A Kirchhoff elliptic vortex is a 2D elliptical region (or d-deDUpatchd-deDt) of uniform vorticity embedded in an inviscid, incompressible and irrotational fluid. G. Kirchhoff showed that these are exact solutions to the nonlinear Euler equations in 1876.Subsequently, A. E. H. Love analyzed the... Platforms: Matlab

This function solves the "forward geodesic problem," which is to compute the endpoint of a geodesic (shortest-distance) path on the ellipsoidal earth, given the start point, a path length, and a starting azimuth.In response to a user request, this function numerically inverts the previously...

Final Cut Pro X , with its easy-to-use, freeform timeline, is truly revolutionary. However, with new ideas come new challenges and tools. This in-depth editing tutorial by expert editor Michael Wohl, dives beneath the ???*NsMagnetic???*N? timeline???*a*?s surface to show you FCP X???*a*?s many... Platforms: Mac

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 FIT-MART Launcher package is a self-contained file for simulating systems of interacting quantum magnetic moments ("spins"). The interactions are modeled using the Heisenberg model, calculations are carried out by numerically diagonalizing the matrix representation of the Heisenberg... Platforms: Mac

Landscape photographers typically wish to plan their shoots around the times of sunset/sunrise or twilight, or alternatively when the moon is in a particular place in a particular phase. While times of sunrise etc. are readily available on various sites on the internet (direction of sunrise etc.... Platforms: Mac

Time::CTime is a Perl module with format times ala POSIX asctime. SYNOPSIS use Time::CTime print ctime(time); print asctime(localtime(time)); print strftime(template, localtime(time)); strftime conversions %% PERCENT %a day of the week abbr %A day of the week %b month abbr %B month %c ctime...

This is a simple module for doing very very simple quick tests on a database, primarily designed to test if a row exists with the correct details in a table or not. For more advanced testing (joins, etc) it's probably easier for you to roll your own tests by hand than use this module. Exports... Platforms: *nix
