Product quality testing should be effective. It is necessary to minimize the risks of making erroneous decisions. During testing, errors of the 1-st kind (a suitable product is rejected) and the 2-nd kind (an unsuitable product is mistakenly accepted) can occur. Quality indicators of mass-produced products testing are the risks for customers and manufacturers. The risks assessment accuracy depends on several factors. It is proposed to use the upper confidence limits of the indicated risks when developing and certifying control methods. It was proposed to find these confidence limits and requirements for the measurement accuracy during control by the Monte Carlo method. The advantage of this method is the ability to obtain numerical results without performing a physical experiment or complex analytical calculations. Quantitative estimates of desired risks of making erroneous decisions when testing electric meters are obtained. Due to this method, it is possible to investigate the dependence of these risks on the volume of the products controlled sample considering the measurement results uncertainty. The method also allows the reasonable establishment of “control” tolerances to ensure the test results required validity.

The paper is devoted to strain-sensing properties of biopolymer composite film materials based on chitosan matrix with few-layered graphene as electrically conductive filler particles. The composite films were made by flow-coating method of colloidal dispersions of few-layered graphene in solution of chitosan in water and lactic acid with polyvinylpyrrolidone or pluronic F108 as surfactants. The experimental samples about 70–100 µm in thickness were made with few-layered graphene content of 3% and 4% (wt.) for the composites with polyvinylpyrrolidone and 2 %, 3 %, 4 % and 5% (wt.) with pluronic F108. Electrical resistivity changed from 0.016 to 1300 Ohm-m depending on surfactant and few-layered graphene content. The samples were shown to have strain-sensing properties, the strain gauge factor to be from 1.3 to 5.7 depending on the filler content and surfactant used. The strain-sensing properties were studied with beams of uniform strength (in bending), the composites bonded to them with cyanoacrylate glue. The composites are perspective as strain gauges for health monitoring due to their biocompatibility.

A fiber-optic transmission system for multi-level pulse amplitude modulated signals with direct photodetection on the receiving side is considered. A mathematical model for the transmission of M-level PAM signals through the dispersion optical path based on the Gaussian approximation of the transmitted pulses has been developed. The criterion of the noise immunity evaluation is the narrowing of the eye closure in the receiver. Formulas that allow estimating the power penalty due to fiber dispersion, depending on the levels, duration and duty cycle of optical pulses, as well as the parameters of the optical fiber are derived. Comparative estimates of the noise immunity of transmission PAM −4 and PAM-2 signals with bit rates of 12.5 Gbps, 25 Gbps, 50 Gbps, 100 Gbps, 200 Gbps, 400 Gbps over a standard optical fiber at a wavelength of 1550 nm are given. In comparison with the transmission of PAM-2 signals, the use of PAM-4 signals is preferable at a signal transmission rate of more than 25 Gbit/s and power penalties of more than 2.5 dB, provided that the bit error correction technology is used in the transceiver equipment, which halves the bandwidth requirements for optoelectronic components.

The widespread use of renewable energy sources has led to a slight decrease in a demand for thermal coal and, as a result, in the profitability of underground coal mining. In this regard, increasing the energy efficiency of the electrical complex of a coal mine becomes especially important. One of the ways to improve energy efficiency is to install reactive power compensation devices. However, due to preliminary studies of the process of reactive power consumption, there are no recommendations on the choice of the number of control steps for high-voltage explosion-proof mine capacitor units. This article is devoted to the study of the optimal arranging of the EPMCU for power factor correction of the longwall shearer of a coal mine. The assessment of the nature of the electric load of the shearer was carried out on the basis of a large amount of current load measurements. Analytical and optimization methods were used to select the power of the EPMCU steps. It is shown that the use of step compensating devices makes it possible to increase the efficiency of for power factor correction.

In the paper DC low-noise amplifier based on commercial silicon SSM2212 transistors and operating at 77 K are described. The amplifier circuit is a differential stage with one of the arms grounded. Its characteristics, depending on the amplifier operating current, are measured. The schemes for measuring the main parameters of the amplifier are described and the following characteristics are obtained: transfer function, input voltage and current noise densities (less than 0.4 nV/Hz1/2 and about 5 pA/Hz1/2 at 10 kHz, respectively). For the voltage noise, the flicker noise threshold frequency is increased to 20 Hz at 77 K. Based on the results obtained, the amplifier input resistance and some parameters of the bipolar transistor hybrid-π noise model are estimated. In addition, the optimal resistance of the signal source is estimated to obtain the minimum noise figure. The obtained results have shown the suitability of commercially available bipolar transistors for cryogenic applications and could be used to optimize a custom readout system using a cryogenic amplifier based on this type of bipolar transistor.

Profiling website visitors is necessary to better tailor the features that affect the overall user experience and ultimately achieve higher customer satisfaction. Our paper considers the usage of such dimensions of visual impression as Complexity, Aesthetics and Orderliness to identify statistically differing user groups. The analysis is based on the experiment with 70 participants of different demographics and professional occupations who evaluated 497 university websites. The results suggest that the profiling of visitors should be specific to the website goals. For instance Complexity impression was not affected by the gender factor, but business and technical specialists did evaluate it differently. Moreover, the latter groups of specialists also associated higher Complexity with lower Aesthetics, whereas the other groups in the study, including the students, thought otherwise. We also demonstrated that the demarcating age value was 19, after which the visual preferences seemed to change dramatically. The results of our study might be useful for both theoreticians working in human-computer interaction and to practicing website designers and user researchers.

The problem of non-disturbing diagnostics of the phase and temperature fields of the reacting jets and flames is solved in the work. On the example of an axisymmetric hydrogen-diffusion flame, a method was developed, based on Hilbert polychromatic visualization of phase optical density fields, and measuring the temperature profile in selected areas of the medium under study. The diagnostic complex is implemented on the basis of the IAB-451 device. The visualized diffusion flame in the axial symmetry approximation is analyzed using the Abel transform. The reconstruction of the temperature field is carried out considering the diversity of the partial optical properties of the gas mixture in a model consistent with the Gladstone-Dale dispersion formula. The influence of disturbances in the air surrounding the flame on its axial symmetry is discussed. The criterion for the reliability of the research results is a comparison of the hilbertograms obtained in the experiment and the reconstructed hilbertograms.

Uncertainty of estimating the parameters of the aircraft compartments heat exchange mathematical model requires the use of a joint confidence region for estimating the model parameters. The joint confidence regions of parameter estimates describe in the model parameter space the r- dimensional ellipsoid with the center in the vector of the model parameters actual values, where $r$ is the number of model parameters. In the case of a large dimension of the parameter vector, the use of the joint confidence region is associated with computational difficulties. Therefore, conditional joint confidence intervals of each required parameters are introduced in the form of projections of the joint confidence region on the corresponding coordinate axes of the parameter space, which is equivalent to replacing the elliptical region by the parallelepiped circumscribed around it. In recent two or three decades, with the emergence of a powerful supercomputer technology, new possibilities for the numerical solution of the time-consuming tasks, including multidimensional ones, have opened up. Due to the fact that the Monte-Carlo methods are parallelized with a good measure of effectiveness and compared with other methods they are far less sensitive by labor intensity to the dimension of problems increase, they become more competitive. In particular, multi-dimensional problems for parabolic equations on the basis of probabilistic concepts of their decisions can be solved by the method of statistical modeling. Among other things, it is possible to solve inverse problems of the thermal state of the aircraft fuselage honeycomb core and grid constructions using the parabolic boundary value problem with discontinuous coefficients basing on the numerical solution of stochastic differential equations with the use of derivatives assessments on the expected functional parameters of the diffusion processes.

Image processing is widely used in many fields, including electronics, computer science, energy, construction, medicine, and self-driving cars. Deep learning based object detection methods have also evolved to detect in real-time. Depending on the nature of the object or image to be processed, the performance of image processing methods will vary from application to application. Therefore, researchers test different types of algorithms in each case and compare performance results. The study aims to detect and report selected objects, such as insulators and vibration dampers. This video was recorded by using an UAV in a power transmission line. The research aims to identify the insulator from the input data processed by image processing, create an image database, and then report the visible physical damages. This study summarizes the results of a study in which video insulators and vibration dampers were detected using the DL youonly look once algorithm.

Multimode microwave resonators with a rectangular strip conductor split at one end and grounded to the base at the opposite end, as well as ultra-wideband bandpass filters based on them, were studied by means of numerical electrodynamic analysis of their three-dimensional microstrip models. When calculating amplitude-frequency characteristics of all microwave devices, monolithic substrates with a high dielectric constant $varepsilon=80$ (microwave material - TBNS ceramics) were used. It is shown that in multimode resonator, the folding of a strip conductor in the form of a meander is accompanied by additional resonances to its passband. It is possible to organize an additional channel of power passage in the considered resonators, which significantly improves their selective properties. There is also a possibility to implement ultra-wideband bandpass filters with a relative bandwidth of at least 100% based on the proposed multimode microstrip resonators. Filters can be designed using both one resonator and several counter-directional resonators in the device. All synthesized microwave structures are given with constructive dimensions.

When calculating amplitude-frequency characteristics of all microwave devices, monolithic substrates with a high dielectric constant $varepsilon=80$ (microwave material - TBNS ceramics) were used. It is shown that in multimode resonator, the folding of a strip conductor in the form of a meander is accompanied by additional resonances to its passband. It is possible to organize an additional channel of power passage in the considered resonators, which significantly improves their selective properties. There is also a possibility to implement ultra-wideband bandpass filters with a relative bandwidth of at least 100% based on the proposed multimode microstrip resonators. Filters can be designed using both one resonator and several counter-directional resonators in the device. All synthesized microwave structures are given with constructive dimensions.","PeriodicalId":272064,"journal":{"name":"2021 XV International Scientific-Technical Conference on Actual Problems Of Electronic Instrument Engineering (APEIE)","volume":"92 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-11-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122533182","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
