Testing Technical Feasibility in CPS Development Projects
Cyber-physical systems (CPSs) are service systems that connect a product’s physical and computational elements through telecommunication networks. Typically, the processes in CPSs are executed on this physical and computational infrastructure. As the developing of new CPS is costly, testing and validating a CPS’s design at an early stage of development is desirable to avoid bad investments. The high development and potentially high hardware costs, however, make it difficult to create a full CPS prototype only for testing. This work uses Trkman’s critical success factors of business process management (BPM) as a theoretical lens and identifies “technical-feasibility fit” as an additional complementary success factor. Based on these factors, we develop a method for creating CPS testbeds that allow testing of CPSs at lower costs at an early stage of the development. We demonstrate the method’s application by a case in which we develop a testbed for an electric vehicle charging service
Mariner IV Mission to Mars. Part I
This technical report is a series of individual papers documenting the Mariner-Mars project from its beginning in 1962 following the successful Mariner-Venus mission. Part I is pre-encounter data. It includes papers on the design, development, and testing of Mariner IV, as well as papers detailing methods of maintaining communication with and obtaining data from the spacecraft during flight, and expected results during encounter with Mars. Part 11, post-encounter data, to be published later, will consist of documentation of the events taking place during Mariner IV's encounter with Mars and thereafter. The Mariner-Mars mission, the culmination of an era of spacecraft development, has contributed much new technology to be used in future projects
Technology transfer: Transportation
Standard Research Institute (SRI) has operated a NASA-sponsored team for four years. The SRI Team is concentrating on solving problems in the public transportation area and on developing methods for decreasing the time gap between the development and the marketing of new technology and for aiding the movement of knowledge across industrial, disciplinary, and regional boundaries. The SRI TAT has developed a methodology that includes adaptive engineering of the aerospace technology and commercialization when a market is indicated. The SRI Team has handled highway problems on a regional rather than a state basis, because many states in similar climatic or geologic regions have similar problems. Program exposure has been increased to encompass almost all of the fifty states
The Colorado experience (evaluation and selection of hardware for automated, geo-based information systems)
A turnkey system which gives technical assistance to legislative redistricting and state census data affiliate activities is described. The procedures followed for the acquisition of the Colorado automated census mapping system are presented. Price and performance criteria of the system were examined and the system architecture is outlined
The private sector and family planning in developing countries
While a private sector exists in every society, the nature of its involvement in family planning service delivery varies widely across countries. This paper reviews the role of the private sector in family planning and discusses how much more of the demand for contraception can be met through the private sector, thereby reducing government's subsidies for contraception. Following the introduction, section 2 discusses the characteristics of private sector supply, with a strong emphasis on for-profit producers and distributors of contraceptives. Section 3 describes the distribution of users across sources and addresses the issue of pricing at public, for-profit and NGO sources of family planning services. In section 4 the experience to date with private sector approaches is outlined to provide a sense of what has been and is currently going on in public and and donor efforts to harness and collaborate with the private sector. Section 5 presents alternative means for government and donors to promote private sector activity in family planning, and suggests some of the costs of a greater private sector role. The final section summarizes and concludes the paper.Health Monitoring&Evaluation,Adolescent Health,Agricultural Knowledge&Information Systems,Health Economics&Finance,ICT Policy and Strategies
Technological Literacy Programs in Elementary School
Technology and engineering design education is offered as an elective in most secondary school curriculums, however a primary school curriculum is not common. The Standards for Technological Literacy (ITEEA, 2007), which focus on technological literacy and engineering design, are not typically included in primary education.
The objectives of this study are to determine if teachers and administrators think technology and engineering education provide new opportunities for elementary students, how they feel about technology and engineering education, and what obstacles exist for successful implementation. A literature review provided the background on federal, state, and local technology initiatives that exist for Virginia public schools. It also defined technology standards that exist and how they have been incorporated in state curriculum requirements at the elementary level.
A survey was used for both teachers and administrators at each elementary school in the sample. Data was collected from seventy-seven participants from twenty-four elementary schools. The results indicate ninety-two percent of respondents agree that implementation of a technology and engineering design education program would provide new educational opportunities at their schools. Eighty-seven percent of respondents feel it is essential to learn about technology and engineering design in elementary school.
Participants felt that students do use different types of technology in the classroom for finding information. But do not use technology and the engineering design process to troubleshoot and find solutions to problems through facilitated projects. Only a quarter of respondents were satisfied about the current technology and engineering educational opportunities at their schools.
Teachers and administrators indicated that the biggest obstacle that exists for successful implementation of a technology and engineering education curriculum is lack of funding, followed by a lack of materials
Technology transfer-transportation
Problems in the public transportation industry and refining methods for decreasing the time gap between the development and the marketing of new technology are considered. Eight NASA innovations are either being adapted for use on highways, railways, or rapid transit, or are already entering the marketplace. Chronologies for three of these programs are provided
