Cell Placement in a CDMA Network
Date: September 1999
Creator: Akl, Robert G.; Hegde, Manju V.; Naraghi-Pour, Mort & Min, Paul S.
Description: This presentation discusses research on cell placement in a CDMA network. In order to enable iterative cell placement the authors use a computationally efficient iterative process to calculate the inter-cell and intra-cell interferences as a function of pilot-signal power and base station location.

CCAP: A Strategic Tool for Managing Capacity of CDMA Networks
Date: 1998
Creator: Akl, Robert G.
Description: This presentation discusses CCAP, a strategic tool for managing capacity of CDMA networks. CCAP is a graphical interactive tool for CDMA that calculates the coverage area, call capacity of a CDMA network, and subscriber network performance to optimize capacity.

Call Admission Control Scheme for Arbitrary Traffic Distribution in CDMA Cellular Systems
Date: September 2000
Creator: Akl, Robert G.; Hegde, Manju V.; Naraghi-Pour, Mort & Min, Paul S.
Description: This presentation discusses call admission control (CAC). The authors define a set of feasible call configurations that results in a CAC algorithm that captures the effect of having an arbitrary traffic distribution and whose complexity scales linearly with the number of cells.

WARM SRAM: A Novel Scheme to Reduce Static Leakage Energy in SRAM Arrays
Date: February 2004
Creator: Gomathisankaran, Mahadevan & Tyagi, Akhilesh
Description: This presentation accompanies a paper discussing research on a novel scheme to reduce static leakage energy in SRAM arrays. The increasing sub-threshold leakage current levels with newer technology nodes have been identified by ITRS (2001) as one of the major fundamental problems faced by the semiconductor industry. Concurrently, the expected performance improvement and functionality integration expectations drive the continued reduction in feature size. This results in ever-increasing power per unit area and the accompanying problem of heat removal and cooling as stated in J.M.C. Stork (1995). Portable battery-powered applications, fuelled by pervasive and embedded computing, have seen tremendous growth and have reached a point where battery energy and power density can't be increased further according to T. Bell (1991). This raises the computational throughput per watt target for the future technology nodes. SRAM arrays which are used widely as a system component, such as caches and register files, in both high-performance and portable systems, are getting to be dominant power consumers because of their large capacity and area. Hence any reduction in cache energy can result in considerable overall power reduction. The authors propose a novel circuit technique using depletion mode devices, to reduce the static energy of SRAM array ...

Retention and Recruitment of Women in Computer Engineering
Date: July 2006
Creator: Akl, Robert G. & Garlick, Ryan
Description: This presentation discusses strategies and goals for recruiting more women to Computer Science and Engineering degree (CSE) programs at the University of North Texas (UNT). It also describes a series of activities aimed at improving retention rates of women students already in our programs. Such recruitment and retention of women is critical to the country's efforts to increase the number of engineering professionals, and is a priority for the CSE Department at UNT.
