This unpublished article of Jerry Keiper's was the basis for the WRI Zeta poster of 1990. We present it here in memory of Jerry and as a tribute to him.

This package contains John Novak's updates to the Graphics`Graphics` package as of August 20, 2001.

A new, very fast code, SSFPQL, which solves the steady state quasi-linear kinetic equation describing the ion distribution function during ion cyclotron heating in two ...

This example shows how vector quantization, radial basis function, and feedforward networks compare when they are used to classify the data from a hybrid gas array sensor, an ...

n this paper, we construct a new mixed function method for the first time. By using this new method, we study the two nonlinear differential-difference equations named the ...

The possibility of construction of efficient databases in mechanics is illustrated by using the computer algebra system Mathematica. In the same system, it is also possible ...

The control.m package solves some basic control engineering problems: calculation of zeros and poles of transfer functions, plotting of Nyquist diagrams, Bode diagrams, root ...

In this paper, we present closed-form expressions for the correlation functions associated with Gaussian surfaces with certain ocean-like spectra. These correlation functions ...

Given a set A, the set of all possible relations defined on it has found a prominent place as a natural framework both in applied and theoretical research. A relation on A is ...
