Compression Springs

These functions implement the 3D SPIHT algorithm, used for the compression of 3d wavelet coefficients. Such 3d wavelet coefficients are produced during the coding of video sequences. Platforms: Matlab

AC for text compression, code is a conversion from C written by witten Neal and Cleary " AC for DATA COMPRESSION " Platforms: Matlab

Used in image compression, the haar transform is an alternative to the DCT transformation. This file compute an n*n Haar matrix. (same use as "dctmtx") Platforms: Matlab

This software tool compresses a fuzzy system with an arbitrarily large number of rules into a smaller fuzzy system by removing the redundancy in the fuzzy rule base. As a result of this compression, the number of on-line operations during the fuzzy inference process is significantly reduced... Platforms: Matlab

A very simple droplet that performs tar-gzip compression on files and folders. The compression doesn't affect or modify original stuffs, by the way the compressed files will loose Mac OS specific resources (including type, creator and icon) and privileges (owner and group). This droplet becomes... Platforms: Mac

The Ejs Coupled Oscillators and Normal Modes model displays the motion of coupled oscillators, two masses connected by three springs. The initial position of the two masses, the spring constant of the three springs, the damping coefficient for each mass, and the driving force and driving force... Platforms: Mac

The Ejs Anisotropic Oscillator model displays the dynamics of a mass connected to two opposing springs. The simulation displays the motion of the mass as well as the trajectory plot. The initial position of the mass can be changed by dragging. The unstretched lengths of the springs can changed as... Platforms: Mac
