In This Issue
Chairman's Corner
Fall is hurricane season in North Carolina. In September, Hurricane Floyd swept across the eastern part of our state. The accompanying rain caused widespread flooding, resulting in a great deal of damage. Luckily, the Chapel Hill area was spared. We were not so lucky four years ago, however, when Hurricane Fran visited us at the start of the fall 1995 semester.I am sorry to report that the UNC-Chapel Hill community lost its chancellor, Michael Hooker, 53, to cancer in June. He had been diagnosed in January with non-Hodgkin's lymphoma. During his four years as chancellor, he worked tirelessly on many issues. He was a strong advocate of the increased use of technology in education. Michael was a great friend to this Department and we will miss him.
We are also very sorry to announce that Gyula Mago, professor, has retired after 29 years on our faculty. We will miss Gyula and wish him well in his retirement. We will hold a party for him later this fall.
On a happier note, we welcome three new faculty members to our ranks. Sanjoy Baruah, associate professor, joined us in July. Jack Snoeyink, professor, joined us in August. See below for more about them. Ketan Mayer-Patel will join us as an assistant professor in January, after receiving his Ph.D. from the University of California at Berkeley. Look for more about Ketan in our Winter issue.
We also welcome a very large entering class of new graduate students: 45 in all. We welcome back all our returning graduate students and undergraduate students in Mathematical Sciences.
Congratulations to Siddhartha Chatterjee who has been promoted to associate professor with tenure, effective 1 January 2000. Congratulations also to Tim Quigg, lecturer and associate chair for administration and finance, who is one of four recipients of the 1999 Chancellor's Award for Excellence.
We held a day-long departmental retreat in May to discuss a number of issues: the proposed undergraduate curriculum, the graduate curriculum, research directions, and faculty recruiting. We had many productive discussions and will continue our planning with additional retreats and meetings in the year ahead.
We will announce the recipient of our Alumni Fellowship in our Winter issue. Generous support from our alumni and friends helps make the Alumni Fellowship possible. You have been so generous in the past, and we hope you will continue to support us.
We hope you will visit us if you are in the Chapel Hill area. Or visit us virtually, via our Web pages, for the latest news and information about us.

Welcomes and Farewells
Sanjoy Baruah, associate professor, Ph.D. 1993, Texas-Austin. Scheduling theory; real-time and safety-critical system design; computer networks; resource allocation and sharing in distributed computing environments.
Prior to coming to UNC-Chapel Hill, Sanjoy was an assistant professor in the Computer Science Department at the University of Vermont. He joined Vermont after receiving his Ph.D. in 1993 from the University of Texas at Austin. He did his undergraduate work at the Indian Institute of Technology in Delhi, India, where he was a classmate of Dinesh Manocha, associate professor.
Sanjoy's research interests and activities concern feasibility-analysis and fairness issues in shared-resource systems. Currently, he is working to develop new techniques for the formal specification and analysis of real-time safety-critical application systems, and to design strategies for fair bandwidth allocation in computer networks.
Jack S. Snoeyink, visiting professor (effective July 1999; professor effective 1 January 2000), Ph.D. 1990, Stanford. Computational geometry; geographical information systems; geometric modeling and computation; algorithms and data structures; theory of computation.
Jack joins us from the University of British Columbia (UBC) where he was an associate professor in the Department of Computer Science. He received his Ph.D. from Stanford University in 1990, then spent a year as a postdoctoral researcher at Utrecht University in the Netherlands, prior to joining UBC in 1991.
His research in computational geometry has two interrelated foci: first, on algorithms and data structures for discrete geometry, and second, on practical applications of geometric computation in Geographic Information Systems (GIS). In the first, his objective is to understand the nature of geometric computation by solving geometric problems that have been abstracted from some application area (GIS, robotics, solid modeling, databases). In the second, he is working to obtain robust implementations of data structures and algorithms that open up new capabilities for GIS.
Jack is accompanied by three students from UBC. Hamish Carr is working with Jack on applications of Morse Theory to algorithms for molecular data, Martin Isenburg is working on compression for geometric surface meshes, and Andrea Mantler is working on algorithms in computational geometry.

Philip Winston, research engineer, who left in April to join SensAble Technologies in Cambridge, Mass. He had worked with us since January 1998.
Dr. Gyula Mago Retires
This fall, Gyula Mago, professor, retired after 29 years of service. During his career here, he has been a scholar, an award-winning teacher, and an advisor, a mentor, and a friend to many students.
Originally from Hungary, Gyula received a diploma in engineering in 1962 from the Polytechnical University of Budapest, then joined its faculty as an assistant professor. He joined our Department in 1970, after receiving his Ph.D. in computer science from Cambridge University. His research interests have included computer architecture, parallel computation, and programming languages. He was one of the principal developers of the FFP machine, a small-grain parallel reduction computer that could be programmed easily and flexibly, without unduly sacrificing its performance potential. In addition to his many papers over the years, he was issued a patent, "Cellular Network of Processors" (U.S. Patent No. 4,251,861), in 1981.
Gyula has advised many master's and doctoral degree candidates. His Ph.D. advisees have included Edoardo S. Biagioni (1992), Scott H. Danforth (1983), R. Kent Dybvig (1987), David R. Kehs (1978), V. Alexis Koster (1977), David J. Middleton (1986), Roy P. Pargas (1982), William D. Partain (1989), Mark Pozefsky (1977), and Donald M. Tolle (1981).
During his time here, Gyula has taught countless students. His talent as a teacher is illustrated by the fact that he has won the Computer Science Students Association's Teaching Award two out of the five years that the award has been given: in 1996-97 and 1998-99. Nominators for the most recent award wrote, "Dr. Mago has put his unique stamp on COMP 206 [the graduate core course on computer architecture], explaining what is important, distinguishing between fact and opinion, giving his own historical perspective, and providing a much needed framework on which to hang the various facts and principles . . . . Within the handouts are tables, diagrams, rules of thumb, and new ways of looking at the material that make the course come alive . . . . But beyond the details and specifics is the big picture. Students come away from Dr. Mago's classes feeling privileged to have known a great teacher and a great human being. Dr. Mago's relentless spirit is what shines through the equations and diagrams . . . ." (www.cs.unc.edu/Info/Events/News/CSSAAward9899.html)
The Department will hold a retirement party for Gyula later this fall.
Research Highlights
Jim and graduate student Anand Srinivasan are trying to generalize the Pfair task model so that Pfair scheduling can be applied more easily in systems in which real-time tasks are not strictly periodic. They are working also to extend the current theory of Pfair scheduling to include support for interprocess communication and synchronization, I/O, and fault tolerance. Sanjoy will contribute to these efforts also. Ultimately, the researchers plan to develop an implementation of a Pfair-scheduled real-time operating system that can be used as a testbed for experimentally evaluating the algorithms developed in the project.
Computer-Aided Diagnosis Laboratory Receives Funding
Stephen R. Aylward (Ph.D. 1997), research assistant
professor of radiology and adjunct assistant professor of computer
science, recently received funding to form the Computer-Aided
Diagnosis Laboratory. The new laboratory, which will be located in
the Department of Radiology, is part of the Medical Image Display
and Analysis Group. The funding includes a portion of Stephen's
salary and funding for four computer science graduate students for
three years. Research in the new laboratory will focus on
computer-aided diagnosis of breast cancer, using digital mammograms,
and of lung disease, using chest radiographs. A significant portion of the
funding comes from the National Library of Medicine. Additional
funding comes from the Lineberger Comprehensive Cancer Center
and the Department of Radiology at UNC-Chapel Hill, and from the
Holderness Foundation for Medical Student Research Support.

Distributed nanoManipulator Demo at Internet 2 Meeting
In April, Kevin Jeffay, associate professor, Russell
M. Taylor, II (Ph.D. 1994), research assistant professor, and
graduate students Michele Clark (M.S. 1998), and
Tom Hudson (M.S. 1997) travelled to the Internet2 spring
meeting in Washington, D.C., to demonstrate the nanoManipulator
system running over Internet2. Meeting participants used the
nanoManipulator to manipulate strands of fibrin (an essential protein
in the formation of blood clots) in an atomic force microscope
located in Phillips Hall on the UNC-Chapel Hill campus. The
experiment served to demonstrate a prototype implementation of the
differentiated services architecture for Internet2 known as the
"Qbone." The differentiated services architecture for the Internet is
an attempt to provide quality-of-service assurances for the real-time
network flows generated by applications such as the
nanoManipulator. The network demonstration was a collaborative
effort between our Department, the North Carolina Networking
Initiative, and Nortel Networks.

Boeing, Air Force Interested in UNC Technology
In July, David Himmel and David Princehouse
of Boeing Corp. met with members of the Tracker project and
experimented with using the HiBall tracking system to track a
pneumatic hand drill. Boeing is particularly interested in using the
HiBall technology both to guide and to monitor hand drilling
because its new 777 jet aircraft contains approximately
one-half-million hand-drilled holes. These holes must be drilled
to very tight tolerances, both in terms of the hole position and the
angle of drilling. Currently, there are on the order of five thousand
"problem holes" that result in very expensive additional work.
Boeing is also interested in using some of the projector-based
visualization technologies that are being pioneered in UNC's Office
of the Future project. Boeing sees the potential to improve aircraft
assembly by projecting the instructions for drilling and wiring
directly onto the air frame.
Also in July, Lt. Col. Milt Miller, a technical projects director at the U.S. Air Force Research Laboratory's (AFRL) Warfighter Training Research Division in Mesa, Az., visited with members of the Tracker project to discuss the HiBall tracking system. Miller is investigating head tracking systems--such as the HiBall--that are fast, accurate, and robust in order to improve the training simulators in a night-vision simulation system for Air Force pilots. Increasingly, pilots are using night-vision "goggles" to aid in dusk or night flight, which requires special training. Miller was also interested in both the projector-based visualization technologies of the Office of the Future Project and the extremely realistic scene modeling work of the Image-Based Rendering Group.
