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.
The Repast Suite is a family of free agent-based modeling libraries.
The Repast Suite is a family of advanced, free, and open source agent-based modeling and simulation libraries that have collectively been under continuous development for over 10 years.
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.
Pascal Units for Medical Applications
The PUMA Repository is a collection of Pascal units for medical informatics. It contains reusable source code for a wide field of health-care application development. The code includes converting functions for measurement units and an HL7 engine. PUMA is compatible with Lazarus and Free Pascal. Some of the units also support other Pascal implementations including Delphi, winsoft Pocket Studio and other compilers.
