It is an application focused on the ontology modeling ot the experimental factors in ArrayExpress.The application is used also in the constructing of mappings to multiple existing domain specific ontologies, such as Disease Ontology. Platforms: Windows, Mac, *nix, Perl, BSD Solaris

This code takes an expression for a normalized AF in spherical coordinates and creates a 3D plot in cartesian coordinates. Examples are specific to Antenna Theory and Design (2nd Ed) by Stutzman and Thiele. Platforms: Matlab

The function implement the 2D dyadic(Paley) ordered fast in-place Walsh-Hadamard transform, which can be used in signal processing, pattern recognition and Genetic alogorithms. This algorithm uses a Cooley-Tukey type signal flow graph and is implemented in N log2 Nadditions and subtractions. Data... Platforms: Matlab

This ZIP file contains function that provide simulation of the following models:- Free space loss calculation- Reflection quantization in generic surfaces for vertical and horizontal polarizations- Plane Earth loss calculations, and- Calculation of the Divergence factor in spherical Earth Platforms: Matlab

If you pass in 2 vectors it returns the unnormalized distance between the vectors, the accumulated distance between them, the length of the warping path (the normalizing factor), the warping path points and both warped input vectors.You can plot the results too if select the pflag=1 Platforms: Matlab

The file calculates and plots FM noise sidebands for a carrier. It also does sinusoidal modulation. This simple way of adding noise to a carrier is useful for simulation of PLLs. It turns out, though, that the mean of the randn function is not as close to zero as it could be, and this causes the... Platforms: Matlab

This function gives the decimation matrix which after post mulitpling it with the given signal gives the downsampled version of the original signal...D = decimmtx(x,N)decimates the given signal by a factor of N.[D,y] = decimmtx(x,N)gives D as well as the decimated signal y Platforms: Matlab

The signals presented here can be used in demonstrating how the signal varies when the operation is made on either independent variable or dependent variable. The parameters can be varied to have a feel of the variation.Example(1): rect(1,2) plots the rectangular signal of amplitude 1 and a width... Platforms: Matlab

The main program is Main_sound_and_vibs.m. Up to 100 metrics are for each of sound, hand arm vibrations, whole body vibrations, and motion sickness. Main_sound_and_vibs calls the primary depedent function"Continuous_Sound_and_Vibrations_Analysis" which contains the switch statement controlling... Platforms: Matlab

ScaleTime - fast linear matrix interpolationI have recorded timeseries of e.g. size [100'000 x 10] and cut out chunks of about 100 frames according to some events and normalize them to exactly 100 frames.For this task, the direct approach with Matlab's INTERP1 works, but it is slow:... Platforms: Matlab

You only have to run main01.m, is easy to change the composition and operating conditions. If you want to add new components just add the critical propeties and acentric factor. Also is possible to use binary interaction parameters differents to zero. Platforms: Matlab

The model simulates a three phase Sinusoidal PWM rectifier. Applied Voltage, switching frequency and sampling factor can be changed from the model properties block. Platforms: Matlab

View factor is a MATLAB function that uses the CDIF (contour double integral formula) to calculates view factors between planar surfaces(polygons), no matter what are the shape and the orientation of the two figures.All you need to enter is the coordinates of the vertices that define the outlines...

We use the SRK equation of state to compute the correction factor due to gas-phase nonideality as a result of the high pressure applied in the ammonia synthesis. We also compute the extent of reaction. Plots of these two quantities versus pressure for temperature equal to 800K are presented. The... Platforms: Matlab

The absorption coefficient can be obtained empirically by using Thorp's formula.Thie formula that used in the code is generally valid for the frequencies above a few hundred hz.The absorption coefficient is used to find the absorption loss part of the path loss in underwater wirelss...
