	NLREG | License: Demo |
	NLREG performs nonlinear regression and curve fitting. NLREG fits a mathematical function whose form you specify to a set of data values. Virtually any type of function can be fitted. NLREG includes a programming language similar to C that you use for describing the function to be fitted. Two dimensional line and three dimensional surface plots can be generated. The programming language includes a large selection of built-in library functions (sin, cos, log, exp, etc.) that makes it easy to describe complicated models.. Publisher: Phillip H.

	CurvFit | License: Freeware |
	CurvFit (tm) is a curve fitting program for 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 and/or 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, 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*.

	Curve Pilot for Mac | License: Demo |
	Curve Pilot designed for teaching the basics of color corrections of images created by a digital camera or scanner. The traditional image editors use the curve method for color correction. The drawback of this method is that you don't always understand in which direction you should move certain curve. Curve Pilot offers you a revolutionary new method: simply indicate which color you want to get as a result of color correction and Curve Pilot will automatically calculate the values for curves that allow you to achieve the goal. It will show the curves on the screen and perform color correction. The corrected images can be saved in the JPEG or TIFF formats and the curves can be used for the fine tune-up in another editor, Adobe Photoshop, for example.

	VectorEye | License: Shareware |
	VectorEye is a great raster to vector converter that exports to SVG (Scalable Vector Graphics), Ps, Eps, Flash macromedia and xaml windows vista. It recognizes all major raster formats (BMP, JPEG, PNG, TIFF). Tint area and line converter. Raster images made from pixels acquired from scanner or CCD camera can be translated into scalable geometric shapes. Vector based images are the best way to display high quality graphics with the minimum amount of information. Extracting this information from raster images is a great challenge, and algorithms will probably never replace our artistic sensitivity. Publisher: Siame| Date: 01-09-2007 | Size: 6574 KB

	GoldenGem | License: Freeware |
	Review: This program is considered to be one of the best of the neural network stock prediction programs. It is probably based on, or at least is named after the original 'goldengem' consoles, which are rarely seen nowadays. The usual disadvantage of a neural network is that it's not easy to tell whether or how it is working. By pressing essentially one button to update your shares, and a second button called 'Run/Pause,' you are brought to a sort of oscilloscope display. The vertical slider to the left of the display flashes insistently. . As it is raised upwards, the horizontal green line on the graph (indicating zero) jumps to life.

	Crickler | License: Freeware |
	Cricklers are a new type of word puzzle - a total re-invention of the crossword puzzle for the computer age. Traditional crossword puzzles are incredibly successful but they have several serious drawbacks: (1) They are difficult to construct, (2) Most words are short and often silly -- chosen only because they fit, (3) Matching clues to numbers is a distraction, and (4) A given puzzle is usually either too easy or too hard. Cricklers solve all of these problems while retaining the essence and feel of a traditional crossword puzzle. Cricklers adapt: they become easier or harder depending on the skill of the solver.
