Dynamic Models of Information Processes in Hierarchical Control Systems 000_1.pdf

The dynamic model of situation coverage and control planning processes was constructed on the basis of unified numeration of the hierarchical control system objects. The differential equation system describing information processes was generated for each object of the system. Analytical solutions were obtained for three lower levels of a hierarchy while situation covering and for three upper levels while control planning. Analytical solutions represent dependencies of information resources volumes on time, information processing speed, and initial data volume. The model constructing is based on the condition of information resources volume conservation in case of any transformations. The real ability of the analytical solution of differential equations for objects of all levels is shown. The results of the information processes calculations in two-level systems are considered. The constructed models allow to hold investigations of certain properties of a system promptly and without significant costs in different situations. For examples, such models allow to estimate the control cycle time while changing speed of information processing on objects. On the stages of design, the use of models gives an opportunity to formalize and automate the search of optimal project solutions and provides improvement in quality and losses in cost.

Optimizing System Probability-time Characteristics With the Use of the Simulation Model 000_2.pdf

The currently central problem of increasing efficiency of a real-time hierarchical control system through rational resource allocation and reduction of control document development time was considered. The method of constructing a theoretical dependence of system probability-time characteristics (pTcH) on corresponding objects characteristics was described. The algorithm for developing approximate analytical dependencies based on approximation of experimental data obtained through simulation was outlined. In order to optimize pTcH, the task of allocating resources among objects in a hierarchical control system was formally set and solved. The authors show, that the system simulation model can be used as a target function instead of an approximate analytical dependence with the current efficiency of computers. The simulation model includes a lot of experiments. The random values of control document development time were set during each experiment. According to the structure and the algorithm, system characteristics are defined. Application of simulation models enhances the set of complex system design tasks solved with the use of operations research methods

Modeling and Investigating Dynamics of the Electric Drive of Excavating Machines Swing With the Use of the Combined Optimal Control System 000_3.pdf

Improving quality of the automated electric drive is one of the most efficient and cost-effective ways to improve reliability and durability and to reduce down time in repairing mining complexes. currently in Russia, the excavator park has tens of thousands of machines, about 80% of them are exhausted that leads to the need of repairing works. The rotary mechanism electric drive ring gear repair cost is calculated to be 30-40% of the total excavator cost. Optimizing the rotation drive control reduces the dynamic load of a ring gear. Reducing the dynamic load is carried out with the electrical part of the drive that improves reliability and durability of the system. Therefore, the creation of automated electric drive control systems requires the use of mathematical models. The authors consider the rotary electric drive with the highest number of failures in mechanical and electrical parts of the excavator, with a combined optimal control system representing the voltage inner circuit and the optimal regulating device constructed analytically with the highest number of the anchor chain current, engine speed, elastic time, and speed of the second mass located in the forward channel of the control system. In order to investigate the drive, the simulation model was created in MATLAB program with the use of simulink package.

The Mathematical Models of Telecommunication Systems Used in Integrated Information-management Complexes 000_4.pdf

The article considers the method of effective processing of error-correcting codes combinations. The method is based on the possibility of lexicographical partitioning of code words space into clusters. This process allows to realize the list decoding method of code vectors on a regular basis with the use of a single list, which refers to the cluster number zero. The authors show that the vector of any other cluster with simple transformations can be brought to a vector of the cluster zero. The article proves that the method is applicable to binary and non-binary codes.

Evaluation of the Computer Temperature Regime Stability 000_7.pdf

The temperature regime significantly affects the durability of the computer. Ensuring stability of the computer functioning considers the stability of the heating temperature of the main elements that should not exceed the specified values. The article discusses issues related to the timely warning about a possible violation of the temperature regime stability. In order to diagnose stability, the multivariate statistical control methods are proposed to use. Evaluation of stability is carried out with the use of two criteria: stability of the temperature average level and their dispersion. Independent parameters can be controlled with the use of standard shewhart charts. The algorithms on the basis of Hotelling statistics (for assessing stability of the middle-level temperature measurement process) and generalized variance (for evaluation of the dispersion process stability) are used for correlated parameters. The efficiency of these algorithms can be enhanced through the analysis of non-random structures on the control charts, the use of the warning border, as well as application of modifications based on the cumulative amounts or moving averages weighted exponentially. The multivariate statistical technique of the computer temperature regime control including monitoring in the context of a well-developed process for a training sample in order to separate the parameters controlled for a group of independent and correlated ones, process analysis for assessment of control characteristics and continuous monitoring of the process with the construction of Hotelling charts and generalized dispersion with identifying possible violations of the process based on the presence of significant structures and the use of a warning border. This technique is illustrated by the example of five computer temperature regime parameters control.

Structural and Logical Design Solution Class Generalization With the Use of Design Procedures Representation Adapted Functionally 000_9.pdf

Design of modern products relating to different subject areas and consisting of a large number of components differs by the presence of the technical requirements to the entire product without separate requirements to its components. The design activity results include complete design documentation and product assembly 3D-model. The process of assembly 3D-model formation includes adding 3D-models of components and establishing conjugations between them. In order to construct, correct, and maintain (update or modify) a 3D-assembly, rebuilding should be provided. Typically, the process is carried out through manually handling of parts parameters and conjugations. That requires additional time and labor expenses. The authors propose the solution of the problem in establishing the structural and logical relationships between the components of the assembly 3D-model on the attribute level allowing to link the components and structural objects. Interrelations between the components allow not only to determine their location and link to each other operating with design parameter values but also to modify the design solution without violating its integrity that is not ensured by any modern cAD-system.

The Software Project Management System Based on the Ontology Approach 000_11.pdf

In information system designing process, one of the most important artefacts of project activities is a set of UML-diagrams. In order to ensure development continuity and organization of interaction between the analysts and programmers, the structure of the domain concepts should be provided. storage and processing of domain data and knowledge can be presented optimally in the OWL ontology format. The article describes a tool that allows automated integration of the UML-diagrams and OWL-ontologies. project UML-diagrams are translated into a XMI-format. After that, the ontology is constructed on the basis of the diagrams, which is available for extension by the specialist in ontological engineering. The ontology can be extended by the introduction of rules limiting the opportunities for building UML-diagrams and, as a consequence, for a software product in accordance with the domain. The main advantage of the ontological approach in the management of software projects is checking the consistency of ontology and receiving the associated UML-diagrams as a result. such checks should be carried out when changing the UML- diagrams or the domain ontology that provides consistent state of a system during the software product life cycle. On the basis of the obtained ontology, new software compatible with the already existing ones can be designed. General ontological base of the software can help to minimize costs of integration of the projects as well as individual modules. The article contains an experiment of translating UML-diagrams from open source projects (github) to the OWL-ontology as well as the analysis of the frequency of the use of class diagrams elements. Moreover, the article presents the results of checking the consistency of the ontologies generated and offers the further ways of this direction development. This article is intended for IT professionals and experts in ontological modeling.

The Development of the Algorithm for Calibration and Temperaturehumidity Compensation of the Gas Sensor Readout on the Basis of the Stannic Oxide 000_14.pdf

The distinctive features of sensors on the basis the stannic oxide are high sensitivity, simple structure and the relatively low price. The main disadvantage of the sensors is the poor selectivity. Within the research, the gas sensor on the basis of the stannic oxide as a typical representative of the adsorption type sensors is chosen. The article discusses the calibration and improvement in the accuracy of gas sensors on the basis of the stannic oxide that are widely used in systems designated for the gaseous atmosphere composition control. The algorithms for calibration and temperature-humidity compensation of the gas sensor readout are developed. The algorithms allow to calibrate these sensors without using the complex equipment as well as to correct their readout depending on the temperature and humidity of the environment. The developed algorithms increase the readout accuracy of the sensor on the basis the stannic oxide. The proposed solutions are based on well-known approaches to sensor calibration and correction. The solutions also concretize the results relating to the MQ-13type of sensor.
