Benefits Of A Relational Database

S3DB - Simple Sloppy Semantic Database - is a PHP / mySQL,postgreSQL implementation of a local database infrastructure with a semantic architecture. The philosophy of its development is data driven. Platforms: Windows, Mac, Linux

SmallSQL is a 100% pure Java DBMS, a relational database for Java desktop applications. It has a JDBC 3.0 interface and offering many ANSI SQL 92 and ANSI SQL 99 features. It is very small and fast Java library. It does not have a network interface. Platforms: Windows, Mac, Linux

This script uses string.index(sub) function which returns a list of indices of ALL occurances of a substring in the string. Platforms: Windows, Mac, *nix, Python, BSD Solaris

This script allows you to replace a portion of a string at a given position. Platforms: Windows, Mac, *nix, Python, BSD Solaris

When working with text, it may be necessary to change the indentation level of a block. This code will take a multiline string and add or remove leading spaces to each line so that the indentation level of the block matches some absolute number of spaces. Platforms: Windows, Mac, *nix, Python, BSD Solaris

This script uses the Internet Protocol Helper functions on Win32 and helps you to find the MAC adress of a remote computer. Platforms: Windows, Python,

This scripts shows you how to obtain the name of a method or a function from within the running method/function. Platforms: Windows, Mac, *nix, Python, BSD Solaris

This simple code calculates the convex hull of a set of 2D points and generates EPS files to visualise them. Platforms: Windows, Mac, *nix, Python, BSD Solaris

This script shows a way to generate a list of all strings (in this case, string=list of symbols) of a given alphabet having a specified length by using list comprehensions. Strings (not the 'string' type) are frequently used in computer science; for example numbers are encoded as strings of... Platforms: Windows, Mac, *nix, Python, BSD Solaris

602SQL Open Server is a relational database management system for MS Windows and Linux based on the client-server model. The system provides ODBC, PHP and SDBC (for OpenOffice.org integration) connectivity, along with a graphical development environment and SQL debugger. Key Features: - Open... Platforms: Windows, Mac, *nix, C/C++, BSD Solaris

3D Array Factor of a 4x4 planar array antenna calculated using general formulas and then plotted in 3D format."AB" shows the excitation amplitude of the elements and "AB_phase" shows their phases.Elements are placed on the x and y axis and element factor is ignored. The code can easily be... Platforms: Matlab

Finding the Fourier transform of a rectangular pulse..filtering the spectrum and regenerating the signal usingthe filtered spectrum is done...at the end Rayleigh theorem is proved by showing that the energy content of both time domain and frequency domain signals are equal..your comments are... Platforms: Matlab

It is very fast and simple file to display histogram of a 3D imageimhist3(I,n) n is the number of bins in the histogramimhist3(X,map) X isindexed 3D image and map is colormap map Platforms: Matlab

This demo shows how to use MATLAB, Optimization Toolbox, and Genetic Algorithm and Direct Search Toolbox to optimize the design of a double wishbone suspension system.Note: You will need to have the following products installed in order to run this demo: MATLAB, Simulink, Optimization Toolbox,... Platforms: Matlab

n the bottom of a Stefan tube there is a quiescent liquid with a mixture of acetone (component 1) and methanol (component 2). Vapor that evaporates from this pool of liquid diffuses to the top of the tube. Air (component 3) keeps the mole fractions of components 1 and 2 equal to zero. This... Platforms: Matlab

This model simulates the position control of a DC motor. Parameters can be changed from the model properties tag. Platforms: Matlab

The code computes the velocity profile for the vertical laminar flow of a Bingham fluid down a wall. As expected the profile is flat near the surface of the liquid film. In fact, we have a zero velocity gradient only when the shear stress is large enough (superior to tau0). This behaviour is... Platforms: Matlab

Equations of motions of a Cessna are modelled in this matlab GUI. Cessna levels of to a steady level flight at 10.5 kms. Four plots show (a) Alt Vs Time. (b) Alt Vs G. (c) Vel Vs Tim. (d) Flight path angle Vs Time. Other plots like Range, Ceiling, Flight Path Angle can be obtained using the GUI... Platforms: Matlab

The standard problem of a Two Link Manipulator is developed both kinematically and dynamically. It is then controlled to trace a rotated ellipse. The non-linear terms (like gravity/inertia etc.) are exclusively canceled out in varying degrees and the performance studied.This file was created as a... Platforms: Matlab

The velocity and shear stress versus radial position are obtained for the laminar flow of a power-law fluid in a pipe. Pipe radius and applied pressure gradients can be set by the user. If you choose a power-law exponent, n, equal to 1 then a Newtonian fluid is recovered. Dilatant and... Platforms: Matlab
