Recent developments in CAD for electromagnetic devices have utilized knowledge-based programming techniques to simplify the task of design process automation. The ultimate goal is to duplicate the role an expert designer performs in synthesizing devices such as transformers, motors, and…

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…

A design for a unified model based on the hypermedia paradigm is proposed as a means to a better synergism of the functionalities of different knowledge manipulation tools. A survey of past and present hypermdia systems has been achieved, and…

The complete design of many electromagnetic devices requires the solution of a coupled problem. Typically, the coupling is in the form of magnetic/thermal, magnetic/structural, magnetic/electronic, or possibly a combination of several disciplines. Computer based tools exist for many of these…

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 proposes a speaker-independent, continuous-speech stop recognition algorithm. The method incorporates knowledge into the system by means of rules whose conditions are linked to acoustic events. Coarticulatory effects present in the speech are taken into account with the analysis…

Autonomous robotic operation in an unstructured or partially known environment requires sensing and sensor-based control. To overcome the problems with current "eye-in-hand" systems, miniature amplitude-based, infra-red proximity sensors are being studied. Obtaining position and velocity estimates of a rigid body…

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…
