Published: April 2019

The rapid advancement of the internet has given birth to many technologies. Cloud computing is one of the most emerging technology which aim to process large scale data by using the computational capabilities of shared resources. It gives support to the distributed parallel processing. Using cloud computing, we can process data by paying according to its uses which eliminates the requirement of device by individual users. As cloud computing grows, more users get attracted towards it. However, providing an efficient execution time and load distribution is a major challenging issue in the distributed systems. In our approach, weighted round robin algorithm is used and benefits of Fibonacci sequence is combined which results in better execution time than static round robin. Relevant virtual machines are chosen and jobs are assigned to them. Also, number of resources being utilized concurrently is reduced, which leads to resource saving thereby reducing the cost. There is no need to deploy new resources as resources such as virtual machines are already available.

Volatile organic compounds (VOCs) play an important role in the generation of ground level ozone and secondary organic aerosol. Most tropical countries such as Malaysia, Singapore, Indonesia, Brunei experience high ozone pollution. Beside ozone, oxides of nitrogen (NOx) from vehicular emissions also play an important role in photochemical pollution. NOx, particularly nitric oxide (NO), helps to ‘clean up’ ozone concentrations close to traffic in the ambient air of urban areas. Thus, knowledge of the chemistry of ozone-VOCs-NOx and finding the sources of VOCs are crucial to proceed with an appropriate mitigation strategy. Thus, the detection of ozone precursors and related VOCs is thoroughly discussed. This review finds that the inertness, hydrophobicity, and the effect of the artefact materials are very significant factors to be explored in the selection of the sorbent materials. In the SEA region, relative humidity is relatively high and exceeds 90% during the northeast monsoon. Thus, the hydrophobic properties of the sampling material need careful consideration. Further to the effect of relative humidity (RH), the artefact effect of the material itself is a challenge to be optimized and multi-sorbent material in a single tube could be a viable choice to minimize the effect of the unwanted signal in the spectrum.

Published: April 2019

The existing models for regulating the dynamics of the creation of science-intensive products are very fragmented; they are based on various initial data and do not allow giving a comprehensive assessment of the feasibility of RandD for the creation of science-intensive products within a given time, especially in risk.Financial and economic risk; scientific, industrial and technological risk. Taking into account these types of risk, we introduce a methodical tool. This is a complex model for regulating economic dynamics designed for a probabilistic and cost description of the dynamics and results of the creation of science-intensive products.The model provides a complex tech-economic evaluation of projects to develop high-tech products in risk. This model has a universal character and can be used in all branches of economics of a technologically developed country. In practice, this complex model can be useful at the stage of selection of competing organizations designs with the purpose of evaluating their capacity to implement projects, as well as at the stage of adjusting the funding plan and cost estimates for the creation of science-intensive products.This model may be used in planning bodies to assess the capabilities of design organizations in the implementation of orders for the creation of science-intensive products.

Authors: Evgenevna Frolova Evgenia , Mikhailovna Belikova Ksenia , Vladimirovna Badaeva Natalia
Published: April 2019

The development of transnational corporations (TNC) raises the question of an effective system of organization management, in particular, in countries - members of the BRICS. The results of the study showed the use of a collective labor contract in organizations in India, China, South Africa is not widespread. Regulation of social and labor relations is limited to national features, mentality, traditions. For example, in China workers, due to the prevailing attitude and philosophy, do not seek to use a collective labor contract to regulate the relations with the employer. Based on a number of reasons shown in the article, the authors consider that most probably no major changes related to the regulation of labor relations in these countries will occur in the near future.

The article considers the main aspects that characterize the economic security system of the Eurasian Economic Union (EAEU) and means to ensure economic security that contribute to increasing economic potential and to creating conditions for the effective development of integration processes. The authors investigated the main documents of the Eurasian Economic Commission (EEC), a constantly acting regulating body of the EAEU, and developed recommendations for creating unified strategies of the economic security of the Eurasian Economic Union that can be implemented in the system of risk management that, in turn, is based on the controlling toolkit. In the process of the research it was determined that the political aspect alone is not enough for the preservation and effective development of the Eurasian Economic Union as common economic interests and possible effects from their implementation are the crucial components of viability of any integration union including the EAEU country members. In this regard the formation of the system of economic security of the integration union of Russia, Belarus, Kazakhstan, Armenia and Kyrgyzstan is a relevant issue. In order to contribute to the integration of the countries of the Eurasian Economic Union that is based on the geopolitical aspect it is necessary to ensure economic security which determines both the theoretical and practical significance of the study. At the same time such integration would promote the unification of the EAEU countries that are different in the level of their socio-economic development.

Within the modern economic environment, Russia has faced a number of problems. In this regard, it becomes important for state authorities to focus on the issues of ensuring the state’s financial security. The article aims to define the method of as-sessing the state’s financial security level. The following scientific research methods are used in the paper: the deductive method is used to comprehend the general theories, the essence and the meaning of the state’s financial security; the method of analysis is used to describe the theory and practice of the state’s financial security; and the method of synthesis is used to obtain the summarized results of the research, to formulate conclusions and general statements regarding the problems of the state’s financial security and the methods of its assessment. The scientific justification of the identified problems and the development of the theory and method-ology is carried out based on the principles of the system approach. The system of financial security indicators that reflects the criti-cal points of the financial system and the financial relations in the Russian Federation must comprise the security indicators of the budget and tax system, the banking and credit system, and the currency and monetary system. It should be noted that in order to determine threats and destabilizing factors in advance, a comprehensive system of financial security indicators should be formed and adequate threshold limit values for those should be calculated. It should be emphasized that implicit usage of other authors’ methods to calculate the financial security level, as well as adhering to benchmarks only are not sufficient to conduct a comprehensive analy-sis of the state’s financial security.

Published: April 2019

In the past few years, network requirements have been changing frequently as the amount of data traffic increasing exponentially so it is difficult to utilize the full capacity of network resources. Software Defined Networking (SDN) is emerging as a new networking technology which decouples the control plane from the data plane in the network devices. Separation of control and data plane allows a network administrator a better control over network management and also enables new development through network programmability. Presently Open-Flow is the most popular SDN protocol which provides communication between network devices and controller. In this paper, the Round Robin algorithm is compared with the Dynamic load balancing algorithm using the OpenFlow protocol in SDN under varying load conditions of TCP and UDP traffic. Experimental analysis shows that the dynamic load balancing strategy works better than the Round Robin load balancing.

Published: April 2019

Wireless Sensor Network (WSN) has an enormous scope of utilizations in detecting different parameters such as temperature, pressure, sound, pollution, etc. The sensed data in each sensor node are a valuable one. To communicate the information to the base station for further processing, a lot of strategies are available. Each sensor senses the data in different sampling rate depending upon the sudden raise in the sensing parameters. Data communication to the base station is very critical due to the dynamicity of the environment during the stipulated time.The sensed data should reach the base station before the data becomes invalid due to the violation of the deadline. In order to avoid deadline violation so that the sensed data becomes useless, this paper proposing a novel data collection algorithm based on the popular Earliest Deadline First (EDF) scheduling algorithm. The various simulation parameters are taken into account to verify the performance of the proposed method and the result shows that it achieves high throughput, low delay, high Packet Delivery Ratio (PDR) and low energy consumption.

Authors: G. Dande Rupali , Amol D. Potgantwar Dr , Amol D. Potgantwar Dr
Published: April 2019

Secure Data sharing is a major issue of concern in cloud computing. CPABE is well known encryption technique for dealing with the problem of data security over network. Most of the files have multilevel access hierarchy especially in health care and military domain. The hierarchy structure and revocation of shared files is not scrutinized in CP-ABE.  In this paper, experts proposed the enhanced method of encryption to support the direct revocation, in which sender specifies the revocation list during encryption of cipher text so that the problem of releasing periodic key update information in indirect revocation is vanished. Here the direct revocation mechanism and file access based hierarchy are merged to get enhanced CPABE. The multilevel access structure is integrated and merged with encrypted files with current access structure. Along with revocation, aim is also to improve the overall system performance with respect to encryption time and decryption time. Experimental result shows the enhanced performance of the proposed system as compared to existing system with respect to time and security constraints. Moreover the scheme is secure under the standard security assumption. Finally, based on the research, it gives forthcoming research direction to expand and implement the scheme in any practical application where security is main concern by proper coalition of the proposed technologies.

Authors: Hossein Baghdadi Amir , Fazilah Mohamad Selamat Nor , Sajuri Zainuddin , Hossein Kokabi Amir
Published: April 2019

Weight reduction is one of the most concerning issues of automotive and aircraft industries in reducing fuel consumption. Magnesium (Mg) alloys are the lightest alloys which can be used in the structure due to low density and high strength to weight ratio. Developing a reliable joining process of magnesium alloys is required due to limited ductility and low workability at room temperature. Friction stir welding (FSW) is a solid-state welding process that can be performed to produce sound joints in magnesium alloys. Researchers have performed investigations on the effect of rotation and travel speeds in FSW of AZ31B magnesium alloy. However, there is lack of study on the FSW parameters, i.e. travel speed below 50 mm/min and rotation speed lower than 1000 rpm. In this research, FSW of AZ31B magnesium alloy was performed at a constant rotation speed of 700 rpm and varied travel speeds below 50 mm/min. The results showed the development of finer grain size in stir zone with increasing of welding travel speed from 20 mm/min to 40 mm/min. It was found that the finer grain size improved the mechanical properties while maintaining the elongation at different welding parameters.

Authors: Fauzan Norsiah , Mazlina Ghazali Nor
Published: April 2019

This article reports on the differences between the physiological response of the brain between athletes and non-athletes by using Quantitative Electroencephalography (QEEG). EEG waves were observed using qEEG and analysis were compared between the two groups.  This research involved 41 undergraduates of Universiti Malaysia Sarawak (UNIMAS). The qEEG recordings were made during the Eyes opened, Eyes Closed, and Stroop task conditions to find out the dominant wave during each of the conditions in different region of the brain. The results revealed higher EEG Delta and Beta1 at frontal region (Fp1, Fp2), somatosensory, (C3, P4) and visual spatial area (P3, P4). Delta, Beta and Gamma wave were dominant while the participants were performing the Stroop Task. Coupling of delta and beta oscillations might be due to the athletes’ anxiety during the Stroop task.  In Eyes Closed state, delta and alpha wave were dominant at the fronto-parietal attention network area. This study contributes to the development of training protocol for neurofeedback training for athletes in preparation for training of peak performance in any sports activity. It is recommended that extensive analysis should be done on the interaction of delta-gamma oscillations in different parts of the brain to find out its implication on attention and emotion during the cognitive process.

Published: April 2019

Overhead high voltage transmission conductors used worldwide are produced in several configurations. A multi-strand conductor of the type ACSR330 is typically used for 275 kV overhead transmission lines. The conductor is composed of 7 inner strands of Ultra High Strength Galvanized Steel for the mechanical support of the conductor and 26 strands of high conductivity Aluminum wires meant for power transfer over long distances. During the use, weather conditions and power fluctuations tend to degrade the properties of these conductors. In the present work, study of the state of galvanization and oxidation of an ACSR330 conductor is undertaken with a view to understand the effectiveness of the loss in corrosion protection and changes in the zinc coating on the galvanized steel strands after use for 25 to 30 years. The Scanning Electron Microscopy (SEM), X Ray Diffraction (XRD) and Energy Dispersive Analysis through X rays (EDAX) provide a very useful insight into the state of the conductor and gives important information to the strategic decision maker, whether or not to replace the conductor. It was observed in the present study that the zinc coating diffuses inside the steel strand under temperature and time effect. This unique study on the used conductors also reveals that the morphology of the coating and its interface structure changes significantly compared to an unused conductor of the same age.

Published: April 2019

Chromium pollution has been an increasing concern worldwide because of its high toxicity and carcinogenic properties, and it requires an efficient purification technique. In this study, adsorbent beads containing polyvinyl alcohol (PVA) and sodium alginate were prepared by crosslinking with boric acid and calcium chloride for adsorbent of the hexavalent chromium [Cr (VI)]. Batch adsorption studies were conducted to evaluate Cr (VI) adsorption rates of PVA-alginate beads from aqueous solution under ultraviolet (UV) light illumination. The surface morphology and elemental composition of beads were examined using field emission scanning electron microscopy (FESEM) and energy dispersive spectrometer (EDS), respectively. This study revealed that the Cr (VI) adsorption rates increased remarkably with dosages of PVA and sodium alginate. This occurred mainly due to the increasing number of the active sites for adsorption. The results revealed that adsorbent beads with 12 g of PVA and 2.5 g sodium alginate beads exhibited superior Cr (VI) adsorption efficiency at which it is completely removed after 1.5 hours. The findings of this study indicate that PVA-sodium alginate beads are a viable option for Cr (VI) removal from industrial wastewater.Â Â

Solid waste management is considered as one of the complex and dynamics problems worldwide due to rapid population, changing life style, urbanization process towards sustainable development and uncontrollable increment in solid waste generation. An efficient performance of solid waste management is depending on systematic strategic planning. The aim of this paper is to develop an integrated dynamical model to simulate the complexity of solid waste management in Malaysia. System dynamics as one of optimization methodology is applied in order to illustrate the continuous process in solid waste management Malaysia. As a result, an increasing trend of solid waste generation over time. By 2025, it is forecasted that total waste will be more than 15 million tonnes. Based on developed proposed model, the main factor to solid waste generation is population. However, in order to reduce the total solid waste, we cannot simply reduce the population Therefore; further actions are needed in order to reduce the total solid waste generation. The proposed model is capable of assisting the decision maker to determine the effectiveness of solid waste management practices especially in strategies planning and system design improvement.Â Â

In students’ learning process, self-efficacy plays an important part. In Malaysia, there are a number of researches on students’ self-efficacy. However, none of the studies focuses on undergraduate students’ computer self-efficacy from the rural areas. This article presents a quantitative research on undergraduate students’ perceived computer self-efficacy. A total of 128 first semester undergraduate students participated in the survey, employing a 27-item questionnaire measuring computer self-efficacy. The items were pilot-tested before being administered to the respondents. Outcome of the research show that computer self-efficacy level is high for basic and advanced skills. The result of the research shows that rural community has accepted the ICT as part of their lifestyle.

With the rapid growth of technology, nowadays people are using Information Communication Technology (ICT) as a tool in all aspects of life. Malaysia towards Vision 2020 has implemented many initiatives in ICT transformation for community including students from the rural areas. This study is conducted to examine computer level of anxiety and skills amongst undergraduate students from rural areas at selected private higher institutions in Negeri Sembilan. The study was done through distribution of 128 questionnaires to year one students from non-computing programs who are enrolled computer literacy subject at the institutions. The findings of this study show that the level of anxious on using computer amongst undergraduate students is low. The students also show a good level of computer skills but low level of web site development skills. It is recommended that any web site development training for rural areas students should take into consideration for student’s enhancement and career. Future study on web site development skills amongst undergraduate students from rural areas at higher institution also is recommended.

The copula method has been popular among researchers, especially in measuring the overall dependence and extreme dependence of multivariate data. Many copula studies have been focusing on examining the correlation of bivariate daily, monthly or weekly returns to explain the co-movement between financial markets and possible financial implications on portfolio management. Differently from past studies, this paper investigates whether different frequency of bivariate data (daily and weekly returns) possesses different dependence structures. The data from Kuala Lumpur Composite Index (KLCI) and Bursa Malaysia Hijrah Shariah Index (FBMHS) for the sample period of 2008 Q1 to 2017 Q1 are used for studying the dependency. The findings from this study reveal that both daily and weekly bivariate returns have the same dependence structure but different degree of dependence. Bivariate weekly returns showed stronger dependence compared to bivariate daily returns. This paper also highlights the statistical properties of weekly and daily data. The evidence from this research draws inferences for further study that lower frequency data such as monthly or quarterly returns data may have higher degree of dependence while higher frequency data may have lower degree of dependence and different copula structure.

Claim risk is a payment made by the insurance company to the policyholder. Actuaries in insurance companies should be able to measure and control the risk of claims, in order to avoid losses to insurance companies. In this paper we analyze the Geometric-Gamma Collective Modified Value-at-Risk model in life insurance risk. In this research, there is a development of claim risk measure called Collective Modified Value-at-Risk, which is an extension of Collective Risk model. This Collective Modified Value-at-Risk model requires estimation of the mean, variance, skewness, and kurtosis parameters. The result of this research, is that the extent of this model can be applied to the risk of claims amount of non-normal distributed. Thus, the Collective Modified Value-at-Risk model can serve as one of the statistical alternatives for measuring the risk of claims on life insurance.Â Â

Published: April 2019

The purpose of this study is to calibrate undergraduatesâ€™ well-being. 378 engineering undergraduates provide responses for this study. An 8-item Flourishing Scale is employed to gauge the responses using the Rasch model analysis. Results show that one item need to be dropped since they did not meet the Rasch modelâ€™s expectations. Analysis on the remaining seven items showed that the undergraduates were least able to contribute to the happiness and well-being of others. In contrast they somewhat have positive well-being by endorsing that they have a purposeful and meaningful life. In addition, we discuss how to the findings might be helpful for university stakeholders to plan effective interventions for the undergraduates.Â
