Trans (short for Transmuter Programming Language) is an extremely dynamic, biologically-inspired prototyping language providing a framework for experimenting with naturally evolving systems of objects over the net, and for exploring new ideas about recombinant software, code morphing, and evolutionary programming. Trans is also a very capable general-purpose programming language. It's fast, flexible, compact, object-oriented, highly extensible, and easy-to-learn. It can be used for rapid prototyping, or as a scripting language, an embedded language, a network server or client, a system of cooperating network nodes, a real-time control and monitoring system, and more.
CellProfiler is a system for analyzing cell images. It is designed for biologists without training in computer vision or programming to make quantitative measurements of cells in thousands of images automatically. It is implemented using Matlab, but compiled standalone versions are available.
SOFEA is a Matlab object-oriented Finite Element toolkit. It includes the book, A Pragmatic Introduction to Finite Element Analysis for Structural Engineers. The toolkit provides linear transient thermal analysis capabilities, with stress analysis and coupled multi-physics coming shortly.
SINGULAR is a computer algebra system for polynomial computations in commutative algebra, algebraic geometry, and singularity theory. Its main computational objects are ideals and modules over a large variety of baserings. The baserings are polynomial rings over a field (eg. finite fields, the rationals, floats, algebraic extensions, transcendental extensions), or localizations thereof, or quotient rings with respect to an ideal. It features fast and general implementations for computing Groebner and standard bases, including Buchberger's algorithm and Mora's Tangent Cone algorithm. Its interactive shell and C-like programming language can be extended by libraries written in the SINGULAR programming language.
nMicrocoder is an ncurses EDA tool to write microcode. Basically, it is a stripped down spreadsheet program that lets you fill a table with "0", "1", and "-", and gives you compile-ready verilog code in return. It was written as an alternative to full spreadsheet programs. It is known to run on Linux, IRIX, and Solaris, unless ncurses 5.3 is installed.
VisIt is an interactive parallel visualization and graphical analysis tool for viewing scientific data. Users can quickly generate visualizations from their data, animate them through time, manipulate them, and save the resulting images for presentations. VisIt contains a rich set of visualization features so that you can view your data in a variety of ways. It can be used to visualize scalar and vector fields defined on two- and three-dimensional (2D and 3D) structured and unstructured meshes. It was designed to interactively handle very large data set sizes in the terascale range, and works well down to small data sets in the kilobyte range.
Sh is a programming language built on top of C++. It can be used to write shaders that run on top of modern graphics processing units (GPUs), or write stream programs that run on GPUs or CPUs. It is implemented as a C++ library, and allows programs to be generated at run-time using a number of metaprogramming techniques. Variants of programs for different cases can easily be generated, or programs can be generated entirely at run-time from some input data. The system is cleanly separated into a frontend and backend, and is hence portable.
