With this freeware MD5 hash values (checksums) of files can be created and compared. Because the hash function is determined by a file of any size, a fixed-length checksum. This cross-or checksum is similar to a fingerprint for each file, and almost unique. Thus, files can be compared without... Platforms: Windows

This screensaver is for those who have an eye for elegant lines of an auto body, those who admire speed and might of an engine, for whom the beauty of a car is compared to the beauty of a living being. Platforms: Windows

Windows Server 2003 is well known for its superior speed, stability, and security when compared to Windows XP.This fact is proven by Microsoft’s use of the Windows Server 2003 kernel in both Windows x64 Edition and the upcoming Windows Vista. Given this fact, it’s no wonder that many... Platforms: Windows

JDiff is a Javadoc doclet which emits an HTML report of all the packages, classes, methods, and so on, which are different (the 'diff' part) when two Java APIs are compared. Great for reporting what has changed between two releases of your product. Platforms: Windows, Mac, Linux

This project is an attempt to provide a product importer for magento that can handle several thousands of products at a reasonable pace compared to magento dataflow. it may evolve to a dataflow alternative as new features are implemented. Platforms: Windows, Mac, Linux

This script does two actions: emits a log line only if the log message was different compared to previous message and generates a log line at least every n seconds so that user knows the system is working and has not hanged. Platforms: Windows, Mac, *nix, Python, BSD Solaris

There is no change in functionality compared to the Drupal 6 core feature.InstallationUnpack in your modules folder (usually /sites/all/modules/) and enable under Administer > Site Building > Modules. Requirements: - Drupal 5.x Platforms: Windows, Mac, *nix, PHP, BSD Solaris

Getting min/max in a sequence script allows you to find the min/max value in a sequence as compared to a reference. Platforms: Windows, Mac, *nix, Python, BSD Solaris

This script simulates QPSK or 4-QAM modulation scheme in Rayleigh channel and compares it to theoretical limits.QPSK gives 3dB SNR degradation when compared to BPSK but twice as much throughput.I hope this will be helpful for students of wireless communication. Platforms: Matlab

This article consists of a brief discussion of the energy density over time or frequency that is obtained with the wavelet transform. Also an efficient algorithm is suggested to calculate the continuous transform with the Morlet wavelet. The energy values of the Wavelet transform are compared... Platforms: Matlab

This function localizes a single source from a frame of data received at the microphones. It uses the Steered Response Power with the PHAse Transform (SRP-PHAT) as the functional. The true source location will have the maximum SRP-PHAT value. Stochastic Region Contraction (SRC) is used as the... Platforms: Matlab

A uniform random number generator is used to generate the binary information sequence from the binary data source. The sequence of d-de?0d-deOaos and d-de?1d-deOaos is mapped into sequence of +E and d-deOCtEwhere E represents the signal energy. E may be normalized to unityThe Gaussian noise... Platforms: Matlab

This paper walks you through the process of profiling code running on a Texas Instruments DM6437 DSP. To demonstrate the process we profiled many common DSP algorithms including Auto-Correlation, the Dot Product, the FFT, an FIR filter, an IIR Filter, a Matrix Multiply, and an LMS Filter. These...

BPSK SYSTEM SIMULATIONWe simulate the generation of random variables r0 and r1, which constitutes the input to detector. We begin by generating a binary sequence of 0?s and 1?s that occur with equal probability and are mutually (statistically) independent. For this, we use a Random number... Platforms: Matlab

This GUI program simulates Voigt spectral lineshape and absorption spectrum from HiTRAN output file. The Voigt spectral lineshape is simulated from the convolution of Guassian and Lorentzian lineshape numerically. Absorption spectrum is calculated consequently and can be compared with...

The built-in legendre() calculates the Legendre polynomials calculated ALL the orders for a given degree. If you only need a given order, this is a waste of memory and computing time (especially for large blocks of data). The function legendreP(l,m,x) is a drop-in substitute for legendre(l,x),...

The toolbox can import spectra acquired on spectroradiometers manufactured by Analytical Spectral Devices (ASD), Spectra Vista Corporation (SVC), Ocean Optics and the Field Spectroscopy Facility (FSF). It can post process spectra to calculate spectral reflectance, radiance and irradiance. It also... Platforms: Matlab

This function is a substitute for the standard versions of quiver and quiverm available using a vanilla release of matlab. This version assumes a 2D vector field is being plotted using a gridded flow field from a numerical model. It is primarily intended for Earth System Model analysis.The... Platforms: Matlab
