Mondrian is an OLAP server written in Java. It enables you to interactively analyze very large datasets stored in SQL databases without writing SQL.Online Analytical Processing (OLAP) means analysing large quantities of data in real-time. Unlike Online Transaction Processing (OLTP), where typical... Platforms: Windows, Mac, *nix, Java, BSD Solaris

Wuhkag is an open-source Web application written in PHP for evaluating Web sites accessibility and publishing an HTML accessibility policy. Wuhkag currently supports W3C WCAG 1.0 and requires PHP4. The actual name derives from the short name of the guidelines for Web content accessibility (WCAG),... Platforms: Windows, Mac, *nix, PHP, BSD Solaris

PBOS is a web-based book-annotation system that lets authors add books to read, and readers markup the books with notes, links, bookmarks, and other annotations. It lets readers share their annotations or keep them private. Written in php w/some perl. PBOS (Processed Book Operating System, or... Platforms: Windows, Mac, *nix, PHP, BSD Solaris

This package is a loosely defined collection of tools for application of Python in a laboratory environment. It consists of pure python protocol drivers for various useful devices, including: National Instrument DSTP protocol to interface Python to LabVIEW VXI-11 protocol, to allow python to talk...

Professor Jim Wilkes provides representative values of the volumetric flow rate versus the applied pressure gradient for horizontal flow in a pipe [1]. The pipe radius is equal to 0.01 m. We use these representative values, in conjunction with the analytical expression of the volumetric flow... Platforms: Matlab

The function LMFsolve.m serves for finding optimal solution of an overdetermined system of nonlinear equations in the least-squares sense. The standard Levenberg- Marquardt algorithm was modified by Fletcher and coded in FORTRAN many years ago. LMFsolve is its essentially shortened version... Platforms: Matlab

The inversion of Laplace transforms is performed using two methods: (1) the Zakian method and (2) the Fourier series approximation. Results are in agreement with analytical solutions. The Zakian method presents problems for transcendental functions. The Fourier series gives better results when... Platforms: Matlab

A collection of m-files aimed at learning and teaching about the principles of diffraction gratings. Some of these show a cross section of the geometry of a diffraction grating, a common illustration in textbooks of optics, spectroscopy, and analytical chemistry.Sliders on the figures allow...

These files introduce how Symbolic Math Toolboxd-OC?D? can be used to evaluate Nelson Siegel and Svensson models, which are 2 widely used techniques for modeling yield data. We demonstrate how you can define the models in the MuPAD notebook interface and perform some basic analysis and... Platforms: Matlab

If you dip a straw in a cup of water and hold your finger over the top, you can then pull the straw out and remove the amount** contained in the straw.Obviously it would take an infinite number of dips to empty the cup completely, but did you ever wonder how many times would you have to repeat...

The Levenberg-Marquardt Fitting of Nuclear Decay Model demonstrates how EJS can be used to fit experimental data. In this simulation, nuclear decay data are used to provide a simple example, but this same process can be applied to any type of data. The sum of squared deviations is minimized but...

The Ejs Phase Space Plotter model displays the dynamics of an ensemble of pendula or simple harmonic oscillators in phase space (velocity versus position). Friction is initially set to zero but can be changed via a textbox as can the number of elements in the ensemble. For the pendulum ensemble,... Platforms: Mac

GC-EAD is coupled gas chromatography - electroantennographic detection. It is an analytical procedure that permits the rapid identification of compounds in complex mixtures that stimulate the olfactory sensilla of an insect. In other words, it can tell you what specific chemicals an insect can... Platforms: Mac
