Optimal Creation of Control Loops 54_1.pdf

The creation process of control loops in a hierarchical automated control system is determined by a three-dimensional task of optimal distribution of control objects, monitoring software, and environment objects. Different variations of control loops are presented. An algorithm of random searching the optimal distribution of two-dimensional task with control objects and environment objects is described. The analytical approximation of algorithm is given. It was obtained by the orthogonal transformation and was implemented while planning the control objects usage with regard to changing their location in space. Based on the algorithm of the two-dimensional task distribution, the algorithm of random searching the optimal distribution of three-dimensional task for one of the variations when each loop was created by the specified elements that are not included in other loops was developed. Following the results of the undertaken analysis, it was found that task time at high dimensionality could not comply with the dynamic of situation changing. The way of applying the analytical dependence for task time reducing is shown as well as the corresponding algorithm is described. The findings of experimental studies carried out by the use of the developed software are given. The obtained results verify the theory.

Changing the Lighting in the Scenes By Using Neural Networks Cascades 54_7.pdf

The article describes the process of creating the artificial illumination of surfaces taking into account shadows on convex and concave surfaces using machine learning algorithms and methods of working with three-dimensional objects.Despite the variety of applications for photo processing (LightRoom, Photoshop, Snapchat, Instagram etc.), there is a problem associated with the correct modeling of lighting on surfaces, due to the peculiarity of the photo format. First, the photo is a two-dimensional object and contains only indirect information about three-dimensional objects depicted on it. Secondly, the photoimage captures a certain state of objects with a certain set of properties, which are not enough for modeling shadows and lighting. The missing information is difficult to recreate by classical algorithms or heuristics because of the large number of parameters for recognition of objects in the photo and their possible combinations. However, machine learning algorithms are able to approximate very complex functional relationships based on training samples. This article describes the solution to the problem of modeling artificial lighting and shadows in photography using several neural networks trained on synthetic data.

Numerical Aspects of Far-end Crosstalk Cancellation in Vdsl Downstream 54_9.pdf

A complexity analysis of computations involved in two precoding methods - Zero Forcing (ZF) vs. a Simplified Linear (SL) - in the context of a Very high-speed Digital Subscriber Line (VDSL) is presented in this paper. For the ZF-precoding technique, eight computing strategies have been compared, four of which entail the explicit calculation of inverse normalized channel matrices and other four do not. In addition to this analysis, SL-precoder complexity - based on the approximate matrix inversion-has been estimated. Both methods solve the problem of full or partial far-end crosstalk (FEXT) cancellation in VDSL downstream transmission. For this problem, the strategy avoiding the explicit matrix inversion was found to have the smallest number of multiplication/division operations. The analysis performed provides an opportunity for VDSL-designers to justifiably select a computationally attractive precoding strategy taking into account the necessity of adaptive power control for the input signals to the DSL-channel from the Central Station.

Mathematical Modeling and Numerical Analysis of Thermal Protection Effectiveness With Hemispherical Damping Cavities 54_10.pdf

The gas turbine engine performance improvement is linked inextricably with the increase of the intensity of dynamic, aeromechanical and thermal processes, which, in turn, requires the development of systems and devices allowing to protect the most loaded equipment components. The most effective ways to protect surfaces from overheating are a convective cooling; the absorption and accumulation of heat by condensed substances; the cooling that operates on mass transfer principle; the radiation and electromagnetic cooling; heat-shielding coatings. One of the most effective ways to protect surfaces from overheating is a thermal protection in the form of film-like surface cooling based on the mass-transfer surface-cooling principle. This method is widely distributed and it proved to be effective. The paper considers the possibility of improving this method of cooling due to the impact on the boundary layer with hemispherical damping cavities behind the injection section of the cooler. A mathematical model is proposed, the numerical study of the thermal protection effectiveness by the use of hemispherical damping cavities is carried out. The possibility of a significant decrease of the turbulent heat exchange in the boundary layer and of the efficiency improvement of the thermal surface protection of ? by0.06 due to the use of hemispherical damping cavities has been established. The proposed method of thermal protection intensifying and numerical analysis of its efficiency will improve the gas turbine engines that are available for different applications of domestic industry for example in power generation sector, aircraft engineering as well as in shipbuilding.

Developing the Model for Improving the Vehicles’ Operating Characteristics 54_11.pdf

The process of developing the model to improve vehicles’ operating characteristics has been described in the article. The model development is based on the interrelation and reciprocal influence of the main elements of the vehicle. Since the internal combustion engine is the source of energy and the driving force, its characteristics has a direct influence on the operating properties of the vehicle. In its turn, they mainly depend on the nature of the working process course and engine parameters. Therefore, a change in the technical and operational characteristics of the engine will entail a change in the operating characteristics of the vehicle in which it has been installed. The information model of the engine parameters’ influence on operating characteristics of the vehicle allows us to find that, for certain operating time and fixed values of operating modes, an improvement of operating characteristics of the vehicle can be made by changing the technical and operational characteristics of the engine. At the same time, considering the operating model of the internal combustion engine in a form of a specific multidimensional and multilevel system, it was found that the working process in the engine and the design parameters of its mechanisms have the greatest influence on the change in engine parameters. The main work process takes place in the engine cylinder, so the parts of the cylinder-piston group will have the greatest influence on the change in the output parameters of the engine. The use of mathematical modeling in solving this problem allows us to develop a concept of improving the vehicle’s operating characteristics, to optimize the process of choosing the ways to modernize the engine and the vehicle.

A System of Monitoring the Individual Absorbed Doses of Ionizing Radiation Based on a Gafchromic EBT3 Radiochrome Film 54_12.pdf

A system for monitoring the absorbed dose of ionizing radiation containing a personal dosimeter of the absorbed dose and a reader (system of readers) is proposed. The sensor material of the dosimeter is a Gafchromic EBT3 photochromic film, sensitive to both X-ray and gamma radiation. An original detector design containing an LED, two photodetectors located in one plane, and an optical flux divider with a mirror coating is proposed. Above one of the photoreceivers, a sensory element is placed, the change in optical transparency of which carries information about the absorbed dose. To transmit data on the measured dose, the radio channel and RFID technology are used. As readers of the data on the accumulated dose, mobile, desktop and stationary RFID readers can be used, including those integrated into enterprise information systems. The sensor used in the personal dosimeter makes it possible to measure the absorbed dose continuously for a long period of time. In addition, the dosimeter does not contain a power source, and the energy necessary for operation comes at the moments of interaction of the personal dosimeter with the reader, which ensures a reduction in the mass-dimensions and the possibility of implementing the dosimeter in a compact form factor.The results of model calculations and experimental studies carried out to justify the possibility of constructing a detector based on the Gafchromic EBT3 radiochromic film are presented.

Thermophysical Characteristics of Thin-film Electroluminescent Capacitors 54_13.pdf

Theoretical analysis and experimental studies of the processes of electric power dissipation and heating in thin-film electroluminescent capacitors in operating modes are carried out. The analysis of heat fluxes in a thin-film structure allowed to develop the thermal scheme of the electroluminescent capacitor. The calculation of numerical values of the thermal scheme elements taking into account features of properties of materials and designs of radiators is carried out. Studies have shown that the electrical power generated in the phosphor film in the form of heat is dissipated mainly through the glass substrate. It is established that the thermal resistance of a thin-film electroluminescent capacitor is 300-350 K/W and the thermal constant is 150-200 s. Heating of a thin-film structure does not exceed 10-15 K and cannot lead to degradation of the emitting indicator element.

Apparatus for Measurement of Thermal Impedance of Solar Batteries 54_14.pdf

This paper describes apparatus for measuring the thermal impedance of solar batteries. A modulation method that uses the harmonic heating power modulation is a base of the apparatus operation. This method allows to determine the thermal resistance components corresponding to the structural elements of a solar battery. To solve the problem, the post processing method for thermal impedance dependence on modulation frequency was developed.Apparatus provides a measurement range of thermal resistance from 0.01 to 100 K/W, the measurement error is 5%, the range of heating currents is from 0.25 up to 4 A, the range of heating power modulation frequency is 0.01 up to 1000 Hz.Research of thermal physical processes in solar batteries performed by the apparatus shows that thermal resistance dependence on heating current is non-linear. This is explained by the non-uniform current distribution through the junction due to the presence of positive thermal feedback.
