Saraju P. Mohanty earned his Bachelor of Technology
degree in Electrical Engineering from the College of Engineering
and Technology, Orissa University of Agriculture and Technology,
Bhubansewar, India in 1995. He received a Master of Engineering
degree in Systems Science and Automation from the Indian Institute
of Science, Bangalore, India in 1999. He earned a Ph.D. in
Computer Science and Engineering from the University of South
Florida in 2003.
He has published several research papers in areas
of VLSI design automation, VLSI design and digital watermarking.
His paper was nominated for the best paper award at an international
conference on VLSI Design in 2003. In 2002 and 2003, he
received a certificate of recognition from the Provost of the
University of South Florida for outstanding teaching. His research
interests include high low power synthesis, VLSI CAD for DSM regime,
low power ASIC design, and dynamic power management. Dr. Mohanty's
faculty website is located at http://www.cs.unt.edu/~smohanty.
Language and Information Technologies Laboratory
Rada Mihalcea is an Assistant Professor in the Computer Science and
Engineering Department. She is one of the members of the Language and
Information Technologies laboratory at the University of North Texas. Her main
research area is Natural Language Processing, with research interests in
lexical semantics, minimally supervised natural language learning, and
multilingual natural language processing.
She is currently involved in a
number of research projects, including word sense disambiguation, shallow
semantic parsing, (non-traditional) methods for building annotated corpora
with volunteer contributions over the Web, word alignment for language
pairs with scarce resources, and graph-based ranking algorithms for
language processing. She has published more than fifty papers in
international journals and conferences, and her research is supported by
the NSF 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
"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 http://secnet.unt.edu/hospitalSurvey.
Dr. Dantu is in the process of compiling the data. For more information about

Timothy Roden Presents Paper at International Conference on
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
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.
