The temperature distribution is investigated using a co-flow planar SOFC comprising the air and fuel channel and two-ceramic electrodes, anode and cathode, separated by a dense ceramic electrolyte. The Lattice Boltzmann method (LBM) is used for the numerical simulation of the physical problem. The effects of inlet temperature, anode thermal conductivity and current density on temperature distribution are discussed. It was found that temperature distribution is very sensitive to the inlet temperature and the current density. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=heat%20sources" title="heat sources">heat sources</a>, <a href="https://publications.waset.org/abstracts/search?q=Lattice%20Boltzmann%20method" title=" Lattice Boltzmann method"> Lattice Boltzmann method</a>, <a href="https://publications.waset.org/abstracts/search?q=solid%20oxide%20fuel%20cell" title=" solid oxide fuel cell"> solid oxide fuel cell</a>, <a href="https://publications.waset.org/abstracts/search?q=temperature" title=" temperature"> temperature</a> </p> <a href="https://publications.waset.org/abstracts/71281/parametric-analysis-of-solid-oxide-fuel-cell-using-lattice-boltzmann-method" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/71281.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">309</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">111</span> Association Rules Mining Task Using Metaheuristics: Review</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Abir%20Derouiche">Abir Derouiche</a>, <a href="https://publications.waset.org/abstracts/search?q=Abdesslem%20Layeb"> Abdesslem Layeb </a> </p> <p class="card-text"><strong>Abstract:</strong></p> Association Rule Mining (ARM) is one of the most popular data mining tasks and it is widely used in various areas.

It has been regarded as a main driver for economic growth, development and employment generation in many countries worldwide. However, scholars have not agreed on the key factors that impact entrepreneurial intention. This study attempts, through an extensive literature review, to provide a holistic view and a more comprehensive understanding of the key factors that lead university undergraduate students to become entrepreneurs. A systematic literature review is conducted and several scientific articles and reports have been examined. The results of this study indicate that there are four main sets of factors: the personality-traits factors, contextual factors, motivational factors, and personal background factors. This research will serve as a base for future studies and will have valuable implications for policy makers and educators. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=entrepreneurship" title="entrepreneurship">entrepreneurship</a>, <a href="https://publications.waset.org/abstracts/search?q=entrepreneurial%20intention" title=" entrepreneurial intention"> entrepreneurial intention</a>, <a href="https://publications.waset.org/abstracts/search?q=literature%20review" title=" literature review"> literature review</a>, <a href="https://publications.waset.org/abstracts/search?q=economic%20growth" title=" economic growth"> economic growth</a> </p> <a href="https://publications.waset.org/abstracts/12564/factors-impacting-entrepreneurial-intention-a-literature-review" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/12564.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">299</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">104</span> Graft Copolymerization of Cellulose Acetate with Nitro-N-Amino Phenyl Maleimides</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Azza.%20A.%20Al-Ghamdi">Azza.

CA-g-2,4-dinitro amino phenyl maleimide exhibited higher thermal stability than the CA-g-4-nitro amino phenyl maleimide as shown from the initial decomposition temperature (T<sub>o</sub>). This is due to the ability of nitro group to form hydrogen bonding with hydroxyl group of the glucopyranose ring which increases the crystallinity of polymeric matrix. The crystalline shapes representing the graft part are clearly distinct in the Emission scanning electron microscope (ESEM) morphology of the copolymer. A suggested reaction mechanism for the grafting process was also discussed. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Cellulose%20acetate" title="Cellulose acetate">Cellulose acetate</a>, <a href="https://publications.waset.org/abstracts/search?q=Crystallinity" title=" Crystallinity"> Crystallinity</a>, <a href="https://publications.waset.org/abstracts/search?q=Graft%20copolymerization" title=" Graft copolymerization"> Graft copolymerization</a>, <a href="https://publications.waset.org/abstracts/search?q=Thermal%20properties" title=" Thermal properties"> Thermal properties</a> </p> <a href="https://publications.waset.org/abstracts/88277/graft-copolymerization-of-cellulose-acetate-with-nitro-n-amino-phenyl-maleimides" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/88277.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">162</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">103</span> Performance of an Absorption Refrigerator Using a Solar Thermal Collector</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Abir%20Hmida">Abir Hmida</a>, <a href="https://publications.waset.org/abstracts/search?q=Nihel%20Chekir"> Nihel Chekir</a>, <a href="https://publications.waset.org/abstracts/search?q=Ammar%20Ben%20Brahim"> Ammar Ben Brahim</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In the present paper, we investigate the feasibility of a thermal solar driven cold room in Gabes, southern region of Tunisia. The cold room of 109 m<sup>3</sup> is refrigerated using an ammonia absorption machine. It is destined to preserve dates during the hot months of the year. A detailed study of the cold room leads previously to the estimation of the cooling load of the proposed storage room in the operating conditions of the region. The next step consists of the estimation of the required heat in the generator of the absorption machine to ensure the desired cold temperature. A thermodynamic analysis was accomplished and complete description of the system is determined. We propose, here, to provide the needed heat thermally from the sun by using vacuum tube collectors. We found that at least 21m² of solar collectors are necessary to accomplish the work of the solar cold room. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=absorption" title="absorption">absorption</a>, <a href="https://publications.waset.org/abstracts/search?q=ammonia" title=" ammonia"> ammonia</a>, <a href="https://publications.waset.org/abstracts/search?q=cold%20room" title=" cold room"> cold room</a>, <a href="https://publications.waset.org/abstracts/search?q=solar%20collector" title=" solar collector"> solar collector</a>, <a href="https://publications.waset.org/abstracts/search?q=vacuum%20tube" title=" vacuum tube"> vacuum tube</a> </p> <a href="https://publications.waset.org/abstracts/99221/performance-of-an-absorption-refrigerator-using-a-solar-thermal-collector" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/99221.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">176</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">102</span> Analytical Formulae for Parameters Involved in Side Slopes of Embankments Stability</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Abdulrahman%20Abdulrahman">Abdulrahman Abdulrahman</a>, <a href="https://publications.waset.org/abstracts/search?q=Abir%20Abdulrahman"> Abir Abdulrahman</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The stability of slopes of earthen embankments is usually examined by Swedish slip circle method or the slices method. The factor of safety against sliding using Fellenius procedure depends upon the angle formed by the arc of sliding at the center ψ and the radius of the slip circle r. The values of both mentioned parameters ψ and r aren't precisely predicted because they are measured from the drawing. In this paper, analytical formulae were derived for finding the exact values of both ψ and r.

The main goal of this research is to explore the college students’ motives for using SNSs in education. A conceptual framework has therefore been developed to identify the main factors that influence/motivate students to use social networking sites for learning purposes. To achieve the research objectives a quantitative method was used to collect data. A questionnaire has been distributed amongst college students. The results reveal that social influence, perceived enjoyment, institute regulation, perceived usefulness, ranking up-lift, attractiveness, communication tools, free of charge, sharing material and course nature all play an important role in the motivation of college students to use SNSs for learning purposes. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Social%20Networking%20Sites%20%28SNSs%29" title="Social Networking Sites (SNSs)">Social Networking Sites (SNSs)</a>, <a href="https://publications.waset.org/abstracts/search?q=education" title=" education"> education</a>, <a href="https://publications.waset.org/abstracts/search?q=college%20students" title=" college students"> college students</a>, <a href="https://publications.waset.org/abstracts/search?q=motivations" title=" motivations"> motivations</a> </p> <a href="https://publications.waset.org/abstracts/12537/motivations-for-using-social-networking-sites-by-college-students-for-educational-purposes" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/12537.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">263</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">100</span> Comparison Constructions in the Language of the Qur'an</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Safiah%20Ahmed%20Yahya%20Madkhali">Safiah Ahmed Yahya Madkhali</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The aim of the present paper is to provide a characterization of the expression of comparison in the language of the Qur’an, the language of the Divine Book of the Muslim nation. It focuses on quantitative as well as qualitative comparisons. While works on comparison constructions in Arabic focus on a type(s) of the comparison construction and exclude another and investigate its behaviour in Standard Arabic, the paper aims to be inclusive of the varied instances that are scalar comparison constructions and describe its aspects in the language of the Qur’an. To the best of my knowledge, comparative constructions in the language of the Qur’an has not been tackled before and hence the characterization provided in the paper would be the contribution of the present work. The paper highlights the several rhetorical features of the construction as present in the different verses in the Qur’an which set them distinct from the ordinary use of the construction in the different verities of the Arabic language. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=comparison%20constructions" title="comparison constructions">comparison constructions</a>, <a href="https://publications.waset.org/abstracts/search?q=inequality" title=" inequality"> inequality</a>, <a href="https://publications.waset.org/abstracts/search?q=comparative" title=" comparative"> comparative</a>, <a href="https://publications.waset.org/abstracts/search?q=superlative" title=" superlative"> superlative</a>, <a href="https://publications.waset.org/abstracts/search?q=equality" title=" equality"> equality</a> </p> <a href="https://publications.waset.org/abstracts/150721/comparison-constructions-in-the-language-of-the-quran" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/150721.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">75</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">99</span> Morphometric Relationships of Length-Weight and Length-Length of Oreochromis aureus in Relation to Body Size and Condition Factor from Pakistan</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Muhammad%20Naeem">Muhammad Naeem</a>, <a href="https://publications.waset.org/abstracts/search?q=Abdus%20Salam"> Abdus Salam</a>, <a href="https://publications.waset.org/abstracts/search?q=Sumera%20Yasmin"> Sumera Yasmin</a>, <a href="https://publications.waset.org/abstracts/search?q=Abir%20Ishtiaq"> Abir Ishtiaq</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In the present study, eighty-three wild Oreochromis aureus of different body size ranging 5.3-14.6 cm in total length were collected from the River Chenab, District Muzzafer Garh, Pakistan to investigate the parameters of length –weight, length-length relationships and condition factor in relation to size.

CA suffers from high degree of water permeability as well as the low thermal stability at high temperatures. To adjust the CA polymeric films to the manufacture of food packaging, its thermal and mechanical properties should be improved. The modification of CA by grafting it with N-Amino phenyl maleimide (N-APhM) led to the construction of hydrophobic branches throughout the polymeric matrix which reduced its wettability as compared to the parent CA. The branches built onto the polymeric chains had been characterized by UV/Vis, <sup>13</sup>C-NMR and ESEM. The improvement of the thermal properties was investigated and compared to the parent CA using thermal gravimetric analysis (TGA), differential scanning calorimetry (DSC), differential thermal analysis (DTA), contact angle and mechanical testing measurements. The results revealed that the water-uptake was reduced by increasing the graft percentage. The thermal and mechanical properties were also improved. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=cellulose%20acetate" title="cellulose acetate">cellulose acetate</a>, <a href="https://publications.waset.org/abstracts/search?q=food%20packaging" title=" food packaging"> food packaging</a>, <a href="https://publications.waset.org/abstracts/search?q=graft%20copolymerization" title=" graft copolymerization"> graft copolymerization</a>, <a href="https://publications.waset.org/abstracts/search?q=thermal%20properties" title=" thermal properties"> thermal properties</a> </p> <a href="https://publications.waset.org/abstracts/88229/biodegradable-cellulose-based-materials-for-the-use-in-food-packaging" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/88229.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">222</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">96</span> Effect of Boric Acid Content on the Structural and Optical Properties of In2O3 Films Prepared by Spray Pyrolysis Technique</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mustafa%20%C3%96ztas">Mustafa Öztas</a>, <a href="https://publications.waset.org/abstracts/search?q=Metin%20Bedir"> Metin Bedir</a>, <a href="https://publications.waset.org/abstracts/search?q=Yahya%20%C3%96zdemir"> Yahya Özdemir</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Boron doped of In2O3 films were prepared by spray pyrolysis technique at 350 °C substrate temperature, which is a low cost and large area technique to be well-suited for the manufacture of solar cells, using boric acid (H3BO3) as dopant source, and their properties were investigated as a function of doping concentration.

This mechanism builds on the role of phase heads as both the loci of spell-out features and the transfer triggers via either Phase Impenetrability Condition 1 (PIC1) and/or Phase Impenetrability Condition 2 (PIC2). The assumption here is that phase heads, mainly v*, can regulate the spell-out process by deciding both the type of spell-out applying and the timing of spell-out relevant. This paper also proposes a new form of the constraint Wrap call it Wrap-XP’ and it is assumed to apply to IP as a functional maximal projection. This extension is shown to fall as a natural result once we assume the new theory of phases and multiple spell-out. Moreover, it is proposed in this work that some forms of XP movement are not motivated by an EPP feature of a strong phase head mainly v*, but they are rather motivated by a last resort strategy to accomplish the spell-out instruction of this phase head. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=linguistics" title="linguistics">linguistics</a>, <a href="https://publications.waset.org/abstracts/search?q=syntax" title=" syntax"> syntax</a>, <a href="https://publications.waset.org/abstracts/search?q=phonology" title=" phonology"> phonology</a>, <a href="https://publications.waset.org/abstracts/search?q=phase%20theory" title=" phase theory"> phase theory</a>, <a href="https://publications.waset.org/abstracts/search?q=optimality%20theory" title=" optimality theory"> optimality theory</a> </p> <a href="https://publications.waset.org/abstracts/37580/a-new-spell-out-mechanism" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/37580.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">514</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">94</span> Analytical Solution for End Depth Ratio in Rectangular Channels</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Abdulrahman%20Abdulrahman">Abdulrahman Abdulrahman</a>, <a href="https://publications.waset.org/abstracts/search?q=Abir%20Abdulrahman"> Abir Abdulrahman</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Free over-fall is an instrument for measuring discharge in open channels by measuring end depth. A comprehensive researchers investigated theoretically and experimentally brink phenomenon with various approaches for different cross-sectional shapes. Anderson's method, based on Boussinq's approximation and energy approach was used to derive a pressure distribution factor at end depth. Applying the one-dimensional momentum equation and the principles of limit slope analysis, a relevant analytical solution may be derived for brink depth ratio (EDR) in prismatic rectangular channel. Also relationships between end depth ratio and slope ratio for a given non-dimensional normal or critical depth with upstream supercritical flow regime are presented. Simple indirect procedure is used to estimate the end depth discharge ratio (EDD) for subcritical and supercritical flow using measured end depth.

The change points were successfully located. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=binary%20segmentation" title="binary segmentation">binary segmentation</a>, <a href="https://publications.waset.org/abstracts/search?q=change%20point" title=" change point"> change point</a>, <a href="https://publications.waset.org/abstracts/search?q=exponentialLomax%20%20distribution" title=" exponentialLomax distribution"> exponentialLomax distribution</a>, <a href="https://publications.waset.org/abstracts/search?q=information%20%20criterion" title=" information criterion"> information criterion</a> </p> <a href="https://publications.waset.org/abstracts/145911/change-point-analysis-in-average-ozone-layer-temperature-using-exponential-lomax-distribution" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/145911.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">175</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">91</span> Insecticidal Effects of Plant Extracts of Thymus daenensis and Eucalyptus camaldulensis on Callosobruchus maculatus (Coleoptera: Bruchidae)</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Afsoon%20Danesh%20Afrooz">Afsoon Danesh Afrooz</a>, <a href="https://publications.waset.org/abstracts/search?q=Sohrab%20Imani"> Sohrab Imani</a>, <a href="https://publications.waset.org/abstracts/search?q=Ali%20Ahadiyat"> Ali Ahadiyat</a>, <a href="https://publications.waset.org/abstracts/search?q=Aref%20Maroof"> Aref Maroof</a>, <a href="https://publications.waset.org/abstracts/search?q=Yahya%20Ostadi"> Yahya Ostadi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This study has been investigated for finding alternative and safe botanical pesticides instead of chemical insecticides. The effects of plant extracts of Eucalyptus camaldulensis and Thymus daenensis were tested against adult of Callosobrochus maculatus F. Experiments were carried out at 27±1°C and 60 ± 5% R. H. under dark condition with adopting a complete randomized block design. Three replicates were set up for five concentrations of each plants extract. LC50 values were determined by SPSS 16.0 software. LC50 values indicated that plant extract of Thymus daenensis with 1.708 (µl/l air) against adult was more effective than the plant extract of Eucalyptus camaldulensis with LC50 12.755 (µl/l air). It was found that plant extract of Thymus daenensis in comparison with extract of Eucalyptus camaldulensis could be used as a pesticide for control store pests. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=callosobruchus%20maculatus" title="callosobruchus maculatus">callosobruchus maculatus</a>, <a href="https://publications.waset.org/abstracts/search?q=Eucalyptus%20camaldulensis" title=" Eucalyptus camaldulensis"> Eucalyptus camaldulensis</a>, <a href="https://publications.waset.org/abstracts/search?q=insecticidal%20effects" title=" insecticidal effects"> insecticidal effects</a>, <a href="https://publications.waset.org/abstracts/search?q=Thymus%20daenensis" title=" Thymus daenensis"> Thymus daenensis</a> </p> <a href="https://publications.waset.org/abstracts/16007/insecticidal-effects-of-plant-extracts-of-thymus-daenensis-and-eucalyptus-camaldulensis-on-callosobruchus-maculatus-coleoptera-bruchidae" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/16007.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">326</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">90</span> Analysis of Potential Flow around Two-Dimensional Body by Surface Panel Method and Vortex Lattice Method</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=M.%20Abir%20Hossain">M.

The Laplace equation was solved at each panel by applying the boundary conditions. The boundary condition was applied at each panel to mathematically formulate the problem and then convert the problem into a computer-solvable problem. Kutta condition was applied at both the leading and trailing edges to see whether the condition is satisfied or not. Another approach that is applied for the analysis is Vortex Lattice Method (VLM). A vortex ring is considered at each control point. Using the Biot-Savart Law the strength at each control point is calculated and hence the pressure differentials are measured. For the comparison of the analytic result with the experimental result, different NACA section hydrofoil is used. The analytic result of NACA 0012 and NACA 0015 are compared with the experimental result of Abbott and Doenhoff and found significant conformity with the achieved result. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Kutta%20condition" title="Kutta condition">Kutta condition</a>, <a href="https://publications.waset.org/abstracts/search?q=Law%20of%20Biot-Savart" title=" Law of Biot-Savart"> Law of Biot-Savart</a>, <a href="https://publications.waset.org/abstracts/search?q=pressure%20differentials" title=" pressure differentials"> pressure differentials</a>, <a href="https://publications.waset.org/abstracts/search?q=potential%20flow" title=" potential flow"> potential flow</a>, <a href="https://publications.waset.org/abstracts/search?q=vortex%20lattice%20method" title=" vortex lattice method"> vortex lattice method</a> </p> <a href="https://publications.waset.org/abstracts/81177/analysis-of-potential-flow-around-two-dimensional-body-by-surface-panel-method-and-vortex-lattice-method" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/81177.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">190</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">89</span> Isolation of Biosurfactant Producing Spore-Forming Bacteria from Oman: Potential Applications in Bioremediation</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Saif%20N.%20Al-Bahry">Saif N.

One possible application of microbial product -biosurfactant is in bioremediation of hydrocarbon contaminated sites. We have screened forty two different petroleum contaminated sites from Oman, for biosurfactant producing spore-forming bacterial isolates. Initial screening showed that out of 42 soil samples, three showed reduction in surface tension (ST) and interfacial tension (IFT) within 24h of incubation at 40°C. Out of those 3 soil samples, one was further selected for isolation of bacteria and 14 different bacteria were isolated in pure form. Of those 14 spore-forming, rod shaped bacteria, two showed highest reduction in ST and IFT in the range of 70mN/m to < 35mN/m and 26.69mN/m to < 9mN/m, respectively within 24h. These bacterial biosurfactants may be utilized for bioremediation of oil-spills. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=bioremediation" title="bioremediation">bioremediation</a>, <a href="https://publications.waset.org/abstracts/search?q=hydrocarbon%20pollution" title=" hydrocarbon pollution"> hydrocarbon pollution</a>, <a href="https://publications.waset.org/abstracts/search?q=spore-forming%20bacteria" title=" spore-forming bacteria"> spore-forming bacteria</a>, <a href="https://publications.waset.org/abstracts/search?q=bio-surfactant" title=" bio-surfactant"> bio-surfactant</a> </p> <a href="https://publications.waset.org/abstracts/3715/isolation-of-biosurfactant-producing-spore-forming-bacteria-from-oman-potential-applications-in-bioremediation" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/3715.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">297</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">88</span> A Supervised Goal Directed Algorithm in Economical Choice Behaviour: An Actor-Critic Approach</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Keyvanl%20Yahya">Keyvanl Yahya</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper aims to find a algorithmic structure that affords to predict and explain economic choice behaviour particularly under uncertainty (random policies) by manipulating the prevalent Actor-Critic learning method that complies with the requirements we have been entrusted ever since the field of neuroeconomics dawned on us. Whilst skimming some basics of neuroeconomics that might be relevant to our discussion, we will try to outline some of the important works which have so far been done to simulate choice making processes. Concerning neurological findings that suggest the existence of two specific functions that are executed through Basal Ganglia all the way down to sub-cortical areas, namely 'rewards' and 'beliefs', we will offer a modified version of actor/critic algorithm to shed a light on the relation between these functions and most importantly resolve what is referred to as a challenge for actor-critic algorithms, that is lack of inheritance or hierarchy which avoids the system being evolved in continuous time tasks whence the convergence might not emerge. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=neuroeconomics" title="neuroeconomics">neuroeconomics</a>, <a href="https://publications.waset.org/abstracts/search?q=choice%20behaviour" title=" choice behaviour"> choice behaviour</a>, <a href="https://publications.waset.org/abstracts/search?q=decision%20making" title=" decision making"> decision making</a>, <a href="https://publications.waset.org/abstracts/search?q=reinforcement%20learning" title=" reinforcement learning"> reinforcement learning</a>, <a href="https://publications.waset.org/abstracts/search?q=actor-critic%20algorithm" title=" actor-critic algorithm"> actor-critic algorithm</a> </p> <a href="https://publications.waset.org/abstracts/4292/a-supervised-goal-directed-algorithm-in-economical-choice-behaviour-an-actor-critic-approach" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/4292.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">397</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">87</span> Evaluating the Durability and Safety of Lithium-Ion Batterie in High-Temperature Desert Climates</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Kenza%20Maher">Kenza Maher</a>, <a href="https://publications.waset.org/abstracts/search?q=Yahya%20Zakaria"> Yahya Zakaria</a>, <a href="https://publications.waset.org/abstracts/search?q=Noora%20S.%20Al-Jaidah"> Noora S.

In this study, four commercially available 18650 lithium-ion cells from four different manufacturers are subjected to accelerated cycle aging for up to 500 cycles at two different temperatures (25°C and 45°C). The cells are also calendar-aged at the same temperatures in both charged and discharged states for 6 months to investigate the effect of aging and temperature on capacity fade and state of health. The results showed that all battery cells demonstrated good cyclability and had a good state of health at both temperatures. However, the capacity loss and state of health of these cells are found to be dependent on the cell chemistry and aging conditions, including temperature. Specifically, the capacity loss is found to be higher at the higher aging temperature, indicating the significant impact of temperature on the aging of lithium-ion batteries. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=lithium-ion%20battery" title="lithium-ion battery">lithium-ion battery</a>, <a href="https://publications.waset.org/abstracts/search?q=aging%20mechanisms" title=" aging mechanisms"> aging mechanisms</a>, <a href="https://publications.waset.org/abstracts/search?q=cycle%20aging" title=" cycle aging"> cycle aging</a>, <a href="https://publications.waset.org/abstracts/search?q=calendar%20aging." title=" calendar aging."> calendar aging.</a> </p> <a href="https://publications.waset.org/abstracts/165119/evaluating-the-durability-and-safety-of-lithium-ion-batterie-in-high-temperature-desert-climates" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/165119.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">99</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">86</span> Real-Time Episodic Memory Construction for Optimal Action Selection in Cognitive Robotics</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Deon%20de%20Jager">Deon de Jager</a>, <a href="https://publications.waset.org/abstracts/search?q=Yahya%20Zweiri"> Yahya Zweiri</a>, <a href="https://publications.waset.org/abstracts/search?q=Dimitrios%20Makris"> Dimitrios Makris</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The three most important components in the cognitive architecture for cognitive robotics is memory representation, memory recall, and action-selection performed by the executive. In this paper, action selection, performed by the executive, is defined as a memory quantification and optimization process. The methodology describes the real-time construction of episodic memory through semantic memory optimization. The optimization is performed by set-based particle swarm optimization, using an adaptive entropy memory quantification approach for fitness evaluation. The performance of the approach is experimentally evaluated by simulation, where a UAV is tasked with the collection and delivery of a medical package. The experiments show that the UAV dynamically uses the episodic memory to autonomously control its velocity, while successfully completing its mission. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=cognitive%20robotics" title="cognitive robotics">cognitive robotics</a>, <a href="https://publications.waset.org/abstracts/search?q=semantic%20memory" title=" semantic memory"> semantic memory</a>, <a href="https://publications.waset.org/abstracts/search?q=episodic%20memory" title=" episodic memory"> episodic memory</a>, <a href="https://publications.waset.org/abstracts/search?q=maximum%20entropy%20principle" title=" maximum entropy principle"> maximum entropy principle</a>, <a href="https://publications.waset.org/abstracts/search?q=particle%20swarm%20optimization" title=" particle swarm optimization"> particle swarm optimization</a> </p> <a href="https://publications.waset.org/abstracts/114710/real-time-episodic-memory-construction-for-optimal-action-selection-in-cognitive-robotics" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/114710.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">156</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">85</span> IT and Security Experts' Innovation and Investment Front for IT-Entrepreneurship in Pakistan</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ahmed%20Mateen">Ahmed Mateen</a>, <a href="https://publications.waset.org/abstracts/search?q=Zhu%20Qingsheng"> Zhu Qingsheng</a>, <a href="https://publications.waset.org/abstracts/search?q=Muhammad%20Awais"> Muhammad Awais</a>, <a href="https://publications.waset.org/abstracts/search?q=Muhammad%20Yahya%20Saeed"> Muhammad Yahya Saeed</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper targets the rising factor of entrepreneurship innovation, which lacks in Pakistan as compared to the other countries or the regions like China, India, and Malaysia, etc. This is an exploratory and explanatory study. Major aspects have identified as the direction for the policymakers while highlighting the issues in true spirit. IT needs to be considered not only as a technology but also as itself growing as a new community. IT management processes are complex and broad, so generally requires extensive attention to the collective aspects of human variables, capital and technology. In addition, projects tend to have a special set of critical success factors, and if these are processed and given attention, it will improve the chances of successful implementation. This is only possible with state of the art intelligent decision support systems and accumulating IT staff to some extent in decision processes.

In this paper, using a soft switching approach, we investigate the effect of weather inhomogeneities on the strength of turbulence hence the channel refractive index under Qatar harsh environment and their influence on the hybrid FSO/RF availability. In this approach, either FSO/RF or simultaneous or none of them can be active. Based on soft switching approach and a finite state Markov Chain (FSMC) process, we model the channel fading for the two links and derive a mathematical expression for the outage probability of the hybrid system. Then, we evaluate the behavior of the hybrid FSO/RF under hazy and harsh weather. Results show that the FSO/RF soft switching renders the system outage probability less than that of each link individually. A soft switching algorithm is being implemented on FPGAs using Raptor code interfaced to the two terminals of a 1Gbps/100 Mbps FSO/RF hybrid system, the first being implemented in the region.

Fifty-four male rats (230-250 g) were allocated into 3 treatment groups (each include 3 groups and 6 replicate). Group 1 served as water control. In group 2, rats were gavaged with 60 mg/kg garlic juice. In group 3, rats were offered 120 mg/kg garlic juice. Animals received treatments orally and ad libitum access to chow pellets and fresh water. After 4 weeks, animals were killed, testes were taken out and semen samples were used to determine MDA, SOD, GPx and TAS activity. According to the results, garlic juice (120 mg/kg) significantly declined semen MDA activity compared to control group (P<0.05). These results suggest that presumably garlic juice protects semen oxidation in rat testes. <p class="card-text"><strong>Keywords:</strong> <a
