The quality of services is always considered as the main aspect that attracts the customers’ attention and helps the airports to develop their services and operations. King Khalid International Airport is considered as the gateway of the Kingdom of Saudi Arabia. Therefore, the aim of this paper was to identify the quality service in the departure area at in King Khalid Airport. The SERVQUAL questionnaire was distributed among the passengers in King Khalid International Airport and the respondents have reached to 500 passengers. The results that are obtained from the SERVQUAL questionnaire showed that the quality of airport’s services is low. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=service%20quality" title="service quality">service quality</a>, <a href="https://publications.waset.org/abstracts/search?q=SERVQUAL%20methodology" title=" SERVQUAL methodology"> SERVQUAL methodology</a>, <a href="https://publications.waset.org/abstracts/search?q=King%20Khalid%20International%20Airport%20%28KKIA%29" title=" King Khalid International Airport (KKIA)"> King Khalid International Airport (KKIA)</a>, <a href="https://publications.waset.org/abstracts/search?q=customers%E2%80%99%20satisfaction" title=" customers’ satisfaction"> customers’ satisfaction</a> </p> <a href="https://publications.waset.org/abstracts/9133/measuring-quality-of-service-in-king-khalid-international-airport" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/9133.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">802</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">338</span> A New Source on Ottoman Self-Narratives: Kulakzade Mahmud Pasha’s Dream Diary</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Semra%20%C3%87%C3%B6rek%C3%A7i%CC%87">Semra Çörekçi̇</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this study, a new source on Ottoman Self-narratives, Kulakzâde Mahmud Paşa’s Düşname (Dreambook), will be introduced to illustrate how dreams can provide a ground for historical analysis. The manuscript looks like a private notebook of an Ottoman official, Mahmud Pasha, who lived and operated in Rumelia in the early eighteenth century. It provides insight into the ordinary and daily concerns of a bureaucrat who had the knowledge and tools to record them in writing. On the one side of the notebook, Mahmud Pasha recorded his travels and appointments in 1730-1731. He wrote places that he reached and stayed every day. On the reverse side, the same author kept a record of his dreams and named that part of his notebook, Düşname. He recorded his dreams on a daily basis in writing and therefore they were well-preserved in a dream diary. This study aims at drawing the social, cultural and psychic life of an early modern Ottoman bureaucrat. It will uncover the ways and means whereby he interpreted his environment, as well as how he made meaning of his dreams considering the social milieu and historical context within which he lived. The first part will focus on 'official dreams' uncovering how his official life and ambitions coincide with his spiritual life. Related to this, connection between anxiety and dream narratives will be evaluated as dreams in which the mundane concerns of securing a post occupied the most central place in the construction of his narrative. A further point will be made by questioning Mahmud Pasha’s possible Sufi connections and his familiarity with the tradition of dream interpretation. Also, considering Mahmud Pasha’s inclusion of other’s dreams in his Düşnâme, the issue of dream-telling will be questioned in order to reveal how dreams were interconnected and how they created a space for social gathering. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ottoman%20self-narratives" title="Ottoman self-narratives">Ottoman self-narratives</a>, <a href="https://publications.waset.org/abstracts/search?q=dreams" title=" dreams"> dreams</a>, <a href="https://publications.waset.org/abstracts/search?q=diary" title=" diary"> diary</a>, <a href="https://publications.waset.org/abstracts/search?q=Ottoman%20cultural%20history" title=" Ottoman cultural history"> Ottoman cultural history</a> </p> <a href="https://publications.waset.org/abstracts/71422/a-new-source-on-ottoman-self-narratives-kulakzade-mahmud-pashas-dream-diary" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/71422.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">251</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">337</span> The Impact of Indigenous Architecture and the Origin of Tomb Architecture in Indian Sub-Continent: A Case Study of the Tombs of Muhmmad B.

Toward this end, positive affect and negative affect of 103 adult indigenous persons were measured. Analysis of data in multiple regressions demonstrated that both gender and marital status are significantly associated with positive affect (Gender: β=.318, p < .001; Marital status: β=.201, p < .05), but not with negative affect. Results indicated that the indigenous males have 0.32 standard deviations increased positive affect as compared to the indigenous females and that married individuals have 0.20 standard deviations increased positive affect as compared to their unmarried counterparts. These findings advance our understanding that gender and marital status inequalities in the experience of emotion are not specific to the mainstream society; rather it is a generalized picture of all societies. In general, men possess more positive affect than females; married persons possess more positive affect than the unmarried persons. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=positive%20affect" title="positive affect">positive affect</a>, <a href="https://publications.waset.org/abstracts/search?q=negative%20affect" title=" negative affect"> negative affect</a>, <a href="https://publications.waset.org/abstracts/search?q=ethnic%20minority" title=" ethnic minority"> ethnic minority</a>, <a href="https://publications.waset.org/abstracts/search?q=gender" title=" gender"> gender</a>, <a href="https://publications.waset.org/abstracts/search?q=marital%20status" title=" marital status"> marital status</a> </p> <a href="https://publications.waset.org/abstracts/5538/the-affect-of-ethnic-minority-people-a-prediction-by-gender-and-marital-status" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/5538.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">448</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">334</span> Performance Analysis of Different PSK Scheme on Receiver Sensitivity and Round Trip Distance for Chipless RFID System for UWB with Rayleigh Fading Channels in Outdoor NLOS Environment</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Khalid%20Mahmud">Khalid Mahmud</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this paper, an analytic approach is presented to evaluate the Bit Error Rate (BER) and round trip distance for a UWB chipless RFID system using diversity technique at the reader receiver using different modulation technique. The analysis is carried out with multiresonator based chipless RFID tags using frequency range from 3 GHz − 6 GHz and bandwidth of 500 M Hz in outdoor non-line-of-sight (NLOS) environment. SISO configuration is used to communicate from the reader to the tag and SIMO configuration is used do vice versa. Maximal Ratio Combining (MRC) technique is used in the reader. MPSK, DQPSK, DBPSK, BPSK, QPSK and DMPSK modulation techniques are considered with coherent demodulation to evaluate the BER performance. From the numerical analysis of the results, it is found that at a given BER maximum possible round trip distance can be achieved using DMPSK modulation technique. In addition, it has been proved that, while using DMPSK modulation technique, the application of diversity has very little effect on the overall improvement in reader receiver sensitivity and achievable distance. Finally the method not only proves to be a very good way for tag detection in case of a chipless RFID system but also gives a clear insight regarding the interrelationship between BER, read range, reader received power, number of receiving antenna in outdoor NLOS environment. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=EGC" title="EGC">EGC</a>, <a href="https://publications.waset.org/abstracts/search?q=MRC" title=" MRC"> MRC</a>, <a href="https://publications.waset.org/abstracts/search?q=BER" title=" BER"> BER</a>, <a href="https://publications.waset.org/abstracts/search?q=read%20range" title=" read range"> read range</a>, <a href="https://publications.waset.org/abstracts/search?q=diversity" title=" diversity"> diversity</a> </p> <a href="https://publications.waset.org/abstracts/39438/performance-analysis-of-different-psk-scheme-on-receiver-sensitivity-and-round-trip-distance-for-chipless-rfid-system-for-uwb-with-rayleigh-fading-channels-in-outdoor-nlos-environment" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/39438.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">350</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">333</span> A Hybrid Genetic Algorithm for Assembly Line Balancing In Automotive Sector</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Qazi%20Salman%20Khalid">Qazi Salman Khalid</a>, <a href="https://publications.waset.org/abstracts/search?q=Muhammad%20Khalid"> Muhammad Khalid</a>, <a href="https://publications.waset.org/abstracts/search?q=Shahid%20Maqsood"> Shahid Maqsood</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper presents a solution for optimizing the cycle time in an assembly line with human-robot collaboration and diverse operators.

Although the internet is fully observed in Saudi Arabia, young people may be vulnerable to problematic internet use, possibly leading to addiction. Aim of study: To explore the magnitude of internet addiction (IA) among medical students associated risk factors and its impact on students' academic achievement. Subjects and Methods: A cross sectional study was conducted in 2014 on 571 medical students (293 males and 278 females) at the College of Medicine, King Khalid University, Abha, Saudi Arabia. Data Collection was done through using the Arabic version of the Compulsive Internet Use Scale and a checklist of demographic characteristics. Results: Age of participants ranged from 19 to 26 years (Mean+SD: 21.9+1.5 years). Internet access was available to 97.4% of students at home and to 80.2% of students at their mobile phones. The most frequently accessed websites by medical students were the social media (90.7%), scientific website (50.4%) and the news websites (31.3%). IA was mild in 47.8% of medical students while 5.8% had moderate IA. None of the students had severe IA. Prevalence of IA was significantly higher among female medical students (p=0.002), availability of internet at home (p=0.022), and availability of internet at the students' mobile phone (p=0.041). The mean General Point Average (GPA) was highest among students with mild IA (4.0+0.6), compared with 3.6+0.6 among those with moderate addiction, and 3.9+0.6 among those who did not show IA. Differences in mean GPA according to grade of IA were statistically significant ((P=0.001). Conclusions: Prevalence of IA is high among medical students in Saudi Arabia. Risk factors for IA include female gender, availability of internet at home or at the mobile phone. IA has a significant impact on students' GPA. Periodic screening of medical students for IA and raising their awareness toward the possible risk of IA are recommended. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=internet%20addiction" title="internet addiction">internet addiction</a>, <a href="https://publications.waset.org/abstracts/search?q=medical%20students" title=" medical students"> medical students</a>, <a href="https://publications.waset.org/abstracts/search?q=risk%20factors" title=" risk factors"> risk factors</a>, <a href="https://publications.waset.org/abstracts/search?q=Saudi%20Arabia" title=" Saudi Arabia"> Saudi Arabia</a> </p> <a href="https://publications.waset.org/abstracts/37906/screening-for-internet-addiction-among-medical-students-in-a-saudi-community" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/37906.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">529</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">329</span> Public Administrators, Code of Conduct and the Nigerian Society</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mahmud%20Adam">Mahmud Adam</a>, <a href="https://publications.waset.org/abstracts/search?q=Inuwa%20Abdu%20Ibrahim"> Inuwa Abdu Ibrahim</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The issue of ethics and values of public office holders in Nigerian has been and still is a matter of great mystery.

Methods: The study included 800 T2DM patients (400 metformin responders and 400 metformin non-responders) along with 400 ethnically matched healthy individuals. The genotypes were determined by allele-specific polymerase chain reaction. <em>In-silico</em> analysis was done to confirm the effect of the two SNPs on the structure of genes. Association was statistically determined using SPSS software. Results: Minor allele frequency for rs77474263 and rs77630697 was 0.13 and 0.12. For <em>SLC47A1 </em>rs77474263 the homozygotes of one mutant allele ‘T’ (CT) of rs77474263 variant were fewer in metformin responders than metformin non-responders (29.2% vs. 35.5 %). Likewise, the efficacy was further reduced (7.2% vs. 4.0 %) in homozygotes of two copies of ‘T’ allele (TT). Remarkably, T2DM cases with two copies of allele ‘C’ (CC) had 2.11 times more probability to respond towards metformin monotherapy. For <em>SLC47A1 </em>rs77630697 the homozygotes of one mutant allele ‘A’ (GA) of rs77630697 variant were fewer in metformin responders than metformin non-responders (33.5% vs. 43.0 %). Likewise, the efficacy was further reduced (8.5% vs. 4.5%) in homozygotes of two copies of ‘A’ allele (AA). Remarkably, T2DM cases with two copies of allele ‘G’ (GG) had 2.41 times more probability to respond towards metformin monotherapy. <em>In-silico</em> analysis revealed that these two variants affect the structure and stability of their corresponding proteins. Conclusion: The present data suggest that <em>SLC47A1 </em>Leu125Phe (rs77474263) and Gly64Asp (rs77630697) polymorphisms were associated with the therapeutic response of metformin in T2DM patients of Pakistan. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=diabetes" title="diabetes">diabetes</a>, <a href="https://publications.waset.org/abstracts/search?q=T2DM" title=" T2DM"> T2DM</a>, <a href="https://publications.waset.org/abstracts/search?q=SLC47A1" title=" SLC47A1"> SLC47A1</a>, <a href="https://publications.waset.org/abstracts/search?q=Pakistan" title=" Pakistan"> Pakistan</a>, <a href="https://publications.waset.org/abstracts/search?q=polymorphism" title=" polymorphism"> polymorphism</a> </p> <a href="https://publications.waset.org/abstracts/105468/genotypic-and-allelic-distribution-of-polymorphic-variants-of-gene-slc47a1-leu125phe-rs77474263-and-gly64asp-rs77630697-and-their-association-to-the-clinical-response-to-metformin-in-adult-pakistani-t2dm-patients" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/105468.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">159</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">326</span> Prevalence of Polypharmacy in Elderly Cardiac Patients at King Fahad Cardiac Center (KFCC) in King Khalid University Hospital (KKUH), Riyadh, Saudi Arabia</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mohamed%20N.%20Al-Arifi">Mohamed N.

Extraction (variables time, temperature and amplitude) was optimized by using response surface methodology (RSM) conducted by Box Behnken Design (BBD). The effect of time, temperature and amplitude were studied at three levels. It was observed that time and temperature exerted more impact on extraction efficiency as compared to amplitude. The highest yield of total dietary fiber (TDF), soluble dietary fiber (SDF) and In-soluble dietary fiber (IDF) fractions were observed under ultrasound processing for 20 min at 40 ◦C with 80% amplitude. Characterization of extracted dietary fiber showed that it had better crystallinity, thermal properties and good fibrous structure. It also showed better functional properties as compared to traditionally extracted dietary fiber. Furthermore, dietary fibers from oats may offer high-value utilization and the expansion of comprehensive utilization in functional food and nutraceutical development. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=extraction" title="extraction">extraction</a>, <a href="https://publications.waset.org/abstracts/search?q=ultrasonication" title=" ultrasonication"> ultrasonication</a>, <a href="https://publications.waset.org/abstracts/search?q=response%20surface%20methodology" title=" response surface methodology"> response surface methodology</a>, <a href="https://publications.waset.org/abstracts/search?q=box%20behnken%20design" title=" box behnken design"> box behnken design</a> </p> <a href="https://publications.waset.org/abstracts/187067/optimization-of-ultrasound-assisted-extraction-and-characterization-of-functional-properties-of-dietary-fiber-from-oat-cultivar-s2000" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/187067.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">50</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">324</span> Applying Intelligent Material in Food Packaging</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Kasra%20Ghaemi">Kasra Ghaemi</a>, <a href="https://publications.waset.org/abstracts/search?q=Syeda%20Tasnim"> Syeda Tasnim</a>, <a href="https://publications.waset.org/abstracts/search?q=Shohel%20Mahmud"> Shohel Mahmud</a> </p> <p class="card-text"><strong>Abstract:</strong></p> One of the main issues affecting the quality and shelf life of food products is temperature fluctuation during transportation and storage.

For all cases, a trucut biopsy, lumpectomy, or modified radical mastectomy was available for histopathologic diagnosis, while 105/140 (75%) had, as well, preoperative fine needle aspirates (FNA). Results: 49 cases out of 140 (35%) breast lesions were carcinomas: 44/49 (89.75%) was invasive ductal, 2/49(4.1%) invasive lobular carcinomas, 1/49(2.05%) intracystic low grade papillary carcinoma and 2/49 (4.1%) ductal carcinoma in situ (DCIS). Mean age for malignant cases was 45.06 (+/-10.58): 32.6% were below the age of 40 and 30.6 below 50 years, 18.3% below 60 and 16.3% below 70 years. For the benign group, mean age was 32.52 (+/10.5) years. Benign lesions were in order of frequency: 34 fibroadenomas, 14 fibrocystic disease, 12 chronic mastitis, five granulomatous mastitis, three intraductal papillomas, and three benign phyllodes tumor. Tubular adenoma, lipoma, skin nevus, pilomatrixoma, and breast reduction specimens constituted the remaining specimens. Conclusion: Breast lesions are common in our series and invasive carcinoma accounts for more than 1/3<sup>rd</sup> of the lumps, with 63.2% incidence in pre-menopausal ladies, below the age of 50 years. FNA as a non-invasive procedure, proved to be an effective tool in diagnosing both benign and malignant/suspicious breast lumps and should continue to be used as a first assessment line of palpable breast masses. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=age%20incidence" title="age incidence">age incidence</a>, <a href="https://publications.waset.org/abstracts/search?q=breast%20carcinoma" title=" breast carcinoma"> breast carcinoma</a>, <a href="https://publications.waset.org/abstracts/search?q=fine%20needle%20aspiration" title=" fine needle aspiration"> fine needle aspiration</a>, <a href="https://publications.waset.org/abstracts/search?q=hail%20region" title=" hail region"> hail region</a> </p> <a href="https://publications.waset.org/abstracts/72605/patterns-of-malignant-and-benign-breast-lesions-in-hail-region-a-retrospective-study-at-king-khalid-hospital" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/72605.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">280</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">321</span> Administrative Reform and the Changing Nature of Higher Education: A Lesson from Indonesian Higher Education Reforms</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Nurdiana%20Gaus">Nurdiana Gaus</a>, <a href="https://publications.waset.org/abstracts/search?q=Mahmud%20Tang"> Mahmud Tang</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper analyses changes being experienced by academics in Indonesian state university systems as a result of government-driven policy and the impacts of these changes on academics work and organisations.

The first sultan of this century, Mahmud II (1808-1839), was the architect of Ottoman modernization and fundamental changes. The most radical of these was abolishing the Janissary corps and the traditional Ottoman military band, Mehteran. Mahmud II introduced modernized military corps as well as western style royal and military music. Mahmut II invited the Italian composer Giuseppe Donizetti to establish a modern military band for the new army and to compose the Sultan’s royal anthem. In 1828, Donizetti composed the first western-style Ottoman anthem, Mahmudiyye anthem. During the 19th and early 20th century, four other western style Ottoman anthems (Aziziyye, Mecidiyye, Hamidiyye, and Resadiyye) were composed but the last anthem adopted in the reign of Mehmet VI (r. 1918-1922) was again Mahmudiyye anthem. This paper aims to analyze the Mahmudiyye anthem composed as royal anthem in 1828 but adopted as national anthem in 1918. Research questions of this paper are as follows: What were the characteristics of the Mahmudiyye anthem making it the best choice of the last sultan for the last national anthem? Are there specific reasons of the last sultan to adopt Mahmudiyye anthem or not to adopt any of the other four anthems? The musical characteristics of the anthem are analyzed based on the Cerulo’s empirical research. Cerulo examined the musical structures of 124 western style anthems from 150 countries in the 1580-1976 period. Cerulo’s research categorizes musical codes of the anthems as basic and embellished related with the level of sociopolitical control. Musical analysis of the anthem indicates that the basic musical code of the anthem implies a high level of socio-political control during the reign of both Mahmut II and Mehmet VI. Historical analysis of each sultans’ reign shows that both sultans were autocratic. Mahmut II designed authoritarian government policies to suppress possible reactions against his reforms. On the other hand, authoritarian policies of Mehmet VI are related with the domestic and international political conditions following the World War I. Historical analysis of the research questions show that compared to the other western style Ottoman anthems, Mahmudiyye anthem remained the only neutral anthem symbolizing modernization and westernization of the empire. Other anthems were all the symbols of failed ideologies such as Ottomanism, pan-Islamism, and pan-Turkism. In the early 20th century, there were a few common things remained among the diverse communities of the Ottoman Empire: The land they shared as homeland and the idea of modernization to save the homeland. For this reason, the last sultan Mehmet VI adopted Mahmudiyye anthem as the memory of a unified empire under the rule of a powerful and modernist sultan. The last sultan’s reign lasted just for four years, and the Ottoman Empire disintegrated in 1922, but his adaptation of the Mahmudiyye anthem indicates his unifying policies, his attitudes to save the empire and the caliphate. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mahmudiyye%20anthem" title="Mahmudiyye anthem">Mahmudiyye anthem</a>, <a href="https://publications.waset.org/abstracts/search?q=musical%20code" title=" musical code"> musical code</a>, <a href="https://publications.waset.org/abstracts/search?q=national%20anthem" title=" national anthem"> national anthem</a>, <a href="https://publications.waset.org/abstracts/search?q=Ottoman%20Empire" title=" Ottoman Empire"> Ottoman Empire</a>, <a href="https://publications.waset.org/abstracts/search?q=royal%20anthem" title=" royal anthem"> royal anthem</a> </p> <a href="https://publications.waset.org/abstracts/101282/the-last-national-anthem-of-the-ottoman-empire-musical-code-sociopolitical-control-and-historical-realities" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/101282.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">204</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">318</span> Image Segmentation Using 2-D Histogram in RGB Color Space in Digital Libraries </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=El%20Asnaoui%20Khalid">El Asnaoui Khalid</a>, <a href="https://publications.waset.org/abstracts/search?q=Aksasse%20Brahim"> Aksasse Brahim</a>, <a href="https://publications.waset.org/abstracts/search?q=Ouanan%20Mohammed"> Ouanan Mohammed </a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper presents an unsupervised color image segmentation method.

Body-contouring surgery offers a solution to this problem; however, there is scarce literature on the psychological and social effects of these surgeries. This study was conducted to assess the psychosocial impact of body-contouring surgery on patients after weight loss. Methodology: In this cross-sectional study, a specifically designed questionnaire was administered to forty three patients whom have undergone body-contouring surgery. All included patients had lost no less than 20 Kg before body-contouring surgery, and were interviewed at least 6 months after surgery. The twenty-question interviewer based questionnaire was used to assess the psychosocial status of the patients before and after undergoing body-contouring surgery. The questionnaire assessed the quality of life (social life, job performance and sexual activity), presence of symptoms of depression and overall satisfaction. Data was analyzed as paired variables in SPSS using McNemar’s test. Results: Among the 43 participants, 19 (44.2%) have undergone mammoplasty, 12 (27.9%) have undergone abdominoplasty and the remainder of the patients have undergone other various procedures including brachioplasty, thigh lifts and nick liposuction. The mean age of patients was 34 +/- 10, the sample included 24 (55.8%) females and 19 (44.2%) males. The patients’ quality of life significantly improved in the following areas; social life (P<0.001), job performance (P<0.002) and sexual activity (P<0.001). Moreover, 17 (39.5%) patients suffered symptoms of depression before body-contouring surgery; however, only 1 (2.3%) patient suffered symptoms of depression after surgery. Overall satisfaction rate was found to be 62.8%; with mammoplasty being the highest satisfaction rate procedure (66.6 %). Conclusion: Body-contouring surgery after weight loss has shown to improve the psychological and social aspects in patients. These findings have been found to be consistent with the majority of relevant published studies, further increasing reliability of our study. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=abdominoplasty" title="abdominoplasty">abdominoplasty</a>, <a href="https://publications.waset.org/abstracts/search?q=body-contouring" title=" body-contouring"> body-contouring</a>, <a href="https://publications.waset.org/abstracts/search?q=mammoplasty" title=" mammoplasty"> mammoplasty</a>, <a href="https://publications.waset.org/abstracts/search?q=psychosocial" title=" psychosocial"> psychosocial</a> </p> <a href="https://publications.waset.org/abstracts/48462/psychosocial-effect-of-body-contouring-surgery-on-patients-after-weight-loss" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/48462.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">285</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">316</span> A Study of Permission-Based Malware Detection Using Machine Learning</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ratun%20Rahman">Ratun Rahman</a>, <a href="https://publications.waset.org/abstracts/search?q=Rafid%20Islam"> Rafid Islam</a>, <a href="https://publications.waset.org/abstracts/search?q=Akin%20Ahmed"> Akin Ahmed</a>, <a href="https://publications.waset.org/abstracts/search?q=Kamrul%20Hasan"> Kamrul Hasan</a>, <a href="https://publications.waset.org/abstracts/search?q=Hasan%20Mahmud"> Hasan Mahmud</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Malware is becoming more prevalent, and several threat categories have risen dramatically in recent years.

The antenna is made up of a diamond shape radiating patch, partial ground plane, and three asterisk-shaped parasitic elements. The parasitic elements are positioned above the ground plane to enhance the bandwidth and gain. The proposed antenna has a compact dimension of 30 x 25 x 1.6 mm3 and achieves an overall bandwidth (S11<-10dB) is 5.8 GHz from 2.7 GHz to 8.5 GHz. The antenna attains more than 4 dBi realized the gain and 80% efficiency over the bandwidth with omnidirectional radiation pattern. The design and simulation of the proposed antenna are performed in Computer Simulation Technology (CST) Microwave Studio. The observation during the analysis of the simulated data reveals that the proposed antenna is suitable for Ultra wide-band (UWB) applications where high gain is required. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=diamond-shaped%20antenna" title="diamond-shaped antenna">diamond-shaped antenna</a>, <a href="https://publications.waset.org/abstracts/search?q=microstrip%20antenna" title=" microstrip antenna"> microstrip antenna</a>, <a href="https://publications.waset.org/abstracts/search?q=parasitic%20resonator" title=" parasitic resonator"> parasitic resonator</a>, <a href="https://publications.waset.org/abstracts/search?q=UWB%20applications" title=" UWB applications"> UWB applications</a> </p> <a href="https://publications.waset.org/abstracts/91476/a-parasitic-resonator-based-diamond-shape-microstrip-antenna-for-ultra-wide-band-applications" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/91476.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">223</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">314</span> Financial Ethics: A Review of 2010 Flash Crash</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Omer%20Farooq">Omer Farooq</a>, <a href="https://publications.waset.org/abstracts/search?q=Salman%20Ahmed%20Khan"> Salman Ahmed Khan</a>, <a href="https://publications.waset.org/abstracts/search?q=Sadaf%20Khalid"> Sadaf Khalid</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Modern day stock markets have almost entirely became automated.

Thus, understanding the epidemiology of this parasite in animal populations is vital to controlling its transmission to humans as well as to other animal groups. Objectives: This systematic review and meta-analysis aim to summarise and analyse reports of T. gondii infection in animal species residing in the Arabian Peninsula. Methods: It was conducted in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA), with relevant studies being retrieved from MEDLINE/PubMed, Scopus, Cochrane Library, Google Scholar and ScienceDirect. All articles published in Arabic or English languages between January 2000 and December 2020 were screened for eligibility. The random effects model was used to calculate the pooled prevalence of T. gondii infection in different animal populations which were found to harbour this infection. The critical appraisal tool for prevalence studies designed by the Joanna Briggs Institute (JBI) was used to assess the risk of bias in all included studies. Results: A total of 15 studies were retrieved, reporting prevalence estimates from 4 countries in this region and in 13 animal species. A quantitative meta-analysis estimated a pooled prevalence of 43% in felids [95% confidence interval (CI) = 23-64%, I2 index = 100%], 48% in sheep (95% CI = 27-70%, I2 = 99%) and 21% in camels (95% CI = 7-35%, I2 = 99%). Evidence of possible publication bias was found in both felids and sheep. Conclusions: This meta-analysis estimates a high prevalence of T. gondii infection in animal species that are of high economic and cultural importance to countries of this region. Hence, these findings provide valuable insight to public health authorities as well as economic and animal resources advisors in countries of the Arabian Peninsula. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Arabian%20Peninsula" title="Arabian Peninsula">Arabian Peninsula</a>, <a href="https://publications.waset.org/abstracts/search?q=toxoplasma%20gondii" title=" toxoplasma gondii"> toxoplasma gondii</a>, <a href="https://publications.waset.org/abstracts/search?q=animals%3B%20meta-analysis" title=" animals; meta-analysis"> animals; meta-analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=toxoplasmosis" title=" toxoplasmosis"> toxoplasmosis</a> </p> <a href="https://publications.waset.org/abstracts/165882/epidemiology-of-toxoplasma-gondii-infection-in-animals-of-the-arabian-peninsula-a-systematic-review-and-meta-analysis" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/165882.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">84</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">312</span> Improvement of the Aerodynamic Behaviour of a Land Rover Discovery 4 in Turbulent Flow Using Computational Fluid Dynamics (CFD)</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ahmed%20Al-Saadi">Ahmed Al-Saadi</a>, <a href="https://publications.waset.org/abstracts/search?q=Ali%20Hassanpour"> Ali Hassanpour</a>, <a href="https://publications.waset.org/abstracts/search?q=Tariq%20Mahmud"> Tariq Mahmud</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The main objective of this study is to investigate ways to reduce the aerodynamic drag coefficient and to increase the stability of the full-size Sport Utility Vehicle using three-dimensional Computational Fluid Dynamics (CFD) simulation. The baseline model in the simulation was the Land Rover Discovery 4. Many aerodynamic devices and external design modifications were used in this study. These reduction aerodynamic techniques were tested individually or in combination to get the best design. All new models have the same capacity and comfort of the baseline model. Uniform freestream velocity of the air at inlet ranging from 28 m/s to 40 m/s was used. ANSYS Fluent software (version 16.0) was used to simulate all models. The drag coefficient obtained from the ANSYS Fluent for the baseline model was validated with experimental data. It is found that the use of modern aerodynamic add-on devices and modifications has a significant effect in reducing the aerodynamic drag coefficient. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=aerodynamics" title="aerodynamics">aerodynamics</a>, <a href="https://publications.waset.org/abstracts/search?q=RANS" title=" RANS"> RANS</a>, <a href="https://publications.waset.org/abstracts/search?q=sport%20utility%20vehicle" title=" sport utility vehicle"> sport utility vehicle</a>, <a href="https://publications.waset.org/abstracts/search?q=turbulent%20flow" title=" turbulent flow"> turbulent flow</a> </p> <a href="https://publications.waset.org/abstracts/63731/improvement-of-the-aerodynamic-behaviour-of-a-land-rover-discovery-4-in-turbulent-flow-using-computational-fluid-dynamics-cfd" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/63731.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">316</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">311</span> Paradigm Shift of Leadership: Leaders in Information Technology</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mustafa%20Hyder">Mustafa Hyder</a>, <a href="https://publications.waset.org/abstracts/search?q=Khalid%20Mahmood%20Iraqi"> Khalid Mahmood Iraqi</a>, <a href="https://publications.waset.org/abstracts/search?q=Sameen%20Mustafa"> Sameen Mustafa</a> </p> <p class="card-text"><strong>Abstract:</strong></p> They say if the leader limps, all the others will start limping too.

The efficiency and the pressure drop of the C-H mixer along with two known SAR passive mixers named Chain and Tear-drop were investigated numerically at Reynolds numbers up to 100, taking into account species transport. At the same time experimental tests of the Chain and Tear-drop mixers were carried out at low Reynolds number, in the 0.1≤Re≤4.2 range. Numerical and experimental results coincide considerably, which validate the numerical simulation approach. Results show that mixing efficiency of the Tear-drop mixer is good except at the middle range of Reynolds number but pressure drop is too high; conversely the Chain mixer has moderate pressure drop but relatively low mixing efficiency at low and middle Re numbers. Whereas, the C-H mixer gives excellent mixing efficiency at all range of Re numbers. In addition, the C-H mixer shows respectively about 3 and 2 times lower pressure drop than the Tear-drop mixer and the Chain mixer. <p class="card-text"><strong>Keywords:</strong> <a
