a parametric 3D CAD modeler
WARNING: FreeCAD has moved! FreeCAD code and release files are now hosted on github at https://github.com/FreeCAD/FreeCAD Only older files and code are available here. FreeCAD is a general purpose feature-based, parametric 3D modeler for CAD, MCAD, CAx, CAE and PLM, aimed directly at mechanical engineering and product design but also fits a wider range of uses in engineering, such as architecture or other engineering specialties. It is 100% Open Source and extremely modular, allowing for very advanced extension and customization. FreeCAD is based on OpenCasCade, a powerful geometry kernel, features an Open Inventor-compliant 3D scene representation model provided by the Coin 3D library, and a broad Python API. The interface is built with Qt. FreeCAD runs exactly the same way on Windows, Mac OSX and Linux platforms.
General Mission Analysis Tool
Do you want to go to Mars but don't know when to leave or how much to bring? Do you want to study Earth protection by planning a mission to a near-Earth asteroid? The General Mission Analysis Tool (GMAT) is an open-source space mission design tool to help you answer these and many other space flight challenges. GMAT is developed by a team of NASA, private industry, and public and private contributors. The GMAT development team is pleased to announce the release of GMAT version R2017a. For a complete list of new features, compatibility changes, and bug fixes, see the Release Notes. Below are just some of the new capabilities contained in this release. • New navigation data types • Preliminary Kalman filter • STK ephemeris propagation • Utility for managing data files (EOP etc.) • Collocation library • Preliminary API interface • Second level editing of navigation data

OCaml interface to FFTW3 -- the Fastest Fourier Transform in the West! (http://www.fftw.org/). The code is developed at https://github.com/Chris00/fftw-ocaml
A cross platform GUI for OBD-II interface device control. Currently supporting ELM327 devices, the app allows you to view and clear error codes, and view live data from the ECU. Packages available for Windows and Linux (deb or rpm)
Febrl (Freely Extensible Biomedical Record Linkage) does data standardisation (segmentation and cleaning) and probabilistic record linkage ("fuzzy" matching) of one or more files or data sources which do not share a unique record key or identifier.
Sail7 is a design and optimisation tool for sail performance.
Sail7 is an analysis tool based on the linear panel methods. It is a derivative of xflr5.
Fingerprint Imaging Software -- fingerprint pattern classification, minutae detection, Wavelet Scalar Quantization(wsq) compression, ANSI/NIST-ITL 1-2000 reference implementation, baseline and lossless jpeg, image utilities, math and MLP neural net libs
A Smith charting program. You can enter either discrete components or transmission lines, see the results on screen and/or generate Postscript output. Component values can be changed numerically or using scrollbars.
A graphical interface for solving exterior ballistics problems, based on the excellent GNU exterior ballistics library. This software generates valid 3-DOF solutions to small arms trajectories, including wind and atmospheric corrections.
SQS is the Simple Queueing System that allows jobs to be run in sequence on one or more machine. The queues can be inspected, jobs can be deleted from queues even when running, and jobs can be held. The latest version as at the end of 2011 is sqs-3.1.
SecondString is a Java toolkit for developing and evaluating approximate string comparision operators. It includes abstract classes for various edit-distance based comparators, concrete implementations of several published approximate comparators, a suit
A python gear generator that serves as CAE/CAD-preprocessor for involute gears based on pythonOCC. It allows for the computation of dynamic properties and the creation of exact geometries from a minimal input set.
