Frink is a calculating tool and programming language designed to help you in the real world. It tracks units of measurement throughout all calculations and ensures that answers are correct. It converts between systems of measurement, and has a huge library of physical data. It is both a simple calculator for quick calculations and a full-fledged programming language for large tasks. It draws high-quality graphics, handles conversions between time zones, currencies, and historical values of the U.S. dollar and the British pound, translates between several languages, does date/time math, and more.
DISLIN is a high-level, easy-to-use plotting library for displaying data as curves, bar graphs, pie charts, 3D-colour plots, surfaces, contours, and maps. Several output formats are supported, such as X11, VGA, PostScript, PDF, CGM, HPGL, TIFF, and PNG. Plotting extensions for the interpreting languages Perl, Python, and Java are also supported for most operating systems.
Koalog Constraint Solver is a powerful constraint solver written in Java. It provides cutting-edge technology for solving satisfaction and optimization problems, including scheduling, time-tabling, resource-allocation, puzzles (sudoku.koalog.com is powered by Koalog Constraint Solver), and configuration (Koalog Configurator is powered by Koalog Constraint Solver).
Evolvica is an evolutionary computation framework written in Java. The aim of the project is to provide a toolkit that enables developers to create genetic/evolutionary algorithms with minimal programming effort. The toolkit has a modular architecture and is highly extensible. It includes a visual algorithm editor, a source code editor, and a debugger.
LayoutEditor is an IC/MEMS layout editor. It features all angle elements, a font generator, macros, Boolean operations, drc, netlist-driven layout, LVS, and cross-platform compatibility. Supported formats include Calma GDSII, OASIS (Open Artwork System Interchange Standard), DXF, CIF (Caltech Intermediate Form), Gerber, DEF/LEF, and many others.
VULCAN (Viscous Upwind aLgorithm for Complex flow ANalysis) offers computational fluid dynamics for subsonic speed through hypersonic turbulent reacting and non-reacting flows on a variety of serial and parallel computational platforms. The computational cost of propulsion flow analysis is reduced through the use of special turbulent wall treatments, multi-grid methods for elliptic and space marching schemes, and conditioning of the governing equations to reduce numerical stiffness. Physical modeling capabilities are improved through the inclusion of models for compressibility, Reynolds stress anisotropies, turbulent diffusivity, finite rate chemistry, and turbulence/chemistry interaction effects. VULCAN can simulate two-dimensional, three-dimensional, or axi-symmetric multi-block problems.
Scheture is a hierarchical schematic capture system with built-in netlisters for Spice and Verilog. It has built-in plotting for Postscript, HP PCL and HP GL/2 printers and plotters. It includes a set of symbol primitives, and allows user-defined symbol primitives to allow for extensive customization of primitive properties. The system supports wire buses and iterated instances. The system also supports global pins and implicitly connected pins on a specific sheet. Supported platforms include Solaris and Linux (32- and 64-bit).
Inlab-Scheme is an independent implementation of the algorithmic language Scheme and conforms to the R4RS and the IEEE Standard 1178. In addition to the language core, Inlab-Scheme has support for image processing which allows the implementation of OCR and image recognition applications. Inlab-Scheme comes with two built in graphic file format converters which convert the PATIMG patent file format and the ST.33 patent file format to multipage TIFF without decompressing.
