You can easily export the results to various formats, or print them.

With StatAssist, you don't need complex statistical tables - it calculates moments, quantiles, and tail probabilities as you modify distribution parameters. In addition, it includes an efficient random number generator, a visual distribution gallery, and a comprehensive on-line documentation.

EasyFit allows to easily and quickly select the probability distribution which best fits to data, reducing your analysis times by 70-95% over manual methods. It includes numerous features designed to save you time, prevent analysis errors, and help you make better decisions.

An integrated environment provided by EasyFit includes data management, analysis, and reporting capabilities ensuring the high quality of your projects. It is very easy to learn and use - requires only a basic knowledge of statistics, so you can master it in a day or two.

The key feature of EasyFit is the ability to automatically fit over 40 distributions to sample data. Advanced users can also apply the flexible manual fitting capability. After the distributions are fitted, they are ranked accordingly to the goodness of fit tests (Kolmogorov-Smirnov, Anderson-Darling, Chi-Squared) allowing you to select the best model.

A variety of high-quality graphs (probability density, cumulative probability, survival, hazard, P-P plot etc.) can be used to visually compare the fitted distributions and make sure you have chosen the most valid one. Finally, you can apply the integrated StatAssist tool to get a comprehensive information (moments, quantiles, probabilities) on the selected distribution.

Additional features include hypertext reports, random number generator, and visual distribution gallery.

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.

Zoommy is a handy and feature-rich on-screen magnifier, making life easy for visually impaired PC users and enhancing working abilities of design professionals. Not only does it magnify the selected area up to 30x, but it can also measure it, take screenshots and show pixel color info. Also it has the Slow Mouse mode providing the best zooming experience. The tool is delivered in a refined interface where every feature is at hand and available at one click.

With this tool you will be able to see each and every detail. Moreover, unlike similar software, Zoommy’s magnifying glass works for both zoom in and zoom out, allowing zooming from -4x to 30x. Thus, if you need to see a distant view of some large image, it will also be of help. With Zoommy, you can quickly measure the size of the selected area in various units, including centimeters, inches, percent, etc. Another feature is that you can copy an image from the lens window to clipboard and save it to a file, i.e. you can make screenshots of zoomed objects. Zoommy also comes in handy when you need to know the color of some pixel. The pixel color is shown in RGB, CMYK, HSV, Lab and in two hexadecimal formats. It can match the color of the pixel with one of the “Web colors” which is especially convenient in web design.

Zoommy is designed to provide users with maximum comfort and flexibility. The software has the unique Slow Mouse mode, allowing you to navigate with pinpoint accuracy. The mode can be quickly turned on\off by a hotkey and stops any time you minimize the tool to system tray. What’s more, for your convenience, the pointer in the lens window is shown in such a way that you can clearly see its actual position and easily point out the needed pixel. You can adjust various settings, for example, change lens’s size and position, fine-tune brightness, contrast and choose one of the following color modes: normal, inverse, black and white or gray gradation

Typical OCR software can handle only binary images with black pixels representing text and white pixels representing background. It isn't unusual in modern documents to have inverted text zones and normal text zones within the same document.


The document structure analysis and character recognition are usually done in several phases:
scanning
thresholding
skew detection and correction
despeckle or speckle removal
line removal
border removal
detection of preprinted elements (like boxes)
page orientation detection and correction
layout analysis
classification
character recognition (normal and inverse)

Each step must be completed well enough for the performance of the sequence and result to be successful. ZoneHelper detects and automatically converts inverted text zones and change white-on-black text to normal black-on-white text.
ZoneHelper expects as input a monochrome image.

The page orientation of a document is defined as the printing direction of text lines. Therefore the page orientation can be in either horizontal printing mode (portrait mode) or vertical printing mode (landscape mode). The page orientation correction is crucial for any automated entry system for printed documents. LandscapeHelper detects landscape pages (rotated with 90 degrees) and automatically put the image into the right position for further processing steps (character recognition).

Texture Workshop is a multifunctional toolbox which allows to turn practically any picture into a repeatable tile very quickly and easily. Such tiles are used as backgrounds of webpages, as wallpapers, as textures for 3D objects and for many other purposes. The program can be used conveniently both by a beginner for creating the very first own home page and by a professional web designer for the large scale work. It can also effectively substitute the well known expensive, "heavy" and demanding experience graphic applications if you need to edit quickly your pictures of any kind. The unique feature of this toolbox is the "tilization procedure". You can take any picture with similar objects (leaves, stones, beans, nuts, bolts etc.) and with a single pressing a button process it so that the right area of the picture will imperceptibly flow into the left area and the lower area will flow into the upper one. In other words, a real repeatable tile will be obtained. The same can be done with a small fragment of a texture (marble, wood, water waves, tissue etc.) to produce a smooth and limitless surface.
