A tool for people interested in Special Relativity. Can introduce you to some basics, as the transformations and the 4-vectors. Examples, illustrations and some exercises will be included. With some time, effort, and space on the desk, you can master it.

Calculation of camshafts - allows to define a camshaft profile on the set trajectory which should provide the given mechanism. The trajectory can be set graphically, co-ordinates or function.

Adaptive Work-Centered User Interface Technology (ACUITy) utilizes semantic technology in an ontology-based approach to modeling and implementing intelligent user interfaces.

it provides a user interface to the economic theory through an intuitive and easily understandable quantification of the economic value of alternative business models.

The Bidirectional Object-oriented Transformation Language (BOTL) is a tool for object-oriented model transformations.

It's a Cat and Dog game,we develop the Inner AI strategy for the Dog and we also code the strategy of the cat in order to simulate the user. Furthermore we use Artificial Neural Network to build the experiment

The Genomic Diversity and Phenotype Data Model (GDPDM) captures molecular and phenotypic diversity data. MySQL databases are used to implement the schema. This project develops software tools (written in Java, Perl, etc.) associated with this model.

GSH builder is a free Galois Sub-Hierarchy visualization tool. The algorithm for calculating GSH is called Pluton and the present Java realization is based on two articles. "Efficiently computing a linear extension of the sub-hierarchy of a Concept Lattice" by Anne Berry, Marianne Huchard, Ross M. McConnell, Alain Sigayret and Jeremy P. Spinrad. "Performances of Galois Sub-hierarchy-building algorithms" by Gabriela Arevalo, Anne Berry, Marianne Huchard, Guillaume Perrot and Alain Sigayret In you're in need of other GSH algorithms or their realizations in C++, you might want to investigate a project called Galicia on sourceforge. This program is free software and is licensed under GNU General Public License as published by the Free Software Foundation. Only jre7 compliant at the moment.

GridABM is an easy-to-use toolkit to develop high-performance agent-based models (ABMs) in Repast. GridABM facilitates large-scale simulation of ABM on multicore computers, local computing clusters, or computational grids.

JAGAL provides implementations for directed graphs (weighted and unweighted) and varoius types of transition systems as well as utils for graph traversal and modification. JAGAL builds upon the Java library TOVAL (located at http://sourceforge.net/p/toval). To use JAGAL, make sure the TOVAL library is on the build path. This library uses and encloses jGraphX (https://github.com/jgraph/jgraphx). A documentation for JAGAL can be found under http://doku.telematik.uni-freiburg.de/jagal.

Japrosim is a java library for both discrete event and continuous simulation. GUI for modeling and automatic code generation are offered. An explanation module is integrated. Models are described in XML and owl for interoperability.

JAS-mine is a Java platform that aims at providing a unique simulation tool for discrete-event simulations, including agent-based and microsimulation models. With the aim to develop large-scale, data-driven models, the main architectural choice of JAS-mine is to use whenever possible standard, open-source tools already available in the software development community. It has built-in utilities for communicating with an underlying relational database. In addition, the platform provides standard tools which are frequently used both in agent-based modelling and dynamic microsimulations, like design of experiments (DOE), run-time monitoring and visualization with plots and graphs (GUI), I/O communication and statistical analysis. JAS-mine source code can be found on GitHub, with the core repository at: https://github.com/jasmineRepo/JAS-mine-core and the GUI repository at: https://github.com/jasmineRepo/JAS-mine-gui

JPowerFlow - a steady state electric power system power flow solver.

The Java Aspect Metamodel Interpreter (JAMI) is a research framework for modeling and experimenting with aspect-oriented programming languages. Common language design concepts and their operational semantics are modeled, and can be run by an interpre

Java Fuzzy Editor is a basic editor to allow creation of fuzzy based rules. It will save to serveral formats including to source code in several languages.

KEManager models Knowledge Based Systems following a methodological approach ( Knowledge Engineering) for academical purposes of CommonKADS and IDEAL. It supports the viability test, some knowledge acquisition techniques and conceptual modeling.

The Language for Executable Models (LEM) is a text-based representation for Executable/Translatable UML models. This project also includes a "verifier" for executing these models.

Metaquokka is a highly configurable xml editor, currently available as Gridsphere portlet. Besides the default format, there is suppoert for ESysXML, a simulation description scheme for a geodynamics framework. Supports Generic Mapping Tools rudimentary.
