This thesis addresses the problem of how to determine the optimum level of mesh discretization required to solve a magnetic device accurately and efficiently using finite elements. Currently, most finite element packages require user intervention to assure that the mesh…

Passively accepting measurements of the world is not enough, as the data obtained is always incomplete, and the inferences made from it uncertain to a degree which is often unacceptable. Machines that operate autonomously will always be faced with this…

Wireless digital data system designers have formidable future design challenges in order to provide the mobile user with a quality of service comparable to that of a wireline system in such metrics as responsiveness, quality, and throughput. The goal of…

In the context of teleoperated mobile robotics, the use of video data is one of the most desirable sensing modalities for vehicle guidance. Unfortunately, maintaining reliable noise-free video transmission, especially in cost sensitive teleoperation applications is a frequent problem., We…

This thesis considers an object-oriented approach to dimensional analysis for engineering design. A dimensional analysis system is developed which can be applied to the knowledge-based engineering design especially of electromagnetic devices. All the system is coded in C++. A shell…

This thesis describes an algorithm for detecting moving objects in images taken from a moving robot. The algorithm distinguishes itself from other similar, existing solutions in that it lends itself to a fast implementation, yet provides results which are reliable…
