The module is verified through comparing the result with that obtained from MATLAB tools. The design runs at a frequency of 36.3 MHz on Virtex-5 Xilinx FPGA. The key size is designed to be 1024-bit to achieve high security for the passport information. The whole design is achieved through VHDL design entry which makes it a portable design and can be directed to any hardware platform. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=RSA" title="RSA">RSA</a>, <a href="https://publications.waset.org/abstracts/search?q=VHDL" title=" VHDL"> VHDL</a>, <a href="https://publications.waset.org/abstracts/search?q=FPGA" title=" FPGA"> FPGA</a>, <a href="https://publications.waset.org/abstracts/search?q=modular%20multiplication" title=" modular multiplication"> modular multiplication</a>, <a href="https://publications.waset.org/abstracts/search?q=modular%20exponential" title=" modular exponential"> modular exponential</a> </p> <a href="https://publications.waset.org/abstracts/4249/fpga-implementation-of-rsa-encryption-algorithm-for-e-passport-application" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/4249.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">389</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">292</span> Investigation of the Aerodynamic Characteristics of a Vertical Take-Off and Landing Mini Unmanned Aerial Vehicle Configuration</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Amir%20Abdelqodus">Amir Abdelqodus</a>, <a href="https://publications.waset.org/abstracts/search?q=Mario%20Shehata"> Mario Shehata</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The purpose of the paper is to model and evaluate the aerodynamic coefficients and stability derivatives of a Vertical, Take-off and Landing Unmanned Aerial Vehicle configuration (VTOL UAV), which is a fixed wing UAV and a quad-copter hybrid capable of both vertical and conventional take-off and/or landing. The aerodynamic analysis of this configuration was carried out using CFD commercial package Ansys Fluent. Also, the aerodynamic coefficients for the case of the UAV without the quad-copter is carried out analytically using MATLAB programmed codes, and the resulting data is verified using Lifting Line Theory and potential method programs.

The effect of inlet inclination angle has been investigated with Reynolds number range (3000 – 4000) and Pr=0.71. The heat exchanger is fabricated from copper concentric inner tube with a length of 750 mm. The effects of hot to cold inlet flow rate ratio (MH/MC), Reynolds's number and of inlet inclination angle of 30°, 45°, 60° and 90° are considered. The results showed that the numerical prediction shows a good agreement with experimental measurement.

Quantitative research was used in this constructivist research. A case-based study was conducted to assess the structures of positive attitudes and expectations in the context of quality improvement. A survey based on expert opinions was analyzed among construction organizations/companies operating in the construction industry in Pakistan. The financial strength, management structure and construction experience of the construction companies formed the basis of their selection. A good concept is visible at the project level and is seen as the most valuable part of the construction project. Each quality improvement technique was expected to increase the user's profits by improving the efficiency of the construction project. The Survey is useful for construction professionals to evaluate current construction concepts and expectations for the application of quality improvement techniques in construction projects. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=correlation%20analysis" title="correlation analysis">correlation analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=lean%20construction%20tools" title=" lean construction tools"> lean construction tools</a>, <a href="https://publications.waset.org/abstracts/search?q=lean%20construction" title=" lean construction"> lean construction</a>, <a href="https://publications.waset.org/abstracts/search?q=logistic%20regression%20analysis" title=" logistic regression analysis"> logistic regression analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=risk%20management" title=" risk management"> risk management</a>, <a href="https://publications.waset.org/abstracts/search?q=safety%20construction%20quality" title=" safety construction quality"> safety construction quality</a>, <a href="https://publications.waset.org/abstracts/search?q=expectation" title=" expectation"> expectation</a>, <a href="https://publications.waset.org/abstracts/search?q=improvement" title=" improvement"> improvement</a>, <a href="https://publications.waset.org/abstracts/search?q=perception" title=" perception"> perception</a> </p> <a href="https://publications.waset.org/abstracts/185149/the-effect-of-artificial-intelligence-on-construction-development" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/185149.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">59</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">289</span> Effects of Unfamiliar Orthography on the Lexical Encoding of Novel Phonological Features</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Asmaa%20Shehata">Asmaa Shehata</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Prior research indicates that second language (L2) learners encounter difficulty in the distinguishing novel L2 contrasting sounds that are not contrastive in their native languages. L2 orthographic information, however, is found to play a positive role in the acquisition of non-native phoneme contrasts. While most studies have mainly involved a familiar written script (i.e., the Roman script), the influence of a foreign, unfamiliar script is still unknown. Therefore, the present study asks: Does unfamiliar L2 script play a role in creating distinct phonological representations of novel contrasting phonemes? It is predicted that subjects’ performance in the unfamiliar orthography group will outperform their counterparts’ performance in the control group. Thus, training that entails orthographic inputs can yield a significant improvement in L2 adult learners’ identification and lexical encoding of novel L2 consonant contrasts. Results are discussed in terms of their implications for the type of input introduced to L2 learners to improve their language learning. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Arabic" title="Arabic">Arabic</a>, <a href="https://publications.waset.org/abstracts/search?q=consonant%20contrasts" title=" consonant contrasts"> consonant contrasts</a>, <a href="https://publications.waset.org/abstracts/search?q=foreign%20script" title=" foreign script"> foreign script</a>, <a href="https://publications.waset.org/abstracts/search?q=lexical%20encoding" title=" lexical encoding"> lexical encoding</a>, <a href="https://publications.waset.org/abstracts/search?q=orthography" title=" orthography"> orthography</a>, <a href="https://publications.waset.org/abstracts/search?q=word%20learning" title=" word learning"> word learning</a> </p> <a href="https://publications.waset.org/abstracts/55226/effects-of-unfamiliar-orthography-on-the-lexical-encoding-of-novel-phonological-features" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/55226.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">256</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">288</span> Improvement of Data Transfer over Simple Object Access Protocol (SOAP)</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Khaled%20Ahmed%20Kadouh">Khaled Ahmed Kadouh</a>, <a href="https://publications.waset.org/abstracts/search?q=Kamal%20Ali%20Albashiri"> Kamal Ali Albashiri</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper presents a designed algorithm involves improvement of transferring data over Simple Object Access Protocol (SOAP).

This paper reports in an effort made to optimize the orders quantities of spare parts by improving the method of forecasting the demand. The study focuses on equipment that has frequent spare parts purchase orders with uncertain demand. The pattern of the demand considers a lumpy pattern which makes conventional forecasting methods less effective. A comparison was made by benchmarking various methods of forecasting based on experts’ criteria to select the most suitable method for the case study. Three actual data sets were used to make the forecast in this case study. Two neural networks (NN) approaches were utilized and compared, namely long short-term memory (LSTM) and multilayer perceptron (MLP). The results as expected, showed that the NN models gave better results than traditional forecasting method (judgmental method).

However, little researches in this field are available regarding female sexual function. Aim: To investigate the possible link between polymorphism in the CAG repeat of AR gene and female sexual function in a sample of the Egyptian population. Materials and methods: 500 Egyptian married females completed a questionnaire regarding sociodemographic, reproductive, and sexual data. AR CAG repeat length was analyzed for those having female sexual dysfunctions (FSD) using real-time PCR. Results: The most sensitive domain to AR CAG repeat length was the orgasm domain that showed significant positive correlations with short allele (p=0.001), long allele (p=.015), biallellic mean (p=.000), and X weighted biallelic mean (p=.000). The satisfaction domain had significant positive correlations with the biallelic mean (p=.035), and the X weighted biallelic mean (p=. 032). However, the pain domain was of significant negative correlations with AR polymorphism of short allele (p=.002), biallelic mean (p=.013), and X weighted biallelic mean (p = . 011). Conclusions: AR polymorphism could represent a non-negligible aspect in female sexual function. The lower AR CAG repeat polymorphism was of significant impact on FSD, affecting mainly female orgasm followed by pain disorders that finally reflected On her sexual satisfaction. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=female%20sexual%20dysfunction" title="female sexual dysfunction">female sexual dysfunction</a>, <a href="https://publications.waset.org/abstracts/search?q=androgen%20receptor" title=" androgen receptor"> androgen receptor</a>, <a href="https://publications.waset.org/abstracts/search?q=CAG%20repeat%20polymorphism" title=" CAG repeat polymorphism"> CAG repeat polymorphism</a>, <a href="https://publications.waset.org/abstracts/search?q=androgen" title=" androgen"> androgen</a> </p> <a href="https://publications.waset.org/abstracts/142676/cag-repeat-polymorphism-of-androgen-receptor-and-female-sexual-functions-in-egyptian-female-population" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/142676.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">182</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">278</span> Evaluation of Digital Assessment of Anal Sphincter Muscle Strength</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Emmanuel%20Kamal%20Aziz%20Saba">Emmanuel Kamal Aziz Saba</a>, <a href="https://publications.waset.org/abstracts/search?q=Gihan%20Abd%20El-Lateif%20Younis%20El-Tantawi"> Gihan Abd El-Lateif Younis El-Tantawi</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohammed%20Hamdy%20Zahran"> Mohammed Hamdy Zahran</a>, <a href="https://publications.waset.org/abstracts/search?q=Ibrahim%20Khalil%20Ibrahim"> Ibrahim Khalil Ibrahim</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohammed%20Abd%20El-Salam%20Shehata"> Mohammed Abd El-Salam Shehata</a>, <a href="https://publications.waset.org/abstracts/search?q=Hussein%20Al-Moghazy%20Sultan"> Hussein Al-Moghazy Sultan</a>, <a href="https://publications.waset.org/abstracts/search?q=Medhat%20Mohamed%20Anwar"> Medhat Mohamed Anwar</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Examination of the external anal sphincter muscle strength of voluntary contraction is essential in initial assessment and assessment of efficacy of rehabilitation of patients with faecal incontinence (FI) and obstructed defecation (OD). The present study was conducted to evaluate the digital assessment of the external anal sphincter muscle strength of voluntary contraction by using Modified Oxford Scale (MOS) in comparison to anal manometry squeeze pressure. The present cross-sectional study included 65 patients. There were 40 patients (61.5 %) with FI and 25 patients (38.5 %) with OD. All patients were subjected to history taking, clinical examination including assessment of the external anal sphincter muscle strength of voluntary contraction by using MOS and anal manometry (mean squeeze pressure and maximal squeeze pressure). There was a statistically significant positive correlation between MOS and anal manometry squeeze pressures including mean squeeze pressure and maximal squeeze pressure among FI group and OD group. In conclusion, assessment of the external anal sphincter muscle strength of voluntary contraction by using MOS is a valid method and can substitute anal manometry assessment. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=anal%20manometry" title="anal manometry">anal manometry</a>, <a href="https://publications.waset.org/abstracts/search?q=external%20anal%20sphincter%20muscle" title=" external anal sphincter muscle"> external anal sphincter muscle</a>, <a href="https://publications.waset.org/abstracts/search?q=Modified%20Oxford%20Scale" title=" Modified Oxford Scale"> Modified Oxford Scale</a>, <a href="https://publications.waset.org/abstracts/search?q=muscle%20strength" title=" muscle strength"> muscle strength</a> </p> <a href="https://publications.waset.org/abstracts/32483/evaluation-of-digital-assessment-of-anal-sphincter-muscle-strength" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/32483.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">416</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">277</span> Tabu Search Algorithm for Ship Routing and Scheduling Problem with Time Window</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Khaled%20Moh.%20Alhamad">Khaled Moh.

The World Health Organization acknowledges vaccine hesitancy as the society’s maximum risk to people's health protection, especially in little and moderate-revenue nations. Social media is strong in observing audience behaviors and evaluating the circulation, which would supply useful data for strategy makers. It has a significant function in spreading facts during the pandemic, it could assist to boost protective manners. The objective of this study is to determine the effects of social media exposure on vaccine hesitancy. Data were collected using a survey in a form of a structured questionnaire conducted during December 2021- January 2022 using convenient sampling techniques (680) in Egypt and the United Arab Emirates. The results revealed that there was a significant relationship between the high exposure to social media and the refusal of the Covid19 vaccine also, the percentage of the refusal of the vaccine is higher in Egypt, however, UAE forced people to take the vaccine. Furthermore, public attitudes toward COVID-19 vaccination vary from gender and region. In conclusion, policymakers must adjust their policies through the use of social media to immediate actions to vaccine-related news to support vaccination approval. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=COVID-19" title="COVID-19">COVID-19</a>, <a href="https://publications.waset.org/abstracts/search?q=hesitancy" title=" hesitancy"> hesitancy</a>, <a href="https://publications.waset.org/abstracts/search?q=social%20media" title=" social media"> social media</a>, <a href="https://publications.waset.org/abstracts/search?q=vaccine" title=" vaccine"> vaccine</a> </p> <a href="https://publications.waset.org/abstracts/147964/the-impact-of-social-media-exposure-on-covid-19-vaccine-hesitancy-a-comparative-study-on-the-public-in-egypt-and-the-united-arab-emirates" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/147964.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">139</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">273</span> The Works of Ibrahim Eissa: A Controversy</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Malak%20Khaled%20Hosny">Malak Khaled Hosny</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The paper inspects Ibrahim Eissa, a famous Egyptian writer and TV persona, and his literary and film works. Having faced threats of persecution and assassination, Eissa is a controversial figure in Egyptian media, and his works always pose a trigger of outrage and conversation. His book The Preacher, his movie The Guest, and his TV show Faten Amal Harby all led to some controversy unfolding in Egyptian society, and all led to conversations erupting in Egyptian households and on social media platforms. Through a close reading of his written work and an analytic watch of his work on-screen, the paper delves into the details of the intentions behind and the repercussions of Ibrahim Eissa's work. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=censorship" title="censorship">censorship</a>, <a href="https://publications.waset.org/abstracts/search?q=film" title=" film"> film</a>, <a href="https://publications.waset.org/abstracts/search?q=literature" title=" literature"> literature</a>, <a href="https://publications.waset.org/abstracts/search?q=religion" title=" religion"> religion</a> </p> <a href="https://publications.waset.org/abstracts/175686/the-works-of-ibrahim-eissa-a-controversy" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/175686.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">106</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">272</span> Simultaneous Determination of Cefazolin and Cefotaxime in Urine by HPLC</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Rafika%20Bibi">Rafika Bibi</a>, <a href="https://publications.waset.org/abstracts/search?q=Khaled%20Khaladi"> Khaled Khaladi</a>, <a href="https://publications.waset.org/abstracts/search?q=Hind%20Mokran"> Hind Mokran</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohamed%20Salah%20Boukhechem"> Mohamed Salah Boukhechem</a> </p> <p class="card-text"><strong>Abstract:</strong></p> A high performance liquid chromatographic method with ultraviolet detection at 264nm was developed and validate for quantitative determination and separation of cefazolin and cefotaxime in urine, the mobile phase consisted of acetonitrile and phosphate buffer pH4,2(15 :85) (v/v) pumped through ODB 250× 4,6 mm, 5um column at a flow rate of 1ml/min, loop of 20ul.

These oils can successfully replace the antibiotics. So, the microorganisms show their inefficiencies resistant for the antibiotics. For this reason, we study the physicochemical analysis and antimicrobial activity of the essential oil of Daucus carota. The extraction is done by steam distillation of water which brought us a very significant return of 4.65%. The analysis of the essential oil is performed by GC/MS and has allowed us to identify 32 compounds in the oil of D. carota flowering tops of Bouira.

This method of debugging enables developers and maintenance engineers to replace a set of existing resources such as images, server side scripts, cascading style sheets with another set of resources per web session. The new resources will only be active in the debug session and other sessions will not be affected. This methodology will help developers in tracing defects, especially those that appear only in production environments and in exploring the behaviour of the system.

We employ a new methodology: TVP FAVAR model with stochastic volatility. We use a large dataset of 111 major U.S variables from 1959:m1 to 2016:m12. The results show that Bitcoin shocks significantly impact the U.S. economy. This significant impact is pronounced in a volatile and increasing U.S economy. The Bitcoin has a positive relationship on the U.S real activity, and a negative one on U.S prices and interest rates.
