Authors: Reidemeister O. H. , Kalashnyk V. O. , Shykunov O. A.
Published: December 2017

Purpose. The scientific work is intended to develop a methodology for describing the structure of the railway vehicles (they are considered as a system of rigid bodies connected by rigid, elastic and dissipative elements), which would allow us to obtain the equations of motion in an easily algorithmized way. Methodology. When constructing the model, authors tend to ensure that its structure reflects the structure of the mechanical system, that is, parts of the model must correspond to parts of the car. In this case, the model takes the form of a hierarchically organized graph whose vertices correspond to the bodies, attachment points of the connecting elements and to the connecting elements themselves, and the edges describe the sets of processes that are related to the incident vertexes. As a rule, these are movements and forces: for the edge between the body and the attachment point they are generalized movements of the body and the general forces acting on it; for the edge between the attachment point and the connecting element - the movements of the point and the forces arising in the element. To each vertex there corresponds a group of equations describing the motion of the system. The nature of the equations depends on the type of the vertex. For the body it is the equations of body motion; for the point - the expressions for the point displacements through generalized displacements of the body and generalized forces acting on the body, through the forces arising in the connecting element; for the connecting element - the expression for the forces arising in it through the deformation of the element. The graph can be regarded as oriented. The direction of the edge is chosen in such a way that for each vertex the values on the right-hand side of the vertex-associated equation would correspond to the incoming edge, and in the left-hand side - to the outgoing edge. Findings. A technique for constructing a dynamic model of oscillations of railway vehicles as a system of rigid bodies is developed on the basis of their description using hierarchically organized graphs. The technique was tested to construct a model of spatial oscillations of a 4-axle freight car with an axial load of 25 tons in Simulink package. Originality. For the first time, a technique has been developed for describing the structure of a railway vehicle using a hierarchical graph, which makes it possible to obtain equations of motion in an easily algorithmized manner. Practical value. The proposed methodological approach will allow, after creating a library of bodies and connecting elements, to significantly reduce the time spent on modeling the oscillations of different vehicles.

Purpose. The analysis of the existing studies showed that the increasing of energy efficiency of metro rolling stock becomes especially important and requires timely solutions. It is known that the implementation of regenerative braking systems on rolling stock will allow significantly solving this problem. It was proved that one of the key issues regarding the introduction of the above-mentioned systems is research on efficient use of electric energy of regenerative braking. The purpose of the work is to evaluate the amount of excessive electric power of regenerative braking under normal operation conditions of the rolling stock with regenerative braking systems for the analysis of the energy saving reserves. Methodology. Quantifiable values of electrical energy consumed for traction, returned to the contact line and dissipated in braking resistors (excessive energy) are determined using results of experimental studies of energy exchange processes under normal operating conditions of metro rolling stock with regenerative systems. Statistical methods of data processing were applied as well. Findings. Results of the studies analysis of metro rolling stock operation under specified conditions in Sviatoshinsko-Brovarskaia line of KP «Kyiv Metro system» stipulate the following: 1) introduction of regenerative braking systems into the rolling stock allows to return about 17.9-23.2% of electrical energy consumed for traction to the contact line; 2) there are reserves for improving of energy efficiency of rolling stock with regenerative systems at the level of 20.2–29.9 % of electrical energy consumed for traction. Originality. For the first time, it is proved that the most significant factor that influences the quantifiable values of the electrical energy regeneration is a track profile. It is suggested to use coefficients which indicate the amount and reserves of unused (excessive) electrical energy for quantitative evaluation. Studies on determination of the quantifiable values of electricity recovery for analysis of energy saving reserve showed prospects for further development. Practical value. The obtained qualified values of excessive electric energy of regenerative braking can be applicable to construction of new or upgrading of the existing metro rolling stock provided that energy efficient technical solution for the utilization, preservation and storage of such electrical energy is developed.

Purpose. Analysis and comparison of the landslide slope finite element model calculation results of the appliance of soil-cement piles, depending on the variation of the retaining structure rigidity, makes it possible to evaluate the effectiveness of their application and the cooperative work of piles with the displacement body. It also makes it possible to make a conclusion about the advantages of using this anti-landslide protection method of the slope. Methodology. Analysis of geomorphological data obtained from the results of laboratory studies of soils on the slope section is considered. Creation of a three-dimensional finite-element slope model according to the constructed sections and depths of the soil layers. Calculation of the nonlinear problem of finite element modeling of the slope with applying of soil-cement piles of various rigidity. Findings. The obtained results of calculating the finite element model of the landslide slope, and the analysis of the stress-strain state of the construction with soil-cement piles has been carried out. Originality. Despite the widespread of using soil-cement piles as enclosing structures for the construction of foundation pits and reinforcement of foundations of emergency structures, special attention should be paid to the study of the expediency of using soil-cement retaining pile structures on landslide areas. Practical value. It is known that soil-cement retaining piles are expediently in use as a protective element, which interacts quite well with the ground environment due to its structure of the initial material. Using of modern computer programs of finite element modeling makes it possible to calculate the efficiency of the use of soil-cement piles and to determine the parameters of the necessary retaining structure according to the given geological structure of the slope, and also, depending on its shape and the physical characteristics of the soils, to compare the performance of different protective landslide structures types.

Published: December 2017

Purpose. On the basis of the results analysis of the computer simulation and laboratory studies it is necessary to determine the changes impact dependence of the hydraulic level of groundwater on the tunnels processing stability in the underground due to the deformations development of the surrounding dredging massif. Methodology. The methodological basis of the research complex consists of the analysis, generalization of known scientific results and practical experience of forecasting and preconditioning of deformations of tunnel and surrounding soil mass processing, as well as computer simulation of the critical stress-strain state of the tunnel processing at changes in the hydraulic level of groundwater. Findings. In the process of technological construction and under the non-pressure groundwaters impact, when operating tunnels of subway lines of shallow foundation, the stability of all-section machining is ensured due to the uniform hydrostatic reduction of processing. At this the sediments are within the permissible values. The results of the research show that different levels of hydrostatic pressure can occur when the groundwater level changes from both sides of the tunnel. At the same time, there is a redistribution of stresses of the soil mass around the cross section of the tunnel, which, in turn, leads to the appearance of additional non-uniform deformations and the opening of cracks in the tunnels during operation. Originality. The authors of the work firstly established the effect of changes in hydrostatic pressure, which may arise due to fluctuations in the level of groundwater on the whole-section processing of tunnels of metro lines of shallow foundation due to secondary sedimentation. The conditions of occurrence of the secondary sediment have been determined and the nature of the deformation course has been established during the operation of the shallow subway. Practical value. At the stage of designing the metro lines of the shallow foundation, it is necessary to take into account the possibility of uneven precipitation from the action of hydrostatic pressure during operation. This will avoid additional deformations during the seasonal period, reduce the number of current repairs, increase reliability and the useful life of the tunnel processing structures.

The qualitative and quantitative characteristics of entity were performed and the regularities of elements interaction in the system of road goods transportation were found out. The role of the road in transport industry and the influence of transportation and logistics space on the road itself in the process of its functioning were clarified. In the study of this topic the system approach, methods of synthesis and rational problem solving, theory of mass service were used. Findings. The work presents the highway as an element of the cargo transportation system that will make it possible to increase its economic efficiency in a constantly changing environment of transportation and logistics space according to the chosen criterion, the lower total costs to promote material flow. Theoretical-methodological bases of perfection of logistics system of cargo delivery by road transport include substantiation for the use of logistics as an effective control element to reduce the costs associated with goods transportation.

Authors: Samosvat V. O. , Rongling Zhang , Hololobova O. O. , Buriak S. Y.
Published: December 2017

Purpose. Investigation and analysis of the hanger arrangement and the structural stability of a Network arch bridge – a tied-arch bridge with inclined hangers that cross each other at least twice. It is also necessary to make a comparative analysis with other types of hanger arrangements. Methodology. The authors in their research investigated a large number of parameters to determine their influence in the force distribution in the arch. Eventually they determined optimal values for all parameters. These optimal values allowed developing a design guide that leads to optimal arch design. When solving this problem, the authors used three-dimensional finite element models and the objective was to determine the most suitable solution for a road bridge, with a span of 100 meters, consisting of two inclined steel arches, located on a road with two traffic lanes, subjected to medium traffic. The virtual prototype of the model is performed by finite element simulator Midas Civil. Findings. In this study, for the bridge deck, a concrete tie appears to be the best solution considering the structural behavior of network arches, but economic advantages caused by easier erection may lead to steel or a composite bridge deck as better alternatives. Design requirements and local conditions of each particular bridge project will decide the most economic deck design.Originality. To ensure passenger comfort and the stability and continuity of the track, deformations of bridges are constricted. A network arch is a stiff structure with small deflections and therefore suitable to comply with such demands even for high speed railway traffic. A network arch bridge with a concrete tie usually saves more than half the steel required for tied arches with vertical hangers and concrete ties. Practical value. Following the study design advice given in this article leads to savings of about 60 % of structural steel compared with conventional tied arch bridges with vertical hangers.

Purpose. The implementation of the magnetically levitated train’s (MLT) levitation force (LF) occurs during the interaction between fields of superconducting train’s (STC) and short-circuited track’s contours (STC), which are included in to levitation module (LU). Based on this, the purpose of this study is to obtain a correct description of such interaction. Methodology. At the present stage, the main and most universal tool for the analysis and synthesis of processes and systems is their mathematical and, in particular, computer modeling. At the same time, the radical advantages of this tool make even more important the precision of choosing a specific methodology for research conducting. This is particularly relevant in relation to such large and complex systems as MLT. For this reason, the work pays special attention to the reasoned choice of the selective features of the research paradigm. Findings. The analysis results of existing versions of LF implementation’s models show that each of them, along with the advantages, also has significant drawbacks. In this regard, one of the main results of the study should be the construction of this force implementation’s mathematical model, which preserves the advantages of the mentioned versions, but free from their shortcomings. The rationality of application, for the train’s LF researching, of an integrative holistic paradigm, which assimilates the advantages of the electric circuit's and magnetic field's theory’s, is reasonably justified in work. Originality. The scientific novelty of the research – in priority of such a paradigm’s and the corresponding version’s of the LF’s implementation’s model’s creating. Practical value. The main manifestation of the practical significance of the work is the possibility, in the case of using its results, to significantly increase the effectiveness of dynamic MLT research while reducing their resource costing.

Numerical and analytical solutions of poroelastic problems
Authors: Verruijt Arnold
Published: December 2017

For a number of problems of consolidation of soils (or poroelasticity), analytical solutions and numerical solutions are presented. The numerical solutions are primarily based on the method of finite elements in space and a single finite difference in time, so that the solution is obtained in the form of a stepwise process. Because of the mathematical complications in deriving analytical solutions, it is to be expected that engineers will use mainly numerical methods of solution. For this reason, it is important to consider the accuracy of these methods by comparing them with analytical solutions. For the problems considered in this paper, it appears that the numerical results are very close to the analytical results.

Published: December 2017

Rapid and early diagnosis of systemic infections is very important for acting on time with an adequate therapy. The aim of this study is to determine the diagnostic importance of procalcitonin (PCT) and C-reactive protein (CRP) of bacterial infections in different stages of sepsis.PCT and CRP have been determined in 45 newborns, 1-21 days of age, with different stages of sepsis, in the centre for prematurely born neonates. These parameters have also been determined for control group, in which there were 10 healthy newborns. Procalcitonin values were significantly increased in neonates with septic shock (92,5 ng/mL; 6,06-200 ng/mL) compared to the systemic inflammatory response syndrome- SIRS (41 ng/mL; 0,28-200 ng/mL), neonatal sepsis (10,26 ng/mL; 1,08-111,3 ng/mL), neonatal sepsis and purulent meningitis (9,80 ng/mL; 4,3-18,9 ng/mL). The control group values were lower than 0,5 ng/mL. CRP is increased without statistical differences in all stages of sepsis in newborns with septic shock (93,2 mg/L; 6,0-196 mg/L) in cases with SIRS (45,64 mg/L; 6,0-147 mg/L), neonatal sepsis (70,02 mg/L; 6-177 mg/L), neonatal sepsis and purulent meningitis (61,98 mg/L; 24-192 mg/L). The average values for the control group were 4,7 mg/L. Procalcitonin is increased in all stages of sepsis with higher values in the septic shock. The increase of PCT levels is related to the severity, course of infection and prognosis of disease.

FIGHT AGAINST CORRUPTION IN UKRAINE AS THE PRECONDITION FOR INTRODUCTION OF VISA-FREE REGIME WITH THE EUROPEAN UNION
Authors: Mushak N.
Published: December 2017

Nowadays, the only unreformed component, which remains within the legal system of Ukraine is the Ukrainian court system. The main factors that affect the activity of the courts in Ukraine are both political and economic corruption. If we compare the degree of influence on the courts, we can say that the activity of the CCU mostly suffers from political corruption while the economic corruption significantly affects the activity of courts of general jurisdiction.
To implement legal instruments to combat corruption in Ukraine the appropriate system of enforcement bodies has been implemented. It involves the National Anti-Corruption Bureau of Ukraine (hereinafter – NABU), Anti-corruption Prosecutor Office, the National Agency for the Corruption Prevention (hereinafter – NACP) and the Agency for Investigation / Return Assets.
The article defines that unresolved problem is the launch by the National Agency for the Prevention of Corruption of the electronic declaration system to be held on 15 August 2016. The launch of e-declaration is an essential is the final commitment of Ukraine to obtain the free visa regime. The final decision on the implementation by Ukraine of the criteria of the Action Plan on Visa Liberalization was approved by the EU Commission on 18 December 2015. The document stipulates that Ukraine fulfilled all the criteria set of four blocks of APVL. Nowadays Ukraine is expecting to get the visa regime from the EU.
In general, for effective implementation of anti-corruption policy in Ukraine should be introduced a systematic approach. The phenomenon of corruption is systemic, and accordingly it must be overcome only by joint efforts. It is necessary to ensure the independence of anti-corruption bodies and prevent their political dependence on the governing bodies; establish effective work of the National Agency for Corruption Prevention, the National Anti-Corruption Bureau, Anti-corruption Prosecutor's Office and the Agency for Investigation/return assets must; inform the public on their performance; and to provide penalties for officials who committed corruption offenses.
REFUGEES AS A FACTOR OF ECONOMIC DEVELOPMENT IN HOST COUNTRIES OF MIGRATION
Authors: Stakanov R.
Published: December 2017

The article analyses refugee impact on economic development of host countries. About two-thirds of all international migrants reside in 20 countries. Total number of refugees in the world was estimated at 19.5 million people in 2014, the number of refugees reached the highest level since World War II. Unlike the voluntary migration, the vast majority of refugees head towards developing countries. It must be stressed that forced migration flows generate significant negative political and economic consequences for the world as a whole. Forced migrants tend to come to those regions where there are no significant employment opportunities. The assumption that receiving a large number of migrants by developed countries may cause unemployment or reduce wages or leads to a significant increase in the cost of public finances due to the rise in social payments is largely unconfirmed. Forced migration being poorly guided, as it is an intrinsic feature of today's stage, creates significant negative externalities to neighbouring regions and the world at large. There is a sizeable difference between forced and voluntary migration for their economic and political consequences. In terms of economic prospects, the difference between forced and voluntary migration should disappear over time. The paper studied the mismatch of supply and demand for certain skills on the labour market that is much more of a problem for developing countries because they receive large volumes of refugees in relation to the total population of their countries and have far fewer opportunities for leveling the imbalance in the economy by attracting additional amount of capital.

The present study was undertaken to develop yoghurt from goat milk and to assess its sensory, chemical, microbiological and storage quality. Three different cultures were tried and incubation temperatures viz. 30, 37 and 420C were selected. Yoghurt was prepared using 3% mixed culture containing Streptococcus thermophillus and Lactobacillus bulgaricus NCDC 144 in the ratio of 1:1. The product was prepared in five replicates and analysed for sensory attributes such as flavor, body and texture, colour and appearance and overall acceptability on 9-point hedonic scale by a panel of five judges. Based on overall acceptability of the product, the best incubation temperature (420C) was selected. The product prepared with optimized incubation temperature was further subjected for chemical, microbiological and storage quality. It was observed that goat milk yoghurt contains less percentage of total solids and higher titrable acidity than cow milk yoghurt. The sensory and microbiological quality of the product was evaluated on 0, 3, 6 and 9 days at refrigeration temperature (4±10C) to assess the storage stability of the product. The sensory attributes change significantly (p£0.05) after 9th day of storage in control and developed product both. The product had total plate count of 106 cfu and decreased significantly (p£0.05) after 9th day of storage (104 cfu/g). The coliform and yeast and mould count were not detected, both in control and developed product throughout storage period. It may be concluded that good quality goat milk yoghurt can be prepared by using mixed culture at 3% concentration with incubation temperature of 420C for 8 hours.

Published: December 2017

Fibre rich cookies were prepared by substituting refined wheat flour with carrot pomace powder (CPP) at 5%, 10%, 15%, 20% and 25% and evaluated for its physical properties, chemical composition, textural properties and sensory characteristics. The weight and thickness of the cookies increased whereas the diameter, spread ratio and spread factor decreased with the increase in CPP in flour blend. The moisture, crude fibre and ash content increased whereas the protein and carbohydrate content decreased with the increase in CPP in flour blend. The fat content of the cookies showed no pronounced variation. The hardness of the cookies increased with increase in the level of incorporation of CPP in the flour blends. CPP improved the appearance of cookies by imparting it attractive colour; however the texture score decreased with the increase in the level of supplementation. Cookies with 10 % CPP were found to be most acceptable due to attractive appearance; and better taste and flavour.

Published: December 2017

Thirty two weaned piglets were randomly divided into three groups allotted to the three dietary treatments, T1- control ration, T2- control ration plus 5 per cent fat and T3- T2 plus 150 mg/kg carnitine. The total dry matter intake, fortnightly body weight of each individual animal and economics were recorded. There was a significant improvement (P>0.01; and 0.05) observed for pigs under supplemented group (T2 and T3) than that of control group (T1) with regards to all growth parameters studied during growing phase than finisher phase and overall period. The cost of feed per kg weight gain during the overall period was found to be comparable among treatments (T1, T2, and T3). It may be concluded that primary response of pigs to dietary supplements were more during growing stage than finisher and inclusion of 5 % fat would be beneficial for improving growth in weaned LWY piglets.

Hot and chilling carcass weights of Suffolk and German Mutton Merino lambs were significantly different (P>0.05). The findings of the current study showed that Suffolk lambs tended to have higher hot and chilling carcass weights, although there were no statistical differences between the two genotypes in terms of slaughter weights, average daily weight gains and other slaughter traits. These results also indicate that the carcasses for retail sale from the Suffolk lambs were more in quantity when compared to German Mutton Merino lambs.

In order to broaden the genetic base of lentil, induced chemical mutagenesis was performed. Dry and healthy seeds of lentil cultivars Pant L 406 and DPL 62 were treated with 0.02% MMS (6hrs), 0.04% MMS (6hrs), 0.02% MMS (9hrs) and 0.04% MMS (9hrs) prepared in sodium phosphate buffer at 7.0 pH for 6 hours at room temperature. Bio-physiological observations showed almost a direct relationship with the MMS concentrations and treatment duration, where inhibition and sterility increases with increase in concentration and duration. The 0.02% and 0.04% for 6 hrs treatments of MMS were found effective in inducing sufficient genetic variability in both the cultivars of lentil especially for selection of yield attributing traits, and 0.04% for 9 hrs induced higher desirable phenotypic variations with few unique phenotypes of future interest, whereas 0.04% for 9 hrs found to have highest lethal dose value and % variations in the all variant small survival population. Plant habit and leaf morphology were found most sensitive phenotypic category towards the MMS doses used. Also the character association between yield and other agronomic traits were altered and improved due to the mutagenic treatments. Overall, the results were promising and useful for future crop improvement work on lentil.
Optimization of potential field parameters using genetic algorithm
Authors: Guzel Mehmet Serdal , Ajabshir Vahid Babaei , Can Serhat , Bostanci Erkan
Published: December 2017

This paper addresses a metaheuristics approach to optimize the parameters of the potential fields (PF) method. This method is an important algorithm and is primarily used for local navigation problems. However, estimating the appropriate parameters is essential for safe and smooth navigation. For instance, complex scenarios that include long and thin corridors or cluttered environments having numerous obstacles require reliable parameter estimation. Accordingly, the genetic algorithm is utilized to estimate the appropriate algorithms to overcome conventional navigation problems based on the PF method. The experimental results verify the reliability and efficiency of the proposed approach.

Keywords: Path planning, potential fields (PF) method, genetic algorithm (GA), DEAP, robot navigation, parameter optimization.
Experimental and theoretical modelling of the electric and magnetic fields behaviour in the vicinity of high-voltage power lines
Authors: Wafa Tourab , Amel Ourici , Abdessalem Babouri
Published: December 2017

This paper consists of an experimental and analytical characterisation of the electromagnetic environment in the medium surrounding a circuit of two 220-Kv power lines running in parallel. The analysis presented is divided into two main parts. The first part concerns an experimental study of the behaviour of the electric and magnetic fields generated by the selected double-circuit at ground level (0 m). While the second part simulates and calculates the field profiles generated by both the lines at different levels above the ground, from 0 m to the level close to the line conductors at 20 m above the ground, using the electrostatic and magnetostatic modules of the COMSOL multi-physics software. The implications of the results are discussed and compared with the International Commission on Non-Ionizing Radiation Protection reference levels for occupational and non-occupational exposures.

Keywords: High-voltage power lines, low-frequency electromagnetic fields, finite element method, electromagnetic compatibility, inductive and capacitive coupling, standards.
Modelling and control of wind turbine doubly fed induction generator with MATLAB simulink
Authors: Leila Merabet , Mounira Mekki , Amel Ourici , Salah Saad
Published: December 2017

This paper describes the modelling and control system of a wind turbine, using a doubly fed induction generator. This configuration makes the wind turbine suitable for variable speed wind energy application. The power captured by the wind turbine is converted into electrical power by the induction generator, and it is transmitted to the grid by the stator and the rotor windings. The control system generates voltage command signals for rotor converter and grid converter, respectively, in order to control the power of the wind turbine. Reactive power exchanged with the network through the converters is set to 0 VAr. The control strategy has been developed using MATLAB/Simulink. The simulation results are presented and discussed in the conclusions.

Keywords: Wind energy, doubly fed induction generator, grid power, modelling, control.

THE CHANGE OF RELIGIOUS UNDERSTANDING FROM IDEAL-RATIONALITY TO PRAGMATIC-MATERIALISTIC
Authors: Ishomuddin Ishomuddin
Published: December 2017

The study is conducted because of the appearance of many new beliefs in Islam, which has had considerable influence for Indonesian Muslims, regardless the fact that the beliefs have mostly been classified as a cult. The purposes of this study are to investigate the new phenomenon in the religious act, involving the change of understanding from ideals-rationality view to pragmatic-materialistic view, and to focus on the phenomenon of the emergence of new faiths in Islamic society in Indonesia. This study is aimed to answer the following questions: (1) What motives lie behind the change of religious understanding from ideals-rationality view to pragmatic-materialistic view in today's Muslim group?; (2) How does the changing process of religious understanding occur in the Muslim group?; (3) Why do religious people today tend to be pragmatic-materialistic oriented and leave the religious teachings that have been previously understood? Qualitative approach is used to examine the research questions. The research result shows that there are three kinds of typology of Muslim groups which experience a shift in religious understanding from ideality-rationality belief to pragmatic-materialistic belief. This happens because there is a gap between the quality of faith and the desire to become instantly rich.

 

Penelitian ini dilakukan untuk mendeskripsikan dan memahami gejala new act dalam beragama yaitu fenomena pergeseran pemahaman spiritual dari idealitas-rasionalitas ke pragmatis-materialistis dalam beragama. Penelitian ini difokuskan pada fenomena munculnya kelompok-kelompok atau aliran-aliran baru dalam masyarakat Islam di Indonesia. Secara rinci penelitian ini adalah untuk menjawab pertanyaan-pertanyan berikut ini. Apa yang melatarbelakangi adanya perubahan pemahaman agama dari idealitas-rasionalitas ke pragmatismaterialistis dalam beragama masyarakat sekarang ini? Bagaimana proses perubahan keberagamaan itu terjadi pada masyarakat Islam? Mengapa umat beragama sekarang ini cenderung kepada pemahaman agama secara pragmatismaterialistis sehingga kehilangan orientasi dan meninggalkan ajaran-ajaran agama yang telah dipahami sebelumnya? Penelitian ini menggunakan pendekatan kualitatif. Berdasarkan analisis data terdapat tiga macam tipologi kelompok muslim yang mengalami pergeseran pemahaman agama dari idealitas-rasionalitas ke pragmatis-materialistis. Hal ini terjadi karena adanya kesenjangan antara kualitas keimanan dengan keinginan untuk menjadi kaya secara instan.
