The Quantitative Finance Framework (QFF) supports the development of software libraries in mathematical finance. The main field of applications are the pricing of derivatives and the management of financial risks.
PSIGHOS is a Java-based simulation library. PSIGHOS is focused on the simulation of business processes and comprises a parallel core so to reduce the execution time for large models.
This project provides a java implementation of the Captcha project ( see http://www.captcha.net ). A CAPTCHA is a program that can generate and grade tests that: -Most humans can pass. -Current computer programs can't pass.
Siafu simulates individual agents and their context, from home to city-wide scenarios. As a developer, you use the API to write your simulation for the purposes of data-set generation, test or visualization, optionally hooking it to your own application.

An Open Source portable pure Java game library with example games, Swing-based sprite animation engine, deployment framework, and firewall tunneling networking. The code is documented in the book Advanced Java Game Programming by David Wallace Croft.
IDEA (Interactive Display for Evolutionary Analyses) augments PAML with a graphical interface, phylogeny reconstruction using PhyML or PHYLIP, convenient and efficient parallel processing and visualizations.
A collection of tools for working with the comparative data analysis ontology including import/export facilities for common phylogenetic file formats, and also a triple-store framework.
This projects hosts the worlds fastest algorithms for the labeling of point-features. It especially looks for algorithms thar are free of constraints, applicable to many scenarios (e.g., visualization, maps...) and do not need any preprocessing.
A Java library and set of tools to quickly and easily manipulate graphs (set of nodes and edges) and dynamic graphs. The principal trait of this library is its ability to manage (create, edit, layout, display) continuously evolving graphs.
The development of this project now takes place on Github. Visit the official Graphstream website at http://graphstream-project.org
A generic SQL driven data audit tool for detecting differences between any JDBC accessible database tables and other data sources. Platform independent. It's a unix like diff for databases. Produces key values with the differing column name and data
DbViz produces plots of data contained in MySQL databases. Data can be viewed by looking at line graphs, xy scatter plots, and bar graphs. This greatly simplifies data analysis.
JGraph is the most powerful, lightweight, feature-rich, and thoroughly documented open-source graph component available for Java. See the project homepage at www.jgraph.com for information and downloads.
CThruView is an image viewer that allows mouse clicks to go through the image. Use it as tracing paper or splash screen. The image can be made semi-transparent, flipped, rotated, zoomed, always on top, clipped, moved, hidden and centered.
JSatTrak is a Satellite tracking program written in Java. It allows you to predict the position of any satellite in real time or in the past or future. It uses advanced SGP4/SDP4 algorithms developed by NASA/NORAD to propagate the satellite orbits.
Interactive visualization and analysis tool for large, multidimensional data sets. NDVis integrates with databases and allows users to create visualizations by writing queries. It uses dimensional stacking, pixelization, and interaction techniques.
Nounou is a Java library for handling optical imaging data. The core consists of a modular stream of "filter blocks" that each modify or display the data. It is easily called from Mathematica and Matlab, for advanced figure output.
PaloKettlePlugin is for Pentaho Data Integration aka Kettle. It's a Cell Input und Output Step for Palo Molap. The first code was developed by mybiq/3A-Strategy, the PDI-3 version has been developed by Stratebi. Now by 3A-Strategy and Litebi for PDI
Graph visualization using hyperbolic geometry (hyperbolic trees, but also general graphs).
Applications cover web site structures, topic maps, organisational charts and wikis.
