THE SEARCH FOR NEW MATERIALS

With laboratories running at full speed, scientists and engineers

at HKUST are making important strides in their quest to under-stand and develop new materials for the industries of the 21st century.

Lighter, stronger, more efficient plastics, ceramics, and composites. Biomaterials for medical devices able to interact with biological syst~ms. "Smart fluids" that can be reversibly transformed from a liquid to a solid phase, instantaneously taking on programmed shapes in a manner that could render some mechanical gears and valves obsolete.

Advanced materials like these are the product of knowledge and invention. At present, the pursuit of knowledge is leading researchers ever deeper into the microstructure of materials,

where they seek to understand events at the molecular and atomic

The atom is the fundamental building block of crystalline materials. Crystal growth taking place on an atomic scale is illustrated in this image of a silicon crystal sill/ace take/! by Dr Micltael ALTMAN (Physics), nsing a low energy electron microscope. The dark lines distinguish layers of growth, or atomic steps, !ltat differ frolll each other by only 10·/0 meters, the height of one atom. As a semiconductor, silicon is the most widely used material in IIlicroelectronic devices today.

A new type of molecule can be see/l in the volcano-like stl'llctures formed by rings of six carbon 82 fullerenes, each touched with a neodynium atom, on a lattice made of smaller carbon 60 fullere/!es. This image, taken with a sCn/lIling tmllleling microscope, shows a stl'llcture approximately 1.2 ltanometers high with a diameter of 4 nanometers. Graduate student Nian Lu~ and Prof Nelson CUE (Physics) are studying the electronic properties of the altered carbon 82 molecule and its intel/ace with the lattice below.

levels so as to control the properties determined there.

In this microscopic world, where dimensions are measured in billionths of a meter, HKUST researchers are especially intent on investigating the electrical, optical, and magnetic properties of novel materials that may form the basis of the information technologies of the future.

Some very striking images of these materials have been obtained using the powerful instruments in the University'S materials science laboratories. A few of them are presented here-as much for their strange beauty as for the glimpses they provide into the all-important search for new materials.

Clusters are groups of atoms from two to several thousand in number that constitute a new class of materials. This image, taken with a transmission electron microscope, shows clusters of a carbon 60 derivative, a fullerene lltaterial prepared by Dr BellzllOllg TANG (CllCmistry). Fullerelle materials are so-called because their moleClllar stl'llcture resembles the geodesic domes desiglled by Buckminster Fuller. Til additioll to

PRESIDENT'S PROGRESS REPORT

HKUST's International Endeavors

In

my remarks at the University's Third Congregation, I said that we had come a long way towards achiev-ing the goal of buildachiev-ing a world-class technological institution, and that we should now set our sights on human-izing the institution by making it more

genteel, more cultural, more Chinese, and more international.

In this report, let me describe two of our recent initiatives on the international front.

Hong Kong sits at the crossroads of East Asia, North America, and Western Europe. As a result, HKUST finds it natural to develop and maintain robust working relationships with like institutions in these regions.

Faculty members at HKUST have always collaborated with

overseas colleagues individually. Many of our Schools and Departments maintain cooperative agreements with overseas counterparts. However, at the University level we have signed

very few agreements, since documents of that type frequently contain little actual substance. Our preference is to support

endeavors initiated at the working level, and to find ways to provide infrastructures that can lighten the faculty's administra-tive burdens and bring them additional resources.

Members of our faculty hail from over 30 countries, but an overwhelming majority earned their doctorates in North America,

especially the United States. It is therefore to no one's surprise

that our academic links to North America have been strong. The infrastructure required here is one that sLlpports HKUST's

eco-nomic development mission. We vigoroLlsly promote applied R&D and technology-oriented partnerships with North

Ameri-ca's business and industrial sectors.

Association of East Asian Research Universities

Strange as it may seem, interactions among the academic sectors of East Asia have not been all that significant. If,

how-ever, a small number of universities oflike vision and compara-ble quality were to come together to form a regional association, such a body could serve to facilitate the work of faculty and students who wish to engage in cooperative ventures.

Recently, the presidents of nine East Asian universities decided to meet on the HKUST campus to explore the possibility of forming such an association. They represented:

Chinese Mainland - Fudan, Tsinghua (Beijing), University of

Science and Technology of China [USTC]

Japan - Tokyo, Tsukuba

Korea - Pohang University of Science and Technology [Postech],

Korean Advanced Institute of Science and Technology [KAIST]

TailVan - Tsing Hua (Hsinchu) Hong Kong - HKUST

SPRING 1996

These institutions (plus several others which have since

indicated their interest in joining as founding members) all have

significant strengths in science and technology. They also share

many other common traits, including academic profiles, educa-tional goals, faculty composition, research capabilities, and traditional East Asian values.

During the meeting, the original idea of simply forming an association of technological universities expanded. The out-come was the establishment of the Association of East Asian Research Universities with an initial focus on science and tech-nology.

A Board was also established to serve as its governing body. I was elected Chairperson, and President Hiroyuki YOSHIKAWA of the University of Tokyo was elected Vice Chairperson, to

sei·ve along with Presidents Sooyoung CHANG (Postech), Chun-Shan SHEN (Tsing Hua), and YANG Fujia (Fudan) as Board Members for a term of two years. The next general meeting will be held in Tokyo and Tsukuba. It is expected that joint academic activities will commence at that time.

Areas of early action will revolve around the exchange of faculty and students; development of common curricula and transferable credits; sharing offacilities, information, and

mate-rials;

coopera-tion on aca-demic and

ap-plied research projects; and joint sponsor-ship of topical conferences, student con-tests, and in-ternational

events.

Europe I1lstitute at HKUST

Although European interest and presence, other than Brit-ish, have not been strong in East Asia, this situation is expected to change rapidly as China and other East Asian countries continue to surge ahead economically. Hong Kong is perfectly located to contribute to, and benefit from, the change.

Over the past year, we have worked towards the

establish-ment of a technology and manageestablish-ment-based Europe Institute on the campus of HKUST. The Institute is to serve as an umbrella covering a number of national Centers. For HKUST' s

faculty and students, each national Center will facilitate person-nel exchange and research collaboration with institutions in that nation. At the same time, it will provide footholds and observa-tion platforms for that naobserva-tion's universities, R&D organizaobserva-tions,

foundations, and multinational corporations which now show

keen interest in East Asia but are not yet ready to risk major investments.

This concept was discussed with, and among, the

Consuls-General in Hong Kong representing nations of the European Union, some of whom have visited our campus frequently. The

HKUST IN ACTION

Consuls-General from nations making up the European Union visited the University on 12 February to work with us on establishing a Europe Institute at HKUST. The technology and management-based Institute would house a number of national Centers .

• Nine senior officials from the Hong Kong Govern-ment spent the month of February studying Cantonese at HKUST in an innovative course devised by the University's Language Centre for the Civil Service Training Centre. The expatriate officials concentrated on gaining fluency in the kind of Cantonese needed to conduct government business, including oral presentations and fielding questions from the floor.

establishment of a Europe Institute received enthusiatic support from all. In February they came as a group to meet with our academic administrators and some of our senior faculty, and to discuss the agenda in detail. A Steering Committee consisting of EU and HKUST representatives is being formed.

Preparations for setting up a German Center ha ve progressed rapidl y. U ni versity presidents, leaders of Fraunhofer Institutes, and the president of the German Research Foun-dation have visited HKUST and are help-ing to lay the ground work.

Preparations for setting up a Brit-ish Center commenced following my March trip to London, Manchester,

and Warwick with Vice-President for Administration & Business Paul BOL-TON, under the sponsorship of the Brit-ish Trade Commission British Council, and UK's Foreign & Commonwealth Of-fice.

• A milestone in the University's campus development was celebrated on 28 March with the Topping Out Ceremony for the new Graduate Residences, University Center, and Senior Staff Quarters. Mr Martin HADAWAY, Group Managing Director of Gammon Construction Limited, and President Chi a- Wei Woo presided over the ceremony.

Summit, to be held in Hong Kong in the autumn of 1996 and 1997.

A New World Order

The Asia-Europe summit meeting held in Bang-kok in March heralds the development of what I

have called a New World Order, in which a third key link-between East Asia and Western Europe-will join the

time-honored North American-Western Eu-ropean alliance, and the North Ameri-can-East Asian economic partnership, to complete a triangular balance of in-ternational power. Compared with the current situation which finds the United States alone at the pivot directing East-West traffic, this New World Order will be a much more stable structure for peace-ful coexistence and co-operation.

It is my hope that the Europe Institute will contribute to the operation of the World

Economic Forum's Europe-East Asia Economic A New World Order

We at HKUST foresaw that develop-ment, and will contribute within our capability to the structuring of this New World Order. D

BUILDING A UNIVERSITY

Depa

r

tment of Economics

A s part of the School of Business and Management at HKUST, the Department of Economics encourages a comprehen -sive understanding of the scope of e co-nomics as a discipline. Rather than nar-rowing its focus to the strictly quantitative

or theoretical aspects of economics, the

Department has created a strong teaching and research environment in which ec o-nomic theory is developed and applied to broad areas of practical concern.

"We have a strong interest in busi

-ness economics," says Department Head Leonard Kwok-Hon CHENG, "and that is good because it ties us to the real world. Economics should be about business as

well as public policy or social science. I

like the fact that we are in the business

school."

Other important application areas are economic growth and development and international economics. "These choices

obviously reflect our location in the mid-dle of the Asia-Pacific dynamic growth area, as well as Hong Kong's status as an international trading and financial center," says Prof Cheng. "Our aim as a Depart

-ment is to be global in the standards we

maintain and the audience we reach, but with an emphasis on local and regional issues."

At the core of the Department is a concentration of expertise in economic

theory and methodology. "It's important that we provide solid training in economic analysis," Prof Cheng explains. "Not only is it the foundation of our own discipline,

but it also provides a methodological

ba-sis for some other disciplines in the bus i-ness school. Economic analysis is an es

-sential ingredient of business research."

Economic analysis can be qualitative,

quantitative, and statistical in nature. The

name given by economists to the pro

ce-dures they've developed by combining economic theory and statistical analysis is econometrics. As Prof Lung-Fei LEE, a distinguished econometrician and Fellow

of the Econometric Society, explains,

SPRING 1996 "Econometrics is a calculation tool to explain or forecas t economic ac -ti vities." A re -cent project il-lustrates how it can be used to quantify various items of interest. Mostpeo

-Prof Lllllg-Fei LEE, a distill -gllished ecollollletriciall, is olle of three Chillese lIIellluers

elected to the Ecollollletric Society.

pIe believe that university graduates earn more than those who start to work right after finishing their secondary school edu -cation. But if a survey finds that university oraduates earn 10% more, Prof Lee ar -b

oues "we still do not know how much of b ,

this 10% is due solely to university study."

A person's earning capacity could also be affected by factors such as talent, family background, and interest in the subject

studied. Using simultaneous equations,

Prof Lee has constructed a model that can

estimate these relations and be used to

explain income differences.

What distinguishes economics from fortune telling, then, is the ability to create economic models that can account for the

data and be empirically tested. In recent

decades, as economic forecasting has b

e-come more sophisticated owing to ad

-vances in econometrics, the study of

eco-nomics has increasingly become an opera

-tional discipline geared to providing pra

c-tical advice. "Models such as these are

important for decision makers as they pro

-vide a frame of reference for the allocation of limited resources," says Prof Lee.

Econometrics is what economists do,

not what they study. Within economics as

a discipline, the terms microeconomics and macroeconomics are used as broad categories designating the level or scale of analysis. Microeconomics deals with the economic activities of individual cons

um-ers, business firms, markets, and so on.

Macroeconomics is concerned with the economy as a whole, focusing on the ag-gregate outcome of individual actions.

Monetary systems, investment flows, busi

-ness cycles, and levels of employment,

taxation, and inflation are typical subjects

of macroeconomic theory.

Busin

e

ss Economics

At HKUST, the principal area of microeconomic study is business econom

-ics. "Basically, what we do is use eco

-nomic principles to analyze the behavior

of firms and solve problems of organi

za-tion and strategy. In this way, we can help

corporate managers compete successfully

in various market environments," says Dr

Changqi Wu.

Undergraduate economics majors are

asked to choose one of two special izations offered in the program: Business E co-nomics, leading to a BBA degree, or Eco

-nomic Science, leading to a BSc degree. In the former, students focus on problems

related to a company's internal operation

and economic environment, and on

eco-nomic reasoning as an essential element in sound business decision making. In the

latter, the focus is on the scientific basis of economics and on economic problems and solutions viewed from the perspecti ve of

policy makers and social scientists.

In business economics, renewed at -tention has been placed in recent years on developing adequate theories of business organization. One topic of particular re

l-evance for this region is the structure of shared ownership agreements, including

joint ventures. Dr Zhigang TAO and Dr Wu are currently collaborating on a study of joint ventures in China that examines

the balance of incentives and control for the Chinese and foreign partners. "By analyzing different joint venture options," says Dr Tao, "we can determine the prin -ciples for optimal structuring of such

or-ganizations. This should be of benefit to the business community, as well as a con

-tribution to the theory of the firm."

One type of agreement is a "contrac -tual joint venture" giving the foreign in

-vestor a progressively declining share of

ownership. In non-high-tech industries,

Dr Tao sees this as a workable solution for foreign companies that depend on tech

-nology transfer to do business in commer

-cial environments lacking strong protec

-tion of intellectual property rights.

Another area of interest for business economists is industrial organization

-the distribution of firms within an indu

s-try, their competitive behavior, and gov -ernment regulation. "Some companies in

(5)

Hong Kong claim that they are not mo-nopolizing their industry," says Dr Siu Fai

LEUNG. "Otherwise they would have to

face the government's stringent cQntrol.

Microeconomic theories give us a context in which to test their claims."

Economic Growth (Ind Development

The Asia-Pacific region is arguably

the world's most compelling laboratory

for the study of transitional economies. Within this region are strikingly varied

examples of how government policies are used to guide economic reform and attract

foreign trade, investment, and technology

transfer. And yet, as in other developing

regions, the difficulty of mounting a sci-entific study of these processes cannot be

underestimated. For economists, as for

other social scientists, the difficulty has to

do with the availability, or lack of it, of

reliable data in much of Asia and South-east Asia.

"In China, where much of our

atten-tion is concentrated, the situation has

im-proved," says Prof Cheng. Currently, data

acquisition by foreign scholars is a largely commercial proposition, unlike 10 or 15

years ago when data sets were unavailable

except to those enjoying a close personal

relationship with the proprietors of the

data. It is expected, too, that the situation will continue to improve with the further development of academic and professional infrastructure in China.

At HKUST, the half dozen econo-mists studying China's economic devel-opment are led by Prof Justin Yifu LIN, an

internationally recognized economist who divides his time between Hong Kong and

Beijing, where he is Director of the China Center for Economic Research at Peking

University. With his leadership, HKUST

scholars look forward to accessing impor-tant data sets that have not been available for study so far.

With such data, HKUST economjsts

plan to collaborate on comprehensive

re-search studies that may take several years to complete. To facilitate such projects,

and to coordinate the interdisciplinary work of scholars from other departments,

the University'S Centre for Economic De-velopment was established in August 1995.

According to its Director, Dr Francis

T. LUI, the Centre for Economic

Develop-ment promotes research on China's eco-nomic reforms, the economic integration of Hong Kong and the Pearl River Delta,

and the emergence of regional economies

in China, particularly the region

compris-ing the southern coastal provinces. It also recognizes the importance or international comparisons and research on economic

development theories.

For its inaugural event, the Centre

organized a substantial Conference on South China's Economic Development,

held at HKUST on 15-17 August 1995.

The conference attracted a large group of

economists from China, as well as their

counterparts in Hong Kong.

In June of this year, the Centre will

host an international conference on Capi-tal Flows in Asian Countries, co-spon-sored by the US National Bureau of

Eco-nomic Research. One of the principal top-ics at the conference will be capital flows and ex-change rates in Hong Kong and Asian countries. "Cooking Fish"

In a commercial and financial center like Hong Kong, an important meas-ure of credibility is earned

by academic economists who find ways to use their expertise in the service of the community. In keep-ing with the mission of the University, members

of the Economics Department have been assiduous in creating opportunities to

in-teract wi th colleagues in business and gov-ernment.

"We see this as vital," says Prof Cheng.

"We are making an effort to build bridges to the business community and to position ourselves so that we can have an impact on policy making and public discussion of important economic issues."

In addition to offering executive de-velopment courses, Department members have provided consulting services to busi-ness organizations, government agencies,

and conmlercial and professional associa-tions. For the past three years, a half dozen Department members have also contrib-uted a regular column called "Cooking Fish" to the Hong Kong Economic Jour-nal. Taking its name from a passage in

Lao-tzu which counsels a ruler to govern a nation in the same way that you cook a

small fish, the column offers commentary on economic issues of the day, including

social security, unemployment, public housing, MFN, and Hong Kong's drive to develop high-tech industries. In 1994,

col-umns on the Government's proposed old-age pension scheme attracted much atten-tion and the ensuing public discussion led to reconsideration of the plan.

The result of all these efforts is mani-fest in growing recognition of University

economists as an important intellectual resource in the community. The Hong Kong Government recently asked the De-partment to undertake research on issues related to APEC, and the Financial Secre-tary has appointed Prof Cheng to the

Gov-ernment's Economic Advisory Commit-tee.

With a new master's degree program in economics launched this year, the De-partment anticipates increasing its faculty roster from 25 to 28 as the University reaches its planned capacity in the next two years. "We have a lot of work to do in developing our teaching materials and skills and our expertise on local issues,"

says Prof Cheng. Nevertheless, the De-partment of Economics is looking forward with confidence to expanding its research programs on the local and regional

econo-mies and to continuing its multifaceted

service to the community. D

RESEARCH

DEVELOPMENT

BUMPER HARVEST FOR TECHNOLOGY TRANSFER

The academic year 1995-96 is proving a particularly good one for the Technology Transfer Centre and its private-sector

coun-terpart, the HKUST RandD Corporation. Between 1 July and 31 December, 21 third-party contracts were signed by the RandD

Corporation, worth a total of $5.1 million. This represents an

increase of more than 60% over the $3 million in contracts earned during the whole of 1994-95, and a total increase of two

to three times is expected by the end of June.

This increase is a result of several factors: the maturing of a young institution finding its strengths and making a place for

itself in the community, the University's success in appointing faculty members who already have an international reputation

for excellence, and the strengthening of TTC.

The contracts, ranging from cooperative research

agree-ments to projects worth around $1 million, tap University exper

-tise in diverse fields such as biotechnology, manufacturing, and Cantonese teaching. We will highlight just three of these projects

here.

Dr Zaheed KARIM'S work with chip-on-glass technology (see next page for details) represents the University's fourth

contract with Motorola, all with different divisions and involv-ing different faculty members. This evolving relationship with Motorola is an important confirmation of the growing recogni-tion of the University as a valuable R&D partner in the eyes of Hong Kong's industrial sector.

Two new contracts signed with Apotech International Ltd are the third and fourth licensing agreements obtained for Prof 1. Tze-Fei WONG'S controlled-release drug delivery technology.

"The biopharmaceutical industry in Hong Kong is really just starting up, so very few companies are large enough to devote enough resources to the development of new drugs," Prof Wong explains. "The advantage of concentrating on drug delivery for

local industry is that it's high technology but not as expensive as the development of new compounds."

The licenses to Apotech cover the manufacture of sus-tained-release oral preparations of four non-proprietary drugs.

The main advantage of sustained-release preparations is that blood concentrations of the drug are kept fairly constant and

within the therapeutic window, eliminating the si

de-effects often caused by rapid-release drugs. Also, the patient may only need to take tablets once instead of

three or four times per day.

Although controlled-release technology is not new, most currently available preparations are either under patent or closely Stl"llctllre of the • slIstailled-release oral preparatioll. SPRING 1996

guarded secrets. Because of this, Prof Wong and his coworkers

have been adept at exploiting the opportunity to provide new

technology to local and regional manufacturers.

Their system of drug delivery, developed in conjunction with the Guangzhou Pharmaceutical Industrial Research Insti-tute, uses sugar-starch spheres impregnated with the drug and coated with a specially developed polymer rate-release

mem-brane. When the drug-bearing spheres arrive in the stomach,

digestive enzymes and juices work to break down the rate-release membrane. Gradually, the drug is released and absorbed

into the blood stream as the spheres move down the digestive tract and through the intestine.

Once these new preparations are commercially available, this therapeutic technology will be accessible to the many pa-tients in Asia who cannot afford the current preparations.

Hong Kong has long had a reputation for plastics-and recently, for precision plastic components for high-tech indus-tries. As the Hong Kong economy matures, local industry is becoming a provider as well as consumer of manufacturing

technology. Hong Kong is now one of the world's largest sup-pliers of injection molding machines, due to low unit price.

Hong Kong industrialists, however, want to compete on

quality and technology as well as on price. To make this possi-ble, HKUST's Chemical Engineering Department is

collaborat-ing with a world leader in control technology, Moog

Interna-tional, to modify an adaptive control technology developed by Dr Furong GAO for use in controlling injection velocity and

packing pressure in injection molding machines.

Although injection molding seems a simple process, many parameters, such as the material properties of the plastic, the

temperature, and the geometry of the mold, interact during the process dynamics. Current controllers-devices used to control the input and output of a machine-use fixed control parameters

to calculate the controller output based on injection velocity or packing pressure. As a result, there is a down-time for trial-and-error retuning whenever there are changes in the materials,

mold, or other process conditions.

The aim of the project undertaken with Moog is to develop a prototype controller able to adapt to altered conditions within pre-set molding param-eters, resulting in more efficient quality

CENTRE FOR DISPLAY RESEARCH OPENS FOR BUSINESS

The Centre for Display Research (CDR), one of HKUST's premier R&D facilities, officially opened on 17 January 1996.

But work on the Centre has been in progress since August 1994, when Prof Hoi Sing KwoK of the Department of Electronic and Electrical Engineering and research collaborators from other departments at HKUST received an unprecedented $14.4 mil-lion grant from Hong Kong's Industry and Technology Develop-ment Council.

The Centre for Display Research is devoted to research and development work on liquid

crys-tal displays (LCDs). First patented in the late 1960s, these devices are normally composed of a very thin layer of liquid crystals sandwiched between two high-quality, thin glass plates. An applied electrical field causes the liquid crystals at a given spot to change their essential quality from being clear to being opaque. The controlled response of liquid crystals to electricity is the fundamental principle driving LCD technology.

Creating complex images re-quires a transparent matrix or grid

This new technology is called "flip-chip" bonding. A silicon chip, which regulates the amount and rate of electricity supplied to each track in a matrix, is placed upside down directly on the bottom glass plate of an LCD. The gold bumps on the chip can be spaced 0.07 mm apart as opposed to the contacts on conventional plastic film which re

-quire a separation of 0.3 mm. Rllbbil/g 1IInchille il/ the Cel/tre's stnte-of-the-nrt fncilities.

At present, Hong Kong pro-duces approximately 20% of the world's LCDs, but most if not all of the LCDs produced in the territory are low-end displays.

These include basic, non-matrix LCDs used for digital watches as well as passive matrix LCDs used for pagers and electronic dictionaries.

of horizontal and vertical tracks to be etched on the glass plates. The matrix on a typical pager display consists of 16 horizontal and 120 vertical indium tin oxide (ITO) electrode tracks. By rapidly applying voltage to selected tracks in succession, a programmed image or message can be formed.

The beauty of LCDs is that they are flat and thin. Unlike bulky cathode ray tubes, LCDs have opened up a burgeoning market for personal electronics, ;naking it possible to create a wide range of new applications, including pagers, laptop com-puters, and hand-held color televisions.

One of the Centre's primary goals is to advance thin-film transistor (TFT) technology for use in active matrix LCDs. By placing a tiny transistor and capacitor at each junction in a display matrix, the charge needed to turn a pixel on or off can be stored, thereby eliminati ng the need for the constant reapplication of voltage required to maintain a static image; tlus in turn makes possible larger-sized displays. Progress in this area has already been made at CDR with the development of new improved TFT structures and chemico-mechanical polishing processes.

While much of the work at the Centre concentrates on active matrix LCDs, researchers have also discovered ways to improve the quality of passive matrix LCDs, thereby extending their potential use in products. In a contract signed with Motorola Semiconductors H.K. Ltd, Dr Zaheed KARIM of the Department of Electrical & Electronic Engineering has successfully demon-stt'ated the feasibility of mounting chips directly on glass LC panels using gold bumps and specially designed polymers to provide connections with the ITO tracks in a passive LCD matrix.

According to Prof Kwok, if Hong Kong is to survive in this very competitive market, it is going to have to upgrade its technology and manufacturing base. Production of low-end LCDs will, to a greater and greater extent, be dominated by developing countries where labor costs are low. The present-day cost of producing non-matrix LCDs is roughly $2 per square inch, whereas that of producing large active matrix LCDs is approximately $80 per square inch- 40 times as much. This cost differential provides Hong Kong with an incentive to establish a foothold in the lucrative active matrix LCD market.

Despite the fact that Japan and Korea have created an oversupply of lO-inch-diagonal color LCD screens for notebook computers, Prof Kwok feels confident that Hong Kong can compete successfully in the niche market for 4-inch-diagonal

LCDs, such as those found on camcorders and projectors.

Entering this market would normally require an investment of over $200 nullion for capital equipment and a similar amount for human resources-much more than most companies can afford. By making its research expertise and state-of-the-art equipment available to local industry, the Centre for Display Research promises to provide Hong Kong with a fast path to developing the technology and skills needed to access the grow-ing worldwide market for matrix LCDs and to secure its future

in LCD production. 0

STUDENT COMPUTER PROGRAMMERS ARE

"BEST OF THE BEST OF THE BEST"

Improving on their excellent

performance of last year, the

HKUST computer

program-ming team placed 11th at the

ACM international finals held

in the United States in

Febru-ary, putting them in the top 1%

of the world's student compu-ter programmers.

The four-member team,

made up of computer science

students Ken WONG Wing Kin,

Chesney WONG, Vincent Ip

Ting Pong and alternate NGAN

Sai Fong, solved five out of a

possible seven problems in the four-hour time limit at the ACM

International Collegiate Programming Finals held in

Philadel-phia on 17 February.

This year's contest was the largest ever, with 1,001 teams

around the world competing in local contests and 43 making it

through the regional semifinals to the finals. At the ACM finals

last year, the HKUST team (both Ken and Sai Fong were

members) placed 13th out of 38 finalists from a starting field of

789 teams.

''Their performance shows a high level of consistency," says their coach, Dr Michael STIBER, an assistant professor in the

Computer Science Department. "They have proven that their

excellent showing last year was no fluke. They are the best of the

best of the best, and they have the potential to do even better."

In fact, Dr Stiber says the team came "heartbreakingly

close" to solving six of the seven problems, a feat which would

have placed them among the top five teams in the world.

"They were seconds away from finding a typo in the

This year they beat formidable competitors such as Cal tech,

Carnegie Mellon, Columbia, and Toronto and placed well ahead

SHARP IDEA EARNS STUDENT $10,000

If

you want great ideas for

elec-tronic gadgets that will appeal to

young people, whom would you ask? Why young people of course,

and ones with expertise in

elec-tronics preferably.

This is exactly what Japanese

electronics giant Sharp decided to

do, and one young student from

HKUST walked away with a

$10,000 scholarsh i p and a fi ve

-day trip to Japan for his bright

idea.

Second-year student LEE Wai Ki's prize-winning idea' was

of their Asian rivals. The next best showing by a

regional competitor was by the team from the

Korea Advanced Institute of Science and

Technol-ogy, which placed 34th, followed by Tsing Hua

(38th) and Taiwan (40th).

"This contest tests fundamental computer

sci-ence background--the ability to look at a real

problem and find the underlying algorithm to get

it to work and the

talent to write a

workable

pro-gram quickly," Dr Stiber says.

"Our showing at

these con tes ts

demonstrates

that our

curricu-lum is on par

with the best; it is world-class."

The team members themselves give high marks to their

coach, who spent the months before the finals prepping the

students in weekly four-hour practice sessions or "simulated contests" .

Dr Stiber is now in the process of rebuilding the team forthis

year's round of contests. At a recent meeting open to all students

interested in computer programming, 35 new recruits tried their

hand at solving a few practice problems from the Internet

ar-chive of past ACM contests.

However, "with a three-year degree program, we are at a

disadvantage," says Dr Stiber. "Students are generally best

prepared to compete in their third year. Teams from a four-year

university have two years to compete at that level."

The Association for Computing Machinery, sponsor of the

annual competition, is the leading international professional society in computer science. 0

home.

Although Wai Ki does not know

if Sharp will eventually manufacture

his design, he thinks he can come up

with other innovative ideas and make

a career for himself in electronics. "I want to be an overall engineer--to take a new product through all the production stages from beginning to end. But the idea is the most difficult part." 0
