Spiral Perm Rods

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...

Turn Metes and Bounds data into a plot map. - Calculates Square Feet, Acreage and Hectares. - Easily enter measurements in rods, chains, meters, yards, inches, fathoms, hands, spans or furlongs. - Can auto-close a plot drawing if the final plot segment is missing. Or enter '? to have the...

Raw MRI data are generated analytically from k-space coordinates using the (continuous) Shepp and Logan head phantom function. K -space coordinates are typically entered as 2D matrices (frequency and phase encodes).This tool is ideal for testing reconstruction of non-linear k-space trajectory MRI...

pyanpha is a shell-based program, which applies the multi-wavelength anomalous diffraction technique to Surface Diffraction. It enables one to calculate the phases of the structure factors of crystal truncation rods when anomalous scatterers are present in the thin film. Functionality extends to...

Rotoroid's driving is a popular entertainment of natives of one of the remote systems. This unusual means movement is concluded in the strong case and supplied by the tiny jet engine. The main feature of the rotoroid consists that it does not have internally steering. The pilot operates, speaking...

The Ejs Two Falling Rods model displays the dynamics of two rods which are dropped on a smooth table. In one case the end point on the table slides without friction, while in the other case it rotates about a pivot point. The simulation allows computing fall times and trajectories. The initial...

Apply the Droste Effect to an image using a GUI or function call.The Droste Effect is when an image recursively includes itself. The basic method is to insert a scaled copy of the image, but more interesting results can be achieved via conformal mapping.The GUI can load an image, set a...

LSD Spiral is a program that rotates a spiral on the screen. This program is used to simulate some of the psychedelic effects one may have during a hallucinogen trip. Look into the center of the spinning spiral for about 30 seconds and then look around you. Your brains got used to the lines...

The Falling U-Shaped Chain model simulates the dynamics of a discrete falling chain with total length L and n links. Each link is acted on by the force of gravity mg and by the link-link interaction. A freely falling object is released near the last link for comparison. The surprise is that the...

InfoPad is an application designed to store short notes. It is based on the concept of a spiral notebook, however it is searchable and expandable. I first designed InfoPad because I always had to note down little pieces of information, and ended up usually writing them on post-it notes and...

Galaxy Rotation with Dark Matter Model The Galaxy Rotation with Dark Mater model shows that the actual rotation of spiral galaxies cannot be accounted for by visible matter alone. Newtonian dynamics allows us to compute the amount of additional matter, that we call "dark", needed to compute...
