Research ArticleOpen accessIn the author namesAbnormalities in Ultrasonic (C-Scan) Images of Composite Structures: Impact Damaged Versus Hole DamagedMahmoud Zaki IskandaraniThis paper is about applying image processing to detect different types and levels of damage in composite structures using in C-scan images produced by ultrasonic testing. This method plays an important role as it can detect any discontinuities or flaws in the specimen. To analyze such critical image in an, automated inspection environment an image processing method that correlates Threshold … …Journal of Computer Science, Vol. 15, Issue 7 · 23 Jul 2019 · 8,237 accessesView PDFCite
Research ArticleOpen accessIn the author namesCertain Contributions in Traffic Engineering Based on Software-Defined Networking TechnologyAs'ad Mahmoud As'ad AlnaserThe paper addresses the traffic engineering in Software-Defined Networks (SDN). A brief analysis of the features of the SDN organization, which allows to increase the Traffic Engineering (TE) efficiency, is given. The viability of using multipath routing with TE is substantiated. Taking into account the features of the SDN technology, a modified TE method, which allows to reduce the time … …Journal of Computer Science, Vol. 15, Issue 7 · 9 Jul 2019 · 7,710 accessesView PDFCite
Research ArticleOpen accessIn the author namesData Exploration in the Supermarket System to Study the Behavior of the Jordanian ConsumersKhaled Aldiabat, Mahmoud Ali Al-Rousan, Ali A. AlzoubiThe study aimed to identify the extent of using data exploration in the supermarket system to study the behavior of the Jordanian consumers and the extent of using data exploration in commercial shops in Jordan. The study concluded that data exploration in the supermarket system is not used to study the behavior of the Jordanian consumers regarding the disclosure of … …Journal of Computer Science, Vol. 15, Issue 5 · 24 May 2019 · 7,441 accessesView PDFCite

For this purpose a parasitological study was designed, which used fecal egg count reduction test Two hundred seventy ewes were enrolled in this study, twenty … …American Journal of Animal and Veterinary Sciences, Vol. 14, Issue 2 · 14 May 2019 · 8,061 accessesView PDFCite
Research ArticleOpen accessIn the author namesOn Odds Generalized Exponential-Power Lomax DistributionSalwa Mahmoud AssarA new distribution, called odds generalized exponential-power Lomax distribution is suggested for modeling lifetime data. Some structural properties of the new distribution including; quantiles, Rényi entropy, moments and distribution of order statistics are provided. The model parameters of the new distribution are estimated by the maximum likelihood method. Finally, applications to two real data sets are analyzed to illustrate the … …Journal of Mathematics and Statistics, Vol. 14, Issue 1 · 12 Jun 2018 · 7,571 accessesView PDFCite
Research ArticleOpen accessIn the author namesCharacterization of Composite Structure Surface Uniformity using Interval Based Gradient Field Histogram Analysis of Thermographic Images (IGF-HA)Mahmoud Zaki IskandaraniThis paper presents a new approach to composite surface characterization using Image Histogram Analysis as a function of Gradient Field. Image sequences are weighed and combined in order to present a pattern change in the thermal response of a tested composite structure. Reaction Injection Molding samples used and subjected to thermal energy to characterize their surface uniformity and any existing … …Journal of Computer Science, Vol. 14, Issue 6 · 25 May 2018 · 7,977 accessesView PDFCite
Research ArticleOpen accessIn the author namesOn the Security of the Sensor Cloud Security Library (SCSlib)Mohamed Rasslan, Mahmoud Nasreldin, Ghada Elkabbany, Aya ElshobakyNowadays, cloud computing has experienced remarkable growth. Indeed, one of the main challenges of cloud computing is to protect data from different sensor devices during processing and storing. In 2014, Henze et al. proposed the Sensor Cloud Security library (SCSlib) which allows cloud developer to access encrypted sensor data stored in the cloud. SCSLib drawback is that it allows a … …Journal of Computer Science, Vol. 14, Issue 6 · 23 May 2018 · 8,082 accessesView PDFCite

Research ArticleOpen accessIn the author namesComparative Analysis of Skid Resistance for Different Roadway Surface TreatmentsOsama A. Abaza, Tanay Datta Chowdhury, Mahmoud ArafatPavement skid resistance impacts road functionality and can affect user safety and vehicle operation costs. This study was an investigation of the effect of sealcoats on skid resistance. Seven different sealcoats-fog seal, chip seal, slurry seal, sand seal, high-friction seal, cape seal, and glass seal-were lab and field tested. Laboratory samples were further tested in the field on pavement sections. … …American Journal of Engineering and Applied Sciences, Vol. 10, Issue 4 · 10 Nov 2017 · 8,143 accessesView PDFCite
Research ArticleOpen accessIn the author namesAssociation of High-Affinity FcεRI-β intron 2 for IgE Gene Polymorphism and Atopic Diseases in an Algerian PopulationDahbia Ines Dahmani, Ikhlass Haj Salem, Jamila Chakir et al.Atopy is characterized by the production of a high level of IgE in response to common allergens. We examined the RsaI-in2 polymorphism of the FcεRI-β gene and its association with atopic asthma and comorbidity. The study population included 77 atopic asthmatics and 77 non-atopic, non-allergic and non-asthmatic controls. Atopic asthma was confirmed by the skin prick test and by IgE … …OnLine Journal of Biological Sciences, Vol. 17, Issue 4 · 1 Nov 2017 · 7,448 accessesView PDFCite
