This thesis presents a development environment for Design Expert Systems that features a new language where the roles of knowledge and the way it is brought to bear are predefined by the solution method., The language also allows knowledge to…

Over the past few years, the amount of electronic information available from the Internet has increased dramatically. Unfortunately, the search tools currently available for retrieving and filtering such information remain inadequate in balancing relevance and comprehensiveness. This work proposes a…

This thesis considers the dimensional analysis theory in engineering. A Knowledge-Aided Design Tool is presented which permits the solution of many aspects of Dimensional Analysis for electromagnetics. The KAD Tool was coded in the language Lisp with Allegro Common Lisp…

The purpose of this thesis is to evaluate the medical data management expert system at the Pediatric Intensive Care Unit of the Montreal Children's Hospital. The objective of this study is to provide a systematic method to evaluate and, progressively…

The present thesis is concerned with the development of an expert system for the preliminary design of point-to-point HVDC transmission systems, TRANSEPT-DC. This expert system module complements other expert system modules concerned with AC design, insulation coordination, and reliability, all…

In this thesis, the concept of an intelligent system for the design and planning of electric power systems is developed. Such a system serves to preserve the vast body of power system design knowledge by identifying, structuring and consolidating it…

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 performance of mineral grinding circuits strongly affects downstream processes such as flotation and cyanidation, and grinding is often the single most expensive unit operation. Hence, optimization efforts must be made on a regular basis to maintain and improve its…

This thesis explores the use of randomized, performance-based search strategies to improve the generalization of an automatic speech recognition system based on hidden Markov models. We apply simulated annealing and random search to several components of the system, including phoneme…

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…
