Software Configuration Management (SCM) is a concept of trying to group the changing artifacts of software development to try to manage the complexity of modern day software. This paper provides a roadmap for improving the SCM support process based on a meta-model. I developed a model that defines key practice...
The Sacagawea testbed has been designed to support testing and development of decision making models, and associated uncertainty management techniques, that are appropriate under real-time problem solving constraints. Conceptually, it provides a simulated temporal and spatial environment, the latter consisting of a terrain grid of elevation and tree cover data,...
Watering a lawn involves several factors such as laying out the sprinklers and valves, trenching, laying pipes, cables, etc. The primary goal is to ensure uniform watering subject to various constraints. We present some abstract problems involving sprinkler layout and some solutions with theoretical worst case bounds on their performance....
This project aims at building a Java application and a Java applet that would simulate a Stern-Gerlach laboratory in Quantum Mechanics. The project provides a tool for allowing the student to quickly design and run on the computer screen a number of experiments involving spin systems. This application could be...
Spreadsheet languages are widely used by end users for many different purposes. Previous research shows that spreadsheets often contain faults. To help end users test their spreadsheets, in previous research, a testing methodology for spreadsheets has been developed. Th.is methodology is supported by an automatic test case generation (ATCG) methodology....
This report describes "VIGRAM" (Visual Programming) which is a program understanding and complexity metric analysis tool for Pascal programs. VIGRAM is implemented on the Macintosh as one part of the "O.S.U." (Qregon Speedcode Universe) project. With VIGRAM, the source code of a Pascal procedure can be displayed as a visual...
Performance of a reliable storage subsystem for a centralized database system was studied by simulation. The reliable storage subsystem studied consists of three redundant disk units that are updated one at a time from a consistent database state to another consistent database state, Thus, even if a central processor and/or...
The demand for improved controllers creates the need for synthesis techniques which emphasize optimality. Optimality automatically infers stability. This thesis presents one such technique which is not limited to linear systems. The theory of dynamic programming is applied to the synthesis of optimal controllers with emphasis on missile flight control...
Wireless technologies advance rapidly in the recent time. The maJor initiative is the realization of the third generation wireless network that provides high bandwidth access to digital data on the Internet. Moreover, recent improvements in computer and embedded systems have enabled portable devices with sufficiently high computing capability.
The combination...
