Various technical object diagnostic systems and process control systems based on the diagnostic results are widely spread in different fields of industry. In most optical inspection systems and diagnostic system of details and construc-tions control and diagnostic processes are represented as analysis of half-tone monochromatic images of item structure. The use of X-ray films underlie defectoscopy radiographic method which is the most prevailing of all well-known radiation con-trol methods. There is an essential disadvantage of the method: under the influence of primary radiation energy scattered radiation changes quality of image, reduces its hardiness and sharpness, so the method doesn’t appear to be sensitive. Due to this effect small-size defects are hardly detected. It is considered that the quality of spot welded joints may be improved by means of their X-ray analysis automation. Pop-ular analysis and image processing systems (Adobe Photoshop, Paint.NET, GIMP ) were analyzed along with their applica-bility to the problem of the analysis of spot welded joints digitized X-rays. There is a table of programs features comparison in the field of consideration. SOWA 193 scanned X-ray analysis pro-gram and such expert systems as ImageExpert and Ident Smart Studio are separately regarded. The conclusions about the existence of topical problems concerning X-ray analysis and existence of full bundled software applicable to X-rays are made.

The development of sapphire production technological process mathematical models and optimization algo-rithms are described. The models of sapphire growth parameters influence on crystals quality are presented. Sapphire crystals temperatures distribution simulation was made. The heat and physical properties influence on sapphire crystallization process is considered. The method of final volumes on unstructured grid is used for simulation. This model allows defining the tem-perature gradients in the crystals formation zone. It also can be used for thermal fields’ description when growing crystals from various materials. The estimation scale of parameters influence on crystals quality was developed. It allows comparing the real sapphire production parameters with the parameters on the developed scale. This scale, suggested mathematical mod-els and algorithms were used for sapphire production information and expert systems. These systems allow defining the in-fluence pattern on crystals growth, choosing the sapphire crystals optimum growth modes, presenting the crystals quality cat-egory forecast. The research results and software give full information about sapphire production peculiar properties and can be used effectively for technology optimization.

The article provides a comparative evaluation of WAVE and Morlet wavelets application in continuous wave-let transformation of medical and biological signals. Using Morlet wavelet application in real time processing the EEG data is difficult. That is why the possibility of replacing it with the WAVE wavelet without significant loss of information content of the coefficients matrix of the wavelet transformation was analyzed. The article proves the replaceability of the Morlet-wavelet with the Wave-wavelet in EEG processing. From henceforth the construction of matrix local maximums W2(a, b) string (LMS) forming EEG is possible. Under some conditions associated with registered signal duration and LMS drift in frequency domain, this replaceability is possible. In case of LMS analyzing in time domain and researching LMS drift in fre-quency domain with high resolution, the substitution is incorrect. It limits using Morlet-wavelet in real-time systems for EEG analysis.

The magnitude of the process energy consumption is influenced by many factors: the circuit configuration of distribution networks in the billing period and the parameters of its elements; circuit transmission lines and the nature of the connection load, parameters of the network mode, the interaction of different electricity streams, incompleteness, inaccuracy, ambiguity of the initial information, the degree of reactive power compensation, power quality, the actual state of electric mains. The task of normalization is the highest possible valuation of factors significantly affecting the value of the technolog-ical standards of energy consumption. There are methods and algorithms of losses modeling realized in the form of in DELPHI program system for estimating the error rate of the square form by simulation modeling electrical loads diagrams for the duration of a continuous function allowing to improve the accuracy and flexibility of the energy losses modeling in distribution electric mains. The article of-fers dependences for shape factor of exponential dependences load diagrams. Simulation takes into account the errors in the calculation of the loss of the head portion parameter uncertainty associated with the measurements of electric power supply, voltage, coefficient of the head section load curve and specifying resistances depending on the ambient temperature. Software system is operated to plan and regulate the energy losses for electricity distribution networks of Azerbaijan power system.

One of the main issues for the future planning of the power for different regions (regional or interconnected power systems) of the United power system of Russia is the adequacy analysis. It requires large amounts of probabilistic in-formation about the work of lasing and и network equipment (damage rate, repair rate and so on) and a lot of longtime calcu-lations. Some calculations for reliability engineering reasons could take up to several hours or even days. One of the ways to speed up the whole analysis process is the usage of modern hardware based on parallel data processing. Nowadays there is large variety of such devices suitable for different platforms and applicable to solve different calculation tasks. It is necessary to decide which of them is possible to use with high level of the performance for the adequacy analysis and how to adapt se-quential algorithms on the parallel architecture. This paper describes different strategies for the adequacy analysis parallelization on such modern device as multithreaded central processing units. Several aspects of graphics processing units usage is also considered. The base of described experiments is programming and computing suite «ORION-M» developed by the Komi SC UrD RAS department of energy. It proved itself as a good device for several years of using.

The issues of time category representation in artificial worlds models including methods based on the concepts of linear, cyclic and branching time are considered. The problem of time representation in informational models is still actual. Basically it is connected with the unsolved problem of time nature in the modern physics and philosophy. One of the fields of the computer science is related to temporal databases. Its purpose is to conceptualize time category and reflect the dynamics of data domain changes. The temporal databases have following characteristic features: the absence of the necessity of irrelevant data removing, the support of the concept of current time and the temporal logic operations. In the context of the artificial worlds models, temporal databases can be used to store the information about the artificial world evolution. This paper offers to use the notion of temporal scales in artificial world’s models for conceptualization of the time cate-gory. The temporal scale is a function which allows normalizing informational snapshots of events in time. Event is for-mation act of qualitative or quantitative value of parameter belonging to the real or artificial world object. It is a result of measurement which can be kept in a database. Temporal scales allow setting and reflecting properties of time in a model: discreteness and continuity, limitation or limitlessness, uniformity and non-uniformity, linearity, recurrence, presence or ab-sence of branching. The modeling of temporal A- and B-rows is also possible. It is established that the choice of the time representation concept influence on results of the artificial world evolution modeling.

This article describes new approaches for creation of forgings local CAD based on a design paradigm which unites all designing objects in the general project on the basis of parent object, a detail. The design organization of system al-lows adjusting the accounting and the opportunity of a manipulation with set of forging variants and technological processes for a detail of the same designation. Such situation often occurs in short-run and single-part production where engineering changes should be quickly processed by designing system. The developed design paradigm raises quality of technological processes design and serves as a platform for embedding local CAD in the integrated control system of product life cycle. Unlike technological processes design systems of mechanical treatment, forgings CAD is difficult to duplicate on different enterprises in virtue of specificity of forging operations and the forge manufacture organization. The hybrid approach of sys-tem construction is applied to increase intellectuality of forging CAD and to simplify its adaptation to concrete industrial conditions. In particular the interface of hybrid CAD is described. On its basis forging and technological processes designing will take into account saved up know-how of the concrete enterprise.

This paper considers the program system for description, editing, modeling and verification of probabilistic multi-agent systems (PMAS). The architecture of PMAS and semantics of its work is briefly outlined. Considered program system allows creating several intelligent agents, setting their parameters with various data types and operating message ex-change between agents with set probabilistic communication channels. At every step of work of the system every agent per-forms the program described on some C-like procedural language. There is syntax of this language, its similarity and distinc-tion with C-language, description features of PMAS probabilistic transitions and message exchange between intelligent agents. Therefore, states of agents and probabilistic actions create probabilistic space of states modeled by Markov chains. Markov chains verification is probability calculation of system properties performance defined by special logics formulas (temporal). Verification is performed by model checking method. The algorithm of Markov chain construction for PMAS and some algorithms of the derived Markov chain for temporal logics PCTL and PLTL and for its modifications are realized in the program system. Syntax and semantics of these logics are briefly described. The example of PMAS description in the program system and examples of PMAS verification for some concrete formulas are presented.
