xrayutilities is a python package used to analyze x-ray diffraction data. It can support with performing diffraction experiments and used for common steps in the data analysis. It can read experimental data from several data formats (spec, edf, xrdml, ...); convert them to reciprocal space for arbitrary goniometer geometries and different detector systems (point, linear as well as area detectors); for further processing the data can be gridded (transformed to a regular grid). More detailed description as well as documentation can be found at webpage http://xrayutilities.sourceforge.io/. Downloads for windows can be found on http://pypi.python.org/pypi/xrayutilities Development is performed on github: https://github.com/dkriegner/xrayutilities

Welcome to the home of homemade lasers and to the braniac laboratory. This site is devoted to the homemade lasers. And guides where it is described how to build them step by step. Any laser described in the guides can be build from scratch using only the common accessible resources. You won't need rare crystals, optics, mirrors or anything like this. On the other hand all lasers here are the demo of the concept. (Rather) cheap, quick-and-dirty mockups. Feel free to make for them proper housing and shining handles. My task is simple - to show that lasers ARE simple. Not less not more.

ART is a flexible simulation framework for wind instruments. It includes a growing library of modelling elements. So far bore discontinuities, branches, tone holes, cylindrical and conical tubes, Bessel horns and bent tubes are available for frequency domain modelling. In the time domain generic bidirectional propagation elements, scattering elements, fractional delays, convolution with reflection functions and general z-domain networks are available and can be described using MuParserX expressions. Cylindrical and conical ducts can also be defined based on their geometry. Available models and their parameters can be enumerated and combined to form simulators for complex acoustical structures. Parameters can be specified symbolically by expressions containing other parameter values or global variables. Dependencies between parameters are resolved at run time. However, MuParserX expressions are compiled at design time. Zero-delay loops are detected and reported.

The Library is for Finite Transforms such as the Number Theoretic Transform (NTT) and Finite Radon Transform (FRT). Current modules include NTTW for NTTs with high resolution (microsecond) timing, basic array and imaging. The transforms are optimised for performance.

A self-sufficient java framework for numerical solution of ODEs (diff eqs) and visualization. Samples are aeronautics/astronautics/physics/rocketry themed. Focus on clean design, modularity, reusability and documentation. Educational project.

Integration routine to be employed in evaluation of high dimensional integrals arising from problems in statistical mechanics, more specifically the partition function of classical Heisenberg spin-chains, and its resulting derivatives.

QNANWidgets is a collection of science/engineering oriented Qt Widgets to help in creating sci/eng. applications and include a chart and plot widget. The widgets are easy to use and can be customized in Qt Designer directly.

QuantimSim is a physics simulation engine. Some aspects of astrophysics, electromagnetism, relativity, thermodynamics, statistical mechanics and quantum mechanics will be included in the simulation library.

Visible emission spectra processing utility.

BS Eagle Project is an open source black-oil simulator. The goal of this project is to provide a free access to the modern oil simulator to study new methods of simulation. The project has a modular architecture and open to modifications and extensions.

A MatLab toolbox with many simple and useful functions for analyzing data from Cluster, Champ and the future Swarm missions. Other functions for space science, magnetospheric and ionospheric research are included. The toolbox is designed to be as simple as possible. Each function can be learned and used individually.
