NSF Awards Grant to Dr. Kathleen Swigger
The National Science Foundation has awarded $499,252 to
Dr. Kathleen Swigger to study the performance of
student work teams in four countries as the teams write software.
The project will create curriculum materials to teach students
the best ways to work more effectively in global software teams.
The students working on this project will be from UNT, Panama,
Great Britain, and Turkey.
Dr. Swigger said, "Outsourcing is not going to go away. There is
a growing need to ensure that computer science students are
taught the necessary skills to deal with this new type of
programming. Students need to know how to use technology to work
in culturally mixed and geographically distributed work teams,
because distributed software development is becoming the norm."
Dr. Swigger says her research will have implications for
geographically distributed collaborative learning teams in
general, and furthers UNT's reputation as a student-centered,
public research university. She adds the project has drawn
interest from several major DFW employers. "Travelocity, Boeing,
and Lockheed Martin do similar projects at their companies, and
they are acting as advisors on the project."
Dr. Saraju P. Mohanty Receives NSF Research Grant
Dr. Saraju P. Mohanty received a NSF research-grant to support
his research in nanoscale CMOS modeling and estimation. The project
titled "A Comprehensive Methodology for Early Power-Performance
Estimation of Nano-CMOS Digital Systems" will span over three years,
2007-2010. The primary goal of this project is
to facilitate the estimation of power and performance of digital
systems described in MATLAB/Simulink when constructed using nano-
The research will result in the development of new building
blocks, collectively grouped as a new MATLAB toolbox, called
Power Box. Power Box will be fully parameterized for power and
performance to facilitate fast modeling and estimation of
systems. The proposed research involves the design and
development of theory, algorithms, implementations, and
experiments, with sufficient scope for education and training of
undergraduate and graduate students in VLSI design and system
This project can effectively serve the large, complex, digital
system design and simulation community of researchers, in both
academia and industry to boost further research and to reduce
design cycle time.
Dr. Buckles and Dr. Yuan Collaborate on Grants
Dr. Bill Buckles and Dr. Xiaohui Yuan were awarded a National
Science Foundation grant of $75,000 for a project that will map
the effects of flood damage. Their project, "A New Tool for
Economic and Environmental Planning: Expanding the Boundaries of
LiDAR," will use LiDAR, or "light detection and ranging," to
create a 3D image of varying terrain to predict the path of
floodwater during hurricanes and other floods.

In addition, Dr. Buckles and Dr. Yuan were awarded a supplemental
grant for a collaborative project with researchers at the Hefei
University of Technology of China. This project is sponsored by
both the NSF and the National Nature Science Foundation of China
(NSFC). They were awarded $49,800 by the NSF and the Chinese
partner was awarded ¥50,000 by the NSFC.
This supplemental project will focus on extending their results
to the visualization of the city model and the simulation of
disaster scenarios, such as flooding. During this project, Dr.
Buckles and Dr. Yuan expect a visit from their Chinese partner in
the middle stage of their research. During the later stage of
the project, Dr. Buckles and Dr. Yuan plan to visit their
partners in China for discussion and result integration.

Software Development Partnership Expands with NSF Grant
The National Science Foundation has awarded a $10,000 planning
grant to allow UNT to expand its current partnership in a Net
Centric Software Consortium. Dr. Krishna Kavi is the Principal
Investigator and the initial director of the Net Centric software
consortium that was established with the four major universities
in the Dallas-Fort Worth area.
The current partners are the University of Texas at Dallas, the
University of Texas at Arlington, and Southern Methodist
University. UTD and SMU also received $10,000 from NSF to
collaborate with UNT as well as Arizona State University,
University of California at Irvine, and Southern Illinois
University to form an Industry/University Collaborative Research
Each university partner has one year to recruit at least five
industrial members, paying annual membership dues, before the
I/UCRC can be established. The universities in the Dallas-Fort
Worth area will concentrate on developing high-quality software
for new generation applications that involve systems on a network
(Net Centric systems). The US Department of Defense has
expressed strong interest in the research.
Dr. Kavi says, "We are inviting about 200 companies here in the
Dallas-Fort Worth area to join the consortium. In February 2008,
a meeting will be held to explain the I/UCRC concept, benefits
for industry and how they can join the center. In short, by
joining the consortium, industry will have royalty-free access to
the research we are conducting in the center."
Dr. Kavi predicts the consortium will be known as a leading
research alliance in the United States, conducting significant
research projects for the federal government and industrial
customers and attracting the best research faculty and students
from all over the world. The consortium will also help in
creating a trained workforce to meet the needs of US industries.
