LONGITUDINAL NON-STATIONARY MOTIONS OF MAGLEV TRAIN
Authors: V. O. Polyakov  , N. M. Khachapuridze
Published: July 2019

Purpose. The quality of passenger’s and good’s transportation by a magnetically levitated train (MLT) is a key criterion for evaluating its consumer properties. The dynamics of a train’s electromechanical subsystem (EMS) has a decisive influence on this quality. Non-stationary modes of this subsystem’s motion, such as a speed increase, service and emergency braking, as well as the passage of the tunnel are especially critical. Therefore, the train’s motion in such modes is limited by acceptable safety standards. Based on this, the purpose of this study is to assess the dynamic qualities and load of the train in the above-mentioned non-stationary modes. Methodology. At the present stage, the main and most universal tool for analyzing and synthesizing processes in systems is their mathematical and, in particular, computer modelling. On this basis, the work was done by conducting a series of experiments with computer model of EMS MLT dynamics. This computer model was obtained as a result of the relevant transformation of the corresponding mathematical model into it. The mentioned computer model was programmatically recorded in the input language of the Mathematica computer mathematics system. Findings. The obtained results of modelling are presented in graphical form and reflect the train's motion in the modes of acceleration, the passage through a tunnel, as well as service and emergency braking. The control by the train's electromechanical subsystem in all considered transient modes of motion, with the exception of emergency braking, is carried out by changing the voltage feeding of the linear synchronous motor’s armature’s winding according to one or another law. Therefore, during modelling the train’s motion in each of these modes, frequency, amplitude-frequency, and phase-frequency control options for the motor’s armature’s voltage changing were considered. Analysis of the simulation results made it possible to estimate the MLT’s dynamic qualities in various non-stationary modes of motion and its load in their process. Originality. The research suggests setting the priority of the holistic consideration of non-stationary modes of MLT's EMS's motion. Practical value. The main manifestation of the practical value of the work is the possibility, in the case of using its results, of significant increasing in the efficiency of dynamic studies of MLT while reducing their resource intensity.

Purpose. The article is aimed to study a parametric frequency generator on noncollinear magnetic fields, which performs the functions of a stabilized power source and means of protection against the effects of powerful impulse noises in the form of switching overvoltages and lightning discharges. Methodology. To carry out experimental studies, a prototype model of a parametric generator was fabricated. A number of studies were carried out to determine the optimal parameters of the pump circuits and the circuit of the device, in which the best energy characteristics and maximum output power are achieved with stable generation in the system. Findings. The authors proved the importance to develop a means of protecting signaling equipment, centralization and blocking from the effects of powerful impulse noises. The developed construction of the device completely eliminates the transformation of energy, it means the penetration of noise from the input to the output. As a result of the experimental studies, the optimal parameters of the generator circuits, which provide its best energy characteristics, were determined. Originality. The device of the parametric generator, which has energy-consuming elements in its design, has been improved, this significantly improves the energy characteristics and properties. In order to improve the reliability of automatic blocking systems, the methods for protecting railway automation equipment and telemechanics from the effects of high-power impulse noises and high levels of traction currents were further developed. Practical value. Based on the obtained results, the device under investigation can be introduced into production and used in railway automation systems to organize a stabilized secondary power source for railway automation track equipment, as well as to protect equipment from the effects of powerful impulse noises created by lightning discharges and lightning or switching overvoltages. The results of work can also be used in re-equipment of the hauls with new railway automation systems and in the preparation of design documentation for track circuits, station systems and automatic blocking systems.

Published: July 2019

Purpose. The main purpose of the article is to analyze the presence of plastic in the water of Ukraine and the world, as well as to suggest the methods for purifying water from plastic on the basis of the world and personal experience. Methodology. The studies were carried out on the basis of the analysis of scholarly domestic and foreign literature sources on the presence of plastic in the water of Ukraine, European countries, and the USA (1999–2018). Findings. The analyzed sources indicate that one of the main environmental threats of global scale is the presence of plastic in drinking and waste waters. The wastewater treatment facilities of the world are not sufficiently adapted to detect and trap plastic. The authors present the results of a comprehensive consideration of the issues related to the determination of the presence of plastic in various waters, their size and concentrations, and manufacturing materials. Plastic, entering the body of people, especially children, animals, sea fish, etc., has a negative influence on their health. Studies have been conducted to determine the content of plastic in drinking tap water in the cities of Dnipro and Zaporozhye. For example, drinking water from the tap contains from 4 to 10 particles of plastic per liter of water, the size of which exceeded 100 microns, that is, the average thickness of a human hair. And in bottled water of well-known trademarks «Morshinska» and «Buvette» contains from 49 to 102 particles of plastic per liter of water. Originality. The paper summarizes the existing and presents new methods and technologies for cleaning water from plastic, such as: filtering on various facilities (mechanical methods), flotation, membranous and reverse-osmotic systems, membrane bioreactors (physical-chemical and combined methods). As a second way to reduce the amount of plastic in water, it is proposed to create biodegradable plastics or prohibit their manufacture. Practical value. Given the prevalence of bottled water consumption worldwide, the results of this study confirm the need for further research on the effects of micro and nanoplastics on human health.
Influence of installation method on static lateral response of displacement piles in sand
Authors: Anusic I. , Lehane B. M. , Eiksund G. R. , Liingaard M. A.
Published: July 2019

The influence of the installation method on the static lateral response of displacement piles is presented using the results from reduced-scale field tests on piles in medium dense siliceous sand. In contrast to the importance of the installation method on shaft friction, it is shown that lateral response of piles to static lateral loading is largely insensitive to the installation method. The tests show that the lateral responses of impact-driven piles with different installation frequencies and jacked piles are very similar, while vibro-installed piles exhibit a somewhat stiffer response, reflecting effects of compaction. A comparison of load test results with the predictions obtained from two design methods reveals the suitability of a method that correlates the lateral soil response to the cone penetration test end resistance.
Multi-scale modelling of kaolinite triaxial behaviour
Authors: Aminpour P. , Sjoblom K. J.
Published: July 2019

To understand the relationship between microscopic variables and macroscopic engineering properties of kaolinite particles, a molecular dynamics simulation of triaxial shear tests was developed. The calculations were based on a coarse-grained representation of kaolinite particles, considering the action of Derjaguin–Landau–Vervey–Overbeek forces and the granular interactions. The objective of this study was to provide an understanding of the micro- to macro-linkage of mechanical properties through the development of a versatile numerical framework to accurately duplicate the interactions between clay particles and to study the three-dimensional mechanical behaviour of granular matters. To understand the capabilities of the method, several computer simulations of the periodic true triaxial compression and extension tests of both isotropically and one-dimensionally consolidated specimens were carried out.
A novel formula for the prediction of swelling pressure of compacted expansive soils
Authors: Elsaidy H. , Yan W. M. , Pender M. J.
Published: July 2019

Expansive soils have been well recognised as problematic that can pose threats to the stability of the Earth's structures due to the soils’ significant volumetric change when subject to moisture variation. In this study, a modified oedometer set-up was used to investigate the one-dimensional swelling pressure of compacted soils when subject to wetting under the constant volume constraint. Four expansive residual soils found in Auckland, New Zealand were tested. Based on the findings of two soils, a prediction formula of the swelling pressure was proposed. The formula considers not only the initial condition of the soil but also implicitly the amount of swelling minerals through the material's free swell index. The formula was validated using swelling data obtained from the other two expansive soils tested in this study and from data reported in the literature. The predicted swelling pressure was found to be reasonably close to the measured pressure, considering the range of soil expansivity in this study.
Effects of micro-features of fossil diatom on the macroscopic behaviour of soils
Authors: Caicedo B. , Zuluaga D. , Slebi C.
Published: July 2019

Diatomaceous soils frequently occur in lacustrine and marine deposits. They are usually thought of as one type of material with unusual geotechnical properties characterised by high Atterberg limits, natural water content, compressibility as well as high shear strength. The combination of high liquid limits and high friction angles appears to be a contradiction in the framework of classical soil mechanics, but studies showing relations between their unusual geotechnical properties and micromechanical features of fossil diatoms may provide the key to solving this puzzle. This study considers two diatom species, Aulacoseira granulata and Coscinodiscus centralis. The study identifies the effects of their microscopic features on the macroscopic behaviour of soils. The study involves first, tests of Atterberg limits, and then oedometric and triaxial tests on samples with different proportions of the two species. Results show that the microscopic shapes of the diatoms have observable effects on the macroscopic responses of soils.
Critical issues in the determination of the bentonite cation exchange capacity
Authors: Dominijanni A. , Fratalocchi E. , Guarena N. , Manassero M. , Mazzieri F.
Published: July 2019

The swelling pressure and transport properties of bentonites are controlled by the electric charge density of solid particles, which is commonly estimated from the laboratory measurement of the cation exchange capacity (CEC). However, the standard ammonium displacement method for CEC determination does not take into account the fabric changes that occur in bentonites under exposure to high salt concentration solutions. A series of laboratory tests was conducted to assess the relevance of such a critical issue, by varying the concentration of the extracted potassium chloride (KCl) solution with respect to that of the standard test. The obtained results show that the release of the adsorbed ammonium cations depends on the bentonite fabric, which is controlled by the potassium chloride concentration. As a consequence, the ammonium displacement method may provide an unrepresentative estimate of the CEC of bentonites. The methylene blue titration method, despite its apparently more limited accuracy, instead, seems to provide a more reliable estimation of the CEC, as the bentonite fabric is maintained dispersed during the test.
Effect of Mg shell on MgH2 dehydrogenation by morphological and mathematical analysis
Authors: Shriniwasan Sweta , Tatiparti Sankara Sarma V
Published: July 2019

Magnesium (Mg) formation during dehydrogenation of nanocrystalline magnesium hydride (MgH2), exhibiting a bimodal particle size distribution (4 ± 1 and 16 ± 8 μm) at 320 and 350°C, was investigated using X-ray diffraction patterns, cross-sectional scanning electron microscopy (SEM) and transmission electron microscopy. Magnesium hydride dehydrogenation consists of an initial period of slow hydrogen gas (H2) release (incubation period). Following incubation, hydrogen release increases significantly. SEM images of the dehydrogenating magnesium hydride particles are graphically divided into several concentric annuli. The radially outward flux of hydrogen released within the particles was estimated by developing a quantitative approach. During incubation, the absence of a magnesium shell necessitates slower hydrogen atom diffusion through magnesium hydride as depicted by the flux estimation. Beyond incubation, the enhanced hydrogen release is due to the presence of a magnesium shell. Thus, the effect of the absence/presence of a magnesium shell on magnesium hydride dehydrogenation was studied using the estimated fluxes.
Bearing capacity under increasing undrained shear strength
Authors: Arnold André , Krähenbühl Manuel , Zhang Weiyuan , Askarinejad Amin
Published: July 2019

The undrained shear strength of naturally deposited, consolidated and saturated clay usually increases with depth due to the overburden pressure and the decreasing water content. Nonetheless, calculations of the bearing capacities of foundations under undrained conditions are usually done using the approach of Prandtl, which assumes constant values of the undrained shear strength. Analytical models using the kinematic element method show that the failure mechanism and the bearing capacity are both influenced by the increasing undrained shear strength; therefore, Prandtl's method might overestimate the bearing capacity of a shallow foundation assuming an average value of the undrained shear strength. Centrifuge tests of shallow strip footings on kaolin clay were conducted to validate the analytical model in terms of bearing capacity and failure mechanism. The estimated bearing capacity of the shallow foundation based on analytical models show good agreement with the centrifuge test results. However, the shape of the failure mechanisms is considerably different. In the analytical models, the development of the failure mechanism is estimated based on the assumption of a perfectly plastic behaviour, developing a rigid-body collapse. This behaviour was not observed in the physical models due to the development of the failure mechanism.

Published: July 2019

New highly productive guineagrass (Megathyrsus maximus syn. Panicum maximum) cultivars have been released in Brazil and grazing trials are necessary to evaluate their carrying capacity and forage quality. The objective of this study was to evaluate the liveweight gains of young Nellore bulls grazing 3 guineagrass cultivars under rotational stocking. The experiment was carried out in Planaltina (Federal District, Brazil) during a single rainy (November‒April) and dry (May‒August) season. Treatments were Massai (control), BRS Tamani and BRS Zuri cultivars. Zuri and Tamani pastures provided greater average daily liveweight gains (ADG) (0.38 and 0.42 kg/head, respectively) over the experimental period than Massai (0.28 kg/head). For all cultivars liveweight gains decreased markedly from May onwards at the beginning of the dry season. Nevertheless, bulls grazing Tamani and Zuri pastures still gained 0.20 kg/hd/d until late August, while those on Massai pastures gained only 0.08 kg/hd/d. The differences in ADGs can be explained to some extent by differences in quality of available forage. In vitro dry matter digestibility of plucked samples of Massai was 555 g/kg, compared with 621 g/kg for Tamani and 590 g/kg for Zuri. Crude protein concentration in plucked samples was also greater for Tamani and Zuri (71.9 and 74.2 g/kg, respectively) than for Massai (62.2 g/kg). As feed wastage was particularly high in Massai, further studies are needed to verify if higher stocking rates during the wet season could result in greater production of live weight per ha on this cultivar, assuming that ADG does not decrease further with the increased stocking rate.
Multitask VI v1
Authors: de Ruiter Julian , Aben Nanne
Published: July 2019

The Multitask Variable Importance (Multitask VI) is a modified version of the permuted variable importance score for Random Forests. Essentially, for a Random Forest trained simultaneously for multiple response vectors, it allows the inference of variable importance scores per variable and per task. For more information, see our manuscript (Aben et al, submitted,https://doi.org/10.1101/243568), where we applied this score to a dataset where each tasks corresponds to a drug combination (and hence the Multitask VI is called the Drug combination specific Variable Importance, or DVI, there).

One of the goals of mathematics learning based on Kurikulum Tingkat Satuan Pendidikan is to understand, explain and apply mathematical concepts in the context of problem solving. But in the field, the students tend to difficulties in resolving problems related to problem solving in mathematics. This is due to the low ability students in mathematical problem solving in students' learning because not used to thinking creatively. It required a real effort to improve students' problem-solving abilities in mathematics. One of the measures taken namely through mathematics model Multy Discourse Representation (DMR).

Hal ini disebabkan rendahnya kemampuan siswa dalam pemecahan masalah matematis karena dalam pembelajaran siswa tidak terbiasa berpikir secara kreatif. Untuk itu diperlukan upaya nyata dalam meningkatkan kemampuan pemecahan masalah siswa dalam pembelajaran matematika. Salah satu upaya yang diambil yakni melalui pembelajaran matematika dengan model Diskursus Multy Representation (DMR). Pembelajaran dengan model DMR merupakan salah satu alternatif yang dapat digunakan karena menghadapkan siswa kepada bekerja secara berkelompok, supaya dapat mengeluarkan daya representasi yang dimiliki oleh diri siswa.Kata kunci: Kemampuan pemecahan masalah, Model DMR, Pembelajaran matematika

Dispositional Styles in Original Tales of Adolescents with Cancer and Rheumatic Diseases
Authors: Odintsova M. , Radchikova N.P. , Sarkisyan A.O. , Kulyatskaya M.G.
Published: July 2019

The article presents the results of a study of dispositional styles, which are reflected in the content of the original fairy tales of adolescents with oncological (n=40) and rheumatic (n=50) diseases. All adolescents underwent long-term treatment in Moscow medical organizations and were students of the State educational institution of the city of Moscow School “Teaching Technologies”. A dispositional behavior style (including resilient / victimized styles) is considered as a set of attitudes formed as a result of interaction with the environment and encouraging certain behavioral reactions and actions, which reflect the “behavior signature”. It was found that in conditions of oncological and rheumatic disabling diseases that create a deficit social situation of development, adolescents are characterized by different dispositional behavior styles, each of which has a resource for compensation. For adolescents with a resilient dispositional style, compensatory resources include attitudes toward involvement, control, and risk taking. For teenagers with a victimized dispositional style, a fairy tale becomes a compensatory resource: in fairy-tales they express their feelings and reflect on the problem of finding meaning. For adolescents with an unstable style compensatory resources are a combination of resilient attitudes and fairy tale resources.
