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…

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…

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…

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…

Translating documents into multiple languages represents an extremely large expensefor businesses, governments, and international agencies. In Canada, for example, it isa requirement that all ocial documents exist in both ocial languages, French andEnglish. This has produced a large translation industry…

Wireless and Internet video applications are hampered by bit errors and packet errors, respectively. In addition, packet losses in best effort Internet applications limit video communication applications. Because video compression uses temporal prediction, compressed video is especially susceptible to the…
