Nowadays, LWD devices (e.g., nuclear, sonic, resistivity) are mostly used commercially for geo-steering applications. Modern borehole resistivity tools are able to measure all components of the magnetic field by incorporating tilted coils. The depth of investigation of LWD tools is limited compared to the thickness of the geological layers. Thus, it is a common practice to approximate the Earth’s subsurface with a sequence of 1D models. For a 1D model, we can reduce the dimensionality of the problem using a Hankel transform. We can solve the resulting system of ordinary differential equations (ODEs) either (a) analytically, which results in a so-called semi-analytic method after performing a numerical inverse Hankel transform, or (b) numerically. Semi-analytic methods are used by the industry due to their high performance. However, they have major limitations, namely: -The analytical solution of the aforementioned system of ODEs exists only for piecewise constant resistivity distributions. For arbitrary resistivity distributions, the solution of the system of ODEs is unknown by today’s knowledge. -In geo-steering, we need to solve inverse problems with respect to the inversion variables (e.g., the constant resistivity value of each layer and bed boundary positions) using a gradient-based inversion method. Thus, we need to compute the corresponding derivatives. However, the analytical derivatives of cross-bedded formation and the analytical derivatives with respect to the bed boundary positions have not been published to the best of our knowledge. The main contribution of this work is to overcome the aforementioned limitations of semi-analytic methods by solving each 1D model (associated with each Hankel mode) using an efficient multi-scale finite element method. The main idea is to divide our computations into two parts: (a) offline computations, which are independent of the tool positions and we precompute only once and use them for all logging positions, and (b) online computations, which depend upon the logging position. With the above method, (a) we can consider arbitrary resistivity distributions along the 1D model, and (b) we can easily and rapidly compute the derivatives with respect to any inversion variable at a negligible additional cost by using an adjoint state formulation. Although the proposed method is slower than semi-analytic methods, its computational efficiency is still high. In the presentation, we shall derive the mathematical variational formulation, describe the proposed multi-scale finite element method, and verify the accuracy and efficiency of our method by performing a wide range of numerical experiments and comparing the numerical solutions to semi-analytic ones when the latest are available. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=logging-While-Drilling" title="logging-While-Drilling">logging-While-Drilling</a>, <a href="https://publications.waset.org/abstracts/search?q=resistivity%20measurements" title=" resistivity measurements"> resistivity measurements</a>, <a href="https://publications.waset.org/abstracts/search?q=multi-scale%20finite%20elements" title=" multi-scale finite elements"> multi-scale finite elements</a>, <a href="https://publications.waset.org/abstracts/search?q=Hankel%20transform" title=" Hankel transform"> Hankel transform</a> </p> <a href="https://publications.waset.org/abstracts/83953/a-fast-multi-scale-finite-element-method-for-geophysical-resistivity-measurements" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/83953.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">386</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">39</span> Evaluation of Traffic Noise Around Different Facilities Located in Silent Zones</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Khaled%20Shaaban">Khaled Shaaban</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Schools and hospitals are supposed to be located in silent zones. In these areas, it is expected to maintain low noise levels in order to promote a peaceful environment for studying or recovering. However, many of these facilities are located in urban areas and are subject to high levels of noise. In this study, an evaluation of traffic noise around schools and hospitals was conducted during different periods of the day. The results indicated that the noise is positively correlated with the traffic volume around these facilities. Locations with higher traffic volumes tend to have higher noise levels. The results also showed that the noise levels exceed the recommended values by the World Health Organization.

The accumulation of dust on the solar panels significantly degrades output from these panels. Hence, solar PV panels have to be cleaned manually or using costly automated cleaning methods. This paper focuses on initiating cleaning actions when required to reduce maintenance costs. The cleaning actions are triggered only when the dust level exceeds a threshold value. The amount of dust accumulated on the PV panels is estimated using an artificial neural network (ANN). Experiments are conducted to collect the required data, which are used in the training of the ANN model. Then, this ANN model will be fed by the output power from solar panels, ambient temperature, and solar irradiance, and thus, it will be able to estimate the amount of dust accumulated on solar panels at these conditions. The model was tested on different case studies to confirm the accuracy of the developed model. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=machine%20learning" title="machine learning">machine learning</a>, <a href="https://publications.waset.org/abstracts/search?q=dust" title=" dust"> dust</a>, <a href="https://publications.waset.org/abstracts/search?q=PV%20panels" title=" PV panels"> PV panels</a>, <a href="https://publications.waset.org/abstracts/search?q=renewable%20energy" title=" renewable energy"> renewable energy</a> </p> <a href="https://publications.waset.org/abstracts/131092/application-of-artificial-neural-network-in-initiating-cleaning-of-photovoltaic-solar-panels" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/131092.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">144</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">32</span> Unreliable Production Lines with Simultaneously Unbalanced Operation Time Means, Breakdown, and Repair Rates</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sabry%20Shaaban">Sabry Shaaban</a>, <a href="https://publications.waset.org/abstracts/search?q=Tom%20McNamara"> Tom McNamara</a>, <a href="https://publications.waset.org/abstracts/search?q=Sarah%20Hudson"> Sarah Hudson </a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper investigates the benefits of deliberately unbalancing both operation time means (MTs) and unreliability (failure and repair rates) for non-automated production lines.The lines were simulated with various line lengths, buffer capacities, degrees of imbalance and patterns of MT and unreliability imbalance.

It was found that the best configurations are a balanced line arrangement and a monotone decreasing MT order, coupled with either a decreasing or a bowl unreliability configuration, with the first generally resulting in a reduced TR and the second leading to a lower ABL than those of a balanced line. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=unreliable%20production%20lines" title="unreliable production lines">unreliable production lines</a>, <a href="https://publications.waset.org/abstracts/search?q=unequal%20mean%20operation%20times" title=" unequal mean operation times"> unequal mean operation times</a>, <a href="https://publications.waset.org/abstracts/search?q=unbalanced%20failure%20and%20repair%20rates" title=" unbalanced failure and repair rates"> unbalanced failure and repair rates</a>, <a href="https://publications.waset.org/abstracts/search?q=throughput" title=" throughput"> throughput</a>, <a href="https://publications.waset.org/abstracts/search?q=average%20buffer%20level" title=" average buffer level"> average buffer level</a> </p> <a href="https://publications.waset.org/abstracts/19452/unreliable-production-lines-with-simultaneously-unbalanced-operation-time-means-breakdown-and-repair-rates" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/19452.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">486</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">31</span> Exercise program’s Effectiveness on Hepatic Fat Mobilization among Nonalcoholic Fatty Liver Patients</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Taher%20Eid%20Shaaban%20Ahmed%20Mousa">Taher Eid Shaaban Ahmed Mousa</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Non-Alcoholic fatty liver disease (NAFLD) is a major cause of multiple liver disorders, which strongly linked to a poor lifestyle.

There are three main factors affecting the design of soil replacement to gain these advantages. These factors are the type of replaced soil, characteristics, and thickness. The first two factors can be easily determined by laboratory and field control. This paper emphasizes on how to determine the thickness accurately for footing under centric axial load by limit state design method. The advantages of the method are the way of determining the thickness (independent of experience) and it takes into account the replaced and original or underneath soil characteristics and reaches the goals of replaced soils economically. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=design%20of%20soil%20replacement" title="design of soil replacement">design of soil replacement</a>, <a href="https://publications.waset.org/abstracts/search?q=LSD%20method" title=" LSD method"> LSD method</a>, <a href="https://publications.waset.org/abstracts/search?q=soil%20replacement" title=" soil replacement"> soil replacement</a>, <a href="https://publications.waset.org/abstracts/search?q=soil%20improvement" title=" soil improvement"> soil improvement</a> </p> <a href="https://publications.waset.org/abstracts/37928/design-of-soil-replacement-under-axial-centric-load-isolated-footing-by-limit-state-method" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/37928.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">351</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">29</span> Eco-Infrastructures: A Multidimensional System Approach for Urban Ecology</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=T.%20A.%20Mona%20M.%20Salem">T.

This leads to a kaleidoscopic view of the city that recognizes the interrelationships of energy, water, transportation, and solid waste. These interrelationships apply across sectors and with respect to the built form of the city. The paper aims at a long-term climate resilience of cities and their critical infrastructures, and sets out an argument for including an eco-infrastructure-based approach in strategies to address climate change. As these ecosystems have a critical role to play in building resilience and reducing vulnerabilities in cities, communities and economies at risk, the enhanced protection and management of ecosystems, biological resources and habitats can mitigate impacts and contribute to solutions as nations and cities strive to adapt to climate change. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=ecology" title="ecology">ecology</a>, <a href="https://publications.waset.org/abstracts/search?q=ecosystem" title=" ecosystem"> ecosystem</a>, <a href="https://publications.waset.org/abstracts/search?q=infrastructure" title=" infrastructure"> infrastructure</a>, <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=urban" title=" urban"> urban</a> </p> <a href="https://publications.waset.org/abstracts/10768/eco-infrastructures-a-multidimensional-system-approach-for-urban-ecology" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/10768.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">308</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">28</span> The Impact of Basic TRIZ Training on Psychological Flexibility among University Students</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Bakr%20M.%20Saeid">Bakr M.

We use a firm level panel that spans the period 2008 to 2012 of all listed firms on Abu Dhabi Stock Exchange and Dubai Financial Market. After constructing an index of corporate governance strength, we find a negative effect of corporate governance on firm performance. We, however, discover that corporate governance strength indirectly improves the negative influence of leverage on firm performance in normal times. On the contrary, the results completely reversed when there is a black swan event. Corporate governance strength plays a significantly negative role in moderating the relationship between leverage and firm performance during the financial crisis. We also reveal that corporate governance strength increases firms’ risk and deteriorates performance during crisis. Results provide evidence that corporate governance indirectly plays a completely different role in different time periods. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=corporate%20governance" title="corporate governance">corporate governance</a>, <a href="https://publications.waset.org/abstracts/search?q=firm%20performance" title=" firm performance"> firm performance</a>, <a href="https://publications.waset.org/abstracts/search?q=risk" title=" risk"> risk</a>, <a href="https://publications.waset.org/abstracts/search?q=leverage" title=" leverage"> leverage</a>, <a href="https://publications.waset.org/abstracts/search?q=the%20UAE" title=" the UAE"> the UAE</a> </p> <a href="https://publications.waset.org/abstracts/24418/corporate-governance-and-firm-performance-in-the-uae" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/24418.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">550</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">26</span> Desalination via Electrodialysis: A Newly Designed Fixed Bed Reactor Powered by Renewable Energy Source </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Hend%20Mesbah">Hend Mesbah</a>, <a href="https://publications.waset.org/abstracts/search?q=Yehia%20Youssef"> Yehia Youssef</a>, <a href="https://publications.waset.org/abstracts/search?q=Ibrahim%20%20Hassan"> Ibrahim Hassan</a>, <a href="https://publications.waset.org/abstracts/search?q=Shaaban%20Nosier"> Shaaban Nosier</a>, <a href="https://publications.waset.org/abstracts/search?q=Ahmed%20El-Shazly"> Ahmed El-Shazly</a>, <a href="https://publications.waset.org/abstracts/search?q=Ahmed%20Helal"> Ahmed Helal</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The problem of drinking water shortage is becoming more crucial nowadays as a result of the increased demand due to the population growth and the rise in the standard living. In recent years, desalination using electrodialysis powered by solar energy (PV-ED) is being widely used to help provide treated water and reduce the scarcity in water supply. In the present study, a water desalination laboratory scale ED cell with a fixed bed circulation system was designed, developed, and tested. The effect of three parameters (namely, cell voltage , flowrate, and salt concentration) on the removal percentage of salt ions was studied. The cell voltage was adjusted at 3 , 4 and 6 V. A flow rate of 5, 10, and 20 ml/s and an initial salt concentration of 2000, 5000, and 7000 ppm were investigated. The maximum salt percentage removal obtained was 52.5% at the lowest initial concentration (2000 ppm) and at the highest cell voltage (6 V). There was no significant effect of the flow rate on the removal percentage. A model of PV module has also been developed to calculate the dimensions of a solar cell based on the amount of energy consumed and it was calculated from the Overall ED cell voltage. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=desalination" title="desalination">desalination</a>, <a href="https://publications.waset.org/abstracts/search?q=electrodialysis" title=" electrodialysis"> electrodialysis</a>, <a href="https://publications.waset.org/abstracts/search?q=solar%20desalination" title=" solar desalination"> solar desalination</a>, <a href="https://publications.waset.org/abstracts/search?q=photovoltaic%20electrodialysis" title=" photovoltaic electrodialysis"> photovoltaic electrodialysis</a> </p> <a href="https://publications.waset.org/abstracts/123726/desalination-via-electrodialysis-a-newly-designed-fixed-bed-reactor-powered-by-renewable-energy-source" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/123726.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">147</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">25</span> An Experimental Study of the Parameters Affecting the Compression Index of Clay Soil</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Rami%20Rami%20Mahmoud%20Bakr">Rami Rami Mahmoud Bakr</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The constant rate of strain (CRS) test is a rapid technique that effectively measures specific properties of cohesive soil, including the rate of consolidation, hydraulic conductivity, compressibility, and stress history.

However, its limitations include an inability to handle strain-rate-dependent soil behavior, initial transient conditions, and pore pressure evaluation errors. There are currently no effective techniques for interpreting CRS data. In this study, experiments were performed to evaluate the effects of different parameters on CRS results.

This is especially true in the breezy waterfront settings. However, due to a number of factors, cross ventilation in buildings is usually studied by using oversimplified scenarios. It is then reasonable to study the impact of complex set of factors on the accuracy of predicting air flow rate because of wind driven cross ventilation. The objective of this paper is to provide architects with the tools necessary to achieve natural ventilation for cooling purposes in a waterfront urban canyon context. Also, urban canyons have not received much attention in terms of their impact on cross ventilation, and while we know how the wind flows between buildings in different urban canyon settings, the effect of the parallel-to-the-wind urban canyon on cross ventilation in buildings remains unclear. For this, we use detailed weather data, boundary layer correction factor, and CFD simulations to study the pressure patterns that form on the canyons surfaces in the case study of Alexandria. We found that the simplified numerical methods of calculating the cross ventilation in buildings can lead to inaccurate design decisions. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=cross%20ventilation" title="cross ventilation">cross ventilation</a>, <a href="https://publications.waset.org/abstracts/search?q=Alexandria" title=" Alexandria"> Alexandria</a>, <a href="https://publications.waset.org/abstracts/search?q=CFD" title=" CFD"> CFD</a>, <a href="https://publications.waset.org/abstracts/search?q=urban%20canyon" title=" urban canyon"> urban canyon</a> </p> <a href="https://publications.waset.org/abstracts/54913/cross-ventilation-in-waterfront-urban-canyons-the-case-study-of-alexandria" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/54913.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">255</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">23</span> Impact of Hepatitis C Virus Chronic Infection on Quality of Life in Egypt</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ammal%20M.%20Metwally">Ammal M.

Health related QoL assessment questionnaire with the 36-item Short Form used for assessment of the enrolled patients. The study showed no significant difference between HCV patients in different governorates as regards total QoL. Females, illiterate patients and those had bilharziasis, diabetes mellitus, hypertension or were depressed had significantly the lowest QoL score. HCV patients who knew the danger of the disease had significant lower mean score of physical and mental health components. Optimal care of overall well-being of HCV patients requires adequate knowledge of their neurological and psychological status. It is important to know that any patient will need to take the time to know that his new physical limitations do not limit him as a person, as soul, no matter what other people are thinking as a positive hopeful attitude is essential for combating HCV. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=hepatitis%20C%20virus%20chronic%20infection%20-%20physical%20health%20component%20and%20mental%20health%20component%20of%20QoL%E2%80%93%20total%20quality%20of%20life" title="hepatitis C virus chronic infection - physical health component and mental health component of QoL– total quality of life">hepatitis C virus chronic infection - physical health component and mental health component of QoL– total quality of life</a> </p> <a href="https://publications.waset.org/abstracts/3583/impact-of-hepatitis-c-virus-chronic-infection-on-quality-of-life-in-egypt" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/3583.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">449</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">22</span> Iron Removal from Aqueous Solutions by Fabricated Calcite Ooids</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Al-Sayed%20A.%20Bakr">Al-Sayed A.

In each vessel, the maximum bed capacity, which required to be filled, was 13.2 l and the bed filled in the vessels of ooids and GAC were 8.6, and 6.6 l, respectively. The operating conditions applied to the semi-pilot filtration unit were constant pH (7.5), different temperatures (293, 303 and 313 k), different flow rates (20, 30, 40, 50 and 60 l/min), different initial Fe(II) concentrations (15–105 mg/ l) and the calculated adsorbent masses were 34.1 and 123 g/l for GAC and calcite ooids, respectively. At higher temperature (313 k) and higher flow rate (60 l/min), the maximum adsorption capacities for ferrous ions by GAC and calcite ooids filters were 3.87 and 1.29 mg/g and at lower flow rate (20 l/min), the maximum adsorption capacities were 2.21 and 3.95 mg/g, respectively. From the experimental data, Freundlich and Langmuir adsorption isotherms were used to verify the adsorption performance. Therefore, the calcite ooids could act as new highly effective materials in iron removal from aqueous solutions. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=water%20treatment" title="water treatment">water treatment</a>, <a href="https://publications.waset.org/abstracts/search?q=calcite%20ooids" title=" calcite ooids"> calcite ooids</a>, <a href="https://publications.waset.org/abstracts/search?q=activated%20carbon" title=" activated carbon"> activated carbon</a>, <a href="https://publications.waset.org/abstracts/search?q=Fe%28II%29%20removal" title=" Fe(II) removal"> Fe(II) removal</a>, <a href="https://publications.waset.org/abstracts/search?q=filtration" title=" filtration"> filtration</a> </p> <a href="https://publications.waset.org/abstracts/85594/iron-removal-from-aqueous-solutions-by-fabricated-calcite-ooids" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/85594.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">21</span> Vibrancy in The City: The Problem of Sidi-Gaber Station Zone in Alexandria, Egypt</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Gihan%20Mosaad">Gihan Mosaad</a>, <a href="https://publications.waset.org/abstracts/search?q=Bakr%20Gomaa"> Bakr Gomaa</a>, <a href="https://publications.waset.org/abstracts/search?q=Rana%20Elbadri"> Rana Elbadri</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Modern parts of Alexandria city lack in vibrancy, causing a number of problems such as urban areas with poor security measures as well as weak economic state. Vibrancy provides a livable, attractive and secure environments; it also boosts the city’s economy and social life. Vibrant city is a city full of energy and life. To achieve this, a number of resources are needed; namely specific urban density, the availability of alternative modes of transportation and finally diversity of land-uses. Literature review shows no comprehensive study that assesses vibrancy in the streets of modern Alexandria. This study aims to measure the vibrancy potential in Sidi-Gaber station area thought the assessment of existing resources performance. Methods include literature reviews, surveying of existing case, questionnaire as well as GIS techniques. Expected results include GIS maps defining the vibrancy potentials in land use, density and statistical study regarding public transportation use in the area. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Alexandria" title="Alexandria">Alexandria</a>, <a href="https://publications.waset.org/abstracts/search?q=density" title=" density"> density</a>, <a href="https://publications.waset.org/abstracts/search?q=mixed%20use" title=" mixed use"> mixed use</a>, <a href="https://publications.waset.org/abstracts/search?q=transportation" title=" transportation"> transportation</a>, <a href="https://publications.waset.org/abstracts/search?q=vibrancy" title=" vibrancy"> vibrancy</a> </p> <a href="https://publications.waset.org/abstracts/52822/vibrancy-in-the-city-the-problem-of-sidi-gaber-station-zone-in-alexandria-egypt" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/52822.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">293</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">20</span> Examining Audiology Students: Clinical Reasoning Skills When Using Virtual Audiology Cases Aided With no Collaboration, Live Collaboration, and Virtual Collaboration</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ramy%20Shaaban">Ramy Shaaban</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The purpose of this study was to examine the difference in clinical reasoning skills of students when using virtual audiology cases with and without collaborative assistance from major learning approaches important to clinical reasoning skills and computer-based learning models: Situated Learning Theory, Social Development Theory, Scaffolding, and Collaborative Learning. A quasi-experimental design was conducted at two United States universities to examine whether there is a significant difference in clinical reasoning skills between three treatment groups using IUP Audiosim software. Two computer-based audiology case simulations were developed, and participants were randomly placed into the three groups: no collaboration, virtual collaboration, and live collaboration. The clinical reasoning data were analyzed using One-Way ANOVA and Tukey posthoc analyses. The results show that there was a significant difference in clinical reasoning skills between the three treatment groups. The score obtained by the no collaboration group was significantly less than the scores obtained by the virtual and live collaboration groups. Collaboration, whether virtual or in person, has a positive effect on students’ clinical reasoning. These results with audiology students indicate that combining collaboration models with scaffolding and embedding situated learning and social development theories into the design of future virtual patients has the potential to improve students’ clinical reasoning skills. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=clinical%20reasoning" title="clinical reasoning">clinical reasoning</a>, <a href="https://publications.waset.org/abstracts/search?q=virtual%20patients" title=" virtual patients"> virtual patients</a>, <a href="https://publications.waset.org/abstracts/search?q=collaborative%20learning" title=" collaborative learning"> collaborative learning</a>, <a href="https://publications.waset.org/abstracts/search?q=scaffolding" title=" scaffolding"> scaffolding</a> </p> <a href="https://publications.waset.org/abstracts/140721/examining-audiology-students-clinical-reasoning-skills-when-using-virtual-audiology-cases-aided-with-no-collaboration-live-collaboration-and-virtual-collaboration" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/140721.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">214</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">19</span> Development of a Practical Screening Measure for the Prediction of Low Birth Weight and Neonatal Mortality in Upper Egypt</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Prof.%20Ammal%20Mokhtar%20Metwally">Prof. Ammal Mokhtar Metwally</a>, <a href="https://publications.waset.org/abstracts/search?q=Samia%20M.%20Sami"> Samia M.

The present study aimed to determine a simple, easy, reliable anthropometric measure(s) that can predict LBW) and neonatal mortality. Methods: A prospective cohort study of 570 babies born in districts of El Menia governorate, Egypt (where most deliveries occurred at home) was examined at birth. Newborn weight, length, head, chest, mid-arm, and thigh circumferences were measured. Follow up of the examined neonates took place during their first four weeks of life to report any mortalities. The most predictable anthropometric measures were determined using the statistical package of SPSS, and multiple Logistic regression analysis was performed.: Results: Head and chest circumferences with cut-off points < 33 cm and ≤ 31.5 cm, respectively, were the significant predictors for LBW. They carried the best combination of having the highest sensitivity (89.8 % & 86.4 %) and least false negative predictive value (1.4 % & 1.7 %). Chest circumference with a cut-off point ≤ 31.5 cm was the significant predictor for neonatal mortality with 83.3 % sensitivity and 0.43 % false negative predictive value. Conclusion: Using chest circumference with a cut-off point ≤ 31.5 cm is recommended as a single simple anthropometric measurement for the prediction of both LBW and neonatal mortality. The predicted measure could act as a substitute for weighting newborns in communities where scales to weigh them are not routinely available. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=low%20birth%20weight" title="low birth weight">low birth weight</a>, <a href="https://publications.waset.org/abstracts/search?q=neonatal%20mortality" title=" neonatal mortality"> neonatal mortality</a>, <a href="https://publications.waset.org/abstracts/search?q=anthropometric%20measures" title=" anthropometric measures"> anthropometric measures</a>, <a href="https://publications.waset.org/abstracts/search?q=practical%20screening" title=" practical screening"> practical screening</a> </p> <a href="https://publications.waset.org/abstracts/162775/development-of-a-practical-screening-measure-for-the-prediction-of-low-birth-weight-and-neonatal-mortality-in-upper-egypt" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/162775.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">99</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">18</span> Perception Towards Using E-learning with Stem Students Whose Programs Require Them to Attend Practical Sections in Laboratories during Covid-19</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Youssef%20A.%20Yakoub">Youssef A.

The educational institutions around the world have been fighting since Covid-19 hit the world last December to keep the educational process unchanged for all students. E-learning was a must for almost all US universities during the pandemic. It was specifically more challenging to use eLearning instead of regular classes among students who take practical education. The aim of this study is to examine the perception of STEM students towards using eLearning instead of traditional methods during their practical study. Focus groups of STEM students studying at a western Pennsylavian, mid-size university were interviewed. Semi-structured interviews were designed to get an insight on students’ perception towards the alternative educational methods they used in the past seven months. Using convenient sampling, four students were chosen from different STEM fields: science of physics, technology, electrical engineering, and mathematics. The interview was primarily about the extent to which these students were satisfied, and their educational needs were met through distance education during the pandemic. The interviewed students were generally able to do a satisfactory performance during their virtual classes, but they were not satisfied enough with the learning methods. The main challenges they faced included the inability to have real practical experience, insufficient materials posted by the faculty, and some technical problems associated with their study. However, they reported they were satisfied with the simulation programs they had. They reported these simulations provided them with a good alternative to their traditional practical education. In conclusion, this study highlighted the challenges students face during the pandemic. It also highlighted the various learning tools students see as good alternatives to their traditional education. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=eLearning" title="eLearning">eLearning</a>, <a href="https://publications.waset.org/abstracts/search?q=STEM%20education" title=" STEM education"> STEM education</a>, <a href="https://publications.waset.org/abstracts/search?q=COVID-19%20crisis" title=" COVID-19 crisis"> COVID-19 crisis</a>, <a href="https://publications.waset.org/abstracts/search?q=online%20practical%20training" title=" online practical training"> online practical training</a> </p> <a href="https://publications.waset.org/abstracts/131033/perception-towards-using-e-learning-with-stem-students-whose-programs-require-them-to-attend-practical-sections-in-laboratories-during-covid-19" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/131033.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">134</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">17</span> Types of Innovation Management Office and Their Roles and Responsibilities in Supporting the Innovation Management Process from Organisational Strategic Foresight to Managing Innovation Project Portfolios</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Bakr%20Zade">Bakr Zade</a>, <a href="https://publications.waset.org/abstracts/search?q=Paolo%20Cervera"> Paolo Cervera</a> </p> <p class="card-text"><strong>Abstract:</strong></p> With the aim of maximising return on innovation investments, organisations create central units to support successful implementation of innovation management initiatives. The support units–referred to in this research as innovation management offices (IMOs)–range from small teams of innovation management champions to fully resourced centres of excellence for innovation management. However, roles and responsibilities of IMOs vary in different organisations. This research investigates the different types of IMO in organisations, based on their different roles and responsibilities in supporting innovation management processes. The research uses grounded theory methodology to uncover an IMO taxonomy from emergent concepts during innovation management maturity assessment exercises in twelve organisations from the United Kingdom and the United Arab Emirates. The taxonomy distinguishes five types of IMO, based on their roles and responsibilities in supporting innovation management processes, from organisational strategic foresight to managing innovation management project portfolios. The IMO taxonomy addresses a gap in research into innovation management support in organisations and offers a practical framework that diverse organisations can appreciate and use in designing IMOs that are aligned with their innovation management visions and strategies. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=future%20foresight" title="future foresight">future foresight</a>, <a href="https://publications.waset.org/abstracts/search?q=future%20shaping" title=" future shaping"> future shaping</a>, <a href="https://publications.waset.org/abstracts/search?q=innovation%20management" title=" innovation management"> innovation management</a>, <a href="https://publications.waset.org/abstracts/search?q=innovation%20management%20office" title=" innovation management office"> innovation management office</a>, <a href="https://publications.waset.org/abstracts/search?q=portfolio%20management" title=" portfolio management"> portfolio management</a> </p> <a href="https://publications.waset.org/abstracts/80156/types-of-innovation-management-office-and-their-roles-and-responsibilities-in-supporting-the-innovation-management-process-from-organisational-strategic-foresight-to-managing-innovation-project-portfolios" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/80156.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">396</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">16</span> Assessment of Cytotoxic and Genotoxic Effect of Tartrazine in Both Male and Female Albino Rats</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Alaa%20F.%20A.%20Bakr">Alaa F.

Nano-Ceramic coatings are considered ideal coatings on materials that can significantly improve the surface properties, including anti-fouling, self-cleaning, corrosion resistance, wear resistance, anti-scratch, waterproof, anti-acid rain and anti-asphalt. Furthermore, various techniques have been utilized to fabricate a range of different ceramic coatings with more desirable properties on Nano-ceramics, which make the materials usually used in in-service environments and worth mentioning that the practical part of this study will be applied in one of the most important architectural applications due to the contamination-free conditions provided by it in the manufacturing industry. Without cleanrooms, products will become contaminated and either malfunction or infect people with bacteria. Cleanrooms are used for the manufacture of items used in computers, cars, airplanes, spacecraft, televisions, disc players and many other electronic and mechanical devices, as well as the manufacture of medicines, medical devices, and foods. The aim of this study will be to examine the Nano-ceramics on porcelain and glass panels. The investigation will be included fabrications, methods, surface properties and applications in clean rooms. The unfamiliarity in this study is using Nano-ceramics in clean rooms instead of using them on metallic materials. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=nano-ceramic%20coating" title="nano-ceramic coating">nano-ceramic coating</a>, <a href="https://publications.waset.org/abstracts/search?q=clean%20rooms" title=" clean rooms"> clean rooms</a>, <a href="https://publications.waset.org/abstracts/search?q=porcelain" title=" porcelain"> porcelain</a>, <a href="https://publications.waset.org/abstracts/search?q=surface%20properties" title=" surface properties"> surface properties</a> </p> <a href="https://publications.waset.org/abstracts/152096/nano-ceramics-materials-in-clean-rooms-properties-and-characterization" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/152096.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">109</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">14</span> Earthquake Relocations and Constraints on the Lateral Velocity Variations along the Gulf of Suez, Using the Modified Joint Hypocenter Method Determination</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Abu%20Bakr%20Ahmed%20Shater">Abu Bakr Ahmed Shater</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Hypocenters of 250 earthquakes recorded by more than 5 stations from the Egyptian seismic network around the Gulf of Suez were relocated and the seismic stations correction for the P-wave is estimated, using the modified joint hypocenter method determination. Five stations TR1, SHR, GRB, ZAF and ZET have minus signs in the station P-wave travel time corrections and their values are -0.235, -0.366, -0.288, -0.366 and -0.058, respectively. It is possible to assume that, the underground model in this area has a particular characteristic of high velocity structure in which the other stations TR2, RDS, SUZ, HRG and ZNM have positive signs and their values are 0.024, 0.187, 0.314, 0.645 and 0.145, respectively. It is possible to assume that, the underground model in this area has particular characteristic of low velocity structure. The hypocenteral location determined by the Modified joint hypocenter method is more precise than those determined by the other routine work program. This method simultaneously solves the earthquake locations and station corrections. The station corrections reflect, not only the different crustal conditions in the vicinity of the stations, but also the difference between the actual and modeled seismic velocities along each of the earthquake - station ray paths. The stations correction obtained is correlated with the major surface geological features in the study area. As a result of the relocation, the low velocity area appears in the northeastern and southwestern sides of the Gulf of Suez, while the southeastern and northwestern parts are of high velocity area. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=gulf%20of%20Suez" title="gulf of Suez">gulf of Suez</a>, <a href="https://publications.waset.org/abstracts/search?q=seismicity" title=" seismicity"> seismicity</a>, <a href="https://publications.waset.org/abstracts/search?q=relocation%20of%20hypocenter" title=" relocation of hypocenter"> relocation of hypocenter</a>, <a href="https://publications.waset.org/abstracts/search?q=joint%20hypocenter%20determination" title=" joint hypocenter determination"> joint hypocenter determination</a> </p> <a href="https://publications.waset.org/abstracts/36770/earthquake-relocations-and-constraints-on-the-lateral-velocity-variations-along-the-gulf-of-suez-using-the-modified-joint-hypocenter-method-determination" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/36770.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">358</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">13</span> Cross Ventilation Potential in an Array of Building Blocks: The Case Study of Alexandria</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Bakr%20Gomaa">Bakr Gomaa</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Wind driven Cross ventilation is achieved when air moves indoors due to the pressure difference on the building envelope. This is especially important in breezy moderate to humid settings in which fast air flow can promote thermal comfort. Studies have shown that the use of simple building forms or ignoring the urban context when studying natural ventilation can lead to inaccurate results. In this paper, the impact of the urban form of a regular array of buildings is investigated to define the impact of this urban setting on cross ventilation potential. The objective of this paper is to provide the necessary tools to achieve natural ventilation for cooling purposes in an array of building blocks context. The array urban form has been studied before for natural ventilation purposes yet to the best of our knowledge no study has considered the relationship between the urban form and the pressure patterns that develop on the buildings envelope for cross ventilation. For this we use detailed weather data for a case study city of Alexandria (Egypt), as well as a validated CFD simulations to investigate the cross ventilation potential in terms of pressure patterns in waterfront as well as in-city wind flows perpendicular to the buildings array. it was found that for both waterfront and in-city wind speeds the windows needed for cross ventilation in rear raws of the array are significantly larger than those needed for front raw. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Alexandria" title="Alexandria">Alexandria</a>, <a href="https://publications.waset.org/abstracts/search?q=CFD" title=" CFD"> CFD</a>, <a href="https://publications.waset.org/abstracts/search?q=cross%20ventilation" title=" cross ventilation"> cross ventilation</a>, <a href="https://publications.waset.org/abstracts/search?q=pressure%20coefficient" title=" pressure coefficient"> pressure coefficient</a> </p> <a href="https://publications.waset.org/abstracts/56728/cross-ventilation-potential-in-an-array-of-building-blocks-the-case-study-of-alexandria" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/56728.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">386</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">12</span> Screening Deformed Red Blood Cells Irradiated by Ionizing Radiations Using Windowed Fourier Transform</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Dahi%20Ghareab%20Abdelsalam%20Ibrahim">Dahi Ghareab Abdelsalam Ibrahim</a>, <a href="https://publications.waset.org/abstracts/search?q=R.%20H.%20Bakr"> R.

The real values of the complex image are used to extract the best fitting of the deformed cell boundary. Male albino rats are irradiated by γ-rays from ⁶⁰Co. The male albino rats are anesthetized with ether, and then blood samples are collected from the eye vein by heparinized capillary tubes for studying the radiation-damaging effect in-vivo by the proposed windowed Fourier transform. The peripheral blood films are prepared according to the Brown method. The peripheral blood film is photographed by using an Automatic Image Contour Analysis system (SAMICA) from ELBEK-Bildanalyse GmbH, Siegen, Germany. The SAMICA system is provided with an electronic camera connected to a computer through a built-in interface card, and the image can be magnified up to 1200 times and displayed by the computer. The images of the peripheral blood films are then analyzed by the windowed Fourier transform method to extract the precise deformation from the best fitting. Based on accurate deformation evaluation of the red blood cells, diseases can be diagnosed in their primary stages. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=windowed%20Fourier%20transform" title="windowed Fourier transform">windowed Fourier transform</a>, <a href="https://publications.waset.org/abstracts/search?q=red%20blood%20cells" title=" red blood cells"> red blood cells</a>, <a href="https://publications.waset.org/abstracts/search?q=phase%20wrapping" title=" phase wrapping"> phase wrapping</a>, <a href="https://publications.waset.org/abstracts/search?q=Image%20processing" title=" Image processing"> Image processing</a> </p> <a href="https://publications.waset.org/abstracts/161268/screening-deformed-red-blood-cells-irradiated-by-ionizing-radiations-using-windowed-fourier-transform" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/161268.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">85</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">11</span> Understanding the Caliphate and Jihad to Prevent Radicalization That Lead to Terrorism: The Role of Social Community in Southeast Asia</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Jordan%20Daud">Jordan Daud</a>, <a href="https://publications.waset.org/abstracts/search?q=Satriya%20Wibawa"> Satriya Wibawa</a>, <a href="https://publications.waset.org/abstracts/search?q=Wahyu%20Wardhana"> Wahyu Wardhana</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In the summer of 2014, the leaders of the Islamic State of Iraq and Syria proclaimed the founding of religious-political system known as the caliphate which titled Islamic State (IS). As Caliph, Abu Bakr Baghdadi advocated Jihad from the Ummah (the Muslim community) to defend the Islamic state from unbelievers. This call for Jihad by IS had encouraged some radical organization in Southeast Asia pledge allegiance to IS and established bases for IS operation in Southeast Asia. This development had increased security concern for possible terrorism action in Southeast Asia, which currently not very active due to counterterrorism efforts from ASEAN member states and its cooperation with the world. This paper firstly tries to draw understanding from Ulema (Muslim cleric) about the conception of caliphate and Jihad based on Quran and Hadith. Secondly, this paper will elaborate counterterrorism efforts from ASEAN countries to prevent radicalization and terrorism act in addressing the call for jihad to establish IS in Southeast Asia. The third, this paper will recommend the role of the social community, especially Ulema, in Southeast Asia to prevent the misunderstanding of Jihad which usually used by terrorist to justify their action. Hopefully, this social community role will decrease the radicalization of Muslim community in Southeast Asia alongside with the counterterrorism efforts to create secure and stable ASEAN community based on shared norm and values. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=caliphate" title="caliphate">caliphate</a>, <a
