A critical step in automatic fingerprint matching is to automatically and reliably extract minutiae from the input fingerprint images. However, the performance of a minutiae extraction algorithm relies heavily on the quality of the input fingerprint images. In order to ensure that the performance of an automatic fingerprint identification/verification system will be robust with respect to the q...

The TCP-Friendly Rate Control (TFRC) is used as a streaming media transport protocol. Using the TCP congestion response function and current network conditions, TFRC adjusts its transmission rate to yield the maximum TCP-Friendly throughput when sharing capacity with TCP flows. Since TFRC was designed for wired networks, it does not achieve the maximum TCP-Friendly throughput in multihop ad hoc...

The challenge of designing an efficient Medium Access Control (MAC) protocol and analyzing it has been an important research topic for over 30 years. This thesis focuses on the performance analysis and enhancement of MAC protocols, particularly the random access protocols. Performance of the two widely known random access MAC protocols – the IEEE 802.3 MAC protocol that employs the Carrier Sens...

The invention of the Internet has ushered in advances in information era which has revolutionized the way we conduct business, advances our knowledge and promote life long learning. Each second a web server computer is bombarded with queries from numerous clients. It is then the web server system that responds to the queries by serving pages to the clients. Despite the popularity of the web ser...

Some examples are introduced to enhance exercise performance (from a single joint movement to runnlng and jumplng). There actually are numerous factors affecting exercise performance in but not limited to biomechanical, physiological, medical, and engineering aspects. In this session, I will focus on muscle mechanics that can be "manipulated" with some devices executable by a pracwioner or with...

II III Acknowledgements I would like to deliver my deepest appreciation to my instructors, Dr. Venkatesha Prasad Ranga Rao and Huaizhou Shi for their invaluable support, guidance and encouragement during the whole thesis project. I would like to express my gratitude to them for the time we spent together discussing the simulations and results. I am also very grateful to Dr.Cheng Guo for his gui...

InfiniBandTM Architecture (IBA) is envisioned to be the default communication fabric for future system area networks (SANs). However, the released IBA specification outlines only higher level functionalities, leaving it open for exploring various design alternatives. In this paper, we investigate four co-related techniques to provide high and predictable performance in IBA. These are: (i) using...

In order for systems in which tasks may fail to be faulttolerant, traditional methods deploy multiple servers as replicas to perform the same task. Further, in real time systems, computations have to meet strict time-constraints, a delayed output being unacceptable, even if correct. The effectiveness of sending task-replicas to multiple servers simultaneously, and using the results from whichev...
