Naturally, business applications would require the deployment of various RFID systems that are developed by different vendors and use various data formats. This heterogeneity poses a real challenge in developing large-scale IoT systems with RFID as integration is becoming very complex and challenging. Semantic integration is a key approach to deal with this challenge. To do so, ontology for RFID systems need to be developed in order to annotated semantically RFID systems, and hence, facilitate their integration. Accordingly, in this paper, we propose ontology for RFID systems. The proposed ontology can be used to semantically enrich RFID systems, and hence, improve their usage and reasoning. The usage of the proposed ontology is explained through a simple scenario in the health care domain. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=RFID" title="RFID">RFID</a>, <a href="https://publications.waset.org/abstracts/search?q=semantic%20technology" title=" semantic technology"> semantic technology</a>, <a href="https://publications.waset.org/abstracts/search?q=ontology" title=" ontology"> ontology</a>, <a href="https://publications.waset.org/abstracts/search?q=sparql%20query%20language" title=" sparql query language"> sparql query language</a>, <a href="https://publications.waset.org/abstracts/search?q=heterogeneity" title=" heterogeneity"> heterogeneity</a> </p> <a href="https://publications.waset.org/abstracts/39376/an-ontology-for-semantic-enrichment-of-rfid-systems" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/39376.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">471</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">307</span> Promoters' Perspectives on the Impact of Development Projects: Do They Suffer from Any Forms of Social Injustice?</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ola%20Hosny">Ola Hosny</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper illustrates promoters’ role in any development project and factors affecting their performance. The paper starts by giving an overview of the Egyptian context and the born of non-formal education. This is then followed by answers to the following questions; who are promoters, why build promoters’ skills, do promoters suffer from any forms of social injustice, what is meant by leadership’s skills, why build promoters’ leadership skills in specific, and finally what is the desired final destination. Given the fact that promoters are the actual implementers on ground of any project, this paper pinpoints the extent to which promoters' capacities should be developed to institutionalize projects' values into the community, transfer knowledge, and be able to act as pillars of change to sustain the maximum achievements from any intervention, illustrating the role of education for sustainable development.

Besides, it contain many vitamins as well as minerals which are important for the human body. Therefore, a total of 150 frozen chicken meat product samples, 800g each within their shelf-life, were randomly collected from commercial markets from Egypt (75 samples) and Saudi Arabian (75 samples) for chemical evaluation. The mean values of fat% in the examined samples of Egyptian and Saudi markets were 16.0% and 4.6% for chicken burger; 15.0% and 11% for nuggets and 11% and 11% for strips respectively. The mean values of moisture % in the examined samples of Egyptian and Saudi markets were 67.0% and 81% for chicken burger; 66.0% and 78% for nuggets and 71.0% and 72% for strips respectively. The mean values of protein % in the examined samples of Egyptian and Saudi markets were 15% and 17% for chicken burger; 16% and 16% for nuggets and 16% and 17% for strips respectively. The obtained results were compared with the Egyptian slandered and suggestions for improving the chemical quality of chicken products were given. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=chicken%20meat" title="chicken meat">chicken meat</a>, <a href="https://publications.waset.org/abstracts/search?q=nutrition" title=" nutrition"> nutrition</a>, <a href="https://publications.waset.org/abstracts/search?q=Egypt" title=" Egypt"> Egypt</a>, <a href="https://publications.waset.org/abstracts/search?q=markets" title=" markets"> markets</a> </p> <a href="https://publications.waset.org/abstracts/40108/nutritional-quality-of-partially-processed-chicken-meat-products-from-egyptian-and-saudi-arabia-markets" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/40108.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">568</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">304</span> Kinematic Behavior of Geogrid Reinforcements during Earthquakes</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ahmed%20Hosny%20Abdel-Rahman">Ahmed Hosny Abdel-Rahman</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohamed%20Abdel-Moneim"> Mohamed Abdel-Moneim</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Reinforced earth structures are generally subjected to cyclic loading generated from earthquakes. This paper presents a summary of the results and analyses of a testing program carried out in a large-scale multi-function geosynthetic testing apparatus that accommodates soil samples up to 1.0 m3. This apparatus performs different shear and pullout tests under both static and cyclic loading. The testing program was carried out to investigate the controlling factors affecting soil/geogrid interaction under cyclic loading. The extensibility of the geogrids, the applied normal stresses, the characteristics of the cyclic loading (frequency, and amplitude), and initial static load within the geogrid sheet were considered in the testing program. Based on the findings of the testing program, the effect of these parameters on the pullout resistance of geogrids, as well as the displacement mobility under cyclic loading were evaluated. Conclusions and recommendations for the design of reinforced earth walls under cyclic loading are presented. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=geogrid" title="geogrid">geogrid</a>, <a href="https://publications.waset.org/abstracts/search?q=soil" title=" soil"> soil</a>, <a href="https://publications.waset.org/abstracts/search?q=interface" title=" interface"> interface</a>, <a href="https://publications.waset.org/abstracts/search?q=cyclic%20loading" title=" cyclic loading"> cyclic loading</a>, <a href="https://publications.waset.org/abstracts/search?q=pullout" title=" pullout"> pullout</a>, <a href="https://publications.waset.org/abstracts/search?q=large%20scale%20testing" title=" large scale testing"> large scale testing</a> </p> <a href="https://publications.waset.org/abstracts/30799/kinematic-behavior-of-geogrid-reinforcements-during-earthquakes" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/30799.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">622</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">303</span> The Usage of Nitrogen Gas and Alum for Sludge Dewatering</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mamdouh%20Yousef%20Saleh">Mamdouh Yousef Saleh</a>, <a href="https://publications.waset.org/abstracts/search?q=Medhat%20Hosny%20El-Zahar"> Medhat Hosny El-Zahar</a>, <a href="https://publications.waset.org/abstracts/search?q=Shymaa%20El-Dosoky"> Shymaa El-Dosoky</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In most cases, the associated processing cost of dewatering sludge increase with the solid particles concentration. All experiments in this study were conducted on biological sludge type. All experiments help to reduce the greenhouse gases in addition, the technology used was faster in time and less in cost compared to other methods. First, the bubbling pressure was used to dissolve N₂ gas into the sludge, second alum was added to accelerate the process of coagulation of the sludge particles and facilitate their flotation, and third nitrogen gas was used to help floating the sludge particles and reduce the processing time because of the nitrogen gas from the inert gases. The conclusions of this experiment were as follows: first, the best conditions were obtained when the bubbling pressure was 0.6 bar. Second, the best alum dose was determined to help the sludge agglomerate and float. During the experiment, the best alum dose was 80 mg/L. It increased concentration of the sludge by 7-8 times. Third, the economic dose of nitrogen gas was 60 mg/L with separation efficiency of 85%. The sludge concentration was about 8-9 times. That happened due to the gas released tiny bubbles which adhere to the suspended matter causing them to float to the surface of the water where it could be then removed. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=nitrogen%20gas" title="nitrogen gas">nitrogen gas</a>, <a href="https://publications.waset.org/abstracts/search?q=biological%20treatment" title=" biological treatment"> biological treatment</a>, <a href="https://publications.waset.org/abstracts/search?q=alum" title=" alum"> alum</a>, <a href="https://publications.waset.org/abstracts/search?q=dewatering%20sludge" title=" dewatering sludge"> dewatering sludge</a>, <a href="https://publications.waset.org/abstracts/search?q=greenhouse%20gases" title=" greenhouse gases"> greenhouse gases</a> </p> <a href="https://publications.waset.org/abstracts/104794/the-usage-of-nitrogen-gas-and-alum-for-sludge-dewatering" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/104794.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">217</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">302</span> Its about Cortana, Microsoft’s Virtual Assistant</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Aya%20Idriss">Aya Idriss</a>, <a href="https://publications.waset.org/abstracts/search?q=Esraa%20Othman"> Esraa Othman</a>, <a href="https://publications.waset.org/abstracts/search?q=Lujain%20Malak"> Lujain Malak</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Artificial intelligence is the emulation of human intelligence processes by machines, particularly computer systems that act logically. Some of the specific applications of AI include natural language processing, speech recognition, and machine vision. Cortana is a virtual assistant and she’s an example of an AI Application. Microsoft made it possible for this app to be accessed not only on laptops and PCs but can be downloaded on mobile phones and used as a virtual assistant which was a huge success. Cortana can offer a lot apart from the basic orders such as setting alarms and marking the calendar. Its capabilities spread past that, for example, it provides us with listening to music and podcasts on the go, managing my to-do list and emails, connecting with my contacts hands-free by simply just telling the virtual assistant to call somebody, gives me instant answers and so on. A questionnaire was sent online to numerous friends and family members to perform the study, which is critical in evaluating Cortana's recognition capacity and the majority of the answers were in favor of Cortana’s capabilities. The results of the questionnaire assisted us in determining the level of Cortana's skills. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=artificial%20intelligence" title="artificial intelligence">artificial intelligence</a>, <a href="https://publications.waset.org/abstracts/search?q=Cortana" title=" Cortana"> Cortana</a>, <a href="https://publications.waset.org/abstracts/search?q=AI" title=" AI"> AI</a>, <a href="https://publications.waset.org/abstracts/search?q=abstract" title=" abstract"> abstract</a> </p> <a href="https://publications.waset.org/abstracts/145049/its-about-cortana-microsofts-virtual-assistant" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/145049.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">301</span> 3D Modelling of Fluid Flow in Tunnel Kilns</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Jaber%20H.%20Almutairi">Jaber H.

The CFD simulations are carried out with the FLUENT software and validated against experimental results on fluid flow and heat transfer in tunnel kilns. A grid dependency study is conducted in the current work to improve the accuracy of the results. Three turbulence models k–ω, standard k–ε, and RNG k–ε are tested where k–ω model gives the best results in comparison with the experiment. The numerical results reveal an intriguing phenomenon where a long flow separation zone behind the setting is observed under different geometric and operation conditions. It was found that the uniformity of flow distribution can be substantially improved by rearranging the geometrical parameters of brick setting relative to kiln/setting. This improvement of flow distribution plays a critical role to enhance the quality and quantity of the production. It can be concluded that a better design and operation of tunnel kilns in terms of productivity and energy consumption can be obtained by taking into consideration the flow uniformity inside the tunnel kilns using CFD modelling. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=tunnel%20kilns" title="tunnel kilns">tunnel kilns</a>, <a href="https://publications.waset.org/abstracts/search?q=flow%20separation" title=" flow separation"> flow separation</a>, <a href="https://publications.waset.org/abstracts/search?q=flow%20uniformity" title=" flow uniformity"> flow uniformity</a>, <a href="https://publications.waset.org/abstracts/search?q=computational%20fluid%20dynamics" title=" computational fluid dynamics"> computational fluid dynamics</a> </p> <a href="https://publications.waset.org/abstracts/62902/3d-modelling-of-fluid-flow-in-tunnel-kilns" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/62902.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">329</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">300</span> Violence and Unintentional Injuries among Secondary School Students in Jordan</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Malakeh%20Zuhdi%20Malak">Malakeh Zuhdi Malak</a>, <a href="https://publications.waset.org/abstracts/search?q=Mahmoud%20Taher%20Kalaldeh"> Mahmoud Taher Kalaldeh</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In Jordan, no available data exists regarding violence and unintentional injuries among secondary school students aged 15-19 years. The purpose of this study was to assess the violence and unintentional injuries among those students, and to compare these two behaviors between male and female students. A descriptive cross-sectional design was carried out on randomly selected eight comprehensive secondary schools (four schools for females and four schools for males) from the public school educational directorate located in Amman. A modified Arabic version of the General School Health Survey questionnaire was used to measure violence and unintentional injuries. A sample of 750 secondary school students was studied. The findings showed that 26.8 % of students had been physically attacked. Overall, 43.3 % of students had been involved in a physical fight and 20.1% of them had been bullied. Overall, 45.3% of students were seriously injured. There was a difference between male and female students regarding to physical attack, physical fight, and serious injuries. In conclusion, it is necessary to develop effective training program in life skills for students that functions to reduce risk-taking behaviors that often leading to violence and unintentional injuries. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=secondary%20school%20students" title="secondary school students">secondary school students</a>, <a href="https://publications.waset.org/abstracts/search?q=violence" title=" violence"> violence</a>, <a href="https://publications.waset.org/abstracts/search?q=unintentional%20injuries" title=" unintentional injuries"> unintentional injuries</a>, <a href="https://publications.waset.org/abstracts/search?q=bullying" title=" bullying"> bullying</a> </p> <a href="https://publications.waset.org/abstracts/26417/violence-and-unintentional-injuries-among-secondary-school-students-in-jordan" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/26417.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">372</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">299</span> Improvement of Data Transfer over Simple Object Access Protocol (SOAP)</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Khaled%20Ahmed%20Kadouh">Khaled Ahmed Kadouh</a>, <a href="https://publications.waset.org/abstracts/search?q=Kamal%20Ali%20Albashiri"> Kamal Ali Albashiri</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper presents a designed algorithm involves improvement of transferring data over Simple Object Access Protocol (SOAP).

Stir followed by squeeze casting techniques are used to produce A359 composites. It was noticed that, A359/AlN composites have high thermal conductivity as compared to A359 alloy and even to A359/SiC or A359/(SiC+Si3N4) composites. Microstructures of the composites have shown homogeneous and even distribution of reinforcements within the matrix. Interfacial reactions between particles and matrix were investigated using X-ray diffraction and energy dispersive X-ray analysis. The presence of particles led not only to increase peak hardness of the composites but also to accelerate the aging kinetics. As compared with A359 matrix alloy, compression test of the composites has exhibited a significant increase in the yield and the ultimate compressive strengths with a relative reduction in the failure strain. Those light weight composites have a high potential to be used for automotive and aerospace applications. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=metal-matrix%20composite" title="metal-matrix composite">metal-matrix composite</a>, <a href="https://publications.waset.org/abstracts/search?q=squeeze" title=" squeeze"> squeeze</a>, <a href="https://publications.waset.org/abstracts/search?q=microstructure" title=" microstructure"> microstructure</a>, <a href="https://publications.waset.org/abstracts/search?q=thermal%20conductivity" title=" thermal conductivity"> thermal conductivity</a>, <a href="https://publications.waset.org/abstracts/search?q=compressive%20properties" title=" compressive properties"> compressive properties</a> </p> <a href="https://publications.waset.org/abstracts/66981/a-comparative-study-of-microstructure-thermal-and-mechanical-properties-of-a359-composites-reinforced-with-sic-si3n4-and-aln-particles" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/66981.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">381</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">297</span> Investigating the Impact of Solar Radiation on Electricity Meters’ Accuracy Using A Modified Climatic Chamber</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Hala%20M.%20Abdel%20Mageed">Hala M.

In this work, the (MKF-240) climatic chamber has been modified to act as a solar simulator at the Egyptian national institute of standard, NIS. Quartz Tungsten Halogen (QTH) lamps and an Aluminum plate are added to the climatic chamber to realize the solar test conditions. Many experimental trials have been performed to reach the optimum number of lamps needed to fulfil the test requirements and to adjust the best uniform test area. The proposed solar simulator design is capable to produce irradiance up to 1066 W/m2. Its output radiation is controlled by changing the number of illuminated lamps as well as changing the distance between lamps and tested electricity meter. The uniformity of radiation within the simulator has been recognized to be 91.5 % at maximum irradiance. Three samples of electricity meters have been tested under different irradiances, temperatures, and electric loads. The electricity meters’ accuracies have been recorded and analyzedfor eachsample. Moreover, measurement uncertainty contribution has been considered in all tests to get precision value. There were noticeable changes in the accuracies of the electricity meters while exposed to solar radiation, although there were no noticeable distortions of their insulationsand outer surfaces. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=solar%20radiation" title="solar radiation">solar radiation</a>, <a href="https://publications.waset.org/abstracts/search?q=solar%20simulator" title=" solar simulator"> solar simulator</a>, <a href="https://publications.waset.org/abstracts/search?q=climatic%20chamber" title=" climatic chamber"> climatic chamber</a>, <a href="https://publications.waset.org/abstracts/search?q=halogen%20lamp" title=" halogen lamp"> halogen lamp</a>, <a href="https://publications.waset.org/abstracts/search?q=electricity%20meter" title=" electricity meter"> electricity meter</a> </p> <a href="https://publications.waset.org/abstracts/152458/investigating-the-impact-of-solar-radiation-on-electricity-meters-accuracy-using-a-modified-climatic-chamber" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/152458.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">127</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">296</span> Survey of Web Service Composition</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Wala%20Ben%20Messaoud">Wala Ben Messaoud</a>, <a href="https://publications.waset.org/abstracts/search?q=Khaled%20Ghedira"> Khaled Ghedira</a>, <a href="https://publications.waset.org/abstracts/search?q=Youssef%20Ben%20Halima"> Youssef Ben Halima</a>, <a href="https://publications.waset.org/abstracts/search?q=Henda%20Ben%20Ghezala"> Henda Ben Ghezala</a> </p> <p class="card-text"><strong>Abstract:</strong></p> A web service (WS) is called compound or composite when its execution involves interactions with other WS to use their features.

More specifically, the problem is concerned with finding a permutation that minimizes the sum of distances between itself and a set of three signed permutations. Genomes with equal number of genes but different order can be represented as permutations. In this paper, an algorithm, namely BeamGA median, is proposed that combines a heuristic search approach (local beam) as an initialization step to generate a number of solutions, and then a Genetic Algorithm (GA) is applied in order to refine the solutions, aiming to achieve a better median with the smallest possible reversal distance from the three original permutations. In this approach, any genome rearrangement distance can be applied. In this paper, we use the reversal distance. To the best of our knowledge, the proposed approach was not applied before for solving the median problem. Our approach considers true biological evolution scenario by applying the concept of common intervals during the GA optimization process. This allows us to imitate a true biological behavior and enhance genetic approach time convergence. We were able to handle permutations with a large number of genes, within an acceptable time performance and with same or better accuracy as compared to existing algorithms. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=median%20problem" title="median problem">median problem</a>, <a href="https://publications.waset.org/abstracts/search?q=phylogenetic%20tree" title=" phylogenetic tree"> phylogenetic tree</a>, <a href="https://publications.waset.org/abstracts/search?q=permutation" title=" permutation"> permutation</a>, <a href="https://publications.waset.org/abstracts/search?q=genetic%20algorithm" title=" genetic algorithm"> genetic algorithm</a>, <a href="https://publications.waset.org/abstracts/search?q=beam%20search" title=" beam search"> beam search</a>, <a href="https://publications.waset.org/abstracts/search?q=genome%20rearrangement%20distance" title=" genome rearrangement distance"> genome rearrangement distance</a> </p> <a href="https://publications.waset.org/abstracts/73026/beamga-median-a-hybrid-heuristic-search-approach" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/73026.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">265</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">293</span> Plant Cell Culture to Produce Valuable Natural Products</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Jehad%20Dumireih">Jehad Dumireih</a>, <a href="https://publications.waset.org/abstracts/search?q=Malak%20Dmirieh"> Malak Dmirieh</a>, <a href="https://publications.waset.org/abstracts/search?q=Michael%20Wink"> Michael Wink</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The present work is aimed to use plant cell suspension cultures of Crataegus monogyna for biosynthesis of valuable natural products by using quercetin as an inexpensive precursor. Suspension cell cultures of C. monogyna were established by using Murashige and Skoog medium (MS) supplemented with 1 mg/L 2,4-dichlorophenoxyacetic acid and 1 mg/L kinetin. Cells were harvested from the cultures and extracted by using methanol and ethyl acetate; then the extracts were used for the identification of isoquercetin by HPLC and by mass spectrometry. The incubation of the cells with 0.24 mM quercetin for one week resulted in an 16 fold increase of isoquercetin biosynthesis; the growth rate of the cells increased by 20%. Moreover, the biosynthesis of isoquercetin was enhanced by 40% when we divided the added quercetin into three portions each one with concentration 0.12 mM supplied at 3 days intervals. In addition, we didn’t find any positive effects of adding different concentrations the precursors phenylalanine (0.2 mM) and galactose to the cell cultures. In conclusion, the efficiency of the biotransformation of quercetin into isoquercetin depended on the concentration quercetin, its incubation time and the way of its administration. The results of the present work suggest that the biotechnological methods such as cell suspension cultures could be successfully used to obtain highly valuable natural product starting from inexpensive compound. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=biosynthesis" title="biosynthesis">biosynthesis</a>, <a href="https://publications.waset.org/abstracts/search?q=biotransformation" title=" biotransformation"> biotransformation</a>, <a href="https://publications.waset.org/abstracts/search?q=Crataegus" title=" Crataegus"> Crataegus</a>, <a href="https://publications.waset.org/abstracts/search?q=isoquercetin" title=" isoquercetin"> isoquercetin</a> </p> <a href="https://publications.waset.org/abstracts/34551/plant-cell-culture-to-produce-valuable-natural-products" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/34551.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">499</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">292</span> Factors Influencing Site Overhead Cost of Construction Projects in Egypt: A Comparative Analysis</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Aya%20Effat">Aya Effat</a>, <a href="https://publications.waset.org/abstracts/search?q=Ossama%20A.%20Hosny"> Ossama A.

The precision of the cost estimate plays a significant role in the success of construction projects as it allows project managers to effectively manage the project's costs. Site overhead costs constitute a significant portion of construction project budgets, necessitating accurate prediction and management. These costs are influenced by a multitude of factors, requiring a thorough examination and analysis to understand their relative importance and impact. Thus, the main aim of this research is to enhance the contractor’s ability to predict and manage site overheads by identifying and analyzing the main factors influencing the site overheads costs in the Egyptian construction industry. Through a comprehensive literature review, key factors were first identified and subsequently validated using a thorough comparative analysis of data from 55 real-life construction projects. Through this comparative analysis, the relationship between each factor and site overheads percentage as well as each site overheads subcategory and each project construction phase was identified and examined. Furthermore, correlation analysis was done to check for multicollinearity and identify factors with the highest impact. The findings of this research offer valuable insights into the key drivers of site overhead costs in the Egyptian construction industry.

The behaviour of flexural strengthened steel I-beams using FRP was investigated. The finite element (FE) models were developed using ANSYS® as verification cases to simulate the experimental behaviour of using FRP strips to flexure strengthen steel I-beam. Two experimental studies were selected for verification; first examined the effect of different thicknesses and modulus of elasticity while the second studied the effect of applying different carbon fiber reinforced polymers (CFRP) bond lengths. The proposed FE models were in good agreement with the experimental results in terms of failure modes, load bearing capacities and strain distribution on CFRP strips. The verified FE models can be utilized to conduct a parametric study where various widths (40, 50, 60, 70 and 80 mm), thickness (1.2, 2 and 4 mm) and lengths (1500, 1700 and 1800 mm) of CFRP were analyzed. The results presented clearly revealed that the load bearing capacity was significantly increased (+7%) when the width and thickness were increased. However, load bearing capacity was slightly affected using longer CFRP strips. Moreover, applying another glass fiber reinforced polymers (GFRP) of 1500 mm in length, 50 mm in width and thicknesses of 1.2, 2 and 4 mm were investigated. Load bearing capacity of strengthened I-beams using GFRP is less than CFRP by average 8%. Statistical analysis has been conducted using Minitab®. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=FRP" title="FRP">FRP</a>, <a href="https://publications.waset.org/abstracts/search?q=strengthened%20steel%20I-beams" title=" strengthened steel I-beams"> strengthened steel I-beams</a>, <a href="https://publications.waset.org/abstracts/search?q=flexural" title=" flexural"> flexural</a>, <a href="https://publications.waset.org/abstracts/search?q=FEM" title=" FEM"> FEM</a>, <a href="https://publications.waset.org/abstracts/search?q=ANSYS" title=" ANSYS"> ANSYS</a> </p> <a href="https://publications.waset.org/abstracts/90119/flexural-strengthening-of-steel-beams-using-fiber-reinforced-polymers" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/90119.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">279</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">289</span> Phytochemical Investigation of Butanol Extract from Launeae Arborescens</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Khaled%20Sekoum">Khaled Sekoum</a>, <a href="https://publications.waset.org/abstracts/search?q=Nasser%20Belboukhari"> Nasser Belboukhari</a>, <a href="https://publications.waset.org/abstracts/search?q=Abelkrim%20Cheriti"> Abelkrim Cheriti</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Launeae arborescens (L. arborescens) is a medicinal plant having capacities of important propagation.

Every detail of a patient’s interactions with health care providers is maintained in Electronic Health Records (ECR) and Healthcare information systems (HIS). However, most of the existing systems are often focused on documenting what happens in manual health care process, rather than providing the highest quality patient care. Healthcare business processes and stakeholders can no longer rely on manual processes, to provide better patient care and efficient utilization of resources, Healthcare processes must be automated wherever it is possible. In this research, a detail survey and analysis is performed on the existing health care systems in Saudi Arabia, and an automated smart medical healthcare business process model is proposed. The business process management methods and rules are followed in discovering, collecting information, analysis, redesign, implementation and performance improvement analysis in terms of time and cost. From the simulation results, it is evident that our proposed smart medical records system can improve the quality of the service by reducing the time and cost and increasing efficiency <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=business%20process%20management" title="business process management">business process management</a>, <a href="https://publications.waset.org/abstracts/search?q=electronic%20health%20records" title=" electronic health records"> electronic health records</a>, <a href="https://publications.waset.org/abstracts/search?q=efficiency" title=" efficiency"> efficiency</a>, <a href="https://publications.waset.org/abstracts/search?q=cost" title=" cost"> cost</a>, <a href="https://publications.waset.org/abstracts/search?q=time" title=" time"> time</a> </p> <a href="https://publications.waset.org/abstracts/67697/an-automated-business-process-management-for-smart-medical-records" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/67697.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">287</span> Moho Undulations beneath South of Egypt, Using the Seismic Waves Generated by Tele Earthquakes</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ahmed%20Hosny">Ahmed Hosny</a>, <a href="https://publications.waset.org/abstracts/search?q=Haroon%20Elshaikh"> Haroon Elshaikh</a>, <a href="https://publications.waset.org/abstracts/search?q=Gaber%20Hassib"> Gaber Hassib</a>, <a href="https://publications.waset.org/abstracts/search?q=Yassin%20Ali"> Yassin Ali</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The Moho discontinuity undulations beneath the southern part of Egypt have been defined using the seismic waves generated by tele earthquakes. These earthquakes have been recorded by the Aswan seismic network, which consists of 10 seismic stations established around the lake of Nasser. An additional seismic station was located towards the east of the Lake of Nasser by about ~ 150 km. Receiver functions and H-k stacking methods were used for obtaining the depths of Moho discontinuity and the Vp/Vs ratios beneath each seismic station. Our results revealed that, the depths of Moho discontinuity beneath the stations located around the Lake of Nasser range from 36 to 39 km, with an average value of 37.5 km. These results are consistent with the previous works done on the same area. The obtained Vp/Vs ratios for the crust of this area were ranged from 1.73 to 1.86, with an average value of 1.79. While beneath the station located towards the east, the Moho discontinuity was detected at a shallowest depth of 27 km and the Vp/Vs ratio was 1.82. The difference in the Moho depths beneath the stations located around the Lake of Nasser and the station located to the east revealed the boundary position between the Saharan Metacraton to the west and the Nubian-Arabian Shield to the east. This structural boundary delineates the position of the old collision of the Oceanic crust of the Nubian-Arabian Shield to the east with the Continental crust of the Saharan Metacraton to the west. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Moho%20undulations" title="Moho undulations">Moho undulations</a>, <a href="https://publications.waset.org/abstracts/search?q=south%20of%20Egypt" title=" south of Egypt"> south of Egypt</a>, <a href="https://publications.waset.org/abstracts/search?q=seismic%20waves" title=" seismic waves"> seismic waves</a>, <a href="https://publications.waset.org/abstracts/search?q=earthquakes" title=" earthquakes"> earthquakes</a> </p> <a href="https://publications.waset.org/abstracts/36076/moho-undulations-beneath-south-of-egypt-using-the-seismic-waves-generated-by-tele-earthquakes" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/36076.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">512</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">286</span> Multi Agent Based Pre-Hospital Emergency Management Architecture</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Jaleh%20Shoshtarian%20Malak">Jaleh Shoshtarian Malak</a>, <a href="https://publications.waset.org/abstracts/search?q=Niloofar%20Mohamadzadeh"> Niloofar Mohamadzadeh</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Managing pre-hospital emergency patients requires real-time practices and efficient resource utilization. Since we are facing a distributed Network of healthcare providers, services and applications choosing the right resources and treatment protocol considering patient situation is a critical task. Delivering care to emergency patients at right time and with the suitable treatment settings can save ones live and prevent further complication. In recent years Multi Agent Systems (MAS) introduced great solutions to deal with real-time, distributed and complicated problems. In this paper we propose a multi agent based pre-hospital emergency management architecture in order to manage coordination, collaboration, treatment protocol and healthcare provider selection between different parties in pre-hospital emergency in a self-organizing manner. We used AnyLogic Agent Based Modeling (ABM) tool in order to simulate our proposed architecture. We have analyzed and described the functionality of EMS center, Ambulance, Consultation Center, EHR Repository and Quality of Care Monitoring as main collaborating agents. Future work includes implementation of the proposed architecture and evaluation of its impact on patient quality of care improvement. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=multi%20agent%20systems" title="multi agent systems">multi agent systems</a>, <a href="https://publications.waset.org/abstracts/search?q=pre-hospital%20emergency" title=" pre-hospital emergency"> pre-hospital emergency</a>, <a href="https://publications.waset.org/abstracts/search?q=simulation" title=" simulation"> simulation</a>, <a href="https://publications.waset.org/abstracts/search?q=software%20architecture" title=" software architecture"> software architecture</a> </p> <a href="https://publications.waset.org/abstracts/36272/multi-agent-based-pre-hospital-emergency-management-architecture" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/36272.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">426</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">285</span> Analysis of Total Quality Management (TQM) and Six Sigma in the Aerospace Industry</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Masimuddin%20Mohd%20Khaled">Masimuddin Mohd Khaled</a> </p> <p class="card-text"><strong>Abstract:</strong></p> From the past couple of years, focus has been done on the quality management theories and has been pertained to various firms.

This is open again opportunities for smart roads, smart traffic safety, and mobility comfort. A highly intelligent decision-making system is essential for autonomous driving around dense, dynamic objects. It must be able to handle complex road geometry and topology, as well as complex multiagent interactions, and closely follow higher-level commands such as routing information. Autonomous vehicles have become a very hot research topic in recent years due to their significant ability to reduce traffic accidents and personal injuries. Using new artificial intelligence-based technologies handles important functions in scene understanding, motion planning, decision making, vehicle control, social behavior, and communication for AV. This paper focuses only on deep reinforcement learning-based methods; it does not include traditional (flat) planar techniques, which have been the subject of extensive research in the past because reinforcement learning (RL) has become a powerful learning framework now capable of learning complex policies in high dimensional environments. The DRL algorithm used so far found solutions to the four main problems of autonomous driving; in our paper, we highlight the challenges and point to possible future research directions. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=deep%20reinforcement%20learning" title="deep reinforcement learning">deep reinforcement learning</a>, <a href="https://publications.waset.org/abstracts/search?q=autonomous%20driving" title=" autonomous driving"> autonomous driving</a>, <a href="https://publications.waset.org/abstracts/search?q=deep%20deterministic%20policy%20gradient" title=" deep deterministic policy gradient"> deep deterministic policy gradient</a>, <a href="https://publications.waset.org/abstracts/search?q=deep%20Q-learning" title=" deep Q-learning"> deep Q-learning</a> </p> <a href="https://publications.waset.org/abstracts/166548/deep-reinforcement-learning-model-for-autonomous-driving" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/166548.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">85</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">282</span> Coffee Consumption: Predictors, Prevalence, Awareness, and Trend among Saudi University Students</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Nasiruddin%20Khan">Nasiruddin Khan</a>, <a href="https://publications.waset.org/abstracts/search?q=Hanan%20A.%20Alfawaz"> Hanan A.

However, its excessive intake might exert negative effects. Our objective was to demonstrate the prevalence and awareness of coffee consumption among Saudi students and its determinants among this section of the population. Nine hundred thirty female students participated from various departments of King Saud University in a survey-based study using a face-to-face interview. The study demonstrates a high prevalence of coffee consumption (88.2%) among students in the Riyadh region. Certain situations such as exams were associated with increased frequency of coffee intake combined with unhealthy dietary habits of adding other ingredients such as sugar and spices in amount more than needed. Unmarried and fresh year students with high academic grades were associated with higher coffee consumption. The main determinants of coffee consumption among university students were high BMI and increased family income level. Continued awareness and basic knowledge, along with understanding the importance of reading food labels, should be provided to young generations. The university students must be cautioned to limit excessive coffee consumption and maintain healthy dietary habits. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=academic%20performance" title="academic performance">academic performance</a>, <a href="https://publications.waset.org/abstracts/search?q=BMI" title=" BMI"> BMI</a>, <a href="https://publications.waset.org/abstracts/search?q=coffee" title=" coffee"> coffee</a>, <a href="https://publications.waset.org/abstracts/search?q=health%20awareness" title=" health awareness"> health awareness</a> </p> <a href="https://publications.waset.org/abstracts/141197/coffee-consumption-predictors-prevalence-awareness-and-trend-among-saudi-university-students" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/141197.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">197</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">281</span> Evaluation of Water-Soluble Ionic Liquids Based on Quaternized Hyperbranched Polyamidoamine and Amino Acids for Chemical Enhanced Oil Recovery</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Rasha%20Hosny">Rasha Hosny</a>, <a href="https://publications.waset.org/abstracts/search?q=Ahmed%20Zahran"> Ahmed Zahran</a>, <a href="https://publications.waset.org/abstracts/search?q=Mahmoud%20Ramzi"> Mahmoud Ramzi</a>, <a href="https://publications.waset.org/abstracts/search?q=Fatma%20Mahmoud%20Abdelhafiz"> Fatma Mahmoud Abdelhafiz</a>, <a href="https://publications.waset.org/abstracts/search?q=Ammona%20S.%20Mohamed"> Ammona S.

In this study, two amino acid ionic liquids (AAILs) were prepared from quaternized hyperbranched polyamidoamine PAMAM (G0.5 C12) and amino acids (Cysteine and Lysine). The chemical structures of the prepared AAILs were verified by using FTIR and 1H-NMR spectra. These AAILs were tested for solubility, thermal stability, and surface activity in the presence of Egyptian medium crude oils under different PVT parameters after being diluted in several brine solutions of various salt compositions at 10% (w/w) salinity. The measurements reveal that the produced AAILs have good solubility and thermal stability. The effect of different concentrations of AAILs (0.1-5%) and salinity (20000-70000 ppm) on Interfacial tension (IFT) were studied. To test the efficacy of (AAILs) for a CEOR, numerous flooding experiments were carried out in samples of sandstone rock. Rock wettability is important for sandstone rocks, so conduct wettability alteration by contact angle (CA) of (30-55) and IFT of (7-13). The additional oil recovery was largely influenced by ionic liquid concentration, which may be changed by dilution with the formation and injected brines. This research has demonstrated that EOR techniques led to a recovery wt. (22-45%). <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=amino%20acid%20ionic%20liquids" title="amino acid ionic liquids">amino acid ionic
