Attention:
To Members and Friends of DC SIGAda Next Meeting:
Our Next Meeting is scheduled for Tuesday, 8 February 2005, as a Joint Meeting of the
Baltimore and DC SIGAda Chapters. Stephen Leake will be speaking on "Stephe's Ada Library; 15 years of Useful Ada Packages".
The meeting will be held in the cafeteria of the
Johns Hopkins University/Applied Physics Laboratory near Laurel, Maryland
Munchies and soft drinks will be served at 7:00 PM, the general
meeting will start at 7:30 PM, and the program will follow
shortly afterwards.
Abstract: Stephe's Ada Library; 15 years of Useful Ada Packages
SAL is a collection of stuff I've found useful in my projects A large
part of SAL provides a coherent set of generic abstract data types,
intended to be yet another entry in the "Standard Ada
Library" discussion. My goal in this part of SAL was to provide
Ada packages that take full advantage of the flexibility and power of
Ada generics, while at the same time making things relatively easy for
the casual user. Another large part of SAL provides math operations
for kinematics and dynamics of masses in 3 dimensional space.
Cartesian vectors, quaternions, orthonormal rotation matrices, moments
of inertia, forces, acceleration, velocity are supported, in 3 and 6
degrees of freedom (translation and rotation).
Presenter: Stephen Leake
Stephen Leake graduated from Rensselaer Polytechnic Institute in 1980
with a Bachelor's in Physics, and got a Masters in Physics from
University of Maryland at College Park in 1982. He worked in robotics
at NIST (then NBS) until 1990, when he moved to NASA Goddard Space
Flight Center, working on the space station robot program. That was
his first experience with Ada, and he has been hooked ever since.
Recently he has been building satellite simulators for Goddard, used
in testing flight software and hardware.
Directions From Washington, DC
From the Capital Beltway (I-495),
1. Take the I-95 North exit;
2. Exit onto MD Route 32 West, at the Columbia exit (~ 10 miles);
3. Exit to go South (left) on U.S. Route 29; (~ 2.5 miles)
4. Right onto Johns Hopkins Rd at light to go WEST
(There is now a new style overpass/interchange
with a traffic circle on the East side of US RT.29
which replaced the traffic light at this intersection.
-- Those traveling North on 29 from Silver Spring
will take the exit for Gorman Road & Johns Hopkins
Road to reach the traffic circle, then go 270 degrees
around the circle to make a logical Left turn to
go WEST on Johns Hopkins Road.)
5. Turn Right onto APL Road (first right past the lake)
6. Use Building 1 Visitor Parking;
7. Use Building 1 entrance near the flag-pole; The meeting is in the cafeteria.
