Research ArticleOpen accessEvery word in the titleNumerical Study on Coupling Beam Retrofitted Using CFRP and GFRP SheetsSaeideh Hakimi, Rahmat MadandoustOne of the most useful way to resist against earthquake is using coupling beam of steel shear walls. The steel shear wall’s behavior depends on several factors such as stiffness, ductility, strength and so on. But, it has the shear cracks in coupling beam. In this paper, the effect of Carbon Reinforced Fiber Polymer (CFRP) on coupling beams has been … …American Journal of Engineering and Applied Sciences, Vol. 11, Issue 3 · 6 Aug 2018 · 7,723 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleModeling of Reinforced Concrete Frames with Infill Walls Under Cyclic Loading Strengthening with CFRPMojtaba Fallahi, Sajjad Sayyar Roudsari, Mona Haghighifar, Rahmat MadandoostNowadays, using infill isolators in Reinforced Concrete (RC) structures is very common. In earlier research this infill isolators are usually considered as non-structural elements, but in recent researches it was demonstrated that infill has considerable effects on natural period, stiffness, strength and overall behavior of structure specially when it is subjected to seismic ground motions. In this study a one-bay … …American Journal of Engineering and Applied Sciences, Vol. 11, Issue 3 · 6 Jul 2018 · 8,444 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleFinite-Element Numerical Simulation of the Bending Performance of Post-Tensioned Structural Glass Beams with Adhesively Bonded CFRP TendonsChiara Bedon, Christian LouterIn this study, a Finite-Element (FE) numerical investigation is carried out on laminated glass beams with Carbon Fibre Reinforced Polymer (CFRP) adhesively bonded post-tensioning tendons. Taking advantage of past four-point bending experimental test results available in literature, a refined full 3D FE numerical model is calibrated and validated. A key role is given to a multitude of aspects, including the … …American Journal of Engineering and Applied Sciences, Vol. 9, Issue 3 · 27 Sep 2016 · 8,739 accessesView PDFCite
Research ArticleOpen accessIn the keywordsEpidemiological Insights and Case Fatality Analysis of SARS-CoV-2 in Indian States During the First WaveRakesh Kaushik, Nikita et al.Severe Acute Respiratory Syndrome Coronavirus-2 (SARS-CoV-2) has globally spread, causing a significant health crisis. India, with over 157,000 fatalities, ranks third globally in mortality cases. While vaccine development has played a pivotal role in decelerating the virus's spread, understanding the specific factors influencing morbidity and mortality during the first wave remains essential. This retrospective study analyzes data from 28 Indian … …OnLine Journal of Biological Sciences, Vol. 25, Issue 1 · 21 Jan 2025 · 4,308 accessesView PDFCite
Research ArticleOpen accessIn the keywordsCongestion Free Routing in Adhoc NetworksT. Senthil Kumaran, V. SankaranarayananProblem statement: A Mobile Ad-Hoc Network (MANET) is a temporary network; the mobile devices in an ad-hoc network are communicating through wireless links without any pre-existing infrastructure. The one major problem of this network is network congestion, it may take place at any intermediate nodes when data packets are traveling from source to destination. The major problems of congestion or … …Journal of Computer Science, Vol. 8, Issue 6 · 4 Apr 2012 · 7,236 accessesView PDFCite
Research ArticleOpen accessIn the abstractFirst-Degree Polynomial Gradient Approach to Reveal the Severity of COVID-19 Pandemic in Affected CountriesDedy Rahman Wijaya, Anak Agung Gde Agung, Tora Fahrudin, SuryatiningsihCOVID-19 is a new type of Coronavirus (2019-nCoV) which originated from Wuhan in China. Since 11 March 2020, WHO has declared COVID-19 as a pandemic. Currently, it has spread to 175 countries or regions around the world. From day to day, confirmed, recovered and death cases have been reported. This data rapidly changes that indicates an uncertain situation. This uncertain … …Journal of Computer Science, Vol. 17, Issue 2 · 16 Mar 2021 · 7,171 accessesView PDFCite
Research ArticleOpen accessIn the abstractCurrent Advances in Zika Virus Transmission: Urgency for Effective Therapeutics and PreventionYash Raj, Swatantra Kumar, Amrita Haikerwal et al.Global emergence of Zika Virus (ZIKV) with prevalent outbreaks has been reported in numerous countries of South America, Central America and the Caribbean region. According to recent World Health Organization (WHO)-ZIKV situation report, 84 countries/territories/subnational areas represented with established mosquito-borne transmission of ZIKV. As of 10 August 2017, cumulative Zika cases and congenital syndrome associated with Zika virus reported by … …American Journal of Infectious Diseases, Vol. 13, Issue 2 · 2 Oct 2017 · 7,798 accessesView PDFCite
Research ArticleOpen accessIn the abstractEstimation of the Case Fatality Ratio of Middle East Respiratory Syndrome based on Patients' Comorbidities with Application to the MERS-CoV Epidemics in the Republic of Korea, 2015Changhyuck Oh, Seonyeong HwangIn an early stage of the course of the Middle East Respiratory Syndrome Coronavirus (MERS-CoV) outbreak in Korea in 2015, the Centers for Disease Control and Prevention of Korea and several studies reported estimated Case Fatality Ratios (CFRs) that were significantly different. Here, we propose an estimation method based on the commonly quoted naive estimator of CFR utilizing the number … …American Journal of Applied Sciences, Vol. 13, Issue 11 · 14 Nov 2016 · 7,458 accessesView PDFCite
Research ArticleOpen accessIn the abstractNEURO FUZZY BASED PERFORMANCE ANALYSIS OF MULTIBAND ULTRA WIDE BAND ORTHOGONAL FREQUENCY DIVISION MULTIPLEXING SYSTEMG. Joselin Retna Kumar, K. S. ShajiThis study proposes an efficient channel-estimation scheme for Multiband (MB) Orthogonal Frequency Division Multiplexing (OFDM)-based Ultra Wide Band (UWB) communication systems. One of the challenges in wireless system is the frequency selective fading caused due to multipath channel between the transmitter and receiver. The signal bandwidth in broad band cellular wireless systems typically exceeds the coherence bandwidth of the multipath … …Journal of Computer Science, Vol. 10, Issue 8 · 5 Mar 2014 · 6,616 accessesView PDFCite
Research ArticleOpen accessIn the abstractPhysiological Response and Postmolt Performance of Laying Hens Molted by Non-Feed Removal MethodsFariborz Khajali, Saied Karimi, M.R. AkhariOne experiment was conducted to evaluate the physiological response and postmolt performance of laying hens subjected to non-feed removal molting programs. One hundred and eighty 78-week-old Hy-line W36 laying hens were distributed among 45 groups of four birds and located in cages so that mean body weight of each cage was very similar.
