Electronic structure and total energy of various isomeric forms of coelenterazine has been calculated by methods of quantum chemistry both in one-electronic approach, and with correlation effects. It is shown that the account of electronic correlations allows choosing structure of coelenterazine CLZ (1H) as most probable of possible isomeric forms.

In this paper the problem of modern search systems connected with documents ranking is shown. To solve this problem it is proposed to use the modified algorithm HITS in the process of searching and processing information. This approach helps to solve the problems of search, relevance determination of the information and also to rank system response.

The article presents description of hardware and software system designed to study the kinematics and dynamics of planar lever mechanisms, and providing for synthesis of Assur groups.

In this work the author dwells upon informatics domain knowledge projection on social and pedagogical processes. Besides, the author performs comparative analysis of information signal transmission theory by means of networks and pedagogical influence of information signal during lectures, and identifies potential domain in the global utilization of the information signal formation theory in social systems.

In the article the author considers the present situation in the Russian Federation, resulted from rapid growth of quantity of legislative documents have being passed. The significant part of these laws is of corrective nature; it means that such documents contain references to other certificates. Analysis of a great number of documents with their interrelations is a difficult routine work, requiring the presence of highly skilled specialists. The author proposes a complex approach to improvement of the legal-reference systems and electronic databases by integration into them of the system, realizing visual display of documents, and analysis of correlation for the purpose of their conformity to the norms of lawmaking. Theoretical basis and practical implementation features of the system are introduced in this article as well.

The author considers a new finite element of a beam with low value of transverse shear stiffness. As the basic kinematic variables transverse shear strains are appointed. Results of numerical analysis showing urgency of the model are presented.

Spatiotemporal features of Spring Ozone Anomaly in Antarctica (ozone hole) are considered. On the basis of satellite ozone data and with the help of correlation-extreme algorithm the zonal velocities of ozone in the southern polar stratosphere are calculated. Results of calculations of the ozone hole area for the region where the total ozone was less than 220 Dobson units, and of the mass deficit of ozone in the stratosphere over Antarctica are presented. Close link of ozone mass deficit in the ozone hole with the zonal velocity of the region accumulation the total ozone in the circumpolar vortex for 1996 to 2009 is revealed in this article.

This article reviews a problem of choosing of a structure of space system automated control system. The authors present a model and method of spacecraft control centers selecting. This allows effective forming the optimal set and location of control centers of space system automated control systems.

Intelligent algorithms and method is well-suited to many problems in data processing, where unlabeled data may be abundant. We survey previously used selection strategies for intelligent model, and propose two novel algorithms to address their shortcomings, focus on Active Learning (AL). While has already been shown to markedly reduce the annotation efforts for many sequence labeling tasks compared to random selection, AL remains unconcerned about the internal structure of the selected sequences (typically, sentences). We propose a semi-supervised AL approach for sequence labeling.

In the article we consider mobile means for diagnostics of conditions of EHV power lines of any voltage class, based on object position and angular orientation determination technologies, given by GLONASS and GPS satellite radionavigational systems, and also using modern infrared video devices for localization the overheated points on overhead power lines.

It is necessary to specify the orbit control propulsion subsystem type of designed applied spacecraft(S/C). Nowadays electric propulsion systems (EPS) with wide power range are intensively investigated and developed. Therefore it is expediency to clarify the EPS preferable application ranges with a comparison with other propulsion types. This question is topical especially to small S/C. This article is dedicated to study of this task.

From the analysis of tasks caused by necessity to mitigate and prevent effects of corrosion during scheduled service, the most important one is to define the boundary parameters of corrosion damage.

This work considers a thermal radiation Sunlight simulating in S/C and components of thermal vacuum test. Estimation of factors influencing quality and EFFICIENCY of simulating installations is given. Directions of Sunlight simulators efficiency increase are specified.

The authors offer a method for calculation of intension of refuses and residual resource of safe exploitation of technical object with the account of casual factors. Results of calculations allow to define probability of object refuse and to minimize risk of accident occurrence at the decision of problems of optimization of systems of technical service, and to provide optimum control of safety at exploitation of potentially dangerous objects.

The work contains results of study of kinetic parameters of ceramic mixtures sintering depending on rheological properties of mineralizers. The applied method of defining of kinetic parameters in two non-isothermal experiments enabled to make quantitative assessment of mineralizers efficiency basing on the value of activation energy of sintering the ceramic mixtures with mineralizing additives. The study provided for compiling a sequence of mineralizers efficiency that reflects the pattern of physicomechanical properties improvement and activation energy reduction as the viscosity and surface tension decrease.
