This shared interest is due to the facts that an arbitrary quantum logic gate may be expressed, up to arbitrary accuracy, via a circuit consisting entirely of variations of the quantum multiplexer, and that certain one player games, the history dependent Parrondo games, can be quantized as games via a particular variation of the quantum multiplexer. However, to date all such quantizations have lacked a certain fundamental game theoretic property. The main result in this dissertation is the development of quantizations of history dependent quantum Parrondo games that satisfy this fundamental game theoretic property. Our approach also yields fresh insight as to what should be considered as the proper quantum analogue of a classical Markov process and gives the first game theoretic measures of multiplexer behavior.

This is the first event in a biennial conference series and it follows the very successful 2001 Richard Tapia Symposium celebrating diversity in computing. The conference honors the many contributions of Richard Tapia, a leader in the field of computational mathematics as well as a strong and outspoken advocate for diversity.This year's theme of "Building Diverse Leadership in Computing" highlights the leadership that Richard Tapia has not only exhibited throughout his career, but also the role that he has played in developing that leadership in so many others. The overall program reflects this theme in its selection of keynote and plenary speakers, who are all recognized leaders in their respective fields. In addition, the technical program co-chairs, Monica Martinez-Canales and Pamela Williams have developed a strong program consisting of co...

We assume that the resulting permutation degree, n, can be 10,000,000 and larger. The key idea is to build the new permutation representation using the conjugation action on a conjugacy class of subgroups of prime order. A unique signature for each group element corresponding to the conjugacy class is used in order to avoid matrix multiplication. The requirement of at least n matrix multiplications would otherwise have made the computation hopelessly impractical. Additional software optimizations are described, which reduce the CPU time by at least an additional factor of 10. Further, a special data structure is designed that serves both as a search tree and as a hash array, while requiring space of only 1.6n log 2 n bits. The technique has been implemented and tested on the sporadic simple group Ly, discovered by Lyons [9], in both a sequential (SPARCserve...

The results from this program were used to update reference files and make changes to CALCOS, the COS data processing software. Improvements to the standard data products are discussed. For the FUV channel, we have begun development of a flat-field correction. As an intermediate step, grid wire shadows are now ignored when combining FP-POS exposures. Pulse-height filtering has been activated to reduce background features. For the NUV channel, vignetting corrections are incorporated in the flat field file. For both channels, improvements have been made in the wavelength scales, flux calibration, and data quality flagging. Additional data are included in the FITS products to allow users to perform customized processing.
