For many situations in Quantum Information Theory it is necessary to trace out a subgroup of qubits from a larger group. For example, suppose Alice, Bob and Charlie each have ...

A system of two catalyst filled packed bed reactors is to be designed using the method of maximization of rectangles, the optimum conversion versus temperature data and the ...

In this case study we demonstrate, how to employ the Mathematica CSPS application together with the OPTDesign package developed by Helton and Merino (1998) to design a robust ...

Three equilibrium reactions are taking place simultaneously to produce SynGas using coal and steam. We start by plotting the equilibrium constant versus temperature assuming ...

When activation energy is high enough, a nonisothermal CSRT, where a first order reaction is taking place, exhibits multiple steady states. In the notebook, we show how ...

This notebook arose from research on the statistical geometry of stochastic fibre networks. Quite a lot of theory exists for the purely random case, based on a Poisson ...

FeynArts is a Mathematica package for the generation and visualization of Feynman diagrams and amplitudes. The current version 3 features a completely new rendering engine ...

The file gw2tide.zip includes two Mathematica notebooks. gw2tidal_fluctuation.nb covers groundwater response to tidal fluctuation in a leaky confined aquifer using Jiao & ...

Solving nonlinear systems, especially algebraic polynomial systems, is a fundamental problem which occurs frequently in various models of science and engineering like ...

The fourth dimension is an intriguing space, home of complex figures literally beyond the imagination. Although it is impossible to `see' even the simplest of these objects ...
