VStar is a multi-platform, easy-to-use variable star observation visualisation and analysis tool. Data can be read from a file or the AAVSO database, light curves and phase plots created, period analysis performed, and filters applied. Plugins can be developed, e.g. to make additional observation sources available.

Kim S et al, "Virmid: accurate detection of somatic mutations with sample impurity inference", Genome Biology 2013, 14:R90 http://genomebiology.com/2013/14/8/R90/abstract Virmid (Virtual Microdissection for SNP calling) is a Java based variant caller designed for disease-control matched samples. Virmid is also specialized for identifying potential within...

The TextProcessor Java package is a text processing toolkit, which provides some frequently used text processing functions such as stemming, removing stop-words, generating a term vocabulary, and calculating the term-doc frequency matrix. Basic topic mining models such as LDA and sparse NMF are also supported. The package can also generate feature files from a given text dataset with LDA and LIBSVM format for posterior procedures such as classification or clustering. The toolkit is also being extended for more advanced text analysis tasks based on natural language processing techniques.

Frequency Spectrum Dump Inputs: mp3, wav, ogg, flac, etc Scriptable, Visualization Output: csv file with the mean magnitudes of 255 frequency bands

Online Guitar Tuner java applet which analyse your microphone or any other sound input to find fundamental frequency using a Fast Fourier Transform. Classical "Vintage" design looking like real guitar tuners.

Maximally flat (maxflat) digital filter design in Java, with arbitrary numbers of poles and zeros. "Maximally flat" means that the magnitude frequency response has the maximum number of vanishing derivatives at 0 and pi.

A guitar tuner written in Java, comparing frequencies detected in the signal from the microphone to standard or user-defined notes. The number of notes tested and their frequency is configurable, so it can be used for other instruments and other tunings.

WikiVis is a tool to analyze Wikipedia based on several aspects. The main objective is to visualize the conclusions of this examination, which focusses on the editing frequency and relevance of articles and categories as well as the activity of users.

CryptoHelper is a Java program designed to aid in the decryption of classical ciphers, ie pre WWII ciphers. It brings together tools like frequency analysis, friedman tests, enciphering/deciphering for several clasical ciphers, and brute force algorithm

Our goal is to surpass the performance of the Matching Pursuit and Best Basis algorithms and provide progressive time-frequency analysis.

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.
