A novel genetic algorithm (GA) for the design of a canonical signed powerof-two (SPT) coefficient lattice structure quadrature mirror filter bank is presented in this paper. Genetic operations may render the SPT representation of a value noncanonical. In this paper, a new encoding scheme is introduced to encode the SPT values. In this new scheme, the canonical property of the SPT values is preserved under genetic operations. Additionally, two new features that drastically improve the performance of our GA are introduced. (1) An additional level of natural selection is introduced to simulate the effect of natural selection when sperm cells compete to fertilize an ovule; this dramatically improves the offspring survival rate. A conventional GA is analogous to intracytoplasmic sperm injection and has an extremely low offspring survival rate, resulting in very slow convergence.(2) The probability of mutation for each codon of a chromosome is weighted by the reciprocal of its effect. Because of these new features, the performance of our new GA outperforms conventional GAs.

First and foremost, I would like to thank my supervisor, Professor Fred Nitzsche for his academic guidance and financial support throughout the entire research period. For many aspects, he contributed to my wonderful experience as being an international student in Canada. I greatly appreciate Professor Spyridon Voutsinas and Dr. Vasilis Riziots at the National Technical University of Athens for the time that they give me to develop the aeroelastic code. I am grateful to Michael Rose, German Aerospace Center (DLR) for his interest in my research and collaboration on the development of the discrete-time periodic Riccati solver. I would like to acknowledge the financial support given by the Ontario Center of Excellence during my four-month visit to
