This is an implementation of the calculation of STC value according to ASTM E 413-04. Classification for Rating Sound Insulation.
Input the transmission loss in one third octave bands (dB) and enter the frequency bands and the program will calculate the STC value and produce a graph.
The center frequencies do not have to be exact as the program matches them to the reference contour and applies a tolerance
NGP Campaign Features is a set of feature modules that will create content types, default views, and panels for common political campaign site needs. Currently included are events, issues, media center, video gallery, and home page features.
The function circumcircle takes input as the coordinates of the three vertices of a triangle and compute the circum center and circum radius by using the formula in terms of the length of sides and area of triangle and plot the circumcircle.
This simple module allows you to easily integrate Help Center Live (FREE from http://www.helpcenterlive.com) into your Joomla site.
function y = getiq(x,freq)
this takes in the frequencies X that were received at a rate of FREQ and gives you a complex value which is I and Q - this is used when you have frequency X changing and the phase is cumulative - meaning it does not...
Digital Product Manager is a PHP script that allows PayPal IPN integration in order to sell files, including an admin center that tracks and can edit all products and prices. It masks product urls to protect your files.
function W = euklid_W(ws,d,n)
function W = euklid_invW(ws,d,n)
PURPOSE: create an (inverse) euklidean distance spatial weight matrix
(n x m 'moving-window' style matrix with distance to center cell
Crop upper/lower half-, and whole-circle sections in the center of a colour image. Optional move of cropped section inside the image and away from center.
This is an approximation of the Voigt function within the Humlicek regions 3 and 4. The approximation is one given by S.M. Abrarov et. al. "High-accurace approximation of the complex probability function by
Fourier expansion of...
This function create a matrix containing a filled circle. The circle has center in points specified in vector vCenter (represented as [x y]) and radius specified by nRadius.
The A8Dropzone simplifies all file uploads and provides the following key features:
* Upload by Drag-&-Drop of one or even several files onto the A8Dropzone
* Upload by copying files in File Explorer and clicking on the...
The enclosed files provide a nonlinear algorithm for controlling dynamical systems, particularly in regimes where linear control methods often fail, such as the targeting of states that are distant in phase space from the system dynamics (e.g., a...
You start with eight cubes around a center hole. Each cube is white on the top and black on the bottom. Roll cubes in the start position but with the white faces on bottom. Click on a cube to roll it. It is possible to win in 36 moves. This game...
It can automatically resize images to fill browser windows and keep aspect ratio for the displayed image.
It can cycle images/backgrounds via slideshow with transitions and preloading. Navigation controls allow for pause/play and...
Transforms a 24x24 pixel patch (576-dimensional) to 132-dimensional representation by averaging pixels far away from the center (i.e. fovea). There is code for both directions of the transform.
PHP Call Center is a web-based application used to keep track of a company's incoming phone calls.
It is unlike other call loggers in that it is not based on "tickets" as those systems are often confusing and cumbersome to use.
This wordpress widget displays a list of the blog's participants, with a link to their profile, and the number of posts and comments they have contributed.

Plots triples ( t, real(z(t)), imag(z(t)) ), a shiskebob of complex numbers. For visual context, each complex number is a dot on its own gray constant-amplitude envelope circle with a blue radius from the center axis.
Fits an ellipsoid into a 3D set of points, allows some constraints, like orientation constraint and equal radii constraint. E.g., you can use it to fit a rugby ball, or a sphere. 'help ellipsoid_fit' says it all. Returns both the algebraic...
This plugin is made for developers.
It creates a function called thumbGen() that allows to show any image in the specified size. Additionally you can specify the way it crops the image and you can generate it in grayscale.
