Greetings from the CSE Chairman

Chairman Krisha Kavi

Dear CSE Alumni and Friends,

I am pleased to share with you that our B.S. in Computer Engineering has been accredited through 2014. It is very rare that a new program receives full accreditation. We should be proud of this achievement. You can read about this and other department news below. Robocamp was a big success this year and plans are being made for next summer. Congratulations to Robert Akl, Ram Dantu, and Rada Mihalcea: all received tenure and were promoted to Associate Professor for this academic year.

Our Department of Computer Science and Engineering is growing. While our enrollment is holding steady with about 632 undergraduates and 167 graduate students, our new B.A. in Information Technology program has added over 30 new students to our department. This program was initiated by our CSE Advisory Board and developed by our faculty over the past two years so we are excited to welcome these new students to our CSE family.

Alumni support is important to the future of our department. In this newsletter below, we invite you to help us build a strong network of alumni. We are thinking about hosting a retreat so you can network with other alumni and offer us feedback on our programs. I hope you will want to participate. We invite you to come back to CSE at UNT.

B.S. in Computer Engineering Receives Full Accreditation

ABET

ABET (Accreditation Board for Engineering and Technology) has notified us that our B.S. in Computer Engineering program has received accreditation through 2014 and that we will be evaluated again in 2013 to extend the accreditation. It is very rare that a new program that started in 2003 and graduated its first class in 2007 receives full NGR. Next General Review means that there were no deficiencies or weaknesses in our B.S. in Computer Engineering program.

In 2007, ABET reviewed our Self-Study. Last Fall, ABET visitors came to our CSE department to review our program, including all course materials for undergraduate classes. They also met with faculty, alumni, and students about the new program. Thanks to everyone who participated in these discussions. At the end of their time here, the visitors found no deficiencies or weaknesses. They had only three minor concerns for the program that have already been addressed. During the summer, ABET approved the visitors' recommendations that our program receive full NGR.

Now the CSE Department must prepare for our accreditation review for the B.S. in Computer Science. Faculty will be collecting materials from classes this year. A Self-Study for Computer Science will be written in Spring 2008. Dr. Robert Akl is the new Chair of the Undergraduate Studies Committee and he will be leading this effort for reaccreditation of our B.S. in Computer Science program.

Robocamp Logo

The CSE Robocamp program, administrated by Dr. Robert Akl and David Keathly, has received a second $30,000 grant from the Motorola Foundation. This grant, coupled with the second year funding from the Texas Workforce Commission Youth in Technology grant awarded in 2007, has assured that a full complement of camps in Denton, Dallas and surrounding communities will be held in the Summer of 2009.

In the Summer of 2008, a record number of camps were held, including ten youth camps and two adult camps for counselors and teachers. 2008 also marked the first year that camps were held for young men as well as young women. Robocamp has served over 400 young people since the program began in 2005.

The programs in the summer of 2009 will complete the fifth consecutive year for the program. Recent surveys of students who attended Robocamp and have subsequently graduated high school have shown a high percentage attending college in Science or Engineering disciplines, at least partly influenced by their camp experience. A detailed report will be released during the Fall 2008 semester.

The VLSI Design and CAD Laboratory (VDCL, http://vdcl.cse.unt.edu) has reported that Dr. Saraju P. Mohanty was elevated to senior member of IEEE in May 2008. Senior member status is awarded to members who have at least 10 years of contributions to the profession. Only 8.1% of approximately 376,000 IEEE members have received this status.

Dr. Saraju Mohanty has published a book, Low-Power High-Level Synthesis for Nanoscale CMOS Circuits, along with co-authors Nagarajan Ranganathan, Elias Kougianos, and Priyadarshan Patra. This book addresses the need for analysis, characterization, estimation, and optimization of the various forms of power dissipation in the presence of process variations of nano-CMOS technologies. The authors show very large-scale integration (VLSI) researchers and engineers how to minimize the different types of power consumption of digital circuits.

The material deals primarily with high-level (architectural or behavioral) energy dissipation because the behavioral level is not as highly abstracted as the system level nor is it as complex as the gate/transistor level. At the behavioral level there is a balanced degree of freedom to explore power reduction mechanisms, the power reduction opportunities are greater, and it can cost- effectively help in investigating lower power design alternatives prior to actual circuit layout or silicon implementation.

The book is a self-contained low-power, high-level synthesis text for Nanoscale VLSI design engineers and researchers. Each chapter has simple relevant examples for a better grasp of the principles presented. Several algorithms are given to provide a better understanding of the underlying concepts.

The initial chapters deal with the basics of high-level synthesis, power dissipation mechanisms, and power estimation. In subsequent parts of the text, a detailed discussion of methodologies for the reduction of different types of power is presented including:

  • Power Reduction Fundamentals
  • Energy or Average Power Reduction
  • Peak Power Reduction
  • Transient Power Reduction
  • Leakage Power Reduction

Low-Power High-Level Synthesis for Nanoscale CMOS Circuits provides a valuable resource for the design of low-power CMOS circuits. It was written for Nanoscale VLSI design engineers and researchers; for students from senior undergraduate onwards in Computer Engineering, Electrical Engineering, and Computer Science interested in low-power VLSI.

Finally, we welcome a team of four researchers, Shu-Song Chen, Li-Te Lee, Yu-Ting Pai, and Jih-Chieh Hsu, who are here at UNT visiting VDCL. They are with the research group of Professor Shanq-Jang Ruan from National Taiwan University of Science and Technology. They have been funded by their university for up to a year to conduct research at VDCL in the areas of low-power digital design and digital watermarking.

News for Alumni

Calling All Alumni

We want your help!

The CSE department at UNT would like your thoughts and suggestions about how we can build a strong network of alumni. The department of CS (and now CSE) existed for more than 30 years with a large number of graduates. We would really like you to actively participate in the departmental activities and take an active role in shaping its future. We are thinking about a short retreat to create a networking among alumni and seeking feedback from you. One option would be start the event on a Friday afternoon and wrap up by Saturday evening, but you are welcome to suggest other options.

We will set aside time for you to network with other graduates. We will have brainstorming sessions on what is important to you. We will have several small groups working on different issues that will have an impact on the department's future. We want to hear if you would be interested in participating in such an activity, and if you would be willing to help us with the event. Please let us know by emailing your thoughts to Genene Murphy (genene@unt.edu).


Retired Faculty Member Visits CSE Department

Denis Conrady visit to Discovery Park
Don Retzlaff, Denis Conrady, Robert Brazile, Kathleen Swigger, and Tom Irby

Dr. Denis Conrady was one of the first faculty members in the Computer Science Department. He joined the faculty in 1974. He retired in 1998 and he and his wife Catherine moved to Terre Haute, Indiana. The department's printed Alumni Newsletter included an article about Denis in Spring 2006.

During this past summer, Denis visited the department for the first time since the department moved to Discovery Park. After having lunch with fellow retired faculty member Tom Irby, Tom's wife Jackie, and current faculty member Don Retzlaff and his wife Elisa, they visited the department and Discovery Park. Don and Tom showed Denis around the facility, including several of the department's labs and classrooms. He was also able to visit with several of the faculty.

He was quite taken with the complex, remarking that it seemed like there was more room in one office that we used to have in the entire department. Although he enjoyed the visit, no one could convince him to come out of retirement. You can see more pictures of Dr. Conrady's visit in the website media gallery here.


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.


DC BEST 2008 Invites Alumni Support

Texas Best

DC BEST (Denton County Boosting Engineering, Science, and Technology) is a non-profit organization and a hub of BEST Robotics providing middle and high school students a learning opportunity that is fun, while growing in the knowledge of engineering, science, technology, and team building.

DC BEST will hold its local competition in October 2008. Then for the first time, the UNT College of Engineering will host the state competition known as Texas BEST on November 14 and 15, 2008. More about this state tournament can be found in this UNT press release.

High school teachers and instructors from the UNT College of Engineering volunteer their time to make this important competition possible. DC BEST relies on industry support to make the event possible and free to the local schools. This recent article in the Denton Record-Chronicle describes this importance of this competition.

CSE alumni can help in two ways. The first way is for you or your company to donate money to this worthy cause. This event is not possible without support from alumni and industry. Checks can be made payable to DC BEST and mailed to DC BEST, c/o Leticia Anaya, University of North Texas, 3940 N. Elm  F115M, Denton, TX 76207.

The second way you can help is to volunteer your time. Volunteers serve as judges, referees, and provide overall support to make this event possible. The Kickoff was held here at Discovery Park on Saturday, September 13. At the Kickoff, the rules of the game were explained, the gamefield was demonstrated, and the robotic supplies were given to the schools.

The second event of the competition is Mall Day, which is Saturday, October 18, from 8 a.m. to 5 p.m., at the Golden Triangle Mall in Denton. The teams test their homemade robot on the actual game field. This trial allows the teams to debug or correct problems before the actual Game Day.

The final event of the local competition is Game Day, which is Saturday, October 25, at the UNT Coliseum. The teams gather for a robotics tournament that continues until a champion is declared through a process of point elimination.

If you would like to volunteer to help with DC BEST or Texas BEST, please contact Mr. Bill Stamm, DC BEST Director at w.stamm@verizon.net or Ms. Leticia Anaya, Assistant DC BEST Director at Lanaya@unt.edu.

We want to hear from you! What have you been doing since graduating from UNT?
