By harnessing AI-driven tools, students and educators can collaboratively explore a spectrum of design possibilities, stimulate innovative ideation, and engage in multidimensional design processes. This paper investigates the ways in which AI contributes to architectural creativity by facilitating generative design, pattern recognition, virtual reality experiences, and sustainable design optimization. Furthermore, the study examines the balance between AI-enhanced creativity and the preservation of core principles of architectural design/education, ensuring that technology is harnessed to augment rather than replace foundational design skills. Through an exploration of Egypt's architectural heritage and contemporary challenges, this research underscores how AI can synergize with cultural context and historical insights to inspire cutting-edge architectural solutions. By analyzing AI's impact on nurturing creativity among Egyptian architecture students, this paper seeks to contribute to the ongoing discourse on the integration of technology within global architectural education paradigms. It is hoped that this research will guide the thoughtful incorporation of AI in fostering creativity while preserving the authenticity and richness of architectural design education in Egypt and beyond. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=architecture" title="architecture">architecture</a>, <a href="https://publications.waset.org/abstracts/search?q=artificial%20intelligence" title=" artificial intelligence"> artificial intelligence</a>, <a href="https://publications.waset.org/abstracts/search?q=architecture%20education" title=" architecture education"> architecture education</a>, <a href="https://publications.waset.org/abstracts/search?q=Egypt" title=" Egypt"> Egypt</a> </p> <a href="https://publications.waset.org/abstracts/171800/investigating-the-role-of-artificial-intelligence-in-developing-creativity-in-architecture-education-in-egypt-a-case-study-of-design-studios" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/171800.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">1605</span> Numerical Simulation of the Flow around Wing-In-Ground Effect (WIG) Craft</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=A.%20Elbatran">A.

The simulated results have done using two EM software and show good agreement with the measured results for the fabricated antenna. Then a designing of two elements patch antenna array for UWB in the frequency band of 3.1-10 GHz is presented in this paper. The array is constructed by means of feeding two omni-directional modified circular patch elements with a modified power divider. Experimental results show that the array has a stable radiation pattern and low return loss over a broad bandwidth of 64% (3.1–10 GHz). Due to its planar profile, physically compact size, wide impedance bandwidth, directive performance over a wide bandwidth proposed antenna is a good candidate for portable UWB applications and other UWB integrated circuits. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=ultra%20wide%20band" title="ultra wide band">ultra wide band</a>, <a href="https://publications.waset.org/abstracts/search?q=radiation%20performance" title=" radiation performance"> radiation performance</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=size%20miniaturized%20antenna" title=" size miniaturized antenna"> size miniaturized antenna</a> </p> <a href="https://publications.waset.org/abstracts/52829/modified-step-size-patch-array-antenna-for-uwb-wireless-applications" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/52829.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">258</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">1603</span> Leadership Styles in the Hotel Sector and Its Effect on Employees’ Creativity and Organizational Commitment</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Hatem%20Radwan%20Ibrahim%20Radwan">Hatem Radwan Ibrahim Radwan</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Leadership is crucial for hotel survival and success. It enables hotels to develop and compete effectively. This research intends to explore the implementation of six leadership styles by frontline hotel managers in four star hotels in Cairo and assess its impact on employees’ creativity and organizational commitment. The leadership patterns considered in this study includes: democratic, autocratic, laissez-faire, transformational, transactional, and ethical leaderships. Questionnaire was used as a research method to gather data. A structured survey was established and distributed on employees in Cairo’s four star hotels. A total of 284 questionnaire forms were returned and usable for statistical analysis. The results of this study identified that transactional and autocratic leadership were the prevalent styles used in four star hotels in Cairo. Two leadership styles proved to have significant high correlation and impact on employees’ creativity and organizational commitment including: transformational and democratic leadership. Besides, laissez-faire leadership was found had a smaller effect on employees’ creativity and ethical leadership had a lesser influence on employees’ commitment. The autocratic leadership had strong negative correlation and significant impact on both dependent variables. This research concludes that frontline hotel managers should adopt transformational and/or democratic leadership style in managing their subordinates. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=creativity" title="creativity">creativity</a>, <a href="https://publications.waset.org/abstracts/search?q=hotels" title=" hotels"> hotels</a>, <a href="https://publications.waset.org/abstracts/search?q=leadership%20styles" title=" leadership styles"> leadership styles</a>, <a href="https://publications.waset.org/abstracts/search?q=organizational%20commitment" title=" organizational commitment"> organizational commitment</a> </p> <a href="https://publications.waset.org/abstracts/124236/leadership-styles-in-the-hotel-sector-and-its-effect-on-employees-creativity-and-organizational-commitment" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/124236.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">145</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">1602</span> Rainfall-Runoff Forecasting Utilizing Genetic Programming Technique</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ahmed%20Najah%20Ahmed%20Al-Mahfoodh">Ahmed Najah Ahmed Al-Mahfoodh</a>, <a href="https://publications.waset.org/abstracts/search?q=Ali%20Najah%20Ahmed%20%20Al-Mahfoodh"> Ali Najah Ahmed Al-Mahfoodh</a>, <a href="https://publications.waset.org/abstracts/search?q=Ahmed%20Al-Shafie"> Ahmed Al-Shafie</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this study, genetic programming (GP) technique has been investigated in prediction of set of rainfall-runoff data.

During the past few years, the importance of using these platforms in the fields of media and government communication has increased, as well as at the level of individual use. In 2016, the National Media Council Law was issued to regulate traditional and new media field, and gave the council the power to oversee and undertake the media affairs in the state. NMC is mandated to: Develop the UAE’s media policy, Draft media legislation and ensure its execution and Prohibited media content ,Co-ordinate the media policy between the emirates in line with the UAE’s domestic and foreign policy, Ensure support for the federation and project national unity. All media organizations in the UAE must comply with the regulations and rules issued by council. Social media influencers have to be licensed by NMC if they accept paid ads to be published on their accounts. The study explores other laws concerning of new media and social media regulations and ethics including Combatting Cybercrimes law, Combating Discrimination and Hatred law, The Government Guidelines for social media users in the UAE, The Guidelines for the practices of electronic participation and social networking, Copyright Law, and Child Rights Law.

Numerical simulations are performed for two simplified vehicles: A slanted-back Ahmed body at Re=30 000 and a square back Ahmed body at Re=300 000. A comparison of the resolved and modeled physical flow scales is made with corresponding LES and experimental data for a better understanding of the performance of the PANS model. The PANS model is compared for coarse and fine grid resolutions and it is indicated that even a coarse-grid PANS simulation is able to produce fairly close flow predictions to those from a well-resolved LES simulation. The results indicate the possibility of improvement of the predictions by employing a finer grid resolution. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=partially-averaged%20Navier-Stokes" title="partially-averaged Navier-Stokes">partially-averaged Navier-Stokes</a>, <a href="https://publications.waset.org/abstracts/search?q=large%20eddy%20simulation" title=" large eddy simulation"> large eddy simulation</a>, <a href="https://publications.waset.org/abstracts/search?q=PANS" title=" PANS"> PANS</a>, <a href="https://publications.waset.org/abstracts/search?q=LES" title=" LES"> LES</a>, <a href="https://publications.waset.org/abstracts/search?q=Ahmed%20body" title=" Ahmed body"> Ahmed body</a> </p> <a href="https://publications.waset.org/abstracts/17810/partially-averaged-navier-stokes-for-computations-of-flow-around-three-dimensional-ahmed-bodies" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/17810.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">600</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">1598</span> Optimization of Scheduling through Altering Layout Using Pro-Model </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Zouhair%20Issa%20Ahmed">Zouhair Issa Ahmed</a>, <a href="https://publications.waset.org/abstracts/search?q=Ahmed%20Abdulrasool%20Ahmed"> Ahmed Abdulrasool Ahmed</a>, <a href="https://publications.waset.org/abstracts/search?q=Falah%20Hassan%20Abdulsada"> Falah Hassan Abdulsada</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper presents a layout of a factory using Pro-Model simulation by choosing the best layout that gives the highest productivity and least work in process.

In order to deliver water from resources to the users, many procedures should be taken by the water engineers. One of the main procedures to deliver water to the community is by designing pressurizer pipe networks for water. The main aim of this work is to calculate the water demand of a small town and then design a simple water network to distribute water resources among the town with the smallest losses. Literature has been mentioned to cover the main point related to water distribution. Moreover, the methodology has introduced two approaches to solve the research problem, one by the iterative method of Hardy-cross and the other by water software Pipe Flow. The results have introduced two main designs to satisfy the same research requirements. Finally, the researchers have concluded that the use of water software provides more abilities and options for water engineers. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=looping%20pipe%20networks" title="looping pipe networks">looping pipe networks</a>, <a href="https://publications.waset.org/abstracts/search?q=hardy%20cross%20networks%20accuracy" title=" hardy cross networks accuracy"> hardy cross networks accuracy</a>, <a href="https://publications.waset.org/abstracts/search?q=relative%20error%20of%20hardy%20cross%20method" title=" relative error of hardy cross method"> relative error of hardy cross method</a> </p> <a href="https://publications.waset.org/abstracts/156922/comparison-between-hardy-cross-method-and-water-software-to-solve-a-pipe-networking-design-problem-for-a-small-town" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/156922.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">165</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">1596</span> Mechanical Properties of a Soil Stabilized With a Portland Cement</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ahmed%20Emad%20Ahmed">Ahmed Emad Ahmed</a>, <a href="https://publications.waset.org/abstracts/search?q=Mostafa%20El%20Abd"> Mostafa El Abd</a>, <a href="https://publications.waset.org/abstracts/search?q=Ahmed%20Wakeb"> Ahmed Wakeb</a>, <a href="https://publications.waset.org/abstracts/search?q=Moahmmed%20Eissa"> Moahmmed Eissa</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Soil modification and reinforcing aims to increase soil shear strength and stiffness.

Materials and Methods: Ahmed Glaucoma Valve (AGV®; New World Medical, Rancho Cucamonga, CA, USA) is a flow restrictive, non-obstructive self-regulating valve system. Preoperative ocular evaluation included direct ophthalmoscopy and measurement of the intraocular pressure (IOP). The implant was examined and primed prior to implantation. The selected site of the valve implantation was the superior quadrant between the superior and lateral rectus muscles. A fornix-based incision was made through the conjunectiva and Tenon’s capsule. A pocket is formed by blunt dissection of Tenon’s capsule from the episclera. The body of the implant was inserted into the pocket with the leading edge of the device around 8-10 mm from the limbus. Results: No post operative complications were detected in the operated eyes except a persistent corneal edema occupied the upper half of the cornea in one case. Hyphaema was very mild and seen only in two cases which resolved quickly two days after surgery. Endoscopical evaluation for the operated eyes revealed a normal ocular fundus with clearly visible optic papilla, tapetum and retinal blood vessels. No evidence of hemorrhage, infection, adhesions or retinal abnormalities was detected. Conclusion: Ahmed glaucoma valve is safe and effective implant for treatment of uveitic glaucoma in dogs. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ahmed%20valve" title="Ahmed valve">Ahmed valve</a>, <a href="https://publications.waset.org/abstracts/search?q=endoscopy" title=" endoscopy"> endoscopy</a>, <a href="https://publications.waset.org/abstracts/search?q=glaucoma" title=" glaucoma"> glaucoma</a>, <a href="https://publications.waset.org/abstracts/search?q=ocular%20fundus" title=" ocular fundus"> ocular fundus</a> </p> <a href="https://publications.waset.org/abstracts/37794/the-clinical-use-of-ahmed-valve-implant-as-an-aqueous-shunt-for-control-of-uveitic-glaucoma-in-dogs" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/37794.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">587</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">1594</span> In Search of CO₂: Gravity and Magnetic Data for Eor Prospect Generation in Central Libya</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ahmed%20Saheel">Ahmed Saheel</a>, <a href="https://publications.waset.org/abstracts/search?q=Milad%20Ahmed%20Elmaradi"> Milad Ahmed Elmaradi</a>, <a href="https://publications.waset.org/abstracts/search?q=Tim%20Archer"> Tim Archer</a>, <a href="https://publications.waset.org/abstracts/search?q=Muammer%20Ahmed%20Aboaesha"> Muammer Ahmed Aboaesha</a>, <a href="https://publications.waset.org/abstracts/search?q=Abdulkhaliq%20Abdulmajid%20Altoubashi"> Abdulkhaliq Abdulmajid Altoubashi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Enhanced oil recovery using carbon dioxide (CO₂-EOR) is a method that can increase oil production beyond what is typically achievable using conventional recovery methods by injecting and hence storing, carbon dioxide (CO₂) in the oil reservoir. In Libya, plans are underway to source a proportion of this CO₂ from subsurface geology that is known from previous drilling to contain high volumes of CO₂. But first, these subsurface volumes need to be more clearly defined and understood. Focusing on the Al-Harouj region of central Libya, ground gravity and airborne magnetic data from the LPI database and the African Magnetic Mapping Project respectively have been prepared and processed by Libyan Petroleum Institute (LPI) and Reid Geophysics Limited (RGL) to produce a range of grids and related products suitable for interpreting geological structure and to make recommendations for subsequent work that will assist CO₂ exploration for purposes of enhanced oil recovery (EOR). <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=gravity%20anomaly" title="gravity anomaly">gravity anomaly</a>, <a href="https://publications.waset.org/abstracts/search?q=magnetic%20anomaly" title=" magnetic anomaly"> magnetic anomaly</a>, <a href="https://publications.waset.org/abstracts/search?q=DEDUCED%20lineaments" title=" DEDUCED lineaments"> DEDUCED lineaments</a>, <a href="https://publications.waset.org/abstracts/search?q=Total%20horizontal%20derivative" title=" Total horizontal derivative"> Total horizontal derivative</a>, <a href="https://publications.waset.org/abstracts/search?q=upward-continuation" title=" upward-continuation"> upward-continuation</a> </p> <a href="https://publications.waset.org/abstracts/165050/in-search-of-co2-gravity-and-magnetic-data-for-eor-prospect-generation-in-central-libya" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/165050.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">126</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">1593</span> Aerodynamic Investigation of Rear Vehicle by Geometry Variations on the Backlight Angle</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Saud%20Hassan">Saud Hassan</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper shows simulation for the prediction of the flow around the backlight angle of the passenger vehicle.

This paper described the airflow over the different car models with different backlight angles and also on the Ahmed model to determine the trailing vortices with the varying backlight angle of a passenger vehicle body. The CFD simulation is carried out with the Ahmed body which has simplified car model mainly used in automotive industry to investigate the flow over the car body surface. The main goal of the simulation is to study the behavior of trailing vortices of these models. In this paper the air flow over the slant angle of 0,5o, 12.5o, 20o, 30o, 40o are considered. As investigating on the rear backlight angle two dimensional flows occurred at the rear slant, on the other hand when the slant angle is 30o the flow become three dimensional.

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">1591</span> An Analysis of Methodological Approaches of Ahmed Cevdet and Fatma Aliye towards the Ottoman Historiography in a Comparative Context</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Aysen%20Muderrisoglu%20Esiner">Aysen Muderrisoglu Esiner</a> </p> <p class="card-text"><strong>Abstract:</strong></p> As an intellectual, scholar, bureaucrat, and statesman, Ahmed Cevdet Pasha (1822-1895) was the prominent figure of “Tanzimat” (reorganization) reforms of the Ottoman State while his daughter Fatma Aliye (1862-1936) was a novelist, columnist, essayist, and women’s rights activist. His father had numerous books on law, grammar, linguistics, logic, and astronomy, moreover, Aliye accepted as the first female novelist in the Turkish literature and the Islamic world. Even if she was better known as a novelist, she also published some works on philosophy, Islam, poetry. In addition, Aliye who was one of the pioneers of the Ottoman women’s movement, also wrote historical works. Her historical works which titled as Tarih-i Osmaninin Bir Devre-i Mühimmesi Kosova Zaferi-Ankara Hezimeti (An Important Era of the Ottoman History: Kosova Victory-Ankara Defeat), and Ahmed Cevdet Paşa ve Zamanı (Ahmed Cevdet Pasha and His Time) have been generally ignored in the literature. However, Aliye’s works in history field are worth being studied in terms of her methodological approach to the Ottoman historiography. On the other hand, written by Ahmed Cevdet Pasha, such as Tarih-i Cevdet (History of Cevdet), Tezâkir (Memoir), Mâruzat (Reports, the events that took place between 1839-1876, 1890), Kısas-ı Enbiya ve Tevârîh-i Hulefa (Retaliation of the Prophets and the History of Calips), Kırım ve Kafkas Tarihçesi (Crimean and Caucasian History) are the most important works in terms of historiography in the 19th century. In contrast to the traditional methodology, Cevdet Pasha brought a new understanding to the Ottoman historiography by making a synthesis between the traditional and modern methods. In this research, the historical works of these two prominent figures of the Ottoman State will be analyzed in terms of their approaches to the Ottoman historiography while evaluating the following questions: to what extent that their use of local and foreign historical sources and their handling of the historical events differ, or if it is possible to talk about a methodological similarities in terms of historiography. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ahmed%20Cevdet%20Pasha" title="Ahmed Cevdet Pasha">Ahmed Cevdet Pasha</a>, <a href="https://publications.waset.org/abstracts/search?q=Fatma%20Aliye" title=" Fatma Aliye"> Fatma Aliye</a>, <a href="https://publications.waset.org/abstracts/search?q=historiography" title=" historiography"> historiography</a>, <a href="https://publications.waset.org/abstracts/search?q=methodology" title=" methodology"> methodology</a> </p> <a href="https://publications.waset.org/abstracts/129590/an-analysis-of-methodological-approaches-of-ahmed-cevdet-and-fatma-aliye-towards-the-ottoman-historiography-in-a-comparative-context" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/129590.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">257</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">1590</span> Tax Avoidance and Leadership Replacement: Moderating Influence of Ownership and Political Connections</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Radwan%20Hussien%20Alkebsee">Radwan Hussien Alkebsee</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Under the argument that reputational costs deter firms from engaging in tax avoidance activities, this paper investigates the relationship between tax avoidance and forced CEO turnover. This study is based on a broad sample of Chinese listed companies spanning the period 2011 to 2018. The findings reveal that tax avoidance is positively associated with forced CEO turnover. This suggests that firms that engage in tax avoidance experience a high rate of leadership replacement. The findings also reveal that the positive association between tax avoidance and forced CEO turnover is pronounced for state-owned firms, firms with no political connections, and firms located in “more developed” regions with extensive tax enforcement action, while it is not for private firms, firms with political connections, and firms located in “less developed” regions with weak tax enforcement actions.

Mahmoud </a> </p> <p class="card-text"><strong>Abstract:</strong></p> Geodynamic investigations in the Aswan Lake region were started after the M=5.5 earthquake in 1981, triggered by the lake water fluctuations. Besides establishing the seismological networks, also the geodetic observations focused on the Kalabsha and Sayal fault zones were started. It was found that the Kalabsha fault is an active dextral strike-slip with normal component indicating uplift on its southern side. However, the annual velocity rates in both components do not exceed 2 mm/y, and do not therefore represent extremely active faulting. We also launched gravity monitoring in 1997, and performed another two campaigns in 2000 and 2002. The observed non- tidal temporal gravity changes indicate rather the flood water infiltration into the porous Nubian sandstone, than tectonic stress effect. The station nearest to the lake exhibited about 60 μGal positive gravity change within the 1997-2002 period. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=gravity%20monitoring" title="gravity monitoring">gravity monitoring</a>, <a href="https://publications.waset.org/abstracts/search?q=surface%20movements" title=" surface movements"> surface movements</a>, <a href="https://publications.waset.org/abstracts/search?q=Lake%20Aswan" title=" Lake Aswan"> Lake Aswan</a>, <a href="https://publications.waset.org/abstracts/search?q=groundwater%20change" title=" groundwater change"> groundwater change</a> </p> <a href="https://publications.waset.org/abstracts/36158/gravity-and-geodetic-control-of-geodynamic-activity-near-aswan-lake-egypt" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/36158.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">503</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">1588</span> Comparative Study for Power Systems Transient Stability Improvement Using SFCL ,SVC,TCBR </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sabir%20Messalti">Sabir Messalti</a>, <a href="https://publications.waset.org/abstracts/search?q=Ahmed%20Gherbi"> Ahmed Gherbi</a>, <a href="https://publications.waset.org/abstracts/search?q=Ahmed%20Bouchlaghem"> Ahmed Bouchlaghem </a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper presents comparative study for power systems transient stability improvement using three FACTS devices: the SVC(Static Var Compensator), the Thyristor Control Breaking Resistor (TCBR) and superconducting fault current limiter (SFCL)The transient stability is assessed by the criterion of relative rotor angles.

The bluff body considered for this work is Ahmed model with a rake angle of 25deg was and subjected to flow with a velocity of 40m/s having Reynolds number of 2.68million was analysed using a commercial Computational Fluid Dynamic (CFD) code Star CCM+. It was evident that pressure drag is the main source of drag on an Ahmed body from the initial study. Adding a roof fairing has delayed the flow separation and resulted in delaying wake formation, thus improving the pressure in near weak and reducing the wake region. Adding a roof fairing of height and length equal to 1/7H and 1/3L respectively has shown a drag reduction by 9%. However, an optimised fairing, which was obtained by changing height, length and width by 5% increase, recorded a drag reduction close 12%. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ahmed%20model" title="Ahmed model">Ahmed model</a>, <a href="https://publications.waset.org/abstracts/search?q=aerodynamic%20drag" title=" aerodynamic drag"> aerodynamic drag</a>, <a href="https://publications.waset.org/abstracts/search?q=passive%20flow%20control" title=" passive flow control"> passive flow control</a>, <a href="https://publications.waset.org/abstracts/search?q=roof%20fairing" title=" roof fairing"> roof fairing</a>, <a href="https://publications.waset.org/abstracts/search?q=wake%20formation" title=" wake formation"> wake formation</a> </p> <a href="https://publications.waset.org/abstracts/68872/investigating-the-influence-of-roof-fairing-on-aerodynamic-drag-of-a-bluff-body" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/68872.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">442</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">1586</span> The Impacts of Digital Marketing Activities on Customers' Purchase Intention via Brand Reputation and Awareness: Empirical Study</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Radwan%20Al%20Dwairi">Radwan Al Dwairi</a>, <a href="https://publications.waset.org/abstracts/search?q=Sara%20Melhem"> Sara Melhem</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Today’s billions of individuals are linked together in real-time using different types of social platforms.

Hence, it is one of the important topics to study in the engineering research. Ship and offshore structures are most exposed to corrosion due to the presence of corrosive medium of air and the seawater. Consequently, investigation of the corrosion behavior and properties over ship and offshore hulls is one of the important topics to study in the marine engineering research. Using sacrificial anode is the most popular solution for protecting marine structures from corrosion. Hence, this research investigates the extent of corrosion between the composite ship model and relative velocity of water, along with the sacrificial aluminum anode consumption and its degree of protection in seawater. In this study, the consumption rate of sacrificial aluminum anode with respect to relative velocity at different Reynold’s numbers was studied experimentally, and it was found that, the degree of cathodic protection represented by the cathode potential at a given distance from the aluminum anode was decreased slightly with increment of the relative velocity. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=corrosion" title="corrosion">corrosion</a>, <a href="https://publications.waset.org/abstracts/search?q=Reynold%27s%20numbers" title=" Reynold's numbers"> Reynold's numbers</a>, <a href="https://publications.waset.org/abstracts/search?q=sacrificial%20anode" title=" sacrificial anode"> sacrificial anode</a>, <a href="https://publications.waset.org/abstracts/search?q=velocity" title=" velocity"> velocity</a> </p> <a href="https://publications.waset.org/abstracts/62994/experimental-study-on-using-the-aluminum-sacrificial-anode-as-a-cathodic-protection-for-marine-structures" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/62994.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">556</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">1583</span> Vehicle to Vehicle Communication: Collision Avoidance Scenarios</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ahmed%20Emad">Ahmed Emad</a>, <a href="https://publications.waset.org/abstracts/search?q=Ahmed%20Salah"> Ahmed Salah</a>, <a href="https://publications.waset.org/abstracts/search?q=Abdelrahman%20Magdy"> Abdelrahman Magdy</a>, <a href="https://publications.waset.org/abstracts/search?q=Omar%20Rashid"> Omar Rashid</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohammed%20Adel"> Mohammed Adel</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This research paper discusses vehicle-to-vehicle technology as an important application of linear algebra.

The shortage in crash data collection in developing countries makes it difficult to fully understand and address road safety issues in these regions. In developing countries, crowd-sourced data can be a valuable tool for improving road safety, particularly in urban areas where the majority of road crashes occur. This study is -to our best knowledge- the first to develop safety performance functions using crowd-sourced data by adopting a negative binomial structure model and the Full Bayes model to investigate traffic safety for urban road networks and provide insights into the impact of roadway characteristics. Furthermore, as a part of the safety management process, network screening has been undergone through applying two different methods to rank the most hazardous road segments: PCR method (adopted in the Highway Capacity Manual HCM) as well as a graphical method using GIS tools to compare and validate. Lastly, recommendations were suggested for policymakers to ensure safer roads. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=crowdsourced%20data" title="crowdsourced data">crowdsourced data</a>, <a href="https://publications.waset.org/abstracts/search?q=road%20crashes" title=" road crashes"> road crashes</a>, <a href="https://publications.waset.org/abstracts/search?q=safety%20performance%20functions" title=" safety performance functions"> safety performance functions</a>, <a href="https://publications.waset.org/abstracts/search?q=Full%20Bayes%20models" title=" Full Bayes models"> Full Bayes models</a>, <a href="https://publications.waset.org/abstracts/search?q=network%20screening" title=" network screening"> network screening</a> </p> <a href="https://publications.waset.org/abstracts/187824/using-crowd-sourced-data-to-assess-safety-in-developing-countries-the-case-study-of-eastern-cairo-egypt" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/187824.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">52</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">1578</span> Interaction Effects of Vitamin D Supplementation and Aerobic Exercises on Balance and Physical Performance in Children with Down Syndrome</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mohamed%20A.%20Eid">Mohamed A.

They were divided randomly to two groups. The control group (n=19) received the CPTP, while the study group (n=19) received the CPTP, AE, and vitamin D in the form of an oral daily dose of vitamin D3 400 IU (Cholecalciferol). Evaluation of balance by using the Biodex Stability System and physical performance by using the six-minute walk test (6MWT)was performed before and after 12 weeks of the treatment program. Findings: All groups showed a significant improvement in balance and physical performance after treatment (p < 0.05). The study group showed a significant improvement in balance and physical performancecompared with that of the control group (p < 0.05). Conclusion: Vitamin D supplementation combined with AE and CPTP could improve balance and physical performance in children with DS. Therefore, vitamin D and AEshould be considered as adjunctive to the rehabilitation program of these children. <p class="card-text"><strong>Keywords:</strong> <a
