Description:

LeoCrystal is a software program that performs numerical Monte Carlo modeling of reaction on the surface of the growing crystal for illustrative educational and research purposes. With the help of this program you can estimate influence of effective geometrical sizes of structure elements of the crystal and thermodynamic parameters of the process on the topology and kinetic of the crystallization. As soon a process of crystal growth is presented itself in practically all major technology processes an in depth understanding of complexity of it is essential for professional research in different area of applied science. Particular interest it could be for the nanotechnology investigations permitting off site optimizing design on the molecule scale level. The creative presentation of the surface includes a three-dimensional perspective projection and stereo view. It makes this software a great illustrative toll for teaching of the concept of phase transition for the students of very broad ranges of initial background. Very moderate scientific background is needed to understand a material in this section. Preliminary runs of the program will make a great help to easy accommodate basic concepts. The crystal growth is a phase transition process with sharp border between it and initial feeding phase like a liquid, gas or plasma. The structure element (molecule) of the crystal could be determined as a minimum part of it when a reaction of incorporating its in the crystal will effect with changing energy of the whole system that will be equivalent to the condensation energy of the corresponding mass of crystal. In simple words the molecule is the minimum part of the crystal that behaves as a whole crystal. The principal difference of behavior of molecules in liquids is based on the principle of the long order in the crystals structure. Each molecule has exact position relatively to the other in crystal.

Description:

Comprehensive tool for statistical analysis and modeling of experimental and market data. Universal input from outside data sources: from text or database files; file type and edit in spreadsheet like control; copy/paste from spreadsheets applications like MS Excel or Access; extract curve in numerical form from image chart; image file. Data manipulation procedures permit to new create and modify existing variables using simple formulas or schemes. Syntax of formulas incorporates itself ability to use indexing variables that permit to create differential variables. Statistical schemes of the program incorporate: distribution of one variable with comparison T, Erlang and Poisson probability; conditional distribution depend on values of other parameters; two arguments distribution with 3D presentation or color map presentation; curve fitting with variety schemes to define modeling formula; peaks revealing with base line elimination and special emphasizing on mass chromatogram; 3D presentation of function of two arguments and with plane, parabolic and user formula multivariate approximation; near neighbors method for multivariate estimation; creating score variable that reflect probability for given variable be large then chosen number and algorithm for calculation of the score from other significant parameters. Found approximated coefficients are accompanied with their calculated standard deviations. The accuracy of presentation of their numerical values can be set by user or automatically defined on the base of stability of their computation. Automatically run a comprehensive statistical analysis by one mouse click. Convenient user interface permits to design professional looking visualization of the data and modeling formulas. Color, size and shape of point marks and formula lines as well elements of graphic including font of the description could be easy modified. A report of present statistical analysis can be saved in form of MS Word document or HTML page.
