Chairman's CornerWe welcome Richard Superfine and Sean Washburn of the Department of Physics and Astronomy at UNC-Chapel Hill to our faculty as adjuncts. Both already have a long association with our department, as advisers and directors of our graduate and undergraduate students, and as principal or co-principal investigators on grants.
John Eyles and John Poulton became adjuncts in December. During the past two years, both were on off-campus assignment while they worked at Velio Communications, Inc., and both chose to stay full time with the company at the end of that period. Velio designs innovative signaling and switch-fabric integrated circuits.
We are sorry to say goodbye to James Coggins, former associate professor, who has joined NetIQ Corp. in Research Triangle Park, N.C. James had been with us since 1986 and had served six years as associate chairman for academic affairs. We wish him well in his new endeavor.
Several of our students recently received awards and honors. See inside for details.
Many thanks to all of our faculty, staff, and students who in December generously donated canned goods and money to help needy families in Orange County. I was able to deliver 20 bags of groceries to the Inter-Faith Council for Social Service in Carrboro. Administrative manager Katrina Coble, who organized the donation effort, collected enough $30 donations to feed 12 needy families. Thanks to all for your generosity during the holiday season to help the less fortunate.
Spring has arrived in Chapel Hill; truly one of the most beautiful times to be here. Please visit us if you have the chance!

To address the problem, graduate student Felix Hernandez Campos (M.S. 2001) is creating a framework of application-class models, in which each class is distinguished by the common paradigm of how it is a source of network traffic. For each class, he is creating a single stochastic model to reflect the aggregated characteristics of all TCP applications that are members of that class. The researchers hope to represent a very large number of applications with a relatively small number of class-based models because--given this set of models and the desired proportion of each class--one can generate synthetic traffic for network simulations with an arbitrary mix of applications. In his research, he is collaborating with Andrew Nobel, associate professor of statistics.
Whitaker Foundation Funds Surgical Simulation System
Stephen R. Aylward (Ph.D. 1997), assistant professor
of radiology and adjunct assistant professor of computer
science, is the principal investigator on a new three-year
grant, "Vessel Visualization and Quantification for
Partial-Organ Transplant Planning and Evaluation," funded
by the Whitaker Foundation. The goal of the project is to
develop a surgical simulation system that will help with
planning partial liver transplants between a patient and a
living donor related to that patient; specifically when
both donor and recipient are adults. Donations from living
parents to their children have been extremely successful,
but adult-to-adult transplant surgery has been much more
difficult for the donor to tolerate since the survival of
an adult recipient relies upon a larger graft donation than
that required for a pediatric recipient. Studies show that
30 to 67 percent of livers have anomalous hepatic vascular
anatomy. Because reviewing 2D slices of MR or CT scans is
often insufficient to detect these anomalies, Aylward and
his colleagues are developing software that will allow a
surgeon to interactively visualize 3D models of a liver's
vascular network based on MR and CT scans; to analyze them;
and to specify a surgical path through them in 3D. The
software will also help the surgeon to predict the outcome
of a potential transplant. Researchers hope that surgeons
also will be able to use the system to plan many other
minimally invasive procedures that are driven by an organ's
vascular network, such as partial-lung transplants, liver
lesion ablations, and brain tumor resections.

New Tele-Immersion Project to Train Surgeons
Researchers at UNC-Chapel Hill and Brown University are
collaborating on a new project to develop tele-immersion
technology for training surgeons. Andries Van Dam,
professor, of Brown is principal investigator and
Gregory F. Welch (Ph.D. 1997), research associate
professor, of UNC-Chapel Hill is co-principal investigator
on the project, "Electronic Books for the Tele-Immersion
Age: A New Paradigm for Teaching Surgical Procedures,"
which received one of the National Science Foundation's
competitive Information Technology Research awards.
Henry Fuchs, Federico Gil professor, and Herman
Towles, senior research associate, are also
participating at UNC-Chapel Hill. Colleagues from the
University of Pennsylvania will also collaborate
indirectly. The project will involve both computer
scientists and medical professionals and will build on
prior work by the computer scientists.
The researchers recognized that with the dramatic increase in the pace of surgical innovations, mechanisms for training and re-training surgeons on the new methods have become inadequate. The limitations of traditional videotaped instruction make it an ineffective training tool, but having the surgeon actually observe the new procedure is often not practical. They envision an immersive "time machine"; a virtual environment that allows the trainee to walk freely and naturally around a life-sized, high-fidelity, 3D graphical reconstruction of a past surgical procedure, pausing or stepping forward or backward in time to satisfy curiosity or allay confusion. The environment would incorporate commentary from the original surgeon or another instructor, integrated 3D illustrations, annotations, and relevant medical metadata. Although they are concentrating on trauma surgery, the researchers envision many other possible applications for the technology. (www.cs.brown.edu/research/graphics/research/itr/#eBook)

nanoManipulator Team Goes Back to School
In February, nanoManipulator team members spent a week at
Orange High School in Hillsborough, N.C., conducting
instructional workshops for approximately 120 students.
Students listened to presentations by scientists, learned
about the nanoscale science at the heart of the project,
and used the nanoManipulator to experiment with viruses.
Each student had the opportunity to interview two of the
scientists or computer scientists on the team, which
consisted of UNC-Chapel Hill faculty and students in the
departments of Computer Science and Physics and Astronomy,
the School of Education, and the Curriculum in Applied and
Materials Sciences. Team members looked at the impact on
the students of using the nanoManipulator across a live
Internet connection to the Atomic Force Microscope,
compared to using saved stream files. They also
investigated the impact of haptic feedback on students'
conceptions of viruses.
This visit was the latest of several that the nanoManipulator team has made to Orange High. Past visits have shown that the project has been successful in increasing students' interest in science, and their understanding of various fields of science and what scientists do. Students have reported enjoying the chance to meet and interact with UNC-Chapel Hill faculty and students. (www.cs.unc.edu/Research/nano/)
The 22nd Annual IEEE Real-Time Systems Symposium (RTSS)
took place in London, England, in December 2001. RTSS is
the premier technical conference for real-time systems
research. Kevin Jeffay, S.S. Jones professor, was
the general chair of the conference. The program committee
included Jim Anderson, professor, Sanjoy
Baruah, associate professor, and Giuseppe
Lipari, a former visiting graduate student at
UNC-Chapel Hill, who is currently on the faculty at Scuola
Superiore Santa Anna in Pisa, Italy. The IEEE Technical
Committee on Real-Time Computing gave Jeffay an IEEE
Service Award, in recognition of his services to the
real-time systems community.

Several papers had UNC-Chapel Hill links. Graduate student Shelby Funk (M.S. 2001) presented "On-Line Scheduling on Uniform Multiprocessors," co-authored with her adviser, Baruah, and former departmental visitor Joel Goossens. Graduate student Phil Holman presented "Guaranteeing Pfair Supertasks by Reweighting," co-authored with his adviser, Anderson. Bjorn Andersson, a student at Chalmers University in Sweden, presented "Static-Priority Scheduling Upon Multiprocessors," co-authored with Baruah and Jan Jonsson (also of Chalmers). Both Lipari and Gerardo Lamastra, who visited UNC-Chapel Hill for several months during 2000 and who is currently at Telecom Italia, also presented papers.
RTSS 2002 will be held this December in Austin, Texas. Baruah will chair the program committee, which will once again have a significant UNC-Chapel Hill presence. (www.cs.unc.edu/~baruah/Meetings/2002-RTSS/)

Students majoring in computer science will receive rigorous training in the foundations of the field and related mathematics, with ample opportunity to specialize in software systems, programming languages, theoretical computer science, or applications of computing technology in science, applied mathematics, medicine, or business. Students will be required to take a sequence of courses in computer science as well as in related disciplines including mathematics, physics, and statistics. According to Kevin Jeffay, S. S. Jones professor and director of undergraduate studies, the new major will offer new courses and has the flexibility to respond to changes in the field over time.
Currently about 30 juniors and seniors are enrolled in the new major. Although the size of the program may grow over time, Jeffay said that the department will always foster a sense of community among undergraduates, graduate students, and faculty, including one-on-one mentoring relationships; a distinct advantage over an undergraduate computer science program at a large engineering school.
To gain admission to the major, students must obtain a grade of C or better in the core courses in physics, mathematics and computer science. To graduate with a B.S. in computer science, students must achieve a C average or better in all junior/senior courses, and receive no grade lower than a C- in any of these courses.
In addition to taking classes, undergraduates can participate in many departmental and university activities. They may enhance their learning experiences by joining one of the department's research projects, or pursue self-directed research with a faculty member. They can also serve as lab assistants or teaching assistants for computer science courses, or gain valuable work experience as assistants on the Computer Services staff. Activities, such as the annual ACM programming contest (see article below), give students the chance to test their skills and knowledge against their peers at other universities.
Previously, students interested in computer science selected the computer science option offered by the Curriculum in Mathematical Sciences. The mathematical sciences major is being phased out and is being replaced by the computer science major and by a new program in decision sciences being offered by the departments of Operations Research and Statistics.
For more on the new major, see: www.cs.unc.edu/Bachelors/.
ACM Programming Contest
Two teams of undergraduates from UNC-Chapel Hill competed
in the regionals of the annual ACM Programming Contest last
fall and one team made it all the way to the finals this
spring. John Ehrhardt, Derek Hartman, Nate Massey, Chris
Schenck, Mike Trinh, and Matt Vross competed in
the Mid-Atlantic USA Programming Contest in Durham, N.C.,
in November. The team of Ehrhardt, Massey, and Schenck,
placed sixth, earning them a trip to the ACM International
Collegiate Programming Contest World Finals, held in
Honolulu, Hawaii, in March, along with 63 other regional
championship teams. Trinh accompanied them as an alternate,
and professors Kevin Jeffay and Ketan
Mayer-Patel went along as coaches. To win the joint
ACM/IBM-sponsored contest, teams from all over the world raced
against the clock to solve nine complex, real-world
problems in five hours. Although a team from Shanghai
JiaoTong University were the ultimate contest winners, the
UNC-Chapel Hill contestants did receive an honorable

Don't let the legislators in Raleigh hear that associate professor Anselmo Lastra taught his First Year Seminar students to build robots out of Lego Mindstorm kits and RCX computers: it sounds like a little too much fun for students to be allowed to have. But in order to build those robots, the students taking the course, "What's under the Covers? A Hands-On Introduction to Computers" in fall 2001, did learn some principles of computer operation and about the craft of design. They put their new knowledge to the test by designing and building two different robots: one for the midterm project competition and one for the final.
BattleBots: Lego Style
For the midterm competition, students had to design autonomous robots that would sweep a playing field clear of obstacles (eight empty coke cans). The robot that could clear the field in the shortest amount of time was the winner. Louie Padgett won first place with his robot, Zeus' Chariot, which was so fast that it cleared the cans in five seconds. The final contest was played on a mock soccer field with two goals. Robots had to get the maximum number of ping-pong balls (painted black and distributed randomly) into a goal in three minutes.

As in previous years, during 2001 and early 2002, we received a lot of press coverage. Areas attracting the most interest include augmented reality surgery, the dAb haptic painting system, digital mammography (part of the work of the Medical Image Display and Analysis Group [MIDAG]), image-based rendering, the nanoManipulator, tele-immersion, and walkthrough.
In the Media
Our recent and upcoming print appearances include articles in Computer Graphics World, Das Compaq Magazin, Discover, The Economist, IEEE Computer, Mechanical Engineering, MIT Technology Review, Popular Science, Scientific American, and Wired, among others; as well as in two publications produced at UNC--the Carolina Alumni Review and Endeavors--and in several on-line publications. Newspaper coverage has ranged from local dailies, such as the Chapel Hill News, the Herald-Sun of Durham, and the News & Observer of Raleigh, to national and international papers including The New York Times, The Guardian (England), The Star (Canada), and Suddeutsche Zeitung (Germany).
Broadcast coverage of our research has included a February 2001 interview with Leandra Vicci, MSL director, about her patent for an automatic emergency warning device and GPS position indicator, which aired on the local NBC affiliate's evening news; and a nationally broadcast CBS Evening News segment in December 2001 on digital mammography, which featured MIDAG member Etta Pisano, M.D., of the Department of Radiology. Our nanoManipulator work appeared in Springboard, a PBS show airing in April 2001 in the San Francisco area. A three-part BBC television series, The Virtual World, broadcast in March and April 2002 in the United Kingdom, featured several of our research projects, including augmented reality surgery, effective virtual environments, nanotechnology, and tele-immersion. An upcoming documentary about nanomedicine being produced for the Discovery health channel will include footage of our nanotechnology work. WGBH-Boston is also featuring nanotechnology in the pilot for a new show, tentatively called Nova: Leading Edge.

Operating System Upgrades
John Sopko, UNIX systems manager, upgraded the
operating system on our Suns to Solaris 2.7. Murray
Anderegg (M.S. 1991), Linux and e-mail systems
administrator, upgraded our Linux systems to Red Hat
version 7.1. Charlie Bauserman, PC systems
administrator, upgraded the majority of our PC systems to
Microsoft Windows 2000 and Office 2000. These upgrades are
needed to keep up with the latest hardware and software and
to get needed security patches.
Remedy System Improvements
After shifting from our homegrown Problem System to the
Remedy System in December 1999, we developed methods to
separate user-logged tickets from those logged by Computer
Services staff, in order to deal with user issues more
quickly. Remedy also escalates the priority of issues as
they age and allows us to close tickets twice as quickly as
before, cutting our backlog by 80 percent.
Improved Video Class Facilities
In 2001, network coordinators David Musick and
David Harrison rewired the control room for the 011
classroom, set up an AMX control system, and replaced the
Alka-Seltzer tablet lights in the room with canister
lights. They also set up the 014 classroom for videotaping
Upgraded Dial-in Service
John Sopko and David Musick replaced our old
terminal server with one capable of 56-kilobit connections.
The new system also provides a simpler dial-in interface
and a single number for both PC and Mac users.
