Environmental Control for Ensuring Cities Safety

By: Dmytro Gulevets,Artur Zaporozhets,Volodymyr Isaienko,Kateryna Babikova

This proceedings book is devoted to the development of environmental analysis of the surface layer of atmospheric air and green areas of urbanized areas. The analysis of scientific and methodological developments for assessing the level of environmental safety of urbanized areas, taking into account the influence of chemical and physical factors, is carried out. The choice of criteria for assessing the ecological state of the surface layer of atmospheric air is theoretically substantiated. The hazard index of the surface layer of atmospheric air, taking into account the influence of chemical and physical factors, and a method of its visual representation are proposed. An assessment of the environmental risk of the influence of the surface layer of the atmosphere was carried out. A quantitative assessment of the energy balance of the green zone is carried out for Kyiv city (Ukraine). Schemes for informing the population about the ecological state of air in real time are developed. The book is for researchers, engineers, as well as lecturers and postgraduates of higher education institutions dealing with issues of atmospheric pollution, ecological safety and urbanization.

Interactions Between Electromagnetic Field and Moving Conducting Strip

By: Ihor Kondratenko,Yuriy Vasetsky,Artur Zaporozhets

The book combines two interrelated lines of research. One of them is devoted to the development of the theory for solving a certain class of three-dimensional electromagnetic field problems of the three-dimensional electromagnetic field, taking into account eddy currents in a moving conducting magnetizing body. Preference is given to the development of the analytical solution methods of the three-dimensional quasi-stationary problem of field conjugation in the system: “a contour of an arbitrary spatial configuration with an alternating current is conducting body with a flat boundary surface”. The second direction refers to the development of mathematical models for solving applied problems, which involve the use of developed methods for calculating the electromagnetic field and their characteristics. The main application of calculation methods is aimed at solving problems of heat treatment non-ferrous and ferrous metal products using the induction method of heating in a transverse magnetic field. The inverse problems are solved to determine the inductor configuration as flat and spatial current contours for providing the necessary temperature distribution of moving metal strips. To achieve uniform heating of strips across the width using inductors in the form of flat current contours parallel to the strip surface, it is advisable to use combinations of current contours, where the geometric dimensions are determined by the size and electro-physical parameters of the metal strips. A more uniform temperature distribution during high-frequency induction heating is achieved by using inductors in the form of current contours of the required spatial configuration. The book is intended for researchers, postgraduate students, and students specialized in theory and calculations of electromagnetic fields and induction heating installations.

Electromagnetic Field Near Conducting Half-Space

Theory and Application Potentials

By: Yuriy Vasetsky,Artur Zaporozhets

The book is devoted to the solution of one general problem of the theory of a three-dimensional quasi-stationary sinusoidal and pulse electromagnetic field. These studies, unlike many well-known works, are based on obtained exact analytical solution of the problem for the field, generated by external current sources near the conducting body with plane surface. The solution for the vector and scalar potentials, electric and magnetic intensities in the dielectric and conducting media is found without restrictions on the configuration of current sources, properties of the media and field frequency. Some general properties of field formation for arbitrary field in the considered system are obtained (in particular, full compensation by the field of the electric charge distributed on the interface between the media, the normal component of the induced external electric field and, accordingly, the equality to zero the components both of the current density and the electric field intensity perpendicular to the interface; the non-uniform electromagnetic field decreases in depth of conducting medium faster than uniform field). It is shown that the exact analytical solution depends on the values of the parameter proportional to the ratio of the field penetration depth to the distance between the external field sources and the body. The concept of strong skin effect is extended to the case of small value of the introduced parameter. A significant simplification of the expressions was obtained as an asymptotic expansion on this small parameter. In the case of pulsed fields approximate method gives the highest accuracy during important initial period of pulse time. For asymptotic expansion the approximate impedance boundary condition is generalized to the diffusion of non-uniform field into conducting medium. The book is intended for the researchers, postgraduate students and students specialized in theory and calculations of electromagnetic fields.

Manufacturing Control of Textile Materials

Operational Computerized Non-contact Methods

By: Valerii Zdorenko,Nataliia Zashchepkina,Sergiy Barylko,Artur Zaporozhets,Serhii Lisovets,Ihor Kiva

This book examines issues of improving the efficiency of the control technological parameters of textile materials through with computerized systems with the application of non-contact methods as only they allow to react quickly to changes of technological parameters during production. The original models, algorithms, software and hardware of the developed system for the control technological parameters of textile materials are presented. Also, the book presents new methods for measuring the technological parameters of textile materials, which do not need require taking into account the constant readjustment of the system to controlled samples of materials with different structure and porosity. The developed model of the computerized system allows contactless control of basis weight and porosity of fabrics in the course of their production. This book contains six chapters, for researchers, engineers, as well as lecturers and postgraduates of higher education institutions dealing with ultrasonic control engineering equipment.

Control of Fuel Combustion in Boilers

By: Artur O. Zaporozhets

This book examines key issues in improving the efficiency of small and medium power boiler units by adding control systems for the fuel combustion process. The original models, algorithms, software and hardware of the system developed for controlling the fuel combustion process are presented. In turn, the book presents a methodology for assessing the influence of climatic factors on the combustion process, and proposes new methods for measuring the thermophysical characteristics, which require taking into account the concentration of oxygen in the air. The system developed here was implemented on a boiler of the NIISTU-5 type, which is widely used for heat power engineering in Ukraine and other Eastern European countries. Given its scope, the book offers a valuable asset for researchers and engineers, as well as lecturers and graduate students at higher education institutions dealing with heat engineering equipment.
