After chemical treatment and drying, SCB was pre-mixed with HDPE using twin extruder. The resulting granules are used in producing samples in injection molding machine. SCB with the quantity of %10, %20, and %30 was used. By using a suitable fixture, screw heads can take with tensile test machine grips. Parts with screws in the center and edge were fasten together. Then, withdrawal resistance was measured with tensile test machine. Injection gate is at the one edge of the part. The results show that by increasing SCB content in composite, the withdrawal resistance is decreased. Furthermore, the withdrawal resistance at the edges (near injection gate and the end of the filling path of mold cavity) is more than that of the center. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=polyethylene" title="polyethylene">polyethylene</a>, <a href="https://publications.waset.org/abstracts/search?q=sugarcane%20bagasse" title=" sugarcane bagasse"> sugarcane bagasse</a>, <a href="https://publications.waset.org/abstracts/search?q=wood%20plastic" title=" wood plastic"> wood plastic</a>, <a href="https://publications.waset.org/abstracts/search?q=screw" title=" screw"> screw</a>, <a href="https://publications.waset.org/abstracts/search?q=withdrawal%20resistance" title=" withdrawal resistance"> withdrawal resistance</a> </p> <a href="https://publications.waset.org/abstracts/32925/investigation-on-the-effect-of-sugarcane-bagassehdpe-composition-on-the-screw-withdrawal-resistance-of-injection-molded-parts" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/32925.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">583</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">274</span> Effect of Cuminum Cyminum L.

Humans and most domesticated animals harbor S. aureus, and so we may expect staphylococci to be present in food products of animal origin or in those handled directly by humans, unless heat processing is applied to destroy them. Cuminum cyminum L. has been allocated the topic of some recent studies in addition to its well-documented traditional usage for treatment of toothache, dyspepsia, diarrhea, epilepsy and jaundice. The air-dried seed of the plant was completely immersed in water and subjected to hydro distillation for 3 h, using a clevenger-type apparatus. In this study, the effect of Cuminum cyminum L. essential oil (EO) on growth of Staphylococcus aureus in white brined cheese was evaluated. The experiment included different levels of EO (0, 7.5, 15 and 30 mL/ 100 mL milk) to assess their effects on S. aureus count during the manufacture, ripening and storage of Iranian white brined cheese for up to 75 days. The significant (P < 0.05) inhibitory effects of EO (even at its lowest concentration) on this organism were observed. The significant (P < 0.05) inhibitory effect of the EO on S. aureus shown in this study may improve the scope of the EO function in the food industry. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=cuminum%20cyminum%20L.%20essential%20oil" title="cuminum cyminum L. essential oil">cuminum cyminum L. essential oil</a>, <a href="https://publications.waset.org/abstracts/search?q=staphylococcus%20aureus" title=" staphylococcus aureus"> staphylococcus aureus</a>, <a href="https://publications.waset.org/abstracts/search?q=white%20brined%20cheese" title=" white brined cheese"> white brined cheese</a> </p> <a href="https://publications.waset.org/abstracts/23074/effect-of-cuminum-cyminum-l-essential-oil-on-staphylococcus-aureus-during-the-manufacture-ripening-and-storage-of-white-brined-cheese" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/23074.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">273</span> Vectorial Capacity and Age Determination of Anopheles Maculipinnis S.

For evaluation of immunization, we determined the kinetics of the distribution of Toxoplasma and parasite load in different tissues of mice immunized by ESAs. Methods: In this experimental study, 36 mice in case (n= 18) and control (n= 18) groups were immunized with ESAs and PBS, respectively. After 2 weeks, mice were challenged intraperitoneally with Toxoplasma virulent RH strain. Blood and different tissues (brain, spleen, liver, heart, kidney, and muscle) were collected daily after challenge (1, 2, 3 and last day before death). Parasite load was calculated using Real time QPCR targeted at the B1 gene. Results: ESAs as vaccine in different tissues showed various effects. However, infected mice which received the vaccine in comparison with control group, displayed a drastically decreasing in parasite burden, in their blood and tissues (P= 0.000). Conclusion: These results indicated that ESAs with reduction of parasite load in different tissues of host could be evaluable candidate for the development of immunization strategies against toxoplasmosis. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=parasitic%20load" title="parasitic load">parasitic load</a>, <a href="https://publications.waset.org/abstracts/search?q=murine%20toxoplasmosis" title=" murine toxoplasmosis"> murine toxoplasmosis</a>, <a href="https://publications.waset.org/abstracts/search?q=immunization" title=" immunization"> immunization</a>, <a href="https://publications.waset.org/abstracts/search?q=excretory-secretory%20antigens" title=" excretory-secretory antigens"> excretory-secretory antigens</a>, <a href="https://publications.waset.org/abstracts/search?q=real%20time%20QPCR" title=" real time QPCR"> real time QPCR</a> </p> <a href="https://publications.waset.org/abstracts/15697/determination-of-parasitic-load-in-different-tissues-of-murine-toxoplasmosis-after-immunization-by-excretory-secretory-antigens-using-real-time-qpcr" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/15697.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">444</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">271</span> Quantitative Evaluation of Diabetic Foot Wound Healing Using Hydrogel Nanosilver Based Dressing vs. Traditional Dressing: A Prospective Randomized Control Study</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ehsan%20A.%20Yahia">Ehsan A.

It can be generated either directly by vibrating machineries induced mechanical force, indirectly by the excitation of structure or excitation by incident airborne noise. Therefore, limiting of the transmission of vibration energy throughout the offshore platform is the key to control the structure-borne noise. This is usually done by introducing damping treatment to the steel structures. Two types of damping treatment using on-board are presented. By conducting a statistical energy analysis (SEA) simulation on a jack-up rig, the noise level in the source room, the neighboring rooms, and remote living quarter cabins are compared before and after the damping treatments been applied. The results demonstrated that, in the source neighboring room and living quarter area, there is a significant noise reduction with the damping treatment applied, whereas in the source room where air-borne sound predominates that of structure-borne sound, the impact is not obvious. The subsequent optimization design of damping treatment in the offshore platform can be made which enable acoustic professionals to implement noise control during the design stage for offshore crews’ hearing protection and habitant comfortability. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=statistical%20energy%20analysis" title="statistical energy analysis">statistical energy analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=damping%20treatment" title=" damping treatment"> damping treatment</a>, <a href="https://publications.waset.org/abstracts/search?q=noise%20control" title=" noise control"> noise control</a>, <a href="https://publications.waset.org/abstracts/search?q=offshore%20platform" title=" offshore platform"> offshore platform</a> </p> <a href="https://publications.waset.org/abstracts/33178/the-effect-of-damping-treatment-for-noise-control-on-offshore-platforms-using-statistical-energy-analysis" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/33178.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">554</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">269</span> Experimental Investigation of Soil Corrosion and Electrical Resistance in Depth by Geoelectrical Method</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Seyed%20Abolhassan%20Naeini">Seyed Abolhassan Naeini</a>, <a href="https://publications.waset.org/abstracts/search?q=Maedeh%20Akhavan%20Tavakkoli"> Maedeh Akhavan Tavakkoli</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Determining soil engineering properties is essential for geotechnical problems. In addition to high cost, invasive soil survey methods can be time-consuming, so geophysical methods can be an excellent choice to determine soil characteristics. In this study, geoelectric investigation using the Wenner arrangement method has been used to determine the amount of soil corrosion in soil layers in a project site as a case study. This study aims to assess the degree of corrosion of soil layers to a depth of 5 meters and find the variation of soil electrical resistance versus depth. For this purpose, the desired points in the study area were marked and specified, and all withdrawals were made within the specified points. The collected data have been processed by standard and accepted methods, and the results have been presented in the form of calculation tables and curves of electrical resistivity with depth. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Wenner%20array" title="Wenner array">Wenner array</a>, <a href="https://publications.waset.org/abstracts/search?q=geoelectric" title=" geoelectric"> geoelectric</a>, <a href="https://publications.waset.org/abstracts/search?q=soil%20corrosion" title=" soil corrosion"> soil corrosion</a>, <a href="https://publications.waset.org/abstracts/search?q=electrical%20soil%20resistance" title=" electrical soil resistance"> electrical soil resistance</a> </p> <a href="https://publications.waset.org/abstracts/146292/experimental-investigation-of-soil-corrosion-and-electrical-resistance-in-depth-by-geoelectrical-method" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/146292.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">102</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">268</span> The Effect of Global Warming on Water Resources</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ehsan%20Soltanzadeh">Ehsan Soltanzadeh</a>, <a href="https://publications.waset.org/abstracts/search?q=Hassan%20Zare"> Hassan Zare</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper introduces examples of the influences of global warming on water resources and means of adaptation. The contributing causes of shortage in water resources are sophisticated and have interactions with each other. The world-scale phenomena like global warming have led to an increase in air and ocean’s mean temperature, and this has already caused adverse effects on water resources. Other factors that exacerbated this situation such as population increase, changes in farming habits, rise in city dwellers, unbalanced request for energy and aquatic resources, improved living standards, new eating habits, increasing economic growth and consequently flourishing industrial activities, and different types of pollution such as air, water, etc., are compelling more pressure on our limited water resources. The report will briefly discuss climate change and its detrimental impacts on the water resources and finally will introduce two effective solutions to mitigate the consequences or even reverse them in the near to mid-term future: utilization of molten salt technology for storing huge amounts of generated electricity in solar power plants to accommodate power grid demands, and implementing fuel cell CHPs to reduce carbon emission, and consequently, mitigate the global warming phenomenon as the major root cause of threatening water resources. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=climate%20change" title="climate change">climate change</a>, <a href="https://publications.waset.org/abstracts/search?q=global%20warming" title=" global warming"> global warming</a>, <a href="https://publications.waset.org/abstracts/search?q=water%20resources" title=" water resources"> water resources</a>, <a href="https://publications.waset.org/abstracts/search?q=GHG%20emissions" title=" GHG emissions"> GHG emissions</a>, <a href="https://publications.waset.org/abstracts/search?q=fuel%20cell-CHP" title=" fuel cell-CHP"> fuel cell-CHP</a>, <a href="https://publications.waset.org/abstracts/search?q=solar%20power%20plant" title=" solar power plant"> solar power plant</a>, <a href="https://publications.waset.org/abstracts/search?q=molten%20salt%20storage" title=" molten salt storage"> molten salt storage</a> </p> <a href="https://publications.waset.org/abstracts/151405/the-effect-of-global-warming-on-water-resources" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/151405.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">112</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">267</span> Evaluation of Numerical Modeling of Jet Grouting Design Using in situ Loading Test</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Reza%20Ziaie%20Moayed">Reza Ziaie Moayed</a>, <a href="https://publications.waset.org/abstracts/search?q=Ehsan%20Azini"> Ehsan Azini</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Jet grouting (JG) is one of the methods of improving and increasing the strength and bearing of soil in which the high pressure water or grout is injected through the nozzles into the soil. During this process, a part of the soil and grout particles comes out of the drill borehole, and the other part is mixed up with the grout in place, as a result of this process, a mass of modified soil is created. The purpose of this method is to change the soil into a mixture of soil and cement, commonly known as "soil-cement". In this paper, first, the principles of high pressure injection and then the effective parameters in the JG method are described<span dir="RTL">.</span> Then, the tests on the samples taken from the columns formed from the excavation around the soil-cement columns, as well as the static loading test on the created column, are discussed. In the other part of this paper, the soil behavior models for numerical modeling in PLAXIS software are mentioned. The purpose of this paper is to evaluate the results of numerical modeling based on in-situ static loading tests. The results indicate an acceptable agreement between the results of the tests mentioned and the modeling results. Also, modeling with this software as an appropriate option for technical feasibility can be used to soil improvement using JG. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=jet%20grouting%20column" title="jet grouting column">jet grouting column</a>, <a href="https://publications.waset.org/abstracts/search?q=soil%20improvement" title=" soil improvement"> soil improvement</a>, <a href="https://publications.waset.org/abstracts/search?q=numerical%20modeling" title=" numerical modeling"> numerical modeling</a>, <a href="https://publications.waset.org/abstracts/search?q=in-situ%20loading%20test" title=" in-situ loading test"> in-situ loading test</a> </p> <a href="https://publications.waset.org/abstracts/111026/evaluation-of-numerical-modeling-of-jet-grouting-design-using-in-situ-loading-test" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/111026.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">143</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">266</span> Energy Saving Potential with Improved Concrete in Ice Rink Floor Designs </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ehsan%20B.%20Haghighi">Ehsan B.

The important part of the floor consists of concrete, and the thermophysical properties of this concrete have strong influence on the energy usage of the ice rink. The thermal conductivity of concrete can be increased by using iron ore as ballast. In this study the Transient Plane Source (TPS) method showed an increase up to 58.2% of thermal conductivity comparing the improved concrete to standard concrete. Moreover, two alternative ice rink floor designs are suggested to incorporate the improved concrete. A 2D simulation was developed to investigate the temperature distribution in the conventional and the suggested designs. The results show that the suggested designs reduce the temperature difference between the ice surface and the brine by 1-4 ˚C, when comparing with convectional designs at equal heat flux. This primarily leads to an increased coefficient of performance (COP) in the primary refrigeration cycle and secondly to a decrease in the secondary refrigerant pumping power. The suggested designs have great potential to reduce the energy usage of ice rinks. Depending on the load scenario in the ice rink, the saving potential lies in the range of 3-10% of the refrigeration system energy usage. This calculation is based on steady state conditions and the potential with improved dynamic behavior is expected to increase the potential saving. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Concrete" title="Concrete">Concrete</a>, <a href="https://publications.waset.org/abstracts/search?q=iron%20ore" title=" iron ore"> iron ore</a>, <a href="https://publications.waset.org/abstracts/search?q=ice%20rink" title=" ice rink"> ice rink</a>, <a href="https://publications.waset.org/abstracts/search?q=energy%20saving" title=" energy saving"> energy saving</a> </p> <a href="https://publications.waset.org/abstracts/5624/energy-saving-potential-with-improved-concrete-in-ice-rink-floor-designs" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/5624.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">342</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">265</span> Formulating the Stochastic Finite Elements for Free Vibration Analysis of Plates with Variable Elastic Modulus</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mojtaba%20Aghamiri%20Esfahani">Mojtaba Aghamiri Esfahani</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohammad%20Karkon"> Mohammad Karkon</a>, <a href="https://publications.waset.org/abstracts/search?q=Seyed%20Majid%20Hosseini%20Nezhad"> Seyed Majid Hosseini Nezhad</a>, <a href="https://publications.waset.org/abstracts/search?q=Reza%20Hosseini-Ara"> Reza Hosseini-Ara </a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this study, the effect of uncertainty in elastic modulus of a plate on free vibration response is investigated.

One of the most commonly used methods for constructing underground structures in urban areas is NATM (New Austrian tunneling method). In this method, there are some key parameters such as excavation steps and cross-sectional area that have a significant effect on the surface settlement. Settlement is a very important control factor related to safe excavation. In this paper, Finite Element Method is used by Abaqus. R6 station of Tehran Metro Line 6 is built by NATM and the construction of that is studied and analyzed. Considering the outcomes obtained from numerical modeling and comparison with the results of the instrumentation and monitoring of field, finally, the excavation step of 1 meter and longitudinal distance of 14 meters between side drifts is suggested to achieve safe tunneling with allowable settlement. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=excavation%20step" title="excavation step">excavation step</a>, <a href="https://publications.waset.org/abstracts/search?q=NATM" title=" NATM"> NATM</a>, <a href="https://publications.waset.org/abstracts/search?q=numerical%20modeling" title=" numerical modeling"> numerical modeling</a>, <a href="https://publications.waset.org/abstracts/search?q=settlement." title=" settlement."> settlement.</a> </p> <a href="https://publications.waset.org/abstracts/145297/investigation-of-the-effect-of-excavation-step-in-natm-on-surface-settlement-by-finite-element-method" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/145297.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">139</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">262</span> A Study on How to Improve PMBOK (Project Management Body of Knowledge) Guidelines Performance by Simulation</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Fatemeh%20Jaferi">Fatemeh Jaferi</a>, <a href="https://publications.waset.org/abstracts/search?q=Moslem%20Parsa"> Moslem Parsa</a>, <a href="https://publications.waset.org/abstracts/search?q=Seyed%20Mehdi%20Sajadi"> Seyed Mehdi Sajadi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The project-oriented organizations are more appropriate for sustainable environments. Any effective project-oriented organization should institutionalize its project management processes in such a manner to yield the greatest possible profits. The aim of this paper is to study the relationship between the project management PMBOK guideline (Project Management Body of Knowledge) and simulation technology in project-oriented organizations. The methodology involves using five steps for applying these two tools aimed at enhancing project management processes in the Lorestan Gas Corporation, as one of the project-oriented organization. Results show the implementation of such management approach leads to a 5% performance improvement and using PMBOK can be instrumental in effective delay management.

The dual fuel engine concept with premixed lean methane combustion ignited through diesel pilot flames reveals high potential for the abatement of the NOx formation. The drawback of this combustion method, however, is the high NO2 formation due to the increasing concentration of unburned hydrocarbons. This promotes the conversion of NO to NO2, which is toxic and characterized through its yellow color. The results presented in this paper cover a wide range of engine operation points from full load to part load for different air to fuel ratios. The effects of temperature, pressure and concentrations of unburned methane and nitric oxide on NO2 formation in the exhaust duct has been investigated on the basis of a zero-dimensional well stirred reactor model implemented in Cantera, which calculates the steady state of a uniform composition for a certain residence time. It can be shown that the simulated conversion of NO to NO2 match the experimental results fairly well. The partial oxidation of methane followed by CO production can be predicted as well. It can also be concluded that the lower temperature limit for which no conversion takes place, depends mainly on the concentration of the unburned hydrocarbons in the exhaust. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=cantera" title="cantera">cantera</a>, <a href="https://publications.waset.org/abstracts/search?q=dual%20fuel%20engines" title=" dual fuel engines"> dual fuel engines</a>, <a href="https://publications.waset.org/abstracts/search?q=exhaust%20tract" title=" exhaust tract"> exhaust tract</a>, <a href="https://publications.waset.org/abstracts/search?q=numerical%20modeling%20of%20NO2%20formation" title=" numerical modeling of NO2 formation"> numerical modeling of NO2 formation</a>, <a href="https://publications.waset.org/abstracts/search?q=well%20stirred%20reactor" title=" well stirred reactor"> well stirred reactor</a> </p> <a href="https://publications.waset.org/abstracts/81509/investigation-of-the-no2-formation-in-the-exhaust-duct-of-a-dual-fuel-test-engine" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/81509.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">219</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">260</span> Optimum Locations for Intercity Bus Terminals with the AHP Approach: Case Study of the City of Esfahan</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mehrdad%20Arabi">Mehrdad Arabi</a>, <a href="https://publications.waset.org/abstracts/search?q=Ehsan%20Beheshtitabar"> Ehsan Beheshtitabar</a>, <a href="https://publications.waset.org/abstracts/search?q=Bahador%20Ghadirifaraz"> Bahador Ghadirifaraz</a>, <a href="https://publications.waset.org/abstracts/search?q=Behrooz%20Forjanizadeh"> Behrooz Forjanizadeh</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Interaction between human, location and activity defines space.

From an engineering view it is fundamental that choosing a proper location for a specific civil activity requires evaluation of locations from different perspectives. The debate of desirable establishment of municipal service elements in urban regions is one of the most important issues related to urban planning. In this paper, the research type is applicable based on goal, and is descriptive and analytical based on nature. Initially existing terminals in Esfahan are surveyed and then new locations are presented based on evaluated criteria. In order to evaluate terminals based on the considered factors, an AHP model is used at first to estimate weight of different factors and then existing and suggested locations are evaluated using Arc GIS software and AHP model results. The results show that existing bus terminals are located in fairly proper locations.

The application of these kinds of network includes monitoring of pollutants (chemical, biological, and nuclear), oil fields detection, prediction of the likelihood of a tsunami in coastal areas, the use of wireless sensor nodes to monitor the passing submarines, and determination of appropriate locations for anchoring ships. This paper proposes a boundary coverage algorithm for intrusion detection in underwater sensor networks. In the first phase of the proposed algorithm, optimal deployment of nodes is done in the water. In the second phase, after the employment of nodes at the proper depth, clustering is executed to reduce the exchanges of messages between the sensors. In the third phase, the algorithm of "divide and conquer" is used to save energy and increase network efficiency. The simulation results demonstrate the efficiency of the proposed algorithm. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=boundary%20coverage" title="boundary coverage">boundary coverage</a>, <a href="https://publications.waset.org/abstracts/search?q=clustering" title=" clustering"> clustering</a>, <a href="https://publications.waset.org/abstracts/search?q=divide%20and%20%E2%80%8Econquer" title=" divide and ‎conquer"> divide and ‎conquer</a>, <a href="https://publications.waset.org/abstracts/search?q=underwater%20sensor%20nodes" title=" underwater sensor nodes"> underwater sensor nodes</a> </p> <a href="https://publications.waset.org/abstracts/58628/proposing-a-boundary-coverage-algorithm-for-underwater-sensor-network" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/58628.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">341</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">257</span> Effects of Transcranial Direct Current Stimulation on Post-Stroke Dysphagia</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ehsan%20Kaviani">Ehsan Kaviani</a>, <a href="https://publications.waset.org/abstracts/search?q=Azin%20Golmoradizade"> Azin Golmoradizade</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Introduction: Traditionally, tendons are considered to only contain tenocytes that are responsible for the maintenance, repair, and remodeling of tendons. Stem cells, which are termed tendon-derived stem cells, so this study we investigate the effect of transcranial direct current stimulation combined with swallowing training on post-stroke dysphagia. Methods: This review article is about effects of transcranial direct current stimulation (tDCS) on post-stroke dysphagia that were extracted from Science Direct, Pro quest, and Pub med Data Bases. 15 articles had been selected according to inclusion criteria from 2014 to 2019, and 6 of them had been deleted by exclusion criteria. Results: The results of our systematic review suggest that tDCS may represent a promising novel treatment for post-stroke dysphagia. However, to date, little is known about the optimal parameters of tDCS for relieving post-stroke dysphagia. Further studies are warranted to refine this promising intervention by exploring the optimal parameters of tDCS. Conclusion: anodal tDCS over the affected hemisphere may be as effective as cathodal tDCS on the unaffected hemisphere to enhance recovery after subacute ischemic stroke and anodal tdcs applied over the affected pharyngeal motor cortex can enhance the outcome of swallowing training in post-stroke dysphagia. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=dysphagia" title="dysphagia">dysphagia</a>, <a href="https://publications.waset.org/abstracts/search?q=stroke" title=" stroke"> stroke</a>, <a href="https://publications.waset.org/abstracts/search?q=cortical%20stimulation" title=" cortical stimulation"> cortical stimulation</a>, <a href="https://publications.waset.org/abstracts/search?q=transcranial%20direct%20current%20stimulation" title=" transcranial direct current stimulation"> transcranial direct current stimulation</a> </p> <a href="https://publications.waset.org/abstracts/126193/effects-of-transcranial-direct-current-stimulation-on-post-stroke-dysphagia" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/126193.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">135</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">256</span> Numerical Investigation of Wastewater ‎Rheological Characteristics on Flow Field ‎Inside a Sewage Network</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Seyed-Mohammad-Kazem%20Emami">Seyed-Mohammad-Kazem Emami</a>, <a href="https://publications.waset.org/abstracts/search?q=Behrang%20Saki"> Behrang Saki</a>, <a href="https://publications.waset.org/abstracts/search?q=Majid%20Mohammadian"> Majid Mohammadian</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The wastewater flow field inside a sewage network including pipe and ‎manhole was investigated using a Computational Fluid Dynamics ‎‎(CFD) model.

Especially, the stain removal is significantly important in the Far East market, where the high percentage of the consumers use the top load washing machines as washing appliance. They use all pretreatment methods (i.e. soaking, prewash, and heavy functions) to eliminate the stains from their clothes. Therefore, with this study it is aimed to study experimentally the stain removal performance of 3 different Top-Loading washing machines of the Far East market with 24 different types of stains which are mostly related to Far East culture. In the meanwhile, the mechanical damge on laundry is examined for each machine to see the mechanical effect of the related stain programs on the textile load of the machines. The test machines vary according to have a heater, moving part(s)on their impeller, and to be in different height/width ratio of the drum. The results indicate that decreasing the water level inside the washing machine might result in better soil removal as well as less textile damage. Beside this, the experimental results reveal that heating has the main effect on stain removal. Two-step (or delayed) heating and a lower amount of water can also be considered as the further parameters <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=laundry" title="laundry">laundry</a>, <a href="https://publications.waset.org/abstracts/search?q=washing%20machine" title=" washing machine"> washing machine</a>, <a href="https://publications.waset.org/abstracts/search?q=top%20load%20washing%20machine" title=" top load washing machine"> top load washing machine</a>, <a href="https://publications.waset.org/abstracts/search?q=stain%20removal" title=" stain removal"> stain removal</a>, <a href="https://publications.waset.org/abstracts/search?q=textile%20damage" title=" textile damage"> textile damage</a>, <a href="https://publications.waset.org/abstracts/search?q=mechanical%20textile%20damage" title=" mechanical textile damage"> mechanical textile damage</a> </p> <a href="https://publications.waset.org/abstracts/152389/experimental-investigation-of-stain-removal-performance-of-different-types-of-top-load-washing-machines-with-textile-mechanical-damage-consideration" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/152389.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">124</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">254</span> Hybrid Diagrid System for High-Rise Buildings</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Seyed%20Saeid%20Tabaee">Seyed Saeid Tabaee</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohammad%20Afshari"> Mohammad Afshari</a>, <a href="https://publications.waset.org/abstracts/search?q=Bahador%20Ziaeemehr"> Bahador Ziaeemehr</a>, <a href="https://publications.waset.org/abstracts/search?q=Omid%20Bahar"> Omid Bahar</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Nowadays, using modern structural systems with specific capabilities, like Diagrid, is emerging around the world.

The scaled specimen of the suggested hybrid system was built and tested using IIEES shaking table. The natural frequency and structural response of the analytical model were updated with the real experimental results.

Alumina-cBN composites containing 10, 20 and 30wt% cBN with and without Ni coated were sintering at an elevated temperature of 1400°C at a constant uniaxial pressure of 50 MPa. The effect of matrix particle size, cBN and Ni content on mechanical properties and thermal properties, i.e., thermal conductivity, diffusivity, expansion, densification, phase transformation, microstructure, hardness and toughness of the Al2O3-cBN/(Ni) composites under specific sintering conditions were investigated. The highest relative densification of 150 nm-Al2O3 containing 30wt% cBN (Ni coated) composite was 99% at TSPS = 1400°C. In case of 150 µm- Al2O3 compositions, the phase transformation of cBN to hBN were observed, and the relative densification decreased. Thermal conductivity depicts maximum value in case of 150 nm- Al2O3-30wt% cBN-Ni composition.

In this analysis wings aerodynamic coefficient was calculated in different rake angle and wing lift curve slope to rake angle was achieved. Wing section was selected among NACA airfoils version 6. The sweep angle of wing is 15 degree, aspect ratio 8 and taper ratios 0.4. Designing and modeling this wing was done in CATIA software. This model was meshed in Gambit software and its three dimensional analysis was done in Fluent software. CFD methods used here were based on pressure base algorithm. SIMPLE technique was used for solving Navier-Stokes equation and Spalart-Allmaras model was utilized to simulate three dimensional wing in air. Roskam method is one of the common and most used methods for determining aerodynamics parameters in the field of airplane designing. In this study besides CFD analysis, an advanced aircraft analysis was used for calculating aerodynamic coefficient using Roskam method. The results of CFD were compared with measured data acquired from Roskam method and authenticity of relation was evaluated. The results and comparison showed that in linear region of lift curve there is a minor difference between aerodynamics parameter acquired from CFD to relation present by Roskam. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=aft%20sweep%20wing" title="aft sweep wing">aft sweep wing</a>, <a href="https://publications.waset.org/abstracts/search?q=CFD%20method" title=" CFD method"> CFD method</a>, <a href="https://publications.waset.org/abstracts/search?q=fluent" title=" fluent"> fluent</a>, <a href="https://publications.waset.org/abstracts/search?q=Roskam" title=" Roskam"> Roskam</a>, <a href="https://publications.waset.org/abstracts/search?q=Spalart-Allmaras%20model" title=" Spalart-Allmaras model"> Spalart-Allmaras model</a> </p> <a href="https://publications.waset.org/abstracts/33671/cfd-analysis-of-an-aft-sweep-wing-in-subsonic-flow-and-making-analogy-with-roskam-methods" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/33671.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">504</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">250</span> Effect of Deep Mixing Columns and Geogrid on Embankment Settlement on the Soft Soil</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Seyed%20Abolhasan%20Naeini">Seyed Abolhasan Naeini</a>, <a href="https://publications.waset.org/abstracts/search?q=Saeideh%20Mohammadi"> Saeideh Mohammadi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Embankment settlement on soft clays has always been problematic due to the high compaction and low shear strength of the soil.

For this purpose, the finite element method is used in the Plaxis 2D software. The Soft Soil Creep model considers the creep phenomenon in the soft clay layer while the Mohr-Columb model simulates other soil layers.

Interestingly, the fuels have a large effect on the size and morphology of nano-phosphors as well as luminescence properties. Noteworthy the use of isobutyl nitrite provides an average particle size of 65 nm, while the employment of urea, results in the formation of larger particles and also provides higher photoluminescence emission intensity.

Results indicated that learners in explicit focus on form group appear to benefit from error correction and rule explanation as two pedagogical techniques of explicit focus on form with respect to accuracy, but regarding fluency they did not yield any significant differences compared to the participants of meaning-focused group. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=explicit%20focus%20on%20form" title="explicit focus on form">explicit focus on form</a>, <a href="https://publications.waset.org/abstracts/search?q=rule%20explanation" title=" rule explanation"> rule explanation</a>, <a href="https://publications.waset.org/abstracts/search?q=accuracy" title=" accuracy"> accuracy</a>, <a href="https://publications.waset.org/abstracts/search?q=fluency" title=" fluency"> fluency</a> </p> <a href="https://publications.waset.org/abstracts/27326/the-effect-of-explicit-focus-on-form-on-second-language-learning-writing-performance" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/27326.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">510</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">247</span> Composite Distributed Generation and Transmission Expansion Planning Considering Security </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Amir%20Lotfi">Amir Lotfi</a>, <a href="https://publications.waset.org/abstracts/search?q=Seyed%20Hamid%20Hosseini"> Seyed Hamid Hosseini </a> </p> <p class="card-text"><strong>Abstract:</strong></p> During the recent past, due to the increase of electrical energy demand and governmental resources constraints in creating additional capacity in the generation, transmission, and distribution, privatization, and restructuring in electrical industry have been considered. So, in most of the countries, different parts of electrical industry like generation, transmission, and distribution have been separated in order to create competition. Considering these changes, environmental issues, energy growth, investment of private equity in energy generation units and difficulties of transmission lines expansion, distributed generation (DG) units have been used in power systems. Moreover, reduction in the need for transmission and distribution, the increase of reliability, improvement of power quality, and reduction of power loss have caused DG to be placed in power systems. On the other hand, considering low liquidity need, private investors tend to spend their money for DGs. In this project, the main goal is to offer an algorithm for planning and placing DGs in order to reduce the need for transmission and distribution network. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=planning" title="planning">planning</a>, <a href="https://publications.waset.org/abstracts/search?q=transmission" title=" transmission"> transmission</a>, <a href="https://publications.waset.org/abstracts/search?q=distributed%20generation" title=" distributed generation"> distributed generation</a>, <a href="https://publications.waset.org/abstracts/search?q=power%20security" title=" power security"> power security</a>, <a href="https://publications.waset.org/abstracts/search?q=power%20systems" title=" power systems"> power systems</a> </p> <a href="https://publications.waset.org/abstracts/68494/composite-distributed-generation-and-transmission-expansion-planning-considering-security" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/68494.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">480</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">246</span> Numerical Analysis of a Pilot Solar Chimney Power Plant</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ehsan%20Gholamalizadeh">Ehsan Gholamalizadeh</a>, <a href="https://publications.waset.org/abstracts/search?q=Jae%20Dong%20Chung"> Jae Dong Chung</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Solar chimney power plant is a feasible solar thermal system which produces electricity from the Sun. The objective of this study is to investigate buoyancy-driven flow and heat transfer through a built pilot solar chimney system called 'Kerman Project'. The system has a chimney with the height and diameter of 60 m and 3 m, respectively, and the average radius of its solar collector is about 20 m, and also its average collector height is about 2 m. A three-dimensional simulation was conducted to analyze the system, using computational fluid dynamics (CFD). In this model, radiative transfer equation was solved using the discrete ordinates (DO) radiation model taking into account a non-gray radiation behavior. In order to modelling solar irradiation from the sun’s rays, the solar ray tracing algorithm was coupled to the computation via a source term in the energy equation. The model was validated with comparing to the experimental data of the Manzanares prototype and also the performance of the built pilot system. Then, based on the numerical simulations, velocity and temperature distributions through the system, the temperature profile of the ground surface and the system performance were presented. The analysis accurately shows the flow and heat transfer characteristics through the pilot system and predicts its performance. <p class="card-text"><strong>Keywords:</strong> <a
