Numerical simulations are performed for two simplified vehicles: A slanted-back Ahmed body at Re=30 000 and a square back Ahmed body at Re=300 000. A comparison of the resolved and modeled physical flow scales is made with corresponding LES and experimental data for a better understanding of the performance of the PANS model. The PANS model is compared for coarse and fine grid resolutions and it is indicated that even a coarse-grid PANS simulation is able to produce fairly close flow predictions to those from a well-resolved LES simulation. The results indicate the possibility of improvement of the predictions by employing a finer grid resolution. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=partially-averaged%20Navier-Stokes" title="partially-averaged Navier-Stokes">partially-averaged Navier-Stokes</a>, <a href="https://publications.waset.org/abstracts/search?q=large%20eddy%20simulation" title=" large eddy simulation"> large eddy simulation</a>, <a href="https://publications.waset.org/abstracts/search?q=PANS" title=" PANS"> PANS</a>, <a href="https://publications.waset.org/abstracts/search?q=LES" title=" LES"> LES</a>, <a href="https://publications.waset.org/abstracts/search?q=Ahmed%20body" title=" Ahmed body"> Ahmed body</a> </p> <a href="https://publications.waset.org/abstracts/17810/partially-averaged-navier-stokes-for-computations-of-flow-around-three-dimensional-ahmed-bodies" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/17810.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">600</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">1603</span> Effectiveness of Myofascial Release Technique in Treatment of Sacroiliac Joint Hypo-Mobility in Postnatal Women</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ahmed%20A.%20Abd%20El%20Rahim">Ahmed A.

Myofascial release technique (MFR) is an application of low-intensity, prolonged stretch to myofascial structures to improve function by increasing the sliding properties of restricted myofascial tissues. Purpose: This study was designed to investigate the effect of MFR on postnatal SIJ hypo-mobility. Materials and Methods: Fifty postnatal women complaining of SIJ hypo-mobility participated in this study. Their ages ranged from 26 to 35 yrs., and their body mass index (BMI) didn`t exceed 30 kg/m2. They were randomly assigned to two equal groups, group A (Gr. A) and group B (Gr. B). Both groups received three sessions per week for eight successive weeks. Gr. A received a traditional physical therapy program, while Gr. B received a traditional physical therapy program in addition to MFR. Doppler imaging of vibration was utilized to measure SIJ mobility pre- and post-intervention, and an electronic digital goniometer was used to measure back flexion and extension Range of motion. Results: Findings revealed a statistical improvement in post-intervention values of SIJ mobility in addition to trunk flexion and extension ROM in Gr. B compared to Gr. A (P<0.001). Conclusion: Adding MFR to traditional physical therapy programs is highly recommended in the treatment of SIJ hypo-mobility in postnatal women. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=sacroiliac%20hypo-mobility" title="sacroiliac hypo-mobility">sacroiliac hypo-mobility</a>, <a href="https://publications.waset.org/abstracts/search?q=sacroiliac%20dysfunction" title=" sacroiliac dysfunction"> sacroiliac dysfunction</a>, <a href="https://publications.waset.org/abstracts/search?q=myofascial%20release%20technique" title=" myofascial release technique"> myofascial release technique</a>, <a href="https://publications.waset.org/abstracts/search?q=traditional%20physical%20therapy" title=" traditional physical therapy"> traditional physical therapy</a>, <a href="https://publications.waset.org/abstracts/search?q=postnatal" title=" postnatal"> postnatal</a> </p> <a href="https://publications.waset.org/abstracts/157745/effectiveness-of-myofascial-release-technique-in-treatment-of-sacroiliac-joint-hypo-mobility-in-postnatal-women" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/157745.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">102</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">1602</span> Fractional Order Sallen-Key Filters</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ahmed%20Soltan">Ahmed Soltan</a>, <a href="https://publications.waset.org/abstracts/search?q=Ahmed%20G.%20Radwan"> Ahmed G.

One of the most important data analysis process on the microarray data set is feature selection. This process finds the most important genes that affect certain disease.

In order to deliver water from resources to the users, many procedures should be taken by the water engineers. One of the main procedures to deliver water to the community is by designing pressurizer pipe networks for water. The main aim of this work is to calculate the water demand of a small town and then design a simple water network to distribute water resources among the town with the smallest losses. Literature has been mentioned to cover the main point related to water distribution. Moreover, the methodology has introduced two approaches to solve the research problem, one by the iterative method of Hardy-cross and the other by water software Pipe Flow. The results have introduced two main designs to satisfy the same research requirements. Finally, the researchers have concluded that the use of water software provides more abilities and options for water engineers. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=looping%20pipe%20networks" title="looping pipe networks">looping pipe networks</a>, <a href="https://publications.waset.org/abstracts/search?q=hardy%20cross%20networks%20accuracy" title=" hardy cross networks accuracy"> hardy cross networks accuracy</a>, <a href="https://publications.waset.org/abstracts/search?q=relative%20error%20of%20hardy%20cross%20method" title=" relative error of hardy cross method"> relative error of hardy cross method</a> </p> <a href="https://publications.waset.org/abstracts/156922/comparison-between-hardy-cross-method-and-water-software-to-solve-a-pipe-networking-design-problem-for-a-small-town" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/156922.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">165</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">1598</span> A Two Phase VNS Algorithm for the Combined Production Routing Problem</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Nejah%20Ben%20Mabrouk">Nejah Ben Mabrouk</a>, <a href="https://publications.waset.org/abstracts/search?q=Bassem%20Jarboui"> Bassem Jarboui</a>, <a href="https://publications.waset.org/abstracts/search?q=Habib%20Chabchoub"> Habib Chabchoub</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Production and distribution planning is the most important part in supply chain management. In this paper, a NP-hard production-distribution problem for one product over a multi-period horizon is investigated. The aim is to minimize the sum of costs of three items: production setups, inventories and distribution, while determining, for each period, the amount produced, the inventory levels and the delivery trips.

Increased related morbidity of diabetes, hypertension and fatty liver disease, and complicated cardiovascular disease are inevitable. Boswellia serrata gum (Bos) is a promising traditional medicinal plant; it has several pharmacological properties, including anti-inflammatory, antioxidant, and antilipase activities. Probiotics (Bac) supplements have good benefits on health and MeS, whether it is supplemented in combination with prebiotics or alone. Microencapsulation helps to mask unpalatable taste and odor and deliver active ingredients to targeted organs. Methodology MeS rat model was produced by feeding rats with a high fat, high CHO diet (HFD). Bos was extracted, and both Bos and the probiotic were microencapsulated with a spray drier. Female rats were divided into 5 groups (N8). HFD control, control normal receiving basic diet, HFD treated, from the start of the experiment, either with encapsulated Bos, Bac and Bos or Bac only, all treatments were received for eight weeks (after approval from NRC animal ethical committee). Serum was collected to analyze lipid profile, blood sugar, liver and kidney functions, antioxidants, leptin, and progesterone. Rat's organs and body fat were weighed and collected for histopathology. Statistical analysis was done by use of one way Anova test in the SPSS program. Results showed control of elevated body weight, lipid profile, and glucose levels as well as decrease of body fat index and improvement of histopathology of liver and heart, especially in combination. Conclusion: We concluded that both microencapsulated Bos and probiotics have a controlling effect on MeS parameters. <p class="card-text"><strong>Keywords:</strong> <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=Boswellia%20serata" title=" Boswellia serata"> Boswellia serata</a>, <a href="https://publications.waset.org/abstracts/search?q=probiotic" title=" probiotic"> probiotic</a>, <a href="https://publications.waset.org/abstracts/search?q=micro-encapsulation" title=" micro-encapsulation"> micro-encapsulation</a>, <a href="https://publications.waset.org/abstracts/search?q=histopathology" title=" histopathology"> histopathology</a>, <a href="https://publications.waset.org/abstracts/search?q=liver%20steatosis" title=" liver steatosis"> liver steatosis</a> </p> <a href="https://publications.waset.org/abstracts/161022/microencapsulated-boswellia-serrata-and-probiotic-bacteria-acted-as-symbiotic-in-metabolic-syndrome-rat-model" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/161022.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">102</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">1596</span> Mechanical Properties of a Soil Stabilized With a Portland Cement</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ahmed%20Emad%20Ahmed">Ahmed Emad Ahmed</a>, <a href="https://publications.waset.org/abstracts/search?q=Mostafa%20El%20Abd"> Mostafa El Abd</a>, <a href="https://publications.waset.org/abstracts/search?q=Ahmed%20Wakeb"> Ahmed Wakeb</a>, <a href="https://publications.waset.org/abstracts/search?q=Moahmmed%20Eissa"> Moahmmed Eissa</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Soil modification and reinforcing aims to increase soil shear strength and stiffness.

Materials and Methods: Ahmed Glaucoma Valve (AGV®; New World Medical, Rancho Cucamonga, CA, USA) is a flow restrictive, non-obstructive self-regulating valve system. Preoperative ocular evaluation included direct ophthalmoscopy and measurement of the intraocular pressure (IOP). The implant was examined and primed prior to implantation. The selected site of the valve implantation was the superior quadrant between the superior and lateral rectus muscles. A fornix-based incision was made through the conjunectiva and Tenon’s capsule. A pocket is formed by blunt dissection of Tenon’s capsule from the episclera. The body of the implant was inserted into the pocket with the leading edge of the device around 8-10 mm from the limbus. Results: No post operative complications were detected in the operated eyes except a persistent corneal edema occupied the upper half of the cornea in one case. Hyphaema was very mild and seen only in two cases which resolved quickly two days after surgery. Endoscopical evaluation for the operated eyes revealed a normal ocular fundus with clearly visible optic papilla, tapetum and retinal blood vessels. No evidence of hemorrhage, infection, adhesions or retinal abnormalities was detected. Conclusion: Ahmed glaucoma valve is safe and effective implant for treatment of uveitic glaucoma in dogs. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ahmed%20valve" title="Ahmed valve">Ahmed valve</a>, <a href="https://publications.waset.org/abstracts/search?q=endoscopy" title=" endoscopy"> endoscopy</a>, <a href="https://publications.waset.org/abstracts/search?q=glaucoma" title=" glaucoma"> glaucoma</a>, <a href="https://publications.waset.org/abstracts/search?q=ocular%20fundus" title=" ocular fundus"> ocular fundus</a> </p> <a href="https://publications.waset.org/abstracts/37794/the-clinical-use-of-ahmed-valve-implant-as-an-aqueous-shunt-for-control-of-uveitic-glaucoma-in-dogs" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/37794.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">587</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">1594</span> Supervised Learning for Cyber Threat Intelligence</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Jihen%20Bennaceur">Jihen Bennaceur</a>, <a href="https://publications.waset.org/abstracts/search?q=Wissem%20Zouaghi"> Wissem Zouaghi</a>, <a href="https://publications.waset.org/abstracts/search?q=Ali%20Mabrouk"> Ali Mabrouk</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The major aim of cyber threat intelligence (CTI) is to provide sophisticated knowledge about cybersecurity threats to ensure internal and external safeguards against modern cyberattacks. Inaccurate, incomplete, outdated, and invaluable threat intelligence is the main problem. Therefore, data analysis based on AI algorithms is one of the emergent solutions to overcome the threat of information-sharing issues. In this paper, we propose a supervised machine learning-based algorithm to improve threat information sharing by providing a sophisticated classification of cyber threats and data.

Subsequently, the inhibition effect of PBRA on the corrosion of carbon steel in 1 M HCl was studied using electrochemical measurements such as potentiodynamic polarization (PDP) and electrochemical impedance spectroscopy (EIS). The results showed that the inhibition efficiency increased with concentration, reaching 87% at 10-³M. Furthermore, PBRA remained effective at temperatures ranging from 298 to 328 K. The adsorption of the inhibitor onto carbon steel was well described by the Langmuir adsorption isotherm.

In Libya, plans are underway to source a proportion of this CO₂ from subsurface geology that is known from previous drilling to contain high volumes of CO₂. But first, these subsurface volumes need to be more clearly defined and understood. Focusing on the Al-Harouj region of central Libya, ground gravity and airborne magnetic data from the LPI database and the African Magnetic Mapping Project respectively have been prepared and processed by Libyan Petroleum Institute (LPI) and Reid Geophysics Limited (RGL) to produce a range of grids and related products suitable for interpreting geological structure and to make recommendations for subsequent work that will assist CO₂ exploration for purposes of enhanced oil recovery (EOR). <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=gravity%20anomaly" title="gravity anomaly">gravity anomaly</a>, <a href="https://publications.waset.org/abstracts/search?q=magnetic%20anomaly" title=" magnetic anomaly"> magnetic anomaly</a>, <a href="https://publications.waset.org/abstracts/search?q=DEDUCED%20lineaments" title=" DEDUCED lineaments"> DEDUCED lineaments</a>, <a href="https://publications.waset.org/abstracts/search?q=Total%20horizontal%20derivative" title=" Total horizontal derivative"> Total horizontal derivative</a>, <a href="https://publications.waset.org/abstracts/search?q=upward-continuation" title=" upward-continuation"> upward-continuation</a> </p> <a href="https://publications.waset.org/abstracts/165050/in-search-of-co2-gravity-and-magnetic-data-for-eor-prospect-generation-in-central-libya" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/165050.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">126</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">1591</span> Investigation on The Feasibility of a Solar Desiccant Cooling System in Libya</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=A.%20S.%20Zgalei">A.

Technology advancements have enabled the development of it to do many excellent jobs as reconnaissance, surveillance, battle fighters, and communications relays. Simulating a small unmanned aerial vehicle (SUAV) dynamics and analyzing its behavior at the preflight stage is too important and more efficient. The first step in the UAV design is the mathematical modeling of the nonlinear equations of motion. In this paper, a survey with a standard method to obtain the full non-linear equations of motion is utilized,and then the linearization of the equations according to a steady state flight condition (trimming) is derived. This modeling technique is applied to an Ultrastick-25e fixed wing UAV to obtain the valued linear longitudinal and lateral models. At the end, the model is checked by matching between the behavior of the states of the non-linear UAV and the resulted linear model with doublet at the control surfaces. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=UAV" title="UAV">UAV</a>, <a href="https://publications.waset.org/abstracts/search?q=equations%20of%20motion" title=" equations of motion"> equations of motion</a>, <a href="https://publications.waset.org/abstracts/search?q=modeling" title=" modeling"> modeling</a>, <a href="https://publications.waset.org/abstracts/search?q=linearization" title=" linearization"> linearization</a> </p> <a href="https://publications.waset.org/abstracts/23317/modeling-of-a-small-unmanned-aerial-vehicle" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/23317.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">743</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">1588</span> An Analysis of Methodological Approaches of Ahmed Cevdet and Fatma Aliye towards the Ottoman Historiography in a Comparative Context</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Aysen%20Muderrisoglu%20Esiner">Aysen Muderrisoglu Esiner</a> </p> <p class="card-text"><strong>Abstract:</strong></p> As an intellectual, scholar, bureaucrat, and statesman, Ahmed Cevdet Pasha (1822-1895) was the prominent figure of “Tanzimat” (reorganization) reforms of the Ottoman State while his daughter Fatma Aliye (1862-1936) was a novelist, columnist, essayist, and women’s rights activist.

Her historical works which titled as Tarih-i Osmaninin Bir Devre-i Mühimmesi Kosova Zaferi-Ankara Hezimeti (An Important Era of the Ottoman History: Kosova Victory-Ankara Defeat), and Ahmed Cevdet Paşa ve Zamanı (Ahmed Cevdet Pasha and His Time) have been generally ignored in the literature. However, Aliye’s works in history field are worth being studied in terms of her methodological approach to the Ottoman historiography. On the other hand, written by Ahmed Cevdet Pasha, such as Tarih-i Cevdet (History of Cevdet), Tezâkir (Memoir), Mâruzat (Reports, the events that took place between 1839-1876, 1890), Kısas-ı Enbiya ve Tevârîh-i Hulefa (Retaliation of the Prophets and the History of Calips), Kırım ve Kafkas Tarihçesi (Crimean and Caucasian History) are the most important works in terms of historiography in the 19th century. In contrast to the traditional methodology, Cevdet Pasha brought a new understanding to the Ottoman historiography by making a synthesis between the traditional and modern methods. In this research, the historical works of these two prominent figures of the Ottoman State will be analyzed in terms of their approaches to the Ottoman historiography while evaluating the following questions: to what extent that their use of local and foreign historical sources and their handling of the historical events differ, or if it is possible to talk about a methodological similarities in terms of historiography. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ahmed%20Cevdet%20Pasha" title="Ahmed Cevdet Pasha">Ahmed Cevdet Pasha</a>, <a href="https://publications.waset.org/abstracts/search?q=Fatma%20Aliye" title=" Fatma Aliye"> Fatma Aliye</a>, <a href="https://publications.waset.org/abstracts/search?q=historiography" title=" historiography"> historiography</a>, <a href="https://publications.waset.org/abstracts/search?q=methodology" title=" methodology"> methodology</a> </p> <a href="https://publications.waset.org/abstracts/129590/an-analysis-of-methodological-approaches-of-ahmed-cevdet-and-fatma-aliye-towards-the-ottoman-historiography-in-a-comparative-context" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/129590.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">257</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">1587</span> Dental Management Particularities of Werner Syndrome: A Report of Two Cases</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Emna%20Abid">Emna Abid</a>, <a href="https://publications.waset.org/abstracts/search?q=Linda%20Chebbi"> Linda Chebbi</a>, <a href="https://publications.waset.org/abstracts/search?q=Yosra%20Mabrouk"> Yosra Mabrouk</a>, <a href="https://publications.waset.org/abstracts/search?q=Amel%20Labidi"> Amel Labidi</a>, <a href="https://publications.waset.org/abstracts/search?q=Lamia%20Mansour"> Lamia Mansour</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Werner syndrome (WS) is a rare genetic disorder inherited in an autosomal recessive pattern characterized by accelerated aging. While extensive research has been conducted on its systemic manifestations, the specific dental implications of WS remain poorly understood. The medical history and the oral health status of two patients diagnosed with WS were detailed. Our findings revealed a high prevalence of dental problems in both patients, including periodontitis, xerostomia, and temporomandibular joint disorders. This article aims to investigate the dental challenges faced by individuals with WS as well as the prosthetic options envisaged through two clinical cases contributing to a deeper understanding of the dental implications of WS and to choose the appropriate prosthetic solution in this population. Future research should focus on larger scale studies and clinical trials to validate these proposed strategies. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=adult%20progeria" title="adult progeria">adult progeria</a>, <a href="https://publications.waset.org/abstracts/search?q=clinical%20symptoms" title=" clinical symptoms"> clinical symptoms</a>, <a href="https://publications.waset.org/abstracts/search?q=oral%20manifestations" title=" oral manifestations"> oral manifestations</a>, <a href="https://publications.waset.org/abstracts/search?q=dental%20care" title=" dental care"> dental care</a>, <a href="https://publications.waset.org/abstracts/search?q=prosthetic%20management" title=" prosthetic management"> prosthetic management</a> </p> <a href="https://publications.waset.org/abstracts/186691/dental-management-particularities-of-werner-syndrome-a-report-of-two-cases" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/186691.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">51</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">1586</span> Comparative Study for Power Systems Transient Stability Improvement Using SFCL ,SVC,TCBR </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sabir%20Messalti">Sabir Messalti</a>, <a href="https://publications.waset.org/abstracts/search?q=Ahmed%20Gherbi"> Ahmed Gherbi</a>, <a href="https://publications.waset.org/abstracts/search?q=Ahmed%20Bouchlaghem"> Ahmed Bouchlaghem </a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper presents comparative study for power systems transient stability improvement using three FACTS devices: the SVC(Static Var Compensator), the Thyristor Control Breaking Resistor (TCBR) and superconducting fault current limiter (SFCL)The transient stability is assessed by the criterion of relative rotor angles.

The bluff body considered for this work is Ahmed model with a rake angle of 25deg was and subjected to flow with a velocity of 40m/s having Reynolds number of 2.68million was analysed using a commercial Computational Fluid Dynamic (CFD) code Star CCM+. It was evident that pressure drag is the main source of drag on an Ahmed body from the initial study. Adding a roof fairing has delayed the flow separation and resulted in delaying wake formation, thus improving the pressure in near weak and reducing the wake region. Adding a roof fairing of height and length equal to 1/7H and 1/3L respectively has shown a drag reduction by 9%. However, an optimised fairing, which was obtained by changing height, length and width by 5% increase, recorded a drag reduction close 12%. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ahmed%20model" title="Ahmed model">Ahmed model</a>, <a href="https://publications.waset.org/abstracts/search?q=aerodynamic%20drag" title=" aerodynamic drag"> aerodynamic drag</a>, <a href="https://publications.waset.org/abstracts/search?q=passive%20flow%20control" title=" passive flow control"> passive flow control</a>, <a href="https://publications.waset.org/abstracts/search?q=roof%20fairing" title=" roof fairing"> roof fairing</a>, <a href="https://publications.waset.org/abstracts/search?q=wake%20formation" title=" wake formation"> wake formation</a> </p> <a href="https://publications.waset.org/abstracts/68872/investigating-the-influence-of-roof-fairing-on-aerodynamic-drag-of-a-bluff-body" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/68872.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">442</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">1584</span> Study of Hydraulic and Tectonic Fracturation within Zemlet El Beidha Area (North Chott Range)</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Nabil%20Abaab">Nabil Abaab</a>, <a href="https://publications.waset.org/abstracts/search?q=Dhaou%20Akrout"> Dhaou Akrout</a>, <a href="https://publications.waset.org/abstracts/search?q=Riadh%20Ahmadi"> Riadh Ahmadi</a>, <a href="https://publications.waset.org/abstracts/search?q=Mabrouk%20Montacer"> Mabrouk Montacer</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The study of fluid pressure and its evolution have a critical importance as they lead to understanding the tectonic history of the region. Therefore, the present work focuses on a microtectonic study of tectonic and hydraulic fracture at the anticline structure of Zemlet El Beidha (North Chott range). The study and the analysis of several stations of tectonic and hydraulic fracture allow revealing the witnesses of a paléosurpression in the deposits of Lower Cretaceous (Bouhedma Formation). In fact, we noticed that the overpressure is directly involved in the creation of various types of fractures as evidenced by the different measures and the stereographic projections. Thus, the orientations of fibers of mineralization that fills the Beefs type fracture have the same direction as the main constraint. Furthermore, we discussed the different overpressure build-up mechanisms. The results showed that tectonics is likely, responsible for this anomaly. This is confirmed by the description of the fibers and the projection of the different measurements of Beefs. The mineralization transformation from gypsum to anhydrite is heavily involved in this stress regime especially in the presence of all necessary conditions of dehydration of gypsum. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Zemlet%20El%20Beidha" title="Zemlet El Beidha">Zemlet El Beidha</a>, <a href="https://publications.waset.org/abstracts/search?q=overpressure" title=" overpressure"> overpressure</a>, <a href="https://publications.waset.org/abstracts/search?q=tectonic%20fracture" title=" tectonic fracture"> tectonic fracture</a>, <a href="https://publications.waset.org/abstracts/search?q=hydraulic%20fracture" title=" hydraulic fracture"> hydraulic fracture</a>, <a href="https://publications.waset.org/abstracts/search?q=gypsum%20beefs" title=" gypsum beefs"> gypsum beefs</a> </p> <a href="https://publications.waset.org/abstracts/46713/study-of-hydraulic-and-tectonic-fracturation-within-zemlet-el-beidha-area-north-chott-range" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/46713.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">286</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">1583</span> Effects of Asphalt Modification with Nanomaterials on Fresh and Stored Bitumen</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ahmed%20W.%20Oda">Ahmed W.

Carbonaceous sorbents derived from local luffa cylindrica, were prepared by chemical activation methods using ZnCl2 as activating reagents. Adsorption of Cu (II) from aqueous solutions was investigated. The effects of pH, initial adsorbent concentration, the effect of particle size, initial metal ion concentration and temperature were studied in batch experiments. The maximum adsorption capacity of copper onto grafted Luffa cylindrica fiber was found to be 14.23 mg/g with best fit for Langmuir adsorption isotherm. The values of thermodynamic parameters such as enthalpy change, ∆H (-0.823 kJ/mol), entropy change, ∆S (-9.35 J/molK) and free energy change, ∆G (−1.56 kJ/mol) were also calculated. Adsorption process was found spontaneous and exothermic in nature. Finally, the luffa cylindrica has been evaluated by FTIR, MO and x-ray diffraction in order to determine if the biosorption process modifies its chemical structure and morphology, respectively.

The aim of the research is to study the properties of fiber reinforced self–compacting (FRSCC) and to develop the expert system/computer program of mix proportion for calculating the steel fiber content and pozzolanic replacement that can be applied to investigate the compressive strength of FSCC mix. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=self-compacting%20concrete" title="self-compacting concrete">self-compacting concrete</a>, <a href="https://publications.waset.org/abstracts/search?q=silica%20fume" title=" silica fume"> silica fume</a>, <a href="https://publications.waset.org/abstracts/search?q=steel%20fiber" title=" steel fiber"> steel fiber</a>, <a href="https://publications.waset.org/abstracts/search?q=fresh%20taste" title=" fresh taste"> fresh taste</a> </p> <a href="https://publications.waset.org/abstracts/1321/performance-of-fiber-reinforced-self-compacting-concrete-containing-different-pozzolanic-materials" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/1321.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">574</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">1577</span> Using Crowd-Sourced Data to Assess Safety in Developing Countries: The Case Study of Eastern Cairo, Egypt</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mahmoud%20Ahmed%20Farrag">Mahmoud Ahmed Farrag</a>, <a href="https://publications.waset.org/abstracts/search?q=Ali%20Zain%20Elabdeen%20Heikal"> Ali Zain Elabdeen Heikal</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohamed%20Shawky%20Ahmed"> Mohamed Shawky Ahmed</a>, <a href="https://publications.waset.org/abstracts/search?q=Ahmed%20Osama%20Amer"> Ahmed Osama Amer</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Crowd-sourced data refers to data that is collected and shared by a large number of individuals or organizations, often through the use of digital technologies such as mobile devices and social media. The shortage in crash data collection in developing countries makes it difficult to fully understand and address road safety issues in these regions. In developing countries, crowd-sourced data can be a valuable tool for improving road safety, particularly in urban areas where the majority of road crashes occur. This study is -to our best knowledge- the first to develop safety performance functions using crowd-sourced data by adopting a negative binomial structure model and the Full Bayes model to investigate traffic safety for urban road networks and provide insights into the impact of roadway characteristics. Furthermore, as a part of the safety management process, network screening has been undergone through applying two different methods to rank the most hazardous road segments: PCR method (adopted in the Highway Capacity Manual HCM) as well as a graphical method using GIS tools to compare and validate. Lastly, recommendations were suggested for policymakers to ensure safer roads. <p class="card-text"><strong>Keywords:</strong> <a
