Authors: Majeed Hayder Q. , Ghazal Ali M. , Al-Hadeethi Basheer
Published: January 2023

Experimental and numerical studies have been conducted on the effects of bed roughness elements such as cubic and T-section elements that are regularly half-channel arrayed on one side of the river on turbulent flow characteristics and bed erosion downstream of the roughness elements. The experimental study has been done for two types of bed roughness elements (cubic and T-section shape) to study the effect of these elements on the velocity profile downstream the elements with respect to different water flow discharges and water depths. A comparison between the cubic and T-section artificial bed roughness showed that the velocity profile downstream the T-section increased in smooth side from the river and decrease in the rough side from it compared with the case when a cubic artificial bed roughness is used. By comparing the results for the element shapes, it can be notices that the T-section bed roughness element more effective compared to cubic shape for both sides of the channel. The numerical method has been done using Computational Fluid Dynamic (CFD) method. A validation for the CFD model with the experimental study have been carried out for a specific flow discharge and water depth. The results indicated that the velocity distribution profiles downstream the bed roughness elements in both sides shown very good agreement for manning coefficients between the numerical and experimental studies. The range of errors between the experimental and numerical study have been calculated using Root Mean Square Error (RMSE) approach, which is found that the RMSE is approximately equal to 1 in case of cubic bed roughness and the RMSE is about 1.5 in case of T-section bed roughness for both smooth and rough sides. Furthermore, the influence of the velocity profile and the bed erosion downstream of the T-section element under the effect of tides have been investigated using the CFD method, which is commonly happened in Shat al-Arab south of Iraq. The results show that the tide of the flow has a reverse effect on the velocity profiles for both sides. Since the velocity profile downstream of bed roughness region increase in the rough side and decrease in the smooth side compared with the normal flow of the river.

Published: January 2023

This contribution investigates the thermosolutal convection phenomenon around a thin wall, vertically immersed in a fluid saturating a porous medium of non-uniform permeability, taking into account the thermal conditions of the wall which is exposed to a fluid suction/injection. The conservation equations with boundary conditions have been transformed by the similarity method into a set of nonlinear differential equations. The resulting equations are numerically resolved using a fifth-order Runge-Kutta scheme coupled with the shooting technique. A graphical and physical interpretation of the found results as a function of the control parameters was performed. It is noticed that the heat transfer rate and the mass transfer rate at wall, are intensified for free convection and for significant permeability.

Published: January 2023

A model of a discrete system for stabilizing the ship's course has been developed and the results of research on the choice of an optimal digital controller for it are presented. The method of the describing function is used as a research method. In developing a mathematical model of a discrete system, a typical block diagram of a continuous stabilization system was used. The location of the quantizer and extrapolator in it was determined. The latter was selected as a zero-order extrapolator, as the simplest, easily implemented with standard equipment, although the use of a first-order extrapolator can give some advantage in the accuracy of information recovery. Modeling is carried out in state variables and in a classical way based on a discrete transfer function of stabilization system. For the research, the package of visual block simulation modeling of the MatLab matrix system was used. Modeling of the system of stabilization with different types of controllers allowed to carry out their comparative assessment. To improve the properties of the digital proportional integral derivative controller, it is proposed to introduce in it a correction system.
Representation of the Cardiomyocytes of the Heart Muscle in the Form of an Electrical Circuit Element
Authors: Melnikov Dmitrij
Published: January 2023

The article considers the simulation approach to describe the electrical functioning of the main heart muscle cell - cardiomyocyte, when instead of describing elements of different nature, whether electronic devices or biological objects, at the microphysical level of model ideas about the structure of matter, they are all considered from a single point of view in the sense that the nature of the application of these devices and objects is determined by the functions implemented at the available external inputs, while the degree of complexity of their internal structure has no significance for the operation of the system they belong to and whose operation is determined. A ferroelectric capacitor was chosen as a meaningful model for studying the mechanism of formation of electrical signals of the cardiomyocyte, because the mathematical description of its operation allows to model both nonlinearity and feedback of electrical processes occurring in the heart muscle. This model was mathematically formalized using the charge transfer equation in a nonlinear inertial system in the form of the balance equation, a delayed differential equation.

Authors: Tupitsyn Nikolay
Published: January 2023

A method for estimating of the required dimension net to capture drone is proposed. The results of calculations of the drone movement trajectories in horizontal and vertical planes depending on velocity and normal overload are presented. The calculation of the trajectories in the horizontal plane was carried out based on formula of the coordinated turn at constant values of a speed and normal overload. An analytical solution of the differential equation system for the isolated movement of the drone in the vertical plane is obtained. According to performed calculations, delivery of the net to the unwanted drone should be carried out with high-speed unmanned aerial vehicle in order to reduce the interception time and, accordingly, to reduce the required area of net for it capture.

This article is devoted to creation of the secondary network using base stations of mobile telecommunications operators. General advantages of the secondary networks are discussed. Then we suggest to build a novel network of low-cost small base radars (BSR) by adding the low-power radars to the existent selected base stations’ equipment. This gives a possibility to obtain a high-resolution meteorological information in particular about dangerous weather phenomena in real-time and for any region of mobile network coverage. The applications of the proposing network are not limited by meteorology, but includes also some other fields, for example, traffic monitoring, birds and insects’ migration observations, etc.
Vibratory Gyroscope Scale Factor and Bias on-Run Self-calibration
Authors: Chikovani Valeri , Golovach Serhii
Published: January 2023

А new method for on-run periodic scale factor and bias self-calibration of vibratory gyroscopes in an inertial measurement unit with a redundant number of sensors is proposed. Self-calibration uses predefined virtual positive and negative angle rates to calibrate the SF, and the bias of the gyroscope that is in calibration mode, while the others, at least three gyroscopes of an inertial measurement unit, whose sensitivity axes do not lie in the same plane, operate in the measurement mode to measure the real angle rate of a vehicle. The projection of the current angle rate onto the sensitivity axis of the gyroscope being calibrated is computed from the results of measuring the full angle rate vector by the other three gyroscopes, creating conditions for the calibration procedure. In contrast to known methods, such as single-axis or multi-axis rotation of an inertial measurement unit and vibration modes reversal, the proposed method does not use mechanical rotation, which requires additional devices, and does not require a reorientation of the vibrating wave, which entails the need to align the parameters of the two measuring channels. The scale factor and bias calibration procedure using this method is the same for any gyroscope of an inertial measurement unit and can be applied to several gyroscopes at the same time. Therefore, the proposed method has great potential for an application not only for small-sized 4-gyro inertial measurement unit based on vibratory gyroscopes but also for multi-gyro inertial measurement unit based on micro-electro-mechanical gyroscopes. Experimentally shown that using the proposed method a gyro requirements mitigation coefficient can be substantially increased and can provide high accuracy for autonomous navigation systems based on low-cost, small-sized, and micro-electro-mechanical gyroscopes.
Image Processing from Unmanned Aerial Vehicle Using Modified YOLO Detector
Authors: Sineglazov Victor , Kalmykov Vadym
Published: January 2023

Identifying objects from drone images is a state-of-the-art task for artificial neural networks. Since drones are always moving at different altitudes, the scale of the object varies greatly, making it difficult to optimize the networks. Moreover, flying at high speeds and low altitudes leads to blurred images of densely populated objects during movement, which is a problem when solving the problem of recognizing and classifying small sized objects. This paper addresses the above problem solutions and solves them by applying an additional prediction model to identify objects of different scales. We also modify the loss function to penalize larger objects more and vice versa to encourage recognition of smaller objects. To achieve improvements, we use advanced techniques such as multiscale testing, image blurring, object rotation, and data distortion. Experiments with a large data set show that our model has good performance in drone images. Compared to the baseline model (YOLOv5), our model shows significant improvements in object recognition and classification.

Delayed Fuel Consumption Optimization System
Authors: Mukhina Maryna , Nikulin Artem
Published: January 2023

In this work, we considered the problem of optimizing the crowd during aircraft delays before landing. Having examined the statistics, we can conclude that there was a constant increase in passenger traffic from 2013 to 2018. But also due to the constant growth of passenger traffic, the percentage of flights with delays is increasing. The problem is that that most of the flights accounted for a small percentage of the most "popular" airports (In Ukraine, 75 percent of all flights accounted for the airports of Boryspil and Zhuliany). Although since 2019 the number of air travel around the world has dropped sharply over time, the number of air travel will return to the previous number and even continue to grow. Also, a new problem has now arisen for air carriers - a significant increase in aviation fuel prices. According to the Mundi Index, since December 2021, there has been a constant increase in the price of fuel for aircraft. This is an additional incentive for airlines to optimize their routes in order to avoid unnecessary fuel costs.  In this work, on the example of a flight for a Boeing 737 from Riga to Odessa, two parameters were considered, when changing which it is possible to minimize fuel costs during a delay. An algorithm was also developed to optimize crowd costs on flights with delays.

Authors: Sineglazov Victor , Kalmykov Vadym
Published: January 2023

The paper considers the problem of constructing a training sample based on the use of semi-supervised learning a teacher. The problem statement related to the problem posed is substantiated. It is shown that obtaining a training sample in some cases is a difficult task that requires significant computational and financial costs. The use of semi-supervised learning made it possible to label unlabeled data and thus ensure the creation of a labeled sample of sufficient size. The paper gives examples of generating a training sample, as well as its use for training neural networks, which are used to solve the problem of multiclass classification. Using this approach, you can get a robust data set consisting of a small amount of manually labeled images and a huge amount of pseudo-labeled or augmented data. Using this approach, one can train a classifier to detect and classify any objects in images with bounding boxes and label them accordingly.

Damped Micromechanical Hyrovertical
Authors: Filyashkin Мykola , Smirnov Oleg
Published: January 2023

The article considers the methods for vertical gyro construction on rough microelectromechanical elements, such as: angular velocity sensors and accelerometers. It is proposed to improve the accuracy of the microelectromechanical vertical gyro by combining it with a satellite navigation system. The solutions proposed in the article make it possible to improve the accuracy of the integrated vertical gyro based on micromechanical technologies, by the means of complex data processing that uses a compensation scheme with the latest dynamic filter, which practically does not distort the errors of the strapdown inertial microelectromechanical vertical gyro, and thus obtain an estimate of the ground speed as close to the true speed as possible. Based on the obtained estimate, it is proposed to construct a scheme of the vertical gyro speed correction (damping scheme), which would significantly improve the accuracy of estimation of the angular orientation’s parameters.

Authors: Rácz Attila , Tar Melinda , Vályi Nagy Marianna , Ujj Apolka , Kristó István
Published: January 2023

Sowing and harvesting cereals with legumes is an old crop production practice. The main goal of cultivation is to make the best use of the area and to increase the quality and yield of the crops. The intercropping of cereals and legumes can stimulate the biological activity of the soil, thus increasing the recycling of soil organic matter. Competition between two or more plants has a positive effect on the nitrogen fixation of legumes. In organic form the soil enzyme activity increasing is more effective which is provided by the winter pea (Pisum sativum L.) in this crop production system. We set up our experiment at the experimental sites of the Hungarian University of Agriculture and Life Sciences, Plant Production and Agrotechnical Research Station, Szeged-Öthalom and Fülöpszállás in 2020/2021. The experiments were performed on 10 m2 plots, in four replicates, with four cereals and one winter pea species, in different phenological phases. We were used fluorescein diacetate to determine the total microbial activity of the soil. As the phenophases progress, the enzymatic activity of the soil decreases, and activity is affected by soil type. The soil enzyme activity was lower on meadow chernozem soil and higher on calcareous meadow soil. Cereal-legume intercrop systems are better able to adapt to drought. The values are higher in cereal-legume intercropping system than in cereals sowed alone. Based on our results, it can be concluded that the enzymatic activity of the soil can be increased by using soil inoculation with bacteria and mycorrhiza fungi preparations.

Published: January 2023

The main feature of our time is the "duality": we demand livable environment, on the other hand we use it in anunsustainable way to ensure the overflowing comfort of welfare societies. As a result, the use of the environment– namely the environmental elements and their systems, processes and structures – has now led to overloading(pollution, damage). So the state of our habitats, reflects our actions, there is no doubt about that. That is, ouractivity is an imprint of our thinking. Changing/modification requires innovations that facilitate the developmentand application of the embedded technologies of the future, building on the intersubjectivity of individuals.One of the cornerstones of the European Green Deal is that "economic growth should be decoupled fromresource use". Among our resources, the water – especially drinking water – is a scarce commodity. However,with prudence, care and ingenuity, we can do a lot to reduce the amount of wastewater.Our short paper demonstrates, through an example of wastewater recyclability, that increasing volumes are nolonger just a problem to solve. Rather, it is a challenge, and technological development offers a way out of itstrap, so that the society does not have to face the negative effects of declining water supply.

Published: January 2023

Continuous world population growth imposes the need to produce higher-quality food. Due to the high content of valuable protein and high concentration of carbohydrates, vitamins and minerals, soybean (Glycine max L.) is one of the most essential leguminous and oilseed crop that contributes to human alimentation and animal nutrition. This study assesses the possible impacts of soybean seedling development and seeds’ quality indicators correlate to water supply aboveground and in the root zone. The level of water management is crucial in and out of the growing season; however, the increase in temperature may adversely affect climatic conditions. As a consequence of water contained in soil, leguminous crops can improve soil texture and the capacity of minerals if admissible water is available for the crop. Soil tillage is cardinal for agricultural water management; by practising proper tillage continuously, soil properties can increase, and exposedness can decrease in the long term.

Published: January 2023

The agricultural costs can be reduced with waste water application. The effect of water quality was tested on several parameters of purslane and basil. Four treatments were applied (Irr0: non-irrigated control; Irr1: effluent water from an intensive African catfish farm; Irr2: diluted effluent water with gypsum; Irr3: Körös-oxbow lake water as irrigated control). Completely random sampling was used, ten plants were measured per treatment. For basil the benefical effects of Irr3 irrigation were detected; there were significant differences among the treatments. The highest values of the parameters were in Irr3: plant height (47.96 cm), root length (23.22 cm), biomass (164 g plant-1, fresh floral shoot tip (85.56 g plant-1), fresh stem (78.44 g plant-1) and fresh root weight (9.38 g plant-1). At basil very strong positive correlation was evinced between the biomass, and fresh root weight (p=0.01; Pearson’s r=0.87). The significantly more yield was achieved by irrigation on basil. Irrigation with undiluted effluent water (Irr1: biomass: 124.50 g/plant) is similarly effective to increase yield, as in Irr3.

Домашние животные помогают нам в повседневной жизни, оказывая психоэмоциональную поддержку. Они часто используются в трудотерапии, логопедии или физической реабилитации. Они также ценятся как компаньоны, что влияет на качество жизни человека. В этой статье обобщаются результаты социологического исследования о влиянии животных на психоэмоциональное здоровье и благополучие людей. В исследовании приняло участие 152 респондента в возрасте от 17 до 70 лет. Результаты анкетирования показывают тенденцию увеличения количества семей, имеющих домашних животных. Причѐм большинство семей предпочитает содержать в основном кошек и собак. Отмечено, что домашние животные оказывают положительное психоэмоциональное влияние на хозяев, причем на женщин в большей степени, чем на мужчин. С возрастом это влияние становится более значительным. Установлено, что люди, имеющие домашних животных, менее склонны к психоэмоциональным расстройствам. Животные также вносят большой вклад в развитие ребенка, снижая чувства одиночества и выступая в качестве друга, которому можно доверять. Домашние животные положительно влияют на психику ребенка, на снятие стресса. Причем до 5-летнего возраста эту функцию лучше выполняют кошки, а с 7 лет – собаки.

Authors: Соколова Ю.Д.
Published: January 2023

В данном исследовании представлено сравнение деградации двух основных пигментов свеклы столовой в водном растворе – бетанина и бетаксантина. Для анализа были использованы сухие, тонко нарезанные образцы корнеплода пяти различных сортов. Экспериментально показано, что, имея аналогичные альдиминовые связи, бетаксантин разрушается так же, как и бетанин: оба пигмента в воде подвергаются гидролизу. Кинетические кривые разрушения в воде идентичны. Определены константы скорости разрушения бетанина и бетаксантина. Гидролиз бетаксантина протекает с меньшей скоростью, что показано на всех образцах экспериментально. Понижение рН до 4 снижает концентрацию бетаксантина до минимума. Обнаружено, что при снижении рН во всех сортах произошло смещение максимумов поглощения бетаксантина на 30 нм в сторону коротких волн, что может быть уже продуктом распада пигмента и/или его дальнейшего превращения.

Проблема опреснения морской воды
Authors: Вещицкая Т.Т.
Published: January 2023

Вода прекрасный растворитель, и в природе нет вод, которые не содержали бы некоторого количества каких- либо веществ. Даже кристально чистый ручеек — и тот содержит в своей воде какие-нибудь растворѐнные вещества. Обычно на 1000 граммов океанской воды приходится 35 граммов растворѐнных веществ — различных солей [1]. Солѐность морской воды принято считать не в процентах, а в промиллях — т. е. в тысячных долях. Таким образом, солѐность океанской воды будет равна 35 промиллям и обозначается это так — 35‰. Состав солей воды океанов везде почти одинаков [1].

Authors: Савватеева Л.М , Кузьмин Р.М , Любская О.Г.
Published: January 2023

В статье рассматриваются проблемы экологии Арктики и Заполярного круга, а также современные способы решения этих проблем. Арктика – уникальная экологическая система, которая крайне хрупка и уязвима, но хозяйственная деятельность человека наносит ей непоправимый урон. Ко всему прочему Арктика является климатообразующим районом, поэтому даже самое небольшое изменения климата Арктики несет непоправимые последствия для всей планеты. Это значит, что решение экологических проблем Арктики должно стать приоритетной задачей государства.

Authors: Старожилов В.Т.
Published: January 2023

Работа представляет собой продолжение комплексных исследований ландшафтной школы профессора Старожилова (doi:10.24411/1728-323Х-2020-13079; doi:10.18411/lj-05- 2020-26), разработок по «Ландшафтному звену выстраивания планирования и развития экономических, градостроительных и др. структур осваиваемых территорий» (doi: 10.18411/lj-09-2020-36) и работ «Ландшафтоведение: стратегия, опыт практик в освоении территорий геосистем континент-мировой океан» (ID: 45641013). По результатам разработок, на основе проведенного синтеза, анализа и оценки ландшафтных материалов и практической реализации ландшафтного подхода в освоении территорий, формулируется и констатируется выделение нооландшафтосферы и еѐ как фокуса практик современного экологически грамотного освоения Земли. Она рассматривается ландшафтным «фундаментом» пространственной организации, обеспечивающей достижение заявленных целей пространственного развития с опорными узловыми ландшафтными структурами освоения ((DOI: 24411/1816-1863-2018-12072)), выступающих источником изменений и размещения конкурентноспособных технологий, предприятий и компаний, направленной на рациональное освоение и использование территорий, минимизацию глобальных и региональных последствий изменения природы и общества, поиск и внедрение инновационных подходов в устойчивом, экологически сбалансированном и безопасном развитии территорий. Нооландшафтосфера рассматривается основой для построения научных и практик-моделей освоения (экологических, сельскохозяйственных, карбоновых полигонов, краеведческих, экономических, социальных, градостроительных и других) и пространственного развития территорий.

Citizen Participation in the Public Decision-Making Process at the Level of the Local Public Administration
Authors: Scutariu Petronela , Mangelovschi Iulia Ramona
Published: January 2023

Through citizen participation in public decision-making, the real needs of the community are and should be included in decisions that cover those needs and are thus publicly supported. From such a direction, this micro-research aims to examine the concrete situation regarding the participation of citizens in the decision-making process by interpreting the perceptions of residents and local public administration staff in Dărmăneşti commune, to highlight the effectiveness of citizen participation in adopting an administrative decision. The approach showed that both the majority of workers in the city hall and most of the locals in the commune, who provided us with answers in the survey, appreciate that the involvement of citizens in the public decision-making process is key to democracy. Most of both respondents categories states that the main arguments for consulting the public in the process of making a public decision are: the right of citizens, ensuring the effective adoption and implementation of decisions, the decisions taken are accepted/supported by society, promoting the transparency of the decision-making process. Expressing own choice, submitting requests to the local public administration, submitting written suggestions, informal discussions tend to be considered by both the surveyed staff and the responding residents as effectve and very effective ways. On the other hand, we have found that opinion polls are one of the least effective ways for citizens to participate, with most opinions, in the case of both categories of respondents, being recorded for the small and very small response varieties.
Personal Status and Conflicts of Laws
Authors: Florea Dumitriţa , Galeş Narcisa
Published: January 2023

The legal status of the foreigner has always been of particular interest, as it has been found over time that the rights that a natural or legal person may have in a foreign country have particular consequences. Part of the population of a country other than the one in which he is located or lives, the foreigner who does not have Romanian citizenship, but who is found on the territory of a state, may have the status of stateless, refugee or displaced person. The foreigner's legal condition contains all the legal norms that regulate the legal acts and deeds of foreigners, natural or legal persons. The legal norms that regulate this matter are material norms that belong to Romanian law and, as such, the legal condition of the foreigner is subject to Romanian law, as the law of the forum, respectively as the law of the place where the foreigner is found. The sufficiently rich Romanian legislation that regulates the field took into account the particular nature of social relations, aiming to be as close as possible to concrete situations. The current trend, contained mainly in the provisions of the Civil Code that "liberalizes" the possibility of applying a different rule of law than the classical one, we consider to be a step forward and is in line with the obvious progress of the science of conflict law, also resulting from its historical evolution. The foreigner's legal status is made up of the set of rights and obligations they enjoy based on state legislation and according to international conventions. This means, concretely, the set of legal rules that regulate the foreigner's ability to use, i.e. the rights and obligations he has in a state as a foreigner. We emphasize that, also in the case of the legal person, the legal condition of the foreigner can be used, this being "that collective subject of law, holder of rights and obligations, whose personal status is governed by its national law".
Analysis of the Degree of Decentralization of Vicovu de Jos
Authors: Bilouseac Irina , Spînul Silvica Nicoleta
Published: January 2023

The local authorities in a certain community have revenues from the local budget that are often much lower than what is needed. If in the first article of this magazine we analyzed the degree of financial decentralization of the Municipality of Suceava, the seat of the county, we want to study the situation at the level of a medium-level commune in Suceava County. Although the authorities know the situation in the respective locality, they know what public services its residents still need, the lack of money in the budget makes it impossible to provide certain services, the spending of money from the budget being restricted by the existence of other administrative requirements that must be met.

Due to lack of funds, local authorities will not be able to demonstrate that they can provide quality public services to citizens. The lack of administrative decentralization that is not duplicated by financial decentralization will be doomed from the start.

Thus, the main reason for choosing the topic of this article resides in the need to know the degree of financial decentralization, the financial position and the share of own revenues in the total revenues of a certain locality, to see to what extent the local authority in a commune of average level can satisfy the needs of the population.
