An OpenSource Least-Squares-Adjustment Tool
JAG3D is a simple tool to estimate geodetic 1d, 2d and 3d-networks by a least-squares-adjustment called Gauß-Markov model. For gross-error detection, the software supports common outliers tests (based on hypothesis testing) and robust L1 norm (BIBER estimator). Moreover, the software supports deformation-analysis on the observation level. This network adjustment application supports classic observations: - Distances 2D/3D, - Directions and/or azimuths, - Zenith angles, - Levelling difference as well as - GNSS-baselines 1D, 2D and 3D. Further feature (add-ons): - Coordinate-transformation (CoordTrans), - Form analyser (FormFittingToolbox), - Datum-transformation (UTM, Gauß-Krüger, Soldner; WGS84, Bessel, Krassowski, Hayford; NTv2 ...)
jChecs is an open source Java chess program, designed to introduce the basics of computer chess programming concepts.
Nesting SDK, Library
This is a SDK which can nest/layout the part/geometry/polygon on the material or sheet intelligently, you can get the best utilization of the materials, this SDK also support read/write DXF/DWG files and part-in-part nesting. New nesting lagorithm is implenmented, more good to support true shape part or material.
Lascer liefert zu einer Menge binär klassifizierter Attribut-Vektoren eine Menge von Regeln zur Beschreibung der Klassen. Die Regeln können auch mathematische Funktionen enthalten, deren Art vorgegeben werden kann.
Animal Algorithm Animation System
Animal is a Java-based system for visualizing and animating algorithms and data structures. Available since 1999, it is one of the established AV systems, and provides one of the largest collections of supported algorithms. Animations can be generated on the fly based on user input - for a large selection of algorithms and topic areas, including, but not limited to, the topic areas of backtracking algorithms, compression, cryptography, basing, searching and sorting.
Toolbox for Java developers. Includes right now only a multi-layered extensible cache system but will grow depending on requirements.
This simplesudodu program is intend for studying in the sudoku solution algorithm rather than a game (If you want to make it a game, it's OK ^_^). Later I will implement the 4*4 or other kinds. Different sudoku requires different algorithm to solve.
phonet4j is the port of a extensible, rule based algortihm for phonetic conversions written by Joerg Michael to java. His code was first published in the computer magazine c't (issue 25/1999, pp. 252). Includes two rulesets for the german language.
Fuzzy services deliver APIs for representing and processing fuzzy information.
Logi (Local Observations to Global Integration) transforms several local coordinate systems (composed of polar measurements) into a global spatial uniform network with respect to the Guide to the Expression of Uncertainty in Measurement (GUM).
Depending on a SICK lasescan and a created environment landscape a routing function will be implemented to give a robot a few waypoint to drive from a start point to a choosen destination.
The Simple RTF Writer (SRW) is a slim Java library which empower Java programms to create RTF ("Rich Text Format" - an alternative document format from Microsoft) documents and fill bookmarks and fields in existing RTF documents on any platforms.
a free cross platform calculator for calculating BIG numbers
BigAl is a free open source and platform independent software for calculating really BIG numbers. It supports not only standard arithmetic, but also exact period determination, predefined factorials, fibonacci with seeds, factorization, nth root, etc
IVS Reference Point Determination
Skalli is a simple tool to estimate the IVS reference point of an azimuth-elevation type VLBI radio telescope.
Structorizer is a little tool which you can use to create Nassi-Schneiderman Diagrams (NSD). Stuctorizer is written in Java and free for any use. The code has been moved to Github: https://github.com/fesch/Structorizer.Desktop
This project is an extended implementation of Knuth's "Dancing Links" algorithm and some use cases (e.g. Sudoku).
YACS (Yet Another Constraint Solver) is a Java library and an object-oriented framework for constraint solvers. It supports propagating and solving of constraint satisfaction problems with finite and infinite domains (discrete values and real intervals).
JaNaG is a Java random name generator for role-games, authors, and the like. It is based on a name fragment database that creates relatively reasonably sounding names. It can run as applet, GUI appliance, command line tool, or on a server-client basis.
A "limited lookup parser": stupid but assiduous tool for grammar developers. It generates all words for a given grammar up to a certain level of derivation steps and stores the results in a database. Thus the actual parsing process is a simple lookup task
SweenJet helps developers to create Java applications. It provides constrained models, useful Swing components (e.g. splash screen, input fields), actions, look-and-feel enhancements (e.g. themes, multi-line tooltip), and a complete preferences system. This project is no longer actively developed.
AMSF (Automated Model Selection Framework) provides Classifier/Predictor Selection for WEKA-Classifiers based on Meta-Learning. Selection is done via a rule-based Pre-Selection, followed by 'Zoomed Ranking'(as used in WEKA METAL).
TimeFinder automatically optimizes schedules (timetables) for universities and high schools. It makes manual timetabling for the timetabler easier via a Java GUI. Export+import is supported via xml and text formats. http://timefinder.sourceforge.net/
plausj a collection of checksum algorithms used to validate business keys like bank account codes or credit card numbers. It's compiled as JVM bytecode files (although it's not necessarily implemented in Java) and can be used on JRE 1.5 and later.
Programmieraufgabe 10 der Vorlesung Computerorientierte Mathematik I WS10/11 an der tu-Berlin.
The simpliZia-program implements the simplex-algorithm and is designed to help students of Operations Research to understand and learn the algorithm. This is a german project, source and program are actually written in german.
