In addition, they are dependent on energy from fossil resources, which are depleting rapidly and they are not being properly utilized due to the relatively low efficiency of heat engines usually expressed by Carnot's efficiency. The low temperature direct conversion process, in which hydrogen is chemically oxidized, is one of the best alternatives to heat engines. In this process, the heat emitted to the surroundings, or in driving the reaction, is kept to a minimum. This method would meet the pressing need of humanity to find power generation and utilization techniques that are more efficient and less harmful to the environment than conventional power generation methods. This will also help to conserve energy resources, and at the same time, protect the environment by reducing the amount of harmful emissions, and thermal loading i.e. greenhouse effects. In fact, the fuel cell technology can overcome these difficulties and pave the way for utilizing different sources of energy. This paper investigates the possibility of utilizing fuel cell technologies in Dubai public transportation and in particular the rail systems. This matter is critical for Dubai since it is one of the fastest growing cities. Recently Dubai has launched the Clean Energy Strategy, which aims to make Dubai a global centre of clean energy and green economy. The utilization of fuel cell technology is very important for Dubai since it has the potential to increase energy efficiency of the transportation sector, increase energy security, improve environmental quality, and position Dubai as a leading city in advanced rail transportation.","PeriodicalId":328866,"journal":{"name":"2018 Advances in Science and Engineering Technology International Conferences (ASET)","volume":"705 ","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-06-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133522944","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Noise is a very distracting phenomena and an environmental concern caused by various sources. Noise pollution is becoming more severe with the introduction of massive human activities and the use of heavy machineries, and hence, it has been investigated by many researchers to highlight its environmental impacts and to find methods for its attenuation. Worldwide research focus on noise measurement, comparison of the efficacy of different noise barriers, development of noise models, and proposing viable solutions for its attenuation. Many technologies have been utilized for noise mitigation including insulation, absorption, damping and isolation. In this research, to mitigate the airborne noise level, passive noise control methods are applied by changing boundary conditions and using different materials in the bottom of the cavities. The wind tunnel experiments and CFD modelling reveals that such passive noise control measures have significant effects on controlling the noise level. The investigation also includes CFD modeling for the impact of local velocity distribution in the cavity regions on the noise level.","PeriodicalId":328866,"journal":{"name":"2018 Advances in Science and Engineering Technology International Conferences (ASET)","volume":"153 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-06-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131123515","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This is due to two main reasons: Fossil fuels will continue to supply energy demands for only a few more decades and the amount of pollution generated due to fossil fuels is exceeding acceptable limits. One very promising clean energy converter is the fuel cell (FC). Fuel cells have the ability to convert the chemical energy of their feed fuel to electricity through a chemical process without involving combustion, which significantly reduces harmful emissions such as NOx. Fuel cells generate absolutely no harmful emissions when their fuel supply is pure hydrogen and they are more efficient than internal combustion engines. This research will investigate the feasibility of utilizing fuel cells in the public transportation system of Dubai operated by the Roads & Transportation Authority (RTA), in order to gradually replace transportation fleets running on fossil fuel engines to engines running on pure hydrogen. The Proton Exchange Membrane (PEM) fuel cell is one of the leading technologies which has started to replace internal combustion engines. However, technology development, cost, durability and lack of relevant infrastructures are the biggest challenges to the implementation of FC.","PeriodicalId":328866,"journal":{"name":"2018 Advances in Science and Engineering Technology International Conferences (ASET)","volume":"144 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-06-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127507803","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This work mainly focuses on onshore type of wind turbines and briefly mentioning the offshore wind turbines. The introduction gives an overview of the main parts and components of wind turbine, in addition to discussing the process of risk assessment and the procedure to be followed in this study. The paper focuses on the following four risks: the risk of transporting large-scale wind turbine parts and components, the risk of workers slipping, tripping and falling during installation and maintenance of wind turbines, the risk of working in confined spaces, and finally the risk of ice accretion and irregular shedding when the wind turbine is in operation phase or even when it is stationary. The last type of risk is highly observed in cold climate regions. The four mentioned types of risks are the main ones out of the many risks that could appear during transporting, installing, operating and maintaining wind turbines. The main aim of this work is to contribute in the proper risk assessment of potential hazards, which enhances the ability to devise passive and active protection measures to reduce the effects of a catastrophic event.","PeriodicalId":328866,"journal":{"name":"2018 Advances in Science and Engineering Technology International Conferences (ASET)","volume":"7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-06-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114961559","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The aim is to analyze, longitudinally, the changes of students' perception of the three psychological needs of the SDT (perceived autonomy support, competence, and relatedness to fellow learners) as well as the students' learning motivation, by comparing student perceptions after completing the first semester, with their perceptions after completing the third semester. Students' perceptions are measured using a 7-point Likert scale and descriptive and inferential statistics are applied, as is an analysis of correlations between the constructs of the framework. It is found that the learning motivation improved and students' perceived autonomy support increased significantly. Furthermore, correlations suggest that students derive their perceived competence more from learning facilitators as opposed to peers and that perceived competence has some positive impact on learning motivation. This study is part of an ongoing research effort related to novice project-based learners in the GCC region.","PeriodicalId":328866,"journal":{"name":"2018 Advances in Science and Engineering Technology International Conferences (ASET)","volume":"77 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-06-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133012472","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In biology, this allows for analysis of mammalian cells, neurons and tissue samples that are otherwise difficult to culture in conventional microfluidic devices. In this paper, we demonstrate how 3-D printing can be used to expedite the design-test cycle of the MFP and hence democratize the concept. The 3D printing procedures were adapted in fabricating the MFPs that were used for all experiments. Characterization of MFP's flow profile footprints are performed by comparisons with numerically calculated profiles. Application of the MFP is then used to selectively label adherent cells cultured in a Petri dish, within their conventional culture environment. Results show that while the 3D printed probes contain some artifacts, they function just as well as MFPs microfabricated using conventional techniques. Overall, this fabrication demonstrates a rapid, easy, and affordable fabrication technique for the MFP.","PeriodicalId":328866,"journal":{"name":"2018 Advances in Science and Engineering Technology International Conferences (ASET)","volume":"10 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-06-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129694249","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
