMduty cycle limiting. The threshhold adjust-ment trimpot for each output is factory set. CW rotation increases the limiter thresh-hold.The RDFR comes with a limited one year warranty based upon a fixed repair charge for units not tampered with or abused. These products are not safety devices nor for use in life-critical or life-support systems. For single channel controllers with these features see our RSFR spec sheet.

《Meta分析系列之六_间接比较及网状分析》篇一Meta分析系列之六_间接比较及网状分析Meta分析系列之六:间接比较及网状分析一、引言随着科研领域的快速发展,传统的前瞻性实验已经难以满足越来越多的科研需求。
于是,通过文献检索和汇总信息进行的Meta分析成为重要的辅助手段。
Meta分析中除了直接的同质实验结果对比,还有一种常见的策略,即间接比较和网状分析。
本文旨在介绍如何高质量地进行间接比较及网状分析。
二、方法论1. 间接比较间接比较是通过综合多个独立研究的多个变量来估计研究效应,通过将各个研究的直接效应进行比较和转换,再进一步比较间接效应。
这种方法的优点在于可以扩展到复杂的研究设计,并可以整合那些无法直接比较的异质性研究。
2. 网状分析网状分析是一种综合多种不同类型证据的统计方法,用于评估不同干预措施的相对效果。
它通过构建一个复杂的网络图来展示不同研究之间的相互关系,并使用贝叶斯模型或多元回归模型等统计方法进行综合分析。
三、间接比较与网状分析的应用本文以一个药物研究的Meta分析为例,通过将多篇药物干预的研究成果进行整合和对比,评估其效果。
我们采用间接比较和网状分析的方法,对不同药物干预的疗效进行综合评估。
首先,我们收集了多篇关于该药物研究的文献,并对这些文献进行了筛选和评估。
然后,我们使用间接比较的方法,对不同研究中的药物剂量、药物作用机制、研究人群等因素进行综合比较,得出各研究的直接效应。
接下来,我们利用这些直接效应构建了一个复杂的网络图,进行网状分析。
在网状分析中,我们采用了贝叶斯模型来评估不同药物干预之间的相对效果。
四、结果与讨论通过综合分析和比较各研究的直接效应,我们得出了各种药物干预的相对效果排序。
在网状分析中,我们发现某些药物在特定情况下具有较好的疗效,而其他药物在另一些情况下可能更有效。
此外,我们还发现某些因素(如药物剂量、研究人群等)对药物疗效的影响较大。
这些结果为临床实践提供了重要的参考依据。

医学研究领域德尔菲法实施和报告标准(CREDES)解读德尔菲法(Delphi method)是一种通过专家意见的循环反馈达成共识的技术。
在医学研究领域,德尔菲法被广泛应用于需预测或评估的问题中,包括治疗方案、患者管理、疾病诊断等方面。
为了提高德尔菲法的可信度和规范操作,医学界提出了德尔菲法实施和报告标准(CREDES,Consensus on Reporting of Delphi studies)。
CREDES标准是由一群国际医学专家共同制定的,旨在规范德尔菲法研究的设计、实施和报告过程,以确保研究的科学性和可靠性。
该标准分为六个主要方面:问题提出与定义、专家选择、循环次数、专家反馈、数据汇总与分析、报告规范。
首先,在问题提出与定义方面,研究者需要明确问题的目标和范围,并根据需要制定问卷。
问题的设计应尽量避免模糊性,以确保专家能够准确理解并给出可行的建议。
其次,专家选择也是德尔菲法研究不可忽视的一环。
研究者应该选择那些在相关领域专业知识丰富、经验丰富的专家参与研究。
专家的选择应该经过审核和确认,以确保其具备相应的背景知识和能力。
循环次数是德尔菲法中的重要环节之一。
根据CREDES标准,循环次数应提前规定,并在开始研究之前明确告知专家们。
循环次数的设置应综合考虑问题的复杂性和专家的时间及精力。
专家反馈是德尔菲法中的核心环节,也是达成共识的关键。
根据CREDES标准,研究者应该向每位专家提供其他专家的匿名意见,以避免个人偏见的影响。
专家在反馈时应准确、全面地回答问题,并根据需要提供证据支持。
在数据汇总与分析阶段,研究者应将专家反馈结果进行统计和汇总。
通常会使用一些定量方法,如平均值、中位数、百分比等来描述专家意见的一致性和差异性。
最后,根据CREDES标准,研究者在报告研究结果时应提供透明、详尽的信息,包括研究的目的、方法、参与专家的人数和背景、循环次数、专家反馈结果、数据汇总和分析等。
这有助于其他研究者评估研究的可信度和应用性。

我们的研究使用了世界各地许多研究人员发布的可公开获得的数据(由MRC-IEU OpenGW AS数据库整理),并真正证明了开放数据共享在实现健康研究中的新发现方面的潜力。
我们已经证明,对现有数据的这种重复利用为降低药物开发成本提供了一种有效的方法,并有望为健康和社会带来好处。
However, some limitations do exist. When the user searches the RDFDB, some of the results are listed as the index of the resource and the user has to take further actions (click each of listed result items) to find more detailed information. There are also problems related to updating data. For example, when new data has been inserted in the original database, it cannot be reflected in the integrated system immediately.
For our RDF system there are two limitations existing that are not due to the RDF model but due to RDFDB itself. (1) RDFDB does not support the RDF Schema which, therefore, makes the ontology described in the Schema irrelevant and (2) RDFDB does not support part matching, so it is impossible to search in the following way: “find all the publications whose title include the word ‘visualization’”. This is limiting our ability to build practical systems.
As an increasing number of relational databases are put on the web, there is an urgent need to integrate all these operational databases. The most important practical use of the Semantic Web is to make the system understand the implicit relationships between these databases and integrate them through the semantic layer. As a result, the databases become semantically linked rather than syntactically linked which could be done in a relational database system.
More research needs to be done to support the use of the Semantic Web: firstly on the interoperability between the different schemas; secondly on how to make the links between the concepts and the terms. We also expect more powerful searching tools for RDF data and schema. The conference will enable us to learn about advances in the Semantic Web technologies and apply them to our expertise matcher and then transfer the learning to Symularity Ltd for commercial exploitation.
