A METHOD OF CONTACTLESS MEASUREMENT OF SURFACE TEMPERATURE OF RADIO ELECTRONIC OBJECTS 18 Annotation:There exists quite an extensive bibliography on the methods of contactless measurement of temperature of the surfaces of objects. However, very few works have been devoted to studying the pyrometry of temperatures not exceeding 700 K, though these are badly needed for practical application in radio electronics, medicine, construction and other fields of science and technology. The market of modern measuring devices has plenty of domestic and foreignmade optoelectronic systems (OESs) which can be used for these purposes. However, the results obtained with the help of modern OESs in most cases need to be thoroughly analysed, for sometimes they may appear to be wrong. Most often errors occur due to unaccounted or incorrect account of spectral dependence of OES characteristics, opticophysical parameters of the object under control and its background. A procedure for the pyrometry of objects (pyrometers, thermal imagers), using OESs, is proposed, which includes planar arrangement within the view of OES of the object under investigation, the normal spectral emissivity of the surface of which is known, and a reference transmitter, the normal spectral emissivity of which is also known, and its temperature is controlled and measured. A mathematical model of the process is suggested for the mode when full heat flows of the object and the reference transmitter are equal, allowing to define the target temperature value of the object surface. Applying the method of small perturbations, a metrological analysis is made of the proposed method for determining of the temperature of the object with the use of a monochromatic OES. The method of small perturbations can be described as follows: first, based on the selected values of the parameters, using the corresponding formula, calculation is made of the value of the sought quantity. Then, the value of only one of the parameters used in the calculation is changed for the value of its measurement error, and a new calculation is made of the target value. The deviation of the obtained value from the original value characterizes the impact of inaccurate knowledge of the variable parameter on the target value. The table gives the results of calculations of wavelengths of 0.50, 2.0, 5.0, 8.0, 14 and 50 microns; of temperatures of 400, 700 and 1000 K; of normal spectral emissivity of the object of 0.1, 0.5 and 0.9; of the background temperature of 300 K; of normal spectral background emissivity of 0.5 and reference emitter of 0.98. It can be seen that a comprehensive analysis of the process of temperature measurement, the main information parameter of both the technological process of the manufacturing of objects and their thermal condition at all stages of the life-cycle, should precede both the measurement of the object surface temperature, and also the selection procedure of OES for its realization. Only obtained in this way the results can be considered reliable with the determined real measurement error.Keywords: test bench, integrated circuit chip, characteristics, algorithm, charge pump, control program, virtual panel.Keywords: pyrometry method, assurance of measuring devices, contactless measurement of temperature, object surface, method of small disturbances/perturbations, error, monochromatic optico-electronic systems, calculation results, basic information parameter, credibility of measurement results. |

TRAVELING-WAVE ANTENNA WITH A REDUCED LEVEL OF SIDE LOBES DUE TO VARIABLE PHASE VELOCITY 8 Annotation:One of the main parameters that characterize the quality of the antenna side lobe level is that in some cases should be the lowest possible with minimum dimensions of the antenna. The aim of this work is to find a method for reducing the side lobe level at constant mass-dimensional parameters of the antenna. The study has found a link between the distribution function of the deceleration phase velocity along the traveling wave antenna and the level of the side lobe. In particular, it was found that under certain laws of the phase velocity changes along the antenna, the level of the side lobe can be reduced significantly. As a result of numerical analysis of directional antennas traveling wave chart with slow phase velocity varying sinusoidally, revealed a decrease in the level of the first and second side lobes 1.5 ... 3 times as compared with the conventional optimum traveling wave antenna. Despite the reduction in the emission side, directional factor is the same as that of a conventional antenna of a traveling wave with a constant phase velocity of the same length.Keywords:antennas, radiation pattern, directional ratio, the level of the side lobe, sinusoidal law. |

MONOLITHIC INTEGRATED CIRCUIT OF GаN LOW-NOISE AMPLIFIER FOR 57–64 GHz BANDWIDTH 15 Annotation:The article describes the development of a low-noise amplifier for the 57-64 GHz band based on a wide-gap semiconductor – gallium nitride. We analyze existing commercial developments in the area of low-noise amplifiers for the 60 GHz band, which are based mainly on gallium arsenide. At the initial stage we developed test HEMT-transistors on the basis of which we created the transistor models – Fujii model and Pospieszalski model. On the basis of the developed models we designed an amplifier schematic circuit consisting of 4 cascades. Based on the schematic circuit, we designed a topology of a monolithic integrated circuit in the ADS CAD, and made a complete electrodynamic calculation of the topology, which showed reachability of the required characteristics in the frequency range 57-64 GHz. Conducted measurements of a manufactured sample showed the fulfillment requirements of the range and a good agreement with the calculations. One of the features of the technology of the developed amplifier is the step of forming of electrical connections - through holes, which provide a common grounding plane of the circuit.Keywords:monolithic integrated circuit, millimeter wave, low-noise amplifier, HEMT, noise figure, AlGaN/GaN heterostructure. |

Annotation:The article presents the analysis of domestic and foreign engineers training experience.
Current problems the Russian Federation Higher Technical Education has faced are specialized
as well as practical recommendations for engineering education quality improvement are
proposed. It has been concluded that our country science and technology manpower regeneration
should become one of the most important strategic directions amid the recovery from crisis,
technological breakthrough and acceleration of modernization rate necessity.
It is claimed that rather often technical university graduates lack in both knowledge of innovative
technologies and adequate experience in research work. The authors consider that the main reasons of
graduates low-level competency are the result of inadequate education requirements at school, lack
of Higher education financing and specialist’s to bachelor’s programmes’ transformation. Keywords:engineering education, higher technical school, education quality, bachelor's degree programme, master's degree programme. |

EFFECT OF INTERNATIONAL TECHNOLOGICAL DIFFERENTIATION OF LABOUR ON ECOLOGICAL AND INDUSTRIAL SAFETY 9 Annotation:At present, an international division of labor, as a rule, does not take into account neither the climatic specifics of the territory nor socio-cultural characteristics of natural resources of the local population. The possibility of such a division of labor within the framework of liberal theory of economics is proved by the concept of "comparative costs", according to which the role of each country in the international division of labor should be determined by its ability to produce a product with economic costs that are less than in other countries. This concept does not allow to organize environmentally friendly use of resources of the biosphere as a holistic natural body, what leads to an increase in environmental problems, not only in those countries, which are diverted with the status of the environmental colonies. Taking into consideration that, in a globalized economy, there exists the interdependence of countries in the field of environmental and industrial safety, the authors propose to use the institution of "natural sovereignty" in an international investment policy. Within the framework of the proposed institute, each state should build a policy of natural resources, taking into account both ecological and economic interests of its people and those general biosphere limits that guarantee the liveability of the biosphere for the world community as a whole. The institution of "natural sovereignty", according to the authors, will serve as the basis for the formation of the responsibility of each state for the environmentally safe development of both its country and the entire world community. At the same time, the adoption of this concept will require the formation of outlook sharing the conviction that the biosphere exists in the system of natural planetary dependencies, the breach of which leads to the destruction of its livability and the death of civilization.Keywords: globalization, international division of labor, environmental safety, industrial safety. |
