- CR-39 track profile for protons and alpha particles
- License: Shareware
- Price:


Co-authors Saed Al-Nia'emi and Mushtaq Al-Jubbori This software is a result ofnew empirical parameterization describing the protons and alpha particle track profile development against etching time and particle energy is presented. The parameterization uses MATLAB programming language, with four free fitting parameters. It is shown that this parameterization can reproduce not only track diameter and depth but also the overall track profile formed on the CR-39 by protons and alpha particles at different energies and etching times. pdf user manual is included in the Zip file

- Demonstration of Fourier transformation
- License: Freeware

These are two M-files 'fourier1' and 'fourier2' The first is designed to demonstrate how triangular, rectangular, saw tooth, half wave and full wave rectified signals can be built from superposition of a predefined no of Fourier harmonic terms. It demonstrates how increasing the number of terms included in the summation will improve the signal shape. The second file is useful for analyzing actual audio signals connected to the PC line in port of the sound card. The out put of the program is plot showing all harmonic amplitudes contained in the signal.. It can be used with a microphone, a signal generator, or with any sound pre-recorded or saved and being played on the PC.

- Fully Automatic Signal Spectrum Analyser
- License: Freeware
- Price: 0.00


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 course produce better results. The main advantage of the program is its ability to automatically detect the fundamental frequency. Any part of the spectrum within the frequency band f1-f2 can be calculated and plotted. The input to the software are the time and signal voltage arrays t,v, the frequency band limits f1 and f2 and the accuracy parameter delta. The out puts of the program are the signal plot, the spectral analysis plot, the frequencies and relative amplitudes of the ten most prominent frequency contents. The software has been...

- Langmuir probe data analysis code
- License: Freeware
- Price: 0.00


A computer code for plasma Langmuir probe analysis is presented here. The code uses a four parameters fitting method to deduce plasma properties including the ion and electron saturation currents, plasma potential, plasma electron temperature, the electron energy distribution function EEDF. Full simple instructions are given in the pdf file. No need of prior knowledge of MATLAB programming is assumed. The code is compatible with any MATLAB version. If you are working in plasma physics, please give me your feedback

- M- file for Audio spectral analysis
- License: Freeware

The file is written for MATLAB 6.5 it aquires data from the sound card . Fourier spectral power analysis one second of audio signal sample is analyzed by simply running the M-file. The frequency contents of the voice analyzed are shown of a plot. I have used this program to compare voice qualities of many music starssome proved realy as good as they claim others didn't. the property to look for on the plot is the number of peeks, the frequency spacing between peeks, their relative amplitude ratios. for good sopanos higher frequency contents has to large

- rotation
- License: Shareware
- Price:


This program performs rotation of coordinates of an (x,y) figure by any angle measured in degrees about the origin. Any set of (x,y) data will be transformed to (xx,yy) in the new rotated coordinates. Original and transformed data are plotted in blue and red respectively. The program is particularly useful when one tries to calculate the oblique profile from a particular normal profile.

- Two Dimensional Surface Fitting Program
- License: Freeware
- Price: 0.00


This program represents a further development of the standard powerful 'nlinfit' facility already in matlab. The major problem with 'nlinfit' is that it can only handle fitting of one dimensional arrays (x, y) where x is the independent variable and y is the dependent one. The program fit2 uses another program 'fitfit' where the user fitting function can be defined. This user defined function is defined in line 6 of fitfit as ff in terms of a,x,y. The input arguments to the program are 1- a which is an array representing the starting values of the free fitting parameters ( similar to that when nlinfit is used) The length of a must be equal to the number of parameters used in the user defined function to be fitted (line 6 in the M-file "fitfit" 2- x and y are each a one dimensional array representing the independent variables 3-...
