0205-388: 1993 Mathematica Days Information (July 30, 1993)
Author: Wolfram Research
Each Mathematica Day will give attendees a practical introduction
to Mathematica. If you are interested in getting started with
Mathematica, learning how it can benefit you at work, or seeing
how others are using the system, attend a Mathematica Day this
fall in Ann Arbor, Boston, Paris, London, or Frankfurt.

0205-377: BatchRead: An extension of Get to display and record the In & Out
(August 2, 1993)
Author: Robby Villegas
BatchRead is an extension of the Get (or <<) command for executing
the Mathematica commands in a batch file. In addition to
executing the inputs, it enters them into the kernel history of
input and output (the In and Out names) and displays the input and
output on the screen as it goes through the file. Thus, you see
the execution history of the file, and it is entered into the
session in the same way as if you had typed the commands in.

0205-412: Beam Statics Package (August 2, 1993)
Author: Levent Kitis
The package BeamStatics.m is intended as a sample program for
engineering students enrolled in a strength of materials course.
The package accepts as input: 1) concentrated loads; 2) constant
or linearly distributed loads; 3) boundary conditions; 4) flexural
rigidity; 5) length of the beam; and 6) rigid in-span support
locations. The output produced includes a picture of the beam and
the loads acting on it, as well as diagrams showing the
deflection, slope, bending moment, and shear force.

This package contains functions that convert a color expressed in
one of several color systems to an RGBColor. It also allows you to
find the appropriate RGBColor for a particular color name (such as
Blue).

0205-456: Context-Free Grammars (January 27, 1993)
Author: Charles Wells
The Mathematica notebook, ContextFreeGrammar.ma, contains a
command AcceptQ that takes a context free grammar and a string as
arguments and determines whether the string is generated by the
grammar. As a side effect it prints successively a list of
strings that derive to the given string in n steps. It stops and
accepts when it finds the start symbol in that list. If it comes
up with the empty list, it rejects.

0203-319: The Dirac Delta Function (July 15, 1993)
Author: Emily C. Martin
This package defines the function UnitStep and its generalized
derivative DiracDelta. It extends Limit, Integrate, and
Derivative to accept UnitStep and DiracDelta.The Dirac Delta
function is not a true function in the usual mathematical sense
since it is not defined for every value of x. However, it is
commonly used to represent ideal distributions in problems in
physics and engineering. The unit step function may be used to
represent piecewise continuous functions.

Exact and Inexact Numbers (July 15, 1993)
Authors: Stephen Wandzura
This package defines the functions ExactNumberQ and Realize.
ExactNumberQ[expr] returns True for rational numbers and
mathematical constants, and sums, products, and powers involving
only such numbers. Realize converts exact numbers, in expressions
involving both exact and inexact numbers, into inexact numbers.

0205-355: Extended Portable Bitmap Toolkit (December 10, 1991)
Author: Jeff Poskanzer
PBMPLUS is a toolkit for converting various image formats to and
from portable formats, and therefore to and from each other. The
idea is, if you want to convert among N image formats, you only
need 2*N conversion filters, instead of the N^2 you would need if
you wrote each one separately. In addition to the converters, the
package includes some simple tools for manipulating the portable
formats.

0205-546: Filter Design by Pole-Zero Placement (December 14, 1992)
Author: H. Joel Trussell
The program is designed to help the student "get a feel" for the
relationship between pole-zero placement and frequency response of
digital filters and systems. The user places poles and zeros
around the unit circle graphically using the mouse. The resulting
frequency response is displayed in absolute scale and in dB scale.
The phase response is shown.

0205-490: Generating the Koch Snowflake with Mathematica (September 15,
1992)
Author: Roman Maeder
The package KochSnowlfake.m defines a function to draw the Koch
snowflake. The Koch snowflake is constructed by starting with an
equilateral triangle, then adding to each side of that triangle
another equilateral triangle pointing outwards, centered on the
edges. The size of these new triangles is 1/3 the size of the
current edges.

0205-401: Geometry in Motion (August 1, 1993)
Author: George Beck
MapPoint is a geometry program which combines the traditional
geometric constructions of classical Euclidean geometry with the
more dynamic geometric transformations of modern geometry. Many
examples are given showing how to create, transform and animate
whole configurations of lines, circles or polygons in the plane
and in space. In fact anything that can be drawn can be
transformed.

0202-239: Interactive TeX/Mathematica Documents (February 1, 1993)
Author: Dan Dill
TeX/Mathematica is a set of tools that provide facilities of
Mathematica notebooks in a UNIX environment, under GNU Emacs.
They permit interaction between a text and a Mathematica buffer
and, if desired, the use of TeX/LaTeX to annotate
Mathematica-based explorations and programs. Inclusion of
Mathematica-generated graphics in TeX/LaTeX documents printed
using PostScript is supported. The tools also support the
automatic generation of Mathematica packages from Mathematica
documents.

0205-502: The Kaiser Window (December 1, 1992)
Author: Julius O. Smith III
This is a Mathematica notebook which investigates frequency-domain
properties of the Kaiser window. It is instructive to explore the
effect of changing the various parameters such as window length M,
FFT size NN, and the "alpha" parameter of the generalized Kaiser
window.
