Published: April 2019

The Electrical power system, field engineers always strive to design a Real time power system model to anticipate the practical outcomes. The simulation software not only fixes the changes in power system, but also trying to perceive the potential impact of power system before construction. A realistic model of the power system is very essential for the future and present operations. Present, this paper makes center of attention on designing of 3-phase power system network of IEEE 57 bus power system network within the Matlab Simulink module. It supports GUI (Graphical User Interface) based models of power system components, which are used to design a dynamic model of the power system. The present design is based on the test case data and the one line diagram; so that the three-phase model is equivalent to single phase one line diagram. The simulation of this model allows for verification of voltage, current, active power and reactive power of each bus and variation of those parameters with respect to time domain waveform. The present model is also useful for learning the operation of the power system network under Steady state, Transient state and Dynamic state with the application of FACTS, Fuzzy, and ANN etc.

Published: April 2019

The electromagnetic field calculation for a floating aluminum disc is difficult to calculate since the equation involved does not produce a closed solution. The numerical, analytical, semi-analytical techniques that are already developed to find these magnetic fields have no proper mathematical formulation when the disc is disturbed from its coaxial position. The stabilization of disc is going to be effected when the disc moves away from its coaxial position due to a change in inductance between the disc and coils, due to change in magnetic flux linkage, etc. In this paper, a 2D FEM model is developed to determine the magnetic fields on a floatingaluminum disc when it is moved away from its coaxial position. The 3D FEM model developed is simulated in both COMSOL-Multiphysics and ANSYS-Electronics. The results obtained by simulation are compared, for accuracy, with the numerical solution developed earlier using Finite Difference method (FDM) and also discussed.

Published: April 2019

Creation of conditions for optimal flow of Bingham media, such as ready-mixed concrete and mortar mixes, in the circular pipeline during delivery by various types of transporting equipment has not been sufficiently studied so far. Purpose: finding patterns of flow of concrete and mortar mixes in different sections of the pipeline, based on the variability of the viscosity coefficient when the medium is flowing through long circular pipes. In calculations of the flow capacity of mortar and concrete pipelines and the required power of the pumping equipment, the properties of concrete and mortar as Bingham media should be taken into account. Dependences for description of the operation process of flow of concrete and mortar mixes through circular pipelines have been found on the basis of the Buckingham equation in the laminar flow mode.Dependences of determination of flow rate and required power with continuous delivery of concrete and mortar mixes in the pipeline, as well in case of alternate inlet pressure variation are presented. Law of variation of μр can be obtained only experimentally, which also results in errors in the computation model.

Authors: Voronin Serhii , Onopreychuk Dmytro , Stefanov Volodymyr , Bashkatov Yevhenii , Panchenko Vitalii
Published: April 2019

The structure of reduction of construction duration which takes into account the effect of the electrostatic field on the power fluid of a hydrostatic power drive of earth-moving machines is considered. Experimental studies are also considered that suggest that the exposure of the power fluid to an electrostatic field leads to the intensified formation and increased thickness and bearing capacity of the lubricant film on the friction surfaces of the hydraulic drive. This causes the reduced wear rate of the components of a hydrostatic power drive. In particular, gaps in plunger pairs in the pump are reduced, which contributes to the increase of the coefficient of performance. As a result, the operating speed of the driven equipment increases, i.e., the work cycle duration is reduced, and hence the capacity of earth-moving machines increases and the duration of the preparatory earthwork, which is about a quarter of the total duration of all construction works in general, is reduced.

Published: April 2019

The possibility of increasing the service life of 18-100 three-piece bogies by using taper bearing units with different types of adapters is considered in the article. The main task is the need to increase the longevity of the running parts of freight cars by reducing their dynamic loading. The solution of this problem is possible by improving the axle boxes. To determine possible design solutions, an analysis was made of modern domestic and foreign designs of bogies using bearing assemblies with adapters and three types of adapters with the highest quality indicators, namely the half-box of the 18-7020 bogie, adapter with elastic packing and adapter of the 18-4129 bogie. Three models of adapters were investigated using the finite-elements method, which, in accordance with reported manufacturer’s data, have high reliability index and can provide equal load distribution between bearing systems rollers. The results of mathematical simulation suggest that the forces applied to the bearing systems rollers largely depend on the adapter design. Furthermore, the studied adapter designs are not acceptable and require further designing.

Published: April 2019

The urgency of transportation organization improvement in the system of agricultural products delivery to the country’s population under conditions of import substitution is substantiated here. The article proposes to use the logistic approach. The advantage of the approach is that it combines and considers the processes of harvesting, transportation and distribution of goods in reciprocal relationship; and on this basis the concept of united harvesting, transportation and distribution complex (HTS) is introduced. The main organizational schemes for agricultural products delivery from the producer to the places of consumption are considered. Mathematical formulation of the vegetables transportation system optimization at HTS complex is performed based on the inclusion of receiving and classification units (RCU) in the logistics chains of delivery from the producer to the places of agricultural products consumption. An optimized multi-factor economic and mathematical model is proposed. It allows to identify RCU rational locations and their capacity, to calculate the number of road transport vehicles necessary to deliver vegetable cargo in full, provided that the recipients are optimally assigned to the product suppliers and available vehicles are optimally distributed for all modes of transport. Methods of the process main characteristics calculation are described.

Published: April 2019

The Ukrainian railway transport is the leading branch in the national road transport complex. Until recently, the Ukrainian railways have been satisfying the transportation needs of the economy and the population. Today, the service life of the technical resource of railways is practically expired. Therefore, there is a threat that the railway transport fails to satisfy future transportation needs of the Ukrainian economy.According to the accounting reports of Ukrzaliznytsya PJSC, at the end of 2016, the deterioration level of the fixed assets in the industry was 69.4%. In the context of a constant budget shortfall, the most urgent issue for Ukrainian railways is focusing on activation of innovation activity. We believe that most of the schemes of the traditional economy in the 21st century no longer work; therefore, alternatives should be searched for, the most obvious of which now is the cryptoeconomy with its decentralized system. The development and implementation of innovations in the Ukrainian railway industry requires new approaches to the system of financing innovations in the country; in this respect, ICO is a modern and promising method of attracting investments.

Published: April 2019

Digital Image Processing is a method to obtain image or to take out useful details or feature from image. The noise will cause the results of error in the image acquisition process. Generation of higher noise levels in the low light condition environment will often result in oversmoothed edges and textures during the denoising process because of lower signal levels in the image. Thus, this study goal is to improve denoising techniques for Poisson noise removal in low light condition for surveillance images. The Patch-Based Noise Level Estimator is designed to estimate the noise level of noisy image. The noisy image then fed to either OTSU WIE-WATH Filter or OTSU KU-WIE-WATH Filter automatically based on the noise level of image. The OTSU WIE-WATH Filter is used for low and medium Poisson noise removal while OTSU KU-WIE-WATH Filter is used mainly for high Poisson noise removal. The proposed denoising technique performances are analyzed with other existing denoising techniques in terms of Mean Absolute Error (MAE), computational time and visual effect inspection. The results verified that proposed technique is effective  in removing different level Poisson noise in low light condition surveillance images.

Published: April 2019

The method of reinforcing the soft clays with stone columns is the most commonly adopted technique to enhance its load carrying capacity and to reduce settlements. Their performance with respect to bearing capacity is well researched, but the understanding of settlement characteristics still requires extensive investigations. Moreover, no studies have been made to explore the effectiveness of stone columns using Lightweight Expanded Clay Aggregate (LECA) as filler material replacing normal stone/aggregates in order to improve settlement behavior of soft clay. LECA is known as a common lightweight material that have been applied successfully in civil engineering works where weight is an issue because the materials can help to reduce dead loads and lateral forces by more than half in installations over structures and those with soft soils. The purpose of this work is to assess the suitability of reinforcing technique by LECA columns to improve the settlement through finite element. The analysis of performance of LECA column in soft soil improvement was conducted through finite elements methods by using Plaxis 3D commercial software. Based on the results the settlement ratio was reduced as the column length increased until unity at end bearing condition where β=1.0. It is also observed that bulging was reduced with closer spacing between LECA columns.

Published: April 2019

Ungauged catchment occurs when no runoff data are available or when very few ground rain gauges are located in a huge catchment.  For these catchments, the parameters to be used in rainfall‐runoff models cannot be attained just by adjusting runoff information and thus should be procured by different techniques. Show parameters that require orientation are normally transposed from comparable measured catchments. The rainfall runoff simulation is very important to estimate and predict the flow in ungauged catchment. This investigation reviews ideas to differentiate hydrological comparability for transposing parameters from a gauged to an ungauged catchment. Model parameters that are physically based are generally derived from other information close to the ungauged catchment of intrigue. The primary challenge with rainfall‐runoff demonstrating in ungauged catchments is the absence of neighborhood ground precipitation and streamflow information to be utilized in aligning the proposed show parameters. Parameter alignment is useful since adjustment can represent the impacts of hydrological set up in a specific catchment. Since hydrological models are especially reliant on their limit conditions, the alignment practice directed can modify the predispositions of info information utilized. Parameters' adjustment can fundamentally improve the execution of rainfall‐runoff models since it included media properties of soil and vegetation which are exceptionally heterogeneous and basically are in every case inadequately known. Alternative methods for ungauged catchments are required which are the subject of this study. This study summarizes the important methods used in an ungauged catchments, discusses the issues of using satellite data as a substitute input to rainfall‐runoff models and its comparison with point scale ground data.

Authors: Ong Mei Yin , Salman Bello , SAL Nor-Insyirah , Hussein Refal , Nomanbhay Saifuddin
Published: April 2019

Currently, the biodiesel production technology is moving toward the trend of non-catalytic reaction under subcritical condition as the conventional non-catalytic transesterification requires high energy input and high production cost. Hence, non-catalytic biodiesel production under subcritical condition using microwave energy is proposed. Before that, thermogravimetric analysis (TGA) was conducted to characterize the biodiesel feedstock and determine the suitable experimental temperature range for the proposed method. Besides, the thermal behavior of the palm oil and biodiesel at different stages of reaction was also investigated. The results showed that the palm oil and biodiesel were started to degrade from 335ºC and 160ºC respectively. However, the degradation point of palm oil was higher than the supercritical temperature of DMC. So, external energy is needed to bring down the operating condition, such as microwave energy as it has potential to reduce the activation energy. To further eliminate the problem of biodiesel thermal degradation during the transesterification process, the suggested experimental temperature range is within 80ºC to 180ºC, which is from the temperature lower than the boiling point of DMC (<90ºC) to the temperature slightly higher than the biodiesel thermal degradation point. Furthermore, DSC result indicated that palm oil requires 518.35kJ/mol to decompose.

The result shows that the measurement of material attenuation will be decreased after annealing, tempering and quenching process from 40% until 99% compared to before the heat treatment process. The highest attenuation decreasing can be seen on the sample block with the 30mm thickness in the heat treatment process.Â Â

Organizations have made significant investments in ICT projects, hoping to gain competitive advantages, growth and improvement of productivity. The success and failures of the project is one of the fields in Project Management with most frequently discussed. Project planning is an important part in the project management and has a stronger impact on project success. However, weakness in project strategy and planning lead to lack of business support, inefficient use of resources, poor estimates, poor scope control and increase risks. Previous studies have reported that well-defined project plans play an important role in the success of the project. In recent times, various factors contribute to project success namely; organizational, human, project management, complexity, quality, and technical. Hence, this study aimed to explore and identify critical success factors on project planning that lead to project success. A model is derived from findings of the literature review and tested within the Malaysian public sector through quantitative methodology. Thus, the finding of this study provide the organization with insight to drive their performance improvement in managing investments for project management field, especially through strengthening employees and organization competence as well as benefit the publicâ€™s sector.

Calcium rich solid base catalyst was synthesized from local waste carbide lime and its catalytic performance was evaluated via biodiesel production. Carbide lime waste was used to produce CLW-I and CLW-II solid base catalyst using different preparation methods. Characterization including base strength analysis, scanning electron microscope (SEM), energy dispersive X-ray spectroscopy (EDX) and X-ray diffraction (XRD) were investigated. Catalytic strength was examined by deploying the solid base catalysts for transesterification reaction of palm oil. Fourier Transform Infra-red (FTIR) was used to analyze the presence of ester group in biodiesel. The yield of biodiesel conversion was calculated based on the mass of biodiesel and glycerol. The highest biodiesel conversion rate of 75.30% was achieved by CLW-I solid base catalyst at 9% loading. The good catalytic performance of carbide lime waste derived solid base catalysts proves that it has high potential to replace the usage of conventional catalyst in the biodiesel industry.

On the basis of institutional governance perspectives, it examines internal and state factors influencing the carbon emission disclosures among 75 electricity companies in Asia. It content analysed the annual reports and stand-alone sustainability reports for the year 2013. Overall, the findings suggested that the adoption of GRI Sustainability Reporting Guidelines and a countryâ€™s strength of law enforcement and commitment towards the environment had a significant influence on the extent of carbon emission disclosures. Other variables â€“ environmental management system, environmental committee, voluntary participation in CDP programmme, corporate governance, and countryâ€™s legal origin â€“ are not significant. Considering electricity industry and Asian region are among the main contributors to the global carbon emissions, there is a pressing need for the leaders within the industry and across the countries to institute mechanisms to combat climate change including through making corporate disclosures mandatory.
Multi Objective Optimization for Turning Operation using Hybrid Extreme Learning Machine and Multi Objective Genetic Algorithm
Authors: V. Janahiraman Tiagrajah , Ahmad Nooraziah
Published: April 2019

Turning operation, a type of machining process using Computer Numerical Control (CNC) machine in which a cutting tool, typically a non-rotary tool bit, moves to describe a helix toolpath while the cylindrical metal workpiece rotates. Numerous conflicting performance functions such as maximizing material removal rate, minimizing the productâ€™s quality, maximizing the tool life and others, remains crucial for a system to optimize in order to obtain optimum benefit. The machinist is required to assign the optimal cutting parameters in CNC turning machine which have direct influence on the performance of each cutting process and machined product. It is very crucial for optimal parameters selection to maximize the performance function. A new optimisation model has been proposed in this paper. This model, uses Box Behnken Design (BBD) for design of experiment and the prediction model has been developed using Extreme Learning Machine (ELM) which is tuned using Particle Swarm Optimization. A powerful and effective, Multi Objective Genetic Algorithm (MOGA) will act as an optimizer of the developed model. Turning input parameters such as feed rate, cutting speed and depth of cut were considered as input variables and surface roughness, specific power consumption and cutting force were used as output variables. This novel approach, BBD-ELM-PSO-MOGA can predict the optimal cutting parameters as demonstrated in our case studies with less number of tunable parameters and number of experiments. Therefore, it is fast, less time consuming and easy to be implemented.Â

Published: April 2019

With the persistent development of tourism in Malaysia, tourist loyalty has become a vital topic in tourism studies. Researchers often examine this with little focus on the relations and interaction between tourist loyalty and the factors of tourism satisfaction. This study was conducted to examine the factors influencing Arab tourists’ loyalty towards tourism in Malaysia. Questionnaires were delivered conveniently to 30 Arab tourists at Kuala Lumpur International Airport (KLIA). From the overall results of this study, it can be concluded that the regression model revealed that the independent variables entered into the regression model were significant predictors of tourist loyalty. The coefficient of destination (R2) showed that about 76.00% of variance in tourist loyalty was explained by the predictor variable.

It is well known that a lot of chemical and physical processes take place on the surfaces of interaction between solid and liquid substances. These processes include a very important technological process of uranium, nickel, copper, precious metal and other solid compound extraction - in-situ leaching. In this article we will rely on the mathematical description of these complex systems proposed by A.M. Meirmanov, where the main idea is the presence of new conditions on a free (unknown) boundary between liquid and solid phases (“pore space - solid skeleton”). These conditions express the usual laws of mass conservation of mass and the development of the mathematical model describing the processes at the macroscopic level. The method proposed in the book allows us to study numerically the dependence ways of free boundary dynamics on a heterogeneous solution distribution velocity and external parameters (reagent temperature, pressure and concentration).

In this paper is to assess the mission stability and the influence of J2 effect and aerodynamic forces. To maintain the relative motion of satellites by using a feedback control law for tracking error bound in the presence of J2 perturbation. A constant relative orbit under the effect of earth oblateness and conservative forces is referred as J2 and targeting the presence of atmospheric drag. Although, Schweighart and Sedwick control strategy for satellite relative motion is considering both lift and drag forces. The simulation result shows a better performance with high accuracy than an elliptical orbit under J2 perturbation and atmospheric drag along in-track formation. The algorithm and control strategies is useful tools for analysing a future space mission.
