dark software

Dark Solar System by Icon Empire

Dark Solar System is a new 3d screensaver for Windows. This screensaver shows all planets of our solar system, uncluding Saturn''s rings. It makes you able to know about dark matter and dark energy in our planet system. At the beginning of March, 2006 the satellite of China National Space Administration, DARKSTAR started operations, observing in neutrino the solar corona. We have placed this new information into our screensaver.

curve fitting software

CurvFit by Optimal Designs Enterprise

CurvFit (tm) is a curve fitting program 4 Windows. 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 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*.?
