Delta Phi Epsilon

Simple V converts FHX files created by the Delta V programming laguage into easily readable charts. Allows reviewing of code without havaing the Delta V ide installed.

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

[psi gopt] = dfdesign_w_lmi(phi, w, d, n);DFDESIGN_W_LMI computes the H-infinity optimal inverse FIR filter of phi(z).The resulting filter minimizes the H-infinity norm of the error system E_w(z) = [z^(-d) - psi(z)phi(z)]w(z).The LMI method based on KYP lemma is used in this function.[INPUT]phi:...

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...

Phi = keplerSTM(x0,dt,mu) will return the state transition matrix Phi for a set of objects described by initial positions and velocities (x0) with gravitational parameters mu, propogated along Keplerian orbits for time dt. The positions and velocities at time dt is then given by Phi*x0. x0 must...

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...

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 simulation was generated to compare the MASH 111 SDM with other types of SDMs. This file outputs the average fraction to compare with the one specified as an input, and plots the noise. The Multi-feedback SDM which this was compared to is submitted in a separate posting.

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...
