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
on February 1, 2007. For more information about this consortium, go to
Dr. Oh Awarded NSF Grant for EMIS Project
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
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: http://www.cse.unt.edu/~jhoh/.
Dr. Kavi Visits Universities in Taiwan
In December 2006, Dr. Kavi traveled to Taiwan to visit several universities
and make contacts for setting up student exchanges. At National Chiao-Tung
University, Dr. Kavi met with the Dean of the College of Computing and his
former student and host, Dr. Deng-Jyi Chen.
Dr. Kavi with Professor Chin-Teng Lin, Dean of College of Computing at National
At Fu Jen University, Dr. Kavi
signed a Memorandum of Understanding on behalf of UNT for student exchanges
to take place. Dr. Kavi also visited National Taiwan University, Dong-Hwa
University, and TungHai University in Taiwan. He is exploring internship
possibilities for students visiting universities in Taiwan.
Dr. Mohanty Gives Talks in India
In December 2006, Dr. Saraju Mohanty delivered invited talks at two
prestigious institutes in India, Indian Institute of Science, Bangalore and Indian
Institute of Technology (IIT), Kharagpur. The title of the talk was "Secure
Digital Camera", an apparatus (system-on-a-chip, SoC) with standard features
of a digital camera and a built-in facility for live, real-time, low-cost,
low-power digital rights management (DRM), a concept introduced by Dr.
In addition he presented two papers at a conference in VLSI, the
international conference on VLSI design at Bangalore, India. The titles of
his talks were, "Simultaneous Power Fluctuation and Average Power
Minimization during Nano-CMOS Behavioral Synthesis" and "Metrics to Quantify
Steady and Transient Gate Leakage in Nanoscale Transistors: NMOS Vs PMOS
Perspective". These are co-authored by Dr. Mohanty and Dr. Kougianos. These
papers were selected through a double blind review process with acceptance
ratio of 31%.
UNT to Host the 2007 SW Regional Collegiate Cyber Defense Contest
The University of North Texas will host the 3rd Southwest Regional
Collegiate Cyber Defense Contest on March 23-25, 2007. In this contest,
student teams will be given pre-configured, running systems, networked into
the contest infrastructure. These systems supply a set of services to the
network, and the goals for each team are to:
- Complete various business/technical tasks ("injects") which are given to
the teams during the contest.
- Keep the services running and available.
- Keep attackers out-a "red team" of attackers will be trying to cause
trouble throughout the contest.
Points are awarded or deducted for each of the goals, and the winner is the
team that has the most points at the end of the 3-day contest. For more
details about the contest, please go to: http://www.cics.unt.edu/ccdc/. The
winner of this regional contest will receive an invitation to compete in the
national contest to be held April 13-15, 2007 in San Antonio, TX.
LIT Research Group News
The members of the Language and Information Technology group are working on
various research projects in natural language processing. Here are their
most recent achievements:
Kino Coursey's work on integrating machine learning techniques with
common-sense knowledge bases has been accepted at the Intelligent User Interfaces
(IUI) workshop on Common Sense. Kino will attend the IUI conference in
Hawaii to present his work.
Andras Csomai's work on unsupervised methods for building back-of-the-book
indexes is described in a paper that has been recently accepted for
publication by the Florida Artificial Intelligence Research Society. Andras
will present the paper in May in Key West.
Rada Mihalcea's work on a method that integrates the Wikipedia resource into
a system for automatic word sense disambiguation is described in a paper
accepted for publication by the North American Chapter of the Association
for Computational Linguistics. Rada will present the paper in Rochester in
Rada Mihalcea will also present her research (joint work with Stephen
Pulman) on modeling features of verbal humor at the International Conference
on Intelligent Text Processing in February in Mexico City. The paper
received one of the three "best paper" awards given by the conference.
Also noteworthy is the grant that Rada Mihalcea received from the
"Hispanic and Global Studies Initiative Fund" for the project "Babylon: UNT-Mexico
Collaboration for Research on Languages with Scarce Resources". This was a
competitive grant application process, with only 10 out of 38 applications
being recommended for funding. The funds will be used to support a student
exchange between the Department of Computer Science and Engineering at the
University of North Texas and the National Polytechnic Institute (IPN) in
Mexico City, and will contribute toward developing a research collaboration
between UNT and IPN.
