Awards
While more than 35% of MIT faculty members are alumni, very few have volunteered
much with the Alumni Association, according to Technology Review. In
contrast, Rafael Bras '72, '72 (SM), '75 (ScD) has worked on phonathons, served
on alumni boards, worked with class reunion committees, and traveled around to
meet many alumni groups when he was CEE department head. This autumn he will
begin a two-year term as chair of the MIT faculty, and he is already halfway
through a term as vice president on the alumni Association Board of Directors.
"Wonders of Planet Water: Complexity and order in Earth Systems" will
be Rafael Bras's topic as he delivers the 2003 Lornz Lecture at the Fall 2003
American Geophysical Union meeting in San Francisco.
The Hispanic Engineer National Achievement Awards Corp. Board of directors and
Hall of Fame Executive Committee have elected Rafael Bras a member of the Class
of 2003. The press release describes the HENAAC Hall of Fame as the Hispanic
technical community's most prestigious circle, comprised of world-class
engineers and scientists whose accomplishments are of monumental significance to
the community, the nation, and to the progress of science and technology.
Rafael Bras, the Bacardi and Stockholm Water Foundations Professor in civil and
environmental engineering, has been named a corresponding (foreign associate)
member of the Academy of Engineering of Mexico.
Two departmental awards for grad students have been announced. Brittany
Coulbert has received the Goldberg-Zoino Endowment Fund, and Jason Brown will
benefit from the Louis Berger Fellowship Fund.
Forest Flager '03 (MEng) has received the 2003 American Institute of Steel
Construction/ Structural Steel Fabricators of New England Fellowship.
Research Associate Tomer Toledo 03 (PhD) received two awards for his doctoral
thesis work. The Institute for Operations Research and the Management Sciences
(INFORMS) gave him an honorable mention in the 2003 Transportation Science and
Logistics dissertation prize competition, he received another honorable mention
in the 2002 Eric Pas Dissertation Competition in Travel Behavior Research,
awarded by the International Association for Travel Behavior Research (IATBR).
Toledo's thesis, "Integrated Driving Behavior Modeling" was supervised
by Prof. Moshe Ben-Akiva and Prof. Haris Koutsopoulos (Northeastern Univ.). The
thesis creates a fundamentally new model of driver behavior, which applies sound
behavioral principles and rigorous econometric techniques to develop a framework
and models that fully integrate all the dimensions of driving behavior. Among
other things, the models unite decisions such as acceleration, deceleration, and
lane changing. They also incorporate the goal orientation of drivers and their
planning capabilities to reach their objectives. Being able to model drivers'
behavior to a high degree of accuracy is vital to understand the workings of
transportation systems, and it impacts results of safety studies, evaluation of
facility capacity, and the development of reliable, high fidelity traffic
simulation models.

Last year, Hai Ning won a Best Paper award in Scotland. His advisor, Prof. John
Williams, reports that this year Hai has won the Best Paper in the Teaching and
Learning Session at the International Conference on Education and Information
Systems: Technologies and Applications (EISTA´03). The title is On-line Peer
Review in Teaching Design-oriented Courses.
As president-elect of INFORMS (Institute of Operations Research and the
Management Sciences), Prof. Dick Larson will spend one year in that position,
followed by a subsequent year as president and then another year as immediate
past-president. He hopes "that this professional engagement will be
synergistic with initiatives and priorities of CEE and ESD (Engineering Systems
Division)."
Richard Camilli received the 2003 New England division of SNAME (Society of
Naval Architects and Marine Engineers) Best Graduate Student Paper award for his
work with Kemonaut, an underwater vehicle designed as a platform for the NEREUS
mass spectrometer.
In November, Prof. Charles Harvey lectured in Seattle at a special section of
the American Geological Society in honor of Henry Darcy's 200th birthday. (Henry
Darcy discovered Darcy's law, which is the foundation for the study of flow in
porous media, and hence groundwater hydrology.) "My talk, 'Solute Transport
and Reaction in Groundwater,' described recent laboratory experiments we have
conducted that enable the visualization of chemical reactions during flow
through porous media, as well as computer simulations and field
experiments." The session was called Henry Darcy's 200th Birthday:
Fundamental Advancements Through Observation and Analysis.
The French National Academy of Science in Paris invited Harvey to give a talk in
September at the "Colloque sur l'Eau" about his arsenic research in
Bangladesh. He lectured on "The Arsenic Crisis on the Ganges Delta:
Hydrology, Biogeochemistry, Human Perturbations, and Human Suffering on a Large
Scale."

Publications
The complete text of The Towers Lost and Beyond, a collection of
essays on the World Trade Center collapse by researchers at MIT and edited by
Prof. Eduardo Kausel, is available online, downloadable in PDF, at http://web.mit.edu/civenv/wtc/
The downloadable full report contains eight articles that deal with the
September 11, 2001 World Trade Center (WTC) disaster and its consequences. Most
of these articles were prepared between September 2001 and February 2002, and
many were largely written in their present form in the days following the
catastrophe.
The book begins with a brief history of the Twin Towers by Prof. John Fernandez
(Architecture). Eduardo Kausel contributed the chapters, "Inferno at the
World Trade Center" and "Speed of aircraft." Prof. Tomasz
Wierzbicki (Ocean Engineering/Applied Mechanics), Liang Xue, and Meg
Hendry-Brogan wrote "Aircraft Impact Damage," and Prof. Ahmed F.
Ghoniem (Mechanical Engineering) supplied the chapter about the fires. CEE
Profs. Oral Buyukozturk and Franz-Josef Ulm discussed "Materials and
Structures." Fernandez speculated on ways to make safer skyscrapers in
"Escaping with Your Life." Disruption in many phases of business were
considered by Prof. Yossi Sheffi in "Supply chains and terrorism."
Chapter 22, "Atmospheric Electricity and Lightning" of the new Handbook
of Weather, Climate and Water (edited by T.D. Potter and B.R. Colman, Wiley-Interscience,
2003) was written by Prof. Earle Williams and W. A. Lyons.

engineer at Dartmouth College for 12 years. Survivors include his wife,
Beatrice, four children, and four grandchildren.
John Winthrop Read '40 died on Feb. 3, 2003 in Greenville, PA. After receiving
his SB, he served as a major in command of a virtually all-black battalion in
the then-segregated military. He later joined Bessemer and Lake Erie Railroad,
retiring 36 years later as general manager.
Salvatore "Tory" Martinelli '65 (SM) died on Feb. 22, 2003, in
Alexandra, VA. He was a retired US Navy Civil Engineer Corps captain who served
in Morocco, Italy and Spain, as well as around the US. After leaving the Navy,
he worked as a civil and environmental engineer. He is survived by his wife
Jill, a son, a daughter, and a sister.
Gustav Kabeschat '55, old Course 17 (Building Construction and Engineering),
died on April 24, 2003 in Pennsylvania. He had been working for Kabeschat
Construction of Wilkes Barre.
Marty Murphy '51 died on July 6, 2003. According to Technology Review,
he had resolved by eighth grade to attend MIT and immediately applied for
admission, although he wasn't enrolled until after graduating from high school.
One of his professors was Harl Aldrich '47 (SB) & '51 (ScD), who founded the
geotech firm of Haley & Aldrich. Mr. Murphy joined as the 13th employee, and
remained with the company for 35 years of designing foundations for roads and
bridges, reviewing plans, and surveying job sites for over 1500 projects.
Mr. Murphy is survived by his wife Mary, a son, four daughters, and 11
grandchildren. As the former Class of '51 president, he is greatly missed by his
fellow graduates.
Charles Terrell '51 died on July 19, 2003 after a long illness. He was 86. Technology
Review ran an extensive biography, noting how Mr. Terrell joined the Navy in
1935 and reenlisted after Pearl Harbor. After the war, he enrolled at MIT at age
30. Working as a night superintendent for Perini Construction on a large dam
project in Georgia on the Chattahoochee River, he started to buy small farms,
improving the land by planting trees, and reselling to buy more land and plant
more trees. In 40 years, he planted millions of pine seedlings in southern
Georgia. He sent photos to the Newsletter showing bucolic landscapes with trees
reflected in clear ponds on his property, and for many years he mailed Christmas
packages to this office packed with delicious fresh pecans harvested from his
land.
At his 50th reunion in 2000, the CEE newsletter reported that Mr. Terrell
"plans to plant long-leaf yellow pine trees on 100 acres. He has also been
building kennels for pets for battered women who are forced to flee to shelters
which don't allow animals, and arranging for discounts for them to keep their
pets in kennels."
Over many years of correspondence with the CEE newsletter editor, Mr. Terrell
wrote passionately about his land, the trees, and the various wildlife attracted
by the surroundings. His other favorite subject of discussion was opera,
particularly great performances he had heard over a long time span at the New
York Metropolitan Opera.
Mr. Terrell is survived by his wife Jane, a stepson, three step grandchildren, a
brother, and several nieces and nephews.
Maj. Gen. Charles Noble '48 (SM) died on Aug. 16, 2003 at age 87 in McLean,
VA. A graduate of West Point, he commanded the 1271st Engineer Battalion in
Europe during World War II, and the 288th Engineering Battalion with the
Occupational Forces. After earning his SM at MIT, he was involved in planning
the defense for Western Europe for some years. In 1954 he returned to the US and
held engineering positions in New York, Ft. Benning, GA, and Louisville, KY. As
he rose through the ranks, he served as engineer around the world. In 1971 he
was appointed president of the Mississippi River Commission.
Retiring from active duty in 1974, Maj. Gen. Noble joined the Charles T. Main
Engineering co. In Boston, and retired 10 years later as the company president
and CEO. During his career he received the Wheeler Medal from the Society of
American Military Engineers (SAME) for outstanding contributions to military
engineering in design, construction, administration, research, or development.
He received three awards of the Distinguished Service Medal and three awards of
the Legion of Merit in the Army, and he was elected to the National Academy of
Engineering in 1981.
He is survived by four children, nine grandchildren, and three great
grandchildren.
Eugene Eisenberg '43 (old Course 17, Building Construction and Engineering)
died in Boston on Oct. 13, 2003. An extensive obituary in the Boston Globe
noted that he was 81 and had played his last game of tennis three days earlier.
Graduating early under the accelerated wartime schedule, Mr. Eisenberg served in
the Naval Construction Battalions, the SeaBees, during World War II and built
airfields and docks in the Pacific. During an interview for the CEE newsletter
in 1991, he proudly showed several pictures of his wartime days in tropical
jungles, posing with the local residents.
After teaching briefly in the MIT CE Department, Mr. Eisenberg entered the
construction business and built schools and hospitals throughout New England. He
joined Linenthal & Becker, an architectural engineering firm, which
eventually became LEA when he was chairman and CEO. The company designed and
engineered more than half the buildings on the campus of Brandeis University,
near Boston. As a license examiner for the Town of Brookline (adjacent to
Boston) and a member of the Brookline Building Commission, he oversaw the
renovations all over the city. In his CEE newsletter interview, he proudly
pointed out that he had directed the renovations for the elementary school where
the editor's children were currently enrolled, and which his wife had attended
decades earlier.
Mr. Eisenberg is survived by his wife, Shirley (Helman), two sons, a daughter, a
brother, and four grandchildren.
Mr. Jiro Adachi '53 (SM, CE) of Eagan, MN, formerly of Cambridge and Sudbury,
MA died on October 19, 2003. During World War II, he served with the US Army
Military Intelligence Service, and immediately following the war was a civilian
engineer with the Army in Japan. In 1986, after a 30-year career in structural
mechanics with the Army Materials and Mechanics Research Center in Watertown,
MA, he joined the MIT Industrial Liaison Program as an Officer, remaining until
he retired in 1996. A lifelong sports and fitness enthusiast, he was a volunteer
referee and coaching assistant with the MIT Women's Ice Hockey program
throughout the 1980s and early 1990s. He leaves his wife Eldora, a daughter and
a son, and his wife's children and grandchildren.

MIT tuition hike
With the latest 4.9% hike, MIT's tuition and fees for the 2003-2004 academic
year will total $29,600. Since MIT is committed to its principles of need-blind
admissions, financial assistance for undergraduates next year will total nearly
$70 million, with almost $59 million in the form of grant and scholarship
assistance. Almost 80 percent of undergraduates receive some form of financial
aid, and about 53 percent will receive an estimated average MIT scholarship of
$21,000.
Students receiving financial aid share in meeting the costs of their education
through self-help, or student loan and term-time work expectation. "Our
self-help level of $5,500 ensures that undergraduates can participate fully in
the academic, extracurricular and social life at MIT without carrying an undue
burden of term-time work or debt after graduation," said Elizabeth Hicks,
executive director of Student Financial Services.
Statistics for the Class of 2007, as printed in the Aug. 27 Tech Talk,
show that 40% of the 559 men and 461 women were high school valedictorians and
91% were in the top 5% of their class. They come from 49 states, DC and three
territories, plus 46 other countries.
Publicity
The MIT News Office reports that a group from MIT was among three
international scientific teams which announced the genetic blueprints for four
closely related forms of tiny photosynthesizing organisms, which numerically
dominate the phytoplankton of the oceans. The work is described in the August 13
online issues of Nature and the Proceedings of the National Academy of
Sciences.
A better understanding of phytoplankton, which play a critical role in the
regulation of atmospheric carbon dioxide as well as forming the base of the food
web, will aid studies on global climate change. Further, the metabolic machinery
of these single-celled organisms could serve as a model for sustainable energy
production, as they can turn sunlight into chemical energy.
"It behooves us to understand exactly how, with roughly 2,000 genes, this
tiny cell (Prochlorococcus) converts solar energy into living biomass,"
said Sallie (Penny) Chisholm, the Lee and Geraldine Martin Professor of
Environmental Studies in CEE and the Dept. of Biology. "These cells are not
just some esoteric little creatures. There are some 100 million Prochlorococcus
cells per liter of seawater, for example." Chisholm was part of the team
that first described Prochlorococcus in 1988.
Raymond Orbach, director of the Dept. of Energy's Office of Science, which
funded part of the research, said, "While many questions remain, it's clear
that Prochlorococcus and Synechococcus play an immensely significant role in
photosynthetic ocean carbon sequestration." In addition, Synechococcus, a
co-inhabitant of ocean waters with Prochlorococcus, has a unique form of
motility.

explain to today's students what he is doing? (Photo: MIT Museum) |
The work of all three teams "will allow us to better understand what
differentiates the ecology of these closely related organisms through
comparative genomics," said Chisholm. "We still don't know the
functions of nearly half of these organisms' genes. We're excited about
unveiling those functions‹particularly for those genes that are unique to the
different strains‹because they'll alert us to key factors important in
regulating marine productivity (photosynthesis) and plankton diversity. The idea
is to let the organisms tell us what dimensions of their environment are
important in determining their distribution and abundance. And this will become
easier and easier as the genomes of additional strains are sequenced, and the
functions of the genes are understood."
This research was sponsored by the Dept. of Energy, with additional support from
the Seaver Foundation, the National Science Foundation, the Israel-U.S.
Binational Science Foundation and FP5-Margenes. The work is part of the MIT
Earth Systems Initiative, of which Chisholm is a co-director. Data from ESI will
ultimately help monitor the planet's vital signs, predict the effects of future
human activities and otherwise contribute to responsible stewardship of the
planet.
In addition to Chisholm, MIT authors from CEE on the Rocap et. al. Nature
paper are graduate student Maureen Coleman, postdoctoral associates Zachary
Johnson and Debbie Lindell, and postdoctoral fellow Erik Zinser.
The Urban Transportation Monitor for May 2, 2003, reports that the US
Dept. of Transportation's Volpe National Transportation Center will award MIT a
contract for technical support to implement the DynaMIT model at the Los Angeles
Dept. of Transportation. The pilot project will test the application and
viability of automatic nonrecurring congestion detection and traffic management
of the integrated system.
DynaMIT will determine the baseline normal traffic condition. Once the normal
condition has been set, other systems will be used to determine the occurrence
of an incident. After the incident is detected, DynaMIT will assess the impact
and provide predictive traffic information and guidance for implementing
proactive traffic management strategies to mitigate the congestion.
The key to DynaMIT is its detailed network representation, coupled with models
of traveler behavior. Through an effective integration of historical information
databases with real-time inputs from field installations, DynaMIT efficiently
estimates network conditions, predicts network conditions in response to various
traffic control measures and information dissemination strategies, and generates
traveler information to guide drivers toward optimal decisions. The system
incorporates unbiasedness and consistency into its core operations to guarantee
that the information provided to travelers is based on the best available
knowledge of current and anticipated network conditions. Consistency ensures
that DynaMIT predictions of expected network conditions match what drivers would
experience on the network.
For more information about DynaMIT, contact Prof. Moshe Ben-Akiva at mba@MIT.edu
or 617-253-5324.

Further reading
Even as the August 2003 blackout drained New York City of electricity and
subsequent subway transportation, refrigeration, and computer power, the city
never lost its water supply. Two main tunnels provide the city with most of the
1.3 billion gallons of pure water it consumes each day, 90% streaming downhill
through aqueducts built more than a century ago. To ensure that critical supply,
a third tunnel has been under development since 1969 but is not expected to be
complete until 2020. Politics, contract disputes, municipal patronage and
corruption, and "Not In My Backyard" opposition have added years to
construction.
The New Yorker magazine describes the fascinating history and progress of
the job in "City of Water" in the Sept. 1, 2003 issue. Besides talking
to many of the sandhogs (tunnel diggers) who are currently blasting the tunnel
in lower Manhattan, author David Grann accompanies a third-generation worker
underground and graphically describes the atmosphere and attitudes of the men
involved.
Before the first water tunnel brought reliable clean water to the city in 1842,
Manhattan suffered from uncontrollable fires and waterborne diseases, including
cholera. Under appalling conditions in the 1800s and continuing to 1917, the
most desperate workers willing to undertake such risks constructed the elaborate
water system which serves the city today. Repairing deteriorating parts of the
tunnels is often impossible, leading to fears that an accident or terrorist
attack could suddenly dry out the city before the third tunnel can be finished.
The author deftly deals with all aspects of a major city's water supply, from
political combat in government to the men blasting tunnels almost 600 ft (183 m)
below the traffic. |
