Spice+ is a general-purpose circuit simulation program, based directly on SPICE 3F.5 from the University of California (Berkeley). An improved version of Spice for DOS, Windows and Linux. http://spicep.sourceforge.net

SPECI-SPICE is a subset of SPICE intended to run on low powered computers like Amstrad CPC, ZX Spectrum, CP/M machines, old PC machines, some programmable calculators,etc. by keeping most important functionality of SPICE 2.

Production (3 level) Programmer for Microchip PIC on Win9X,DOS,NT,Win2K. Flash and Eprom, 14 and 12 bit devices. Printer Port programmers and the BEL In-circuit Dual PRODUCTION Pic Programmer board.

Program for viewing, editing, manipulating, and analyzing absorbance spectra. Simple arithnetic includes making linear combinatins of up to 10 spectra. Advanced functions include fitting spectra as LC of standard basis spectra, singular value decomposition, Fourier transform, differentiation, integration, global fitting of 3D titration and kinetic data. Graphics features allow composing Figures and export to postscript files which can be converted to pdf, imported into photoshop for rasterization, or used in page design software like Illustrator.

Stripe Snoop reads the contents of a magstripes (Track 1, 2, or 3) through different hardware interfaces and not only displays the contents, but uses a CDDB-like database of card formats to try and figure out what the contents mean.

Modernizing the sentential and predicate logic programs, Bertie and Twootie, by cleaning up the code, rewritting the code to conform to the standard Pascal defination, and developing a graphical user interface for both X and MS Windows.

Iterate is an implementation of the Bravais-lattice-finding algorithm from: Andrews and Bernstein, Acta Cryst. (1988). A44, 1009-1018 Lattices and Reduced Cells as Points in 6-Space and Selection of Bravais Lattice Type by Projections.

XFUNC 2.2 is a IBM PC program for DOS. It is an aid to Electronics Engineer who calculates transfer functions using symbolic algebra. It compute the frequency domain transfer function of a circuit in symbolic format, given a circuit description netlist in linear model. Calculate AC or DC symbolic transfer function in S-domain for Linear Circuits or Z-domain for Switching Circuits. Accept resistors, capacitors, inductors, dependent sources, ideal opamps, and ideal switches. Component values can be real numbers, symbols, or user defined symbolic expressions. Frequency domain results can be transformed to time domain via Inverse Laplace or Z Transform. Transformation between S-domain and Z-domain results can be done via Forward or Backward Derivatives (Euler Transform), Bilinear, or Impulse Invariant Transforms. Provide Bode, Gain-Phase, Nyquist, Pole-zero, Impulse, and Step response plots. Plot ranges can be set manually or automatically.

Common Hardware Recovery Solutions by Ukrainian-Russian network

kalc is a programmable scientific calculator, using RPN (Reverse Polish Notation). Its behaviour imitates a HP48/HP49 calculator. Works with real and complex numbers, unlimited size integers, arbitrary-precision real numbers and more.

ABE is a small, fast and convenient program for visualizing and modeling experimental bioassay data. The data can be modeled using either polynomials or a more specific four-parameter model based upon the standard, sigmoidal dose-response curve.

Compasso é um programa desenvolvido em C para o controle de motores de passo através da porta paralela (LPT). Juntamente com o programa é disponibilizado um esquema com uma montagem de circuito para ser utilizado.

Digitizer program to manually digitize data from graphic images. Allows for multiple calibrations and source image files for a single set of data series. Also includes an auto-export feature to streamline interoperability.

Real-time EEG data acquisition and control software for event related potential (ERP) researchers. Writes data in ERPSS (UCSD) raw and log format and displays, in real time, in X windows.

This is a project that simulates the German Military Enigma machine during WWII.. It is a project for beginers to learn to program and to meet people. If anyone is interested in helping, please email me @ dustin@rockhill.org

Equalculator is an equation calculator. It is currently in the "pre-alpha" stage of development, so don't expect it to do miracles. You type in your equation, it will ask you for the variables and Voila!, it gives you the answer.

FreeBasic Math library

Nice and handy tool for phisicists and any other scientists who need some math. This project contains DOS application with GUI made with BGI and can draw functions in 2D and 3D, approximate with least square method and build histogram (more in future ;)).
