Description: This article discusses dynamic intimate contact social networks and epidemic interventions. Abstract: Sexually transmitted diseases and infections are, by definition, transferred among intimate social settings. Although the circumstances under which these social settings are established and maintained may vary, the common prerequisite remains an intimate level of social atmosphere. For this reason, the development of sexually transmitted disease mathematical and computational models must utilize dynamic and evolving social network simulation. This paper presents DynSNIC (Dynamic Social Network of Intimate Contacts), a computational simulator created to embody the intimate dynamic and evolving social networks related to the transmission of sexually transmitted diseases and infections. DynSNIC's utilization by health professionals will facilitate evaluation of targeted intervention strategies and public health policies.

Description: This presentation discusses call arrival rate and mobility. The effect of call arrival rate on the capacity of a code-division multiple-access (CDMA) cellular network is evaluated. First the inter-cell and intra-cell interferences of every cell on every other cell are calculated for a given network topology. Then the capacity region for the number of simultaneous calls in every cell is defined for specified system parameters. This region is used to evaluate the new call blocking and handoff call blocking probabilities.

Description: This paper discusses efficient energy saving scheme for on-chip caches. Abstract: With the reduction in feature size the static power component, such as the leakage power, dominates the dynamic power consumption in the on-chip caches. It has been observed that all cache lines need not be kept alive at all times. Only a very few lines during a given window of time need to be actively powered from the footprint, i.e., they are accessed during that time. Earlier research has addressed the issue of how to determine the set of active lines and how long to keep them active (powered). Circuit techniques have also been developed to keep a cache line in low leakage state i.e., Drowsy State when the line is not being accessed or used. Such a cache is called drowsy cache. These circuit techniques try to achieve maximum reduction in the leakage power without losing the information content and with minimal performance penalty associated with power transitions. These techniques when used with optimal switching scheme, which decides when and what lines to drowse, results in maximum reduction in energy consumed. In this paper, the authors study the cache access pattern to evaluate them and arrive at an ...

Description: This presentation discusses the research of sensor synchronization, sensor grid routing, and voice over internet protocol (VoIP).

Description: This paper discusses enhancing the undergraduate research experience in a senior design context. Abstract: This paper presents an instructional framework developed by the authors that engages senior students in a 5-credit Research and Development course incorporating project development, implementation, entrepreneurship, innovation, creativity, teamwork, and communication. The paper discusses the development and accomplishments of the course over the past four years in the context of the Quality Enhancement Plan (QEP) - an initiative at the University of Houston intended to encourage the development and enhancement of undergraduate research skills. The philosophy behind the course is to provide training and real world, small-scale project experience through the completion of a full-project lifecycle from conceptualization to prototype. Brief discussion of those projects that resulted in provisional patents, refereed journal publications, and conference presentations will be given. Some of the features of the course, such as University and industry guest speaker series and final project evaluation by the department's Industrial Advisory Board, leading professionals, faculty, technical staff and peers will be examined. The paper concludes by outlining a set of short term and long term goals for the future direction of the course.
