LASER CLEANING OF HISTORICAL MONUMENTS Vadim Parfenov, Anastasia Gerashchenko, Mikhail Gerashchenko, Irina Grigoryeva
Results of experimental work on laser cleaning of historical copper monuments are presented. Surface cleaning was carried out by means of pulsed Nd:YAG laser (wave length of 1064 nm, pulse duration of 30-110 μs, energy density10-25 J/cm²). Efficiency of laser treatment was controlled using X-ray fluorescence spectrometer. Performed investigations demonstrated a high efficiency of laser cleaning and possibility of laser use with specified parameters in restoration of copper monuments.

PHOTONICS AND OPTICAL INFORMATICS
INTERACTION LAWS OF COUNTER-PROPAGATING LIGHT WAVES CONSISTING OF FEW OSCILLATIONS IN THE NONLINEAR DIELECTRIC MEDIA Elizaveta Buyanovskaya, Kozlov Sergei A
Mechanisms of counter-propagating light waves interaction from low fluctuation count in non-linear dielectric mediums are theoretically considered. The analytical solution of the equation describing the field dynamics of counter-propagating light waves from low fluctuation count, interacting in the dielectric medium with instantaneous cube nonlinearity is obtained. Changes of light pulse time and spectral structure under counterpropagating pulse interaction are given. The efficiency of these phenomena is shown to be determined by oncoming pulse energy and is independent from its duration and spectral structure.

A SET-THEORETIC APPROACH TO THE LOGICAL INFERENCE IN KNOWLEDGE BASES Bessmertny Igor Alexandrovich
The paper concerns to the problem of combinatorial complexity of inference in artificial intelligence applications based on production rules. An approach to speeding up the knowledge acquisition is proposed that specifies indexing the facts and operations with sets of indices to prune unnecessary facts. In contrast to the most known algorithms that provide pre-collecting facts in nodes of the search tree, the indices exist apart from the rule sets, that allows disjointing bases of facts and bases of rules logically and physically and to simplify the knowledge base updating. An opportunity of alternation the matching оf rules to set-theoretic operation on tuples of variables is proven.

NON-STATIONARY IMAGES СLASSIFICATION AND DEVELOPMENT OF SOURCE CODING ALGORITHMS ESTIMATION METHOD Igor Zubakin, Fahmi Shakeeb S
The algorithm of an efficiency estimation of various image compression methods (methods of source coding) on the basis of the non-stationary measure is offered. The technique of efficiency estimation, using compact representative sample of images, ranged according to non-stationary and broadbandness is generated.
We develop a performance model of solving computational tasks with variable size on distributed systems. For this purpose we extend a performance model of systems with schedule to allow for stochastic nature of global optimization problem. In addition, we consider an experimental method to estimate task size and calculate a confidence interval for efficiency. Finally, we show that a real distributed system solving a cluster conformation problem follows the model within estimated accuracy.
ACTOR EXTENSION OF JAVA LANGUAGE IN MPS ENVIRONMENT Anna Zhukova, Maxim Mazin
The actor extension described in this article adds parallel functional constructions to imperative Java language. Such an extension is useful as it makes parallel programming in Java much easier. Actor model implemented by the extension is well used in functional programming language Erlang. The choice of Meta Programming System (MPS) as the actor extension creation tool made it possible to create an integrated development environment for the extension automatically, moreover, the extension is compatible with other language extensions created in MPS.

NANOWHISKER GROWTH UNDER ELECTRON BEAM IMPACT: MATHEMATICAL MODEL Sergey A. Chivilikhin , Alexander Golubok, Ivan Mukhin
We present mathematical model of nanowhisker growth at the conductor surface in the vacuum chamber of scanning electron microscope under focused electron beam impact. Carbon ions with positive charge come out from chamber surface and are captured by electron beam field. Ions move along electron beam and subside at nanowhisker surface. This process provides nanowhisker growth. In that model electrical field and beam potential are approximated by electrical field and potential of uniformly charged wire. For that simplification Vlasov equation is written, that gives equation of nanowhisker surface movement. By numerical methods we simulated and visualized the process of nanowhisker growth. Computing program builds dynamic grid, which simulates growing whisker – dynamic growth in real time. Obtained results go well with experimental data.
