Thesis (M. Tech.) -- Central University of Technology, Free State, 2007 / With technology advancing, more and more people turn to the World Wide Web to conduct business. This may include buying and selling on the Web, advertising and monitoring of business activities. There is a big need for software and systems that enable remote monitoring and controlling of business activities. The Mechatronics Research Group of the Faculty of Engineering, Information and Communication Technology at the Central University of Technology, Free State, has identified a similar need. This research group has created an Automated Manufacturing System around which research topics revolve. They want to monitor this Automated Manufacturing System from remote locations like their offices or, if possible, from home. The Remote Information Management (RIM) System was developed, using the Rapid Application Development (RAD) Methodology. The reasons why this methodology was used, is because it is the best to use in a changing environment, when the system needs to be developed very quickly and when most of the data is already available. This is a good description of the Automated Manufacturing System’s environment. The RAD methodology consists of four stages: Requirements Planning, User Design, Rapid Construction and Transition. Project Management is used throughout these stages to ensure that the project goes according to plan. Development of the RIM system went through all four stages and project management was applied. The final system consisted of a Web Page with Web Camera views of the Automated Manufacturing System. The application that was developed using National Instruments LabVIEW, Microsoft Visual C++, and Microsoft Excel, is embedded in this Web Page. This application is called a Virtual Instrument (VI). The VI shows real-time data from the Automated Manufacturing System. Control over the VI can be granted and will allow the remote user to create reports on how many different products was produced and system downtimes. A system like the RIM System has advantages in the business world. It can enable telecommuting and will allow employees and managers to monitor (and even control) manufacturing systems, or any system connected to a PLC, from remote locations.

This study reports changes in online database searching at North Texas State University when equipment speed was increased. Data were from database vendor invoices and price and sale data of online equipment. The hypotheses examined the relationship between the decrease in the cost of online equipment and the change to faster online equipment and the change in the number of databases that changed for online types. The change in equipment was related to changes in the number of offline prints per hour, the average time per search, the average number of descriptors per search, the number of searches per month, and the rank order of database use over the studied period. The increase in the number of databases with billed types was related to the number of online billed types produced. The number of prints was related to the number of billed types. Time spent online was examined for annual seasonal cycles. The major statistical tool was time-series analysis, although other methods were applied.

D.Litt. et Phil. (Information Science) / The project involved the design of a multimedia study package for distance teaching in computerised information retrieval. This included external online and CD-ROM informa- tion retrieval, as well as specialized systems such as in-house databases, videotex, teletext and Internet. The target group was information specialists. The findings may also apply to other target groups, provided a thorough situation analysis serves as point of departure. The project was initiated by the growing importance of distance education, the constant developments in the online industry and the need for didactically grounded study packages for teaching computerised information retrieval skills. Such packages should focus on technological knowledge and skills on the higher cognitive, affective and psychomotor levels. A literature study was conducted on four subproblems: the nature of distance education; the characteristics of multimedia study packages; the didactical grounding of such packages (including curriculum development, instructional design and media selection); and the state of the art regarding the 'teaching of computerised information retrieval. This led to the conclusion that the theory of distance education should serve as focal point in the design of a multimedia package, while special attention is also given to Keegan's theory which focuses on the reintegration of the teaching and learning acts. Study packages should be the result of instructional design, which is dependent on curriculum development. The latter includes decisions made on the macro and meso levels of the curriculum and the consideration of technological infrastructures available in the wider society. Provision should also be made for the typical characteristics of multimedia packages for distance teaching, including individual study, irregular contact teaching sessions, active student involvement, opportunities for self-evaluation, enriching and remedial learning events, student support and the recognition of the needs of adult learners (andragogical needs), as well as those of young adults. The mastering of higher order skills should be supported by opportunities for active student involvement including self-evaluation of lower order skills. Provision should also be made 1I1 for the practical application of knowledge and skills, as welI as evaluation skills, by fully exploiting the possibilities offered by interactive teaching. Students should, however, attend interactive sessions welI prepared. This could be ensured by making use of prior self- evaluation as well as tutor evaluation of both subject matter and media literacy. A variety of media and teaching methods can be applied in the mediated teaching of computerised information retrieval. Media selection should be based on media character- istics, performance objectives, subject nature and logistical factors. An eclectic model for instructional design is proposed. A concept design for a multimedia package for distance teaching of computerised information retrieval was developed by applying this eclectic model. The concept design was based on the didactical situation at the University of South Africa. Although the design has focused on the ideal situation, where students have access to computers and attend sporadic contact teaching sessions, suggestions are also made for a differentiated package. These suggestions include a basic study package, a learning contract with the student and his employee, and a package with enriched learning experience.

A dissertation submitted to the Faculty of Science, University of the Witwatersrand, Johannesburg, in partial fulfillment of the requirements for the degree of Master of Science. Pretoria 1991. / Remote sensing can be used to produce maps of land-cover, but to be of use to the GIS community these maps must first be vectorized in an intelligent manner. Existing algorithms suffer from the defects of being slow, memory intensive and producing vast quantities of very short vectors. Furthermore if these vectors are thinned via standard algorithms, errors are introduced. The process of vectorizing raster maps is subject to major ambiguities. Thus an infinite family of vector maps ccrresponds to each raster map. This dissertation presents an algorithm for converting raster maps in a rapid manner to accurate vector maps with a minimum of vectors. The algorithm converts raster maps to vector maps using local information only, (a two by two neighbourhood). the method is "exact" in the sense that rasterizing the resulting polygons would produce exactly the same raster map, pixel for pixel. The method is "near optimal" in that it produces, in a local sense, that "exacb" vector map having the least number of vectors. The program is built around a home-grown object oriented Programming System (OOPS) for the C programming language. The main features of the OOPS system, (called OopCdaisy), are virtual and static methods, polymorphism, generalized containers, container indices and thorough error checking, The following general purpose objects are implemented with a large number of sophistiated methods :- Stacks, LIFO lists, scannable containers with indices, trees and 2D objects like points, lines etc. / AC2017

In order to improve the quality of care, there is urgent need to involve patients in their own healthcare. So to make patient centered health care system Personal Health Records are proposed as viable solution. This research discusses the importance of a Patient Centric Health Record system. Such systems can empower patients to participate in improving health care quality. It would also provide an economically viable solution to the need for better healthcare without escalating costs by avoiding duplication. The proposed system is Web-based; therefore it has high accessibility and availability. The cloud computing based architecture is used which will allow consumers to address the challenge of sharing medical data. PHR would provide a complete and accurate summary of the health and medical history of an individual by gathering data from many sources. This would make information accessible online to anyone who has the necessary electronic credentials to view the information. / by Vishesh Ved. / Thesis (M.S.C.S.)--Florida Atlantic University, 2010. / Includes bibliography. / Electronic reproduction.
