Authors: Gerald Cerezo Mark , Cristobal Karlo , Ferrer Angelo , Mae Moreno Helen , Ocampo Nico , Elipane Levi
Published: April 2019

This paper intends to discuss the benefits of doing lesson studies in order to improve teaching practice in Mathematics. Fifteen Grade 8 students from a private school in the National Capital Region, Philippines participated in the study. The group followed the cycle of planning the lesson, implementing, and discussing what transpired from teaching the research lesson. The lesson study is about integrating geometry in obtaining the square of a binomial. After planning the lesson and implementing what has been discussed, it has been agreed upon that the objective of the lesson has been met, and that is to relate areas in squaring a binomial. Afterwards, a post-conference discussion was done. It has been emphasized that in order to teach Mathematics effectively and efficiently, a teacher must consider and be aware of the appropriateness of a lesson given a limited amount of time. Additionally, highlighting wrong answers must be done so that students will be able to process what caused those errors and in turn they will be able to avoid those mistakes. Lastly, it is also evident that a teacher should craft his or her skills in the art of questioning. Thus, conducting lesson studies improve teaching practices in mathematics.

Authors: Tan Jian-Ding , Tiong Sieh-Kiong , Koh Siaw-Paw , Hen Chong Kok , Koay Ying-Ying
Published: April 2019

The objective of this research is to propose an Artificial Intelligent method to optimize the performance of street lightings. The method proposed in this research is by using the Electromagnetism-Like Mechanism (EM) global optimization algorithm. The proposed EM is designed to minimize the power consumption and maximize the life span of the lamps by different switching configurations and by adjusting the intensities of the lights. Simulation results indicate that the proposed algorithm can significantly reduce the power consumption of the system and drastically increase the projected life span of the lamps used. The main power savings can be found in the early stages of the graph. This shows that the evening sun rays and twilight help illuminate the street, rendering full intensity of street lights a waste. This, in turn, significantly prolonged the lifespan of the lamps used in the street lightings. It can thus be concluded that the proposed algorithm gives significantly positive impact in optimizing the performance of a street lighting system. The search speed and accuracies of the EM can be further improved by modifying or incorporating other search mechanism into the EM in future extension of the research.
Effects of Slip, Brownian Motion and Thermophoresis on Peristaltic Pumping of Nano Fluid in an Asymmetric Channel with Porous Medium
Authors: Sreenadh S. , Yasodhara G. , Sumalatha B. , N.S.Srinivas A.
Published: April 2019

This paper deals with peristaltic motion of electrically conducting nanofluid in a tapered asymmetric channel through a porous medium in presence of heat and mass transfer under the effect of slip conditions. The problem is reduced mathematically by a set of nonlinear partial differential equations which describe the conservation of mass, momentum, energy and concentration of nanoparticles. The non-dimensional form of these equations is simplified under the assumption of long wavelength and low Reynolds number. The coupled governing equations are solved analytically. The expressions for velocity, stream function, temperature and concentration are derived. The results have been presented graphically for the various interested emerging parameters and the obtained results are discussed in detail. It is observed that the magnitude of the velocity decreases in the middle of the channel while it increases near the channel walls with an increase in the non-uniform parameter  It is also noticed that the nanoparticle temperature increases with increasing thermal slip parameter . The present result coincides with the findings of Kothandapani and Prakash [19].

Authors: Yaacob Zalilawati , Abd Hamid Nadiah , Fara Shahirah Kamal Nor , Ghazali Noorlaila , Shamsuddin Roszil
Published: April 2019

The implementation of Goods and Services Tax (GST) in Malaysia has received criticism from various parties such as businesses, policy makers, professionals, business associations and individuals. Despite the rejections from these parties, the government proceeded to implement GST on 1 April 2015. Subsequently, this led to difficulties encountered by businesses, particularly the manufacturing industry in adjusting the production cost, setting prices of products, and comply with the new indirect tax structure. Hence, this study aims to explore the challenges of GST on SME batik manufacturers pertaining to business performance and compliance. A semi structured interviews were conducted on the top management and owners of SME batik manufacturer in two states of Malaysian Peninsular, namely Kelantan and Terengganu. The respondents reported that, during the era of GST, sales of their batik products decreased tremendously. In addition, they described the GST system as a complex system that affects compliance. This study solicits government’s attention on the impact of GST on Malaysian batik manufacturers. The findings suggest that it is essential for government to devise plans in reducing the financial burden of batik manufacturers and to simplify the GST mechanism in encouraging a high level of GST compliance.

Published: April 2019

Permanent magnet synchronous motors (PMSM) can be used directly in place of the induction motors (I.M) for several industrial applications since it is characterized by high efficiency, high power factor, and high power compared to I.M. However, this type of motor suffers from some abnormal conditions that result in minimizing power quality such as voltage sags, temporary disturbances, and faults within the network. In this paper, the behavior of PMSM has been studied under the above conditions in a Matlab/Simulink environment. It was noticed that such problems caused an increase in the amount of torque and current in this motor which impacted negatively on the motor speed and influenced the behavior of PMSM.
Enhancement of the Ductility Index of Concrete Pavement Using Moderate-Volume of Hybrid Fibers
Authors: Sahib Banyhussan Qais
Published: April 2019

The concrete used in highway structures such as pavements, bridge approach slabs or bridge decks are deteriorated much faster rate than other concrete structures due to environmental and traffic loads leading to sudden failure and/or more cracking potential. The present paper investigates experimentally the development of ductile concrete mixtures. Twenty-four mixtures with three types of fibers (PVA, Hocked steel fiber and Nylo-mono) were used. River sand as a fine aggregate and coarse aggregate with a maximum aggregate size of (9.5 mm) were adopted. Fly ash was used as a replacement of Portland cement with three ratios. Compressive and flexural strengths tests were achieved at different curing ages (7, 28 and 90 days) to determine the stress and ductility indexes. The results show that  due to more fly ash content there is an increase in the stress index and decrease in the ductility index for mixtures containing 1% steel and 1% PVA fibers by volume. In addition, the results demonstrated that using of Nylo-mono enhances the ductility index better than PVA. Finally, the use of 2% by volume hybrid fiber (PVA0.5+Steel.0%+Nylo-mono 0.5) achieved a ductile concrete mixture that has a ductility index nine times higher than that of plain concrete.

Published: April 2019

The article analyzes the EU rail transport directives to be implemented in Ukraine after signing the Association Agreement between the EU and Ukraine, as well as the systematic positive and negative consequences and reservations of the implementation of the directives in the Ukrainian rail transport legislation. However, bringing of rail transport to the state declared in these directives requires significant investments including foreign ones. At the same time, the investment attractiveness of the railway industry is very low. The reason for this is the unsatisfactory state of the non-current assets, low quality of transportation, unprofitable passenger transportation which requires cross-subsidization, etc. Upgrade of the transport infrastructure should be carried out with the use of the latest energy efficient technologies. There is a need to change the management principles of the railway industry as a whole. Fulfilment of implementation conditions will trigger the attraction of investments and increase of the revenue part of the budget of Ukrzaliznytsia, which in turn will increase the competitiveness of the domestic railway.

Authors: Mang Wong Jia , Rafek Abdul Ghani Md , Lai Goh Thian
Published: April 2019

Kati Formation consists of alternating layers of sandstone, siltstone and mudstone that results in non-uniform weathering. The presence of surficial features due to weathering such as iron bands, iron recementation, iron staining and lithobionts coating in an uneven distribution on the outcrop causing more complexity to the heterogeneous sedimentary rocks which are also tectonically deformed. The presence of iron recementation in highly weathered rocks causing the rock strength to be higher than the moderately weathered rocks. Thus, several laboratory tests are conducted in this study to characterise the weathered rocks which are uniaxial compressive strength (UCS), point load strength index, slake durability test, jar slake test and Schmidt hammer rebound test. Among the laboratory tests conducted in this study, slake durability index test, Id2 is the ideal test to characterise the rock samples of different weathering grades as it gives a large range of laboratory test results which is 0.3 % to 15.0 % for completely weathered, 22.0 % to 67.0 % for highly weathered, 68.0 % to 83.0 % for moderately weathered and 87.0 to 98.0 % for slightly weathered to fresh rocks. The values obtained are not affected by the uneven distribution of iron oxide present in the rock samples.

Published: April 2019

Autism is a brain development disorder that affects the patient's ability to communicate and interact with others. Most people with autism get sleep disorders. But they have some difficulty to communicate, so this problem is getting worse. The alternative that can be done is to detect sleep disorders through polysomnography. One of the test purposes is to classify the sleep stages. The doctors need a long time to process it. This paper presents an automatic sleep stage classification. The classification was based on the shallow classifiers, namely naive Bayes, k-nearest neighbor (KNN), multi-layer perceptron (MLP), and C4.5 (a type of decision tree). On the other hand, this dataset has a class imbalance problem. As a solution, this study carried out the mechanism of resampling. The results show that the use of d as a measure of the uniformity of data distribution greatly influenced the classification performance. The higher d, the more uniform the distribution of data (0 <= d <= 1). The performance with d = 1 was higher than d = 0. On the other hand, KNN was the best classifier. The highest accuracy and F-measure were 83.07 and 82.80 respectively.

Authors: BELONOZHKO Marina L. , BARBAKOV Oleg M. , ABRAMOVSKY Anton L.
Published: April 2019

For a long time, the Arctic was considered a territory not adapted for human life (“dead earth”), impassable either by water or by land due to the climate. Currently, not only scientists, but also ordinary travelers and tourists are going to the North Pole. Today, tourism in the Arctic is one of the rapidly developing areas in the past few years. Therefore, the authors studied the development of tourism in the Arctic and its impact on the environment. It has been established that the development of ecological, cultural, scientific, extreme tourism, sport hunting, fishing and cruises is relevant for the Arctic regions. It was determined that the main problem in the development of tourism in the Russian Arctic is the transport and logistics underdevelopment of the region. But, these territories are so rich in natural, cultural, historical resources that there is the possibility of developing almost all types of tourism.

The word tourism itself means traffic or traveling, hence traffic and tourism are closely related. Through traffic many areas, being them touristicaly receptive or emitive, are connected, resulting in functioning of the demand-offer occurrence. The level of traffic development therefore determines the level of touristic movement onto certain region. Construction of the roads and extention of its network enables tourists to be closer to touristic motifs and, on the other hand investors are being offered the opportunity for building receptive capacities.

Extension of the road network in Kosovo, as well as in majority of the world countries, is conditioned by physico-geographic and socio-economic factors. According to the world classification for road network density of 1000 km² lists Kosovo within a group of countries with an average stage of road development, along with some countries from the Southern Europe. This level of traffic organization is automatically being reflected into the development of tourism.

This study aims to evaluate the development level of the road network and the tourism potential offered by Kosovo; components that correlate with each other, as the development of tourism depends from the level of traffic development. In addition to the expansion and modernization of the road network, many natural and anthropogenic values are turning into important touristic sights as well. Hence, traffic in many world countries, as well as in Kosovo is reflecting positively into development of tourism as an important economic branch.

This paper is devoted to the development of a project-based approach to ensuring the competitiveness of a region’s tourism-recreation complex. The authors establish that a crucial factor is the efficiency of projects that have been implemented in regions already. It is proven that an indicator of the level of institutionalization of the public administration mechanism is the efficiency of mechanisms underlying the achievement of a balance of interests among all parties involved, which requires well-planned work on identifying the interests, coordinating those interests, and getting the partners involved in the process of implementation of the tourism project. The authors establish that currently work is being carried out in terms of putting in place mechanisms for public and private partnership, social services procurement, and social responsibility in the tourism sector. At the same time, institutionalizing the dialogue among entities associated with the mechanism for public administration of the development of a region’s tourism destination requires putting in place relevant infrastructure. The authors establish that developing a scientifically substantiated mechanism for public administration of the development of a region’s tourism destination requires analysis of the potential for developing regional destinations and factors for ensuring their competitiveness.
