A general OWL reasoning framework for the analysis of big biomedical data and implement a MapReduce-based property chain reasoning prototype system. OWL reasoning method is ideally suitable for problems involved complex semantic associations because it is able to infer logical consequences based on a set of asserted rules or axioms. MapReduce framework isused to solve the problem of scalability. In our experiment, we focus on the discovery of associations between Traditional Chinese Medicine (TCM) and Western Medicine (WM).

Semantic query optimization (SQO) is the process of finding equivalent rewritings of an input query given constraints that hold in a database instance. We present a Chase & Backchase (C&B) algorithm strategy that generalizes and improves on well-known methods in the field. The implementation of our approach, the pegasus system, outperforms existing C&B systems an average by two orders of magnitude. This gain in performance is due to a combination of novel methods that lower the complexity in practical situations significantly.

Framework: Project for Evolutionary Predator Prey Algorithms, used to implement an evolutionary scheme based on the developement by van Laumanns. Implement testproblems, special behaviours, environments, and other yet not known features.

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.

PileWorks provides the organizational structure for coordinating several different projects which approach some aspect of Pile Technology. PileWorks defines a set of interfaces and implements some basic infrastructure for Pile engines and agents.

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.

General purpose state observation library for Plan Old Java Objects. It enforces Model-View-Controller paradigm, has well defined API and set of ready made implementation algorithms.

Programmieraufgabe 10 der Vorlesung Computerorientierte Mathematik I WS10/11 an der tu-Berlin.

This is a Su-do-ku game solver and player. It generates a complete Sudoku.

quadGT is a software package for the joint genotyping of two parents, child’s normal genome and child’s tumor genome based on sequencing reads aligned to a reference genome.

Sample code, algos, what you got?

Red-Black Maps and Trees, written in Java. These Classes try to advoid the overhead produced by Sun's implementations. For example Trees are just Trees, nor self mapped Maps. Access on nodelevel is possible, reducing overhead while iterating over an map

reputron is a knowledge extraction engine platform that covers all aspect of text mining, relevance, indexing and querying on a corpus of text documents.

Meaningful acronym and name generator from a list of keywords provided by the user. The software checks that the random words generated exist in the specified language by checking against a spelling engine publicy available as a web service

sdf4j is a Java framework to manipulate Static Dataflow graphs (SDF).

a first work algorithm trials to implement a compromise between distributed and centralized version control system.part of research project,it's only a simulation. no real networking is implemented ,only virtual random signal are imaginary produced.

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.

A base set of libraries. Boilerplate type code and algorithms. Currently skuttil (Java util & parsing code) and searKit (generic Java search framework).

This application implement an approach for doing keyword based search over semi-structured data available in HTML pages.

Small software suite for text string manipulation using well-known algorithms. Coded for academic purposes.

swIMP (swig-based Interfaces for Mathematical Programming) provides Java wrappers for solvers written in C or C++. The current focus is on accessing OSI-compatible linear programming (LP) solvers from the Coin-OR-project (e.g. Clp, GLPK, MOSEK, CPLEX).

this library implements distributing algorithms for genuine computational POJOs (aka. jobs dispatching). it deals with reliability, synchronization and ordering. it has well defined api targeted at easy integration within existing code.

Textcrypter is an encryption tool using vigenere cipher algorithm. Vigenere use the same key/password to encrypt and decrypt a file (symmetric key cryptosystem). Result of the encryption process is a ciphertext in hexa number.
