Chairman's CornerGreetings and a happy New Year from Chapel Hill. Our spring semester began with a record-breaking snowfall in late January. Around the Triangle area, as much as 16 to 20 inches of snow fell. The large accumulation of snow and ice forced the University to close for three days.
As many of you already know, Fred Brooks, Kenan professor, has won the 1999 ACM A. M. Turing Award. Congratulations, Fred! ACM recognized Fred for his landmark contributions to computer architecture, operating systems, and software engineering. Fred will receive the award at ACM's annual awards banquet in May. See below for more information about Fred's lifetime contributions to computer science.
I'm also very pleased to announce that Voicu Popescu is the newest recipient of our Alumni Fellowship. See below for more about Voicu's research. The Alumni Fellowship is made possible by generous contributions from alumni and friends. We thank you very much for your support.

Alumni Fellowship Winner
Voicu is working on his dissertation, "High-Quality Forward Reconstruction for 3D Warping Efficiently Implementable in Hardware," under the guidance of Anselmo Lastra, research associate professor. In recent years, many computer graphics researchers have focused on using photographic images as rendering primitives. Image-based rendering (IBR) overcomes the modeling bottleneck associated with rendering from geometric models and promises photorealism at interactive rates. Three-dimensional image warping is a very appealing IBR technique, but quality output images can be reconstructed only by sacrificing interactivity, even when the latest rendering hardware is used. Voicu has produced a high-quality forward reconstruction algorithm for 3D image warping that can be implemented efficiently in hardware. He and fellow researchers have devised the WarpEngine IBR architecture, which is based on his algorithm. Their experiments indicate that the WarpEngine will be capable of producing high-quality high-resolution images at sustained interactive frame rates.

Fred Brooks wins 1999 Turing Award
Frederick P. Brooks Jr., Kenan professor, has received the Association for Computing Machinery's (ACM) 1999 A. M. Turing Award, considered the "Nobel Prize of Computing." The award, ACM's most prestigious, is given to an individual who has made technical contributions of lasting importance to the computer field. ACM cited Fred for his landmark contributions to computer architecture, operating systems, and software engineering--contributions that have stood the test of time and shaped the way people think about computing.
ACM will honor Fred at its annual awards banquet in San Francisco, Calif., on 6 May. A $25,000 prize accompanies the award. Fred will present his Turing Award lecture, "The Design of Design," at SIGGRAPH 2000 in New Orleans, La., on 25 July.
"It is indeed a high honor to be associated with the distinguished computer scientists and great people who have won the Turing Award over the past three decades," Fred said.
Edward Lazowska, award committee chair, said, "Fred Brooks has changed the face of computing: the way we think about computer architecture, the way we engineer software and the way we use 3D interactive computer graphics to advance other fields. Beyond these extraordinary technical contributions, Fred is a true gentleman with enormous personal integrity, whose leadership has shaped our discipline in countless ways. I'm delighted that this long overdue recognition occurred on my watch."
Fred, who coined the term "computer architecture," was project manager for the development of IBM Corp.'s System/360 family of computers and Operating System/360 software. He led the team that first achieved strict compatibility, upward and downward, in a computer family. At IBM, he also was an architect of the Stretch and Harvest computers. With Dura Sweeney, he invented a Stretch interrupt system that introduced many of the features of today's interrupt systems.
Fred's early concern for word processing led to his selection of the 8-bit byte, the decision to make the byte the addressable unit, and the inclusion of a full upper- and lower-case character set. All of these concepts are now universal practice.
In 1997, Fred wrote, with Gerrit A. Blaauw, Computer Architecture: Concepts and Evolution. The book documents and exemplifies the power of their 1960's innovation of thinking about computer design as separable domains: architecture, implementation and realization. Similarly, many of the technical innovations found in OS/360--such as the approach to input/output handling, and the method of transition between supervisor and user modes--are foundations of today's operating systems.
Even more influential, though, according to ACM, is the distillation of the successes and failures in the development of OS/360 that Fred captured in his 1975 book, The Mythical Man-Month: Essays on Software Engineering. Today, 25 years, two editions, and 300,000 copies later, the book remains a defining work in the field of software engineering.
Brooks left IBM in 1965 to found our Department, which is now considered a world leader in interactive computer graphics. Here, his research on real-time, 3D computer graphics has propelled that field forward, driven by the goal of creating tools that enable scientists and engineers to tackle problems formerly beyond their reach. Fred's students built the first molecular graphics system on which a new protein structure was solved. They also first proved that haptic displays augmenting visual displays can significantly improve a scientist's understanding of data.
Fred received his undergraduate degree in physics from Duke University in 1953. He earned his master's and doctoral degrees in computer science, under Howard Aiken, at Harvard University.
The A. M. Turing Award is the latest award for Fred. In 1994, he was the first recipient of ACM's Allen Newell Award. He won ACM's Distinguished Service Award in 1987 and the John von Neumann Medal from the Institute of Electrical and Electronics Engineers in 1993. In 1995, he received the Franklin Institute's Bower Award and Prize in Science, which carried a $250,000 prize. A decade earlier, he was in the first group of engineers to receive the National Medal of Technology, presented by President Ronald Reagan. In 1986, he received UNC-Chapel Hill's Thomas Jefferson Award, which goes to a person who best exemplifies the ideals and objectives of Jefferson.
Project members will install an atomic force microscope (AFM) inside the SEM chamber. An AFM contains a tip that touches down on a surface and scans back and forth, creating a 3D picture of that surface. This type of microscope is useful in measuring physical properties such as stiffness and friction. Adding an AFM inside the SEM will allow scientists to use these microscope systems together, allowing for a wider range of experiments. Graduate student Adam Seeger will develop the software system to combine these microscopes into a single virtual instrument that will have the capabilities of both. Researchers will use the system to explore the properties of carbon nanotubes and to build and test novel nanometer-scale electromechanical systems. The SEM was purchased with funds from two U.S. Army Research Office grants, the Graduate School, the College of Arts and Sciences, and the departments of Computer Science and Physics and Astronomy.
nanoManipulator Demo in Asheville
On 6 December, Russell M. Taylor II (Ph.D. 1994), research
assistant professor, and Amy Henderson, graduate student,
demonstrated the Distributed nanoManipulator at a meeting convened
by Congressman Charles Taylor (N.C. District 11), in Asheville,
N.C. The meeting grew out of Congressman Taylor's interest in
telecollaborative science and his work with a consortium of educators
in western North Carolina to bring technology to the region and to
conduct teacher training.
The Distributed nanoManipulator demo was one of six organized by the National Coordination Office for Computing, Information, and Communications and was the only one from a North Carolina university or research institution.
Team Helps Washington, D.C., Ring in 2000
Members of the nanoManipulator Project team traveled to Washington,
D.C., over the New Year's weekend to participate in the "America's
Millennium on the Mall" celebration, which featured free
demonstrations, performances, discussions and family programs
in three Smithsonian Institution museums. Events emphasized the
passing of traditions from one generation to another. "Future Visions"
was the featured program at the Hirshhorn Museum, where the
nanoManipulator team shared the spotlight with seven other groups
from academia and private industry. Russell M. Taylor II
(Ph.D. 1994), research assistant professor, and Chris Dwyer,
graduate student, of our Department, and Richard Superfine,
associate professor, Sean Washburn, professor, and Neil
Snider, graduate student, of Physics and Astronomy, gave their
demonstration as part of the session on "Glimpsing the Future:
Technologies for the Millennium," a series of demonstrations about
new technologies that will shape lives in the next century and about the
science behind them. Their presentation illustrated how advances in
biochemistry and nanotechnology may guide future efforts to manipulate
viruses and DNA. Involving atomic-scale manipulation of biological
materials, the demo emphasized why atomic-scale research holds such
great promise both for prototyping new materials and for testing the
Students Study Viruses with nanoManipulator
In November, nanoManipulator Project team members paid a second
visit to Orange High School in Hillsborough, N.C., to allow students
to see, touch, and push viruses. This time, they scaled back the
traditional teaching component in order to give students additional
interaction time with the researchers and the equipment. Team
members conducted a controlled study of the effectiveness of haptic
feedback on the students' understanding of viruses. The team's
first visit to Orange High School was in June 1998.
CDAT will set up new companies, help inventors develop
prototypes of their ideas, and provide the financial, business, and
marketing expertise to turn the prototypes into marketable products.
Both the inventors and UNC-Chapel Hill will benefit from the
arrangement: inventors will have their research developed and
marketed; UNC-Chapel Hill will receive royalties and access to
the resulting technology improvements and products. Inventors
will retain the majority of the stock in the start-up companies,
with CDAT and UNC-Chapel Hill each owning a small
Nick and Mary Whitton, research assistant professor,
supplied the initial funding for CDAT, and Nick has been working
to secure additional investors. Nick and Mary have started successful
companies in the past and bring a wealth of experience to the venture.
Currently, CDAT is negotiating with the University for licenses
to three technologies and is forming a new company around each.
Its office is on Franklin Street, a short walk from campus, in order
to provide the easiest possible collaboration between CDAT and
researchers on campus. For more information, visit
To fill another gap between research and applications, Nick
and Mary are spearheading the formation of the Institute for
Development of Advanced Technology (IDAT), a non-profit
institute that will be able to partner with UNC-Chapel Hill
researchers. IDAT will provide the application development
and support services that funding agencies need but that do not
fit with the Department's research and educational mission.
Funding agencies will benefit by being able to test research
ideas in real applications, and UNC-Chapel Hill will benefit
from increased opportunities for research funding, plus a
speedier application of research results.
Gopi Meenakshisundaram (M.S. 1998) and Aditi
Majumder (M.S. 1999) attended ACM Multimedia '99 in
Orlando, Fla., in November, and presented their paper, "Immersive
Teleconferencing: A New Algorithm to Generate Seamless Panoramic
Video Imagery." Also attending were Ruigang Yang and
Michael Brown, who presented their paper, "Geometrically
Correct Imagery for Teleconferencing." Both papers were co-written
with Henry Fuchs, Federico Gil professor, and Brent
Seales, associate professor at the University of Kentucky
(see "Recent Publications"
Formed to Help Commercialize UNC Technology
Nick England, research professor, has founded the Corporation
for Development of Advanced Technology (CDAT) to help turn
research ideas developed at UNC-Chapel Hill into marketable
technology. Nick is CDAT's chief executive officer and is on full
time leave from the Department. He recognized the need for an
organization such as CDAT, because, although UNC-Chapel Hill
has created a wealth of world-class technology, there has been a
missing link between that research and the development of new
products and companies.
EPA Grant Funds
Software Engineering Project
David Stotts, associate professor, is the principal investigator
on a new three year, $2 million grant from the Environmental Protection
Agency (EPA). David and graduate students Jason M. Smith,
Naveen Koorakula, and others, will collaborate with researchers
at the Carolina Environmental Program at UNC-Chapel Hill, and the
North Carolina Supercomputing Center to design and produce an
architecture that will incorporate models of the environment from
such diverse disciplines as weather prediction, air quality, watershed
dynamics, biological population and health studies, and chemical
interactions. They will use an object-oriented framework to adapt
existing and future models to work with each other, allowing the
output data of one model to be fed automatically as input data to
another. They also will produce new models that are designed for
higher efficiency, reliability and error accountability. The resulting
system will be used for scientific prediction, analysis, and political
policy decision making. The researchers are working with colleagues
at EPA sites in Research Triangle Park, N.C., and Athens, Ga., on
the initial design.
Ramesh Raskar and Michael Brown attended IEEE Visualization 1999, held in San Francisco, Calif., from 24 to 29 October, where they presented the paper, "Multi-Projector Displays Using Camera-Based Registration." Ramesh also attended the Second International Workshop on Augmented Reality, held in San Francisco, Calif., from 20 to 21 October and presented the paper "Table-Top Spatially-Augmented Reality: Bringing Physical Models to Life with Projected Imagery."
CDAT will set up new companies, help inventors develop prototypes of their ideas, and provide the financial, business, and marketing expertise to turn the prototypes into marketable products.

The Department has received a second $50,000 grant from the Frances C. and William P. Smallwood Foundation to continue upgrading the equipment in the C. Hugh Holman Teleclassroom (room 011). The Smallwood Foundation funds programs, research, and scholarships in medicine, science, education, commerce, economics, industry, and the arts.
New Smallwood Foundation Grant
The initial $50,000 grant from Smallwood paid for new cameras and projection equipment, installed last year. The new equipment has improved the quality of our videotapes and broadcasts tremendously. The new grant will finance an AMX control system that will include a touch screen panel and remote controls for lights, screens, and projectors, all on a single console.
John B. Smith, professor, who is leading the committee planning the improvements, said that the new AMX system will be so user friendly that a person giving a presentation will be able to control most of the room's functions alone, instead of requiring the services of an operator in the teleclassroom's control room.
Computer Services News
The entire Computer Services staff helped prepare Sitterson Hall for
the year 2000. Staff applied patches to AFS server software, patched
or upgraded operating systems on all Suns and HPs, tested the operation
of door security systems, verified the phone system would work,
obtained patches for call accounting and voice mail systems, patched
the Legato backup system, and verified, as much as possible, that
other systems would continue to work. Since the new year began,
the Department has experienced no significant problems.
100 New Dell PCs
Jane Stine, desktop systems manager, and William
Jiang, PC systems administrator, with assistance from undergraduate
employees and other staff, installed 100 new Dell systems in Sitterson
last year. Sixty-eight of the new systems were received as part of an
Additional PC Lab
In August, staff converted room 019 into a new PC lab. Students enrolled
in courses that require special software are the primary users of the lab.
When there are no special needs, the lab is available to anyone with a
SGIs Upgraded to Irix 6.5
Duncan Riley, SGI systems administrator, upgraded the operating
system on our SGIs to IRIX version 6.5. In doing this, he established a
more consistent and supportable installation throughout the SGI fleet.
New Solaris File
John Sopko configured and installed three new dual-processor
Solaris file servers, which will be used to back up all Departmental
UNIX file server space. Nearly all of the data has been moved from
the older Sun servers to the new ones, including all home directories,
system data, and research project space.
Last year, Computer Services staff retired all 68040-processor-based
Macintosh computers (Quadras) and all but one of the DEC Ultrix
systems. Some older Sun systems (SPARC 4 and SPARC 5) and
many HP UNIX systems were also retired. Now these older computers
are retired, staff can focus on providing better support for newer
systems. The next systems to be replaced are the remaining HPs
and the older Sun desktop systems, followed by the 200 MHz Dell
