Suite of tools for drawing graphs about social indicators of progress and Web2.0 site for discussing about them. Please, visit the Trac page on SourceForge at http://apps.sourceforge.net/trac/mindgapper/

A BigInteger binding for Node.js (http://nodejs.org/) using GMP (http://gmplib.org/).

OMG is an online 2-D Mesh Generator. Using Shewchuka Triangle (written in C) to generate DT and a Quadtree algorithm (written in php) to triangulate a PSLG. A few Import end Export functions are included. Using SVG to display meshes.

Large Integer Calculator. Includes most arithmetic functions plus named memory values.

That project aims at delivering a reference implementation of a library, estimating and serving average prices paid for air travel products. It is not intended for use by an actual airline, but rather by simulators or other airline-related modules of

Code, Data and more for cooperating Open Climate Science web initiatives.

The Open Optimization for Java provides a framework and the implementation of commonly-used algorithms found in Graph Theory and Network Optimization, e.g. shortest path and postman problem.

This are utils used for solving differents things in math.

A Javascript collection with over 400 mathematical functions including but not limited to: extended statistical functions, geometry, matrix calculation and a lot more. A simple frontend including a virtual keyboard is also in this packet.

:: Pythia :: This is a high quality fast "true random" number generator / shuffling system. This means that Pythia never ever repeats the same numbers again regardless of how many tests you do. This also means that it never generates any numbers in a predictable order no matter how many times you refresh. Pythia solves a great problem and is by far the best solution out there. How to use: var my_pythia = new pythia(); Pythia API: .generate - Generate a new random number. .reset - Reset and enable to restart and -probably- regenerate same numbers. Enjoy!

Based on MinimPy (http://sourceforge.net/projects/minimpy/), QMinim is a web-based minimization application, for allocation of subject to different arms of a clinical trial. It is an alternative to randomization, with the advantage of balancing arms of trial with respect to preselected prognostic factors. All aspects of minimization procedure including treatments, factors, minimization protocole, and including a preload can be customized using QMinim.

Just a basic 4 band resistor color calculator with chart.

The SWire Web App Collection (SWAC) is a collection of demo web applications which explain how to use SWire and SWire4js in developing SWire web applications, namely, software which runs on web browsers and interacts with Stata. SWAC is an open source project and you can download the code from the project web site web site or try the apps on-line here: http://swire-web-apps-collection.sourceforge.net/

SWordy is an Office add-in which allows data import from Stata into a Microsoft Word document. SWordy can also create automatic documents, namely Word documents which can automatically update their data by retrieving it from Stata.

That project aims at studying and comparing typical airline IT methods, for instance RM-related algorithms. It works from a Unix/Linux/Mac command-line, and exposes basic APIs. It is being developed in C++, with Python wrappers for some components.

That project aims at studying the impact of IT systems interactions on traveller demand and airline revenues. Passenger demand is generated (Monte Carlo) and injected into simulated CRS and airline IT systems. Differential analysis is then performed on various changes compared to a bottom line scenario.

An online unit converter.

VisualIntFactor will be an interactive educational and scientific tool demonstrating multiply, factor, conversion between unary counting and binary integers, all in the same grid of hexagons. This grid is based on pascals triangle, which is a 1d cellular automata that calculates (X choose Y) factorials by each cell being the sum of the 2 cells upleft and upright. Draw a binary integer from a cell going upright, then explore the allowed transforms which may lead you to a factored state in 2 dimensions, from the lowest digit of the 2 odd integers both upright and upleft, its factors, and in the 2d space they are rectangle edges of, those pixels/digitbits must be on when there is an on bit somewhere downleft and downright after crossing empty cells, but if it finds either whole diagonal row empty then it must also be empty/zerodigit. The 2 main rules are: Any 2 cells below may both turn off and turn on the one above, or the reverse, and any on cell may move horizontally to an empty cell.

Yagy is a (yet another) Graphical user interface for Yacas, a (yet another) Computer Algebra System. NOTE: Yacas and yagy development has moved to github. The new repositories are located at https://github.com/grzegorzmazur/yacas and https://github.com/grzegorzmazur/yagy . The mailing list has been moved over to https://groups.google.com/forum/#!forum/yacas . The downloads section at sourceforge will be kept up to date for the foreseable future.

Are you always tired of searching the Windows calculator from some weird location from you PC? Zinuc is a web only, very simple, but powerful calculator. You don't have to download anything to use it. Check out the web pages to find out more.

bignumber.js is a JavaScript library for arbitrary-precision decimal and non-decimal arithmetic. Faster, smaller, and perhaps easier to use than JavaScript versions of Java's BigDecimal. Replicates the toExponential, toFixed, toPrecision and toString methods of JavaScript's Number type. Includes a toFraction and a correctly-rounded squareRoot method. Supports cryptographically secure pseudo-random number generation. Wide platform compatibility, uses JavaScript 1.5 (ECMAScript 3) features only. If a smaller and simpler library is required see big.js. It's less than half the size but only works with decimal numbers and only has half the methods. It also has fewer configuration options than this library, and does not allow NaN or Infinity. See also decimal.js, which among other things adds support for non-integer powers, and performs all operations to a specified number of significant digits.

2020: MOVED TO https://github.com/peterjtracey/desqchess -- because it's 2020... Version 3 fork of desqchess. DESQChess will be an easy to use, easy to add on to, easy to animate chess system. Useful for apps, tablets apps, and desktop systems. Plans for other plugins include: - Add plugin to connect to animation system (web GL) - Connect to other open-source software such as Blender, illustrator, GIMP, and Vector graphic manipulation programs.
