Google Awards Grant to Rada Mihalcea

Rada Mihalcea In September 2005, Rada Mihalcea, CSE Assistant Professor, received $107,112 from Google Inc. in support of her research, "Finding Important Information in Unstructured Text: Algorithms for Keyphrase and Sentence Extraction." She plans to use the award to continue her research during the next two years.

"We want to develop ways to better access the information in books. This could take the form of back-of-the-book indices or succinct summaries," said Mihalcea in the UNT publication, InHouse. "We are hoping that this research will enable new ways of accessing the information that is stored in very large documents such as books. This won't replace book reading, but it will be a valuable interface that people can use to better determine if they are interested in a particular book."

For more information about this grant, read this UNT press release or this story in the North Texas Daily. For more details on the Rada Mihacea's research group, visit

The Computer Science and Engineering Department, in collaboration with the entire College of Engineering, participated in the 2005 Homecoming activities this year by hosting a tent in the Mean Green Village on Saturday, November 19. Each Department in the College provided poster displays and brochures and contributed to a continuously-running presentation highlighting some of the features and activities of each department, visible throughout the pavilion via several LCD displays.

In addition, CSE faculty and students provided the attention-getters for the pavilion by providing a Robot Race where visitors could bet on the winning robot for prizes. The robots and maze are part of the equipment used for the RoboCamp Summer Experience for young women sponsored by the department. Student-developed games from the LARC were also on display at two gaming centers where visitors could try out the games with assistance from CSE students. Additional monitors provided onlookers with a duplicate view as the players battled killer squirrels, invading aliens and samurai warriors.

During the event many of our faculty and students had a chance to visit with prospective students, alumni and retired faculty, and spread the word about UNT's newest college.

Saraju Mohanty Builds Research Group

Saraju Mohanty Saraju P. Mohanty, Ph.D., Assistant Professor, joined the CSE faculty in Fall 2004 when the department began its graduate program in Computer Engineering. Dr. Mohanty received his Ph.D. from the University of South Florida, Tampa in 2003 with a Master's from Indian Institute of Science, Banaglore, India. He is the author of 30 refereed ACM/IEEE transactions and ACM/IEEE conference papers.

During the last year, Dr. Mohanty has presented papers in three ACM/IEEE conferences. He presented "A Dual Dielectric Approach for Performance Aware Gate Tunneling Reduction in Combinational Circuits" at the 23rd IEEE International Conference of Computer Design (ICCD), San Jose, CA in October 2005. He presented "Analytical Modeling and Reduction of Direct Tunneling Current during Behavioral Synthesis of Nanometer CMOS Circuits" at the 14th ACM/IEEE International Workshop on Logic and Synthesis (IWLS) with partial travel support from ACM-SIGDA held in Lake Arrowhead, CA in June 2005. He presented "Reduction of Direct Tunneling Power Dissipation during Behavioral Synthesis of Nanometer CMOS Circuits", at the IEEE Computer Society Annual Symposium on VLSI (ISVLSI) held in Tampa, FL in May 2005.

Dr. Mohanty served as DAC/ISSCC student design contest judge for the 42nd design automation conference in 2005 and technical review committee member for Global Signal Processing Expo and Conference (GSPx), 2005.

Dr. Mohanty has established a very strong research group, which includes one Ph.D. and 6 M.S. Computer Science as well as Computer Engineering students. His research group pursues cutting edge research in several areas, such as CAD and Modeling for Nanoscale, VLSI Circuits, Synthesis and Optimization for Low Power, Power Aware System Design, and VLSI Architecture for Security and Copyright Protection. Further information about his research can be obtained at:

This semester Dr. Mohanty has been teaching CSCE 6651, Advanced VLSI Design. In Spring 2006, he will teach two courses, CSCE 4730, VLSI Design and CSCE 5730 Digital CMOS/VLSI Design. These two courses are the core for VLSI curriculum and provide strong foundations to computer engineering as well as electrical engineering students interested in VLSI.

Computer Security Program Expanding

Steve Tate Stephen R. Tate, Associate Professor, has been working to expand both research and educational opportunities in computer security. In working with Ph.D. student Vandana Gunupudi, Dr. Tate is preparing to release SAgent, a major security framework implementation for the JADE mobile agent platform. This software will be the first major easy-to-use implementation of cryptographic protections for general mobile code computation, and papers describing the system design and experimental results have been submitted for publication.

In addition to publications and presentations at recent conferences such as the International Conference on Information Security, and the Symposium on Information and Security, Dr. Tate has served on the program committee of many security conferences, including among others the International Workshop on Security in Networks and Distributed Systems, and the IASTED International Conference on Communication, Network and Information Security. Dr. Tate also is on the founding editorial board of a new journal, the Journal of Information Assurance and Security (JIAS).

Dr. Tate is launching a new research initiative in hardware-assisted security, looking into ways of increasing security and trust in distributed applications by making small changes in computer hardware. The first major step of this initiative is a Spring 2006 offering of CSCE 6933, an advanced topics course in hardware-assisted security. This course will be seminar-style, examining current research in this area, and students will be encouraged to "push the boundaries" with the goal of producing publishable research results.

On the educational side, Dr. Tate was involved in the first Texas Collegiate Cyber Defense Competition, coaching a team of 8 students (6 from CSE and 2 from the College of Business's Information Technology and Decision Sciences program) that participated in this contest in San Antonio in April. In this first-of-its-kind contest, student teams spent three days locking down and managing a small corporate-style network from attacks by a professional penetration testing team while still keeping the network functioning and available. Dr. Tate described the experience at the Colloquium for Information Systems Security Education in Atlanta, on a panel which was the highest evaluated panel discussion at the 4-day event. Dr. Tate is currently organizing a team for the next competition which will be held in March 2006.

UNT CSE Alumnus to Present Colloquium

David Rosenblum

Professor David S. Rosenblum will present "Content-Based Publish/Subscribe: Achievements and Challenges" at a CSE Colloquium on Friday, December 9, at 10:30 a.m. in NTRP B155. Professor Rosenblum received a B.S. summa cum laude in 1982 and M.S. in 1983 in Computer Sciences from North Texas State University (now UNT) and a Ph.D. from Stanford University. The following paragraph is an abstract of Professor Rosenblum's presentation.

For nearly a decade there has been a great deal of research on content-based publish/subscribe, in which a network of specialized routers is used to support publish/subscribe-style communication within distributed applications deployed over wide-area networks. This research has produced a number of novel router architectures, matching algorithms, routing protocols, implementation prototypes and other results that have been designed to achieve high throughput, scalability and expressive power in specific deployment scenarios. But the research has also revealed some difficult challenges stemming from the intrinsic content-based nature of the communication style, including challenges related to security, to mobility, and to the proper alignment of application characteristics with infrastructure characteristics. This talk will present an overview of this line of work, discussing the successes and limitations of past results as well as key problems that must be addressed in future work in order for content-based publish/subscribe to realize its true potential.

Currently, Professor Rosenblum is Professor of Software Systems in the Department of Computer Science at University College London and is Director of London Software Systems, a research institute established jointly by the Software Systems Engineering Group at UCL and the Distributed Software Engineering Group at Imperial College London. His research interests are in distributed event-based computing and software validation. He currently holds a Wolfson Research Merit Award from the Royal Society of the UK.

Before joining University College London, Professor Rosenblum was Chief Technology Officer at PreCache Inc., a startup company working in publish/subscribe technology. In 2002 he received the International Conference on Software Engineering's Most Influential Paper Award for his ICSE 1992 paper on assertion checking in C programs. He is an Associate Editor of the ACM Transactions on Software Engineering and Methodology and is currently the Chair of the ICSE Steering Committee. He is a Fellow of the IEEE (effective 2006), a Fellow of the IEE and a Chartered Fellow of the BCS.

CSE Department Seeks Assistance from Alumni

As our programs in Computer Science and Computer Engineering grow and change to meet the challenges of new technology and shifting demands from industry, our faculty and advisors seek your assistance in a number of critical areas of need.

1. Beginning in the Fall of 2006, the Computer Engineering students will begin taking the Senior Design course sequence for the first time. We would like to have industry-sponsored projects for them to tackle, as well as industry mentors and resources to interact with during the process.

2. Many of our students enjoy having the opportunity to perform independent research and development work through the Directed Studies course. These could also benefit from industry projects and sponsorship. These projects are usually on a smaller scale than those used in the Capstone Design courses. Typically a directed study is completed either by a single student or a small team of two to three students.

3. In order to attract quality graduates and undergraduates to our programs, sponsored scholarships and research fellowships are needed. Many companies have programs and funds to sponsor such efforts. Please check with your employer and encourage them to invest in the UNT Computer Science and Engineering program. Private donors are also welcomed and encouraged.

4. Our program can also benefit from donations-in-kind of equipment or funding to purchase equipment and set up student research and exploratory labs. Having equipment that provides exposure to a variety of platforms and tools enhances the skills set of our students and makes them more attractive to potential employers.

5. We are also looking for a sponsor to assist us in providing some small gift to our graduating students at both the undergraduate and graduate levels. Many departments provide some small memento that represents the university, the department and their major to each graduating student. Perhaps your company would be interested in sponsoring such a program.

If you or your employer are interested in any of these areas, please contact either our Department Chair, Dr Krishna Kavi, at or our undergraduate advisor, David Keathly, at

We want to hear from you! What have you been doing since graduating from UNT? Please send a few paragraphs and a picture to
