Open Source Solid Modeling CAD
BRL-CAD is a powerful cross-platform constructive solid geometry solid modeling system that includes an interactive geometry editor, ray-tracing for rendering & geometric analyses, network distributed framebuffer support, image & signal-processing tools.
Ngspice project aims to improve the spice3f5 circuit simulator.
A multi-platform collection of C++ software libraries for Computer Vision and Image Understanding.
Wcalc is a tool for the analysis and synthesis of electronic components. Some of the models include coupled microstrip lines, single layer air core solenoid inductors, etc. Wcalc can analyze the electrical parameters based on the physical dimensions a
Earth orbits and coverage display in 3D on your laptop.
SaVi - simulate Iridium, Globalstar, O3b, Sirius Radio, GPS, Galileo and other satellite constellations, modify them, or design your own. Uses Tcl/Tk and Unix libraries; 3D viewing option requires Geomview running on X Window.
FTimes is a system baselining and evidence collection tool. The primary purpose of ftimes is to gather and/or develop topographical information and attributes about specified directories and files in a manner conducive to intrusion and forensic analysis.
simulated annealing optimization and importance-sampling
Adaptive Simulated Annealing (ASA) is a C-language code that finds the best global fit of a nonlinear cost-function over a D-dimensional space. ASA has over 100 OPTIONS to provide robust tuning over many classes of nonlinear stochastic systems.
MatLisp is a package for Common Lisp for handling matrices with real-valued or complex-valued elements. BLAS is used for elementary matrix operations and LAPACK is used for linear algebra routines.
FLENS (Flexible Library for Efficient Numerical Solutions) is a C++ library for scientific computing. It can be considered as a very convenient and --- at the same time --- extremely efficient interface for BLAS and LAPACK. But it is much more than this
XDAQ is a software platform designed specifically for the development of distributed data acquisition systems. The development is carried out at CERN, the European Organization for Nuclear Research. Please visit http://xdaq.web.cern.ch
Clearcut is an open source implementation of the Relaxed Neighbor Joining (RNJ) algorithm, an efficient distance-based phylogenetic reconstruction method.
H2O is a collection of C routines and applications designed for the optimization of multi-reservoir and multi-period hydrothermal power production scheduling. H2O is built upon nonlinear network algorithms and heuristic techniques for higher efficiency.
IC CAD tools, documentation, scripts, and libraries for designing high-performance ICs, including SUE for schematics, MAX for layouts, DPC for datapaths and MCC for megacells. Prebuilt binaries for Linux, Sparc-Solaris, and HP-PA.
A simple mobile-agent library supporting agents written in C embedded in XML.
Multicore SWARM (Software and Algorithms for Running on Multicore Processors) is an open source library for developing efficient and portable implementations that make use of multi-core processors. David A. Bader (Georgia Tech) began SWARM in 1994.
