Expression4J (Math Expression Parser) is a java framework used to manage mathematic expression stored in String object like "f(x,b)=2*x-cos(b)" or "g(x,y)=f(y,x)*-2". Expression gramar can be define by user (add new operator or type ...)

FM100 is a computer simulation of the Farnsworth-Munsel 100 hue colour (color) vision test. The results of the test can be used to assess the user's colour vision.

Fachwerk calculates strut-and-tie models used by structural engineers for analysing and designing reinforced concrete structures. The program only uses the equilibrium conditions, thus it is not assuming elastic behaviour.

DTMF detector library and/or application that reads in the specified audio file and returns/outputs whether DTMF detected and/or list of detected digits. May have GUI and command line interfaces.

FishLAB is an easy-to-use program for tracking aquarium water chemistry. With FishLab you can monitor pH, hardness, NH4, NO2, NO3, Fe, CO2 (the software converts units where needed). The graph function warns you of bad trends in water quality.

A open source, multiplatform, fractal generator and explorer. Includes Mandelbrot, Julia, Lambda and others popular formulas. Also includes formula reader to create new fractals. It can save PNG images. Requires Java Virtual Machine.

Fractal KISS means "keep fractals simple and sensible". The objective is to discover a "common-sense" understanding of fractals and their utility.

GCalc is mathematical graphing calculator system in Java

The GDL editor is multiplatform application that allows users to create, edit and run GDL files. GDL is a formal language designed to represent clinical knowledge for decision support. It is designed to be natural language- and reference terminology- agnostic by leveraging the designs of openEHR Reference Model and Archetype Model. The tool provides an editing and testing environment capable of generating forms based on the elements defined in the GDL. Requirements: Java Runtime Enviroment (JRE) 1.6 or higher

Gene Ontology Browsing Utility (hereinafter, GOBU, pronounced as "go-boo") is a browsing and manipulating tool for Post-Pipeline genetic data, especially useful for data with GO annotations. With help of GOBU, we expect biologists and their cooperating technicians can pay less effort on common programming stuff. At the same time, GOBU provides an Extendable Architecture which guarantees the possibility of 1. Arbitrary Data Description, 2. Data Integration, and 3. Extendable User Interface.

GPSylon is a Java moving map application that is able to display maps like in an atlas and show your position by the use of a gps device. It may track your path, load overlays (e.g. shape files), download maps from expedia servers. - The source code was moved to github!

GeoDress is a program for reverse geocoding of JPEG pictures with a simple GUI and even a command-line interface.

NOTE: this project has been renamed as GeoGig. Use this URL to get to the GeoGig downloads: https://sourceforge.net/p/geogig Welcome to the GeoGit project, exploring the use of distributed management of spatial data. GeoGit draws inspiration from Git, but adapts its core concepts to handle versioning of geospatial data. Users are able to import raw geospatial data (currently from Shapefiles, PostGIS or SpatiaLite) in to a repository where every change to the data is tracked. These changes can be viewed in a history, reverted to older versions, branched in to sandboxed areas, merged back in, and pushed to remote repositories.

[EN] GraficoAR is a lightweight, pure Java application for 2D mathematical function plotting and real-time analysis. Built with Swing without heavy external libraries, it features a custom recursive parsing engine that respects operator precedence (+,-,*,/). Features: dynamic Cartesian graphing, adaptive grid zooming/labeling, numerical differentiation (plots the 1st derivative in blue), and definite integration (Riemann sums with text output and transparent blue geometric shading under the curve). Includes angle unit toggle (Rad/Deg) and a portable stand-alone version with bundled JRE. [IT] GraficoAR è un'app Java leggera per lo studio e il tracciamento di funzioni matematiche 2D. Sviluppata in Swing senza librerie esterne, usa un motore di parsing ricorsivo (+,-,*,/). Offre: grafici cartesiani dinamici, zoom con etichette assi adattive, calcolo della derivata (linea blu) e dell'integrale definito Supporta Gradi/Radianti.

Le projet Gramlab vise à mettre à disposition des entreprises des outils logiciels OpenSource et gratuits, qui peuvent être mis en oeuvre par des développeurs qui ne sont pas spécialistes du traitement des langues. Note : L'outil GLabCorpus Manager nécessite l'installation d'un serveur SolR. Pour le télécharger et plus d'information, veuillez vous rendre dans la section Files.

Graph-RAT is a database abstraction layer designed to make it easy to use a large library of graph-analysis routines on a database as well as add new kinds of algorithms to data mining.

Gridder is a group of portlets that simplify the use and administration of grid services. Especially for job submission management. Gridder also extends and documents the functionality of the OGCE Bundle. It is plenty of useful documentation.

HELEN is a flexible framework to support the computer-based management of Clinical Practice Guidelines (CPG). It covers the whole life-cycle of a guideline, providing methods and tools for each step (from development to clinical use).

Virtual instrumentation software, currently designed for modifying automobile engines. Intended as a modular framework to communicate with devices on an IO port (serial, parallel etc.) and allow a visual representation of the instrument.
