The range of these effects regarding multiple kidney stone factors (size, presence of obstruction, and modality of treatment) in stone formers with and without diabetes has not been well explored in the literature to the best of the author's knowledge. Our goal is to investigate this unexplored correlation between diabetes and kidney stones by conducting a Cohort retrospective study to precisely evaluate the effects of this condition and the existence of complications in adult individuals with diabetes in Saudi Arabia in comparison to a non-diabetic control group. Methodology: This is a retrospective cohort study aiming to evaluate the range of effects of kidney stones in stone formers in a group of adults diagnosed with type 2 diabetes mellitus and adults without diabetes between 2017 and 2019 in Jeddah, Saudi Arabia. An IRB approval has been granted for this study. The data was analyzed using SPSS. The data was collected from the 1st of December 2022 until the 1st of March 2023. Results: A total of 254 individuals diagnosed with kidney stones were included, 127 of whom were adult individuals with type 2 diabetes, and 127 were non-diabetics. Our study shows that the individuals affected with diabetes were more likely to have larger kidney stones in comparison to individuals without diabetes (13.12 mm vs. 10.53 mm, p-value = 0.03). Moreover, individuals with hypertension and dyslipidemia also had significantly larger stones. On the other hand, no significant difference was found in the presence of obstruction and modality of treatment between the two groups. Conclusion: This study done in Saudi Arabia found that individuals with kidney stones who concurrently had diabetes formed larger kidney stones, and they were also found to have other comorbidities such as HTN, dyslipidemia, obesity, and renal disease. The significance of these findings could assist in the future of primary and secondary prevention of renal stones. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=kidney%20stone" title="kidney stone">kidney stone</a>, <a href="https://publications.waset.org/abstracts/search?q=type%202%20DM" title=" type 2 DM"> type 2 DM</a>, <a href="https://publications.waset.org/abstracts/search?q=metabolic%20syndrome" title=" metabolic syndrome"> metabolic syndrome</a>, <a href="https://publications.waset.org/abstracts/search?q=lithotripsy" title=" lithotripsy"> lithotripsy</a> </p> <a href="https://publications.waset.org/abstracts/172898/kidney-stones-in-individuals-living-with-diabetes-mellitus-at-king-abdul-aziz-medical-city-tertiary-care-center-jeddah-saudi-arabia-a-retrospective-cohort-study" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/172898.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">111</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">126</span> Risk Management in Islamic Banks: A Case Study of the Faisal Islamic Bank of Egypt</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mohamed%20Saad%20Ahmed%20Hussien">Mohamed Saad Ahmed Hussien</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper discusses the risk management in Islamic banks and aims to determine the difference in the practices and methods of risk management in those banks compared to the conventional banks, and to make a case study of the biggest Islamic bank in Egypt (Faisal Islamic Bank of Egypt) to identify the most important financial risks faced and how to manage those risks. It was found that Islamic banks face two types of risks. The first type is similar to the risks in conventional banks; the second type is the additional risks which facing the Islamic banks only as a result of some Islamic modes of financing. With regard to the risk management, Islamic banks such as conventional banks applied the regulatory rules issued by the Central Banks and the Basel Committee; Islamic banks also applied the instructions and procedures issued by the Islamic Financial Services Board (IFSB). Also, Islamic banks are similar to the conventional banks in the practices and methods which they use to manage the risks. And there are some factors that may affect the risk management in Islamic banks, such as the size of the bank and the efficiency of the administration and the staff of the bank. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=conventional%20banks" title="conventional banks">conventional banks</a>, <a href="https://publications.waset.org/abstracts/search?q=Faisal%20Islamic%20Bank%20of%20Egypt" title=" Faisal Islamic Bank of Egypt"> Faisal Islamic Bank of Egypt</a>, <a href="https://publications.waset.org/abstracts/search?q=Islamic%20banks" title=" Islamic banks"> Islamic banks</a>, <a href="https://publications.waset.org/abstracts/search?q=risk%20management" title=" risk management"> risk management</a> </p> <a href="https://publications.waset.org/abstracts/58497/risk-management-in-islamic-banks-a-case-study-of-the-faisal-islamic-bank-of-egypt" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/58497.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">459</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">125</span> Prevalence of Knee Pain and Risk Factors and Its Impact on Functional Impairment among Saudi Adolescents</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ali%20H.Alyami">Ali H.Alyami</a>, <a href="https://publications.waset.org/abstracts/search?q=Hussam%20Darraj"> Hussam Darraj</a>, <a href="https://publications.waset.org/abstracts/search?q=Faisal%20Hakami"> Faisal Hakami</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohammed%20Awaf"> Mohammed Awaf</a>, <a href="https://publications.waset.org/abstracts/search?q=Sulaiman%20Hamdi"> Sulaiman Hamdi</a>, <a href="https://publications.waset.org/abstracts/search?q=Nawaf%20Bakri"> Nawaf Bakri</a>, <a href="https://publications.waset.org/abstracts/search?q=Abdulaziz%20Saber"> Abdulaziz Saber</a>, <a href="https://publications.waset.org/abstracts/search?q=Khalid%20Hakami"> Khalid Hakami</a>, <a href="https://publications.waset.org/abstracts/search?q=Almuhanad%20Alyami"> Almuhanad Alyami</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohammed%20khashab"> Mohammed khashab</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Introduction: Adolescents frequently self-report pain, according to epidemiological research. The knee is one of the sites where the pain is most common. One of the main factors contributing to the number of years people spend disabled and having substantial personal, societal, and economic burdens globally are musculoskeletal disorders. Adolescents may have knee pain due to an abrupt, traumatic injury or an insidious, slowly building onset that neither the adolescent nor the parent is aware of. Objectives: The present study’s authors aimed to estimate the prevalence of knee pain in Saudi adolescents. Methods: This cross-sectional survey, carried out from June to November 2022, included 676 adolescents ages 10 to 18. Data are presented as frequencies and percentages for categorical variables. Analysis of variance (ANOVA) was used to compare means between groups, while the chi-square test was used for the comparison of categorical variables. Statistical significance was set at P< 0.05.Result: Adolescents were invited to take part in the study. 57.5% were girls, and 42.5% were males,68.8% were 676 aged between 15 and 18. The prevalence of knee pain was considerably high among females (26%), while it was 19.2% among males. Moreover, age was a significant predictor for knee pain; also BMI was significant for knee pain. Conclusion: Our study noted a high rate of knee pain among adolescents, so we need to raise awareness about risk factors. Adolescent knee pain can be prevented with conservative methods and some minor lifestyle/activity modifications. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=knee%20pain" title="knee pain">knee pain</a>, <a href="https://publications.waset.org/abstracts/search?q=prevalence%20of%20knee%20pain" title=" prevalence of knee pain"> prevalence of knee pain</a>, <a href="https://publications.waset.org/abstracts/search?q=exercise%20training" title=" exercise training"> exercise training</a>, <a href="https://publications.waset.org/abstracts/search?q=physical%20activity" title=" physical activity"> physical activity</a> </p> <a href="https://publications.waset.org/abstracts/161732/prevalence-of-knee-pain-and-risk-factors-and-its-impact-on-functional-impairment-among-saudi-adolescents" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/161732.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">111</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">124</span> The Secrecy Capacity of the Semi-Deterministic Wiretap Channel with Three State Information</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mustafa%20El-Halabi">Mustafa El-Halabi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> A general model of wiretap channel with states is considered, where the legitimate receiver and the wiretapper’s observations depend on three states S1, S2 and S3.

The aim of this paper is to explore public policy and morality principles that affect trademark registration and protection under Shari'a by using Kuwaiti law as a case study. The findings provide a better understanding of trademark recognition from the perspective of Shari'a and the requirements demanded by Islamic Shari'a, especially of those who deal with strict Shari'a jurisdiction countries. In addition, this understanding is required for corporations or legislators that wish to take into consideration Muslim consumers. The conclusion suggests that trademarks in Western and Islamic systems are controlled by a number of public policy and morality rules that have a direct effect on the registration and protection of trademarks. Regardless of the fact that there are many commonalities between the two systems, there are still fundamental differences. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=trademark" title="trademark">trademark</a>, <a href="https://publications.waset.org/abstracts/search?q=public%20policy%20and%20morality" title=" public policy and morality"> public policy and morality</a>, <a href="https://publications.waset.org/abstracts/search?q=Islamic%20sharia" title=" Islamic sharia"> Islamic sharia</a>, <a href="https://publications.waset.org/abstracts/search?q=western%20legal%20systems" title=" western legal systems"> western legal systems</a> </p> <a href="https://publications.waset.org/abstracts/170173/public-policy-and-morality-principles-as-grounds-for-refusal-of-trademarks-a-comparative-study-of-islamic-sharia-and-common-law" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/170173.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">76</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">120</span> Enhancing Learning Ability among Deaf Students by Using Photographic Images</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Aidah%20Alias">Aidah Alias</a>, <a href="https://publications.waset.org/abstracts/search?q=Mustaffa%20Halabi%20Azahari"> Mustaffa Halabi Azahari</a>, <a href="https://publications.waset.org/abstracts/search?q=Adzrool%20Idzwan%20Ismail"> Adzrool Idzwan Ismail</a>, <a href="https://publications.waset.org/abstracts/search?q=Salasiah%20Ahmad"> Salasiah Ahmad</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Education is one of the most important elements in a human life. Educations help us in learning and achieve new things in life. The ability of hearing gave us chances to hear voices and it is important in our communication. Hearing stories told by others; hearing news and music to create our creative and sense; seeing and hearing make us understand directly the message trying to deliver. But, what will happen if we are born deaf or having hearing loss while growing up? The objectives of this paper are to identify the current practice in teaching and learning among deaf students and to analyse an appropriate method in enhancing learning process among deaf students. A case study method was employed by using methods of observation and interview to selected deaf students and teachers. The findings indicated that the suitable method of teaching for deaf students is by using pictures and body movement. In other words, by combining these two medium of images and body movement, the best medium that the study suggested is by using video or motion pictures. The study concluded and recommended that video or motion pictures is recommended medium to be used in teaching and learning for deaf students. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=deaf" title="deaf">deaf</a>, <a href="https://publications.waset.org/abstracts/search?q=photographic%20images" title=" photographic images"> photographic images</a>, <a href="https://publications.waset.org/abstracts/search?q=visual%20communication" title=" visual communication"> visual communication</a>, <a href="https://publications.waset.org/abstracts/search?q=education" title=" education"> education</a>, <a href="https://publications.waset.org/abstracts/search?q=learning%20ability" title=" learning ability"> learning ability</a> </p> <a href="https://publications.waset.org/abstracts/3840/enhancing-learning-ability-among-deaf-students-by-using-photographic-images" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/3840.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">284</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">119</span> Nurse Schedule Problem in Mubarak Al Kabeer Hospital</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Khaled%20Al-Mansour">Khaled Al-Mansour</a>, <a href="https://publications.waset.org/abstracts/search?q=Nawaf%20Esmael"> Nawaf Esmael</a>, <a href="https://publications.waset.org/abstracts/search?q=Abdulaziz%20Al-Zaid"> Abdulaziz Al-Zaid</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohammed%20Al%20Ateeqi"> Mohammed Al Ateeqi</a>, <a href="https://publications.waset.org/abstracts/search?q=Ali%20Al-Yousfi"> Ali Al-Yousfi</a>, <a href="https://publications.waset.org/abstracts/search?q=Sayed%20Al-Zalzalah"> Sayed Al-Zalzalah</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this project we will create the new schedule of nurse according to the preference of them. We did our project in Mubarak Al Kabeer Hospital (in Kuwait). The project aims to optimize the schedule of nurses in Mubarak Al Kabeer Hospital. The schedule of the nurses was studied and understood well to do any modification for their schedule to make the nurses feel as much comfort as they are. First constraints were found to know what things we can change and what things we can’t, the hard constraints are the hospital and ministry policies where we can’t change anything about, and the soft constraints are things that make nurses more comfortable. Data were collected and nurses were interviewed to know what is more better for them. All these constraints and date have been formulated to mathematical equations. This report will first contain an introduction to the topic which includes details of the problem definition. It will also contain information regarding the optimization of a nurse schedule and its contents and importance; furthermore, the report will contain information about the data needed to solve the problem and how it was collected. The problem requires formulation and that is also to be shown. The methodology will be explained which will state what has already been done. We used the lingo software to find the best schedule for the nurse. The schedule has been made according to what the nurses prefer, and also took consideration of the hospital policy when we make the schedule. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=nurse%20schedule%20problem" title="nurse schedule problem">nurse schedule problem</a>, <a href="https://publications.waset.org/abstracts/search?q=Kuwait" title=" Kuwait"> Kuwait</a>, <a href="https://publications.waset.org/abstracts/search?q=hospital%20policy" title=" hospital policy"> hospital policy</a>, <a href="https://publications.waset.org/abstracts/search?q=optimization%20of%20schedules" title=" optimization of schedules"> optimization of schedules</a> </p> <a href="https://publications.waset.org/abstracts/9565/nurse-schedule-problem-in-mubarak-al-kabeer-hospital" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/9565.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">268</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">118</span> Economics of Oil and Its Stability in the Gulf Region </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Al%20Mutawa%20A.%20Amir">Al Mutawa A.

The random variations in the measured intensity of solar irradiance are due to clouds and, in the case of arid regions, dust storms which decrease the intensity of intensity of solar irradiance. Therefore, modeling PV power output using average, maximum, or minimum solar irradiance values is inefficient to predict power generation reliably. The overall objective of this paper is to predict the power output of PV modules using Monte Carlo approach based the weather and solar conditions measured in Kuwait. Given the 250 Wp PV module used in study, the average daily power output is 1021 Wh/day. The maximum power was generated in April and the minimum power was generated in January 1187 Wh/day and 823 Wh/day respectively. The certainty of the daily predictions varies seasonally and according to the weather conditions. The output predictions were far more certain in the summer months, for example, the 80% certainty range for August is 89 Wh/day, whereas the 80% certainty range for April is 250 Wh/day. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Monte%20Carlo" title="Monte Carlo">Monte Carlo</a>, <a href="https://publications.waset.org/abstracts/search?q=solar%20energy" title=" solar energy"> solar energy</a>, <a href="https://publications.waset.org/abstracts/search?q=variable%20renewable%20energy" title=" variable renewable energy"> variable renewable energy</a>, <a href="https://publications.waset.org/abstracts/search?q=Kuwait" title=" Kuwait"> Kuwait</a> </p> <a href="https://publications.waset.org/abstracts/99078/working-title-estimating-the-power-output-of-photovoltaics-in-kuwait-using-a-monte-carlo-approach" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/99078.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">131</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">116</span> Applications of Big Data in Education</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Faisal%20Kalota">Faisal Kalota</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Big Data and analytics have gained a huge momentum in recent years. Big Data feeds into the field of Learning Analytics (LA) that may allow academic institutions to better understand the learners’ needs and proactively address them. Hence, it is important to have an understanding of Big Data and its applications. The purpose of this descriptive paper is to provide an overview of Big Data, the technologies used in Big Data, and some of the applications of Big Data in education. Additionally, it discusses some of the concerns related to Big Data and current research trends. While Big Data can provide big benefits, it is important that institutions understand their own needs, infrastructure, resources, and limitation before jumping on the Big Data bandwagon. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=big%20data" title="big data">big data</a>, <a href="https://publications.waset.org/abstracts/search?q=learning%20analytics" title=" learning analytics"> learning analytics</a>, <a href="https://publications.waset.org/abstracts/search?q=analytics" title=" analytics"> analytics</a>, <a href="https://publications.waset.org/abstracts/search?q=big%20data%20in%20education" title=" big data in education"> big data in education</a>, <a href="https://publications.waset.org/abstracts/search?q=Hadoop" title=" Hadoop "> Hadoop </a> </p> <a href="https://publications.waset.org/abstracts/27525/applications-of-big-data-in-education" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/27525.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">426</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">115</span> The Applicability of Western Environmental Criminology Theories to the Arabic Context</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Nawaf%20Alotaibi">Nawaf Alotaibi</a>, <a href="https://publications.waset.org/abstracts/search?q=Andy%20Evans"> Andy Evans</a>, <a href="https://publications.waset.org/abstracts/search?q=Alison%20Heppenstall"> Alison Heppenstall</a>, <a href="https://publications.waset.org/abstracts/search?q=Nick%20Malleson"> Nick Malleson</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Throughout the last two decades, motor vehicle theft (MVT) has accounted for the largest proportion of property crime incidents in Saudi Arabia (SA). However, to date, few studies have investigated SA’s MVT problem. Those that have are primarily focused on the characteristics of car thieves, and most have overlooked any spatial-temporal distribution of MVT incidents and the characteristics of victims. This paper represents the first step in understanding this problem by reviewing the existing MVT studies contextualised within the theoretical frameworks developed in environmental criminology theories – originating in the West – and exploring to what extent they are relevant to the SA context. To achieve this, the paper has identified a range of key features in SA that are different from typical Western contexts, that could limit the appropriateness and capability of applying existing environmental criminology theories. Furthermore, despite these Western studies reviewed so far having introduced a number of explanatory variables for MVT rates, a range of significant elements are apparently absent in the current literature and this requires further analysis. For example, almost no attempts have been made to quantify the associations between the locations of vehicle theft, recovery of stolen vehicles, joyriding and traffic volume. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=environmental%20criminology%20theories" title="environmental criminology theories">environmental criminology theories</a>, <a href="https://publications.waset.org/abstracts/search?q=motor%20vehicle%20theft" title=" motor vehicle theft"> motor vehicle theft</a>, <a href="https://publications.waset.org/abstracts/search?q=Saudi%20Arabia" title=" Saudi Arabia"> Saudi Arabia</a>, <a href="https://publications.waset.org/abstracts/search?q=spatial%20analysis" title=" spatial analysis"> spatial analysis</a> </p> <a href="https://publications.waset.org/abstracts/44304/the-applicability-of-western-environmental-criminology-theories-to-the-arabic-context" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/44304.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">298</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">114</span> Osteochondroma of Clivus: An Unusual Cause of Headache</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Muhammad%20Faisal%20Khilji">Muhammad Faisal Khilji</a>, <a href="https://publications.waset.org/abstracts/search?q=Rana%20Shoaib%20Hamid"> Rana Shoaib Hamid</a>, <a href="https://publications.waset.org/abstracts/search?q=Asim%20Qureshi"> Asim Qureshi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> A fifty years old female presented in the emergency department of a tertiary care hospital with complaints of migraine type headache for the last few months.

It is due to abnormal vision development in childhood or infancy. Most importantly, vision loss is preventable or reversible with the right kind of intervention in most of the cases. Strabismus, sensory defects, and anisometropia are all well-known causes of amblyopia. However, ocular misalignment in Strabismus is considered the most common form of amblyopia worldwide. The risk of developing amblyopia increases in premature children, developmentally delayed or children who had brain lesions affecting the visual pathway. The prevalence of amblyopia varies between 2 to 5 % in the world according to the literature. Objective: To determine the different causes of Amblyopia in pediatric patients seen in ophthalmology clinic of a tertiary care center, i.e. King Faisal Specialist Hospital and Research Center (KFSH&RC). Methods: This is a hospital based, random retrospective, based on reviewing patient’s files in the Ophthalmology Department of KFSH&RC in Riyadh city, Kingdom of Saudi Arabia. Inclusion criteria: amblyopic pediatric patients who attended the clinic from 2015 to 2016, who are between 6 months and 18 years old. Exclusion Criteria: patients above 18 years of age and any patient who is uncooperative to obtain an accurate vision or a proper refraction. Detailed ocular and medical history are recorded. The examination protocol includes a full ocular exam, full cycloplegic refraction, visual acuity measurement, ocular motility and strabismus evaluation. All data were organized in tables and graphs and analyzed by statistician. Results: Our preliminary results will be discussed on spot by our corresponding author. Conclusions: We focused on this study on utilizing various examination techniques which enhanced our results and highlighted a distinguished correlation between amblyopia and its’ causes. This paper recommendation emphasizes on critical testing protocols to be followed among amblyopic patient, especially in tertiary care centers. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=amblyopia" title="amblyopia">amblyopia</a>, <a href="https://publications.waset.org/abstracts/search?q=amblyopia%20causes" title=" amblyopia causes"> amblyopia causes</a>, <a href="https://publications.waset.org/abstracts/search?q=amblyopia%20diagnostic%20criterion" title=" amblyopia diagnostic criterion"> amblyopia diagnostic criterion</a>, <a href="https://publications.waset.org/abstracts/search?q=amblyopia%20prevalence" title=" amblyopia prevalence"> amblyopia prevalence</a>, <a href="https://publications.waset.org/abstracts/search?q=Saudi%20Arabia" title=" Saudi Arabia"> Saudi Arabia</a> </p> <a href="https://publications.waset.org/abstracts/76933/analyzing-the-causes-of-amblyopia-among-patients-in-tertiary-care-center-retrospective-study-in-king-faisal-specialist-hospital-and-research-center" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/76933.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">159</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">111</span> Conversion in Islam: The Case of Iranian Converts to Christianity in Malaysia </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Gholamreza%20Nuei">Gholamreza Nuei</a>, <a href="https://publications.waset.org/abstracts/search?q=Faisal%20Ahmad%20Shah"> Faisal Ahmad Shah</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The way religion defines people’s identity is quite important in the majority of Muslim countries.

Acoustic emission (AE) and vibration analysis are some of the most accomplished techniques used for this purpose. Acoustic emission has the ability to detect the initial phase of component degradation. Moreover, it has been observed that the success of vibration analysis does not take place below 100 rpm rotational speed.

VLC systems are combined with orthogonal frequency division multiplexing (OFDM) to achieve high rate transmission and high spectral efficiency. In this paper, we investigate the Pilot-Assisted Channel Estimation for DC biased Optical OFDM (PACE-DCO-OFDM) systems to reduce the effects of the distortion on the transmitted signal. Least-square (LS) and linear minimum mean-squared error (LMMSE) estimators are implemented in MATLAB/Simulink to enhance the bit-error-rate (BER) of PACE-DCO-OFDM. Results show that DCO-OFDM system based on PACE scheme has achieved better BER performance compared to conventional system without pilot assisted channel estimation. Simulation results show that the proposed PACE-DCO-OFDM based on LMMSE algorithm can more accurately estimate the channel and achieves better BER performance when compared to the LS based PACE-DCO-OFDM and the traditional system without PACE. For the same signal to noise ratio (SNR) of 25 dB, the achieved BER is about 5×10<sup>-4</sup> for LMMSE-PACE and 4.2×10<sup>-3</sup> with LS-PACE while it is about 2×10<sup>-1</sup> for system without PACE scheme. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=channel%20estimation" title="channel estimation">channel estimation</a>, <a href="https://publications.waset.org/abstracts/search?q=OFDM" title=" OFDM"> OFDM</a>, <a href="https://publications.waset.org/abstracts/search?q=pilot-assist" title=" pilot-assist"> pilot-assist</a>, <a href="https://publications.waset.org/abstracts/search?q=VLC" title=" VLC"> VLC</a> </p> <a href="https://publications.waset.org/abstracts/108632/pilot-assisted-direct-current-biased-optical-orthogonal-frequency-division-multiplexing-visible-light-communication-system" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/108632.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">180</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">106</span> Anatomical Characteristics of Superior Gluteal Artery</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Nawaf%20Al-Kharashi">Nawaf Al-Kharashi</a>, <a href="https://publications.waset.org/abstracts/search?q=Waseem%20Al-Talalwah"> Waseem Al-Talalwah</a>, <a href="https://publications.waset.org/abstracts/search?q=Shorok%20Al%20Dorazi"> Shorok Al Dorazi</a>, <a href="https://publications.waset.org/abstracts/search?q=Roger%20Soames"> Roger Soames</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Superior gluteal artery is one of the largest branches of posterior division of the internal iliac artery. It passes between the lumbosacral and first sacral root to escape from the pelvic cavity through the grater sciatic foramen just above the piriformis. The current study includes 41 cadaver investigates the origin and branch of the superior gluteal artery and clarify the clinical significance. In present study, the superior gluteal artery arises from the posterior division of the internal iliac artery directly in 82.5% whereas it arises indirectly as from the sciatic artery in 15.9%. However, it is congenital absence in 1.6% which is compensated by sciatic artery. The sciatic nerve gains vascular supply from superior gluteal artery in two ways either during its course or giving lateral sacral artery in 27% and lumbar branches in 1.6%. It also supplies the adductors group and iliacus via giving obturator artery in 14.3% and in 1.6% respectively. The superior gluteal artery usually passes between lumbosacral trunk and first sacral root in 82.5% whereas it does not passes the sciatic roots as it arises behind them in 15.9%. With a variability of the superior gluteal artery origin, there is a variability of sciatic nerve roots supply. Further, the superior gluteal artery arising from sciatic artery behind the sciatic roots carries a high risk of intra-pelvic bleeding in case of posterior pelvic fracture. Prolonged ligation of the superior gluteal artery which gives lateral sacral artery may result in sciatic neuropathy. Therefore, surgeons have to be aware of the superior gluteal artery variation in origin, course and branches to reduce the iatrogenic faults. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=internal%20pudendal%20artery" title="internal pudendal artery">internal pudendal artery</a>, <a href="https://publications.waset.org/abstracts/search?q=inferior%20gluteal%20artery" title=" inferior gluteal artery"> inferior gluteal artery</a>, <a href="https://publications.waset.org/abstracts/search?q=superior%20gluteal%20artery" title=" superior gluteal artery"> superior gluteal artery</a>, <a href="https://publications.waset.org/abstracts/search?q=internal%20iliac%20artery.%20sciatic%20neuropathy" title=" internal iliac artery. sciatic neuropathy"> internal iliac artery. sciatic neuropathy</a>, <a href="https://publications.waset.org/abstracts/search?q=sciatic%20nerve" title=" sciatic nerve"> sciatic nerve</a> </p> <a href="https://publications.waset.org/abstracts/30966/anatomical-characteristics-of-superior-gluteal-artery" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/30966.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">350</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">105</span> Subdural Hematoma: A Rare Complication of ITP</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Muhammad%20Faisal%20Khilji">Muhammad Faisal Khilji</a>, <a href="https://publications.waset.org/abstracts/search?q=Rana%20Shoaib%20Hamid"> Rana Shoaib Hamid</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Subdural hematoma (SDH) is an extremely rare complication of immune thrombocytopenic purpura (ITP).

This is resulted in changing the behavior of the flood routing and consequently the flood hazard is tremendously increased in Kassala city. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=bed%20level" title="bed level">bed level</a>, <a href="https://publications.waset.org/abstracts/search?q=cross%20section" title=" cross section"> cross section</a>, <a href="https://publications.waset.org/abstracts/search?q=gash%20river" title=" gash river"> gash river</a>, <a href="https://publications.waset.org/abstracts/search?q=sedimentation" title=" sedimentation"> sedimentation</a> </p> <a href="https://publications.waset.org/abstracts/28631/rivers-bed-level-changing-pattern-due-to-sedimentation-case-study-gash-river-kassala-sudan" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/28631.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">541</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">99</span> Density-based Denoising of Point Cloud</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Faisal%20Zaman">Faisal Zaman</a>, <a href="https://publications.waset.org/abstracts/search?q=Ya%20Ping%20Wong"> Ya Ping Wong</a>, <a href="https://publications.waset.org/abstracts/search?q=Boon%20Yian%20Ng"> Boon Yian Ng</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Point cloud source data for surface reconstruction is usually contaminated with noise and outliers. To overcome this, we present a novel approach using modified kernel density estimation (KDE) technique with bilateral filtering to remove noisy points and outliers. First we present a method for estimating optimal bandwidth of multivariate KDE using particle swarm optimization technique which ensures the robust performance of density estimation. Then we use mean-shift algorithm to find the local maxima of the density estimation which gives the centroid of the clusters. Then we compute the distance of a certain point from the centroid. Points belong to outliers then removed by automatic thresholding scheme which yields an accurate and economical point surface. The experimental results show that our approach comparably robust and efficient. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=point%20preprocessing" title="point preprocessing">point preprocessing</a>, <a href="https://publications.waset.org/abstracts/search?q=outlier%20removal" title=" outlier removal"> outlier removal</a>, <a href="https://publications.waset.org/abstracts/search?q=surface%20reconstruction" title=" surface reconstruction"> surface reconstruction</a>, <a href="https://publications.waset.org/abstracts/search?q=kernel%20density%20estimation" title=" kernel density estimation "> kernel density estimation </a> </p> <a href="https://publications.waset.org/abstracts/37614/density-based-denoising-of-point-cloud" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/37614.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">344</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">98</span> Taxonomy of Threats and Vulnerabilities in Smart Grid Networks</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Faisal%20Al%20Yahmadi">Faisal Al Yahmadi</a>, <a href="https://publications.waset.org/abstracts/search?q=Muhammad%20R.%20Ahmed"> Muhammad R.

Consequently, any break in electric power is probably going to affect the general activity. To make the power supply smooth and efficient, a smart grid network is introduced which uses communication technology. In any communication network, security is essential. It has been observed from several recent incidents that adversary causes an interruption to the operation of networks. In order to resolve the issues, it is vital to understand the threats and vulnerabilities associated with the smart grid networks. In this paper, we have investigated the threats and vulnerabilities in Smart Grid Networks (SGN) and the few solutions in the literature. Proposed solutions showed developments in electricity theft countermeasures, Denial of services attacks (DoS) and malicious injection attacks detection model, as well as malicious nodes detection using watchdog like techniques and other solutions. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=smart%20grid%20network" title="smart grid
