JREC is a framework for building finite state automatons from regular expressions based on a general grammar.

A Java application enabling users to create, edit, and view sports or competition results. In addition, there are facilities to view league tables and other statistical information based on the results.

The Linear Algebra class library for Java provides a full set of tools to programmers who need linear algebra operations to use in their own projects. Currently the library supports elementary matrix operations.

MTAC is a powerful, yet small and easy-to-use symbolic math program written in Java. It supports complex numbers, symbolic differentiation, numerical integration, plotting, and more.

Mark Six Analyst is a database of Hong Kong Lottery or so-called Mark Six. It provides a tool of various statistics method to show relationships between data and forecasts.

MathGenius is a graphical tool intended to simplify your work in mathematics. By now it includes a graphical function plotter, a mechanism (still in development) to derive functions, and an equation solver. An extension mechanism will be developed.

Java library for simple managing and solving sophisticated mathematic expressions and equations, based on Reverse Polish Notation (RPN)

This tool, described in the July 2006 issue of IEEE Computer, determines how many servers to install such that average request response time is 'x' number of seconds. The tool is a Java application that is used for server sizing efforts.

3-layer neural network for regression and classification with sigmoid activation function and command line interface similar to LibSVM. Quick Start: "java -jar nen.jar"

Program to convert numbers to and from binary, hexadecimal, octal and binary. Useful for scientific calculations and programmers.

NumberMonkey is a calculator written in Java, including basic operations and additional functions; new functions are added with each release. It can be implemented as a standalone desktop application or as an applet within a webpage.

OnlinePlotter is a graphical and interactive online function plotter to build customizable functions per Drag&Drop.

Can calculate mathematical expression. It have a module system witch make it very easy to add own functions. Other features are a graph painter and a tiny programming language designed too make it easy too write small mathematical tools.

Image processing tool that encodes pixel data as indices within the first 16.7 million digits of PI (π). Features high-performance Numba-accelerated search and a signature 'film-grain' aesthetic upon reconstruction. ZIP also include 16 MB file with 16,7 mil numbers of PI Benchmark(Single-Thread): Hardware & Environment Apple Silicon: Apple M2 (Mac mini/MacBook) x86_64 Platform: Intel Core Ultra 5 225F (Arrow Lake, 10 Cores) OS 1: Fedora 43 (GNOME) OS 2: Windows 11 Pro (23H2/24H2) Software: Python 3.14.3 + Numba JIT (latest) Results (Lower is better) Platform / OS CPU Time (Seconds) macOS (Native) Apple M2 52.151311 s (in default setup) Fedora Linux Intel Core Ultra 5 225F 58.536457 s (in default Power Management: Balanced) Windows 11 Intel Core Ultra 5 225F 59.681427 s (important!

This is a program that lets you graph numbers into a pie chart!

Plexus is a Java library with specifications and implementations for generic graph data structures. Like the Java Collections Framework, vertices and edges are containers for arbitrary user-defined objects.

Pulga is a program for numerical simulation of dynamical systems designed to provide students and researchers an easy way to model and qualitatively analyse their systems on a computer without the difficulty of traditional computer programming languages.

QCalc today is a simple calculator for the T-Mobile Hiptop, with the potential to be so much more.

RISO: distributed, heterogeneous Bayesian belief networks. Belief network: a probability model defined on an acyclic directed graph; distributed: nodes can be on different hosts; and heterogeneous: allowing different types of conditional distributions.

A program that makes Graphics and Tables of a formula for giving the aproximated value of a root.

SWire is a software interface enabling us to query Stata for the executing of basic operations like reading or writing data. The core of SWire is a Java plugin which functions as a server and it can be queried by using the HTTP protocol. SWire is in essence a wrapper around the Stata-Java API and all the functions relating to this API can, therefore, be externally called by clients. SWire can be interrogated on a local network and it accepts AJAX queries, thus enabling the development of web applications which provide the user with graphical user interfaces. For example, a web application running on a browser can interact with Stata on a local network; this application could be a data entry form or an automatic report. By providing a communication protocol, SWire makes it possible to connect Stata with many other applications for data exchange and basic interaction, thereby extending the capabilities of Stata. SWire requires Stata >=13.

Opensource software projects for genetics and genomics from Sage Bionetworks.

Java library of statistical distribution functions. Classes implement the PDF, CDF, and (usually) quantile and random variate generation for many common distributions.

Nowadays the idea of a music of the spheres, or a cosmic music that descends from the planets seems more like poetic philosophy than anything scientific. However, when the scientist Kepler discovered special principles about planetary motion, he also reconsidered the music. Apparently his observance of a harmonic law of planetary motion was reason for him to propose a computable system of pitch and harmony deriving from angular velocity. The purpose of the programming project is as a tool to examine his system. With Java 2, it provides an open-source solution for listening to harmonies so generated by planetary motion. This program can run on any computer provided with a Java Virtual Machine (Rev 1.5 or greater). JAVA 2, system independent. Purpose:to encourage research in harmony in astronomy, math and music. Obstacles:math, DSP/synthesis, networks, astronomy. Features:audio, database, graphics Technologies: Telnet, .WAV audio, oggvorbis, other audio
