Find best Spectral Estimation Method for a Power Spectral Density plot. A menu of 10+ spectral estimators from Steve Kay"s textbook, Modern Spectral Estimation, 1988, is available to choose from. The results differ dramatically from one estimator to another. Plus, varying input parameter and/or number of points may provide discrepancies.

ODEcalc for Windows: An Ordinary Differential Equation (ODE) Calculator! State your equation and boundary or initial value conditions and it solves your problem. Plots solution, y, and derivative, ydot, versus x.
Solves most Boundary Value Problems (BVP) and Initial Value Problems (IVP) for Nth order ODE. ODE may be non- linear, implicit, and any order. Source code included ... it's short! Great teaching tool!
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 Calculus level 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-*.?
Pulse shaping filter program that finds the pole-zero locations of a transfer function, H(s), for a matched filter. H(s) equals a -desired- signal (Yout) divided by a given input signal (Yin). Both Yout and Yin are functions of frequency.
Group delay may also be calculated to compliment a given data set, thus, providing a flat group delay.
"Callisto" is freely distributed program for analyzing and processing of data obtained by atomic-force microscopes.The program is based on effective algorithms of correction of specific image distortions."Callisto" allows to work with the data recorded in .spm format. Support of Veeco/DI (NanoScope III, NanoScope IV) and NT-MDT file types. The opportunities of the program are constantly increased.
StatAssist displays graphs and related properties of more than 40 probability distributions. It is a great time saver for anyone who deals with statistical distributions. With StatAssist, you don't need complex statistical tables - it calculates moments, quantiles, and tail probabilities as you modify distribution parameters. StatAssist also provides an efficient random number generator, and a visual distribution gallery.
Winter Town 3D Screensaver makes your desktop sparkle and sing with a fresh holiday spirit. As soon as it comes to life, you find yourself in a small winter town on a still night. You will enjoy the beauty of the silent streets and houses with brightly-lit windows and feel the tender kisses of wanton snowflakes, melting away on your rosy cheeks. And, of course, there will be an ever-green shining happily with festive colored lights.

FC-Win (tm) is a front-end program for Fortran Calculus (tm). The Fortran Calculus (FC) language is for math modeling, simulation, and optimization. FC is based on Automatic Differentiation (AD) that simplifies computer code to an absolute minimum; i.e., a mathematical model, constraints, and the objective (function) definition. Minimizing the amount of code allows the user to concentrate on the science or engineering problem at hand.
