Greetings from the CSE Chairman

Dear CSE Alumni and Friends,

With the beginning of 2007, I want to share some enrollment data with you about our CSE department. Our undergraduate enrollment for women in Computer Engineering has doubled from 8% in Fall 2005 to 16% in Fall 2006. Our minority enrollment has been steady at approximately 33%. In Computer Science, our undergraduate minority enrollment has increased slightly from 31% to 33% and our female enrollment has also increased from 10% to 12%. On the graduate side, our female population in Computer Science has grown from 19% in Fall 2005 to 26% in Fall 2006. The number of graduate women in Computer Engineering has held steady at just above 40%. We are making progress in attracting qualified women and minority students to our CSE program.

Many exciting things have happened since the Fall 2006 semester ended. I am pleased to announce that UNT has signed a Memorandum of Understanding with three other area universities to form a Net-Centric Software Engineering Consortium. During the semester break, I traveled to Taiwan and made contacts for future student exchanges. Dr. Oh received news of a NSF grant for his research. Our department will host the 3rd Southwest Regional Collegiate Cyber Defense Competition in March 2007. Dr. Steve Tate was instrumental in bringing this competition to UNT for the first time at Research Park. You can read more details about these happenings and other news below.

The UNT College of Engineering is planning several activities for National Engineers Week, February 19-23, 2007. You are invited to attend our annual College of Engineering luncheon at Research Park on Wednesday, February 21, from 11-1 p.m. Following the luncheon, we are hosting a Graduate Studies Open House from 1-2 p.m. on the same day. If you are thinking about attending graduate school, I invite you to this event to get more information about our graduate program. Other activities have been planned and you can read more information below. I hope you will participate in these events during National Engineers Week.

UNT Signs Agreement to Form Net-Centric Software Engineering Consortium

Dr. Krishna Kavi has announced that the University of North Texas has signed a Memorandum of Understanding with three other area universities to form a Net-Centric Software Engineering Consortium. The other universities are the University of Texas at Arlington, the University of Texas at Dallas, and Southern Methodist University.

Research in new software engineering methodologies is needed. Net-centric operation is an emerging paradigm and family of tactics, techniques, procedures, and capabilities that use a networked environment to meet new and evolving challenges through information integration and adaptive solutions. Net-centric computing focuses on the network as a way of integrating diverse resources and services. Its primary goal is to support dynamic creation of solutions to unanticipated threats and malfunctions. Applications of net-centric systems range from emergency response systems to defense systems, medical and healthcare systems, transportation systems, and other mission- and safety-critical systems.

Now that the four universities have signed this agreement, the group is working to develop industry membership agreements. They plan to submit a proposal to the National Science Foundation's CISE (Computer and Information Science and Engineering) Computer Research Infrastructure program. They also plan to develop a Industry/University Cooperative Research Center (I/UCRC). The North Texas Daily published an article about this collaboration HERE on February 1, 2007.

Dr. Oh Awarded NSF Grant for EMIS Project Dr. JungHwan Oh

Dr. JungHwan Oh, a new faculty member whose research focuses on medical imaging, was awarded a National Science Foundation grant for $73,708 for his project, "Endoscopic Multimedia Information." Dr. Oh is the Principal Investigator along with Wallak Tavanapong and Johnny Wong of Iowa State University and Piet C. de Groen of the Mayo Clinic in Rochester, MN.

Dr. Oh said many advances in video technology are being incorporated into current healthcare practice. Endoscopes are used for a number of formerly open surgical procedures, including resection of gallbladders, retrieval of donor kidneys, coronary artery bypass grafting and minimally invasive neurosurgeries. During an endscopic procedure, a tiny video camera at the tip of the endoscope produces a video signal inside the human body.

Video data provided during these procedures are not systematically captured for real-time or post-procedure reviews and analyses. No hardware or software tools have been developed to capture, analyze, and provide user- friendly and efficient access to the content on these videos. The aim of this project is to develop an Endoscopic Multimedia Information System (EMIS) to capture high quality endoscopy videos, analyze the captured videos, and provide efficient access to the valuable content of these videos.

Other support for this project is from the Mayo Clinic, Grow Iowa Values Fund, Iowa State Research Foundation and the University of Texas at Arlington. More information about the EMIS project can be found at Dr. Oh's faculty website:
