The application Crimeblips provides up-to-date crime statistics for Berlin (Germany). It maps and visualizes crimes, allowing users to identify crime hot spots, trends and general patterns. Bayesian algorithms are used to extract relevant information.
Vehikel is a learning environment for behavior based control of mobile robots. A little bit artificial intelligence based on a domain specific language for the c't Bot.
x2svg is software to graphically lay out files like XML Schema, DTDs and Java property files as scalable vector graphics (SVG). Diagrams can be converted into PDF, PNG, TIF and EPS files directly from within x2svg. A simple GUI and ant integration exist.
TOAST (Trust Organisational Agent System Testbed) is a simulation framework used to evaluate and compare different trust models for agents embedded in organisational systems.
JMapDesk is a Java-Swing application to the UMN MapServer on the base of the shp2img tools (FWTools) similar to Sourcepole's Mapdesk. The UMN MapServer is a well known online map server software. MapServer is being configured through a so called Mapfile
This program will read in data generated by ABI DNA Analyzers using GeneScan or GeneMapper, CEQ 2000 and SCF instruments and construct gel images which are straightened and sized. Please download and view the tutorial, no documentation is included in 2.1
LT4eL (Language Technology for e-Learning) develops a framework of multilingual language technology tools and semantic web techniques for improving the retrieval and the metadata annotation of learning material.
This project tries to find geographical locations (formulated by GPS positions) for specific queries (eg 'art') in specific environments (eg 'Maastricht') by analyzing webpages.
TimeSleuth discovers temporal decision rules. It also judges the (a)causality of the rules. TimeSleuth can discover rules that involve time: {if (rainy_yesterday = true) then rainy_today = true}, or {if (rainy_tomorrow = true) then rainy_today = true}.
trakkcor tracks your position via gps and submits the position data to your server. All you need is a j2me-compliant mobilephone which supports JSR-82 and an external gps receiver.
