I'm seeking someone who wants a website that has 5 Apps for Windows:
•   CurvFit™ application solves fitting data to an math expression; recommend the Lorentzian series for real world data problems. Sine & Damped Sine series are also available.
•   FC-Compiler™ application is a (free) Calculus (level) Compiler that simplifies Tweaking parameters in ones math model.  FC solves Algebraic through Ordinary Differential Equations; Laplace transforms; etc. FC is based on Automatic Differentiation that simplifies computer code to an absolute minimum; i.e., a mathematical model, constraints, and the objective (function) definition.
•   ODEcalc™, an Ordinary Differential Equation (ODE) Calculator!  Solves Nonlinear ODEs. State your equation, boundary/initial value conditions and it solves your problem!
•   Match-n-Freq™ solves pole/zero locations for a matched filter that is known for pulse slimming or shaping characteristics. Program determines optimal transfer function, H(s).; and,
•   SpectrumSolvers™ provides 13 spectral estimation algorithms for comparing Power Spectral Density (PSD) results. Algorithms include Akaike, Burg, Durbin, Maximum Likelihood Method, Mayne-Firoozan, Prony, Yule-Walker, and et al.

These Apps are for Engineers/Scientists; e.g., one app is a Calculus (Level) Compiler that can solve most continuous math models.  My site has been in development for 30+ years and has 400+ visitors per day [just hit 500 for the 1st time :) ].  Google suggests it will bring in $5,000 / month!

My website,, tries to show Engineers / Scientists how to solve their math problems from industry. The key is a (free) Calculus (Level) Compiler that solves most continuous math problems in Industries.

My compiler got its start at NASA's Apollo Space program back in the early 1960s. Known as Slang back then, it got the USA to the moon and back. When introduced to Industries in 1974, it was then was called PROSE. Today it is FortranCalculus (FC).

If you were a manager or CEO and had the choice of a simulation design versus an optimization design, which would you pick?

Train Educators: Continuous Modeling, Simulation’s & (Mathematical) Optimizations.  Optimizations require an Objective (function).  Today's Engineers & Scientists solve problems with a “Find X” mind-set.  With some Operational Research training they could expand their thinking to a “Find X to Optimize Y” mind-set.  Then they would be ready for Optimizations, Calculus (level) programming and software.  (This would drop today’s design times that require months even man years to one or two days!  Manufacturing processes could be optimized to the days demand and thus maximize their profits.)

“Find X to Optimize Y” thinking among professors will cause most Engineering & Science textbooks to be rewritten with optimization examples and discussions.  This will be great stuff for industries and government; applied engineering and/or science not just theories.

Marketing is the only step left before my website is completely functional, interested?
