OPTICAL SYSTEM OF VARIABLE MAGNIFICATION IN THE MICROSCOPE LIGHTING APPLIANCE Tochilina Tatyana V
Efficiency analysis of the light flow use in the optical system lighting appliance of modern microscope was done. It is shown that parameters of observational and lighting branches of the microscope can be coordinated by including variable magnification system in the optical system of lighting appliance that will allow to increase tenfold the efficiency of the light flow use. A new approach to the construction of the optical system lighting appliance is necessary. Possible variants of such systems are considered, analytical correlations, defining the size of its components, are obtained.
COMPUTATION OF OPTICAL CHANNEL WAVEGUIDE WITH ARBITRARY REFRACTIVE INDEX ALLOCATION USING B-SPLINE METHOD Gennady Deineka, Vladlena Serebryakova
The universal strategy of parameters computation for channel optical waveguide with arbitrary refractive index distribution is presented in this work. All calculations are performed from the first principle of reduced wave equation (Helmholtz’s equation). The algorithm is based on the finite elements method using B-splines. Calculation results for channel waveguide with defined index profile and various geometrical configurations are represented as well. The comparison of the obtained results with the results by the known numerical methods is given too in this article.
PHOTONICS AND OPTICAL INFORMATICS
THIRD HARMONIC GENERATION AT REFLECTION FROM CRYSTAL OF HIGH-INTENSITY FEMTOSECOND RADIATION Olga Mokhnatova, Putilin Sergey E, Bespalov Viktor G, Kozlov Sergei A
Experimental results of the reflection of femtosecond radiation with a power density of 4 TWt/cm2 and duration of ~ 40 fs from nonlinear crystal of LiF at light falling to medium boundary close to normal were presented. The generation of triple frequency radiation was observed at the reflection from the front face of the crystal. Spatial distributions of triple frequency beam and fundamental beam were recorded. Energy of triple frequency radiation was 10-4 of the energy of the incident radiation. Half-width of light beam spatial distribution on the triple frequency radiation happens to be three times narrower than fundamental beam half-width.

The task is dared in three stages: linearization of nonlinear BDS, formation of dynamic observing process of linearized BDS and observing division over a condition of initial nonlinear BDS. The example is supplied.

INVESTIGATION OF LANTHANUM GALLATES BY X-RAY DIFFRACTION ANALYSIS Olga Pshenko, Lyubov Pyankova
The work deals with the study of phase composition of poorly-type semiconductors - Lanthanum Gallates Perovskite (LaGaO3) doped with a touch of Co3+ (up to 10%) by X-ray diffraction analysis. Comparative analysis of X-ray pictures shows that cobalt impurity concentration growth in the mixed crystals LaGaСохO3 leads to insufficient deformation of cubic crystal lattice with the decrease of elementary cell parameter by 0, 03 nm. Nevertheless, in Lanthanum gallates the local symmetry decrease is possible and it becomes apparent on X-ray pictures as diffraction maximum splitting.

MATROIDAL REPRESENTATION FOR THE ADJACENCY GRAPHS FAMILY BUILT ON A SET OF KNOWLEDGE PATTERNS Vsevolod Oparin, Filchenkov Andrey A, Sirotkin Alexander Vladimirovich
The paper considers a problem appeared in machine learning of uncertain knowledge patterns bases represented as algebraic Bayesian networks. The problem is to build an adjacency graph as a representation of a global (secondary) structure of such a network using its primary structure. Under the given primary structure of an algebraic Bayesian network, the corresponding adjacency graphs family can be characterized with a special matroid. It leads to further results: the sets of minimal adjacency graphs and non-reducible join graphs are equal; a minimal adjacency graph can be built with a greedy algorithm; the vertices number of minimal adjacency graph can be expressed with the vertices number of maximal adjacency graph and the matroid rank.

Modeling of blood vascular system is a wide field for scientific efforts and includes a large number of aspects.

The main part of the work we devote to interaction of elastic fiber model and global blood circulation model. Models interaction makes it possible to research an effect of vena cava filter placement on haemodynamics.
