ExactCalc
Software for exact computing based on interval arithmetic.
1/3 is not 0.33. Pi is not 3.14. Actually 1/3 is in interval [0.33, 0.34] and pi is in interval [3.14, 3.15]. During computation truncating error is accumulating. At end of computation it is needed to know real boundaries of result. The solution is given by interval arithmetic. Simply speaking, because 1/3 is in interval [0.33, 0.34] and 1/7 is in interval [0.14, 0.15], value 1/3 - 1/7 must be in [0.18, 0.2]. Computation can be arbitrary long and complex but interval arithmetic gives... -

illustrative_progs
collection of illustrative programs:small games, simulators: C, Matlab
...Browse the files, don't click on widnload because there are multiple zips!! All are related to rigidbody dynamics used to make vehicle simulators in the simplest way. Other types of programs may figure too: Snake or Tetris in C for showing the C programming style opted for the other, more specific programs. Possibly this is a link for supplying material to some Wiki articles related to videogames and gamep-physics. -

SphereSim
Physical simulation of particle movements
...By forces (such as gravity in a particular direction and between the particles, repulsion of the particles against each other and from the walls, Lennard-Jones-Potential between particles) different physical effects in particle groups are calculated and shown, such as the Brownian motion. The application uses the programming language C++ and the Qt, OpenGL and OpenMP libraries. -

nevesim
NEVESIM is an event-driven neural simulation tool.
NEVESIM is a software package for event-driven simulation of networks of spiking neurons with a fast simulation core in C++, and a scripting user interface in the Python programming language. It supports simulation of heterogeneous networks with different types of neurons and synapses, and can be easily extended by the user with new neuron and synapse types. To enable heterogeneous networks and extensibility, NEVESIM is designed to decouple the simulation logic of communicating events (spikes) between the neurons at a network level from the implementation of the internal dynamics of individual neurons. -

prog89s52
Utility for programming an AT89S52 via a parallel port.
prog89S52 is a utility for Linux on the PC, allowing programming of Atmel's AT89S52 microcontroller via the parallel printer port. Atmel's 89S are programmable via an SPI port and therefore require absolutely no additional components in order to program them in-system. This program requires a standard "Centronics" type PC parallel port (a bidirectional, EPP or ECP port is not required). A 5-way cable is required to connect the microcontroller to the port; wiring information is given in... -

The Safe C Library provides bound checking memory and string functions per ISO/IEC TR24731. These functions are alternative functions to the existing standard C library that promote safer, more secure programming. The ISO/IEC Programming languages — C spec, C11, now includes the bounded APIs in Appendix K, "Bounds-checking interfaces".

A parallel-programming framework for concurrently running large numbers of small autonomous jobs, or microthreads, across multiple cores in a CPU or CPUs in a cluster. Each microthread is conceptually similar to a task in Ada and it is much lighter weight than an operating system thread. SpikeOS was designed to handle millions of microthreads, for example in a neural network hosting millions of spiking model neurons. SpikeOS handles microthread scheduling, synchronization, distribution...

Detection of homologous recombination events from SNP data
This software detects homologous recombination events (HREs) from SNP data. Based on SNP alleles calls and locations, it breaks the genomes into locally colinear blocks, and looks for cases where SNPs do not agree with the vertical pattern of inheritance in a phylogeny. It applies a dynamic programming algorithm to model whether changes within a block are likely a result of mutations, sequencing errors, or HRE. We use information from the nearby SNPs, so that if 1-2 alleles in a series of... -

Network Emulator
Distributed Network emulation tool for high rate packet
I need your help: In order to make this framework easier and more useful, I need your contribution. The idea behind this framework is to develop a GUI like GNS3 and make this framework more stable. So if you are interested and have C/C++ programming skills, please contact me at zahid.med@gmail.com This framework allows to emulate a network by managing ethernet packets coming from two kind of interfaces: UDP and virtual network card. This tool is similare to dynamips (GNS3) but it can manager a higher packet rate. It can help to study DDoS attacks based on Botnet using the Lightweigth C++ Virtual Machine (LwCVM) in order to emulate Bots. ... -

XCTruck3D _Truck
realistic truck simulator with 3D graphics done from zero
A truck/car simulator,with realistic physics and oldstyle graphics: it displays pixels through the SDL graphics routines, or the X11 if using that version (has some issues:so use the SDL ver).While the 3D graphics is done by the program itself without external libraries.The environment is a hilly terrain:total freedom to drive around.A remake of the classic "Terep 2". Written in the C programming language: although the code is 30 pages long, it's simple. Trailer can be detouched pressming 'l' (minuscle ELL) so to drive a normal car. There's an OpenGL version too: see the CTruck3D _Open,and an ASCII-Art ver (Term_ CTruck3D). This is also a good dydactical software: code is easy to undersand,and drawing procedures and physics sim procedure are written from 0 so it's clearly understandable how a complete 3D game is done in C, starting from a blank page of any plain text editor.Only basic knowledge of C was used. ... -

NKA
Nonlinear Krylov acceleration of fixed-point and Newton-like methods
Nonlinear Krylov Acceleration (NKA) is a method for accelerating the convergence of fixed-point (Picard) iterations. Many Newton-like and inexact Newton methods are fixed point iterations. The NKA project provides the canonical implementation of the method for several programming languages. The black-box accelerator is simple to integrate into existing code. Placed in the iteration loop, it observes the sequence of solution updates and replaces them with improved updates using information... -

lagrange_simulation_mechanics
simulations with Lagrangian method,both symbolic and by numeric deriv
...Simulation with Lagrangian method, both symbolic, and by numerical derivation. All well-grouped in folders. there is also a 'review' in 3 demos of the Newtonian dynamics: mass-spring systems. most of progs are written in C, with use of SDL lib to display simple graphics and have real-time interactivity. As to programming complexity, it's very simple... this all aims at classical physics simulation in a simple but efficient way. The numeric stuff really just illustrate the use of a real little physics-engine aimed at articulated body simulation... that's the funnest part of it: but of course much more is coming. ... -
