I have helped thousands of teacher candidates pass their CSET exam over the last 10+ years and I have found one thing nearly all these people have in common, a positive attitude. People who are happy and positive have a pass rate that is nearly three times that of people who are stressed out,... Platforms: Windows

A program to help to the teacher to control the pupil's assistence to classroom. It makes statistics and backups. It's developed using php, so you can use in a windows or unix environment. Platforms: Windows, Mac, *nix, PHP, BSD Solaris

[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:...

Only in very simple situations can we describe the correlation between two time series as a single number. Often it varies both as a function of time, and of wavelength. Datasets may be uncorrelated on short timescales due to noise, but strongly correlated on larger wavelengths (eg annual).This... Platforms: Matlab

Dilates a time series input and resizes it to the orignal sample lengthinput. If a matrix is input, dilation is done along columns. % The up/downsampling is done via resample.m, so low-pass filtering of theup/downsampling is automatically implemented. An anti-alaising, lowpassfilter is applied to... Platforms: Matlab

Uses Simulink to compute Vapor-Liquid Equilibrium diagrams for ethanol-water binary mixture. To compute activity coefficients, program uses Van-Laar Model. This mixture presents a positive azeotrope. Platforms: Matlab

This script is capable of solving a convex quadratic programming problem by Wolf's method. For the convergence of the algorithm it is necessary that either Hessian of the objective function be positive definite or positive semidefinite Hessian with linear term zero. For theory of Wolf method and... Platforms: Matlab

A command-line peak fitting program for time-series signals, written as a self-contained Matlab function in a single m-file. Uses an non-linear optimization algorithm to decompose a complex, overlapping-peak signal into its component parts. The objective is to determine whether your signal can be... Platforms: Matlab

The model simulates three phase inverter with symmetric PWM modulation in which reference is sampled at the positive peak of the carrier and is held constant till the next positive peak of the carrier appears. The model demonstrates symmetric regular sampling at positive peaks of carrier and... Platforms: Matlab

This function calculate the performance, based on Bayes theorem, of a clinical test. The input is based on a 2x2 matrix (true positive, false positives; false negative, true negatives).The Outputs are:- Prevalence of disease- Test Sensibility with 95% confidence interval- Test Specificity with...

How do bacteria find their way to the food ? many biological systems use the chemo-taxis algorithm to improve their conditions and hence, their chance to survive. Chemo-taxis in general refers to movement influenced by chemical properties of the medium. In this model, we have a group of... Platforms: Matlab

The adiabatic catalyst problem arises in the field of chemical engineering. If chemical reaction kinetics within a solid catalyst body are influenced by mass transfer multiple steady states are possible for a certain range of the governing parameters: arrhenius number, prater number and thiele...
