A look at the process of moving
UBC research through the
commercialization process.
■ Moving a technology from inception
through to commercialization is an arduous
task with lots of hurdles along the way. But
for Ian Yellowley of the UBC Department
of Mechanical Engineering, years of hard
work is starting to pay off. He and his
colleagues spent more than six years
developing a patented process control
system architecture that meets the demands
of today's manufacturers for greater speed,
flexibility and control over the end product.
The system is now being marketed and
further developed through a West Vancouver company called Cimprovisor Hightech
Industries Inc. The company recently

is also acting as a consultant to Cimprovisor.

Science and Technology. We also
cover several interesting research
projects happening right here on
campus, from linking wireless networks
on the Internet to research into electric
power systems.
I would also like to call your attention
to the UBC Open House October 13-
15. The entire campus will be open to
the public from 10:00 am to 5:00 pm
each of those days, and in particular,
CICSR labs will have displays and
demos running, with faculty and
students available to discuss their
research projects. Please take advantage of this opportunity to meet us, and
learn more about our work.

To Market... continued from cover
installed its first system, adding its revolutionary control system to a high-speed
router for a company in the business of
fabricating kitchen and bathroom cabinets
and counter tops. Yellowley sees this as just
the beginning. "I see the company developing a whole range of machine tools based
on our architecture."
In the millworking business, the system
allows its users to more easily program
complex contours. The control system can
automatically slow the router down to get
around tight corners. The modular object-
oriented architecture is readily adaptable to
a huge range of problems and complexities
faced in today's manufacturing environment. "The controller can compensate for a
lot of shortcomings of the machine it is
controlling, and can make improvements in
performance and accuracy that are quite
dramatic," said Yellowley.
The emergence of global competition is
forcing manufacturers to automate more
processes as the market demands increase.
Manufacturers of the next century will have
to be able to deliver zero defects, flexible
part design, high quality at a low cost, and
they will have to be able to work with a
wide range of materials, and deliver in a
very timely manner. Only automation, and
flexible systems such as the one Yellowley
and his team have developed, will enable
manufacturers to meet these demands.
When Yellowley started the research six
years ago, he didn't set out to invent a new
type of architecture, but to combine process
control with geometric control on existing
modern control systems. This proved to be
so difficult and frustrating, the research
team instead developed a new way of doing
things. Yellowley and his colleagues feel
that the key to more effective control
revolves around the issues of adaptive
control and integration of extensive sensory
feedback . The result of this belief, the
Cimprovisor system, is a platform for
providing capabilities far beyond those
available with more traditional
architectures. Cimprovisor modularity
guarantees a predictable rapid response to
sensor input at each axis while maintaining
axis coordination.
There is little question that the system is an
improvement over existing, traditional
technology. But that doesn't make commercial success a given. Yellowley believes
that the development of a working prototype in the lab is just the start. Even the first
corporate sale by Cimprovisor is a small
victory compared to the full-scale commercialization he has in mind. He says it would
be easy to sell lots of systems if the
technology were licensed to a large
multinational manufacturer of control
systems, but he doesn't want to see that
happen. He is committed to seeing the
invention commercialized in B.C., so that
the jobs and the fruits of the knowledge he
and his team have gained stays here.
Selling next-generation control systems is a
tough job for a small company from B.C.,
but Cimprovisor has a lot of things going in
its favour. The company is well financed,
has experienced management, an excellent
product with large market potential, and the
continuing research support of Yellowley
and his team. 'It's not your typical cash-
starved, two-people-in-a-basement type of
start-up," said Yellowley.
However, time is of the essence for the
company. "The whole area of open control
systems is very competitive. We were one
of the first, but we need to get a lot of
systems out there to establish a solid
presence in the market."
However, Yellowley does not concern
himself much with the day-to-day operations of the company. He is busy heading an
aggressive research project aimed at making
improvements to the system, and adapting it
for other uses, notable for secondary wood
manufacturing. His research is funded by
Cimprovisor, NSERC and the B.C. Advanced Systems Institute.
Ultimately, his goal is to see the knowledge
he and other researchers in the province
have gained directly benefit B.C. In the case
of Cimprovisor, he'd like the company to
grow and succeed so that it can be a place
where students educated at UBC can go to
work, and feel both challenged and at home.
On a larger scale, he'd like to see B.C.-
developed technology used as a means for
residents of the province to control our
economic destiny by keeping the jobs, and
the wealth-generation potential of both our
wood products, and our advanced technology, right here in the place from which it
originated. ■ Linking Wireless Networks on 'the Net'
Victor Leung is part of a research team that is looking at ways to solve the complex problems that
arise in the process of linking wireless data networks to the Internet.
■ The use of internet is booming, both in
terms of a dramatically-increasing user
base, and a proliferation of services
available through the 'net'. Now, a group of
researchers, led by Victor Leung of the
UBC Department of Electrical Engineering,
is looking at ways to solve the problems
around linking wireless data networks to the
The project, which officially started this
summer, involves two universities and one
company. From UBC, Leung, plus two
Computer Science Department members,
Norm Hutchinson and Son Vuong, are
involved. Steve Hardy from the SFU School
of Engineering Science is involved, and
Motorola's Advanced Radiodata Research
Centre (ARRC) provides input, facilities
and funding. This three-year, collaborative
research project is also funded by NSERC.
According to Leung, the bulk of the work
will be done at UBC in both the Communications and Distributed Systems Labs.
Initially, the project team will focus on the
development and demonstration of an
internetworking environment consisting of
a test-bed interconnecting local area and
wide area wireless networks to the current
Internet, using the TCP/IP protocol suite.
As the Internet evolves to accommodate
multiple protocols, broadband multimedia
services and personal communications
services, the team plans to expand its
horizons to develop solutions to support the
Internet of the future.
Leung said there are two main issues that
the project will focus on initially. The first
is to work on ways for the networks to
locate users of wireless services once
they've travelled away from their home
base. Currently, users can sign up for
wireless service, and have TCP/IP connection, but they are given specific addresses
associated with the particular wireless
network they've signed on to. When they
move to a new location and onto a new
network area, it's difficult for messages to
find them.
"This is being remedied by augmenting the
IP protocol. Development is already
ongoing," said Leung. "We want to monitor
the development and see where we can
make improvements." The idea is to allow
users the freedom to move while retaining
their home base address. When they sign
onto a foreign network, the goal is to have
the system detect this and automatically
forward messages from home base to the
foreign network without the user doing
anything. There is a lot of complexity
involved in this process, especially when
the process involves users on the move
from network to network.
The second issue the project team is
tackling is a problem with the TCP
protocol when used with wireless networks.
The transport layer provides for end-to-end
data integrity, and has a built-in flow
control function that allows it to react to
congestion on the Internet. When the
transport layer loses a packet of data, it
assumes there is congestion, and will hold
back the transmission rate. However, for
wireless networks, which are inherently less
reliable than current wide area networks,
the TCP protocol's response is often not the
right one. It's not always congestion, but
could be signal fading, interference or other
problems that cause a packet to be lost.
Both wireless networks and TCP have built-
in error recovery systems, said Leung. "The
two do not interact in a predictable manner." With the bandwidth limitations of
wireless networks, it's important that they
operate at peak efficiency, which means
there is a real need for a solution to the
problem Leung and his team are tackling.
The impetus for the project came last
summer when Motorola invited Leung to
submit a proposal for their R&D funding
program. Motorola encourages research into
the development of applications of wireless
data networks, because without applications, they would not have a market for
their wireless data communications
products. "Motorola has products for
wireless data networking, but people don't
have a lot of applications for it yet. It's
beneficial for the company to encourage
applications in this area," said Leung.
His background is well-suited for this kind
of work. His research interests cover many
areas that combine telecommunications and
computer networking, including design,
evaluation and analysis of network
architectures, protocols, network management, control and internetworking strategies
for reliable, efficient and cost effective
communications. The thrust of his research
is to contribute to the development of the
emerging global network that will allow
ubiquitous multimedia communications
between people and machines, regardless of
where they are in the world, and even when
they're on the move. ■
Victor Leung of Electrical Engineering is collaborating with Son Vuong of Computer Science on linking wireless data networks. Facilitating Communications of the Future
Gerald Neufeld is developing tools that will enable the communications applications of the future,
such as video-on-demand and broadband multimedia communications.
■ Many of the communications technologies of the future that are developed in
Canada will owe a debt to the Canadian
Institute for Telecommunications Research
(CITR), a federal Network of Centres of
Excellence dedicated to advanced communications research. One CICSR member,
Gerald Neufeld of the Department of
Computer Science, is working on one of the
pieces that will allow applications to run on
the networks of the future.
Gerald Neufeld
"We're not interested in the
applications themselves,
but are developing the
infrastructure that makes
them possible. We're the
- Gerald Neufeld
CITR is divided into five main research
areas: design and management of
broadband networks, broadband services,
photonic devices and systems, mobile and
personal communications, and broadband
indoor wireless communications. Neufeld,
who is one of several CICSR members
involved in CITR, is responsible for a
project within the broadband services area.
He is developing a continuous-media file
server, which will make applications such
as video on demand and multimedia
communications possible.
"We're not interested in the applications
themselves, but are developing the infrastructure that makes them possible," said
Neufeld. "We're the plumbers."
In his continuous media file server project,
Neufeld chose an application that would
make the greatest demands on the underlying system. He chose news on demand
because it's the kind of application where
people request lots of short clips, and
interact quite actively with the system.
Video on demand is less taxing on the
system because people usually request a
movie and let it play for an hour or two with
few interruptions.
Neufeld noted that the development of
high-speed broadband networks is complex,
but that it is relatively easy to achieve high
bandwidth. How you deal with all that
capacity is the real problem. ATM (asynchronous transfer mode) switching was
developed to handle switching for these
new, powerful networks. But another
problem is how to enable computers hooked
into high-speed networks to handle the
volume of a network capable of throughput
of 622 Megabits per second (Mbps) or
more. Computers are designed to handle
just a fraction of that volume, so developing
techniques to enable the system to process
and organize huge volumes of data is a real
Neufeld is working with Mabo Ito of
Electrical Engineering on the problem.
They chose a multiprocessor host because a
single processor is not fast enough for what
they are demanding of the system. In the
development of a circuit board and host
interface, they chose to put the board
directly on the memory bus, rather than the
usual placement on the I/O bus to further
speed the processing. And they have
enabled processors to access the ATM card
in parallel rather than dedicating one
processor totally to one card. The result is
the kind of processing horsepower that can
be used as a continuous media file server.
The project will be complete in about a
year, but already the team has demonstrated
a working prototype. The broadband
services project within CITR involves four
related pieces of technology including
Neufeld's development of a continuous
media file server, quality of service
negotiation, scalable video encoding, and
application development. The pieces are
being put together at the University of
Waterloo, and the results to date were
demonstrated at the CITR national meeting
in Vancouver this summer.
Another related area that Neufeld is
working on concerns protocols that support
some form of real-time communication.
The basic problem is that given a variable,
continuous bit-rate stream, such as you
would find in the transmission of video,
how do you allocate system resources
across the switches in the most efficient
manner? Neufeld notes that if the network
is purely an ATM network, then ATM itself
will provide some of this allocation. But the
reality is that networks are not now, and are
not likely to develop into seamless,
homogeneous systems. The server on a
system may be ATM, but it could well be
connected to ethernet, token ring, or even
another form of ATM.
"The physical network is always changing,"
said Neufeld. "There are different forms of
ATM, and there may be other, completely
different ideas implemented in the future.
The TCP/IP protocol allows for the
continuum of many different networks on
the Internet, and Neufeld believes that the
mix of different networks is a reality that's
here to stay. He's planning to spend more
time on the problem of network management issues in high speed networking this
fall. In general his goal is to examine the
latest technologies in distributed operating
systems and computer networks and
protocols, compare their capabilities with
the applications the world wants implemented on these systems, and play a part in
bridging the gap and making it actually
work. ■ Chanson in Hong Kong
Sam Chanson has spent the past two years in the country he was born in, helping to found the
Computer Engineering Group at Hong Kong University of Science and Technology.
■ CICSR member Sam Chanson has been
noticeably scarce around the UBC campus
over the past two years. He has been
spending his time helping to found a world-
class Computer Science Department at the
Hong Kong University of Science and
Technology (HKUST).
The University was created in the late
1980s by the Hong Kong government with
the view that it was to become the premier
research institution in the Far East. An
important mission of the university is to
service the region's industry and commerce.
The University took in its first batch of
students in 1991.
According to Chanson, HKUST is different
from the other six universities in Hong
Kong in that it focuses only on science and
technology, and it follows the U.S. style of
operation instead of British. In fact, more
than 90% of its faculty members graduated
from universities in North America. Its
emphasis on research is reflected in the fact
that the ratio of graduate to undergraduate
students is about 25%, more than double
that of the other universities in Hong Kong.
Chanson landed his position at HKUST as a
result of a visit to Hong Kong in September
1990 to attend an IEEE conference. At the
conference he met Professor Vincent Shen,
the Department Head of Computer Science
at HKUST. He had known Shen at Purdue
University sixteen years ago when they
were both faculty members there. Shen told
Chanson of the vision of the university and
took him to see the construction site at
Clear Water Bay. "I became very interested
in the possibility of helping to start a
department from scratch to service the
region where I was born," said Chanson.
In January 1993, he joined HKUST. He was
given the task of recruiting faculty members
in Computer Engineering (CE), devising a
curriculum for the CE program, setting up a
CE Laboratory and formulating a research
focus and projects for the CE Group. In
addition, since he had experience looking
after the computing facilities for the UBC
Computer Science Department, he was put
in charge of overseeing the development of
computing facilities in the Computer
Science Department at HKUST, and was
asked to be the Associate Head of the
Department in July 1993.
Chanson said his job was made easy
because of the generous financial support
from the Hong Kong government and
Sam Chanson with research assistants Alexis
Berthillier (r) and Danny Chan.
industries. "We were able to set up computing facilities which would be considered
first rate by any standard." The CE group
now consists of 10 faculty members with
expertise in computer networks, distributed
and parallel systems, real time systems,
performance analysis, and theory of
distributed computing.
The lab has two 16-port ATM switches, 12
SPARC stations (mainly SPARC-20s with
multimedia kit), four high-end Pentiums,
FDDI, Ethernet and ATM networks, a laser
printer and access to a 140-node Intel
Paragon multiprocessor machine. The
Computer Engineering program started to
take in the first batch of students last year,
and the program attracted some of the best
students in Hong Kong, said Chanson.
Under his direction, the projects started in
the Department include: ATM congestion
control, multiparty video conferencing
system, video server research, parallel
algorithms and applications, parallel
programming environment and parallel
compilers, load balancing over heterogeneous networks and workstations, real time
kernel, protocol testing and verification, and
VLSI optimization.
Chanson is the principal researcher in
several of these areas. He has received more
than HK$10,000,000 (about Can. $1.7
Million) in research grants from the Hong
Kong government and some local companies for work on the CE projects. In the last
two and a half years that he has been in
Hong Kong, he has published 6 journals
and 21 conference papers. Some of the
"I applied much of
my UBC experience
to the HKUST
environment. The
most important factor
that makes a department great
is people - both faculty
and students. We are doing our
best to recruit the best people
and help them to attain
their full potential."

work was actually done at UBC, said
Chanson, who continues to visit the campus
on a regular basis to interact with his
students and colleagues.
He said he has learned a lot from his
experience building a program, a research
lab and a research group almost from
scratch. "Perhaps some of the important
things I have learned are management
skills, interaction with government and
industry, and the need for compromise."
He said the example set by the UBC
Department of Computer Science is an
excellent one. "I applied much of my UBC
experience to the HKUST environment. The
most important factor that makes a department great is people - both faculty and
students. We are doing our best to recruit
the best people and help them to attain their
full potential." ■ Enabling Computers to Make Decisions
Craig Boutilier is working on ways to enable computers to make useful decisions, even when there is
no perfect answer, and when they are many complex considerations.
(    5
Craig Boutilier is developing ways for computers to solve complex problems.
■ Computer systems have become fairly
adept at making decisions where the
information needed is factual, and the
decision required is black or white, with no
gray areas. But introduce uncertainties, multistage problems, or a decision in which
immediate consequences must be weighed
against long-term consequences, and the
smartest computer system is stymied.
Computer Science Department member
Craig Boutilier specializes in developing
ways to help computers solve just such
problems, but he recognizes the extreme
difficulty of this task. "Multi-stage or long-
term problems are computationally
intractable," said Boutilier. "My work
focuses on cases where I can come up with
useful solutions in reasonable time frames."
One way to approach this is to simplify the
problem to the point that a system endowed
with artificial intelligence, such as a robot,
can 'think' its way through all of the
ramifications of a decision and arrive at a
solution in a reasonable amount of time.
Boutilier uses the example of a robot that
can roam and has the job of personal
assistant. One of the first tasks of the day
for the robot is to get Boutilier some coffee
from the Barn (the coffee shop across the
street from the CICSR/CS building). A
number of factors affect the robot's
decision, including its location, the weather,
what other tasks must be done, their relative
importance to fetching coffee, and whether
or not Boutilier has coffee already.
"The robot has to determine what to do in
every possible situation, and the number of
possibilities grows exponentially with each
additional factor that must be considered in
the decision-making process," said
Boutilier. "To help simplify the decision,
we try to enable the program to identify, at
any given time, factors that are relevant,
and to ignore all irrelevant details. We also
try to have the robot approximate an
optimal solution, and not waste time trying
to come up with the very best possible
answer. If it has to deliberate for hours
before finally deciding it should get coffee,
and the morning passes before it makes a
decision, that's not a useful solution."
Boutilier is currendy looking at applying
his work on testing and repair processes in
manufacturing with researchers at Rockwell
International in Palo Alto. The problems
involved are complex. In the process of
putting together a device with thousands of
components, the resulting product doesn't
always work. Testing at each step of the
way costs money and is also fallible. In
coming up with an optimal testing strategy,
Boutilier has to balance the cost of testing
and repair with the cost associated with a
faulty product reaching the customer. In
doing so, considerations include the number
of times to test a faulty component, whether
or not to repair it, how many times the test
and repair cycle should be repeated before a
component is rejected, and numerous other
questions along these lines. The goal is to
consider the process as a whole, and devise
solutions that reduce overall costs.
"Algorithms can barely solve the one-
component case, let alone tackle problems
involving thousands of components," said
Boutilier. "Practically, an intelligent system
cannot give the optimal solution, but if it
can reduce overall costs, it has achieved its
goal. Approximation is the key."
Another research area that Boutilier is
working on is the development of languages
to allow people to customize decisionmaking programs. One application is a
software program that acts as an administrative assistant, updating the user's calendar,
picking up and sorting through e-mail, and
sending information requested by others.
There is no way to develop a standard
program that would meet every user's needs.
"You can't build the program once and for
all. It has to be interactive, and take into
account the user's preferences," said
Boutilier. One issue is that people don't
tend to talk in terms of probabilities and
percentages, or other concrete numerical
terms a computer can understand. So
Boutilier is interested in adapting a program
to the looser, more qualitative language of
everyday speech.
Generally, in the field of artificial intelligence, researchers are examining larger and
larger problems, but current computer
systems are only able to tackle small,
unrealistic problems. As the problems start
to approach the complexity of the real
world, researchers can't make the algorithms work in any practical way.
Now, AI researchers like Boutilier are
exploring the concept of 'bounded rationality' as a means to bridge the gap between
what is practical in the real world, and
possible with today's computer systems.
Boutilier provides this example to explain:
an intelligent robot is in the middle of the
road, trying to decide whether it's best to go
right or left. A truck is heading straight for
it. If the robot does not make up its mind
within seconds, its decision will become
irrelevant. Any move is better than no move
at all. Says Boutilier, "Good solutions are
only good if they're timely. Ultimately
that's the way things are going to go." ■ A Position of Power
Hermann Dommel is awarded a chair in electric power systems.
■ CICSR member Hermann Dommel was
recently awarded a new chair to support
electric power systems engineering research
at UBC. The chair is for five years'
duration, and is funded by NSERC, B.C.
Hydro and their research subsidiary,
Powertech Labs.
According to Dommel, B.C. Hydro made
the move to establish the chair to strengthen
electric power engineering education and
research at UBC.
Power system analysis using computers has
been the focus of Dommel's research for
many years. "The electric power industry
has been a heavy user of computers from
the beginning," said Dommel. That's
because power transmission systems are
interconnected into very large, complex
systems that have to work together. For
example, the power system in B.C. is linked
along the west coast of North America all
the way to Mexico. If there's a short circuit
in a substation in California, we feel the
effect in B.C.
The sheer size of the system puts strain on
it. Dommel uses the analogy of a drive shaft
in a mechanical engine — if the rods are too
long, they are put under increasing strain,
and eventually, they twist or break. He says
that today's power systems have similar
stability issues, and that the strain on the
system is increasing.
One of the reasons is that the nature of
power systems is changing with the advent
of independent power producers, whereby
anyone can be a power supplier by building
a plant and putting their power onto the
transmission grid. While this is a way to tap
many potential new sources of power, it
also complicates the grid and causes a lot of
technical problems for maintaining
frequency, stability and power quality,
according to Dommel.
Dommel's research focuses on a specific
problem that can occur in complex power
systems: fast electromagnetic transient
phenomena. In any transmission line, there
are breakers at both ends. When connecting
the line, one of the breakers closes first and
sets a wave in motion that can lead to
overvoltages. When a transformer fails, it is
often due to such overvoltages.
He and Jose Marti, also a member of the
UBC Department of Electrical Engineering,
have developed a computer program to
Hermann Dommel (seated) surrounded by his
research team and students of electric power
analyze the causes of transients and to help
prevent it from happening. The program is
currently being used at B.C. Hydro, and
many power corporations across Canada
and around the world. There are actually
three different software packages currently
on the market that were designed for this
purpose, and Dommel and Marti have had
their hand in all three at different times.
The version Dommel has most recently
worked on is sold through Microtran, a
UBC spin-off company. There is also a
larger version developed commercially with
industry collaboration, and another program
developed by the Bonneville Power
Administration (BPA). Dommel worked at
BPA for eight years before coming to UBC
in 1973, and worked on the software while
he was there.
In connection with his new research chair,
Dommel plans to do a lot more work on
stability in large power systems. Stability is
a pressing problem because utilities are not
permitted to build transmission lines or new
power plants as readily as they were able to
in the past. "The system is being operated
closer to the limits of what it can handle
compared to the past," said Dommel.
He and his research group are studying new
control techniques that will depend heavily
on computer controls to run power systems
as efficiently as possible.
As the power grid moves closer and closer
to its operating limitations, the danger of
problems such as blackouts increases. In
B.C., we have become accustomed to a very
reliable power system. Dommel and his
research team are working on ways to
ensure things stay that way. ■
