DiffEqs is a collection of fast, robust, and thoroughly tested packages for differential equations. The primary package in DiffEqs is DEGraphics, which provides the ...

The flow of the Riemann zeta function, _ s = (s), is considered, and phase portraits are presented. Attention is given to the characterization of the flow lines in the ...

Perturbations and eikonal instabilities of black holes and branes in the Einstein- Gauss-Bonnet theory and its Lovelock generalization were considered in the literature for ...

This package calculates the compositions of coexisting thermodynamic phases in binary mixtures, using the method of double tangent construction. In addition, the package ...

DynPac is a comprehensive package for solving (numerically) and plotting the solutions of sets of ordinary differential equations. The plotting routines include time plots, ...

Mathematica notebooks for classroom demonstrations or individual student use in Differential Equations. Included are a few additional Mathematica palettes. Topics: Animated ...

The simple pendulum problem in mechanics can be solved using the Sn Jacobi Elliptic function. In this notebook we make some nice plots of the phase space of the system using ...

A Packege called SmoothPhase.m is provided and demonstrated in the notebook SmoothPhase.nb. The package defines a function by the same name. To understand what the package ...

Conventional analog phase shifter designs use quadrature hybrids with two identical varactor diode networks to provide a continuously variable phase shift with voltage. These ...

The purpose of the project described here is to provide a graphic demonstration of the role of phases and amplitudes in determining the appearance of printed characters. The ...
