This thesis considers systematic methodologies for nding optimized implementations for the fast Fourier transform FFT. By employing rewrite rules e.g., the Cooley-Tukey formula, we obtain a divide and conquer procedure decomposition that breaks down the initial transform into combinations of diierent smaller size sub-transforms, which are graphically(More)
providing the cardiac MRI data to test my algorithms. This project would not have been possible without help from Charnchai Pleumpitiwiriyawej whose work on Stochastic Active Contour Scheme formed the basis for this research. Special thanks are due to Hsun-Hsien Chang who helped me understand the principles of the level set method and gave me valuable tips(More)
The purpose of this article is to review the main neuroanatomic structures and the neurotransmission process involved at memory. Memory is dynamic based on the reunion of aspects of neuronal activation, in a process based on the individual experiences. It will be described the importance of limbic regions and their interaction during processing,(More)
Introduction In the last decades the internet has captured the attention of many users, not only for the services offered but also for the possibility to access a huge amount of information represented in different kind of formats like the on-line news. This huge amount of information is not easily interpreted, demanding tools and techniques which allow(More)
Acknowledgments I must admit that pursuing my graduate studies here at the University of Texas at Austin gave me a rare opportunity to be under the tutelage of talented professors. However, today I feel chiefly indebted to my advisor Dr. Allan MacDonald for the patience and sincerity he has shown me in regard to this dissertation. I would like to take this(More)
Child Mental Health Services have been dealing¸ over the last decades, with a growing number of children in need of evaluation and treatment. Recent studies estimate that 10 to 20% of children and adolescents met criteria for, at least, one psychiatric diagnosis, and that only one fifth gets appropriate treatment. Thus, in order to optimize service planning(More)
