PyPhys is a set of physical quantity classes written in Python. The classes represent physical quantities (like length, pressure, energy, etc.) that can be assigned and extracted in many different units.
Remember when you wrote your games in Pascal? Well continue that fine tradition by using JEDI-SDL! Which works with Delphi, Kylix, Free Pascal, Gnu Pascal and TMT Pascal. Cross-platform game develpment has never been easier!
Simulation of diffraction pattern duality experiment. Each particle impacts the phosphor screen at a particular localized point, but when many individual particle impacts occur, the wave-based diffraction pattern emerges.
PIMC++ is a code designed to perform fully-correlated simulations of quantum systems in continuous space at finite temperature using Path Integral Monte Carlo.
It is designed in a modular way to facilitate easy addition of new algorithms.
MOVED: http://code.google.com/p/rssfilter/ Selects and/or rejects articles from RSS feeds based on keywords you supply. Runs in your taskbar! Originally intended to filter new content from scientific journals such as PRL or the arxiv (cond-mat, etc)
This project is a collection of FreeFEM++ scripts used to find numerical solutions
of the free-surface incompressible Navier-Stokes equations. The boundary interpolations from a moving mesh are suitable for applying surface tension boundary conditions
SonicData is a data collection and analysis program used in connection with a sound card voltage-to-frequency interface. Its intended use is for laboratory instrumentation.
Diofantos is a library for the solution of equations that arise in physics. It deals with ordinary differential equations (ODE), partial differential equations (PDE), including grid generation, and integral equations.
This program simulates the performance of the supersonic continuous wave chemical laser by solving 2D-system of Navier-Stokes equations in slender-jet approximation that includes multi-component diffusion, non-equilibrium chemical reactions and radiation
Ordinary Differential Equation (ODE) solver for Tcl. Handles both stiff and non-stiff sets of equations; does time-evolved initial value problems and root finding. Based on the popular Lawrence Livermore solver LSODE.
Thermocouple Scripts. Thermocouples generate a voltage at a given temperature. The relationship isn't simple. There are published tables, but the format can be awkward. This project supplies tools to find, parse, plot, and curve-fit thermocouple data.
Step is an interactive physical simulation program for education. StepCore is a physical simulation library on which Step is based. Please refer to http://edu.kde.org/step for more details.
GVIB is a user friendly package for vibrational analysis. Given a molecular geometry, it will calculate vibrational frequencies and intensities using anharmonic internuclear potential.
Mito-MAS-m is a simulator of the mitochondrial inner membrane and the enzymatic complexes embedded in it, implementing a coarse-grained (CG) model of the molecules using rigid structures and Dissipative Particules Dynamics (DPD) as motion equation.
Matho is a OS Independant Application and API for mathematical operations, features include curve sketching, calculus, iterative formulae, algebra solver, 2d/3d geometry and mechanical and statistical functionality.
OpenDiscreteDynamicProgrammingTemplate : founds optimal constrainted parameters of a discrete controls with second order optimization template replacing Hessian with directional derivatives and backpropagation for digital filter(as neural network)
FSEM is a set of freeFEM++ scripts and C++ code to solve the drift-diffusion (DD) semiconductor device equations by the finite element method (FEM). It was initially developed for the nonlinear study of semiconductors under high optical injection.
