CurvFit (tm) is a curve fitting program for 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 and/or 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, etc.). Helps learn 1) whether math model is good for given data; 2) convergence implies a reasonable solution; 3) how to select new starting initial parameter values. See comments in EX-*.? files for ideas on how to converge via solvers. Equation Calculator and Hardcopy Plot prints are now (6/2005) available.

Robot4 (tm) is a Robotic Arm Movement program where the arm is moved from a given position to a desired position. The program finds the angles necessary for the desired position. (I think this is the idea!) Problem came from NASA. Robot4 is an Inverse Problem(IP) example. It wants to solve how to move from starting point 'A' to target point 'B'. Solutions to IPs are easy with a Calculus-level programming language. See file 'Rob4User.fc' for solution code.

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. See how zero padding effects your results. Manufacturing companies take note! Some estimators can detect signals 50 to 100 dB from main signal. See documented example! The unwritten rule of '30 dB is okay' (i.e. hidden) is no longer true.

Needn't traditional OMR reader and specialty answer sheet--This soft is a kind of test tool widely used to look over answer sheet automatically, quickly and cheaply. To use the soft, all you need is to equip general PC and digital camera ( or scanner, or digital webcam, or digital vidicon, or PC camera ), and the soft support to auto analyse achievement and output achievement to print. Extremely low cost: Adopting the computer in common use and digital camera( or scanner) as the platform of hardware, cooperating with the PC OMR software, all the system cost is much lower than the traditional OMR reader system. Furthermore, the PC OMR software allows that the answer sheet can be made of general paper by fast print, copy or offset, needn't specialty answer sheet which can be read by traditional OMR reader, so you can reduce paper cost effectively. Simple operation: Adopt standard WINDOWS operate interfaces, the general user needn't be trained to use the software. Stronger function: The PC OMR system is much flexibler than the traditional OMR reader system. It supports using mixing types of answer sheets, offer multiple inspection measures to guarantee that it is accurate to look over answer sheets. It also offers functions of overall achievement analyse and test paper analyse, and the achievements can be saved and printed directly. Well unfailing performance: The system adopts artificial intelligence analyse technology. It is effective to identify the answer sheet which is blurred, distorted or scrawled by mistake. And the answer sheet image can be corrected by hand in case of necessity. So the system has a very strong self-correcting ability to guarantee the accuracy of looking over answer sheets.
