Greetings from the CSE Chairman

Dear Alumni and Friends,

Welcome to our first email newsletter. We have decided to put this together to share with you the latest news from our Department of Computer Science and Engineering here at UNT.

We have just celebrated our one year anniversary at UNT's College of Engineering, which was inaugurated in August 2003. In January 2004, we moved to UNT Research Park, the new home of the College of Engineering, at 3940 North Elm Street in Denton.

I am also pleased to report that our B.S. degree program in Computer Science was recently reaccredited by the Computer Accreditation Commission (CAC) of the Accreditation Board for Engineering and Technology (ABET).

In Fall 2004, we have 23 faculty members in our department. There are 522 students who have declared majors in Computer Science. We also have 62 M.S. students and 34 Ph.D. students in CSCI.

One year ago, we began offering a B.S. degree in Computer Engineering. I am happy to report that we now have 83 students who have declared a major in this new program

We want you to be informed about our department and we want to be informed about what you are doing. If you have information that you would like to appear in a future email newsletter or in the department's Alumni Newsletter, please send an email with the details to

If you haven't had the chance, please add your information 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.

Periodically, we will send questionnaires asking you to evaluate our degree programs and suggest improvements. This is an essential part of our process for continuous improvement of the degree programs.

Because we don't have every graduate's email address, please forward this email newsletter to any other UNT Computer Science Alumni you may know. I hope they will respond by sending their updated information to us and they can be added to our list.

I hope you enjoy hearing from us. Now we want to hear from you. Tell us your accomplishments, honors, and awards. Send us your photo. What is your favorite class memory? We look forward to hearing from you soon.

Be an active supporting alumni and a friend of CSE and UNT.

UNT To Help Hospitals Provide Better Security

Dr. Ram Dantu, Assistant Professor in the Department of Computer Science and Engineering, has prepared a survey for hospitals in the United States to assist in researching and identifying solutions for security gaps in hospitals' networks.

The survey deals with retrieving and securely archiving digital images (MRI, CAT scan, XRAY, Ultrasound, emergency unit, outpatient ward, operating room) for examination and preparation of reports using DICOM/HL7 protocols. The hospitals surveyed range in size from 100 to 1000 beds, and they perform 50,000 to one million examinations per year.

"We are pleased to report that more than 40 hospitals have participated in the survey," said Dr. Dantu. "This provides very good visibility for our department and for UNT."

The survey is located at Dr. Dantu is in the process of compiling the data. For more information about Dr. Dantu and the Network Security Laboratory, go to

Timothy Roden Presents Paper at International Conference on Entertainment Computing

Timothy Roden, Lecturer in the Department of Computer Science & Engineering, presented a paper by Roden and Dr. Ian Parberry in September at the 3rd International Conference on Entertainment Computing in Eindhoven, Holland. The paper, entitled "From Artistry to Automation: A Structured Methodology for Procedural Content Creation," describes a general methodology for building systems that create content for 3D graphics applications procedurally. Examples of such content include outdoor terrain and indoor environments. The presentation was attended by an audience of about 50 academic researchers sharing an interest in entertainment computing.

Roden, who is also a Ph.D. candidate in computer science, describes his research as foundational for the future of 3D graphics. "We are making tremendous strides in the ability of software to interactively display increasingly complex 3D scenes, mostly due to more powerful hardware," said Roden. "At the same this is happening, content creation is still being done predominantly by humans who aren't doubling their output every six months. What's needed is software to create the content and that's the focus of this research."

Roden's advisor is Dr. Ian Parberry. Parberry has written several books on game programming topics and has a decade of experience at UNT teaching game programming to undergraduate computer science students.
