Dr. mark E. Law
Professor and Chair

Professor Mark Law became Chairman of the .
Department of Electrical and Computer
Engineering at the University of Florida in
August 2003. Dr. Law is an IEEE Fellow, and
is co-Director of the Software and Analysis
of Advanced Materials Processing (SWAMP)

Dr. Mark E. Law

I'm very excited about becoming Chair of the Electrical and Computer Engineering Department at the Univer-
sity of Florida. I think the Department is well-positioned to become better recognized, make significant research
contributions, and to continue our mission of outstanding education. Dr. Martin Uman has stepped down as
Chair after ably serving the Department for twelve years. He leaves the Department in very good shape and
deserves our gratitude for his role in shaping and leading ECE.

Our fall enrollments show 760 undergraduate students and 516 graduate students, making us one of the larg-
est departments on campus. We have increased undergraduate admissions standards over the last several years,
so not only do we have one of the largest undergraduate populations, we may have the best quality students on
campus. Our graduate program continues to be very attractive, as we had over 3000 applicants, of whom 116
were admitted in the fall semester.

In the last year, we have streamlined our Master's program. It is now possible to get a one-year Master's degree.
Since Master's students currently earn a premium of 20 to 25% on their starting salary compared to Bachelor's,
this is an attractive option for students. We encourage students to enroll in our dual Bachelor's / Master's pro-
gram, which allows them to count some credits toward both degrees. I expect this program to continue to sky-
rocket in popularity as industry begins to focus more and more on recruiting Master's students.

In this issue, we profile some of our newest faculty. Dr. Renato Figueiredo's work on virtual machines and grid
based computing is highlighted. Dr. Jianbao Gao is using chaos theory to develop new ways to process signals
and extract data. Dr. Jenshan Lin's work on communications circuits and devices is also highlighted. Dr. Hui-
kai Xie is working on MEMS devices for many applications. All of these faculty have joined us in the last two
years. We also feature Ken O's work on radio and antennas on chip on page 16.

We appreciate that many of you have given back to the Department in the last several years. Donated funds are
used for so many vital activities, including faculty recruiting efforts, student organization support, and reno-
vations. The Sias family has recently completed an endowment to support undergraduate student scholarships,
and such gifts are greatly appreciated and can leave a lasting legacy. We would really be lost without your con-
tinuing generosity. Please give back to help support our mission and improve the Department. Information on
how to donate is contained on the last page of the newsletter.

Dr. martin R. Uman
Department Chairman
1991~ 2003

by Mary Barbarette

Dr. Martin A. Uman

Scientist, educator, leader, and artist: all these terms
help to paint the portrait of Distinguished Professor
Martin Uman. An alumnus of Princeton University
and aptly called one of the world's leading experts
on lightning, Dr. Uman served as ECE's Department
Chairman from 1991 to 2003. He joined UF in 1971
as an ECE professor, moving to UF from the Westing-
house Research Laboratories in Pittsburgh.

The Department flourished under Dr. Uman's lead-
ership, and he leaves it poised along the continuum of
success. "I think ECE is going in the right direction,"
he says. "Research is up, funding is up, and we're
hiring a lot of good faculty. In my last year as Chair,
our rankings in US News and World Report reflect the
quality of our program: 19th among all undergradu-
ate universities and 12th
among public universities
in the US."

Dr. Uman's administrative
legacy is marked by de-
partmental growth and en-
richment of labs and facili-
ties, including expansion
into a new engineering
building. His research and
teaching career is equally a
testament to his talent, suc- "
cess, and commitment to
excellence in his field.
Dr. Uman with his hrst gradi

Dr. Uman opened UF's Lightning Research Lab soon
after joining the ECE faculty. Since then, his innova-
tions in lightning science and technology have com-
pletely transformed the way industry deals with this
powerful and often destructive force.

Based on his research and co-development of the
technique of wideband-gated magnetic direction find-
ing with Dr. E.P Krider of the University of Arizona,
in 1975 Drs. Uman and Krider co-founded Lightning
Location and Protection, Inc. (LLP), a company which
they operated until 1983. LLP developed the National
Lightning Detection Network, now owned by Vaisala,
Inc. "The present network enables us to locate practi-
cally all cloud-to-ground lightning in North America
with an accuracy of a few hundred meters," says
Uman. "One can look on
a PC and see where all
the lightning strikes are in
almost real time." This in-
vention has had worldwide
impact in how power com-
panies operate, and has
opened up new avenues of
weather research, such as
predicting the ending of
severe storms based on the
pattern of lightning strikes.
The locating system has
been documented to save
tens of millions of dollars
uate student in the 1970s. annually in early detection

of forest fires and in more efficient electric utility op-
eration. It is even used by the UF Athletic Department
to decide whether to halt practices and games, and
when to restart them.

Basic research and the protection of power lines and
aircraft are Dr. Uman's primary research interests.
He and a team of engineers conduct experiments
year-round at the International Center for Lightning
Research and Testing at Camp Blanding, FL, which
Uman co-directs with fellow ECE Professor Vladimir
Rakov. Established in 1993, this well-equipped facil-
ity is the world's leading center for lightning research,
bringing together scientists from 13 different countries
and four continents during its 10 years of operation.
Triggered-lightning experiments at the site send rock-
ets over 1000 feet into the air-higher than the
Empire State Building-to induce lightning strikes
from natural thunderstorms. One project that is funded
by Florida Power and Light tests power line equip-

and below-ground lines.

"Creativity is rooted in the fully unencumbered process of intuition acting on a strong
foundation of knowledge and discipline. It is the result of the incomprehensible power
of the human brain to sort through vast amounts of data to find relationships between
seemingly unrelated objects, concepts, observations, and experiences. It is the
paradoxical combination of unlearning and learning." -Dr. Martin Uman


Uirtual machines
by Mary Barbarette

ur. henato I-gueireao

Virtual machines (VM) are like windows into limit-
less possibility. They are the portals between the user
and computational grids, bringing to life the infinite
variety of users' computer needs. (Think of a compu-
tational grid as analagous to a generator in a factory
that provides power to the factory.) For Dr. Renato
Figueiredo, "sharing, security, flexibility, and the cab-
ality of transferring virtual machines are what make
them interesting."

IBM pioneered VM technology in the 1970s. Their
goal was to mirror a
single physical machine's d,
operating system onto
multiple computers. Each
multiple system looks
like the original OS, but
is unaware of other sys-
tems running in the same 0M o
machine. Furthermore, 1
the programs that run on
the real machine will run
on the virtual machine. In

tionally run on a grid, and
demand a lot of comput-
ing, can experience performance overhead as little as 2
to 5 percent with respect to a physical computer.

The purpose of VMs is to allow sharing. "For


example,you can have a combination of flavors of
Microsoft Windows on your VM-Windows 98,
95, Windows 2000, and Linux. All of these different
operating systems are running concurrently and inde-
pendently, and you're sharing." says Dr. Figueiredo.
This sharing is termed multiplexing, and it spans users
and resources across administrative domains. Time
is a defining function of multiplexing. "I can assign a
computer to you for one day and then take you off and
sign another user on the next day. You have the system
for a small amount of time, but you have the impres-
sion that you have
the whole system
dedicated to you,"
says Dr. Figueiredo.
SUsers not only share

t While this process
yields a fruitful
shared partnership,
it also raises the
wan question of security.

is a commercial product developed sharing on the grid,
ware. Inc. and that's part of
the problem," Dr.
Figueiredo says. "You want to share these resources in
a way so that you know you're not going to be com-
promised." In the current model, the service provider
knows who's sharing and can authorize who uses the

resources, but the user has no control over who is
sharing. Fortunately, VMs contain thousands of lines
of code and are much easier to secure than full-fledged
operating systems, which run on millions of lines of

Virtual machines are remarkably flexible. They are
not bound to a specific physical machine, nor are they
bound to a network-unless they are involved with
group computing. Furthermore, and most importantly,
VMs are transferrable.

"You can think of an entire VM as files that you can
store on a CD or DVD-ROM," Dr. Figueiredo says.
"You can see them as just another form of data."
When he transferred to Florida from Northwestern, Dr.
Figueiredo brought his website with him. "I had my
website as an entire VM-the OS, the webserver, PHP
extension, database, everything, in a VM. I just trans-
ferred it literally as a CD-ROM and I plugged it in and
it works perfectly, without any changes. The only dif-
ference is now it has a different name on the network."

This transferrability forms the basis of Dr. Figueire-
do's research. I need to transfer the VM over the
network, and I need to transfer it on demand, and fast,
as the user requests it," he says.

The typical approach to dynamic data transfer is to
restructure the applications so they can interface with
the grid. Dr. Figueiredo's approach, however, is based
upon a unique, grid-centric perspective. "I'm looking
at a fundamentally different way of sharing resources
on a grid. People have been developing these mech-
anisms that take for granted that you have a physical

In Search of Chaos
by Mary Barbarette

Dr. Jianno bao

Every so often, an engineer comes along with an eye
for the unusual. The toolbox he carries may raise an
eyebrow or incite curiosity. His methods are different,
his perspective is unique, and his results are profound.
For ECE at UF, that engineer is Dr. Jianbo Gao.

"My research doesn't belong to a standard EE prac-
tice," says Dr. Gao. His approach is centered within a
nonlinear framework, where the theories of chaos and
fractal mathematics inform his research practice.

Scientists and mathematicians began hashing out the
ideas behind nonlinearity in the 1970's, and since then
the insights provided by chaos and fractal theory have
been applied to a wide range of disciplines. Dr. Gao's
research endeavors span myriad fields, most notably
biomedical engineering and bioinformatics, telecom-
munications and net\\% king, noise, and radar engi-

Chaos, often called deterministic chaos, has a pow-
erful geometric language that offers unique perspec-
tives to complex problems. In Dr. Gao's research,
nonlinearity functions as an intelligent voice that is
particularly useful for signal detection. By using what
he calls, "simple math and new concepts," Dr. Gao has
developed a universal detection method that covers
seemingly unrelated fields. His model helps pinpoint
the start times of epileptic seizures, clarifies breaks

between words in speech recognition systems, and
identifies interesting patterns in genome sequences.

Epilepsy treatment is effective for many patients, but
severe side effects are a concern with daily medi-
cation. Even worse, patients may become drug-resis-
tant not long after treatment begins. Timely seizure
detection is therefore crucial to making medication
more effective. Dr. Gao is collaborating with ECE Pro-
fessor Jose Principe to develop novel nonlinear tools
for detecting and predicting seizures. "The method
our group has developed turns out to be more accu-
rate, simpler, and at least 10 times faster than the best
method available in the literature, and we are working
to automate it for clinical use," he says. "We have also
been working to elucidate the mechanisms of seizure
occurrence, in particular the spatial-temporal patterns
of the EEG activities right before seizures, in hopes of
finding a simple way to inhibit seizure occurrence."

Decoding the complete human genome will require
new, faster computational methods for the study of ge-
nome sequences. Conventional approaches are largely
based on statistical analysis of these sequences, but Dr.
Gao's group has been developing methods based on
nonlinear dynamics theory and fractal theory. Prelimi-
nary results indicate that his methods are able to detect
genes and other functional units along a long genome
sequence with much less computational time.

Dr. Gao uses the fable of the tortoise and the hare to illustrate one of the foun-
dational principles of fractal theory. In essence, the length of an irregular curve
changes with the measuring unit. Hence, the hare's bounding leaps make the
distance it has to cover much shorter than that of the tortoise.

"My research doesn't belong to a standard

EE practice."

Dr. Gao's investigation of noise and its effects on
dynamical systems has led him to develop an efficient
algorithm that measures the amount of noise contained
in a signal. He has also developed a powerful algo-
rithm that measures the nonlinear effects of noise on
solid state device physics.

Dr. Gao is also engaged in the multifractal analysis of

The Future

of Communications
by Mary Barbarette

Dr. Jenshan Lin

ECE warmly welcomes Dr. Jenshan Lin, an Associate Pro-
fessor in the Electronic Circuits area. He received his PhD
from the University of California, Los Angeles in 1994 and
worked extensively in industry (including Bell Labs and
Agere Systems) until joining the UF faculty in 2003.

Dr. Lin specializes in radio frequency circuit and system
design, high speed broadband circuit system design, and
their applications. "It's actually a pretty broad field," he
says. "I like to use device technologies like either silicon
or compound semiconductors that push the capability to
very high speed, very high frequency, highly integrated, for
either low power or high power applications."

Integration is the foundation of Dr. Lin's research. He
seeks to merge mobility and broadband, computers and
communication. The computer and communication in-
dustries are fueling
this integration, and
concurrently pushing
t. lhnil, '1, \Y to smaller,
lighter, cheaper, and
more functional dimen-

Consumers' needs are
also a driving force
of this technological
merger. Consumers
want the convenience
of mobile connection
while t.l\ c ini.', with
the speed and high .
functionality of broad-
band. Wireless LAN is Dr. Lin holds a silicon w
a rapidly developing Bipolar, CMOS
manifestation of this

, a

desire. "We're building an infrastructure right now, and
eventually there will be a lot of access points around," says
Dr. Lin. "We already have it in the classroom."

Small size combined with functionality is the cornerstone
of effective electronics. In this realm, Dr. Lin is currently
working on an innovative handheld device concept he
calls the Universal Wireless Assistant (UWA). The UWA
consolidates cell phone, cordless phone, high speed wire-
less LAN, GPS, PDA or Pocket PC and can even include a
health monitor or other sensors. "Why carry three or four
devices," asks Dr. Lin, "when you can just carry one?" Dr.
Lin has been collaborating with Bell Labs colleagues (now
at the University of Hawaii) and a group at Stanford Uni-
versity on a C\ 1OS direct-conversion Doppler radar chip
that monitors heart and respiration rates, making it an in-
valuable tool for the elderly. With this portable device they
could monitor their vital
signs and communicate
with doctors from home
or anywhere, without
the need of going to
a hospital or doctor's

Dr. Lin is working with
Professors Ken O and
Joe Brewer on a project
in collaboration with
Motorola and funded by
DARPA. The aim of this
endeavor is to create a
"micronode" radio fre-
quency (RF) transceiver
er next to die photos of that can be used in a
nd RF circuits. variety of applications.
(See article on page 16).

"We're kind of on the science

fiction track."

Dr. Lin notes that the RF component of communication
devices is always a bottleneck of integration, either at the
user end or within the network infrastructure. Higher inte-
gration translates into small size and lower cost. High level
integration on the user end has shown significant impact, as
cellular phones are getting smaller and smaller. However,
much work remains to improve network infrastructure.

Dr. Lin has been working on the miniaturization of wireless
base stations. Typical cell phone basestations have a hefty
price tag-more than $100,000 each. Grandiose in size,
they are located in a small house at the base of the tower.
"Our project is fueled by size and cost reduction of basesta-

in cost, 100x reduction in size," says Dr. Lin. His team in
Bell Labs successfully integrated a receiver and a transmit-
ter, and the next step is to integrate digital electronics.

Dr. Lin's multi-disciplinary research covers electronic
circuits, communications, electromagnetics, and solid state
devices. His innovative vision, however, reaches into a
novel genre of artificial intelligence. "We are kind of on the
science fiction track," he says. "Eventually the machine,

will be pow-
erful enough
to advance
humanity, or

This fascinating interplay of man and machine is limit-

Lin says. "How much privacy do we want to give up for

These challenging questions outline the frontier of Dr. Lin's

Smallest Radio!
By Mary Barbarette

Dr. Ken 0

ECE Industry Professor Joe
Brewer and Dr. Ken O, in
alliance with Motorola and
DARPA, are creating a new '
single-chip communication ,
technology called pNode
that might just be the stuff of
storybook endings-an ideal
marriage between military
instrumentation and state-of- The smart sensor is s
t e the "0" of "IN GOD WE
the-art electronics, dollar
"You have an integrated
circuit that can basically do everything," explains Dr.
O. "We're putting all of the functions usually found on
a circuit board onto a single chip. It's really a single
chip radio. There's nothing else!" Even the battery will
be directly mounted onto the chip. The goal for this
small wonder is a size of 3 mm x 3 mm x 1 mm. For a
visual representation, take out a dollar bill. The single
chip radio will fit inside the "0" of "IN GOD WE

Because of their small size, the military has a keen
interest in this IC technology. One possible scenario
of the tiny chip harkens back to Grimm's fairy tales
and the lore of Hansel and Gretel. "A soldier could
have a satchel of these things and toss them onto the
ground and surrounding brush as he walks. Then, like
the pebbles Hansel uses to find his way back home,
the little sensors could light the soldier's return path,"
explains Dr. O.

The goal is to create sensor networks that will out-


.-perform the functions of a single
sensor. "The vision is that these
radios will be able to commu-
r nicate over distances of up to 5-
I 10 meters. You have to pay some
S -penalties, right? When you build
--- such a small radio, the distance
is small. But the idea is you put
many of these things around
small, it fits into so they can communicate over
FRUST" on the one .
S o t short distances. The information
basically hops from one radio to
another to get somewhere else."
Lab experiments are yielding fruitful results, with
communication between the antennas already reaching
15 meters.

A further goal of the project is to equip the tiny radio
with some kind of sensing device. Possibilities include
temperature and pressure sensors, or microphones
and cameras. "There are some very exciting applica-
tions," says Dr. O, "such as disaster recovery." Sensors
mounted onto the walls of buildings can help locate
people in the rubble of a collapsed building. When a
building collapses from an earthquake, for example,
parts of the building fall together. Tiny sensors mount-
ed to the building's walls could alert rescue teams to
where different parts of the building are, and conse-
quently find missing people.

In another scenario, sensors that are imbedded into
bridges and buildings could measure the stress and ag-
ing levels of the structure and radio that information to
workers as they walk by.

ISilicon Microwave Intearated

Professor Joe Brewer

A key aspect of creating the single-chip radio is devel-
oping circuits that do not require an external (off-chip)
precise timing reference. Present day radios use crystal
oscillators that are separate from the radio chip. Such
oscillators and crystals are large and expensive, and
are incompatible with the pNode concept. Motorola is
working on this end of the problem.

The possible ap-
plications of this
technology are
endless, yet Dr. 0
acknowledges it's
potential harm
if it is taken in
the wrong direc-
tion. "There are
implications to
privacy. Unfortu-
nately, with any
technology there's
always the down
side and up side to
it. It's really how
you use it."

The foundation of
Dr. O's research
mission is to en-
sure the pNode
radio remains in
good hands.

bled at the tip of the imaging probe. Once inside the
body, the mirror performs very fast, high resolution
laser scanning.

"The technology we use is low coherence optical
imaging," says Dr. Xie. "The smaller the coherence
length of the light source, the higher the spatial reso-
lution, which means you can scan at a finer depth."
The mighty micromirror performs pixel by pixel
scanning, generating an image every few tenths of a
second and covering x, y, and z axes. Software enables
3D image reconstruction in real time, and aids in iden-
tifying abnormalities.

This is a crucial advancement in a field where early
detection is critical for success. As Dr. Xie notes,
"with the micromirror technology, we will not ignore
any possibility."

Micromirrors are also a valuable tool for laser scan-
ning display. Very simple, small systems can be cre-
ated with a laser source and a micromirror, with any
flat surface functioning as a screen.

Another focus of Dr.
Xie's MEMS research
is integrating micro-
mirrors with motion
detectors for opti-
cal communications.
Vibration sensors such
as accelerometers are
crucial for the high

precision "analog" optical switches in which each mi-
cromirror can steer a laser beam from one optical fiber
to multiple ouput optical fibers.

Subterranean MEMS sensors lend a hand in earth-
quake and oil detection. To detect the distance of oil
beneath the earth, explosives are set off and the sen-
sors measure the response at different locations. As
Dr. Xie notes, traditional sensors are costly and dif-
ficult to network. CMOS-MEMS sensors, on the other
hand, are smaller and cheaper, they get higher resolu-
tion, and they can communicate by themselves. "Our
ultimate goal is to make wireless sensor networks," he

Higher Education in Kuala Lampur

December 01, 2001 to cMay 6, 2002
UNITEN is located
capital city of Ku


I about 15 miles south of the
ala Lumpur (fondly known as KL)

Many asked me why I chose to go to Malaysia,
especially so soon after September 11. The main
reason was to go outside the United States for a fuller
international experience. Besides the highly developed
countries such as Japan and Singapore, there are
several rapidly developing and progressive countries
that are keen on investing in higher education, with
special emphasis on information and communication.

My host institution was UNITEN, Universiti Tenaga
Nasional, a private, for-profit institution owned and
operated by Tenaga Nasional, the largest power generation
and transmission company in Malaysia. Primarily an
undergraduate school offering degrees in engineering and
business until five years ago, it was recently elevated to
the university level. It has over 3,000 students but graduate
education is still in its infancy.

My mission was to teach an undergraduate course in fiber
optics to electrical engineering seniors and provide help in
establishing a graduate program in photonics, along with a
laboratory similar to the one I started at the University of
Florida in 1993.

I had 128 students, evenly divided
into two lecture sections. The ethnic "mW i -i
distribution in my class reflected lu li
the population distribution rather
accurately. The big surprise was the
percentage of women: a whopping i h a
40 percent! For comparison, the if
fraction is close to 15% at UFE .e

There was no laboratory associated
with the course and I had no access to any facility where I
could demonstrate any of the components or systems I was
teaching about. I lectured 3 hours per week per section and

attendance on any given day was over 90 percent.

Malaysian students in private universities are not as well
prepared for higher education as their counterparts in
public universities, where entrance exams screen out poor
students. UNITEN, like other private schools, charges
hefty tuition and admits as many students as possible to
make a profit. The faculty members are mostly young and
inexperienced. Of the few PhD instructors, almost 50% are
from other countries such as Pakistan, India, Egypt, Bangla
Desh, and European countries. Most Malaysian instructors
have no PhD or equivalent degree. Many are trained in the
United Kingdom or Australia. All are fully loaded with
courses (12-15 hours/week) and no teaching assistants are
provided in most courses.

From the beginning I noticed a profound mismatch between
my style of teaching and the students' style of learning.
Whereas I emphasized concepts and ideas, students were
interested in memorization without inquiry. Needless to
say, my scores had to be curved steeply to pass a minimum
percentage of students as required by the university rules.
Yes, UNITEN requires that a minimum percentage of
students must pass in each course! I must say I let the
administrators know of my disagreement with this policy.

Ss I enjoy teaching and it was fun
he d yin to interact with young students
of diverse backgrounds, cultures,
e an a ns and work habits. While my
Se eeis h experience has enhanced my
understanding of the deficiency
in the current system of higher
education in Malaysia, it has
also created an awareness of the need for sharing the
expertise with developing countries. I derive a great deal of
satisfaction in this achievement.


In memory Dr. Julius T. Tou

Tunerafl F omilf

Torest 'Meadows Chapef
Gainesville, TL

Today the world feels a little darker, a ".
little more somber. Today, the tempo of
the world feels like it skipped a beat. We
seem rather left behind, slightly out of sync.
There is an emptiness in the air. Today we
grieve the sad loss of my father, professor
Julius T. Tou.

My mother, my brothers and sister, and I
thank you, our friends, for coming to pay
respects to my father, to grieve with us, but
also more importantly, to celebrate his life
and to give God thanks for the gift of my father and for the hope
and promise of life eternal for him and all of us.

I always felt if reincarnation were true, then my dad would have
been a powerful Chinese general in some ancient glorious past.
He led our family like a tight ship. There was always a strict
Confucian order to family life. We had a chain of command
leading from the children to mom up to dad. Dad was the boss
and the rock of the family. Though we faced many tumultuous
times, we sailed through and overcame through dad's leadership
and direction.

My father was a prideful man, but not prideful in the bad sense.
Rather he was a man of pride balanced with humility. He was a
man of pride in that he knew he was gifted with incredible intel-
ligence and energy.

And as we all know, he used his intelligence with great produc-
tiveness. My father advanced the world's knowledge from con-
trol systems to information systems and from database technol-
ogy to vision technology to machine translation.

The academic challenges were not enough for my father. He also
had energy to spare and pursued various business endeavors, with
my mother, from starting restaurants to investing in rental units
and real estate. He provided employment for many and instilled
in them the same spirit of initiative, self-responsibility, and taking
charge of one's life that he taught his children.

In the midst of all these endeavors,
he raised a family of four putting up
with squawking clarinets, a blaring
trumpet, and the early morning bel-
lows of an accordion. He instilled in
his children a value of learning and
doing one's best. Yoda's creed of "try
not, rather do or do not do," I heard
first from my father.

My father showed us how to live the
Buddhist spirit of tenacity we heard in
the 2nd reading. Rather than sleep or waste the hour, he instilled
in us the value of seizing each moment and making the most of it,
employing our mind, body, and spirit. We were to keep one foot
in the present moment, while also looking toward and preparing
for the beyond. In many ways, my dad's ability to reinvent him-
self throughout his lifetime to make the most of every opportu-
nity, influenced my ability to reinvent myself and thus go from
engineering to Catholic priesthood.

The strange thing was I did not know much about my father's
achievements until I was in college when one of his research col-
leagues shared with me some of my father's achievements. Then
while at MIT, I came across several books and papers he wrote.
And finally, I would work with my father at his company, CITAC
Computer, Inc. and be amazed at the tremendous wealth of ideas
and knowledge that would flow from his head. There was never a
lack of new ideas to test and implement.

In all his successes, my father had an air of humility. He never
flaunted his successes. He lived a very simple life personally. He
would wear clothes that he has had for ages until the threads were
bare thin. He would drive the same car forever. From his days
struggling as a poor immigrant graduate student, he remembered
the value of money and the need to plan for the future. He was
constantly helping students and young professors. And in look-
ing toward the future, he set up a foundation to continue his spirit
of giving and helping others.

So we give thanks to God for the gift of Julius; for all the bless-

ings he has been for all of us. The good times and the bad times
with Julius, they have all borne much fruit in our lives in many
varied ways, through the grace of God. God's goodness comes
in many packages. In Julius, God's goodness came in a very un-
usual package, where the gift is all the more precious and special.

So today we come to grieve the tragic loss of Julius. Words can-
not capture the loss experienced. There is an emptiness inside
that reveals to us how interconnected we truly are with Julius and
with each other. When one is missing or one is hurt, we all feel
it. This is our true nature. Not as independent individuals each
on our own course in life, but united together as God's children,
God's family.

Biograyhy ofJ3ulius Tou,
written 6y Eredf ou

Julius T. Tou, Graduate Research Professor Emeritus at the Uni-
versity of Florida and President of CITAC Computer, Inc., died
on June 22, 2002 at his home in Gainesville, Florida at the age of

Professor Tou was born in Shanghai, China, on August 15,
1925. He grew up in China and attended Shanghai Jiao-Tong
University, where he received a Bachelor's degree in Electrical
Engineering in 1947. He came to the United States in 1949 for
graduate studies and received a Master's degree from Harvard
University in 1950 and a Doctor of Engineering degree from Yale
University in 1952.

Professor Tou served on the faculties of the University of Penn-
sylvania, Purdue University, Northwestern University, and Ohio
State University before joining the faculty of the University of
Florida in 1967, serving as a Graduate Research Professor in
Electrical Engineering and the Director of the Center for Infor-
mation Research.

In addition to his faculty positions, Professor Tou served as the
Director of Research at the Battelle Memorial Institute in Co-
lumbus, Ohio, and was the founding Director of the Institute of
Information Science of the Academia Sinica.

Professor Tou pioneered research in digital and sampled-data
control systems, pattern recognition, image understanding and
computer vision, machine intelligence, software engineering,
knowledge-based expert systems, computer-based automa-
tion, and machine translation. He invented TBS (TeleBrows-
ing System), MEDICS (MEDIcal Knowledge System), V1REC
(VIsual RECognition system), AUTORED (AUTOmatic Reading
of Engineering Drawings), APRIKS (Agricultural Knowledge
System), and CITAC (Chinese Translation Computer) and held 7
patents in the United States, the People's Republic of China and
the Republic of China (Taiwan).

To promote education and to stimulate research, he organized
the first International Symposium on Software Engineering and
edited the conference proceedings into a book entitled Software
Engineering. A prolific writer, Professor Tou has authored, co-

authored or edited 26 books and published over 250 technical
papers. He was Editor-in-Chief of the International Journal of
Computer and Information Sciences, Editor of the Advances in
Information System Science book series, and an editor of several
journals, including the Journal of the Franklin Institute, the Pat-
tern ... -: it,,i. -, Journal, and the Journal of Pattern Recognition
and Artificial Intelligence.

Professor Tou received numerous honors in his lifetime, in-
cluding election as a Fellow and Life Member of the Institute
of Electrical and Electronics Engineers, recipient of the Distin-
guished Alumni Award from Yale University, appointment as
an Honorary Professor of the Shanghai Jiao-Tong University,
recipient of an honorary Doctoral degree from Fudan University
(China), and election as an Academician of the Academia Sinica
of the Republic of China (Taiwan).

Professor Tou's interests extended well beyond academia, and
his entrepreneurial spirit led him and his wife Lisa to found TVL,
Inc. in 1975 to manage the Shanghai Garden restaurant and JLT
Development Corp. in 1982 to develop real estate, including the
Aloha Garden Apartments and Evergreen Mall office complex.
After retiring from the University of Florida in 1992, Professor
Tou founded CITAC Computer, Inc., a software company that
applied his research in machine translation to applications for
Chinese language translation and tutoring.

In addition to a full and varied career in education and business,
Professor Tou and his wife of 45 years, Lisa, raised a family
of four children, Albert, Fred, Ivan, and Sylvia. He instilled a
strong work ethic in his children, an attitude that every task must
be done to the utmost of one's ability, and the importance of
education as a lifetime process. His four children have received a
combined 11 college and graduate degrees from MIT, the Univer-
sity of Florida, Georgia Tech, American University, UCLA, and
Catholic University of America. Albert is a statistician living in
Bethesda, Maryland. Fred is an engineering manager in Cuper-
tino, California, married to Ellen, with two daughters, Alyssa
and Erin. Ivan holds a doctorate in computer science from UCLA
and is a Catholic priest in Austin, Texas. Sylvia is a busy mother
in Albany, New York, married to Tom Gray, with four children,
Tommy, Scott, Jennifer, and Kenny.
