NoteLab is an advanced "digital notebook" specifically designed for tablet computers. With its stroke smoothing, antialiasing, and "smart rendering," NoteLab provides a beautiful and powerful note taking environment on any operating system.

Java-based number generator package. Includes several strategies, apart from the usual random: constant, serial, function, composite. Besides, generators can be wrapped in different filters to obtain modified data series.

'Numeric Base Calculator' is a console application developed in java.It allows you to do conversitions and simple arithmatic operations involving the most commonly used bases like 2,4,8,10 & 16.You can convert a digit from one base to another.You can perform arithmatic operations like addition,substraction,multipication & division using those bases.This is a handy tool for you to check or do your homework!

Operations Research EXperiment Framework for Java

Java numerical analysis codes based on Didier Besset's "Object-Oriented Implementation of Numerical Methods: An Introduction with Java & Smalltalk", 2000, Morgan Kaufmann Publishers.

The ObjectVolume program calculates the volume, surface area and centroid of a closed triangular mesh represented in an object file (.obj). The process goes through the list of triangles that make up the surface and, for each triangle, forms a tetrahedron with an external point. The program uses the origin (0,0,0). The volume of the tetrahedron is then calculated. Tetrahedrons with back facing triangles are added and those with forward facing triangles are subtracted yielding the object volume. A detailed description of the process is presented in the ObjectVolumeTutorial.doc document as well as program logic and results. A key component in the program is a subroutine that calculates the volume of a tetrahedron. Four sets of equations were tested and to my surprise all four produced similar results in accuracy and timing.

Octave development environment built upon Eclipse's Dynamic Languages Toolkit (http://www.eclipse.org/dltk/). Distributed as an Update site for Eclipse 3.7 Indigo and Indigo-based package for several platforms. Supports search, autocompletion, launching scripts, interactive console, debug and integrated plotting on Octave versions 3.2.x, 3.4.x and 3.6.x. The current goal is to make it running out-of-box on multiple platforms. Currently only Linux and Windows are supported. Mac support is possible. The project needs a maintainer for Mac version, since I don't have Mac to build Octclipse and test it on this platform. Also, it is worth to support Eclipse 4.0 Juno with DLTK 4.

OPALE is an Open Source project which development is done at two different levels: the OPALE library: which is a scientific library written in Java and which is composed of different modules (tools, swools, mathtools,...). Its purpose is to give

Opt4J is an open source Java-based framework for evolutionary computation. It contains a set of (multi-objective) optimization algorithms such as evolutionary algorithms (including SPEA2 and NSGA2), differential evolution, particle swarm optimization, and simulated annealing. The benchmarks that are included comprise ZDT, DTLZ, WFG, and the knapsack problem. The goal of Opt4J is to simplify the evolutionary optimization of user-defined problems as well as the implementation of arbitrary meta-heuristic optimization algorithms. For this purpose, Opt4J relies on a module-based implementation and offers a graphical user interface for the configuration as well as a visualization of the optimization process.
