Absence:
A substantial portion of this class revolves around in-class
collaborative work. As emergencies do arise, you will be allowed
one unexcused absence, but you will still be responsible for getting
in contact with your peer group and/or completing the work for that
day. Each absence after that can bring your grade down 0.25 level.
Excused absences are allowed in cases of serious problems. In
order to receive an excused absence for an illness, you must notify
me before class time or bring official notification.
„
Completing Work:
In order to receive a passing grade in this course, you must
complete all of the work assigned during the semester. Late work

During the defense the committee looks for:
1.
Kasaei
Whether the candidate has a very good understanding
of the problem.
The candidate should be conversant with the relevant
literature, should explain how the proposed approach
is different, how practical the work is.
١٣٥

This study will consider why current solar energy
systems, such as Solar One, have not reached the
commercial stage and will find out what steps
we can take to make these systems commercial.
R.I.P.
The goal of this study is to develop a commercialization strategy for solar energy systems by analyzing
factors impeding early commercial projects (i.e.,
SOLAR ONE) and by identifying the potential actions
that can facilitate the viability of the projects.

The goal of the work was to
confirm the nature of electrical
breakdown of nitrogen in uniform
fields at high pressures and
electrode gaps which approach
those obtained in engineering
practice, prior to the determination of the processes which
set the criterion for breakdown
in the above-mentioned gas in
uniform and non-uniform fields
of engineering significance.
Kasaei
At high pressures (760 torr)
and typical electrode gap
distances (1 mm), the
electrical breakdown of
nitrogen was studied in

Examples anchor abstract generalities
By the late Middle Ages, cities throughout
Europe were building Gothic cathedrals. The
only way, however, that architects could test a
new design was to build the cathedral, a
process that took more than forty years.
Unfortunately, many cathedrals caved in during
or after construction. What took forty years to
test in the Middle Ages could have been done in
minutes on a supercomputer.

Mount St. Helens erupted on May 18, 1980. A cloud of hot rock
and gas surged northward from its collapsing slope. The cloud
devastated more than 500 square kilometers of forests and
lakes. The effects of Mount St. Helens were well documented
with geophysical instruments. The origin of the eruption is not
well understood. Volcanic explosions are driven by a rapid
expansion of steam. Some scientists believe the steam comes
from groundwater heated by the magma. Other scientists
believe the steam comes from water originally dissolved in the
magma. We need to understand the source of steam in
volcanic eruptions. We need to determine how much water the
magma contains.

Finding good review articles is like finding gold nuggets
during your literature review.
These are often published by Ph.D. students, who have

How does one make use of this great abundance of
research?
1.
Be selective in your choice.
Do not print all the articles on hard copy.
Download & store the papers you choose on your
computer & read them there if possible.
Papers that are very important to your research
probably should be printed out because most of us are
better able to handle detailed study of hard copy than
material on computer screens.

“publish or perish” syndrome
That is, if you are hired after graduation into a tenure
track faculty position, you will be required to turn out an
acceptable amount of research over a limited time, in
order to keep your job.
If you have a couple of good articles published or
accepted, by the time you complete your studies, this
greatly enhances the likelihood of finding a good
position.
