Cellular::Automata::Wolfram is a Perl module that implements one-dimensional non-totalistic cellular automata as described in Dr. Steven Wolframs, A New Kind of Science, ISBN:1-57955-008-8 SYNOPSIS use Cellular::Automata::Wolfram; my $png_file = shift; my $caw = new...

The Wolfram Machine project is an effort to create a set of documentation and useful modules (both hardware and software) for a computing architecture based on the mathematical theories presented in Steven Wolfram's book _A_New_Kind_of_Science_.

This is a little script that uses Python to generate the cellular automata that Wolfram discusses in his book "A New Kind of Scilfram disquot;.The script uses the Python Imaging Library to render the output, but you could replace this with text or any other method of visualization.

The forced Duffing oscillator exhibits behavior ranging from limit cycles to chaos due to its nonlinear dynamics. When the periodic force that drives the system is large, chaotic behavior emerges and the phase space diagram is a strange attractor. In that case the behavior of the system is...

Flow past a wedge is governed by the Falkner-Skan equation. This equation admits only numerical solution, which requires the application of the shooting technique. The program plots the velocity for various wedge angles. The result obtained is in agreement with figure 8-10 in page 352 of Deen's...

In the programs, we perform flash calculations of a mixture of hydrocarbons (ethane, propane, n-butane and n-pentane) using the Rachford-Rice equation. The phi-phi method, based on the SRK equation of state, is used to compute the equilibrium constants. We also find the True Vapor Pressure. All...
