We present our design exploration of reconfigurable Threshold Logic Gates (TLG) implemented using silver–chalcogenide memristive devices combined with CMOS circuits. Results from simulations and physical circuits are shown. A variety of linearly separable logic functions including AND, OR, NAND, NOR have been realized in discrete hardware using a(More)
This paper studies a class of enhanced diffusion processes in which random walkers perform Levy flights which are frequently observed in statistical physics and biology. Levy flights are shown to have several attributes suitable for the global optimization problem, and those four algorithms are developed based on such properties. We compare new algorithms(More)
This paper examines the major barriers to the deployment of geothermal, small hydro and advanced coal power generation technologies in Vietnam. It ranks their severity by applying the analytical hierarchy process to data from a survey of 37 domestic experts and stakeholders. Key barriers to a wider penetration of small hydro generation technologies are(More)
The electrical and computer engineering department strives to provide high quality degree programs that emphasize fundamental principles, respond to the changing demands and opportunities of technology, challenge the exceptional abilities of Rice students, and prepare these students for roles of leadership in their chosen careers. In support of this goal,(More)

They found that the student passed the final oral examination. Dedicated to my parents and Owen. iv ACKNOWLEDGMENTS I would like to thank Dr. Barney Smith who(More)
The Fukui Declaration from the Ninth Asia Pacific Economic Cooperation (APEC) Energy Ministers Meeting (EMM-9), June 2010, states that " smart grid technologies, including advanced battery technologies for highly-efficient and cost-effective energy storage, can help to integrate intermittent renewable power sources and building control systems that let(More)
The following individuals read and discussed the thesis submitted by student Subramaniam Venkatraman, and they evaluated his presentation and response to questions during the final oral examination. They found that the student passed the final oral examination. ACKNOWLEDGMENTS I would like to thank Dr. Barney Smith who encouraged me all along and kept me(More)
Acknowledgements I thank my supervisor, Karen Smith, for her excellent guidance during the years of my doctoral studies. Without her support, expertise and, most importantly, encouragement this dissertation would not exist the way it does now. Also, I thank Matthew Emerton for some helpful conversations and for entrusting me with early manuscripts of [EK99,(More)
