JSwarn is a particle swarm optimization (PSO) package written in Java. Designed to require minimum effort to use (out of the box) while also highly modular.

Currently, all existing formal tools are designed to serve as formal verifiers, using one implementation or another. JTLV is a new tool aimed to facilitate and provide a unified framework to the development of formal verification algorithms.

An open source Java based library for target tracking algorithms as well as evaluation tools. Currently contains 11 different sequential filters, such as; Kalman, particle, H infinity, interacting multiple model (IMM), and others.

JTextPro: A Java-based Text Processing tool that includes sentence boundary detection (using maximum entropy classifier), word tokenization (following Penn conventions), part-of-speech tagging (using CRFTagger), and phrase chunking (using CRFChunker).

A rather simple java program for parsing plain text files (generally in large numbers), which should then offer frequency statistics of usage, graphs, full-text search and maybe something more.

JTHERGAS (a JAVA implementation of THERGAS) estimates thermodynamic information from two dimensional graphical representations of molecules and radicals based on the Benson additivity method.

Road traffic simulator/game with lots of vehicules, different drivers characteristics, accidents, detours, manual or script-driven traffic lights control, pedestrian traffic, road-works, and plenty more! Solve your simulated traffic-jams problems!

The JUMP DB Query Plugin is an extension for the OpenJUMP GIS platform that allows OpenJUMP users to give arbitrary database queries to retrieve and display geographic feature sets. Spatial databases currently supported are PostGIS, Oracle Spatial, MySQL, and SpatiaLite.

Java-based extensible high-precision math package. Includes support for computations based on fractions. Support is included for converting to floating point numbers and BigDecimals.

JUndo is a declarative object-oriented programming language with functional, and intensional programming characteristics. Applications include multi-level undo and sophisticated error recovery. See http://verdantium.blogspot.com/

Runtime library for the JUndo language. See http://verdantium.blogspot.com/

This tool pulls all JUnit testcases from the class path and run them all. After completion of test case execution it populates the result in database tables. A report tool fetch the result data from database and produce an HTML report. Highlights of this tool - No coding effort is required from developer to integrate existing JUnit test cases. They just need to put their test case folder to the class path - Since it keep the test result data in a database, it can keep history of any number of past execution result. This build is bundled with open source embedded database HSQLDB. User may also use other database or their choice - The HTML report can also include previous run results. Number of last run result to include in report is user configurable - Flexible and de-coupled design

Simple VA18B multimeter interface. It reads data trasmitted by USB/Serial interface of VA18B multimeter and can put them into a CSV file.

JVClifford is composed of Java/Java3D packages and executables jars that provide for Clifford element definition, Geometric Algebra operations and geometric scenes modelling and rendering using the n-dimensional geometric algebra affine model

jversim is a traffic simulator. Simulated networks can have one- or two way roads, destinations and simple crossroads. It shows a graphical simulation and problematic areas. It can be used as a toy or for learning about discrete simulations.

Java Visualisation Tool

JVisu applet and browser based HMI visualization for PLC's and process automation. Flexible design, easy extensibility and platform independecy is the goal.

JVisual3D is a GUI library, 3D geometry viewer and a mathematical visualization software written in pure java. It is comparable with the well known javaview project. This is under GPL. Create, manipulate and display easiely meshes, 3d shapes, surfaces,..

JVnSegmenter is a Java-based and open-source Vietnamese word segmentation tool. The segmentation model was trained on about 8,000 sentences using Conditional Random Fields (FlexCRFs). This tool would be useful for Vietnamese NLP community.

JWebPro: A Java tool that can interact with Google search and then process the returned Web documents in a couple of ways. The outputs can serve as inputs for NLP, IR, infor extraction, Web mining, online social network extraction/analysis applications.

JWhirli is a graphical simulator that allows one to model whirligig beetles.

Java visual aplication to show graphs. JWykres get data from dabases by jdbc. Aplication can show many dataset on one graph for easy comparison, for example to find interrelation beetwen processes or finding trends.

JXML2OWL Project is divided in two sub projects: JXML2OWL API, a library for mapping XML schemas to OWL Ontologies on the JAVA plaform. JXML2OWL Mapper, an easy to use standalone application with a graphical user interface using the JXML2OWL API.

this is a small project which provides several mathematical function useful for a chemist or somebody working with mass specs. The goal is to provide several cuda and c based functions which can be easily accessed using java, groovy and python.
