Authors: Radaydeh Redha M. , Al‐Qahtani Fawaz S. , Celik Abdulkadir , Alouini Mohamed‐Slim , Tayem Nizar
Published: August 2019

This study proposes adaptive downlink association schemes for controlled device‐to‐device (D2D) communication in cellular networks. The proposed schemes utilise active devices under specific conditions to improve the network performance. Specifically, active devices are classified into two disjoint groups according to their individual quality of service (QoS) requirements from their base station (BS). The BS adaptively allocates downlink physical channels to meet individual QoS of devices using a minimal number of these available channels. The unused channels at each served device (in the first class) can be then utilised by that device to serve other devices from the second class, which are not served by the BS, via controlled D2D associations. Herein, D2D pair discovery as well as the conditions for establishing successful D2D association between the classified devices are treated. Furthermore, two D2D association schemes that vary in terms of their performance and implementation complexity to meet certain objectives at the device of interest are presented. The developed analytical results address the scenarios of idealised perfect and practical imperfect D2D association. Numerical results are provided to further explain the performance variations between the proposed association schemes under perfect and imperfect operation scenarios.
Data‐based differential matched‐mode source depth estimation for a moving source

Published: August 2019

For locating a target moving in a more general track relative to the single receiver and at an ultra‐low frequency (<100 Hz) effectively, a differential matched‐mode method is proposed to estimate the depth of a moving source. It relies on the Hankel transform fast Fourier transform (FFT) to estimate the modal wavenumber difference spectrum for extracting source depth information. For the real data, the received signal as a function of the range is first processed by FFT per block to obtain the pressure field per range. Then these pressure fields are steered and beamformed according to the synthetic aperture created by the source motion to yield the modal wavenumber difference spectrum. A normalised source‐depth ambiguity function configured using these spectral peaks is applied to estimate the source depth with knowledge of the mode depth functions or nominal modal functions. Numerical simulation and experimental data all have tested this method with reasonable success especially when the source travels in a non‐radial direction relative to the single receiver.
Numerical analysis of high‐voltage RESURF AlGaN/GaN high‐electron‐mobility transistor with graded doping buffer and slant back electrode

Published: August 2019

A reduced surface field (RESURF) AlGaN/GaN high‐electron‐mobility transistor (HEMT) with graded doping buffer (GDB) and slant back electrode (SBE) is proposed. In the GDB, the p‐dopant density increases linearly both from top to bottom and right to left. The concentrated negative space charges in the lower‐left corner of GDB attract the electric field lines from the channel and barrier towards the gate under OFF‐state, which flats the electric field and enhances the breakdown voltage (Vbr). Additionally, the low p‐dopant density near the top of GDB achieves the device with low ON‐state resistance (RON). The SBE flats the electric field along the channel above it and introduces a peak electric field near its edge. Simulation results show a Vbr of 2150 V and RON of 7.05 Ωmm for the proposed device, compared with 1701 V and 7.73 Ωmm for the conventional back electrode RESURF HEMT (BE‐RESURF HEMT) with the same gate ‐drain spacing. Moreover, due to the reduced depletion of 2DEG from the GDB, the proposed device shows slight increases in fT and fmax (8.76 and 14.80 GHz), comparing with the conventional BE‐RESURF HEMT (8.24 and 13.84 GHz).

Published: August 2019

Der Versuch einer neuen Diabetesklassifikation, welche neben den klassischen Merkmalen auch den Krankheitsverlauf und das Risiko für die Entwicklung von Folgeerkrankungen miteinbezieht, ermöglicht möglicherweise eine differenzierte Einteilung der Erkrankung. Dies könnte dazu beitragen, Behandlungen zu individualisieren und Personen mit einem erhöhten Risiko für Komplikationen bereits bei Beginn der Diagnose zu identifizieren, hin zu einer stratifizierten, zielgerichteten Therapie. Inwieweit sich die Ergebnisse hinsichtlich der 5 Diabetestypen auf andere Populationen übertragen lassen, bleibt jedoch zu überprüfen.
Land deals, and how not all states react the same: Zambia and the Chinese request
Authors: Widengård Marie
Published: August 2019

The global land rush has drawn new attention to the African state. Governments have generally been accused of brokering deals that are assumed to negatively affect local people. This framing contributes to an image that all states react in the same way, ignoring that states and customary rulers still covet control over land. By drawing on a Chinese land request for 2 million hectares in Zambia, the article argues that processes of land acquisition are deeply influenced by the shifting politics and policies within the respective country, specifically since a change of government changed the dynamics of the deal.

Published: August 2019

The vehicle detection in the aerial images is widely used in many applications. Comparing with the object detection in the ground view images, vehicle detection in the aerial images remains a challenging problem due to the small size of vehicles, monotone appearance and complex background. In this paper, we propose the solution of this issue using the convolutional neural networks. We further introduce the large-scale vehicle detection dataset with ground truth annotations for all the vehicles in the scene that considers the scene complexity due to the environmental conditions. We show the performance of the trained model with other popular neural work architectures.

Authors: Vyatkin A V , Fomina L V , Shmeleva Zh N
Published: August 2019

The article is devoted to the study of the peculiarities in decision-making by the managers of the agro-industrial complex enterprises. Managing agrarian enterprises is connected with the necessity of considering multiple factors and risks. Therefore, the decision-making under uncertainty and risk is often stressful. Recently, the study of the role of the emotional intelligence and tolerance for uncertainty in decision-making has become relevant and indispensable. The authors conducted the research using four techniques in two groups – managers and students of universities studying on programs involving the future management of people. The positive correlation between emotional intelligence measured by the MSCEIT test and the subjects’ age was established. A higher ability to emotional self-control according to the EmIn questionnaire and emotional intelligence according to the MSCEIT test among managers were revealed. Iowa Gambling Test showed significant differences in the preference for the winning decks both by gender (higher for men) and in groups – the students showed a lower degree of self-control, but a greater propensity for risk. People who seek certainty and clarity perceive their loss very unambiguously and try to avoid the risk of such an outcome in the future. Thus, the ability to understand and regulate emotions is important in the choice of solutions; therefore, emotional intelligence plays an important role in decision-making.

Authors: Zagoskin Y S , Tsirkunenko A T
Published: August 2019

The principles of increasing the precision characteristics of an agricultural electric drive are presented in this article. There are achieved by analyzing the requirements for the electric drive by the operating body. The scientific work has a relationship between the parameters of the quality of rolling the blanks for agricultural facilities and the precision parameters of the electric drive in terms of overshoot parameters and absolute positioning accuracy. It is shown that this dependence is non-linear in the position electric drive and depends more on the size of the overshoot and a significantly smaller ratio from absolute accuracy. The permissible overshoot value depends on the absolute accuracy and has range from 5 to 10%. The largest value of the overshoot is achieved with absolute positioning accuracy with an error not exceeding 2%. The obtained values of the control parameters can be successfully applied in the design of the position agricultural electric drive. So, if you provide sufficient positioning accuracy with an error not exceeding 2%, which is achieved by the use of position sensors with a resolution of at least 10 000 pulses per revolution, the modeling electric drive in the position loop can be adjusted with an allowable overshoot of 10%, and therefore, increased system performance while maintaining quality control indicators.

Published: August 2019

Searching for new ecologically and economically efficient sources of chitin is of great interest in the field of biotechnology. Nowadays, the topic is growing fast, and many scientists, researchers, primarily the representatives of the Russian Chitin Society, study and search for new sources of chitin not only from large crustaceans, molluscs, and crabs, but also from insects and small crustaceans. Domesticated and liable to breeding representatives of invertebrate animals, particularly large American Black Soldier Fly (Hermetia illucens L.) can be new and promising raw material source. The Fly is a promising object of research because it contains a chitinous external skeleton. During the studies at the Biology, Ecology and Biotechnology Department of NARFU named after M. V. Lomonosov, there were determined a sufficiently high percentage chitin yield from dead flies equal to 21.3% (1281.2 g per year per 1 m3 of a cage), almost complete absence of residual protein (C = 0.98 µg/ml) and high adsorption ability (X = 156.6 mg/g) of the extracted polysaccharide. Studied qualitative characteristics enable to consider the product as environmentally and economically cost-effective sorbent with the possibility of application in many areas of biotechnology, environmental and industrial fields of production.

Published: August 2019

During the day protein mass fraction and fat mass fraction in mares’ milk changes in different ways. The variability of fat content in mare’s milk reaches 60% within 24 hours. Several experiments, including the milking of mares continuously during the day, were conducted to explain the nature of this phenomenon. Differences in the variability of fat and protein contents in the mares’ milk during the day and various way of secretion of the milk components from udder’s secretory cells were explained by the authors in this scientific article. The protein is secreted due to merocrine secretion, and fat secretion mainly occurs due to apocrine secretion. Reduction of fat content in the mares’ milk is caused by the significant increase of milk yield in the early morning, when secretion of synthesized fat slows down. When milk yield is reduced, the secretion of stored fat is increased, which also increases the fat content in milk. It was found that in the morning milk yield of mares is higher than at night by 16.39 %. It was also found that during the day protein mass fraction is higher than it is at night by 5.24 %. The fat content in the mares’ milk during the day is higher than it is at night by 12.24 %. The ratio of daily milk yield and fat content was amounted to 0.22, of daily milk yield and protein mass fraction was + 0.44, and of fat mass fraction and protein mass fraction was + 0.47.

Pesticides as endocrine disruptors and neurotoxicants
Authors: Gerunova L K , Bardina E G , Gerunov T V , Sechkina I V
Published: August 2019

The role of pesticides in the development of endocrine disorders and neurodegenerative diseases of humans and animals is currently being actively discussed. Epidemic and model studies confirm the link between the use of pesticides in agriculture and the occurrence of adverse changes in the nervous and endocrine systems of people and animals. But the mechanisms underlying pathological changes have not yet been identified. Among the leading links in the pathogenesis of neurotoxicity, oxidative stress, neuroinflammation and epigenetic modification can be distinguished. The cause of endocrine disorders may be low-dose hormone-like effects of pesticides, leading to changes in the synthesis and metabolism of the body’s own hormones. Due to the difficulty of establishing cause-effect relationships, as well as the presence of significant gaps in the study of the pathogenesis of chronic pesticide intoxications, further studies of the biological effects of low doses of pesticides are necessary in order to establish patterns of their influence on the population health of people and animals.

Simulation of the deflection of the ice cover
Authors: Mikishanina E A
Published: August 2019

The paper proposes a mathematical model describing behavior of ice cover under loading. Not taking into account the chemical characteristics, and considering it a solid continuous medium on an elastic base, the role of which is played by water, to simulate the deflection of the ice cover under loading, it is possible to use the theory of thin shells and plates. Thus, the proposed mathematical model is based on the partial differential equation of the bending of a thin plate on an elastic base. Boundary conditions are set depending on the method of fixing the edges. Delivered the boundary value problem is solved in the class of almost-periodic functions by means of a generalized discrete Fourier transform, which allows us to move from the partial differential equation to the ordinary differential equation. The graph of the function of deflection of the ice plate is constructed.

Authors: Kovalevskiy V V , Yastrebova E A
Published: August 2019

Influence of maintenance conditions of cows of different genealogical lines on milk productivity and physiological parameters of animals is studied. Different maintenance conditions of cows in the hulls affected the level of milk yield of animals of all lines: with yard housing there is a difference in the index of milk yield for 305 days of lactation from 59.4 to 252.3 kg compared to the indexes for tie-up housing. Minimum difference in the index was observed in first-calf cows of the Reflection Sovering line (59.4 kg), which indicates the better adaptability of animals of this line to less favorable housing conditions. The relationship between high-altitude measurements and measurements determining the milk type of animals (between the height at the withers and the chest width - a positive average interrelation (0.3), and between the height at the withers and the chest girth - a positive weak (0.11)) was revealed during the study. Also, a weak positive relationship between some measurements of cows and their milk productivity (between milk yield of cows and chest depth (0.11), chest width (0.13), chest girth (0.15) was found. Comparison of the physiological parameters of cows of different genealogical lines in different housing conditions showed that significant differences were found only in terms of “respiration rate” and “pulse frequency”: when the tie-up housing, the aforecited indicators for cows of the Reflection Sovering line are significantly higher than those for herdmates. This suggests more intensive physiological processes that ensure better development and a higher level of milk productivity. Tendency to increase the number of erythrocytes and hemoglobin level in the blood of cows of the Reflection Sovering line, found during the study of influence of housing conditions of cows on the morphological and biochemical composition of blood, is preserved both in tie-up and yard housing.

Published: August 2019

Solid Oxide Fuel Cell (SOFC) is one of the promising developments in the fuel cell system. SOFC can be applied to micro-scale combined heat and power generation (micro CHP) as a power plant in housing. Recently, intermediate-temperature SOFC (500-700°C) is being widely developed since cheaper than the conventional SOFC (∼1000°C). Intermediate-temperature and conventional SOFC are less developed in Indonesia due to expensive electrode and electrolyte materials, such as Yttria and Lanthanum, which are not available in Indonesia. This study aims to develop a novel disk-shaped single cell SOFC based on materials from Indonesia’s resources. Calcia Cobalt Zinc Oxide (CCZO) is an alternative cathode to replace conventional cathode such as Lanthanum Strontium Manganite (LSM). CCZO cathode was made using spray coating. Calcia can also substitute Ytrria as a stabilizer of zirconia in electrolyte fabrication. Calcia-stabilized Zirconia (CSZ) electrolyte was produced using spray coating. NiO anode was fabricated through hydraulic pressing. The single cell was operated using hydrogen (125 sccm) as a fuel and ambient air (500 sccm) as an oxidant. The results showed an open-circuit voltage (OCV) of 0.577, 0.558, and 0.513 V and produced the maximum power densities of 1.4, 2.8, and 10 mW m−2 at 500, 600, and 700°C, respectively. Measurement of the cell impedance indicated that the overall resistance decreased with increasing temperature.

Trains are the most popular means of transportation by some people because it is cheap, fast, safe and comfortable. Because of carrying a sense of security, the construction of supporting infrastructure must be made safe, ranging from signs to the implementation of the door guard system in the railway crossing. Still often found in some railway crossing areas there is no guard door crossing system, so there are many accidents that resulted in the absence of a railway door guard system. The prototype was built to develop a railway control system by applying microcontroller technology, minicomputer and Hall effect sensor. The system will automatically detect the train that will pass by sending railway traffic safety information via the internet near the railway crossing. So that road users can find out early if there is a train that will pass by seeing the information monitor.

The existing condition of the irrigation area after construction or the irrigation area in operation needs to be evaluated because in the planning of water availability and irrigation water needs many parameters-parameters which is the result of the analysis approach or indeed the data - the data that then changed. The changing conditions of the data will cause many impacts. The risk of field failure is one of impact if water availability is less than the initial estimate. This paper reports the analysis of the availability of water and irrigation water requirements is dynamic, in this study the availability of water is analyzed with 80% reliability. Irrigation water demand is based on regulation of planting schedule and reduction of field area with the intention of reducing the risk of greater field failure. The results obtained are alternative field area of optimum irrigation, regulation of planting schedule and operation of floodgates in the taking or building structure for the review. Field area and Regulation of planting schedule are analyzed by simulation. The mathematical model that will be produced is the optimum model of irrigation water management and mathematical model of field failure risk. This study can be an evaluation model especially for irrigated areas in dry field areas.

The purpose of this paper is to present a visualization of two-dimensional trees using fractals and L-Systems. Grammar in L-System consisting of letters, axioms, and production rules can be used to construct trees in various forms according to the production rules used. With the formation of grammar from the tree pattern in a fractional manner, the grammar can be reused to construct other tree patterns at a higher level. The iterations made on certain production rules visually affect the tree model. Experiments were carried out on the L-System generator to see the results of tree visualization by testing various grammars. Testing was done by trial and error in production rules to get a realistic visualization of a two-dimensional tree model. From the experimental results produced a variety of grammar, where modifications to the production rules produced different tree models. Visually, from the iteration results, the higher the iteration value, the two-dimensional tree was not formed properly. When the iteration value or n > 5 the two-dimensional tree model results from an iteration it lost detail from the branch.

In this investigation, manganese has been produced from medium grade manganese ore from Karangnunggal mine (West Java, Indonesia). The effects of keeping it at a temperature of 1200°C in methane gas on the structural properties have been studied. The material’s properties have been characterized on the basis of the experimental data obtained using X-ray fluorescence (XRF), X-ray diffraction (XRD), Scanning Electron Microscopy (SEM), and Fourier Transform Infrared (FTIR) spectroscopy. It has been found that MnO2 is reduced to hausmannite (Mn3O4), manganosite (MnO) and manganese carbide (Mn7C3). An increase of the keeping time up to 45 minutes during the sintering process leads to an increase of the MnO concentration, while at 90 minutes, the concentration decreases. The analysis based on the interpretation of both XRD patterns and FTIR spectrum allows one to explain the blockage in the particle surface of the ore by an increase of the carbon deposition.

Published: August 2019

Silver/palladium composite nanoparticles (NPs) obtained by pulsed laser ablation in liquid (PLAL) technique catalyze oxidation of propylene glycol (PG) to lactic acid (LA) in alkaline media. The PLAL technique allows obtaining silver/palladium NPs with different silver/palladium molar ratio. Addition of palladium increases PG conversion (up to 52%) and LA selectivity (up to 88%). The reaction temperature and silver/palladium molar ratio strongly affects the catalytic activity of the silver/palladium composite NPs.

Published: August 2019

The paper deals with the study of the effect of peat mechanoactivation on the structure and biostimulating and detoxifying properties of isolated humic acids (HA) in of oil-contaminated soil. It is shown that the mechanical activation of peat leads to an increase in the HA yield by a factor of 2-3. In this case, the changes in the fragment composition of HA are observed. Hence, the percentage of aromatic and oxidized alkyl fragments increases, while the amount of oxygen-containing functional groups decreases. The binding of petroleum organic compounds occurs due to the presence of an aromatic skeleton in the structure of HA. The increase in the proportion of aromatic fragments in the structure of mechanically activated HAs increases their affinity for hydrophobic oil compounds, thereby providing them a detoxifying ability. The maximum detoxifying ability of mechanically activated HA determines their biostimulating properties in the wheat seed germination experiment. The biostimulating effect from the use of mechanically activated HA samples is manifested itself to a greater degree in the increase in the height of the sprout stem and the dry mass of the aerial part of the plant. The processes of biodegradation of oil in the soil in the presence of HA are investigated. It is shown that the amount of bitumoids extracted from the soil in the presence of HA is reduced by 30%. The content of hydrocarbons in bitumoids decreases by 50% due to the biodegradation of low molecular weight alkanes. At the same time, the degree of branching of hydrocarbon chains increases, which suggests a microbiological activity. An increase in alcohol-benzene resins in the composition of bitumoids indicates the stimulation of hydrocarbon-oxidizing bacteria by humic acids. According to the data of IR spectroscopy, the content of paraffin hydrocarbons has decreased during the destruction of oil by soil microflora.
