The article discusses the development of algorithmic and software for an intellectual control system for the development of the synthesis of active pharmaceutical ingredients. Based on the analysis of the scheme of the quality control system, the efficiency and safety of medical products, the authors showed that the only non-certified stage in the life cycle of the development and production of medi-cines is the pharmaceutical development stage, which includes the APIs synthesis and the GLF compo-sition development. The authors showed the advantage of the continuous synthesis scheme for the production of active pharmaceutical ingredients over the periodic synthesis scheme. The authors gave a systematic ap-proach to the proposed development based on the implementation of the QbD principle. They devel-oped a scheme for the formation of a global criterion. The authors formulated a range of conditions in which the research is to be performed, while with respect to each condition, the quality of functioning is evaluated by an independent criterion. There are the information models for the control system for the continuous synthesis of diphenhydramine APIs in the IDEF0 notation. The authors proposed an approach to the development of information and software and algorithmic support for the continuous synthesis of drugs. The authors developed the mathematical models based on regression analysis to control the process of continuous synthesis using an intelligent control sys-tem. There is the algorithmic and software based on the freely available Scilab software package for managing the process of developing API synthesis using multi-regression regression models and the Hook-Jeeves optimization algorithm. There is a graphical interpretation of some of the process study results of obtaining the API of di-phenhydramine (diphenhydramine) in an experimental continuous synthesis plant. The authors ob-tained a set of graphic solutions that allows to optimize a number of the synthesis process quantitative indicators of the active pharmaceutical ingredients.

The paper deals with the problem of modeling the liquid and gas flow in systems consisting of contain-ers of various volumes interconnected by pipes of various lengths and widths. The proposed model is based on a system of differential equations describing the change in sub-stance mass in containers as well as the change in the substance flow magnitude in pipes. In addition to container and pipe parameters, the model takes into account various parameters of liquids and gases, such as density, temperature, and molar mass. The description is accompanied by formulas with neces-sary explanations. The paper also discusses the problems caused by high computational costs to run such models, time costs. It proposes a number of heuristics to reduce those costs significantly. The authors discuss each idea, interconnections between applications of the ideas, as well as their limitations. The authors describe the key technical aspects of model implementation, including the proposed heuristics and the ability to configure various parameters that affect the accuracy of the calculation and its running time. The paper shows that the proposed model can be extended by adding the elements that model the operation of various devices, such as valves, gearboxes, and pumps. Each device has an implementa-tion model. Finally, the scope of the model and a computer implementation are discussed. The authors also mention some issues beyond the paper scope, such as implementation of parallel computing.

The paper proposes an approach to the management of dynamically changing systems. Such systems has a response that during the system operation their state may: the list of the equipment, the load of the system and the functions performed by the system. It is required to choose the values of control pa-rameters depending on the system state in such a way as to provide the required values of the charac-teristics of the system. To solve this problem, the authors plan to use optimization algorithms with self-learning: direction-al random search algorithms with self-learning and ant algorithms. These algorithms, operating by trial and error method, allow you to tune in to the current state of the system. The introducing into the algo-rithms the memory of successes and failures on the previous steps helps to achieve it. The main idea of using self-learning algorithms to control the system is that we will consider the control problem as an unconditional optimization problem. The elements of the vector of optimized variables are the control parameters of the system. The authors consider the algorithm steps as possible actions of system control (operations of changing control parameter values). The objective function can be set in one of two ways: by the calculation of the total mean probable characteristics error of the system from the required ones. The weights help take into account the characteristics importance by summing deviations; the researching of the maximum characteristics deviation of the system operation from the required ones. The proposed management approach allows the unstable environmental behavior, limited managed system information and allows you to take into account the presence of many system characteristics, their values must be maintained within specified limits. If the system elements failure does not lead to the whole system failure, but only worsens the system characteristics values, this approach will mini-mize the characteristics values deviations from the required. A limitation of this approach is the transition process allow ability by changing the system state. In this way, the algorithm will require a number of steps for retraining. Some steps cause disturbance the required system performance.

Modern video surveillance systems are very popular to prevent and investigate various illegal inci-dents. The main disadvantage of traditional decisions in this area is that the operator directly assesses the current situation and makes a decision. With a large number of monitored cameras and due to the human factor, there is a high probability of increasing the time delay in determining the dangerous situ-ation. This leads to significant damage, especially in cases where it is necessary to respond promptly to an incident. Such cases include, for example, the situation of carjacking. These circumstances necessi-tate the introduction of systems for the intellectual analysis of video data. This paper submits a method for recognizing situations of car theft from parking based on stochastic grammars and deep neural networks. Recognition of an incident is at two main levels: at the lower lev-el, event recognition occurs, at the upper level, the situation as the most probable chain of events cor-responding to the grammar of car theft signatures. The analysis of the identified objects, their relative position, the dynamic characteristics of the trajectory of movement and the characteristics of the peo-ple’s postures, fills up the detection of possible hijacking events. The deep neural networks recognize the objects and people poses. These networks have a high degree of reliability. The article developed a simulation model of the system of recognition of the situations of theft of road transport, which based on the object detection module using a deep neural network. The history of certain objects in previous frames and, if necessary, data on the posture of a person improves the as-sessment of the reliability of event recognition. To describe the possible scenarios of car theft, the authors developed a stochastic grammar and cre-ated the test utility based on it. The test results of the developed method on the Mini-deone video da-taset showed its efficiency.

This paper appoints the problem actuality of the holding capacity assessment with dangerous freight. The holding capacity transcendence of such hoarder is connected with the large environmental or fi-nancial loss; accordingly, it is a remote contingency. Legally the drive loading is a service operation of the received application. The machinery of the theory congestion system is for modeling of the received application process. The authors showed that it is necessary to take into account the stream no uniformity of orders in service operation modeling. The input and output stream orders are vary wildly in the extent of incoming and out coming freight from it. In the input stream, the orders come by batches, but the output stream has unicast orders. The authors offer to use the analytico-statistical method of the extreme values and the behavioral model of the sequence in the buffer with the limited capacity for solving the original problem. The analysis of the order losing process in the overcrowded buffer of the terminal capacity by the station-ary system of mass service is reduced to the analysis of the sequence build-up and build-down on the refresh interval. The authors got the expression for the low value calculation of the discard probability in the termi-nal capacity buffer in the form of the analytico-statistical value. The authors offered the acquisition and computing technique of the sampled data. Performing sequential steps it makes possible to estimate the required capacity of the final buffer according to the waste tolerance probability.

The paper proposes the structure and the main automated system modules for calculating the annealing modes of glass products. There is the problem of modeling temperature fields for cylindrical products with asymmetric con-vection-radiation heat exchange with the environment and enclosing surfaces of technological equipment. The au-thor formulated the possibility of solving the two-dimensional temperature problem in the Matlab programming environment. There was the parabolic function in the performance of the temperature field-modeling problem in cylindrical glass products. This is one of the Matlab tools for solving differential equations of parabolic type with complex boundary conditions. There are the programs based on the standard fmincon function in Matlab that allow to identify the coeffi-cients of artificial convective heat exchange between the air and the product surface in each of the zones by using the determinate thermal material characteristics and the temperature-time regime parameters in the annealing fur-nace. There is a parameter identification example of the convective-radiation heat transfer in the sort glassware (glasses) annealing furnace based on the temperature field-modeling program in Matlab. The author considered the program development features associated with the need to take into account the changing initial and boundary conditions at each temperature-time stage annealing of the product. There are the program codes of the main program, the modeling temperature field functions the CilinderHolParabolic1 and the boundary conditions boundaryFileHolParabolic1. The author studied the program results and demonstrated a good match of the convective heat transfer coefficients with their physically reasonable values in artificial convec-tive heat exchange in annealing furnaces of glassware. The attained condition identification results of the convec-tive-radiation heat exchange with the environment and enclosing surfaces we can use to optimize the heat treat-ment of cylindrical products.

Corpus data management systems today help to solve a number of urgent problems connected with the computer linguistics. Particularly, this is the source documents processing, automatic morphological markup of them, storage and modification of corpus data with morphological markup, the search in-quiry execution (selecting data), and integration with other applications. In the automatic morphological text markup of the electronic corpus, there is a problem when two or more sets of morphological properties marked out the same word form. It is a morphological ambiguity. The authors developed a module for manual resolution of morphological ambiguity, which can help in solving this problem. This article discusses the architecture of the module for resolving the morpholog-ical ambiguity of the corpus data management system developed for managing the Tatar corpus, and describes the organization of the database based on the transactional approach to data storage. The article proposes in detail the architecture of the rupture modulus of the software morphological ambiguousness of corpus data. It is for the tartaric corpus management. In addition, the author de-scribed the database organization. It relies on the transactional way to the strategy for the data storage. The paper in detail describes the architecture of the module software, which is part of the Tugan Tel corpus data management system. Due to the architecture of the corpus data management system, such modules can quickly integrate into the system and have no effect on the other module operation. The module database organization for the morphological disambiguation described in the paper, al-low going over for solving the other computer linguistic problems, such as automatic morphological disambiguation and improving automatic morphological markup of texts in the electronic corpus.

Metal forming is widely used in the manufacture of products for various purposes. There are crimping operations with the help of a technological tool of crimping matrices to reduce the transverse dimen-sions of the end part of hollow thin-walled cylindrical parts. Receive a crimped cap of cylindrical cans, aerosol containers packaging, different adapter pipes and other products. The high costs of experi-mental work and production of pilot batches lead to the relevance to create automatic engineering sys-tem of the crimping operation techno - process. The article presents a business processes sequence UML-diagram of the designing crimp matrices. The purpose of setting up the production technology, of course, is to get such sequence in which the product information will be the least time to get to the work department with the customer without re-turning to the design stage. This, in particular, requires fast and accurate automated control at the key stages of production. The authors describe in detail the interface and the operation principle of the computer-aided design software module of the crimping technological process. There are the formulas for calculating the number of crimping operations, the presentation structure of the basic data. The de-scribed algorithm allows the flexibility to assign the processes parameters of the deformation and to control the strength characteristics of the functional products. The developed software for the design of the crimping process allows the calculation of parameters such as the operation number and the sys-tematic diameters of the crimp dies. For modeling in finite element analysis system, we can use the program output data. The authors made a conclusion that the combination of the developed application software and systems of finite el-ement analysis will significantly reduce the production time and cost by reducing the time required for the design of the crimping process, reducing the sets of experimental technological tools.

Nowadays, the problem of providing a high security level of mobile devices, such as smartphones and tablets, through biometric approaches is particularly relevant. The paper proposes an anti-spoofing method for a limited number of images. The authors investigate the detection of spoof attacks using printed photos and screens of mobile devices and monitors. They show the relevance of the research and current unresolved problems. The paper considers the structure of a typical Liveness system consisting of a source (camera), pre-processing of received images, face detection, feature module and a classifier. The study shows that pre-processing of the obtained images is one of the most important parts of the system, since the signs of spoof attacks are difficult to detect due to the extensiveness of augmentations. There is a small review of modern architectures of convolutional neural networks (called encoders in the current architecture terminology). It is also shown that the linear output of convolutional neural networks can be used as an input for LSTM-type recurrent neural networks. It is noted that the best face detection algorithm in the current architecture is MMOD method. The resulting Liveness system architecture is presented as a combined approach consisting of two components: a convolutional neural network receiving embeddings from each frame and a LSTM re-current neural network that uses these insertions on the input and learns to remember sequences of cer-tain frames and their characteristics. The authors present experimental results showing the accuracy indicators of the current develop-ments in this field when computing power requirements are low. This methodology allows determining fake photos by several frames.

The reform of the waste products distribution touches many aspects. The questions of the rational or-ganization of the waste transportation are actual for the all-Russian regions. The one of the directions of the development territorial arrangement is a reduction in expenses for fuel waste delivery to the waste polygons or the places of their utilization, a tariff cut for the citizens. For developed the under-lying territorial scheme of a waste management we need the carrying-out of an analysis and the waste direction control with consideration to the waste formation dynamics, the spatial features of the munic-ipal territories, accumulation rate determination of the waste on the polygons. Specialists solve the problem of the road complexation of the refuse transport for the electronic model development of the waste management scheme. The paper has a look at the number of the most identified models and ways to the material allocation in the spatially-regular system. There is an estimate of its using for modifying of the territorial scheme of a waste management. The specialists recognized that one of such approach-es must not directly use to the waste management. The using the well-known algorithms of the transport logistic disabled to take stock of the combination of the factors, representative for a mature model in a transportation of waste region. There needs their combination and refinement. There is a collection or-ganization description, utilization and waste disposal, and a direction control of a municipal solid waste from the local centers to the polygons. The authors showed the algorithm of the complexation cargo transportation route. There is a script package based on the offered algorithm, with help of this the specialists made the analysis of the mod-eling waste transport flows. The complexation results of the march allow developing the whole and consistent electronic model of the territorial waste management scheme.
