This state arises as a problem which affects the society wholly such as the supply of food stuffs that are necessary for an individual to perform his physiological and biological functions, their amount, compound, their effects on health and distribution by individuals. This study was conducted in order to determine the sensitivities and criteria of people, who have different socio-economic backgrounds and live in Süleymanpasa Town of Tekirdag City, in their preference of food stuffs. The research data were collected by means of Interview Technique with individuals within the scope of the study (300) and applying surveys with convenience sampling. According to the research results, quality appears in the first rank among the factors by which consumers are affected while buying food stuffs. Consumers stated that they try to be careful with not buying food sold outdoors. The most preferred food among the ones being sold outdoor were found to be breakfast food. Also, food stuff which consumers become the most selective for while buying was determined to be meat and meat products. Due to general knowledge about the food stuff consumed in human nutrition may affect their health negatively; consumers expressed that they are very relevant with their diets and this circumstances affects their purchase preferences.   <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=consumption" title="consumption">consumption</a>, <a href="https://publications.waset.org/abstracts/search?q=food%20safety" title=" food safety"> food safety</a>, <a href="https://publications.waset.org/abstracts/search?q=consumer%20behaviour" title=" consumer behaviour"> consumer behaviour</a>, <a href="https://publications.waset.org/abstracts/search?q=purchase%20preferences" title=" purchase preferences"> purchase preferences</a> </p> <a href="https://publications.waset.org/abstracts/50917/determining-food-habits-in-suleymanpasa-town-of-tekirdag-city-turkey" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/50917.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">320</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">49</span> The Impact of Virtual Learning Strategy on Youth Learning Motivation in Malaysian Higher Learning Instituitions</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Hafizah%20Harun">Hafizah Harun</a>, <a href="https://publications.waset.org/abstracts/search?q=Habibah%20Harun"> Habibah Harun</a>, <a href="https://publications.waset.org/abstracts/search?q=Azlina%20Kamaruddin"> Azlina Kamaruddin</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Virtual reality has become a powerful and promising tool in education because of their unique technological characteristics that differentiate them from the other ICT applications. Despite the numerous interpretations of its definition, virtual reality can be concisely and precisely described as the integration of computer graphics and various input and display technologies to create the illusion of immersion in a computer generated reality. Generally, there are two major types based on the level of interaction and immersive environment that are immersive and non-immersive virtual reality. In the study of the role of virtual reality in built environment education, Horne and Thompson were reported as saying that the benefits of using visualization technologies were seen as having the potential to improve and extend the learning process, increase student motivation and awareness, and add to the diversity of teaching methods. Youngblut reported that students enjoy working with virtual worlds and this experience can be highly motivating. The impact of virtual reality on youth learning in Malaysia is currently not well explored because the technology is still not widely used here. Only a handful of the universities, such as University Malaya, MMU, and Unimas are applying virtual reality strategy in some of their undergraduate programs. From the literature, it has been identified that there are several virtual reality learning strategies currently available. Therefore, this study aims to investigate the impact of Virtual Reality strategy on Youth Learning Motivation in Malaysian higher learning institutions. We will explore the relationship between virtual reality (gaming, laboratory, simulation) and youth leaning motivation. Another aspect that we will explore is the framework for virtual reality implementation at higher learning institution in Malaysia. This study will be carried out quantitatively by distributing questionnaires to respondents from sample universities. Data analysis are descriptive and multiple regression. Researcher will carry out a pilot test prior to distributing the questionnaires to 300 undergraduate students who are undergoing their courses in virtual reality environment. The respondents come from two universities, MMU CyberJaya and University Malaya. The expected outcomes from this study are the identification of which virtual reality strategy has most impact on students’ motivation in learning and a proposed framework of virtual reality implementation at higher learning. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=virtual%20reality" title="virtual reality">virtual reality</a>, <a href="https://publications.waset.org/abstracts/search?q=learning%20strategy" title=" learning strategy"> learning strategy</a>, <a href="https://publications.waset.org/abstracts/search?q=youth%20learning" title=" youth learning"> youth learning</a>, <a href="https://publications.waset.org/abstracts/search?q=motivation" title=" motivation"> motivation</a> </p> <a href="https://publications.waset.org/abstracts/8627/the-impact-of-virtual-learning-strategy-on-youth-learning-motivation-in-malaysian-higher-learning-instituitions" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/8627.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">389</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">48</span> Solution of Logistics Center Selection Problem Using the Axiomatic Design Method</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Fulya%20Zaral%C4%B1">Fulya Zaralı</a>, <a href="https://publications.waset.org/abstracts/search?q=Harun%20Resit%20Yazgan"> Harun Resit Yazgan</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Logistics centers represent areas that all national and international logistics and activities related to logistics can be implemented by the various businesses.

The main virtue of the microwave technique is cost-effective, time saving and simple handling procedure. Castor beans was chosen because of its high content in fatty acid, especially ricinoleic acid. The purpose of this research is to extract the castor oil by using the microwave assisted extraction (MAE) using ethanol as solvent and to investigate the influence of extraction time on castor oil yield and to characterize the main composition of the produced castor oil by using the GC-MS. It was found that there is a direct dependence between the oil yield and the time of extraction as it increases from 45% to 58% as the time increase from 10 min to 60 min. The major components of castor oil detected by GC-MS were ricinoleic acid, linoleic acid and oleic acid. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=microwave%20assisted%20extraction%20%28MAE%29" title="microwave assisted extraction (MAE)">microwave assisted extraction (MAE)</a>, <a href="https://publications.waset.org/abstracts/search?q=castor%20oil" title=" castor oil"> castor oil</a>, <a href="https://publications.waset.org/abstracts/search?q=ricinoleic%20acid" title=" ricinoleic acid"> ricinoleic acid</a>, <a href="https://publications.waset.org/abstracts/search?q=linoleic%20acid" title=" linoleic acid"> linoleic acid</a> </p> <a href="https://publications.waset.org/abstracts/10844/microwave-assisted-extraction-mae-of-castor-oil-from-castor-bean" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/10844.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">503</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">45</span> The Effect of Type of Nanoparticles on the Quenching Process</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Dogan%20Ciloglu">Dogan Ciloglu</a>, <a href="https://publications.waset.org/abstracts/search?q=Abdurrahim%20Bolukbasi"> Abdurrahim Bolukbasi</a>, <a href="https://publications.waset.org/abstracts/search?q=Harun%20Cifci"> Harun Cifci</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this study, the experiments were carried out to determine the best coolant for the quenching process among water-based silica, alumina, titania and copper oxide nanofluids (0.1 vol%).

This is because on-time shipments are vital for lowering cost and increasing customers’ satisfaction. This paper addresses the single machine scheduling problem with the objective of minimizing the number of tardy jobs. The only known information is the lower and upper bounds for processing times, and deterministic job due dates. A dominance relation is established, and an algorithm is proposed. Several heuristics are generated from the proposed algorithm. Computational analysis indicates that the performance of one of the heuristics is very close to the optimal solution, i.e., on average, less than 1.5 % from the optimal solution. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=single%20machine%20scheduling" title="single machine scheduling">single machine scheduling</a>, <a href="https://publications.waset.org/abstracts/search?q=number%20of%20tardy%20jobs" title=" number of tardy jobs"> number of tardy jobs</a>, <a href="https://publications.waset.org/abstracts/search?q=heuristi" title=" heuristi"> heuristi</a>, <a href="https://publications.waset.org/abstracts/search?q=lower%20and%20upper%20bounds" title=" lower and upper bounds"> lower and upper bounds</a> </p> <a href="https://publications.waset.org/abstracts/21639/single-machine-scheduling-problem-to-minimize-the-number-of-tardy-jobs" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/21639.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">555</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">43</span> Prospective Analysis of Micromobility in the City of Medellín</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sa%C3%BAl%20Rivero">Saúl Rivero</a>, <a href="https://publications.waset.org/abstracts/search?q=Estefanya%20Mar%C3%ADn"> Estefanya Marín</a>, <a href="https://publications.waset.org/abstracts/search?q=Katherine%20Bola%C3%B1o"> Katherine Bolaño</a>, <a href="https://publications.waset.org/abstracts/search?q=Elena%20Ur%C3%A1n"> Elena Urán</a>, <a href="https://publications.waset.org/abstracts/search?q=Juan%20Yepes"> Juan Yepes</a>, <a href="https://publications.waset.org/abstracts/search?q=Andr%C3%A9s%20Cossio"> Andrés Cossio</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Medellín is the Colombian city with the best public transport systems in the country, which is made up of two metro lines, five metrocables, two BRT-type bus lines, and a tram. But despite the above, the Aburrá Valley, the area in which the city is located, has about 3000 km of roads, which for the existing population of 3.2 million inhabitants, gives an indicator of 900 meters of road per 1000 inhabitants, which is lower than the country's average, which is approximately 3900 meters. In addition, given that in Medellín, there is approximately one vehicle for every three inhabitants, the problems of congestion and environmental pollution have worsened over the years. In this sense, due to the limitations of physical space, the low public investment in road infrastructure, it is necessary to opt for mobility alternatives according to the above. Among the options for the city, there is what is known as micromobility. Micromobility is understood to be those small and light means of transport that are used for short distances, that use electrical energy, such as skateboards and bicycles. Taking into account the above, in this work, the current state and future of micromobility in the city of Medellín were analyzed, carrying out a prospective analysis, supported by a PEST analysis, but also of the crossed impact matrices; of influence and dependence; and the technique of the actor's game. The analysis was carried out for two future scenarios: one normal and one optimistic. Result of the analysis, it was determined that micromobility as an alternative social practice to mobility in the city of Medellín has favorable conditions since the local government has adopted strategies such as the Metropolitan Bicycle Master Plan of Valle de Aburrá and the plan " Bicycle paths in the city: more public spaces for life,” where a projection of 400 kilometers of bicycle paths was estimated by the year 2030, as for that same year it is expected that 10% of all trips in the region will be in bike mode. The total trip indicator is an achievable goal, while that of the number of kilometers of bike paths would be close to being met. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=electric%20vehicles" title="electric vehicles">electric vehicles</a>, <a href="https://publications.waset.org/abstracts/search?q=micromobilty" title=" micromobilty"> micromobilty</a>, <a href="https://publications.waset.org/abstracts/search?q=public%20transport" title=" public transport"> public transport</a>, <a href="https://publications.waset.org/abstracts/search?q=sustainable%20transport" title=" sustainable transport"> sustainable transport</a> </p> <a href="https://publications.waset.org/abstracts/143627/prospective-analysis-of-micromobility-in-the-city-of-medellin" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/143627.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">201</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">42</span> An Improved Genetic Algorithm for Traveling Salesman Problem with Precedence Constraint</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=M.%20F.%20F.%20Ab%20Rashid">M.

The existing algorithms to solve TSPPC cost large computational time to find the optimal solution. The purpose of this paper is to present an efficient genetic algorithm that guarantees optimal solution with less number of generations and iterations time. Unlike the existing algorithm that generates priority factor as chromosome, the proposed algorithm directly generates sequence of solution as chromosome. As a result, the proposed algorithm is capable of generating optimal solution with smaller number of generations and iteration time compare to existing algorithm. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=traveling%20salesman%20problem" title="traveling salesman problem">traveling salesman problem</a>, <a href="https://publications.waset.org/abstracts/search?q=sequencing" title=" sequencing"> sequencing</a>, <a href="https://publications.waset.org/abstracts/search?q=genetic%20algorithm" title=" genetic algorithm"> genetic algorithm</a>, <a href="https://publications.waset.org/abstracts/search?q=precedence%20constraint" title=" precedence constraint"> precedence constraint</a> </p> <a href="https://publications.waset.org/abstracts/15486/an-improved-genetic-algorithm-for-traveling-salesman-problem-with-precedence-constraint" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/15486.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">560</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">41</span> Optimizing of Machining Parameters of Plastic Material Using Taguchi Method</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Jumazulhisham%20Abdul%20Shukor">Jumazulhisham Abdul Shukor</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohd.%20Sazali%20Said"> Mohd.

Therefore, poor selection of this parameter during the machine design phase causes the air-gap magnetic flux density to be distorted. Thus, it causes noise, torque fluctuation, and losses in the induction motor. On the other hand, the change in rotor bar dimensions will change the resistance of the conductor, so the current will be affected. Therefore, the increase and decrease of rotor bar current affect operation, starting torque, and efficiency. The aim of this study is to examine the effect of rotor bar dimensions on the electromagnetic performance criteria of the induction motor. Modeling of the induction motor is done by the finite element method (FEM), which is a very powerful tool. In FEM, the results generally focus on performance criteria such as torque, torque fluctuation, efficiency, and current. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=induction%20motor" title="induction motor">induction motor</a>, <a href="https://publications.waset.org/abstracts/search?q=finite%20element%20method" title=" finite element method"> finite element method</a>, <a href="https://publications.waset.org/abstracts/search?q=optimization" title=" optimization"> optimization</a>, <a href="https://publications.waset.org/abstracts/search?q=rotor%20bar" title=" rotor bar"> rotor bar</a> </p> <a href="https://publications.waset.org/abstracts/151100/optimization-of-three-phase-squirrel-cage-induction-motor" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/151100.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">126</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">39</span> Implied Adjusted Volatility by Leland Option Pricing Models: Evidence from Australian Index Options</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mimi%20Hafizah%20Abdullah">Mimi Hafizah Abdullah</a>, <a href="https://publications.waset.org/abstracts/search?q=Hanani%20Farhah%20Harun"> Hanani Farhah Harun</a>, <a href="https://publications.waset.org/abstracts/search?q=Nik%20Ruzni%20Nik%20Idris"> Nik Ruzni Nik Idris</a> </p> <p class="card-text"><strong>Abstract:</strong></p> With the implied volatility as an important factor in financial decision-making, in particular in option pricing valuation, and also the given fact that the pricing biases of Leland option pricing models and the implied volatility structure for the options are related, this study considers examining the implied adjusted volatility smile patterns and term structures in the S&P/ASX 200 index options using the different Leland option pricing models.

BOD and COD are two main parameters to justify quality of wastewater. A ratio, BOD:COD can usually be established between the two analytical methods once COD and BOD value has been gathered. This ratio plays a vital role to determine appropriate strategy in wastewater treatment. A non-adiabatic microfiber sensor was formed by tapering the SMF to generate evanescent field where sensitive to perturbation of sensing medium. Because difference ratio BOD and COD contain in solution, this may induced changes of effective refractive index between microfiber and sensing medium. Attenuation wavelength shift to right with 0.5 nm and 3.5 nm while BOD:COD equal to 0.09 and 0.18 respectively. Significance difference wavelength shift may relate with the biodegradability of analyte. This proposed sensor is compact, reliable and feasible to determine the BOD:COD.

Although MOOCs offer many appreciated learning experiences to learners from various universities and institutions, they have considerably higher dropout rates than traditional education. Only about 10% of the learners who enroll in MOOCs actually complete the course. In this case, perceptions of participants and a comprehensive analysis of MOOCs have become an essential part of the research in this area. This study aims to explore the MOOCs in detail for better understanding its content, purpose and primarily drop out issues. The researcher conducted an online questionnaire to get perceptions of graduate students on their learning experiences in MOOCs and arranged a semi- structured oral interview with some participants. The participants are Turkish graduate level students doing their MA and Ph.D. in various programs. The findings show that participants are more likely to drop out courses due to lack of time and lack of pressure. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=distance%20education" title="distance education">distance education</a>, <a href="https://publications.waset.org/abstracts/search?q=MOOCs" title=" MOOCs"> MOOCs</a>, <a href="https://publications.waset.org/abstracts/search?q=drop%20out" title=" drop out"> drop out</a>, <a href="https://publications.waset.org/abstracts/search?q=perception%20of%20graduate%20students" title=" perception of graduate students"> perception of graduate students</a> </p> <a href="https://publications.waset.org/abstracts/64464/turkish-graduate-students-perceptions-of-drop-out-issues-in-massive-open-online-courses" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/64464.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">240</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">36</span> Role of Non-Renewable and Renewable Energy for Sustainable Electricity Generation in Malaysia</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Hussain%20Ali%20Bekhet">Hussain Ali Bekhet</a>, <a href="https://publications.waset.org/abstracts/search?q=Nor%20Hamisham%20Harun"> Nor Hamisham Harun</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The main objective of this paper is to give a comprehensive review of non-renewable energy and renewable energy utilization in Malaysia, including hydropower, solar photovoltaic, biomass and biogas technologies. Malaysia mainly depends on non-renewable energy (natural gas, coal and crude oil) for electricity generation. Therefore, this paper provides a comprehensive review of the energy sector and discusses diversification of electricity generation as a strategy for providing sustainable energy in Malaysia. Energy policies and strategies to protect the non-renewable energy utilization also are highlighted, focusing in the different sources of energy available for high and sustained economic growth. Emphasis is also placed on a discussion of the role of renewable energy as an alternative source for the increase of electricity supply security. It is now evident that to achieve sustainable development through renewable energy, energy policies and strategies have to be well designed and supported by the government, industries (firms), and individual or community participation. The hope is to create a positive impact on sustainable development through renewable sources for current and future generations. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Malaysia" title="Malaysia">Malaysia</a>, <a href="https://publications.waset.org/abstracts/search?q=non-renewable%20energy" title=" non-renewable energy"> non-renewable energy</a>, <a href="https://publications.waset.org/abstracts/search?q=renewable%20energy" title=" renewable energy"> renewable energy</a>, <a href="https://publications.waset.org/abstracts/search?q=sustainable%20energy" title=" sustainable energy"> sustainable energy</a> </p> <a href="https://publications.waset.org/abstracts/54485/role-of-non-renewable-and-renewable-energy-for-sustainable-electricity-generation-in-malaysia" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/54485.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">402</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">35</span> Two Stage Assembly Flowshop Scheduling Problem Minimizing Total Tardiness</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ali%20Allahverdi">Ali Allahverdi</a>, <a href="https://publications.waset.org/abstracts/search?q=Harun%20Aydilek"> Harun Aydilek</a>, <a href="https://publications.waset.org/abstracts/search?q=Asiye%20Aydilek"> Asiye Aydilek</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The two stage assembly flowshop scheduling problem has lots of application in real life.

Different dominance relations are developed and several algorithms are proposed. Extensive computational experiments are conducted to evaluate the proposed algorithms. The computational experiments have shown that one of the algorithms performs much better than the others. Moreover, the experiments have shown that the best performing algorithm performs much better than the best existing algorithm for the case of zero setup times in the literature. Therefore, the proposed best performing algorithm not only can be used for problems with separate setup times but also for the case of zero setup times. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=scheduling" title="scheduling">scheduling</a>, <a href="https://publications.waset.org/abstracts/search?q=assembly%20flowshop" title=" assembly flowshop"> assembly flowshop</a>, <a href="https://publications.waset.org/abstracts/search?q=total%20tardiness" title=" total tardiness"> total tardiness</a>, <a href="https://publications.waset.org/abstracts/search?q=algorithm" title=" algorithm"> algorithm</a> </p> <a href="https://publications.waset.org/abstracts/48248/two-stage-assembly-flowshop-scheduling-problem-minimizing-total-tardiness" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/48248.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">344</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">34</span> Biomolecular Interaction of Ruthenium(II) Polypyridyl Complexes</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=S.%20N.%20Harun">S.

The previously reported complexes [Ru(bpy)2L]2+ and [Ru(phen)2L]2+ were also prepared. All complexes were characterized by elemental analysis, 1H-NMR spectroscopy, ESI-Mass spectroscopy and FT-IR spectroscopy. The photophysical properties were analyzed by UV-Visible spectroscopy and fluorescence spectroscopy. [Ru(dppz)2(PIP)]2+ and [Ru(dppz)2(p-HPIP)]2+ displayed ‘molecular light-switch’ effect as they have high emission in acetonitrile but no emission in water. The cytotoxicity of all complexes against cancer cell lines Hela and MCF-7 were investigated through standard MTT assay. [Ru(dppz)2(PIP)]2+ showed moderate toxicity on both MCF-7 and Hela with IC50 of 37.64 µM and 28.02 µM, respectively. Interestingly, [Ru(dppz)2(p-HPIP)]2+ exhibited remarkable cytotoxicity results with IC50 of 13.52 µM on Hela and 11.63 µM on MCF-7 cell lines which are comparable to the infamous anti-cancer drug, cisplatin.

The detection system requires an optical sensing system, microfluidic device and biological reagent. Although, the biosensors are available in the market, a label free and a lab-on-chip approach will promote a flexible solution. As a preliminary study of microorganism detection, three mechanisms such as Total Internal Reflection (TIR), Micro Fluidic Channel (MFC) and magnetic-electric field propagation were study and simulated. The objective are to identify the TIR angle, MFC parabolic flow and the wavelength for the microorganism detection. The simulation result indicates that evanescent wave is achieved when TIR angle > 42°, the corner and centre of a parabolic velocity are 0.02 m/s and 0.06 m/s respectively, and a higher energy distribution of a perfect electromagnetic scattering with dipole resonance radiation occurs at 500 nm. This simulation is beneficial to determine the components of the microorganism detection system that does not rely on classical microbiological, immunological and genetic methods which are laborious, time-consuming procedures and conﬁned to specialized laboratories with expensive instrumentation equipment. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=microorganism" title="microorganism">microorganism</a>, <a href="https://publications.waset.org/abstracts/search?q=microfluidic" title=" microfluidic"> microfluidic</a>, <a href="https://publications.waset.org/abstracts/search?q=total%20internal%20reflection" title=" total internal reflection"> total internal reflection</a>, <a href="https://publications.waset.org/abstracts/search?q=lab%20on%20chip" title=" lab on chip"> lab on chip</a> </p> <a href="https://publications.waset.org/abstracts/82785/finite-element-simulation-for-preliminary-study-on-microorganism-detection-system" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/82785.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">277</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">32</span> New Tools and New Ways; Changing the Nature of Leadership and Future Challenges</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Harun%20Ozdemirci">Harun Ozdemirci</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Complexity and chaos are the characteristics of our new world today.

But how it will occur and at which direction it will be managed or directed? What kind of abilities and attitudes make leader compatible with this ever-changing and ambigous environment? Leader who will lead in the future must have some special skillls. But how can we develop these skills and behaviours? What must be the mindset of a future leader? This paper searchs for answers of some of these questions. But asking questions is more important than giving answers to them. Innovation and creativity have been at the centerpiece of our lives for some years. But we don’t know how to manage and how to tackle with the challenges come up with this new situation. This new world order compel us to take some new positions against new employees who have different types of lives and habits, new productivity processes, new adversaries… Future environment will not be the same as we experience before. So, our responses to this new environment can not be the same as our predecessors gave.

Bright–dark pulses could be achieved when the laser works in the passively mode-locking regime and the net group velocity dispersion is quite anomalous. The EDFL starts to generate a bright pulse train with degenerated dark pulse at the mode-locking threshold pump power of 35.09 mW by manipulating the polarization states of the laser oscillation modes using a polarization controller (PC). A split bright–dark pulse is generated when further increasing the pump power up to 37.95 mW. Stable bright pulses with no obvious evidence of a dark pulse can also be generated when further adjusting PC and increasing the pump power up to 52.19 mW. At higher pump power of 54.96 mW, a new form of bright-dark pulse emission was successfully identified with the repetition rate of 29 kHz. The bright and dark pulses have a duration of 795.5 ns and 640 ns, respectively. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Erbium-doped%20fiber%20laser" title="Erbium-doped fiber laser">Erbium-doped fiber laser</a>, <a href="https://publications.waset.org/abstracts/search?q=nonlinear%20polarization%20rotation" title=" nonlinear polarization rotation"> nonlinear polarization rotation</a>, <a href="https://publications.waset.org/abstracts/search?q=bright-dark%20pulse" title=" bright-dark pulse"> bright-dark pulse</a>, <a href="https://publications.waset.org/abstracts/search?q=photonic" title=" photonic"> photonic</a> </p> <a href="https://publications.waset.org/abstracts/19127/bright-dark-pulses-in-nonlinear-polarisation-rotation-based-erbium-doped-fiber-laser" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/19127.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">524</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">29</span> Unravelling Domestic Electricity Demand by Domestic Renewable Energy Supply: A Case Study in Yogyakarta and Central Java, Indonesia</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Diyono%20Harun">Diyono Harun</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Indonesia aims to reduce carbon emissions from energy generation by reaching 23% and 31% of the national energy supply from renewable energy sources (RES) in 2025 and 2030. The potential for RES in Indonesia is enormous, but not all province has the same potential for RES. Yogyakarta, one of the most travel-destinated provinces in Indonesia, has less potential than its neighbour, Central Java. Consequently, Yogyakarta must meet its electricity demand by importing electricity from Central Java if this province only wants to use electricity from RES. Thus, achieving the objective is balancing the electricity supply between an importer (Yogyakarta) and an exporter province (Central Java). This research aims to explore the RES potential and the current capacity of RES for electricity generation in both provinces. The results show that the present capacity of RES meets the annual domestic electricity demand in both provinces only with an extension of the RES potential. The renewable energy mixes in this research also can lower CO2 emissions compared to gas-fired power plants. This research eventually provides insights into exploring and using the domestic RES potentials between two areas with different RES capacities. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=energy%20mix" title="energy mix">energy mix</a>, <a href="https://publications.waset.org/abstracts/search?q=renewable%20energy%20sources" title=" renewable energy sources"> renewable energy sources</a>, <a href="https://publications.waset.org/abstracts/search?q=domestic%20electricity" title=" domestic electricity"> domestic electricity</a>, <a href="https://publications.waset.org/abstracts/search?q=electricity%20generation" title=" electricity generation"> electricity generation</a> </p> <a href="https://publications.waset.org/abstracts/162934/unravelling-domestic-electricity-demand-by-domestic-renewable-energy-supply-a-case-study-in-yogyakarta-and-central-java-indonesia" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/162934.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">88</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">28</span> Design and Characterization of CMOS Readout Circuit for ISFET and ISE Based Sensors</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Yuzman%20Yusoff">Yuzman Yusoff</a>, <a href="https://publications.waset.org/abstracts/search?q=Siti%20Noor%20Harun"> Siti Noor Harun</a>, <a href="https://publications.waset.org/abstracts/search?q=Noor%20Shelida%20Salleh"> Noor Shelida Salleh</a>, <a href="https://publications.waset.org/abstracts/search?q=Tan%20Kong%20Yew"> Tan Kong Yew</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper presents the design and characterization of analog readout interface circuits for ion sensitive field effect transistor (ISFET) and ion selective electrode (ISE) based sensor.

The nano-CaCO3 and nanoclay reinforced HDPE granules were prepared by the melt blending method using a compounder system, which consists of industrial banbury mixer, single screw extruder and granule cutting in industrial-scale. The nano-CaCO3 and nanoclay reinforced HDPE granules were molded using an injection-molding machine as plates, and then impact samples were cut by using punching die from the nanocomposite plates. As a result of impact experiments, nano-CaCO3 and nanoclay reinforced HDPE nanocomposites were determined to have lower impact energy level than neat HDPE. Also, the impact strength of HDPE further decreased by addition nanoclay compared to nano-CaCO3. The occurred fracture areas with the impact were detected by SEM examination. It is understood that fracture surface morphology changes when nano-CaCO3 and nanoclay ratio increases. The fracture surface changes were examined to determine the fracture mechanism of nano-CaCO3 and nanoclay reinforced HDPE nanocomposites. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=charpy" title="charpy">charpy</a>, <a href="https://publications.waset.org/abstracts/search?q=HDPE" title=" HDPE"> HDPE</a>, <a href="https://publications.waset.org/abstracts/search?q=industrial%20scale%20nano-CaCO3" title=" industrial scale nano-CaCO3"> industrial scale nano-CaCO3</a>, <a href="https://publications.waset.org/abstracts/search?q=nanoclay" title=" nanoclay"> nanoclay</a>, <a href="https://publications.waset.org/abstracts/search?q=nanocomposite" title=" nanocomposite"> nanocomposite</a> </p> <a href="https://publications.waset.org/abstracts/37073/comparative-study-of-impact-strength-and-fracture-morphological-of-nano-caco3-and-nanoclay-reinforced-hdpe-nanocomposites" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/37073.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">411</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">26</span> M-Machine Assembly Scheduling Problem to Minimize Total Tardiness with Non-Zero Setup Times</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Harun%20Aydilek">Harun Aydilek</a>, <a href="https://publications.waset.org/abstracts/search?q=Asiye%20Aydilek"> Asiye Aydilek</a>, <a href="https://publications.waset.org/abstracts/search?q=Ali%20Allahverdi"> Ali Allahverdi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Our objective is to minimize the total tardiness in an m-machine two-stage assembly flowshop scheduling problem.

This performance measure is particularly important in situations where there is a cost to complete a job beyond its due date. The cost of scheduling increases as the gap between a job's due date and its completion time increases. Such costs may also be penalty costs in contracts, loss of goodwill. This performance measure is important as the fulfillment of due dates of customers has to be taken into account while making scheduling decisions. The problem is addressed in the literature, however, it has been assumed zero setup times. Even though this assumption may be valid for some environments, it is not valid for some other scheduling environments. When setup times are treated as separate from processing times, it is possible to increase machine utilization and to reduce total tardiness. Therefore, non-zero setup times need to be considered as separate. A dominance relation is developed and several algorithms are proposed. The developed dominance relation is utilized in the proposed algorithms. Extensive computational experiments are conducted for the evaluation of the algorithms. The experiments indicated that the developed algorithms perform much better than the existing algorithms in the literature. More specifically, one of the newly proposed algorithms reduces the error of the best existing algorithm in the literature by 40 percent. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=algorithm" title="algorithm">algorithm</a>, <a href="https://publications.waset.org/abstracts/search?q=assembly%20flowshop" title=" assembly flowshop"> assembly flowshop</a>, <a href="https://publications.waset.org/abstracts/search?q=dominance%20relation" title=" dominance relation"> dominance relation</a>, <a href="https://publications.waset.org/abstracts/search?q=total%20tardiness" title=" total tardiness"> total tardiness</a> </p> <a href="https://publications.waset.org/abstracts/29889/algorithms-minimizing-total-tardiness" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/29889.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">354</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">24</span> Growth of Nitella in Response to Cesium Exposure: Implication for Phytoremediation</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Harun%20Rashid">Harun Rashid</a>, <a href="https://publications.waset.org/abstracts/search?q=Keerthi%20S.%20S.%20Atapaththu"> Keerthi S.

Each treatment with three replicates were randomly allocated to 12 glass beakers in a complete randomize design and the experiment was continued for 30 days. At the end of the experiment, shoot length, cesium content, total chlorophyll, and plant stress response were compared. Anti-oxidant enzyme activities (peroxidase, catalase, and ascorbic peroxidase) and the concentration of H2O2 were measured to check plant stress. The longest shoot was found in control treatment (0 ppm Cs) and the shoot length of plants exposed to 0.001 ppm was statistically similar to that of control. Concentration of cesium in plants grown at 0.001, 0.01, and 0.1 ppm were significantly higher than those in control treatments. The antioxidant enzymes activities of plants exposed to cesium were significantly higher than those grown without any Cs (control). An elevated level of H2O2 concentration was also observed in former groups of plants. Further, the reduction in chlorophyll concentration and chlorophyll fluorescence in response to cesium exposure indicated the chronically damaged photosynthetic efficiency in cesium stressed Nitella. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=antioxidant%20enzymes" title="antioxidant enzymes">antioxidant enzymes</a>, <a href="https://publications.waset.org/abstracts/search?q=cesium" title=" cesium"> cesium</a>, <a href="https://publications.waset.org/abstracts/search?q=growth" title=" growth"> growth</a>, <a href="https://publications.waset.org/abstracts/search?q=Nitella" title=" Nitella"> Nitella</a>, <a href="https://publications.waset.org/abstracts/search?q=oxidative%20stress" title=" oxidative stress"> oxidative stress</a> </p> <a href="https://publications.waset.org/abstracts/24580/growth-of-nitella-in-response-to-cesium-exposure-implication-for-phytoremediation" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/24580.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">425</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">23</span> Potential Micro Hydro at Irrigation Canal in the Gorontalo Province and Modeling Setling Basin for Reduction of Sedimentation Effect</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Arifin%20Matoka">Arifin Matoka</a>, <a href="https://publications.waset.org/abstracts/search?q=Nadjamuddin%20Harun"> Nadjamuddin Harun</a>, <a href="https://publications.waset.org/abstracts/search?q=Salama%20Manjang"> Salama Manjang</a>, <a href="https://publications.waset.org/abstracts/search?q=M.%20Arsyad%20Thaha"> M.

We find that suboptimal stock holdings impose only modest costs on the retiree. This may have a merit in explaining the limited stock investment in the data. The cost of suboptimal bond holdings is higher than that of stocks, but still small. This may partially explain why many more people hold bonds compared to stocks. We find that positive deviations from the optimal level are less costly relative to the negative ones in suboptimal housing allocations. This may help us to clarify why the elderly are over consuming housing, as seen in the housing data. The cost of suboptimal consumption is quite high and the highest of all. Our paper suggests that, in terms of welfare, the decisions of how much of liquid wealth to use for consumption and for saving are more important than the decision about the composition of liquid savings. Suboptimal stock holdings are twice more costly in power utility and suboptimal bond holdings are twenty times more costly in recursive utility. Recursive utility is superior to power utility in terms of rationalizing many people's preference for bonds instead of stocks in investment. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=housing" title="housing">housing</a>, <a href="https://publications.waset.org/abstracts/search?q=recursive%20utility" title=" recursive utility"> recursive utility</a>, <a href="https://publications.waset.org/abstracts/search?q=retirement" title=" retirement"> retirement</a>, <a href="https://publications.waset.org/abstracts/search?q=suboptimal%20decisions" title=" suboptimal decisions"> suboptimal decisions</a>, <a href="https://publications.waset.org/abstracts/search?q=welfare%20cost" title=" welfare cost"> welfare cost</a> </p> <a href="https://publications.waset.org/abstracts/29920/suboptimal-retiree-allocations-with-housing" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/29920.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">317</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">21</span> The 10-year Risk of Major Osteoporotic and Hip Fractures Among Indonesian People Living with HIV</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Iqbal%20Pramukti">Iqbal Pramukti</a>, <a href="https://publications.waset.org/abstracts/search?q=Mamat%20Lukman"> Mamat Lukman</a>, <a href="https://publications.waset.org/abstracts/search?q=Hasniatisari%20Harun"> Hasniatisari Harun</a>, <a href="https://publications.waset.org/abstracts/search?q=Kusman%20Ibrahim"> Kusman Ibrahim</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Introduction: People living with HIV had a higher risk of osteoporotic fracture than the general population. The purpose of this study was to predict the 10-year risk of fracture among people living with HIV (PLWH) using FRAX™ and to identify characteristics related to the fracture risk. Methodology: This study consisted of 75 subjects. The ten-year probability of major osteoporotic fractures (MOF) and hip fractures was assessed using the FRAX™ algorithm. A cross-tabulation was used to identify the participant’s characteristics related to fracture risk. Results: The overall mean 10-year probability of fracture was 2.4% (1.7) for MOF and 0.4% (0.3) for hip fractures. For MOF score, participants with parents’ hip fracture history, smoking behavior and glucocorticoid use showed a higher MOF score than those who were not (3.1 vs. 2.5; 4.6 vs 2.5; and 3.4 vs 2.5, respectively). For HF score, participants with parents’ hip fracture history, smoking behavior and glucocorticoid use also showed a higher HF score than those who were not (0.5 vs. 0.3; 0.8 vs. 0.3; and 0.5 vs. 0.3, respectively). Conclusions: The 10-year risk of fracture was higher among PLWH with several factors, including the parent’s hip. Fracture history, smoking behavior and glucocorticoid used. Further analysis on determining factors using multivariate regression analysis with a larger sample size is required to confirm the factors associated with the high fracture risk. <p
