Delta Sigma Theta Merchandise

cross platform OpenGL visualizer to teach Delta3 robot concepts. Includes Arduino code for building your own Delta3

If no delta is specified, the default block for that module will be displayed.InstallationUnpack in your modules folder (usually /sites/all/modules/) and enable under Administer > Site Building > Modules. Requirements: - Drupal 5.x

Simple modification to add the item count and merchandise total to your header.Updated to work with STS PLUSThis is just a little usercode to allow you to use this contribution in your STS layout.Add this to your includes/modules/sts_inc/sts_user_code.php file, before the ?> at the end of the...

EZFFT(T,U) plots the power spectrum of the signal U(T) , where T is a 'time' and U is a real signal (T can be considered as a space coordinate as well). If T is a scalar, then it is interpreted as the 'sampling time' of the signal U. If T is a vector, then it is interpreted as the 'time' itself....

This program operates as a signal spectrum analyzer and a distortion meter at the same time. It can accept any numerical data representing few cycles of a signal. The data do not need to be equally separated. At least ten data points per cycle are needed. Higher number of data points will of...

[MU, SIGMA, D] = TRUNCLOGNORMEST(DATA) returns the estimated parameters of the lognormal distribution, with unknown left truncation, using the sample data of percent of observations greater than observed quantities.DATA is assumed to be nx2 where the first column is a set of known values, and the...

A few days ago I was in need of uniformly random points generation on the surface of sphere. I suddenly discovered that common parametrization with 2 angles is useless, it gathers too many points in the poles. At MathWorld you can find the complete demonstration, here the main lines:To pick a...

This function segments (clusters) an image into object classes, and estimates and corrects for slow varying illumination artifacts. Estimates and corrects for bias field in 3D MRI, streak artifacts in CT, and illumination artifacts in color photos.It's an implementation of the paper of M.N. Ahmed...

There are two components in this group.1. Hohmann Transfer Example: This simulation starts with a craft/satellite in low earth orbit. A Hohmann Transfer is initiated to a 'random' destination altitude. This includes the delta V to move to a higher orbit, and then circularize the orbit once the...

This code optimises the parameters for the term structure of volatility (TSOV) applied to historical forward curves - see discussion in Harris in reference 1 below. TSOVs avaible are: TermType - 1 = sigma = A exp (-CT) - 2 = sigma = A exp (-CT) + D - 3 = sigma = (A + BT) exp (-CT) + DRequired...

I was trying out modifications of the LMS algorithm so that it will converge faster and the mean square error will also be smaller. Getting to one of the drawbacks of LMS, that it has only one controllable parameter "mu", the selection of whose value will be the most critical from design point of...

This will perform the same function as Matlab built-in function ATAN2 butsafely guarded against erroneous results when the inputs are very small (near to a machine zero).Due to the round off errors in the numerical calculations, the twoinputs to ATAN2, Y and X, had better be thought as x=x_exact...

Conversion routines to take a surface (a function z of (x,y) or (theta,r)) and convert this into a solid; much as meshz does, but a little more useful for outputting as an STL for frabrication in a 3D printer. There are two cases, one in Cartesian co-ordinates, and the other in polar...
