Since the
advent of
1970’s,
control
of mechanical
manipulators
has been
an active
area of
research.
Many decentralized
and centralized
control
techniques
were developed
to control
non-linear
dynamics
of mechanical
manipulators.
These techniques
range from
“proportional,
integral,
derivate”
(PID) control
used for
each degree
of freedom
to computer
torque control,
which requires
the precise
knowledge
of the system
model. These
techniques,
when used
in conjunction
with operational
space control
in a time
variant
system,
result in
a much larger
error as
errors in
joint space
maps non-linearly
onto operational
space.
Using the
recent development
in model
prediction
algorithms,
a set of
novel direct
adaptive
controllers
will be
presented
in this
presentation
to control
serial and
parallel
manipulators.
The methodology
treats the
mechanical
manipulator
as a black
box, and
no prior
knowledge
of the dynamics
of the manipulator
is required.
A subspace
predictor
is first
evaluated
for a subset
of given
operational
space of
the manipulator.
A cost function
is formulated
using this
predictor,
which is
then optimized
for different
cases of
manipulator
control
using. This
approach
provides
a strong
mathematical
foundation,
which has
many applications
in other
engineering
problems.

Books
have been
a traditional
source of
knowledge.
From ancient
times to
present
day, books
play a major
role in
the scholarship
of society.
However,
even with
modern printing
facilities,
collecting
a large
collection
of books
is not possible
because
of physical
space restrictions.
However,
in the cyber
world especially
after the
widespread
use of the
Internet,
there is
now a possibility
to collect
virtually
all books
that the
world contains
at one place.
This place
is called
Google Books.
During the
past few
years Google
Books has
partnered
with hundreds
of libraries
and publishers
to put up
as many
books as
possible
on the Internet
and make
them available
to the masses.
How Google
is achieving
this mammoth
endeavor?
What it
takes it
to build
the world's
largest
book collection
and how
one can
really make
use of this
service
effectively
are some
of the questions
that will
be discussed
in this
talk.

Complex
(dusty) Plasmas:
A Challenging
Research Area |
|
October 29,
2009 |
|
|
October 29,
2009 |
| |
| Dusty
plasmas
are open
systems
of plasma
(electrons,
ions) and
dust particles
(typically
micron size
grains)
where the
sink of
plasma particles,
due to absorption
on dust,
is balanced
by a plasma
source.
These are
uniquely
informative
in low-temperature
laboratory
discharges
as well
in near
earth environment,
planetary
rings and
interstellar
space where
these are
ubiquitously
found. However
such micron
sized dust
particles
are an annoyance
in the plasmas
of fusion
energy and
semiconductor
manufacturing.
The grains
can be charged
negatively
and positively
by several
mechanisms
depending
on the local
plasma conditions
and radiation
sources.
Furthermore,
in the presence
of an ensemble
of charged
dust grains,
there are
collective
dust plasma
interactions
featuring
novel phenomena
e.g. waves,
instabilities,
coherent
nonlinear
structures
etc.
Dusty
plasma physics
has appeared
as one of
the most
rapidly
growing
fields of
science,
as demonstrated
by the number
of published
papers in
scientific
journals
and conference
proceedings.
In this
talk, the
basic physics
of dusty
plasmas
as well
as some
collective
processes
will be
discussed.
The focus
will be
on the charging
mechanisms,
formation
of dust
atoms and
molecules,
nonlinear
Landau damping
of helicon
waves and
lower hybrid
cusp soliton.
It appears
that collective
processes
in a complex
dusty plasma
would have
excellent
future perspectives
in the twenty-first
century,
because
they have
not only
potential
applications
in interplanetary
space environments,
or in understanding
the physics
of our universe,
next generation
ITER devices
but also
in advancing
our scientific
knowledge
in multidisciplinary
areas of
science.

The
weak Force and
its manifestations
at the Galactic
level |
|
October 15, 2009 |
|
| October 15, 2009 |
| |
|
Weak
force is the second weakest
force in nature and has the
shortest range. As such its
presence is felt only in the
microscopic domain. Yet the
manifestations of weak forces
are not only present in the
macroscopic world but also
at the galactic scale. Death
of stars, of the core material
of stellar cores and formation
of heavy elements are few
of the key signatures of weak
forces. Weak forces are also
involved in providing us information
about the age of the galaxy
and of the universe. In this
short presentation I will
present a brief overview of
the fundamental forces focusing
primarily on the weak force.
I will then discuss supernova
physics which is vital for
the existence of life. The
presentation will end with
a question/answer session
that will hopefully encourage
young minds to choose research
as a career in the fascinating
field of nuclear astrophysics.

Displays |

Flat
Panel Displays have become
an integral part of our lives.
These are everywhere from
wristwatches to the TV screens
at our home to the mobile
phones in our packets and
to the billboards on our streets
to name a few. In this lecture
we would look at the different
technologies that make these
displays possible with special
emphasis on LED backlight
based LCD displays. How do
these display technologies
compare and contrast? And
more importantly, what are
their environmental impacts.
We would also be looking at
the role different light management
films (BEF, diffusers, reflectors,
etc.) play in these displays.
Finally we will have a look
at the new and upcoming technologies,
which are going to shape our
future viewing.

LUMS School of Science and Engineering
is proud to announce that one
of its own, Professor Khalid
Aziz, received the Honorary
Doctor of Laws Degree from the
University of Calgary at their
Convocation Ceremony held on
June 9, 2008. This degree, the
highest academic honor conferred
by the university, was in recognition
of Dr. Aziz's contributions
to the Schulic School of Engineering
at Calgary and also an affirmation
of his world-renowned authority
in the field of petroleum engineering.
He was chosen for this honor
by the collective endorsement
of the senators, students, faculty
and staff of the University
of Calgary.
Dr. Aziz was a faculty member
at the University of Calgary
from 1965 to 1982. He laid the
groundwork for their highly
successful Bachelor of Science
Degree in Oil and Gas Engineering.
He was also responsible for
mentoring students who are now
industry leaders not only in
petroleum engineering but also
its related fields. "Khalid
Aziz has touched the lives of
essentially every petroleum
engineer who has graduated from
universities in all corners
of the world over the past half
century," said Dr. Elizabeth
Cannon, Dean of the Schulich
School of Engineering. Speaking
at the Convocation, Dr. Aziz
emphasized upon the need for
creating socially conscious
leaders. He encouraged the students
to, "Look for opportunities
to serve in meaningful ways,
not just at home," he urged
the graduates. "You have the
skills to tackle problems around
the world."
Dr. Aziz is recognized around
the world as an expert in reservoir
simulation, modeling of advanced
wells and natural gas engineering.
He has written two books and
over 200 technical papers. He
has made an impact in the business
world as well. His company Computer
Modeling Group (CMG) is one
of the world's leading suppliers
of reservoir modeling and simulation
software. It has a client base
of more than 200 oil companies
and technology centers in 42
countries.
Dr. Aziz currently has a joint
appointment at the LUMS School
of Science and Stanford University
as a professor of energy resources
engineering. Similar to his
role at the University of Calgary,
Dr. Khalid Aziz has been intimately
associated with LUMS SSE from
inception to date. As a member
of the advisory board at LUMS
SSE he has made valuable contribution
in all aspects, from academic
to administrative. His knowledge
has influenced matters such
as faculty hiring, curriculum
development and other allied
aspects. One can truly say that
he has left everlasting impression
in every conceivable facet of
the SSE. LUMS SSE hopes to continue
benefiting from his reservoir
of knowledge in the future as
well.
