Software Listing: Diffusion

GPU version of the anisostropic diffusion filter by Perona and Malik, created using mex and CUDA. It's my first attempt to write a GPU-enabled program. Any suggestion will be appreciated..

DIFFUSION_DISTANCE calculate the diffusion distance between matrices dist = diffusion_distance(im1, im2, [sig, dim], threshold, pad_type]) [dist, iter] = diffusion_distance(im1, im2) compute the diffusion distance between im1 and im2 (histograms). Optionally returns the number of iterations. This number will be limited by the size of the histograms, and the threshold value, which can be set manually, or will take the value 1e-4. The padding method used by the filtering stages can be set using the 4th argument, and defaults to circular. For available options, see help imfilter.

Convective Adsorption - Desorption software is used to study water diffusion processes with known experimental data, for the following geometries: infinite slab, infinite cylinder, sphere, finite cylinder and parallelepiped. The software makes possible the determination of the diffusivity 'D' and the convective mass transfer coefficient 'h' through optimization.
Keywords: adsorption, soaking, desorption, drying, kinetics, diffusion, diffusivity, Biot's number, convective mass transfer coefficient, thin layer, partial differential equation, infinite slab, infinite cylinder, sphere, finite cylinder, parallelepiped, transport phenomena, water diffusion, optimization, curve fitting, boundary condition of the third kind, Cauchy.

A cellular automaton consists of:

(a) A structure of cells, such as the squares on a chess board.
(b) A set of values or 'states' such that each cell is associated with a particular state.
(c) A set of rules describing how one state of the system (a particular configuration of cells in specific states) is to be transformed or converted to another state of the system.

This is software for exploring five cellular automata, as follows:

1. An extended version of Conway's Life, called q-state Life.

2. A simulation of the Belousov-Zhabotinsky chemical reaction in which, beginning from a random state of the system, spirals and curlicues 'spontaneously' emerge.

This is an educational program for the field of physics
and chemistry, supported by simulations.

This program is a type of graphic simulation, which is the most
important element for educational purposes.

The program consists of nine sequences (substance classification,
molecule motion, Diffusion, Brown's motion, temperature and pressure,
ideal gas, real gas, crystal structures, etc.).

During every simulation, the capability exists to continuously change
certain parameters (temperature, volume, etc.)..

Fusion Field is a smooth diffusion reverb that sits beautifully in a mix. A clean, unobtrusive sound with a natural falloff that floats and complements the source material perfectly. Designed to imitate complex, natural spaces, it is also very easy to use. The main 'cloud' display represents the reverb in terms of time and frequency, showing all the main parameters and EQ in a natural way. The reverberation can be dampened in the upper and lower frequencies, allowing soft sibilance and a graceful, lifting air to the sound. Having very few controls does not hinder Fusion Field's usefulness. The dial ranges have been sloped to give the best sensitivity in useful regions, and the whole unit can create short snappy rooms, or vast time-suspended spaces, and anything in between.

Matlab implementation of a monodomain reaction-diffusion model in 2-D. The model equations are a variant of the Fitzhugh-Nagumo equations modified to simulate the cardiac action potential. The progression of the two normalized state variables, membrane voltage (v) and recovery (r), is computed across a 128 x 128 spatial domain and across time. This function simulates spiral waves, which are hypothesized to underlie reentrant tachycardia. The spiral waves can be initiated by two different cardiac pacing methods: (1) two-point stimulation where a point stimulus is delivered in the center of the domain followed by another point stimulus on the partially refractory wake of the first wave of excitation.

Membrane diffusion in a coupled reactor system can cause complex behaviour such as oscillations, period doubling and chaos. Here we study a simple model suggested by Deng-Harrison in 1969. The bifurcation diagram is obtained. We find good agreement with Figure 10 page 76 of the paper by Lengyel and Epstein. Reference: I. Lengyel and I. R. Epstein, Diffusion-induced instability in chemically reacting systems: Steady-state multiplicity, oscillation, and chaos, Chaos 1 (1) 69-76, 1991..

The purpose of this program is to simulate the permeation time lag in a polymer hollow fiber membrane with a dual mode sorption isotherm and the partially immobilized diffusion model. The program plot the 3D time lag with two models: 1) concentration gradient as the driving force for diffusion 2) chemical potential gradient as the driving force for diffusion. The error estimation between the hollow fiber and slab membrane was also provided. The plot is in 3D mesh against upstream pressure and curvature ratio..
