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…

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…

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…

This thesis studies the introduction of a priori structure into the design of learning systems based on artificial neural networks applied to sequence recognition, in particular to phoneme recognition in continuous speech. Because we are interested in sequence analysis, algorithms…
