Greetings from the CSE Chairman

Dear Alumni and Friends,

Our first alumni email newsletter was such a success that we decided to send you a second edition. We heard from many alumni, including those featured in this edition. Several alumni and friends showed their support by sending donations to the department. I hope you will continue to stay in touch with us and find ways that you can contribute to our program here at UNT.

Thanks to those of you who registered in our Alumni Database. If you haven't registered yet, please go to our Alumni Database. With this information, we can continue to send you future editions of this newsletter, as well as our mailed Alumni Newsletter. To update information you have previously entered on our website, visit Alumni Update.

We do not have email addresses for all of our graduates, but we are actively searching for them. Until we have them all, I ask your help by forwarding this email newsletter to other UNT Computer Science Alumni. I hope they will respond by registering their updated information so that they can be added to our list.

We encourage all of you to show your support and keep in touch with us by telling us what you are doing, how your education at UNT aided you in your work, and how you would like to see our program change. We also encourage you to share news of our department with prospective students. Recruiting new students is an important way of contributing to our program.

Thank you for being an active supporter and a friend of CSE and UNT.

Bachelor of Science Degree in Computer Science Accredited for 18th Year

The Computing Accreditation Commission (CAC) of the Accreditation Board for Engineering and Technology (ABET) granted accreditation to the University of North Texas Bachelor of Science degree in Computer Science for the 18th consecutive year. The designation recognizes the high quality of the department's programs, faculty, Dr. Thomas Irby and curriculum.

Dr. Thomas Irby, as Chairman of the Undergraduate Committee, was the Coordinator for the ABET accreditation. Dr. Irby said, "The continued accreditation of the B.S. in Computer Science degree is important because it provides an independent assessment of the quality of the program. The amount of work required to prepare the accreditation documents and materials is substantial. The process gives us the opportunity to evaluate what we are doing and to make sure that our programs continue to be up to date and relevant in today's world."

Dr. Sweany Researches Compiler Optimization

Dr. Phil Sweany Dr. Philip Sweany's research focus has been compiler optimization for architectures with instruction-level parallelism (ILP), such as Texas Instruments' C6000 series of DSP processors.

Cell phones are everywhere. And the features available in cell phones increase with each new generation of phones. But what forms the "guts" of a cell phone? A Digital Signal Processing (DSP) chip. DSP chips need to be powerful so that the phone works and has as many features as possible. At the same time, DSP chips need to limit the amount of power they consume. You don't want to have to re-charge your battery after 5 minutes of phone use. Many people realize that producing high-performance, low-power, low-cost DSP chips is necessary for cell phone applications. What many people don't realize is that how we translate software written in "people-friendly" languages into "computer-friendly" language is a very important factor in cell phone performance. Programs that do such translation are called compilers.

Within the field of ILP compilers, Sweany has worked mostly in register assignment and instruction scheduling, defining ways to improve global scheduling, software pipelining, and partitioning of computation among ILP clusters. He and co-workers have built the Rocket C compiler which is retargetable to a wide range of ILP architectures. For more information about Dr. Sweany and his research, visit his website at

New Laboratory Established by Dr. Mohanty

Saraju P. Mohanty The VLSI design and CAD Laboratory was established at the Computer Science and Engineering Department (F231) in Fall 2004. The laboratory homepage is located at The research focuses on preparing the next generation EDA tool to produce nanometer VLSI circuits considering physical phenomena, such as cross-talk, power supply noise, and interconnect delays, while reducing both static and dynamic power. We are looking for both masters and Ph.D. students to carry out such research. Students with strong electrical or computer engineering backgrounds and programming experience are preferred. For more information about this new laboratory, contact Dr. Saraju Mojanty at

Ian Parberry and Timothy Roden's Paper Presented in Liverpool

Faculty members Ian Parberry (right) and Timothy Roden had a paper presented at the Second Annual International Workshop in Computer Game Design and Technology. The November conference was hosted by John Moores University in Liverpool, England. The paper, entitled "Portholes and Planes: Faster Dynamic Evaluation of Potentially Visible Sets," describes a new algorithm for computing visibility in indoor 3D environments.

"Computing visibility is vital for real-time 3D graphics applications such as games," said Roden. "Without it, it would be impossible to render complex indoor scenes at interactive frame rates. We can also use visibility data for other tasks. For example, we might use a potentially visible set to compute the actions of AI-controlled agents moving through a 3D environment. This research is aimed at creating a faster algorithm that can be used in non-rendering tasks where a PVS is needed."

Roden is a Lecturer and Ph.D. student in Computer Science at UNT. Roden's advisor and co-author of the paper is Professor Ian Parberry. Roden and Parberry are excited about the prospects for the future of entertainment computing research. The Liverpool paper represents the fourth paper the pair have had accepted this year related to entertainment computing. The paper is available for download at

Students Learn C++ with Connect Four

Students in Professor Ryan Garlick's CSCI 1120 class are putting their C++ skills to use in a Connect Four Tournament. Given a game board object and assigned a color, each student creates a program to return the column in which to drop their token.

Students' programs are then paired against one another in a single elimination tournament in which the first to get four tokens in a row wins. A time limit of 10 seconds per move is enforced to ensure the use of heuristics rather than an exhaustive search of all board possibilities. The project is designed to teach object oriented programming and encourage exploration of algorithms outside the scope of the class.

The finalists employed sophisticated methods of evaluating potential moves, recursively scoring potential boards several moves ahead. Tournament winner John Rizzo's program was wrapped in an interactive graphical application and used as the opponent at recruiting event kiosks.
