An Insider View of Uploading Files using ASP is an easy to understand tutorial aimed to give the readers a brief outlook on file uploads for web applications. The author has explained the concepts in a clear format along with the individual ASP codings. You will come to know about both HTTP and FTP file uploads, their merits and demerits, the advantages of SA-FileUp, the active server component integrated with ASP over the Microsoft's 'Posting...
Show The Size Of A Directory Using ASP is an online article explaining ASP beginners and programmers to use FileSystemObject function of ASP in finding the file sizes. The author has also given some notes on the above topic along with the code...
Generation of captcha image composed of numbers without using any fonts. As such it adds more variability to symbols (because every symbol is generated using random noise). And because of this - should be more secure than known set of fonts.
Generation Of Solid Shapes Using Random Number Generator.
The Solid Shapes included are:
4) Conical Frustum
6) Pyramidal Frustum
Take it as...
Limit of stability Curve using RK for N2O
Surprisingly, I never came across the simple solution of aggregating data using accumarray. Accumarray needs indices supplied to aggregate too. Combining this with the Unique function, the user can quickly and conveniently aggregate data using any...
This function calculates radar cross section (RCS) of the scattering of a object using mie theory.
Its accuracy is tested.
Fast version of r576930 reimplemented using a list of lists instead of a node class.
A simple Towers of Hanoi demo using wxPython.
This sits with my Koch snowflake demo and Guido's
similar demo using Tk. Credit to Martin Bernreuther
This recipe take an xml file as input and output a colorized version of this file, using html or docbook (with emphasis elements and a particular role). It provides a little command line interface and it's really easy to configure your output.
The program takes the columns of an input matrix and calculates the auto and cross correlation of these columns using an fft method. The result is very similar to the xcorr function. This method could be used to evaluate the cross correlation of...

This function calculates the variance of a population using only the means, variances and number of observations of its subpopulations.
This means you do not need to keep all individual observations in each subpopulation to later find...
This is a simple functino to import a series of dicom files using the dicomread function.
Please go through the comments in the code. It is quite a simple one but might be handy to use it quickly.
I wanted to...
Control system for DC machine with current back-propagation and two levels of excitation is using in wide area of applications.
It developed for modeling of robustness in power circuit of electrical engine. The action of electrical engine...
This script I use to improve the contrast of images by using imadjust command. The only problem is limited number of files (about 40 - 50) which can be processed at once.
The code is:
Represent a wavefront as a sum of Zernike polynomials using a matrix inversion.
This function attempts to solve the a_i's in equation, phi(rho,theta) = SUM(a_i * Z_i(rho,theta), i=1 to M),
where the Z_i(rho,theta)'s are the Zernike...
