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…

The ability to suggest a means of solving a novel problem through the remembering and recalling of previous experiences is a tenet of the Case-based reasoning (CBR) paradigm. This approach is well suited for the engineering design domain since an…

The Finite Element and Finite Difference methods are both widely used in estimating magnetic field solutions. Both methods are based on refining an initial estimate oft a solution using an iterative process; unfortunately, this rarely contains knowledge of the most…

New digital communication applications, such as multimedia, require very powerful error correcting codes that deliver low error rates while operating at low to moderate ratios (SNRs). Turbo codes have reasonable complexity and can achieve very low error rates if a…

A knowledge-based expert system was developed to assess the level of abnormality in the brain electrical activity of pediatric patients monitored in the intensive care unit. Six hours of an 8-channel EEG record serves as the input to the monitoring…

The objective of this thesis is to provide an analysis of Linear Predictive Coding (LPC) frequencies and Line Spectrum Pair (LSP) frequencies. While it is generally known that LSP frequencies congregate about LPC formants, this study will deal with how…

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…

In Radio Detection and Ranging, the inverse problem is that of acquiring knowledge of the physical features of a body by making observations of the reflected energy and synthesising the model from the measured data. This procedure is in contrast…

In this thesis, a problem of optimal control for a CTMP(chemi-thermo-mechanical pulping) process is formulated and solved by applying simulated annealing algorithm., Based on priori knowledge accumulated from years of practical operations, a set of imprecise and empirical equations are…
