<H1 ALIGN=CENTER>Financial Aid</H1>

<P>The application form for admission to graduate study includes a place to
specify whether you want financial aid or not.  Most financial aid consists
of research assistantships, teaching  assistantships, or fellowships.

<H2 ALIGN=CENTER>Assistantships</H2>
<table><tr><td valign=top><p>
Approximately 48 teaching assistantships are available.  First-year
teaching assistants normally conduct laboratory sections of introductory
computer science courses, and second-year students usually help in
upper-level courses, mostly as graders.  Teaching assistantships usually
cover only the academic year, but a few assistantships are available during
the summer as well.

<P>Approximately 130 students are supported by graduate research
assistantships on research grants and contracts.  This usually allows work
which leads to the student's thesis or dissertation topic.  Most faculty
members currently have research grants, and the department's research
budget is stable.

<P>Current stipends range from $9,900 to $13,437, depending upon a graduate
assistant's educational background and experience and whether the stipend
is for ten or twelve months.  In addition, assistantships cover tuition for
up to 10 credits per semester and provide health insurance coverage under the
University benefits plan.

<H2 ALIGN=CENTER>Fellowships</H2>

<P>In addition to assistantships, fellowships are available for students
who are particularly talented or who satisfy special qualifications.
Unlike assistantships, fellowships usually do not require the student to
perform any particular duties.  The monetary award varies depending on the
fellowship but is generally similar to the amount of money provided by an
assistantship.  The department may supplement fellowships by offering the
student one-half of an assistantship in addition to the fellowship.

<P>Within the University of Maryland, fellowships are available from
UMIACS, ISR, and the Graduate School.  To apply for these fellowships,
indicate that you need financial aid when you fill out the application for
admission and complete the Merit Based Financial Aid form.  The department
will nominate the best-qualified applicants.  Instructions on how to apply
for the ISR fellowships are available separately.

<P>A number of fellowships from outside of the University of Maryland are
also available.  For example, several of our students have had National Science
Foundation Graduate Fellowships, Fulbright Fellowships, or other
fellowships.  To apply for such fellowships, you should contact the agency
which administers them, check with the financial aid office in your current
university, or contact the Fellowship Office at the University of
Maryland.

<P><HR>

<H1 ALIGN=CENTER>Degree Requirements</H1>
<table><tr><td valign=top><p>
Below is a summary of the graduate degree requirements.  Details are available on request from the Computer Science Department Graduate Office.  For full-time students starting with a B.S. degree, it usually takes 1-1/2 to 2 years to complete the M.S. degree and 5 years to complete the Ph.D. degree.

<H2 ALIGN=CENTER>Master Of Science</H2>

<P>The department offers both thesis and non-thesis options for the Master of Science (M.S.) degree.  The following requirements apply to all M.S. students:

<OL>
<LI><STRONG>Coursework.</STRONG> Students must complete at least 30 credit hours with an average of B or better.  All courses must be at the 400 level or higher, with at least 18 credit hours at the 600-800 level.  At least 21 credit hours must be CMSC courses.
<LI><STRONG>Breadth.</STRONG> The coursework must include regular 600 or 700-level courses from four of the department's seven research groups.
<LI><STRONG>Transfers.</STRONG> No more than six credit hours may be transferred from another university or another program at UMCP.

Requirements for the Ph.D. degree include the following:

<OL>
<LI>Students must complete a <STRONG>10-course qualifying sequence covering five out of the department's seven research areas</STRONG> (at least one course in each area must be at the 600-800 level). 
<LI>Full-time students who have completed the qualifying sequence must meet Graduate School requirements with respect to the number of credits they take each semester.  With their advisors' consent, they may choose to register for regular courses, independent study, or dissertation research credits.  An overall average of B or better must be maintained.
<LI>Students must pass an oral <STRONG>Ph.D. Preliminary Examination</STRONG> on a research proposal and prepared readings, as well as demonstrate <STRONG>competence in a foreign language</STRONG>.

<H1 ALIGN=CENTER>Profiles of Faculty Research</H1>

<P>Research in our department covers almost all computer science fields.
The descriptions here are just a sample of research activities.

<P>Searching by content in multimedia databases examines fast methods
for approximate matching.  Typical queries are as follows:  "in a
collection of product photographs, find products that look like tennis
shoes;" "in a collection of medical X-rays, find ones that look like the X-
ray of the current patient and list the corresponding diagnoses."  The
main idea is to extract <I>n</I> features from objects of interest (typically, with
the help of a domain expert), thus mapping each object into a point in
<I>n</I>-dimensional feature space.  Subsequently, we can use state-of-the-art
database technologies (like 'R-trees') to store and retrieve these <I>n</I>-
dimensional points.  The philosophy is to provide a 'quick-and-dirty'
filter to eliminate the vast majority of irrelevant objects.  Some false
alarms are acceptable, because they can be easily discarded by an
elaborate test or even by the user.  We already have sets of features for
2-d color images, 2-d shapes, and 1-d time series.  We are
experimenting with modern signal processing techniques, such as the
discrete wavelet transform for sound and images with mathematical
morphology for shapes and with the discrete cosine transform for
stock-price time series.  The method is generic and can be applied for
ANY collection of multimedia objects, as long as there are some good
feature extraction functions.  Potential applications include:  1) Medical
databases:  For diagnostic, research and teaching purposes, patient
records can be supplemented with electrocardiograms, X-ray images,
MRI scans, etc.  2) 'Edu-tainment':  Students, researchers, and video-on-
demand customers can search databases of video clips, art images, etc.
3) Scientific databases:  Collections of NASA photographs, of
meteorological/geological maps, etc. can be used to aid in forecasting
weather, etc.  4)  Electronic commerce:  Users want to search electronic
catalogues with product photographs, in addition to other attributes
(price, maker, availability, etc).

<P>In Spring 1995, Dr. Keleher won an NSF CAREER award, which will
fund research on high-performance synchronization in distributed
systems.  Software distributed shared memory (DSM) systems provide
the abstraction of shared memory to networks of workstations and
distributed memory machines such as the Paragon, CM-5, or SP-2.
Unfortunately, the latencies for global operations in either
environment are several orders of magnitude more expensive than on
tightly-coupled multiprocessors.  The result is that current DSMs
perform well for only a restricted class of applications.   Sparks, a
protocol construction library that will allow improved performance of
DSM systems to within a few percent of tightly-coupled
multiprocessors, is currently being designed.  Sparks' abstractions will
allow clean and systematic explorations of the design space of high-
level synchronization operations, rather than proposing and
implementing new operations in an ad hoc fashion.  Sparks' basic
abstraction is the coherence "history," an object that summarizes past
coherence actions to shared segments.  The emphasis is more on
creating and investigating the abstractions that make a broad variety of
optimizations possible, rather than on the individual optimizations
themselves.  However, the performance gains allowed by the
synchronization types created via the Sparks library will be thoroughly
quantified.
