Deterring Cyber Pirates and Detecting Cancer Genes
Electrical and Computer Engineering professor Z. Jane Wang uses a multidisciplinary approach
to track digital thieves and cancer genes.
► Digital Fingerprinting
► Biomedical Imaging
► Genomic Sequencing
New ICICS member Z. Jane Wang's
research spans broad areas of statistical
signal processing, including applications
in biomedical imaging, genomic signal
processing and statistics, and digital
information security. Due to the ease
with which digital content can be
accessed, retrieved, manipulated,
reproduced, and redistributed, the
demand for methods that will protect
multimedia from piracy continues to
escalate as Wang searches for a solution.
Digital Multimedia Forensics
Digital fingerprints are signals
embedded in media data to protect
digital rights and prevent illegal
distribution and usage. Though it
does not prevent copying, a digital
fingerprint can trace unauthorized use
back to a specific identifiable user.
For example, the American Academy
of Motion Picture Arts and Sciences
sends screening copies of nominated
films to Academy members for
voting purposes.

Welcome to the Spring 2006 edition of
FOCUS. In this issue you will read about
the novel collaborations of ICICS members
in the Data Communications Group. Their
work in wireless communications addresses
the numerous challenges of advanced wireless
systems, including balancing the demand for
increased data rates and convenience of use
with security, privacy and reliability. Specific
areas of expertise include the design of novel
transmitter/receiver structures for improved
performance; ultra-wideband (UWB)
systems; the development of emerging global
networks; and wireless sensor networks.
As Mathematics head and Information
Systems Lab member, Brian Marcus'
research in applied mathematics and
communications theory aids in the
quantification and transmission of digital
information and complements the work of
the Data Communications Group.
New ICICS and ECE member Lukas
Chrostowski works on the fabrication and
modulation of "very small lasers" (VCSELs)
used in the development of nano-based
optoelectronic devices for fibre optics, quantum computing and biomedical applications.
Computer scientist Michael
Friedlander's work in scientific computing
and optimization involves the design and
analysis of algorithms to help solve
large-scale problems in applied mathematics
and engineering.
ECE member Z. Jane Wang's research in
statistical signal processing has applications
in biomedical imaging and Parkinson's
disease, detection and prevention of cancer,
and digital multimedia forensics and security.
We hope you enjoy reading about the
exciting and innovative research of these
ICICS members.
Rabab Ward, ICICS Director
If
smbe
his
one member gives nis copy to a
friend, who illegally posts it on the
internet, then digital fingerprinting can
trace each copy back to the Academy
member to whom it was originally sent.
However, if several colluders join
together to manipulate media content,
such as by averaging their copies, the
tracing capability of digital fingerprinting is greatly reduced. Wang's challenge
is to design collusion-resistant digital
fingerprinting by building upon the
synergies between a number of
engineering areas, including
watermarking, cryptography,
multimedia processing,
signal processing, coding,
and information theory.
Biomedical Imaging in
Parkinson's Disease
Biomedical imaging is
used to study the relationship between brain cell loss and
clinical disability in Parkinson's
Disease (PD), in order to get a more
accurate picture of the disease's
progression. Normal and diseased
brain functioning differ by altered
patterns of dynamic connectivity
between brain regions. "We are
working to develop models to assess
connectivity using fMRI and EEG
on PD patients—specifically to
isolate the disease effects from
compensatory mechanisms, and to
determine the effects of medication
across several domains, such as brain
connectivity, motor activity, and
temporal dynamics," says Wang.
This new collaboration between
clinicians and scientists is a major
joint initiative between UBC, SFU
and the University of North Carolina.
Most of the research data is collected
from UBC's Brain Research Centre, in'
collaboration with Dr. Martin
McKeown, a clinical neurologist and
professor in the Faculty of Medicine,
and Dr. Janice Eng, Associate Professor,
School of Rehabilitation Sciences.
Genomic Signal Processing for
Detection and Prevention of Cancer
Microarray technology is at the
forefront of the fight against cancer.
It allows scientists to analyze the
expression of many more genes in a
single procedure than has traditionally
been possible. Assuming that information about cancer cells is contained in
that cell's genetic "expression"
(transcription of information in a cell's
DNA into messenger RNA), then the
ability to assay gene expression on a
larger scale can potentially lead to
earlier detection of the disease,
more accurate classification,
and better prediction of
outcomes.
"Many universities are
promoting the marriage
between science and
engineering. Genomic
systems will be the
mainstream of life sciences."
Wang is currently testing a model-
driven rather than a data-driven
approach to the classification of cancer
and normal samples, and identification
of cancer biomarkers based on
microarray gene expression data. She
incorporates engineering and modelling
tools to attempt to solve biology
problems at the systems level. This
new, multidisciplinary approach holds
great promise in disease detection
and treatment. Collaborators include
NIH researchers and Dr. K. J. Liu
at the University of Maryland.
"Many universities are promoting
the marriage between science and
engineering. Genomic systems will
be the mainstream of life sciences."
This multidisciplinary approach
particularly appeals to Dr. Wang.
"I always try to find some new area
where my expertise can be useful."

FOCUS Lassoing Light in Nano-Scale Lasers
Lukas Chrostowski develops nano-based optoelectronic devices for use in fibre optics,
quantum computing, and biomedical applications.
► Optoelectronics
► Nanofabrication of Lasers
► High-Speed Modulation
From laser surgery to supermarket
checkouts, lasers have become so
ubiquitous that we rarely think about how
much we rely upon them. Today, lasers are a
critical component of science and technology research, and for new ICICS member
Lukas Chrostowski, smaller is better.
Laser Clocking for Cool Switching
"Nano-based optoelectronic devices are
important in fibre optics, for future wireless
devices and for future high performance
computers," says Chrostowski. Building
increasingly smaller transistors for greater
chip density and computational speed poses
fundamental problems. In standard chips,
electrical impulses are distributed over a
wire grid, and this metal interconnection,
which is premium on a chip, heats up.
With the power of microchips scaling exponentially as Moore predicted, in five or ten
years the temperature of chips would be so
high that they would melt. Clearly, alternative switching technologies are necessary.
Along with ICICS colleague Konrad
Walus, Chrostowski is developing optical
interconnects for a novel computing device
based on single electron interactions in
quantum dots (semiconductor nano-
crystals). Their goals are to replace the wire
grid with a laser-based clocking and data
interconnect network, and replace current
CMOS transistors with single electron
devices. Both would be faster and use far
less energy.
VCSELs—Very Small Lasers
The nano-scale lasers used in this
project, called Vertical Cavity Surface
Emitting Lasers or VCSELs, are the
cornerstone of Chrostowski's research.
VCSELs are 1,000 times smaller than
conventional lasers and a million times
smaller than tabletop lasers (photo).
Thus, they need to be fabricated
in a clean room, such as the
nanofabrication facility in AMPEL at
UBC, using tools such as scanning
electron microscopes.
Laser modulation is a key aspect of
Chrostowski's work. He and ICICS
colleague Nick Jaeger (ECE) are working
toward single-wavelength devices capable of
being modulated in the 10s of GHz range.
A smaller laser cavity has several advantages;
for example, it can potentially be turned
on and off faster. "The implications are that
the operating power is significantly
reduced, and you also get higher-frequency
operation," says Chrostowski. "A low-resonance frequency laser produces poor noise
characteristics, greater distortion and limits
how much information you can transmit."
The primary advantage of higher frequencies is the ability to transmit more information. For communications applications, the
resonance frequency is one of the most
important parameters, Chrostowski notes.
Continued on page 8
Spring 2006 Using Mathematics to Combat Noise
Mathematics head and ICICS member Brian Marcus uses mathematical tools to help
quantify and transmit digital information.
► Information Theory
► Error Correction Coding
► Communications Systems
Whenever and however we communicate
information, it is almost always in the
presence of noise. A conversation in a
crowded room, static on a telephone line,
poor cell phone reception, or deep space
transmissions interrupted by disturbances
are all examples. Brian Marcus is a
mathematician and member of the
Information Systems Lab—a subgroup
of the Data Communications Group.
Marcus works in the area of
information theory, which he describes as
"a branch of mathematics that quantifies
information and designs methods of
transmitting it reliably." In communication
and data recording applications, methods
of transmission that enable the receiver to
separate noise from information are critical.
"This is one of the most important places
where mathematics meets engineering,"
Marcus notes.
Putting Polynomials to Work
For centuries, mathematicians have
pondered solutions to polynomial equations.
This led to the development of abstract
algebra, which has blossomed into a broad
and profound theory over the past 200 years.
The last few decades have witnessed many
surprising applications of this theory, from
aerospace engineering to wireless
technology. However, the equations for
algorithms that encode and decode data
involve algebra that would not have been
envisioned centuries ago.
For instance, in error correction,
coding redundancy is built into the data
to help correct for errors, whether in data
transmission or storage. "If we think of data
transmission from one point in space to
another, then data storage can be thought
of as transmission from one point in time
to another," Marcus explains. "In either
case, we want to improve robustness."
Embracing Entropy
In the realm of information theory,
the concept of entropy has to do with how
much randomness there is in a signal and
how much information is carried by the
signal. "Given any kind of information
source, whether speech, video or computer
data, if there is a lot of uncertainty in what
you will see next given what you have
observed in the past, then we would say
that the information source is very rich,"
says Marcus.  "So, entropy is used as a
measure of information richness."
Speech is an example of a rich information source that is very hard to model. That
is why current speech recognition software
is often error-prone. Although the speech
recognition feature on Marcus' cell phone
works fairly well, it only needs to recognize
a couple of words at a time. To quantify
human speech requires breaking it down to
the smallest component, the phoneme.
However, when we talk, the shift from one
phoneme to the next can involve an infinite
variety of sounds (consider Eliza Doolittle
and Prof. Higgins).

FOCUS ECE's Data Communications Group
ICICS members in the Data Communications Group,
Department of Electrical and Computer Engineering, are
trailblazing wireless research and design.
Innovators in wireless technology still have several
challenges to overcome. They must balance convenience of use
with security and privacy, increased data rates with reliable
transmission, and limited bandwidth availability with the
need to support the varying demands of different traffic
types (audio, video, text, electronic transactions). "Each traffic
type has its own characteristics; so one of the things we are
trying to do is design systems and networks that will allow
us to carry all of these different types efficiently, reliably and
securely," says Cyril Leung of the Data Communications Group
and PMC-Sierra Engineering Physics Professor in Networking
and Communications.
Recognized as international
leaders in the field of wireless
communications, group members
also include ICICS members and
ECE colleagues Vijay Bhargava,
Lutz Lampe, Victor Leung, David
Michelson, Shahriar Mirabbasi, Robert
Schober, and Vincent Wong. With more
than 70 graduate students, evenly split
between the Master's and PhD
programs, the Data Communications
Group is one of the largest in ECE
and one of the most active in ICICS.
The group has received infrastructure
funding from the Canada Foundation
for Innovation and the Province of BC;
major funding from the Natural
Sciences and Engineering Research
Council (NSERC) of Canada, TELUS
Mobility, Bell Canada, PMC-Sierra;
and strong industry support from
across Canada.
Improving the Capacity of Emerging
Communication Systems
One aspect of the group's work is
design and evaluation of novel
transmitter/receiver structures for
improving performance in emerging
communication systems such as next-
generation cellular networks. This research
effort is aimed at enabling new, exciting
service provider offerings at affordable
costs to the customer. Current group
activities include Multiple Input Multiple
Output (MIMO) techniques, space-time
coding, coding techniques for collaborating users, multi-user detection, efficient
resource allocation in code-division
multiple access (CDMA) networks to
support various traffic types, and Quality
of Service (QoS) requirements and
propagation and channel modelling for
wireless communications system design.
Ultra-Fast, Ultra-Wideband Wireless
One major research project involving
most members of the Data
Communications Group is on ultra-
wide bandwidth (UWB) systems which
operate in the 3 to 10 GHz frequency
band. The project, led by Robert
Schober, a Canada Research Chair in
Wireless Communications, is funded
by government and industry. The
major advantage of UWB relative to
the existing Bluetooth wireless
technology is that it supports much
higher data rates, allowing high-speed
systems to transmit with extremely
low power over distances of five to
ten metres. The technology would
provide a short-range wireless link
for home, office and research
applications—virtually eliminating the
need for unsightly communications cables.
Designing an Emerging Global Network
"The future amalgamation of wireless
and broadband networks will enable
multimedia communications regardless
of location and mobility," says group
member and Telus Mobility Research
Chair Victor Leung, whose research is
focussed on the development of this
emerging global network.
One area of his work is packet-based
wireless networks, which allow better
management of data transmission,
including fluctuating data rates in
multimedia transmissions, and more
efficient use of bandwidth. "The
consensus in the industry is that over
the next five to ten years the access
and core networks will become all
packet-based, and different wireless
networks will provide access to
multimedia services in a manner that is
transparent to the users," says Victor
Leung. Anyone who has used Skype or
other voice-over-internet protocols (VoIP)
to talk to friends around the world has
experienced the benefit of packet-based
data transmission. Although current
mobile phones use digital networks, the
technology is still based on circuit
switches. "Service providers and
equipment manufacturers are now
trying to move cellular networks into
Voice-over IP technology."
Mobile Ad Hoc and
Wireless Sensor Networks
Applications for mobile ad hoc and
wireless sensor networks have grown from
primarily military to research and civilian
use, such as spontaneous networks, security surveillance, fire protection, avalanche
detection, and environmental and health
monitoring. An NSERC strategic grant
project, led by Victor Leung, is supporting the work of several members of the
Data Communications Group to develop
low-cost, energy-efficient wireless sensors
and the networks to support them.

FOCUS
Spring 2006 Optimization Algorithms for Colossal,
Complex Problems
Computer scientist Michael Friedlander designs, analyses and implements algorithms that solve
large-scale optimization problems in applied mathematics and engineering.
► Constrained and
Unconstrained Optimization
► Numerical Linear Algebra
► Scientific Computing
The junction of applied mathematics
and computer science is the tricky research
terrain that new ICICS member
Michael Friedlander traverses.
This field, called numerical
optimization, was developed in
the 1940s during WWII to handle
complex military logistics.
Friedlander is not interested in
working out the most efficient
way to route military supplies or
bomb U-boats, but his fundamental research in algorithms has
applications in a wide range of
disciplines—from imaging to
finance to resource allocation.
Doing the Best
with What You've Got
"The first step in my work is to
express a problem as a mathematical model
that describes the variables involved, the
constraints that must be satisfied, and the
objective to be achieved," he states.  It's
all about "doing the best with what you've
got" in order to solve real-world problems.
The second step—and Friedlander s
favourite part—is trying to solve the
resulting optimization problems, which
often carry constraints. In optimization,
constraints are any factors that limit the
ways in which a system can achieve its goal.
A good example is the computer-generated
face (see inset), which was created using
144 complete sets of dominoes. There are
only certain ways that the dominoes can be
arranged, so the optimization problem
is to find the truest reproduction while
following those rules.
Here is where unknowns come into
the picture. Sometimes thousands or
even millions of unknowns must be
juggled to achieve a goal. In nonlinear
problems like the ones Friedlander works
on, it is only possible to examine a little
piece of the puzzle at a time. "When
a function is nonlinear, you really
don't know how it is going to behave—it's
like poking around in a dark room with  ■
blinders on," he admits. "Sometimes we
don't even know if the problem is solvable."
For Friedlander, this kind of mathematics is
as much an art as a science and the joy is
really in the doing.

optimization course. ►    Chrostowski: Continued from page 3
Laser-Based DNA Detection
Chrostowski is planning to apply the
same laser technology for biomedical
applications, such as implantable glucose
monitors for diabetes patients, and for
biomedical microarrays, which use
fluorescence and spectroscopy to quantify
the presence and amount of DNA in a
sample. The essence of a microarray is to
measure thousands of cell sites containing
tiny volumes of DNA all at once.
What Chrostowski is working on is a
cluster of tiny lasers that illuminates the
entire array—one VCSEL for each dot of
DNA. The advantages of this technique
are universal applicability to any organism
of interest, quantitative analysis on a
per-cell basis, and higher signal-to-noise
ratio for more accurate measurements.
Hopefully it will be fast, precise, portable,
and cost effective.
The challenge of lasers for such
[tnophotonics applications is that they
have to be in the 300 to 500
nanometre—or ultraviolet—range and
require a new kind of material, gallium
nitride. "This is a novel area that is very
exciting," says Chrostowski. "It has a
multitude of uses in life science and health
research, and ultimately could be used in
common clinical settings to benefit
more people."
Lukas Chrostowski can be contacted at
604.822.8507 or lukasc@ece.ubc.ca
►   Marcus: Continued from page 4
"This is a natural example of
a rich information source that
you can only observe in the presence
of noise," says Marcus. Mathematicians
and engineers alike recognize the
example as a classic "hidden Markov
chain."
"One outstanding problem is to
compute the entropy of a hidden
Markov chain as a measure of the
richness of an information source,"
says Marcus. "This is something that
I am very excited about now."

►   Friedlander: Continued from page 7
Finding the Quickest Way
Down a Mountain
Imagine a constrained optimization
problem as a trek through mountainous
terrain, where the goal is to reach the
bottom of a particular valley as quickly as
possible, but only by using certain paths.
In algorithmic terms, this is called
convergence. Your quest would be easier
and more direct if you could start halfway
down, with the valley in sight. But
choosing your paths becomes much more
difficult if you are starting at an arbitrary
point somewhere at the top of a mountain
range, with no valleys in sight at all.
Friedlander devises methods that can
efficiently find feasible paths down to the
bottom of the valley without getting get
stuck along the way. "With these methods,
no matter where you start, they guide
you along toward a solution," he says.
Poking Around Plato's Cave
Although Friedlander s specialty
is devising and analyzing algorithms, he
also enjoys putting his ideas to work on
practical problems. Among his current
projects is a collaboration with UBC
geophysicist and ICICS member Felix
Herrmann on models for imaging what
lies beneath the earth's surface. Data for
these models is gathered indirectly, using
methods to drive sound into the earth and
then listening for echoes. Like the
inhabitants of Plato's allegorical cave,
researchers can't actually see direct images,
or even hear direct sounds. They build
the images they need from echoes and
reflections. This turns out to be a huge
optimization problem. The geophysical
Plato's cave is perfect terrain for Friedlander
to put his algorithms to the test.
