phpChart class package provides a PHP class package derived and hacked from advGraph to generate charts in Flash4 SWF format. The Ming PHP extension to SWF is used in this class package.

Simple Browser Proxy was derived from a wish for an easy to use proxy that didn't require any installation or odd programs to be running. Thus, SBP isn't meant to be used by someone who wants/requires total anoniminity. For example, images are not fetched by SBP; rather, the path to them is...

UTC time (universal time convention) is used in ANSI-C standard for defining time. This is measured in seconds since 1970, at the Prime Meridian.The UTC2Datenum_array function takes a M x 1 array of UTC time values and converts it to a M x 1 array of Matlab serial Time values.This code is derived...

LU Decomposition is applied to a sparse banded matrix. We show how fill-ins can make solution by elimination not manageable. The same matrix is used to solve the Poiseuille flow problem in a rectangular channel using the finite differences approach. The result obtained using this numerical...

CORNER works by the following step:1. Apply the Canny edge detector to the grey level image and obtain a binary edge-map.2. Extract the edge contours from the edge-map, fill the gaps in the contours.3. Compute curvature at a low scale for each contour to retain all true corners.All of the...

We compare computed temperature distributions using both pdepe and analytical solutions for different geometries (slab, cylinder and sphere). Solids are kept initially at uniform temperature. For t>0, the boundary surface is kept at constant temperature. Results show excellent agreement....

The code performs a minimax optimization on a Simulinkk model consisting of empirically-derived human operator informatic parameters and real world nonlinearities. The tool finds solutions for the design of an input device (design variables are control gains) that interfaces human operators with...

Analysis of Means (ANOM) is a statistical procedure for troubleshooting industrial processes and analyzing the results of experimental designs with factors at fixed levels. ANOM is an alternative to ANOVA for a fixed effects model. Unlike ANOVA only determines if there is a significant difference...

This simple function tests the null hypothesis that two variables are equally linearly correlated with a third variable when all three sets of observations were derived from the same "individuals" (i.e., a repeated measures/paired observations design). The test uses a t-distribution and was taken...

An empirically derived routine for bringing out the thread detail in canvases. An example x-ray image (histogram equalized raw.tif) illustrates the problem of manually counting canvas threads for painting forensics. Paint, cracks, and shadows make it difficult to easily discern the cross-hatched...
