Iterate is an implementation of the Bravais-lattice-finding algorithm from: Andrews and Bernstein, Acta Cryst. (1988). A44, 1009-1018 Lattices and Reduced Cells as Points in 6-Space and Selection of Bravais Lattice Type by Projections.

A C library for digital signal filtering

Lottie Vectors is an application for Matlab that alows you to do some pretty neat things -with vectors. More exactly -displaying them in ways that hopefully will allow you to explore and better understand your vector data. The basic idea is simple, take a vector defined in one of a few different types of data formats and map it on the screen. Add another vector and you start to form a 'route'. Each route or position vector can be accompanied with a 'force' vector. This can be used to show something acting on a position with direction and magnitude. Finally you can give each position a tag to display on screen. This could be a common math symbol or greek letter, start/end signposts, or a number of the position either from the begining or after a reset. After all the information has been loaded for your dataset. Either passed over the command line, or as a text file. Lottie Vectors displays inside a figure that you can resize, rotate and turn 2D positions into a 3D picture.

nPlot (alias nanoplot) aims to be a minimalistic, easy-to-use data analysis application.

PAScual is a data analysis suite for Positron Annihilation Lifetime Spectroscopy (PALS).

An automatic 2D Delaunay mesh generator and solver for Finite Element Analysis. Can solve 2D field problems (Poisson and Helmholtz Equations). Can use LAPACK/ARPACK solvers producing OpenGL/Postscript output. Uses C/GTK/GTKGLExt/MFC. Runs on Win32/Unix.

The pySpec project is a set of data analysis routines written in python for analysis of x-ray diffraction data produced by the SPEC X-Ray Diffraction and Data Acquisition software. This repo has moved to : https://github.com/stuwilkins/pyspec

QSE is an application intended to help in the initial stages of data reduction of EXAFS data taken with multi-element detectors using the 'Spec' data acquisition system.

Schur is a standalone program for interactively calculating properties of Lie groups and symmetric functions. Schur has been designed to answer questions of relevance to a wide range of problems of interest to chemists, mathematicians, computer scientists,...

Tkaero is a simple compressible aerodynamic calculator developed in Tcl/Tk.

trafo is a console-based "E-I" transformer calculator. It allows you to easily calculate all the necessary information to build an "E-I" transformer by only providing a few input parameters. This programs is for all of those who don't want to spend more time calculating transformers manually amd would like some automation.

Wavefront is a programme for simulating 2D acoustic systems, with a particular emphasis on determining wavefront shapes at the mouths of horns. It accepts CAD drawings in DXF format and produces animated displays of wave propagation as well as exporting various data as text files. It is GPL software and runns on Linux and Windows.

Axiom is a computer algebra system. It consists of an interpreter, a compiler and a library of algorithms. Axiom is an excellent research platform as well as a useful tool for scientific programming.

A curling game, It is written in Delphi. Release: 4th April.

Supports flow Simulation for Physics and Meso-Compartimental Simulations for Biological Systems. Uses a Container-Flow based System.

Library of functions used to model simple (one dimensional) liquid crystal cells

A 2-D inviscid flow and adjoint solver on unstructured triangular grids. It makes use of a vertex-centroid finite volume scheme which is second order accurate. The adjoint solver is developed using the automatic differentiation tool called TAPENADE. Code has been moved to https://github.com/cpraveen/euler2d

This is an extension to the standard 2D HF package (A Numerical Hartree-Fock Program for Diatomic Molecules by Jacek Kobus, Leif Laaksonen and Dage Sundholm) that adds some extra functionality.

Simulate 2D physics with my engine entirely made in JavaScript. Modify live existing scenarii or create your own from scratch with the live editor. Try it on the demo web site! :) Note : If you intend to download and use the sources as it is, you need to host it as scenario resquests are made in AJAX.

2DFLT it is first out of two programs which allows implementation of Phase Sensitive Detection (PSD) and/or Modulated Enhanced Diffraction (MED) techniques on the in situ data. This software allows collecting individual data files from in situ experiment into one dataset. After that this data set can be visualized, edited, normalized and averaged. Resulted data can be saved as one flat file (FLT-format) which can be used for PSD/MED calculations via 2DMED software (http://sourceforge.net/projects/twodmed/?source=directory). 2DFLT specifically was written to target in situ X-ray Powder Diffraction data from synchrotron measurements. Hence it can read CHI, XYE (TOPAS), FXYE(GSAS/ GSASII) and XY- files formats. However it can read general in situ data written into individual TXT or XY – files.

2DMED it is the second out of two programs which allows implementation of Phase Sensitive Detection (PSD) and/or Modulated Enhanced Diffraction (MED) techniques on the in situ data. This software takes normalized and averaged in situ data in flat file format (FLT) and performs PSD transformation which has been described in Urakawa, A.et al. Chem. Eng. Science 2008, 63, 4902. User can choose demodulation index k and perform several demodulation calculations. This is extremely important since demodulation calculations at k = 2 on in situ powder diffraction data represent implementation of MED method which been described in Chernyshov, D. et al. Acta Cryst. 2011, A67, 327. Demodulated data can be then viewed on 2D and/or 1D plot and analyses with different tools including In Phase Plot, Maximum Amplitude Plot and Positive Pattern Plot. Demodulated data also can be saved in ASCII format for further analysis.
