With the Harmonix PhotoShop plug-in you can create complex waveforms. The waveforms generated by Harmonix are created by mixing (or superimposing for the more technically-minded) harmonic frequencies. All features of the waveforms are automatically scaled to fit the image (or selection of course) so you will not have to reconfigure an entire wave should you decide to change the image size.

CurvFit (tm) is a curve fitting program 4 Windows 95/98. Lorentzian, Sine, Exponential and Power series are available models to match your data. A Lorentzian series is highly recommended for real data especially for multiple peaked/valleys data. CurvFit is an example of Fortran Calculus programming... ie. minutes to solve, days or years to understand solution and what it implies (e.g. wrong model, sampling rate error). See comments in EX-*.?

Logic board game, which has not analogues, will serve as a good occasion for a break in work and will ensure you interesting free time spending and rest. The purpose of game is drawing up so-called "quadros" - crossed squares which have been picked up in such a manner that of a point of crossing is a continuation of sequences in adjacent squares.

Riveting four-way action as colored pieces appear randomly along a grid and move toward the center. You must eliminate the colors before they enter the center square. If you strike a colored piece that is the same color as the center piece, that color will be eliminated. If you strike a piece of a different color, you will exchange colors with that piece and it will remain on the grid.
