GPS Manager (GPSMan) is a graphical manager of GPS data that makes possible the preparation, inspection and edition of GPS data in a friendly environment. GPSMan supports communication and real-time logging with both Garmin, Lowrance and Magellan receivers and accepts real-time logging information in NMEA 0183 from any GPS receiver. (more...)
Stellarium is a free open source planetarium for your computer. It shows a realistic sky in 3D, just like what you see with the naked eye, binoculars or a telescope. Stellarium is being used in planetarium projectors. Just set your coordinates and go.
Genius is a calculator program similiar in some aspects to bc and matlab. GEL is the name of it's extention language, in fact, a large part of the standard genius functions are written in gel itself.
Baudline is a time-frequency browser designed for scientific visualization of the spectral domain. Signal analysis is performed by Fourier, correlation, and raster transforms that create colorful spectrograms with vibrant detail. Conduct test and measurement experiments with the built in function generator, or play back audio files with a multitude of effects and filters. (more...)
Dr. Geo is a GTK interactive geometry software. It allows one to create geometric figure plus the interactive manipulation of such figure in respect with their geometric constraints. It is useable with students from primary or secondary level.
GAMGI is an object-oriented program aiming to handle all aspects directly related with building, viewing and analysing atomic strucures, such as molecules, crystals, glasses, liquids, etc. GAMGI supports the 230 crystallographic space groups, and can be used to perform point symmetry and 3D Voronoi analysis. (more...)
Chemtool is a small program for drawing chemical structures on Linux and Unix systems using the GTK toolkit under X11. Chemtool relies on transfig by Brian Smith for postscript printing and exporting files in PicTeX and EPS formats. Its companion program, XFig, is recommended for enhancing the output of chemtool, and for creation of 2D diagrams and schematics in general. (more...)
Structural Verilog compiler for UN*X operating systems. Some synthesizable behavioral constructs are now supported. An event simulator (vsim) is included for testing of logic designs. A cycle simulation compiler (cyco/csim) is included which can compile netlists into fast levelized C code. Cyco can also generate ABEL netlists that may be used for FPGA generation. (more...)
AutoSignalTM is the first and only program that completely automates the process of analyzing signals. Save precious time by eliminating the programming time normally required for performing sophisticated signal analysis. AutoSignal takes full advantage of its graphical user intuitive interface to simplify every aspect of operation, from data import to output of results. (more...)
PythonCAD is written entirely in Python. The goal of this project is to create a fully scriptable drafting program that will match and eventually exceed features found in commercial CAD software.
