September 2007   CSE News Alumni News Student News College of Engineering News UNT News Greetings from the CSE Chairman Dear CSE Alumni and Friends, 2007 has been a productive year so far for our Department of Computer Science and Engineering. Our enrollment is holding steady with about 600 undergraduate students and 171 graduate students. Our research funding has increased this year. From January to August 2007, we have been awarded over $1.7 million. You can read about several of our new research grants below. To compare how our department has done over the last few years, click HERE for a detailed report. Our CSE department is changing and improving. Over the summer, the Texas Higher Education Coordinating Board approved a plan that will change our B.A. in Computer Science to a B.A. in Information Technology beginning in Fall 2008. This new program is the only one in the state of Texas with an undergraduate degree in IT and I believe it will be very attractive to prospective students and help our department grow even more. Alumni support is important to the future of our department. The ABET Computer Engineering accreditation team will be here October 21-23. If you are available to meet with the visiting team, send me an email. ABET teams really want to find out how our graduates feel about their education. So if you have the time, we really would like you to meet with the visiting team. Your participation could help our CSE department to achieve accreditation in our Computer Engineering program. Thanks for your support of CSE and UNT. Krishna M. Kavi Chairman

Department of Computer Science and Engineering News NSF Awards Grant to Dr. Kathleen Swigger The National Science Foundation has awarded $499,252 to Dr. Kathleen Swigger to study the performance of student work teams in four countries as the teams write software. The project will create curriculum materials to teach students the best ways to work more effectively in global software teams. The students working on this project will be from UNT, Panama, Great Britain, and Turkey. Dr. Swigger said, "Outsourcing is not going to go away. There is a growing need to ensure that computer science students are taught the necessary skills to deal with this new type of programming. Students need to know how to use technology to work in culturally mixed and geographically distributed work teams, because distributed software development is becoming the norm." Dr. Swigger says her research will have implications for geographically distributed collaborative learning teams in general, and furthers UNT's reputation as a student-centered, public research university. She adds the project has drawn interest from several major DFW employers. "Travelocity, Boeing, and Lockheed Martin do similar projects at their companies, and they are acting as advisors on the project." Dr. Saraju P. Mohanty Receives NSF Research Grant Dr. Saraju P. Mohanty received a NSF research-grant to support his research in nanoscale CMOS modeling and estimation. The project titled "A Comprehensive Methodology for Early Power-Performance Estimation of Nano-CMOS Digital Systems" will span over three years, 2007-2010. The primary goal of this project is to facilitate the estimation of power and performance of digital systems described in MATLAB/Simulink when constructed using nano- CMOS technology. The research will result in the development of new building blocks, collectively grouped as a new MATLAB toolbox, called Power Box. Power Box will be fully parameterized for power and performance to facilitate fast modeling and estimation of systems. The proposed research involves the design and development of theory, algorithms, implementations, and experiments, with sufficient scope for education and training of undergraduate and graduate students in VLSI design and system modeling. This project can effectively serve the large, complex, digital system design and simulation community of researchers, in both academia and industry to boost further research and to reduce design cycle time. Dr. Buckles and Dr. Yuan Collaborate on Grants Photo by Andrew McLemore Dr. Bill Buckles and Dr. Xiaohui Yuan were awarded a National Science Foundation grant of $75,000 for a project that will map the effects of flood damage. Their project, "A New Tool for Economic and Environmental Planning: Expanding the Boundaries of LiDAR," will use LiDAR, or "light detection and ranging," to create a 3D image of varying terrain to predict the path of floodwater during hurricanes and other floods. In addition, Dr. Buckles and Dr. Yuan were awarded a supplemental grant for a collaborative project with researchers at the Hefei University of Technology of China. This project is sponsored by both the NSF and the National Nature Science Foundation of China (NSFC). They were awarded $49,800 by the NSF and the Chinese partner was awarded ¥50,000 by the NSFC. This supplemental project will focus on extending their results to the visualization of the city model and the simulation of disaster scenarios, such as flooding. During this project, Dr. Buckles and Dr. Yuan expect a visit from their Chinese partner in the middle stage of their research. During the later stage of the project, Dr. Buckles and Dr. Yuan plan to visit their partners in China for discussion and result integration. Dr. Huang's Joint Project is Funded by NSF The National Science Foundation has issued a $250,000 award to the proposal by Dr. Yan Huang (PI, Computer Science), Dr. Miguel Acevedo (Geography/BEE), Dr. Xinrong Li and Dr. Shengli Fu (Electrical Engineering), and Dr. Ruthanne Thompson (Biology). This three-year project will develop a publicly available environmental monitoring computing research testbed that incorporates an open sensor network system and tools with intertwined wired and wireless sensors. The immediate research and education projects enabled include energy efficient map interpolation, robust localization models, code designs for cooperative communication in wireless sensor networks, simulation models for near real time environmental monitoring and modeling, and modeling for K-12 teachers/students. The project team also includes researchers and personnel from Biology (Dr. Tom Waller), Computing Support and Service, the City of Denton, Texas, the National Park Service, and the National Weather Service of Texas. Software Development Partnership Expands with NSF Grant The National Science Foundation has awarded a $10,000 planning grant to allow UNT to expand its current partnership in a Net Centric Software Consortium. Dr. Krishna Kavi is the Principal Investigator and the initial director of the Net Centric software consortium that was established with the four major universities in the Dallas-Fort Worth area. The current partners are the University of Texas at Dallas, the University of Texas at Arlington, and Southern Methodist University. UTD and SMU also received $10,000 from NSF to collaborate with UNT as well as Arizona State University, University of California at Irvine, and Southern Illinois University to form an Industry/University Collaborative Research Center (I/UCRC). Each university partner has one year to recruit at least five industrial members, paying annual membership dues, before the I/UCRC can be established. The universities in the Dallas-Fort Worth area will concentrate on developing high-quality software for new generation applications that involve systems on a network (Net Centric systems). The US Department of Defense has expressed strong interest in the research. Dr. Kavi says, "We are inviting about 200 companies here in the Dallas-Fort Worth area to join the consortium. In February 2008, a meeting will be held to explain the I/UCRC concept, benefits for industry and how they can join the center. In short, by joining the consortium, industry will have royalty-free access to the research we are conducting in the center." Dr. Kavi predicts the consortium will be known as a leading research alliance in the United States, conducting significant research projects for the federal government and industrial customers and attracting the best research faculty and students from all over the world. The consortium will also help in creating a trained workforce to meet the needs of US industries.

He currently works in the RyderOnline development team where he is responsible for maintaining and supporting several J2EE applications. Apart from learning new technologies and gadgets, Saqib loves to travel and meet new people. On weekends, he enjoys hanging out with old friends and he also likes to bowl and golf. We want to hear from you! What have you been doing since graduating from UNT? Please send a few paragraphs and a picture to AlumniFocus@cse.unt.edu. How Alumni Can Help Student Organizations The Fall semester once again brings the opportunity for students to become involved in a variety of professional societies, special interest groups and honor societies. These organizations can benefit them in many ways, as our alumni are aware. But how can you assist our student organizations to contribute effectively at UNT? Here are a few suggestions: Volunteer as a guest speaker or recommend someone at your company or in your "network" that would be interesting and educational Help organize a field trip to your company for something interesting Volunteer as a mentor to work with a small group of students to develop their leadership skills and invite them to the DFW area section meetings of the various societies if you are a member Donate funds or materials to help the organizations provide programming and host special events, or sponsor a scholarship to subsidize the membership fees for students. Encourage your company to sponsor an event or other funding for these organizations in exchange for advertising and opportunities to recruit potential employees Sponsor a student to attend one of the Student Leadership conferences or a technical conference sponsored by a society Be a part of our National Engineers Week activities Visit a student group meeting once a year so the students will begin to understand their importance and potential impact on their immediate and long term career success Soon we will also have a number of honor societies, including Tau Beta Pi, Eta Kappa Nu, and Upsilon Pi Epsilon. These groups also need help from our alumni in a fashion similar to those listed above. Also if you are an honor society member, you can assist with induction ceremonies and other events. Please consider helping us create an active, supportive and vibrant collection of student professional and honor organizations. Contact David Keathly for more information on these organizations at dkeathly@cse.unt.edu.

UNT Team Takes on the Zodiac Killer Professor Ryan Garlick's Symbolic Processing class in the Department of Computer Science and Engineering is attempting to decode the unsolved 340-character cipher sent by the infamous Zodiac killer to the San Francisco Chronicle on November 8, 1969. The David Fincher movie Zodiac has stirred new interest in the case, and the students hope to use modern techniques on this nearly 40 year old mystery. The bay area serial killer sent an earlier message to newspapers that was successfully decoded, but this text of this message has never been revealed. Even using heuristic methods, the amount of processing required is enormous. Students are hoping to develop methods to reduce the number of keys that must be evaluated. More information will be forthcoming, along with a link to use your computer to help in the deciphering process. If you have access to processing resources that can assist with the project, please contact Ryan Garlick at garlick@unt.edu.
