Scientific Java Calculator for cell-phones and MIDP devices

DragMath is a drag and drop equation editor in the form of a Java applet. Once an expression is created the user can convert it into a variety of different linear syntax for mathematics, including MathML, LaTeX, Maple, Maxima or any user defined style. PLEASE NOTE: active code development has moved to GitHub. https://github.com/maths/dragmath

Matrex is a lightweight vectorial spreadsheet: calculates blocks of values, not single cells; it is strongly multithreaded; users can work together on sheets using a server. Adapters to matlab, scilab, octave, R.

Tuatara Turing Machine Simulator is a graphical tool for designing and executing Turing Machines. Designed primarily for teaching purposes, it features a simple point-and-click interface.

JSci is a set of open source Java packages. The aim is to encapsulate scientific methods/principles in the most natural way possible. As such they should greatly aid the development of scientific based software.

IDL specified API for manipulating and processing CellML 1.0 and 1.1. Includes C++ implementation. Accessible from a C++ program, or from any language for which a CORBA language mapping is available Also, a Java wrapper of the API is available.

Parallel Spectral Deconvolution is a multithreaded ImageJ plugin for spectral image deblurring.

Statcato is a Java software application for elementary statistics. Its features include data and graph generation, probability distributions, descriptive statistics, confidence intervals, hypothesis tests, correlation, regression, and analysis of var

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

A java program for exploring cubic fractals, similar to the Mandelbrot set but exhibiting a higher level of dynamical complexity. CubicBrowser provides the ability to explore the 4D Cubic Locus (and associated Julia sets) by viewing arbitrary 2D slices.

FrAid(FRactal AID) is an interface to Java, allowing it to proc. math. data(functions/equations). A compl. standalone system utilizing the FrAid prog. lang. is available(no need to be Java programmer to use it!). Use instead of Matlab. High res. graphics

Franklin Math is an open source Java symbolic computer algebra system (CAS), with similarities to commercial math packages such as MATLAB or Mathematica. It allows numeric and symbolic calculations, with built-in functions including plotting commands.

Starting off as a simple LISP command in AutoCAD this HAVC pipe size calculator was migrated to a standalone Java application. Calculates HVAC minimum pipe ID based on GPM and FPS for numerous fluid types (found in the fluid density chart on EngineeringToolbox.com) Includes a table to automatically calculate riser piping sizes per floor. Read the README.txt file included in PipeSize.zip for instructions.

Gavrog stands for "Generation, Analysis and Visualization of Reticular Ornaments using Gavrog". It is a Java library together with a suite of interactive applications for the study of periodic net-like structures in space and their applications.

[EN] GraficoAR is a lightweight, pure Java application for 2D mathematical function plotting and real-time analysis. Built with Swing without heavy external libraries, it features a custom recursive parsing engine that respects operator precedence (+,-,*,/). Features: dynamic Cartesian graphing, adaptive grid zooming/labeling, numerical differentiation (plots the 1st derivative in blue), and definite integration (Riemann sums with text output and transparent blue geometric shading under the curve). Includes angle unit toggle (Rad/Deg) and a portable stand-alone version with bundled JRE. [IT] GraficoAR è un'app Java leggera per lo studio e il tracciamento di funzioni matematiche 2D. Sviluppata in Swing senza librerie esterne, usa un motore di parsing ricorsivo (+,-,*,/). Offre: grafici cartesiani dinamici, zoom con etichette assi adattive, calcolo della derivata (linea blu) e dell'integrale definito Supporta Gradi/Radianti.

HorsePower is J2ME scientific calculator optimised for use on mobile phones, with the appearance of the classic range of Hewlett Packard calculators. (MIDP 1.0 & CLDC 1.0)

Graphical front-end for GNU Octave. Edit formulas in mathematical notation. Uses Octave (Matlab clone) as a math engine.

QMC Logic Minimizer is a versatile application for fast simplifying truth and reduce lines tables. This program offers a comfortable user interface for generating and minimizing of the combinational logic functions. It is unique for its possibility of minimizing several functions at the same time. This program is intended for practical digital devices constructors as well as formal scholars and academics. Features: - You can minimize up to 16 input variables and up to 16 output variables. - You can also reduce the number of table rows. - It allows you to name the input and output variables. - The table can be exported to HTML file and then you can use it in e.g. MS Word. - This program provides a comfortable interface, you can change fonts and colors. - It works on MS Windows, GNU/Linux, Mac OS.

SystemDynamics is a graphical Java application for modeling, visualization and execution of System Dynamics models.

GSH builder is a free Galois Sub-Hierarchy visualization tool. The algorithm for calculating GSH is called Pluton and the present Java realization is based on two articles. "Efficiently computing a linear extension of the sub-hierarchy of a Concept Lattice" by Anne Berry, Marianne Huchard, Ross M. McConnell, Alain Sigayret and Jeremy P. Spinrad. "Performances of Galois Sub-hierarchy-building algorithms" by Gabriela Arevalo, Anne Berry, Marianne Huchard, Guillaume Perrot and Alain Sigayret In you're in need of other GSH algorithms or their realizations in C++, you might want to investigate a project called Galicia on sourceforge. This program is free software and is licensed under GNU General Public License as published by the Free Software Foundation. Only jre7 compliant at the moment.
