In wireless communications, the broadcast nature can be explored to efficiently support multicast services while the difference in channel gains among the wireless links of users promotes multiuser diversity which can be used to improve multicast performance. This thesis proposes…

This thesis proposes a knowledge based expert system tool that can be used as an on- line controller for the charging/discharging of an energy storage system in a wind-diesel microgrid. The wind-diesel microgrid is modelled, and a typical energy storage…

Design is concerned with the question of how to construct an artifact or system to meet the desired specification and is normally categorized as either routine, non-routine or creative. Up until now, the study of knowledge-based design has concentrated on…

This thesis studies the dynamics of decision-making in a repeated auction game used as a basis for designing distributed resource management and task assignment mechanisms. We study the problem of coordinating a group of independent agents in a dynamic environment…

In the last few decades, the world of electric machine design, specifically induction machine design, has been reinvigorated by the introduction of power electronics. Where designers were once limited to a single alternating current waveform with constant voltage and frequency,…

Low-Density Parity-Check (LDPC) codes are one of the most powerful classes of error-control codes known to date. These codes have been considered for many recent digital communication applications. In this dissertation, we propose stochastic decoding of state-of-the-art LDPC codes and…

This thesis presents a theoretical and experimental study of the nonlinear behaviour of analog synthesizers' effects. The goal of this thesis is to evaluate and complete current research on nonlinear system modelling, both in and out of the field of…

In this thesis, we propose a new stochastic decoding algorithm for non-binary LDPC codes with d_v = 2, which is based on the concept of a mutliset, a generalization of the set that allows for multiple occurrences of the same…

Distributed estimation in a wireless sensor network has many advantages. It eliminates the need of the centralized knowledge of the measurement model parameters and does not have a single point of failure. Also, any sensor node can be queried to…

This thesis presents two methods to damp electromechanical oscillations in large power systems such as Trans-Canadian grid. A control method, used in conjunction with Wide Area Measurement System (WAMS), is proposed to damp very low frequency inter-area modes of very…
