SONNET
SONNET (integer) linear optimisation in .NET
SONNET builds on top of the well-known COIN libraries for optimisation (see http://www.coin-or.org). It brings the power of (integer) linear programming projects of COIN to .NET. SONNET is licensed under the terms of the Eclipse Public License (EPL). SONNET consists of two parts: 1) A .NET library that consists of .NET wrapper classes around existing COIN classes such as OsiSolverInterface. 2) A .NET library implemented in C# that adds a powerful (rudimentary) modelling API with classes like Model, Constraint, Variable, Expression, etc, and overloaded operators to allow for things like Model model = new Model(); Variable x = new Variable(); Variable y = new Variable(); model.Add(2 * x + 3 * y <= 10); model.Objective = 3 * x + y; Solver solver = new Solver(model, typeof(OsiClpSolverInterface)); solver.Maximize(); Console.WriteLine(solver.ToSolutionString()); -

AwesomeBump
Open Source graphic tool and alternative to Insane Bump
AwesomeBump is a free and open source graphic app written using Qt library. It was made as an alternative to known gimp plugin Insane Bump or the commercial tool Crazy Bump. It is designed to generate normal, height, specular or ambient occlusion, metallic, roughness and other textures from a single image. Most of the image processing is done on GPU so the program runs very fast and all the parameters can be changed in real time. -

Win-Brash
A Windows Native Bourne Shell Interpreter
Win-Brash is a recoding, from scratch, of the Bourne shell as a native Microsoft Windows multi-threaded command line application. It uses Bourne shell syntax but recognizes Windows file names. The TAB key helps convert Unix style pathnames to fully valid windows pathnames. It also adds missing backslashes -- to reduce the need to always type two. For Documentation see: http://www.bordoon.com/brash To give brash.exe a try, use the download link to get winbrash-1.2.16.zip. Unzip... -

CQU
Decision solver for Counting Quantifiers over Unary Predicates
...It also emplouys COIN-OR Clp linear programming solver, and inherit from it. Given a CQUSAT instance in normal form as input, the program returns a solution, if there is one. The implemented method employs dual Simplex Algorithm with Column Generation. At each iteration, a SAT instance is generated and a SAT Solver (minisat) decides its satisfiability. Details about CQUSAT, its normal form and this turing reduction can be found in the paper "CQUSAT.pdf" that comes with this package. ... -

RAtom
solves nonlinear Kohn-Sham equation for the neutral atom.
...High order Gauss quadratures are applied in order to obtain the total energy of atom with absolut accuracy of 1E-6 hartree. Disctretization leads to generalized eigenvalue problem, which is solved by procedures from LAPACK libraries. The program is implemented in C++, it runs as a single thread. The implemented algorithm is described in the following papers: 1. Z. Romanowski, "Adaptive solver of a Kohn-Sham equation for an atom", Modelling Simul. Mater. Sci. Eng. vol. 17, 045001 (2009) 2. Z.

TrackingExample
This project presents simple marker detection and 3D augmentation
This is a project demonstrating tracking of a marker consisting of 6 blobs placed on a black palette and drawing a virtual house on it. Detection of the marker and augmentation (drawing of the house) are done in real time. Image from almost any internet camera can be used. The program is using incremental tracking, in which the position of the marker in the previous frame is used to improve the detection. The homography calculation needed for the augmentation can be performed using 4 different methods: -Direct Linear Transform, -basic OpenCV algorithm -OpenCV RANSAC based algorithm -OpenCV Least-Median based algorithm. ... -

tabipb
A treecode-accelerated boundary integral Poisson-Boltzmann solver
TABI (treecode-accelerated boundary integral) solves the linear Poisson-Boltzmann equation. The solver employs a well-conditioned boundary integral formulation for the electrostatic potential and its normal derivative on the molecular surface, which is triangulated and the integral equations are discretized by centroid collocation. The linear system is solved by GMRES iteration and the matrix-vector product is carried out by a Cartesian terraced which reduces the cost from O(N^2) to O(N*logN), where N is the number elements. ... -
