Sagittal plane waves in infinitely periodic multilayered composites composed of alternating viscoelastic and elastic solids
( American Society of Mechanical Engineers (ASME) , 2018 , Article)In order to design phononic crystals whose band-gaps are located in low-frequency ranges, researchers commonly adopt low stiffness polymeric materials as key constituents and exploit the high impedance mismatch between ... -
Scales of flows: Qatar and the urban legacies of mega events
( Emerald , 2013 , Article)In 2022, Qatar will become the first Middle Eastern and Arab country to host such an important Mega-Event as the FIFA World Cup. Global cultural and sporting Mega Events have driven the urban transformation of cities such ... -
Seismic Assessment of Existing Lowrise and Midrise Reinforced Concrete Buildings Using the 2014 Qatar Construction Specification
( American Society of Civil Engineers(ASCE) , 2018 , Article)Qatar is considered to have predominantly low seismic activity despite being close to some of the most active seismic zones in the world, including the Zagros thrust belt. However, the strong earthquakes that have recently ... -
Self-ChakmaNet: A deep learning framework for indigenous language learning using handwritten characters
( Elsevier , 2023 , Article)According to UNESCO's Atlas of the World's Languages in Danger, 40% of the languages today are counted as endangered in the future. Indigenous languages are endangered because of the less availability of interactive learning ... -
Self-organizing maps for structural damage detection: A novel unsupervised vibration-based algorithm
( American Society of Civil Engineers (ASCE) , 2016 , Article)The study presented in this paper is arguably the first study to use a self-organizing map (SOM) for global structural damage detection. A novel unsupervised vibration-based damage detection algorithm is introduced using ... -
Self-Report and Observational Assessment and Investigation of Seat Belt Use Among Young Drivers and Passengers: The Case of Qatar
( Springer Berlin Heidelberg , 2018 , Article)Young drivers have the lowest rate of seat belt use among all age groups. The objective of this study was to investigate and assess the seat belt use behavior of young drivers by means of various methods, including ... -
Sensing and monitoring for stadium structures: A review of recent advances and a forward look
( Frontiers Media S.A. , 2017 , Article Review)Stadiums like those used for sporting or concert events are distinct from other civil engineering structures due to several different characteristics. Some challenges mainly originate from the interaction with the human ... -
Sensitivity analysis and genetic algorithm-based shear capacity model for basalt FRC one-way slabs reinforced with BFRP bars
( Elsevier , 2023 , Article)Fiber-reinforced polymer (FRP) composites are increasingly used in concrete structures owing to their superior corrosion resistance. However, FRP-reinforced concrete (RC) structures exhibit less ductile response compared ... -
Settlement of axially loaded piles entirely embedded in rock - analytical and experimental study
( Taylor and Francis , 2012 , Article)Finite element analysis was performed to study the settlement behaviour of axially loaded piles entirely embedded in nonhomogenous rock. The elastic modulus of the rock mass was taken to increase linearly along the pile ... -
Severity analysis of red-light-running-related crashes using structural equation modeling
( Taylor and Francis Inc. , 2019 , Article)The study investigated factors affecting the severity of red-light-running (RLR) -related crashes by means of crash records from the State of Florida (US). Previous studies have attempted to incorporate road, driver, and ... -
