Mathematica Special Interest Group (Washington DC Area)

The Washington D.C. area Mathematica Special Interest Group will meet
Friday, 31 October, 7:30 to 9:30 a.m. at the SAIC Enterprise Center
building in Tysons Corner (see directions below).

Early risers meet before 7:00 in the morning for admission at the front
desk, then we have a Dutch treat breakfast downstairs.  By about
7:30 we have moved to one of the classrooms.  Meetings consist of
prepared talks, informal discussion about Mathematica programming and
applications, general questions, and new business. 

The prepared talks are:

"Eigenvalues and Eigenvectors Associated with Waveguides" by Mel Friedman.
The frequencies that are propagated by a rectangular waveguide and the
associated modes are explored analytically and numerically with
Mathematica. The frequencies that propagate through the waveguide and
the associated mode shapes are related to eigenvalues and eigenvectors
found using Mathematica. Although not done here, the numerical approach
could be extended to other geometries where analytical calculations are
not possible. This example illustrates a finite difference technique that
can be used to explore the properties of waveguides.

"DynamicModule Tricks" by Dan Martinez. Our local Mathematica magician
 will take us Trick 'o Treating through Mathematica's frightful swamp
 of dynamic programming.

Bruce Colletti will present "MathGroup Corner", a summary of the month's
highlighted traffic in MathGroup, a forum for Mathematica users

Bruce and Dan will recap last week's International Mathematica User
Conference.  You can also read the Champaign News-Gazette story
"Expansion Ahead" about Wolfram Research:

To inquire about attending, e-mail Dan Martinez (dmartinez at
or Bruce Colletti (bcolletti at  In your e-mail subject line,
please include 'Mathematica SIG.' 

The SIG-site is
DIRECTIONS to 8301 Greensboro Drive, McLean VA (tall, boxy and white
SAIC Enterprise Building at the corner of Westpark Drive and Greensboro
Drive):  From the Beltway, go northwest on Route 7 (Leesburg Pike) and
proceed past Route 123 (Chain Bridge Road).  Turn right onto
Westpark Drive (Gosnell Road in the other direction).  Turn right at the
next light onto Greensboro Drive and then right into the parking lot.
Visitor's Parking is adjacent to Westpark Drive.

A SIG representative will meet you in the lobby.
Please arrive no later than ten minutes to seven if you wish to join
us for breakfast, and no later than twenty after seven to attend
the meeting only.  The desk officer will ask for a driver's license
before issuing a visitor's badge.
