A look at the trend towards
increased funding for research
with an industrial focus.
■ For those university researchers interested in collaborating with industry — and
most CICSR members are — there has been
a noticeable increase in funding sources
over the past few years. That's in part due
to the creation of new programs that require
industry collaboration, and in part due to an
increased emphasis on industrial collaboration from some of the traditional funding

■ This issue of our CICSR Newsletter
focuses on the increasing importance
of industrial relevance and participation in research for Information
Technology. This trend has been
apparent over the past several years,
and is now firmly established in
federally funded programs (like
NSERC and the NCEs) and provin-
cially-funded programs (like ASI and
the Science Council of B.C.). Several
examples of successful industry-related
programs involving CICSR members
are given here, along with interviews
with representatives of granting
In addition to the encouragement of
industrially-relevant research by the
granting agencies, more and more
faculty members are finding interesting research problems in industry —
not only in Engineering, but also in
Computer Science. At the same time,
industry is discovering that academic
researchers can and will help solve
their problems.
This trend is bound to continue, and
hopefully will result in the production
of more and better products and
processes, and in making Canada more
competitive in the global marketplace.!
Dr. James Varah, CICSR Director
FUNDING ... continued from cover
feels the trend is a good thing for the
Canadian economy. "Canadian science and
engineering research is recognized worldwide, but in the commercialization of our
research, we could do far better," said
Salcudean. "There is a general desire that
universities play a larger role in the
economy of the country. It is felt that
university-based research can contribute to
the competitiveness of our industries."
At UBC, university-industry collaboration
has increased dramatically in recent years.
According to Salcudean, the industrial
component of research funding has
increased several-fold. "There are many
new programs addressing the needs of
industry. Researchers should be aware that
there are opportunities out there for them, if
they have an interest in working with
In her own research, Salcudean has a strong
industrial component. She has been
working with industry for many years. For
example, she did some work on the safety
of nuclear reactors. The results of her
research have been incorporated into the
Atomic Energy of Canada Ltd. safety
Salcudean is also working with Ian
Gartshore of the Department of Mechanical
Engineering on investigation into film
cooling of turbine blades to protect them
from the hot gas in the environment they're
used in. She and Gartshore have been
working on this problem for more than five
years, and have received funding from both
Pratt and Whitney Co. (Canada) and the
NSERC collaborative research funding
program. P&W are now incorporating
Salcudean and Gartshore's work in their
new engine design.
Salcudean and Gartshore are also involved
in an international research project on black
liquor recovery boilers used in the process
of making pulp and paper. The boilers cost
about $100 million each, and every pulp
and paper mill has one, so there is a strong
interest in the work, which is aimed at
increasing productivity, reducing pollution
and making more efficient use of energy.
The project, as well as Salcudean's other
industrial projects, receives a combined total
of more than $500,000 in funding annually
from a mix of industry and government
sources. Funding sources for the recovery
boiler research include Weyerhaeuser, the
U.S. Department of Energy, Industry
Canada, and Energy Mines and Resources
Canada. The research project has already
spun off a company, Process Simulators,
which focuses on calculation for black
liquor recovery boilers.
Martha Salcudean, Associate Vice President
Research (Physical and Applied Sciences).
UBC was awarded several research
contracts as part of the project to investigate
flow fields in recovery boilers. "We are in
the process of transferring technology to
boiler manufacturers and pulp and paper
companies," said Salcudean. But their work
is far from finished. They will spend the
next year and a half working on a global
recovery model which includes combustion
and chemistry.
For Salcudean, and many other UBC
researchers, industrial collaboration is not
only rewarding, but gives them access to a
wider range of funding sources. According
to CICSR director James Varah, "If you
look at funding levels over the past several
years, this is where all the new money is
going. I believe it's part of a federal
government strategy to force the marriage
between university researchers and
industry. I've seen it working."
Both Varah and Salcudean have noted that
both companies and university researchers
are becoming more and more amenable to
working together. "It's amazing the
acceptance level in the universities now,"
said Varah. "There is no stigma attached to
working with industry. In fact, it's the
opposite. Industrial collaboration is now
seen as a good thing to do." ■ CITR Helping Canadian Telecom Compete
The work of the Canadian
Institute for Telecom Research
will help maintain Canada's
competitiveness in telecom.
■ The telecom industry is one of the
strongest industry sectors in Canada, and
the Canadian Institute for Telecom Research (CITR) was created to make it even
stronger, according Dr. Robert Donaldson,
Department of Electrical Engineering Head,
and leader of a CITR project area.
CITR is a nationwide project, with participants from 15 universities and two research
institutes. CITR recently had its funding
renewed for the second phase of the
program to the tune of about $4 million per
year. To qualify for the funding, a network
must have excellent research and personnel,
must make use of networking and partnerships, and there must be strong potential for
knowledge exchange and technology
exploitation. This is yet another research
funding program that requires research that
will lead to commercial exploitation and
contribution to economic growth.
Part of CITR's strength is its strong
representation from industry. About half of
the members of the board of directors are
from industry. CITR projects are not
approved by the board unless they have
high academic quality, plus industrial
CITR is divided into five major project
areas that, combined, will boost the
Canadian telecom industry into the next
generation of technology. The project areas
include: broadband networks, broadband
services, photonic systems, mobile and
personal communications, and broadband
indoor wireless communications. Within
each major project area are a number of
individual projects.
Donaldson's own research falls in the
mobile and personal communications
project area. Entitled "Internetworking of
wireless communication networks," the
project's objective is to find ways to
interconnect wireless networks with each
other, with broadband networks and
services and with people-on-the-move. The
project is relevant to at least three other
major project areas, demonstrating the
interaction among major projects.
"When CITR was reviewed by a panel of
experts prior to phase two, this project was
seen as an important and essential component of the whole program," said
Donaldson. The review took place last
Dr. Donaldson, with one of the many researchers in the CITR network, Electrical Engineering Masters student William Wong.
summer, and phase two started April 1 of
this year. Of the 15 original networks of
excellence, ten were renewed, five in
engineering, five in medical research. Of
the five engineering centres, the UBC
department of electrical engineering is
participating in four, a claim no other
department in the country can make.
As part of his CITR research, Donaldson is
studying new and different approaches to
interconnecting wireless networks. Currently wireless networks are connected via
radio-based site controllers to broadband
networks in a highly centralized fashion.
The problem with this architecture is that
the network traffic associated with the
corning microcellular communication
devices is expected to be so heavy that a
centralized architecture will not be effective.
Donaldson and his research team have
analyzed a distributed switching architecture, and are comparing the cost and
performance of it against a centralized
system. However, the question about which
system is preferred will not be answered
just by looking at technical issues. There
are economic considerations, and strong
competition for control of the communication networks of the future. Telephone
companies may prefer to stay with existing
centralized architectures, while others in the
communications arena, including cable
companies, may prefer new, distributed
Donaldson and his colleagues prepared a
report and journal paper about a distributed
switching architecture which interconnects
radio-based site controllers via metropolitan
area network (MAN) rings, which are
bridged to each other, and to broadband
networks. This scheme was compared to an
ATM-based centralized switching system.
"There is a lot more interest in a distributed
scheme now, in part because of the work
we've done and published," said
The analysis that was done looked at voice
communications only. Over the next four
years, Donaldson and his research team will
study the implications for video, fax and
data communications traffic as well. "I
cannot overemphasize the complexity of the
project," he said. ■ A Better Way to Handle Fish
CICSR researcher Clarence de Silva looks at ways of making
Canadian fish processing more competitive.
Clarence de Silva is working with the fish processing industry to develop better processing machines.
■ The research of Clarence de Silva is a
perfect example of how research funding
sources are putting more weight on projects
that are not just academically interesting,
but beneficial to industry as well. According to de Silva, who holds the NSERC and
B.C. Packers chair, his research program
was established for the sole purpose of
making the Canadian fish processing
industry more competitive.
"They started by asking B.C. Packers for
their priorities," said de Silva, who is a
member of the UBC Department of
Mechanical Engineering. B.C. Packers, and
the industry in general, wanted better
recovery in salmon processing. When the
heads are cut off salmon prior to further
processing, a lot of meat is thrown out with
the head. De Silva and his research team
have since developed a complex cutting
machine that reduces waste to less than one
percent. With previous methods, five
percent waste was typical, and each
percentage of waste costs the industry $5
million per year. The economic benefits of
de Silva's new machines are obvious.
To date, de Silva and his team have built
one research prototype and one industrial
prototype. The machines use a vision
system to analyze the fish, robotics to
position, hold and cut them, and a sophisticated computer system to perform complex
calculations on the fly. De Silva said that at
first he was concerned about the speed of
the vision system. It has to be very fast,
since to be competitive, the machines must
process two fish per second. Faster image
processing hardware and improved
algorithms have enabled the research team
to speed the process.
De Silva is now working on adding
intelligence to the machines by adding an
intelligent control system that is "like a
supervisor watching over each machine."
The system takes sensory information such
as speed of the conveyor, force exerted on
the blades, cutting position, and blade
speed. Another part of the system looks at
the end product to analyze the smoothness
of the cut, depth and other factors needed to
evaluate the process. All of this information
is compiled and sent to the electronic
"brain" of the system, which uses the
information, and its knowledge base, to
make decisions, such as: Should the
conveyor be slowed down, or sped up?
Should the blades have more power? Or is
something drastically wrong that would
require a complete shut-down?
"The knowledge base decides on the
adjustments," said de Silva. "They could
involve simple parameter adjustments in the
software, or physical changes, such as
adjustment of the conveyor speed." The
information is also useful after the fact, to
determine the quality of the batch processed, and help determine its price. The
intelligent control system is now installed
on the research prototype at UBC.
"There is no end to the uses for that type of
system," said de Silva. "The same ideas,
with a new knowledge base, could apply to
many different applications."
For example, de Silva and his team are now
working on an expert system for grading
herring roe. The resident expert at B.C.
Packers currently has to train people each
year — the job requires a high degree of
skill, and is not a pleasant task. The
automated grading system could not only be
used for the grading itself, but also to train
new graders using the knowledge base
provided by an expert. So far, de Silva and
his team have developed the shape and
colour analysis part of the system. Next in
line is ultrasound to gauge the texture of the
roe, and the decision-making system.
Both the herring roe grading system and the
salmon cutting machine have considerable
commercial potential. A five percent
improvement in grading accuracy could
save the B.C. herring roe industry about $3
million per year.
According to de Silva, B.C. Packers is now
negotiating with a company to build
commercial prototypes. However, the actual
commercialization of the research does not
concern him. The fact that his work has
such strong commercial potential is due to
the industrial focus that was there from the
outset. In fact, in the past year, B.C. Packers
has doubled its funding in de Silva's work
to $120,000 per year, while NSERC has
reduced its contribution.
De Silva also receives funding from other
sources as well. He holds a B.C. Advanced
Systems Institute Fellowship, and his
herring roe project has been funded by the
Science Council of B.C. Both organizations
require a strong industry connection as a
prerequisite to funding. The Institute for
Robotics and Intelligent Systems (IRIS) has
also provided a four-year grant to finance a
project on sensor-based robotics.
The IRIS project will involve research into
the use of fuzzy logic to provide a higher
level of "feeling" and control in the fish
processing and roe grading equipment.
Other researchers in universities across
Canada are working on other sensory
aspects of robots as part of IRIS.
"I'm not working in isolation," said de
Silva. "Networking is one of the goals."
And, increasingly, another of the goals of
research funding bodies is to encourage
research that will have some industrial
benefits down the road. ■ Co-op Provides Hands-On Education
UBC science and engineering co-op students receive training in job skills, course material... and life.
■ One of the earliest forms of university-
industry collaboration in a researcher's life
may well be experience in a co-operative
education program. UBC has strong cooperative education programs in many of
the engineering and science disciplines, and
these programs benefit participating
students, companies and faculty alike.
According to Doug Olivers, the Mechanical
and Civil Engineering Programs Coordinator, there are more than 1,600 companies
from around the world participating in the
co-op program. The companies cover the
complete spectrum, from large multinational firms to small start-ups.
Chivers tries to encourage his co-op
students to work for as many different types
of companies as possible, so they have a
clear idea what they want before they
graduate and move into the work force.
Stephanie Moroz is an engineering physics
co-op student now working at TRIUMF.
She said, "I definitely wanted to experience
working at different places before graduating." In a sense, she says, co-op is more
than simply an academic education — it's
also an education in life: in getting a job,
living on your own, and learning to function
in a work environment.
For the companies, the co-op program
provides access to skilled employees for

projects of short duration, and provides an
excellent, risk-free means for them to try
out and recruit new staff. According to
Chivers, it's not uncommon for co-op
students to be hired after graduation by
companies they worked for while in the coop program.
Co-op at UBC has almost 200 engineering
students, and about 130 science students.
The co-op disciplines include chemical,
civil, electrical, and mechanical engineering
as well as engineering physics, computer
science, and physics. New co-op programs
are being established in statistics, microbiology/biotechnology and metals and
materials engineering.
According to Javed Iqbal, Science and
Engineering Physics Programs Coordinator, "We don't have co-op programs
in all the sciences, but we're slowly
bringing them on board." He'd like to see
students in all scientific disciplines have
access to a co-op education.
Mike Procter and Chris Waterman are two
of five UBC co-op students currently
working at CREO Products in Burnaby,
which is the first company in the world to
develop a direct-to-plate imagesetter for the
printing industry. Waterman, an electrical
engineering student, said he felt lucky to be
at CREO at a time when he could become
involved in such world-leading research. He
is doing two work terms at CREO, spending
eight consecutive months at the company.
Procter, a mechanical engineering student,
says there's a huge amount of knowledge
he's picking up at CREO that he simply
couldn't learn in the classroom — things
like machining skills, knowing where to
find components, and interpersonal skills.
"Experience is half the battle," he said.
"And it sure beats waiting on tables." Co-op
students all say they find it very gratifying
to be working in jobs that are directly
related to their studies, rather than doing
work during the summer that requires little
skill or training.
The co-op program provides students with
real-world experience, so that by the time
they graduate, they have a clear idea what
kind of work they can do, given their
education. "They are able to make an
informed choice about what they want to
do," said Iqbal. "Co-op can also make
students more motivated."
As the students in the co-op program
discover, there is more than one way to
learn science and engineering concepts.
"You can gain valuable knowledge working
in industry, which complements classroom
education," Iqbal points out. 'Traditionally,
in North America, the education system has
focused on classroom-based learning, with
less emphasis on work-based learning, but
things are changing." There is now increasing emphasis on practical, hands-on
education as well.
The UBC co-op co-ordinators, participating
companies and students would all agree that
this is a good thing. ■ IRIS Network Builds Better Robots
The Institute for Robotics and Intelligent Systems (IRIS) is developing the next
generation of intelligent systems — robots that will work in unpredictable environments.
The world of robotics is changing. Early
robots were designed to work in very
specific, and very controlled environments.
But the real world isn't predictable, and the
design of robotic devices to work in the real
world requires a whole new approach.
CICSR member Dr. Alan Mackworth of the
Department of Computer Science leads a
research project that will help to solve some
of the complex problems associated with
developing robots that can react to their
environment, even when it's changing in
unpredictable ways. The project, called
Constraint-Based Visual Robotic Systems,
is part of the larger project within the
Institute for Robotics and Intelligent
Systems (IRIS).
IRIS is one of the ten Networks of Centres
of Excellence (NCE) that has made it to the
second phase. UBC researchers involved in
the network will receive a total of $3.3
million over the next four years to develop
the robotic systems of the future. IRIS is
divided into five main project themes:
intelligent computation, machine sensing,
Dr. Alan Mackworth, with one of the many
robots developed as part of the IRIS network.
human-machine interfaces, advanced
medical devices, and integrated systems in
dynamic environments (ISDE).
ISDE, the theme which Mackworth's
project falls into, is a key area within IRIS
because its role is to find ways to integrate
the various technologies and find ways to
make them work well together in complex
robotic systems. According to Mackworth,
IRIS is a very diverse research network,
which includes researchers with very
different views about robotic systems.
Mackworth views this diversity as a very
good thing. "The integration of the various
technologies — including artificial intelligence and engineering-based control
systems — is causing us to change our
scientific views," said Mackworth.
One of the basic things that's changed
within IRIS as a result of the past few years
of research is the approach taken to
developing robotic systems. The widely-
accepted definition of a robot is a system
with a front end that perceives its world, a
reasoning part that plans its actions, and an
active, mechanical part that carries out a
task. "In the first phase of IRIS, we carried
out research into those three categories, but
there were not projects to integrate the
systems. Phase two of IRIS will take an
integrated systems approach."
The objective of Mackworth's specific
project is to develop new techniques for
responsive vision on mobile platforms in
dynamic environments. The researchers,
Jim Little, David Lowe, Dinesh Pai, Robert
Woodham and Mackworth plan to deliver
practical tools for building constraint-based
visual robotic systems. Vision systems for
monitoring and controlling the robot plant
and the environment will be built for
various testbed platforms, including visual
telerobotic control on machines currently
used in the resource and construction
industries. Other areas of research will
include 3-D vision, real-time systems
integration software, new techniques for
deformable surface visual interpretation, a
symmetrical vision platform, and the
development of complete, integrated
constraint-based visual robotic systems in
several realistic dynamic environments.
As part of the project proposal, Mackworth
provided considerable detail on the
potential economic impact of the research, a
key factor NCE considered in its renewal of
funding. In terms of industrial collaboration, the project team plans to work with
several companies that have an interest in
various aspects of robotic systems. For
example, the team will work with Kinetic
Sciences of Vancouver to develop real-time
vision systems for application to space and
terrestrial robots. They will also interact
with MacMillan Bloedel Research, Spar
Aerospace and RSI Research through their
collaboration with CICSR member Peter
Lawrence's project on Partial Autonomy on
Mobile Machines. Mackworth and his team
also work with CRS Plus of Hamilton,
Ontario, Xerox PARC, Traquair Data
Systems, Cognitiative Systems, and
International Submarine Engineering of
Port Coquitlam, B.C.
"As part of our proposal, we were required
to get industrial support," said Mackworth.
This support will become more important to
the project as it progresses, because NCE
funding levels drop in the final two years,
and the team is expected to make up the
shortfall through contributions from
industry. In the first two years, NCE will
provide UBC IRIS researchers with more
than $900,000 per year; in the last two
years, funding is about $750,000 per year.
Mackworth is one of several UBC researchers involved in the IRIS network. Other
participants include: Peter Lawrence of
Electrical Engineering, who heads the
project within ISDE on partial autonomy in
mobile machines; Tim Salcudean of
Electrical Engineering, who is working on
medical and micro robots in the Advanced
Medical Devices area; Max Cynader, who
is developing an effective display system
for teleoperator control of remote environments; and Robert Woodham of Computer
Science, who is heading a project to develop
content-based analysis and abstraction for
visual information management.
All of these projects, along with those being
tackled by researchers in other universities
and within research institutions and
companies across Canada as part of IRIS,
combine to advance the capabilities of
robotic systems, and to enable these
systems to work more autonomously, and in
dynamic environments. This research will
help bring robots into the real world, and
will vastly increase the ways they can be
put to work within industry. ■ ASI: Institute Without Walls
A closer look at the B.C. Advanced Systems Institute
■ One of the major catalysts for university-
industry research within B.C. is the B.C.
Advanced Systems Institute (ASI). ASI has
a number of programs, all of which are
aimed, directly or indirectly, at fostering
increased collaboration between university
researchers and industry.
The program CICSR has the greatest
involvement in is the Fellowship Program.
Currently UBC has 15 ASI fellows. All
fellows are CICSR members working with
industry. ASI has spent some $2.7 million
to support the research of UBC Fellows, but
ASI executive director Brent Sauder
strongly states that ASI should not be
viewed as a funding body.
"We should be viewed as facilitators in
bringing researchers and industry together,"
said Sauder. "We take requirements stated
by industry and we put the right teams
together to solve their problems."
ASI support often leads to other funding,
noted Sauder. A recent study showed that
for every ASI dollar spent at UBC, an
additional $2.70 was raised from other
sources. UBC was found to excel in the use
of graduate students and in collaboration
with industry.
UBC's 15 current Fellows, include Kellogg
Booth, Ian Cumming, Clarence de Silva,
Guy Dumont, Alain Fournier, David
Forsey, Mark Greenstreet, Andre Ivanov,
Nicholas Jaeger, Jeff Joyce, Takis
Mathiopoulos, Dinesh Pai, Septimiu
Salcudean, Carl Seger and Jack Snoeyink.

To qualify for a Fellowship researchers
must be doing excellent research in
advanced systems: information systems,
telecommunications, microelectronics or
robotics. The work must also point towards
a current or future solution to an industrial
ASI's mission is "to ensure that advanced
systems technologies are developed,
commercialized and used to aid in the
growth of B.C.'s economy. The mission is
achieved by providing solutions to industry's current and future technical needs by
facilitating interactions between industry
and post-secondary institutions. ASI is an
institute without walls in that its research
programs are conducted at the most
appropriate site, be that in industry or at a
In addition to the Fellowship program, ASI
has a number of other programs to help it
realize its mission. One that CICSR
members are taking advantage of the
Industrial Partnership Program. This
program is for companies that need
university research assistance on a problem
that can be solved in less than a year. ASI
provides the contacts and 50 percent of the
required funding.
Another program, the Industrial Fellowship
Program, has enabled CICSR's Jeff Joyce to
work at Hughes Aircraft investigating
possible applications of formal specification
techniques. Farrokh Sassani is a recent
addition to the Industrial Fellowship roster.
ASI also has programs in place for longer-
term projects with advanced systems.
Focusing on multi-year projects, these
programs share the attributes common to
other ASI programs: they are industry-
driven and promote personal contact
between industry and academic staff.
Other programs, not directly tied to
university researchers, but often linked,
include the ASI Affiliate Program, aimed at
companies that want to benefit from the
work of ASI, and the Product Development
Fund, which provides development funds
for advanced systems projects in the final
commercialization stage. As well, ASI's
industry-driven Focus Fellowship Program
has provided $105,000 in support to the E-
GEMS project involving UBC researchers.
ASI is funded by the B.C. Ministry of
Employment and Investment, and by its
industry partners. Its lean organizational
structure consists of an executive director
and a staff of two. But this small group has
been able to accomplish big things in terms
of university-industry collaboration. ■
■ The National Research Council and
UBC have established a new institute at
UBC. The Institute of Machinery
Research (IMR) develops technical
solutions to machinery design, operation and maintenance problems faced
by Canadian Industry, and will support
collaboration in machinery research by
NRC, UBC and industry. ■
■ Mechanical Engineering professor
Farrokh Sassani has been awarded a
Visiting Industrial Fellowship from the
B.C. Advanced Systems Institute. His
fellowship is in collaboration with
DynaMotive Canada Corporation of
Vancouver. Sassani is working on the
design of a computer integrated steel
rod handling system and controls for an
innovative continuous electrolytic descaling process. ■
■ Science Council of B.C. has announced that funding for its Technology B.C. program has been increased to
$6.5 million from $4.3 million.
Tech B.C. provides funding to both
university and company-based research,
but an industrial component is required
for funding. The program has funded
the research of several CICSR members, including, most recently, the work
of Ian Yellowley, Tim Salcudean and
Cyril Leung. ■
■ Faculty of Commerce and Business
Administration, MIS Division faculty
members Izak Benbasat and Robert
