Responder tracking application

Creator:: Wanalertlak, Naroot
Abstract:: We have developed a prototype web-based GIS application for tracking the locations of moving entities. This application, which is called the Responder application, consists of two parts: the Responder client and the Responder server. The Responder client is a .NET application written in C#. It reads the location data from...

Atomic Bifurcations of Degenerate Curves in 3D Linear Symmetric Tensor Fields

Creator:: Hongyu, Nie
Abstract:: Tensor field topology is of importance to research areas of medicine, science, and engineering. Degenerate curves are one of the crucial topological features that provide valuable insights for tensor field visualization. In this thesis, we study the atomic bifurcations of degenerate curves in 3D linear second-order symmetric tensor fields, and...

Inequality reasoning

Creator:: Leixuan, Yang
Abstract:: One of the tasks of inequality reasoning is to determine the relationship between two quantities for any given set of qualitative constraints. For implementation of this kind of reasoning, Simmons [1] has provided a technique called the "graph search" (GS). This paper briefly reviews GS technique, then presents an implementation...

Recursive construction for error correcting constant weight codes

Creator:: Ramanathan, Gowri
Abstract:: In this project we have designed a new construction method for t error correcting constant weight codes. This method is an improvement over the existing codes in terms of information rate. The construction method is recursive as it is based on the observation that 2t error correcting code can be...

PlanView & HViews : graphical user interfaces for viewing plan data

Creator:: Tabayoyon, Al
Abstract:: Visualizing and navigating through a plan is difficult without graphics. Two X applications, PlanView and HViews, are graphical user interfaces to an AI planner, OPIE, developed at the University of Oregon. In addition to a plan generator, OPIE includes a facility to generate operator abstractions which in turn are used...

An experiment in user-centered development

Creator:: Ritter, Paul R.
Abstract:: This paper describes the results of a research project to design new graphical user interlace to an existing applications software product, using the techniques of user-centered design. The project began with a literature review to determine the currently accepted methodology in the area of user-centered design, with emphasis on the...

Experdite : a model based expert diagnostic system using a high level test description language

Creator:: Tilp, Philip
Abstract:: To be competitive in the development and production of complex electronic systems, a company must constantly scrutinize its manufacturing processes to find ways to reduce costs and increase productivity. One of the more costly problems is the inability to troubleshoot and repair faulty circuit boards on the spot. Rather, they...

An editor for message passing programs

Creator:: Pai, Akash L.
Abstract:: Preparing code for parallelization is one of the most time consuming programming tasks; approximately 24% of the program development activity is spend in this phase. In message passing systems, this is usually achieved by the addition of run-time message-passing library calls. The primitives provided by different message-passing libraries are similar,...

Lightweight Corefile Browser

Creator:: Muddarangegowda, Manjunath
Abstract:: One of the main problems in debugging parallel programs is in determining how far a parallel program has executed when it crashes or stops. Even if the program dumps core files for all the parallel processes, the information is at such a low level that it is difficult to interpret...
