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
RADIATION HEAT TRANSFER- SHAPE FACTOR CALCULATION (MECHANICAL ENGINEERING)
The file, sfactor.m ; (example) xxx = sfactor(a). calculates shape factor between two flat surfaces with arbitrary orientation and location.
Used on cellular phones to filter out background noise. Measure the signal to noise ratio of an audio input in realtime. Pass speech but give silence where the input is noise (hiss, snap crackle and pop).
Includes a tutorial on how...
Consider a situation in which predicted probabilities of a given event of interest are estimated using two models that share all risk factors, except for one new marker. Let us categorize the predicted probabilities based on these two models...

Mortgage calculator. GUI allows inputs of mortgage, interest rate, and amortization period. It calculate monthly payments, total payments and plots curves of interest payments and principal payments for each month. To bring up the GUI...
If the current axes have been rotated away from the X-Y view, this function will calculate the angles of the current x, y and z axes with respect to horizontal. These angles are used to rotate the current x, y and z axes labels to align them with...
This include a MEX-DLL file which is an implementation of R L Siddon's refined method by Jacob for the calculation of ray path integral in PET/CT system image reconstruction. This is based on Line Intersection Length model to calculate probability...
The files perform numerical summation to obtain potential, electric field, and multipolar dielectrophoretic forces information for a configuration having semi-infinite top electrode and infinite bottom electrode.
The zip file contains...
We calculate the number of photon with two methods. We dertermine the differnce of luminance for two (or many ) wavelength.
We can find the error with the temperature and the wavelength for different acquisition time and many geometry.
i download one matlab file from here to calculate the modes in laser, Laguerre-Gauss modes but it was not working properly. So i wrote my own function. It is pretty simple function, i hope it is efficient as well. i used it and post the result i got.
Functions to calculate Clebsch-Gordan, Wigner 3-j, Wigner 6-j, and Wigner 9-j coefficients, frequently used in quantum mechanical calculations involving angular momentum.
There are three M-files: 1. third.m, calculates the third-order moment for a time series 2. aaft.m, calculates the Amplitude Adjusted Fourier Transform (for more details see: D. Kugiumtzis, Surrogate data test for nonlinearity including...
plotAverage adds an average line into plotted data.
By default, plotAverage - calculates the average along y (for given or estimated points along x) - plots errorbars with the standard error of the mean - discards...
This PHP script provides a very easy way to embed dynamically generated vertical bar graphs and charts into PHP applications and HTML web pages.
The graphing software is very easy to use and it's perfectly possible to add professional...
