Technology advancements have enabled the development of it to do many excellent jobs as reconnaissance, surveillance, battle fighters, and communications relays. Simulating a small unmanned aerial vehicle (SUAV) dynamics and analyzing its behavior at the preflight stage is too important and more efficient. The first step in the UAV design is the mathematical modeling of the nonlinear equations of motion. In this paper, a survey with a standard method to obtain the full non-linear equations of motion is utilized,and then the linearization of the equations according to a steady state flight condition (trimming) is derived. This modeling technique is applied to an Ultrastick-25e fixed wing UAV to obtain the valued linear longitudinal and lateral models. At the end, the model is checked by matching between the behavior of the states of the non-linear UAV and the resulted linear model with doublet at the control surfaces. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=UAV" title="UAV">UAV</a>, <a href="https://publications.waset.org/abstracts/search?q=equations%20of%20motion" title=" equations of motion"> equations of motion</a>, <a href="https://publications.waset.org/abstracts/search?q=modeling" title=" modeling"> modeling</a>, <a href="https://publications.waset.org/abstracts/search?q=linearization" title=" linearization"> linearization</a> </p> <a href="https://publications.waset.org/abstracts/23317/modeling-of-a-small-unmanned-aerial-vehicle" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/23317.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">743</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">176</span> From Reform to Revolt: Bashar al-Assad and the Arab Tribes in Syria</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Haian%20Dukhan">Haian Dukhan</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The death of Hafez al-Assad and the ascension of his son, Bashar, to rule brought an end to the state-society dynamics that his father worked on for decades. Hafez al-Assad built an authoritarian state that rests on patronage networks that connected his regime to the society. During Bashar’s reign, these patronage relationships have been affected by the policies of privatization and liberalization. Privatization and liberalisation of the economy have created new economic and social players that transformed the populist nature of the authoritarian regime into a regime that is connected mainly with bourgeoisie and the upper class neglecting the rural tribal constituency that was a vital part of Hafez al-Assad’s authoritarian state. Drawing on different data gathered through interviews as well as written literature, this paper will explore the policies that Bashar al-Assad carried out towards the Arab tribes in the period extended from 2000 until 2010. The paper starts by outlining how Bashar al-Assad narrowed the coalition of his rule to depend mainly on his family, the city merchants excluding the lower and middle strata in the periphery. It will then trace the disintegration of the social contract between the regime and the Arab tribe as a result of the latter’s failure to deliver adequate development services in their regions. Losing the support of the tribes undermined the stability of the regime resulting in different clashes between the tribes themselves, the tribes and the Kurds, the tribes and the druze (a sect of Islam situated in Southern Syria), which will be investigated in detail in this paper. In similar policies adopted by his father who used the tribes as leverage against the Islamists and the Kurds, Bashar al-Assad’s regime encouragement of Syrian tribal youth to join the Iraqi insurgency against the Americans will be explored in detail. The regime’s tolerance of Iran missionary activities in the tribal regions and its accommodation of Islamists group’s activities in those regions have erased the regime’s secular foundation. This paper will argue that Bashar al-Assad’s policies towards the Arab tribes have chipped away the regime’s ideological pillars and threatened the longer-term cohesion of its social base which paved the way for the uprising to start in the tribal regions. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Syria" title="Syria">Syria</a>, <a href="https://publications.waset.org/abstracts/search?q=tribes" title=" tribes"> tribes</a>, <a href="https://publications.waset.org/abstracts/search?q=uprising" title=" uprising"> uprising</a>, <a href="https://publications.waset.org/abstracts/search?q=regime" title=" regime"> regime</a> </p> <a href="https://publications.waset.org/abstracts/36885/from-reform-to-revolt-bashar-al-assad-and-the-arab-tribes-in-syria" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/36885.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">377</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">175</span> Role of P53, KI67 and Cyclin a Immunohistochemical Assay in Predicting Wilms’ Tumor Mortality</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ahmed%20Atwa">Ahmed Atwa</a>, <a href="https://publications.waset.org/abstracts/search?q=Ashraf%20Hafez"> Ashraf Hafez</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohamed%20Abdelhameed"> Mohamed Abdelhameed</a>, <a href="https://publications.waset.org/abstracts/search?q=Adel%20Nabeeh"> Adel Nabeeh</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohamed%20Dawaba"> Mohamed Dawaba</a>, <a href="https://publications.waset.org/abstracts/search?q=Tamer%20Helmy"> Tamer Helmy</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Introduction and Objective: Tumour staging and grading do not usually reflect the future behavior of Wilms' tumor (WT) regarding mortality. Therefore, in this study, P53, Ki67 and cyclin A immunohistochemistry were used in a trial to predict WT cancer-specific survival (CSS). Methods: In this nonconcurrent cohort study, patients' archived data, including age at presentation, gender, history, clinical examination and radiological investigations, were retrieved then the patients were reviewed at the outpatient clinic of a tertiary care center by history-taking, clinical examination and radiological investigations to detect the oncological outcome. Cases that received preoperative chemotherapy or died due to causes other than WT were excluded. Formalin-fixed, paraffin-embedded specimens obtained from the previously preserved blocks at the pathology laboratory were taken on positively charged slides for IHC with p53, Ki67 and cyclin A. All specimens were examined by an experienced histopathologist devoted to the urological practice and blinded to the patient's clinical findings. P53 and cyclin A staining were scored as 0 (no nuclear staining),1 (<10% nuclear staining), 2 (10-50% nuclear staining) and 3 (>50% nuclear staining). Ki67 proliferation index (PI) was graded as low, borderline and high. Results: Of the 75 cases, 40 (53.3%) were males and 35 (46.7%) were females, and the median age was 36 months (2-216). With a mean follow-up of 78.6±31 months, cancer-specific mortality (CSM) occurred in 15 (20%) and 11 (14.7%) patients, respectively. Kaplan-Meier curve was used for survival analysis, and groups were compared using the Log-rank test. Multivariate logistic regression and Cox regression were not used because only one variable (cyclin A) had shown statistical significance (P=.02), whereas the other significant factor (residual tumor) had few cases. Conclusions: Cyclin A IHC should be considered as a marker for the prediction of WT CSS. Prospective studies with a larger sample size are needed. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=wilms%E2%80%99%20tumour" title="wilms’ tumour">wilms’ tumour</a>, <a href="https://publications.waset.org/abstracts/search?q=nephroblastoma" title=" nephroblastoma"> nephroblastoma</a>, <a href="https://publications.waset.org/abstracts/search?q=urology" title=" urology"> urology</a>, <a href="https://publications.waset.org/abstracts/search?q=survival" title=" survival"> survival</a> </p> <a href="https://publications.waset.org/abstracts/174047/role-of-p53-ki67-and-cyclin-a-immunohistochemical-assay-in-predicting-wilms-tumor-mortality" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/174047.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">67</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">174</span> Evaluation of the Predatory Mites' Manner against Root-Knot Nematode Using Water Agar Technique</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Abdelrady%20K.%20Nasr">Abdelrady K.

Moreover, the soil predatory mites (Protogamasellopsisdenticus (Nasr), Gaeolaelaps longus (Hafez, El-Badry and Nasr) and Cosmolaelapskeni(Hafez, El-Badry and Nasr) are one of the excellent agents for biocontrol, this study was designed to evaluate the predation of the root-knot nematode (M. incognita) using water agar technique. The water agar medium was used as an experimental medium to rear both the mentioned mites and egg masses; these media allowed observe the development and predacious manner. The present study revealed that the predatory mites successfully developed and reproduced their egg masses. The mean life cycle of the tested mites P. denticus, G. longus, and C.keni were 10.33, 12.00, and 9.77 days, respectively. The mean total life span of the female of P. denticus, G. longus, and C. keni on egg-mases of M. incognita were obtained 63.44, 77.55 and 70.11 days, respectively, and the mean total fecundity of predatory mites, P. denticus, G.longus, and C. keni on egg-mases nematode were observed 62.66, 31.61 and 11.83 eggs, respectively. The mean total number of eggs laid by female P. denticus was significantly higher than other predatory mites, G. longus and C. keni. According to the obtained results, the tested predacious mites can be applied to combat the spreading of M. incognita in the agriculture field as a safe and effective biological control. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=biological%20control" title="biological control">biological control</a>, <a href="https://publications.waset.org/abstracts/search?q=plant-parasitic%20nematodes" title=" plant-parasitic nematodes"> plant-parasitic nematodes</a>, <a href="https://publications.waset.org/abstracts/search?q=predaceous%20mites" title=" predaceous mites"> predaceous mites</a>, <a href="https://publications.waset.org/abstracts/search?q=water%20agar" title=" water agar"> water agar</a> </p> <a href="https://publications.waset.org/abstracts/174142/evaluation-of-the-predatory-mites-manner-against-root-knot-nematode-using-water-agar-technique" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/174142.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">79</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">173</span> Mining Big Data in Telecommunications Industry: Challenges, Techniques, and Revenue Opportunity</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Hoda%20A.%20Abdel%20Hafez">Hoda A.

Asian countries are more prone to the impact of this phenomenon, and Pakistan is the leading affected country. Last few years, governments all over the world have been trying to cater to this issue for the best entrust of their population, especially agriculture. Now the farmers in Pakistan are fully aware of the term “climate change” and are more concerned about its solutions. On the other hand, developed countries like the USA are setting a benchmark for developing countries in every sphere of life. Based on cultural and other variations, the research was carried out to identify the behavior of farmers regarding the same issue. Cross-sectional survey research was designed for an in-depth study of relevant research questions. Face-to-face interviews were conducted in Pakistan, while virtual and face-to-face interviews were conducted in the Indiana State of the USA. The results of the present study and the responses of farmers were very interesting. The common climate change mitigation strategies suggested by farmers of both countries were less use of motor vehicles (replacement with bicycles in the circle of 10 Km), less dependency on chemical fertilizers (increased use of Manure, Bio-fertilizer, Compost), and plantation of the tree. The difference of opinion was in less government interest, lack of farmers’ education, political instability (views of Pakistani farmers), awareness of local communities, self-satisfaction, and economic disparities (views of USA farmers). Based on the given evidence, it was recommended that there is a dire need to address the climate change issue all over the world without discrimination of race, color, region, or religion. Because it will affect not only agriculture but also the real effect will be on HUMANITY. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=climate%20change" title="climate change">climate change</a>, <a href="https://publications.waset.org/abstracts/search?q=mitigation%20strategies" title=" mitigation strategies"> mitigation strategies</a>, <a href="https://publications.waset.org/abstracts/search?q=forests" title=" forests"> forests</a>, <a href="https://publications.waset.org/abstracts/search?q=biodiversity" title=" biodiversity"> biodiversity</a> </p> <a href="https://publications.waset.org/abstracts/162155/comparative-analysis-of-climate-mitigation-strategies-adopted-by-farmers-of-pakistan-and-the-usa" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/162155.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">125</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">171</span> Combined Localization, Beamforming, and Interference Threshold Estimation in Underlay Cognitive System</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Omar%20Nasr">Omar Nasr</a>, <a href="https://publications.waset.org/abstracts/search?q=Yasser%20Naguib"> Yasser Naguib</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohamed%20Hafez"> Mohamed Hafez </a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper aims at providing an innovative solution for blind interference threshold estimation in an underlay cognitive network to be used in adaptive beamforming by secondary user Transmitter and Receiver.

The findings, derived from the analysis, show current classrooms have limited functional spaces, and concludes that AR application can be used in design classrooms to provide a variety of visuals and virtual objects that are required in conducting architecture projects in higher educational centers. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=design%20activity" title="design activity">design activity</a>, <a href="https://publications.waset.org/abstracts/search?q=space%20enhancement" title=" space enhancement"> space enhancement</a>, <a href="https://publications.waset.org/abstracts/search?q=design%20education" title=" design education"> design education</a>, <a href="https://publications.waset.org/abstracts/search?q=architectural%20design%20augmented%20reality" title=" architectural design augmented reality"> architectural design augmented reality</a> </p> <a href="https://publications.waset.org/abstracts/13284/development-of-adaptive-architecture-classrooms-through-the-application-of-augmented-reality-in-private-universities-of-malaysia" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/13284.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">446</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">169</span> Improving the Electrical Conductivity of Epoxy Coating Using Carbon Nanotube by Electrodeposition Method</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mahla%20Zabet">Mahla Zabet</a>, <a href="https://publications.waset.org/abstracts/search?q=Navid%20Zanganeh"> Navid Zanganeh</a>, <a href="https://publications.waset.org/abstracts/search?q=Hafez%20Balavi"> Hafez Balavi</a>, <a href="https://publications.waset.org/abstracts/search?q=Farbod%20Sharif"> Farbod Sharif</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Electrodeposition is a method for applying coatings with uniform thickness on complex objects. A conductive surface can be produced using the electrical current in this method. Carbon nanotubes are known to have high electrical conductivity and mechanical properties. In this report, NH2-multiwalled carbon nanotubes (MWCNTs) were used in epoxy resin with different weight percent. The weight percent of incorporated MWCNTS into the matrix was changed in the range of 0.6-3.6 wt% to obtain a series of electrocoatings. The electrocoats were then applied on steel substrates by a cathodic electrodeposition technique. Scanning electron microscopy (SEM) and optical microscopy were used to characterize the electrocoated films. The results illustrated the increase in conductivity by increasing of MWCNT load. However, at the percolation threshold, throwing power was dropped with increase in recoating ability. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=electrodeposition" title="electrodeposition">electrodeposition</a>, <a href="https://publications.waset.org/abstracts/search?q=carbon%20nanotube" title=" carbon nanotube"> carbon nanotube</a>, <a href="https://publications.waset.org/abstracts/search?q=electrical%20conductivity" title=" electrical conductivity"> electrical conductivity</a>, <a href="https://publications.waset.org/abstracts/search?q=throwing%20power" title=" throwing power"> throwing power</a> </p> <a href="https://publications.waset.org/abstracts/17061/improving-the-electrical-conductivity-of-epoxy-coating-using-carbon-nanotube-by-electrodeposition-method" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/17061.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">415</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">168</span> A Comparison between Modelled and Actual Thermal Performance of Load Bearing Rammed Earth Walls in Egypt</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=H.%20Hafez">H.

The objective of this paper is to outline how the thermal performance of rammed earth walls compares to conventional reinforced concrete skeleton and red brick in-fill walls. For this sake, the indoor temperature and relative humidity of a classroom built with rammed earth walls and a vaulted red brick roof in the area of Behbeit, Giza, Egypt were measured hourly over 6 months using smart sensors. These parameters for the rammed earth walls were later also compared against the values obtained using a 'DesignBuilder v5' model to verify the model assumptions. The thermal insulation of rammed earth walls was found to be 30% better than this of the redbrick infill, and the recorded data were found to be almost 90% similar to the modelled values. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=rammed%20earth" title="rammed earth">rammed earth</a>, <a href="https://publications.waset.org/abstracts/search?q=thermal%20insulation" title=" thermal insulation"> thermal insulation</a>, <a href="https://publications.waset.org/abstracts/search?q=indoor%20air%20quality" title=" indoor air quality"> indoor air quality</a>, <a href="https://publications.waset.org/abstracts/search?q=design%20builder" title=" design builder"> design builder</a> </p> <a href="https://publications.waset.org/abstracts/99687/a-comparison-between-modelled-and-actual-thermal-performance-of-load-bearing-rammed-earth-walls-in-egypt" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/99687.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">146</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">167</span> Reproductive Traits for Holstein Cattle </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ashraf%20M.%20Ward">Ashraf M.

The overall means and standard errors for AFC and CI were 39.4 ± 7.2 months and 487.5 ± 151.6 days respectively. The respective heritability estimates were 0.091 ± 0.05 and 0.044 ± 0.032, while the repeatability estimate for CI was 0.096 ± 0.001. The genetic trends for CI and AFC were -0.6 d/yr and -0.01 mo/yr respectively and were both significant (P < 0.001), indicating a decrease in mean breeding value over the study period. Phenotypic trends were -0.31 mo/yr and -0.35 d/yr for AFC and CI respectively though non-significant (P > 0.05). The low heritability for CI and AFC indicated that temporary environmental influences were much greater than genetic influences or permanent environmental influences on these traits. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Holstein" title="Holstein">Holstein</a>, <a href="https://publications.waset.org/abstracts/search?q=reproductive" title=" reproductive"> reproductive</a>, <a href="https://publications.waset.org/abstracts/search?q=genetic%20parameters" title=" genetic parameters"> genetic parameters</a>, <a href="https://publications.waset.org/abstracts/search?q=heritability" title=" heritability "> heritability </a> </p> <a href="https://publications.waset.org/abstracts/18509/reproductive-traits-for-holstein-cattle" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/18509.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">721</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">166</span> Dentofacial-Targeted Bullying: A Review</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mai%20Ashraf%20Talaat">Mai Ashraf Talaat</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Bullying is an aggressive behavior and a serious issue that should be addressed by everyone and should be avoided at all costs. It is very common among adolescents and schoolchildren and the effects can be devastating and long-lasting. Students are most commonly bullied about physical appearance, race, gender, disability, ethnicity, religion, and sexual orientation. Appearance-targeted bullying is a form of bullying that targets an aspect of a person's appearance, which includes facial and dental features. Deviation from accepted dentofacial aesthetics leads to elevated incidences of bullying in schoolchildren. The aim of this review article is to assess the prevalence of bullying due to dentofacial characteristics and evaluate the importance of dentofacial appearance on perceived social attractiveness based on multiple studies. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=dentofacial%20features" title="dentofacial features">dentofacial features</a>, <a href="https://publications.waset.org/abstracts/search?q=orthodontics" title=" orthodontics"> orthodontics</a>, <a href="https://publications.waset.org/abstracts/search?q=malocclusion" title=" malocclusion"> malocclusion</a>, <a href="https://publications.waset.org/abstracts/search?q=adolescents" title=" adolescents"> adolescents</a>, <a href="https://publications.waset.org/abstracts/search?q=bullying" title=" bullying"> bullying</a> </p> <a href="https://publications.waset.org/abstracts/166879/dentofacial-targeted-bullying-a-review" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/166879.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">79</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">165</span> The Effects of Integrating Knowledge Management and e-Learning: Productive Work and Learning Coverage</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ashraf%20Ibrahim%20Awad">Ashraf Ibrahim Awad</a> </p> <p class="card-text"><strong>Abstract:</strong></p> It is important to formulate suitable learning environments ca-pable to be customized according to value perceptions of the university. In this paper, light is shed on the concepts of integration between knowledge management (KM), and e-learning (EL) in the higher education sector of the economy in Abu Dhabi Emirate, United Arab Emirates (UAE). A discussion on and how KM and EL can be integrated and leveraged for effective education and training is presented. The results are derived from the literature and interviews with 16 of the academics in eight universities in the Emirate. The conclusion is that KM and EL have much to offer each other, but this is not yet reflected at the implementation level, and their boundaries are not always clear. Interviews have shown that both concepts perceived to be closely related and, responsibilities for these initiatives are practiced by different departments or units. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=knowledge%20management" title="knowledge management">knowledge management</a>, <a href="https://publications.waset.org/abstracts/search?q=e-learning" title=" e-learning"> e-learning</a>, <a href="https://publications.waset.org/abstracts/search?q=learning%20integration" title=" learning integration"> learning integration</a>, <a href="https://publications.waset.org/abstracts/search?q=universities" title=" universities"> universities</a>, <a href="https://publications.waset.org/abstracts/search?q=UAE" title=" UAE"> UAE</a> </p> <a href="https://publications.waset.org/abstracts/34904/the-effects-of-integrating-knowledge-management-and-e-learning-productive-work-and-learning-coverage" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/34904.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">507</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">164</span> Social Information Seeking: Studying the Effect of Question Type on Responses in Social Q&A Sites</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Arshia%20Ayoub">Arshia Ayoub</a>, <a href="https://publications.waset.org/abstracts/search?q=Zahid%20Ashraf%20Wani"> Zahid Ashraf Wani</a> </p> <p class="card-text"><strong>Abstract:</strong></p> With the introduction of online social Q&A sites, people are able to reach each other efficiently for information seeking and simultaneously creating social bonds.

To achieve sustainable supply chain, all three dimensions of sustainability should be considered. Unlike the economic and environmental aspects, social sustainability has been rarely given attention. The problem surrounding social sustainability and employees’ welfare in Egypt is complex and remains unsolved. The aim of this study is to qualitatively assess the current level of application of social sustainability in the retailing sector in Egypt through using the social sustainability indicators identified in the literature. The purpose of this investigation is to gain knowledge about the complexity of the system involved. A case study is conducted on one of the largest retailers in Egypt. Data were collected through semi-structured interviews with managers and employees to determine the level of application and identify the major obstacles affecting the social sustainability in the retailing context. The work developed gives insights about the details and complexities of the application of social sustainability in developing countries, from the retailing perspective. The outcomes of this study will help managers to understand the enablers of social sustainability and will direct them to methods of sound implementation. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=developing%20countries" title="developing countries">developing countries</a>, <a href="https://publications.waset.org/abstracts/search?q=Egyptian%20retailing%20sector" title=" Egyptian retailing sector"> Egyptian retailing sector</a>, <a href="https://publications.waset.org/abstracts/search?q=sustainability" title=" sustainability"> sustainability</a>, <a href="https://publications.waset.org/abstracts/search?q=social%20sustainability" title=" social sustainability"> social sustainability</a> </p> <a href="https://publications.waset.org/abstracts/122328/investigating-the-application-of-social-sustainability-a-case-study-in-the-egyptian-retailing-sector" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/122328.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">140</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">160</span> Critical Path Segments Method for Scheduling Technique</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sherif%20M.%20Hafez">Sherif M.

CPM was useful for scheduling construction projects, but researchers had highlighted a number of serious drawbacks that limit its use as a decision support tool and lacks the ability to clearly record and represent detailed information. This paper discusses the drawbacks of CPM as a scheduling technique and presents a modified critical path method (CPM) model which is called critical path segments (CPS). The CPS scheduling mechanism addresses the problems of CPM in three ways: decomposing the activity duration of separated but connected time segments; all relationships among activities are converted into finish–to–start relationship; and analysis and calculations are made with forward path. Sample cases are included to illustrate the shortages in CPM, CPS full analysis and calculations are explained in details, and how schedules can be handled better with the CPS technique. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=construction%20management" title="construction management">construction management</a>, <a href="https://publications.waset.org/abstracts/search?q=scheduling" title=" scheduling"> scheduling</a>, <a href="https://publications.waset.org/abstracts/search?q=critical%20path%20method" title=" critical path method"> critical path method</a>, <a href="https://publications.waset.org/abstracts/search?q=critical%20path%20segments" title=" critical path segments"> critical path segments</a>, <a href="https://publications.waset.org/abstracts/search?q=forward%20pass" title=" forward pass"> forward pass</a>, <a href="https://publications.waset.org/abstracts/search?q=float" title=" float"> float</a>, <a href="https://publications.waset.org/abstracts/search?q=project%20control" title=" project control"> project control</a> </p> <a href="https://publications.waset.org/abstracts/17760/critical-path-segments-method-for-scheduling-technique" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/17760.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">352</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">159</span> Obstacle Detection and Path Tracking Application for Disables</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Aliya%20Ashraf">Aliya Ashraf</a>, <a href="https://publications.waset.org/abstracts/search?q=Mehreen%20Sirshar"> Mehreen Sirshar</a>, <a href="https://publications.waset.org/abstracts/search?q=Fatima%20Akhtar"> Fatima Akhtar</a>, <a href="https://publications.waset.org/abstracts/search?q=Farwa%20Kazmi"> Farwa Kazmi</a>, <a href="https://publications.waset.org/abstracts/search?q=Jawaria%20Wazir"> Jawaria Wazir</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Vision, the basis for performing navigational tasks, is absent or greatly reduced in visually impaired people due to which they face many hurdles.

This element can be used for the analysis of thin shell structures, no matter how the geometrical shape might be. Tests on standard problems have been examined. The convergence of the new formulated element is also compared to other types of quadrilateral shell elements. The presented shell element ‘ACM_RSBEC’ has been demonstrated to be effective and useful in analysing thin shell structures. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=finite%20element" title="finite element">finite element</a>, <a href="https://publications.waset.org/abstracts/search?q=flat%20shell%20element" title=" flat shell element"> flat shell element</a>, <a href="https://publications.waset.org/abstracts/search?q=strain%20based%20approach" title=" strain based approach"> strain based approach</a>, <a href="https://publications.waset.org/abstracts/search?q=static%20condensation" title=" static condensation"> static condensation</a> </p> <a href="https://publications.waset.org/abstracts/3307/modeling-thin-shell-structures-by-a-new-flat-shell-finite-element" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/3307.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">430</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">157</span> Exponential Spline Solution for Singularly Perturbed Boundary Value Problems with an Uncertain-But-Bounded Parameter </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Waheed%20Zahra">Waheed Zahra</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohamed%20El-Beltagy"> Mohamed El-Beltagy</a>, <a href="https://publications.waset.org/abstracts/search?q=Ashraf%20El%20Mhlawy"> Ashraf El Mhlawy</a>, <a href="https://publications.waset.org/abstracts/search?q=Reda%20Elkhadrawy"> Reda Elkhadrawy</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this paper, we consider singular perturbation reaction-diffusion boundary value problems, which contain a small uncertain perturbation parameter.

These instruments include targeted funding schemes and economy-wide instruments embedded in the tax code. The resulting complexity of incentives raises important questions around the coherence and effectiveness of these instruments for RE generation. This complexity is exacerbated by UK RE policy being nested within EU policy in a multi-level governance (MLG) setting. To gain analytical traction on such complexity, this study will analyse policies promoting the on-farm generation of energy for heat and power, from farm and food waste, via anaerobic digestion. Utilising both primary and secondary data, it seeks to address a particular lacuna in the academic literature. Via a localised, in-depth investigation into the complexity of policy instruments promoting RE, this study will help our theoretical understanding of the challenges that MLG and path dependency pressures present to policymakers of multi-dimensional policies. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=anaerobic%20digestion" title="anaerobic digestion">anaerobic digestion</a>, <a href="https://publications.waset.org/abstracts/search?q=energy" title=" energy"> energy</a>, <a href="https://publications.waset.org/abstracts/search?q=green" title=" green"> green</a>, <a href="https://publications.waset.org/abstracts/search?q=policy" title=" policy"> policy</a>, <a href="https://publications.waset.org/abstracts/search?q=renewable" title=" renewable"> renewable</a>, <a href="https://publications.waset.org/abstracts/search?q=tax" title=" tax"> tax</a>, <a href="https://publications.waset.org/abstracts/search?q=UK" title=" UK"> UK</a> </p> <a href="https://publications.waset.org/abstracts/37433/green-energy-fiscal-incentives-and-conflicting-signals-analysing-the-challenges-faced-in-promoting-on-farm-waste-to-energy-projects" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/37433.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">370</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">155</span> A Discourse Study of Multimodal Intertextuality in Egyptian Social Media Memes</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ola%20Hafez">Ola Hafez</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This study examines the way selected Egyptian digitally mediated memes utilize intertextuality as a means of expression. It is motivated by the emerging digital socio-political humorous practice using various forms of political commentary in Egyptian social media. One of these forms involves the use of memes incorporating (often doctored) video frames taken from Egyptian plays, films and songs, and relocated in a different socio-political context, often with a caption that re-appropriates the frame for the purpose of critical commentary, thus juxtaposing the socio-political phenomena being addressed and the Egyptian artistic and cultural heritage. The paper presents a discourse study of a convenience sample of a recent social media campaign and carries out two levels of analysis. At the micro level, the study pinpoints the various modes of intertextuality employed, including verbal as well as visual intertextuality in the light of the work of social semiotics by Kress and van Leeuwen. At the macro level, the paper sheds light on the socio-political implications of such practice in the light of Political Discourse Analysis. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=digitally%20mediated%20discourse" title="digitally mediated discourse">digitally mediated discourse</a>, <a href="https://publications.waset.org/abstracts/search?q=discourse%20analysis" title=" discourse analysis"> discourse analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=Egyptian%20Arabic" title=" Egyptian Arabic"> Egyptian Arabic</a>, <a href="https://publications.waset.org/abstracts/search?q=intertextuality" title=" intertextuality"> intertextuality</a>, <a href="https://publications.waset.org/abstracts/search?q=memes" title=" memes"> memes</a>, <a href="https://publications.waset.org/abstracts/search?q=multimodality" title=" multimodality"> multimodality</a>, <a href="https://publications.waset.org/abstracts/search?q=political%20discourse%20analysis" title=" political discourse analysis"> political discourse analysis</a> </p> <a href="https://publications.waset.org/abstracts/101735/a-discourse-study-of-multimodal-intertextuality-in-egyptian-social-media-memes" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/101735.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">154</span> Vertical Distribution of Heavy Metals and Enrichment in Core Marine Sediments of East Malaysia by INAA and ICP-MS </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ahmadreza%20Ashraf">Ahmadreza Ashraf</a>, <a href="https://publications.waset.org/abstracts/search?q=Elias%20Saion"> Elias Saion</a>, <a href="https://publications.waset.org/abstracts/search?q=Elham%20Gharib%20Shahi"> Elham Gharib Shahi</a>, <a href="https://publications.waset.org/abstracts/search?q=Chee%20Kong%20Yap"> Chee Kong Yap</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohd%20Suhaimi%20Hamzah"> Mohd Suhaimi Hamzah</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Fifty-five core marine sediments from three locations at South China Sea and one location each at Sulu Sea and Sulawesi Sea of coastal East Malaysia was analyzed for heavy metals using Instrumental Neutron Activation Analysis and Inductively Coupled Plasma Mass Spectroscopy.

Blockchain technology is a vital proliferation technique that recuperates the food supply chain traceability process. While tracing is the core of the food supply chain; still, a complex system mitigates the exceptional risk of food contamination, foodborne, food waste, and food fraud. In addition, the upsurge of food supply chain data variance and variety in the traceability system requires complete transparency, a secure, steadfast, sustainable, and efficient approach to face the food supply chain challenges. On the other hand, blockchain technical aspects merged with a detailed implementation plan, the advantages and challenges in food traceability have not been much elucidated for small and medium enterprises (SMEs.) This paper demonstrated the advantages and challenges of applying blockchain in SMEs combined with the success stories of firms implementing blockchain to cover the gap. Moreover, blockchain architecture in SMEs and how technology, organization, and environment frameworks can guarantee the success of blockchain implementation have been revealed. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=blockchain%20technology" title="blockchain technology">blockchain technology</a>, <a href="https://publications.waset.org/abstracts/search?q=small%20and%20medium%20enterprises" title=" small and medium enterprises"> small and medium enterprises</a>, <a href="https://publications.waset.org/abstracts/search?q=food%20traceability" title=" food traceability"> food traceability</a>, <a href="https://publications.waset.org/abstracts/search?q=blockchain%20architecture" title=" blockchain architecture"> blockchain architecture</a> </p> <a href="https://publications.waset.org/abstracts/155034/food-traceability-for-small-and-medium-enterprises-using-blockchain-technology" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/155034.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">190</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">151</span> Urban Land Cover from GF-2 Satellite Images Using Object Based and Neural Network Classifications</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Lamyaa%20Gamal%20El-Deen%20Taha">Lamyaa Gamal El-Deen Taha</a>, <a href="https://publications.waset.org/abstracts/search?q=Ashraf%20Sharawi"> Ashraf Sharawi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> China launched satellite GF-2 in 2014.

For this purpose, the aging times adjusted 48, 56, 64, and 72 min. The obtained particles were characterized by x-ray diffraction spectroscopy (XRD), scanning electron microscopy (SEM), transmitted electron microscopy (TEM), and Brunauer–Emmett–Teller (BET). As a result, XRD patterns confirmed the formation of CeO2 nanoparticles. SEM and TEM images illustrated the nano-particles with cluster shape, spherical and a nano-size range which was in agreement with XRD results. The finest particles (7.3 nm) was obtained at the optimum condition which was aging time of 48 min, calcination temperature at 400 ⁰C, and cerium concentration of 0.004 mol.

Comparisons were undertaken between the different formulas supported by the results of in-situ Cone Penetration Tests (CPT). Based on this study, a guide for engineers for using the proper formula can be adopted with consideration of soil type and characteristics. The Egyptian Code which relies on the results of some formulas is involved in the study as a guiding aspect in the pile design. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=pile%20load%20formula" title="pile load formula">pile load formula</a>, <a href="https://publications.waset.org/abstracts/search?q=load%20test%20of%20piles" title=" load test of piles"> load test of piles</a>, <a href="https://publications.waset.org/abstracts/search?q=CPT" title=" CPT"> CPT</a>, <a href="https://publications.waset.org/abstracts/search?q=Egyptian%20code" title=" Egyptian code"> Egyptian code</a> </p> <a href="https://publications.waset.org/abstracts/108649/assessment-of-adequacy-of-pile-load-determination-formulas" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/108649.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">152</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">148</span> Dependency Theory on Examining the Relationship between the United States and the Middle East: In the Case of Iran, Saudi Arabia, and Turkey</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Abdelhafez%20Abdel%20Hafez">Abdelhafez Abdel Hafez</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Dependency theory was developed since 1950s, with economic concerns. It divided the world into two parts, the states of the peripheral (third world countries) and the states of the core (the developed capitalist countries). Another perspective developed to the theory with the implementation of the idea of semi-peripheral states in the new world order. With these divisions (core, peripheral, semi-peripheral) this study aims to develop a concept from the perspective of dependency theory, to understand the nature of the relationship of the U.S. with the Middle East Regions through its relation with Iran, Saudi Arabia, and Turkey. The tested countries (Saudi Arabia, Iran and Turkey) are seeking a foothold and influential role in the region. The paper argued that the U.S. directs its policies toward the region, in the way to guarantee no country of the region will be in semi-peripheral level (that could create competitions or danger on the U.S. interest). Therefore, U.S. policies in the region have varied from declaring war to diplomatic channels and sometimes ignoring. The paper is based on the dependency theory, and other international relations theories used to study the Middle East in the international context. <p class="card-text"><strong>Keywords:</strong> <a
