WavePacket (C++/Python)
Time-dependent simulation of open and closed quantum systems
Note: This package has been superseded by a Python-only package. See https://github.com/ulflor/wavepacket for the follow-up project. WavePacket is a program package for numerical simulation of quantum-mechanical wavepacket dynamics of distinguishable particles. It can be used to solve single or coupled time-independent or time-dependent (linear) Schrödinger and Liouville-von Neumann-equations. Optionally accounting for the interaction with external electric fields within the semiclassical dipole approximation, WavePacket can be used to simulate modern experiments involving ultrashort light pulses in photo-induced physics or chemistry. ... -

Timewave Synthesizer
A binary waveform synthesizer based on Timewave Zero
...His theory proposes that the structure of time is a complex wave with a scalar potential, and the King Wen sequence of the I Ching is the 64 hexagram code from which the waveform of time is derived; that the King Wen sequence maps the linear progression of the human states of mind, which ultimately substantiates this waveform. This theory is the basis for the well-known novelty computer program he and others had developed. This program synth was made in supercollider. -

Network tee program
Pass a data stream through a distribution tree using a daisychain method that typically runs at full network speed between each pair of nodes. On each node the data stream may optionally be directed to a local file or pipe. The topology of the distribution tree may be linear or branched, but will in either case contain only one "root" node. -

dosbox-ppcjit
DOSBox + PowerPC JIT = <3
...This version does not run on Intel Macs, and is not intended to run under Rosetta (use mainline DOSBox or Dominus' SVN builds instead). Suggested settings are included as a Preferences file. You should copy this to ~/Library/Preferences/DOSBox SVN Preferences before starting the program. All versions are built using Xcode 2.5 with -O3 -fsched-interblock -ftree-loop-linear. The G5 version has additional flags for better performance on the 970. All versions include SDL 1.2.15 and libpng. There is no support for this or any SVN build of DOSBox.

TrackingExample
This project presents simple marker detection and 3D augmentation
This is a project demonstrating tracking of a marker consisting of 6 blobs placed on a black palette and drawing a virtual house on it. Detection of the marker and augmentation (drawing of the house) are done in real time. Image from almost any internet camera can be used. The program is using incremental tracking, in which the position of the marker in the previous frame is used to improve the detection. The homography calculation needed for the augmentation can be performed using 4 different methods: -Direct Linear Transform, -basic OpenCV algorithm -OpenCV RANSAC based algorithm -OpenCV Least-Median based algorithm. ... -

CQU
Decision solver for Counting Quantifiers over Unary Predicates
...It also accepts Universally quantifies sentences over unary predicates, which are presented in the form of propositional clauses (classical Boolean logic clauses). This implementation employs minisat as the SAT solver. It also emplouys COIN-OR Clp linear programming solver, and inherit from it. Given a CQUSAT instance in normal form as input, the program returns a solution, if there is one. The implemented method employs dual Simplex Algorithm with Column Generation. At each iteration, a SAT instance is generated and a SAT Solver (minisat) decides its satisfiability. Details about CQUSAT, its normal form and this turing reduction can be found in the paper "CQUSAT.pdf" that comes with this package. ... -
