Published: December 2023

An approach is presented to employ two different types of converters in bridgeless configuration for supply side power factor enhancement of the system. The isolated single‐stage electric vehicle battery charger uses two different converters in a bridgeless configuration to extract the advantages of both converters for supply‐side power factor enhancement. For the negative and positive semi‐cycles of the supply voltage, the power factor‐enhanced asymmetrical alternating current–direct current converter utilises a fourth order single‐ended primary‐inductor converter and a second order buck‐boost converter, respectively. The use of single‐ended primary‐inductor converter and buck‐boost converter in bridgeless configuration reduces the net order of the system with respect to conventional bridgeless‐single‐ended primary‐inductor converter schemes. The buck‐boost converter also needs the supply‐side filter to eradicate the unwanted harmonics in the supply current which increases the order of the system. The usage of both converters presents many benefits like input inductance of the single‐ended primary‐inductor converter can be utilised as a filtering element with a capacitor for the buck‐boost converter. The anti‐parallel diode conduction operation of both switches facilitates the elimination of extra reverse feed diodes (generally used in bridgeless schemes). The single‐stage charger itself comes with the benefit of elimination of extra stages and thus the losses associated with it. The presented charger also witnesses the elimination of the rectifier due to usage of bridgeless configuration. The isolated single‐stage electric vehicle battery charger is also garnished with electrical isolation which adds to the safety standard of the system. To attain power factor enhancement, the asymmetrical alternating current–direct current converter functions in discontinuous current conduction mode in the present work. The elimination of extra‐stages (with respect to two stage charger), a filter, a rectifier, two extra reverse‐feeding diodes, one voltage sensor, one current sensor (with respect to continuous current conduction mode), and electrical isolation not only makes the system compact and safer but also makes the system cheaper. Elaborated mathematical modelling and stability analysis of the presented alternating current–direct current converter using a pole‐zero map and bode plot have been included in the article. The prototype and MATLAB/Simulink model of isolated single‐stage electric vehicle battery charger system with discontinuous current conduction mode control has been built and results of both prototype and MATLAB/Simulink are deployed to verify isolated single‐stage electric vehicle battery charger system's performance during dynamic and steady‐state conditions.

Massive, starbursting galaxies in the early Universe represent some of the most extreme objects in the study of galaxy evolution. One such source is HFLS3 (z ∼ 6.34), which was originally identified as an extreme starburst galaxy with mild gravitational magnification (μ ∼ 2.2). Here, we present new observations of HFLS3 with the JWST/NIRSpec integral field unit in both low (PRISM/CLEAR; R ∼ 100) and high spectral resolution (G395H/290LP; R ∼ 2700), with high spatial resolution (∼0.1″) and sensitivity. Using a combination of the NIRSpec data and a new lensing model with accurate spectroscopic redshifts, we find that the 3″ × 3″ field is crowded, with a lensed arc (C, z = 6.3425 ± 0.0002), two galaxies to the south (S1 and S2, z = 6.3592 ± 0.0001), two galaxies to the west (W1, z = 6.3550 ± 0.0001; W2, z = 6.3628 ± 0.0001), and two low-redshift interlopers (G1, z = 3.4806 ± 0.0001; G2, z = 2.00 ± 0.01). We present spectral fits and morpho-kinematic maps for each bright emission line (e.g. [OIII]λ5007, Hα, and [NII]λ6584) from the R2700 data for all sources except G2 (whose spectral lines fall outside the observed wavelengths of the R2700 data). From a line ratio analysis, we find that the galaxies in component C are likely powered by star formation, though we cannot rule out or confirm the presence of active galactic nuclei in the other high-redshift sources. We performed gravitational lens modelling, finding evidence for a two-source composition of the lensed central object and a magnification factor (μ = 2.1 − 2.4) comparable to findings of previous work. The projected distances and velocity offsets of each galaxy suggest that they will merge within the next ∼1 Gyr. Finally, we examined the dust extinction-corrected SFRHα of each z > 6 source, finding that the total star formation (510 ± 140 M⊙ yr−1, magnification-corrected) is distributed across the six z ∼ 6.34 − 6.36 objects over a region of diameter ∼11 kpc. Altogether, this suggests that HFLS3 is not a single starburst galaxy, but instead a merging system of star-forming galaxies in the epoch of reionisation.
Detection of decayless oscillations in solar transition region loops
Authors: Gao Yuhang , Hou Zhenyong , Van Doorsselaere Tom , Guo Mingzhe
Published: December 2023

Context. Decayless kink oscillations have been frequently observed in coronal loops, serving as a valuable diagnostic tool for the coronal magnetic field. Such oscillations have never before been reported in low-lying loops of the transition region (TR).

Aims. The aim of this study is to detect decayless kink oscillations in TR loops for the first time.

Methods. We used the SI IV 1400 Å imaging data obtained from the Interface Region Imaging Spectrograph. We applied the Multiscale Gaussian Normalization method to highlight the TR loops, and generated time–distance maps to analyse the oscillation signals.

Results. Seven oscillation events detected here exhibit a small but sustained displacement amplitude (0.04–0.10 Mm) for more than three cycles. Their periods range from 3 to 5 min. The phase speed is found to increase with loop length, which is consistent with the decrease in Alfvén speed with height. With these newly detected oscillations, we obtain a rough estimate of the magnetic field in the transition region, which is about 5–10 G.

Conclusions. Our results further reveal the ubiquity of decayless kink oscillations in the solar atmosphere. These oscillations in TR loops have the potential to be a diagnostic tool for the TR magnetic field.

Published: December 2023

This article highlights scientific approaches to solving problems that arise in the development of models for optimal control of multi-parameter technological processes. In particular, at the modeling specification stage, the necessity of developing artificial intelligence algorithms aimed at creating derivative parameters and ensuring their effectiveness for the optimal parametric and structural formulation of the problem is revealed. It is justified that the creation of neural rules is a relatively simple process in improving the formal model of complex systems using combinatorial derivatives of the relationships of significant elements over the full range. Usually, in the modeling of sufficiently complex, multi-parameter, uncertain technological systems, it is impossible to fully cover all the elements of the system that can have a strong influence on its reaction. There are several reasons for this. Nevertheless, the main scientific idea of the research is that it is possible to develop mathematical models that preserve the general effect of all elements and allow for its multi-level assessment, which are tasked with making management decisions.

The main purpose of the work is mathematical modeling of the sequence of technological operations performed by trains at stations. Methods of systematic analysis, analytical, regression and graphic modeling, flow mapping of the sequence of technological actions were used. The methods of normalizing the time of stay of trains at stations and their advantages, the degree of interconnections and disadvantages of technological actions were studied. At the station, the time spent on the technological actions performed with the train was analyzed and the factors that negatively affect their execution were determined. In order to increase the level of execution of station performance indicators, it was recommended that the method of basic normalization of the time for performing technological actions with shunting and train locomotives depends on the length of the half-trip, the number of connecting and disconnecting wagons and the speed of the shunting. This method allows you to analyze the indicators of the time spent on technological actions at stations and the graph of train traffic (GTT), as well as increase the carrying capacity of rail transport by 7-11%.

Authors: Kim K.K. , Titova T.S. , Krasnov A.S.
Published: December 2023

One of the main tasks of recent years is the development of the Arctic region of Russia. This is due to the economic, political and defense interests of the country. The Arctic zone is characterized by harsh climatic conditions and, as a consequence, high consumption of energy resources to ensure uninterrupted operation of heat supply systems. Taking into account the fact that fuel oil, supplied from other regions, is used as the main type of fuel, the issue of energy efficiency of heat supply systems is quite acute. The proposed methodology for assessing energy efficiency is based on several mathematical methods, including the method of correlation analysis, the method of ranking of indicators and the method of expert criterion evaluation. Generalization of these methods as applied to the heat supply system allowed to create a methodology of criteria assessment of energy efficiency of heat supply systems, allowing with minimal time and with high accuracy to evaluate the effectiveness of the entire system and its individual components. In addition, the application of criteria assessment makes it possible to determine the most relevant areas of energy saving of heat supply systems and to assess the technical and economic effect from the implementation of a particular energy saving measure, taking into account a wide range of external factors and the characteristics of specific heat supply systems.

Published: December 2023

The integration of power plants based on renewable energy sources (RES) into existing energy systems causes a number of problems, one of which is the violation of the stability of the generators parallel operation. One of the possible methods for the above problem solving is the use of virtual inertia systems (VIS). In this paper, we review the process of a converter developing for further use in a VIS prototype. The developed device converts direct current from a laboratory power supply into a sinusoidal three-phase voltage of industrial frequency. The switching of the converter’s power transistors is controlled through digital signal processor (DSP) TMS 320 F 28379 D via IR 2110 drivers. Using Altium Designer, a schematic diagram and layout of the printed circuit board of the converter were developed. Based on the manufactured printed circuit board, a converter was assembled, the correctness of its operation was checked, and a conclusion was made about the possibility of its use in the VIS prototype.

Published: December 2023

The article analyses the volume of electricity production in Russia at solar and wind power plants. The conducted studies allowed the authors to assess the potential for reducing carbon dioxide (СО2) emissions by using these renewable energy sources. The role of renewable energy in the energy supply of Russian regions and in the reduction of СО2 emissions is assessed. The regions of Russia were ranked by the level of decarbonisation due to use of renewable energy sources, and there was assessed the role of renewable energy in the energy balances of the country’s regions. In 2023 due to the operation of power facilities without the use of fossil fuels it is possible to avoid emissions of 4.75 million tons. The study revealed a positive trend in reducing СО2 emissions in all leading in RE regions of Russia from 2020 to 2030. According to the forecast using neural networks the total reduction in СО2 emissions due to the use of renewable energy sources in all the regions under consideration may amount to approximately 0.46% of the total СО2 emissions in Russia in 2022 by 2030. This shows not so significant prospects for renewable energy in terms of decarbonisation while maintaining the current place of increasing the capacity of their use in Russia. However, for some regions located in the Southern Federal District, the development of renewable energy sources is of great importance for improving the environmental situation and shows the need for further development and support of domestic technologies.

Authors: Chemagin Andrey , Drabovich Yuriy , Popova Elena
Published: December 2023

In this work, a study was made of the downstream migration of burbot larvae. To carry out the control catch, the larvae were trawled during the spring flood using a small motor boat. As a result of the work, it was found that the main factor affecting the number of larvae in the watercourse is the water temperature factor. Statistical analysis showed that more than 40% of the factors influencing the runoff of burbot larvae in the studied section of the river were taken into account. A mathematical model is proposed that reflects the dynamics of the number of larvae depending on the water temperature. It was shown that during the study period, with an increase in the level and temperature of the water, as well as the speed of the current, the number of larvae decreased from 0.7 to 0.005 ind./m3. The body length of the larva in the control catches ranged from 2.98 to 4.71 mm. Control fishing was carried out immediately after the river was opened from ice, the duration of the period during which migration continued was 10 days. Larvae were not recorded in trawl catches when the water temperature reached 6.53 ¼.

Rhizoctonia solani in addition to Fusarium oxysporum f. sp. ciceris have been recorded the most closely related fungi to root rotted as well as wilted chickpea plants assembled from various locations in Ismailia Governorate, Egypt. In the pathogenicity tests, all isolates were capable of infecting chickpea plants cv. Giza 2 and caused signs of root rot in addition to wilt diseases to variable degrees. The isolate of Rhizoctonia solani number 4 with accession No. (OR074128) and F. oxysporum isolate number 3 with accession No. (OR074126 ) were the more virulent ones. In the present study, abiotic substances viz hydroquinone, salicylic acid, benzoic acid, and chitosan were evaluated compared with Topsin M-70® fungicide for controlling these diseases under in vitro in addition to in vivo conditions. The application of abiotic substances demonstrated fungicidal action was inhibited the mycelia outgrowth of the two examined fungi by varying degrees. Chitosan was the greatest efficacy accompanied by hydroquinone and salicylic acid. In the pots and field experiments, all treatments significantly decreased root rot in addition to wilt diseases incidence consequently raised the number of survival plants. The highest protection from the infection of both the tested pathogenic fungi occurred under chitosan treatment followed by hydroquinone and salicylic acid. showed the best increase over the control, hydroquinone came next followed by salicylic acid. In physiological aspects, the activities of defense-related enzymes, exactly (peroxidase “PO”, polyphenol oxidase “PPO”, total phenol content “TPC”) and photosynthetic pigments enhanced in all abiotic substances applications as contrasted with untreated inoculated plants in addition to untreated uninoculated plants.

From the agrochemical properties of soils, their nutritional regime is of great importance. Since, plant nutrition is associated with it. In serozem-meadow soils, the nitrogen regime is in the most vulnerable position. Since the content of ammonium and nitrate nitrogen in the soil is at a minimum. The introduction of nitrogen fertilizers improving the nitrogen regime of the soil has a positive effect on the growth, development and accumulation of amaranth grain yield. The most optimal fertilizer nitrogen rate was 250 kg / ha against the background of P150K200 (1-experiment), an increase in the nitrogen fertilizer rate to 300 kg / ha against this background did not significantly increase the yield of amaranth grain. The study of the norms of mineral fertilizers without applying manure and in combination with it showed that mineral fertilizers (NPK) and manure at a dose of 30 t / ha significantly improve the poor nutritional regime of serozem-meadow soils, creating a high level of nutrition for amaranth plants. At the same time, the highest level of the nutrient regime of the soil was observed with the combined application of mineral fertilizers with manure. The highest yield was obtained on the N200P140K100 +30 t / ha option.
