Development of a mobile application for manual traffic counts
( EDP Sciences , 2017 , Conference Paper)The use of technology in performing traffic counts has become widely used by many transportation agencies and private sectors. Different technologies have been employed to perform such counts, such as inductive loops, image ... -
Development of a three-dimensional staged volume loss tunnelling method in the centrifuge
( ICE Publishing , 2019 , Article)Conventional assessment of tunnelling-induced settlement focuses primarily on transverse profiles given the transitional nature of the longitudinal settlement profile. This approach thus relies on the commonly made assumption ... -
Development of Digitalization Road Map for Healthcare Facility Management
( IEEE , 2022 , Article)Effective Healthcare Facility Management (HFM) remain a crucial concern for high quality built healthcare sectors, both in the public and private areas. The anticipated resource efficiencies, complex systems, and maintenance ... -
Development of high-strength lightweight non-autoclaved aerated concrete
( ICE Publishing , 2020 , Article)Six concrete mixes with different proportions of various pozzolanic materials were investigated for the development of high-strength non-autoclaved aerated concrete (NAAC). Fly ash and slag were used as partial cement ... -
Development of Warm Mix Asphalt with the Aid of Microstructural Characterization
( Qatar Univesrity Press , 2020 , Conference Paper)The polymer-modified asphalt (PMA) reveals different types of advantageous properties depending on the type of polymer. However, one of the unwanted changes in PMA is the required higher temperature for mixing and compaction. ... -
Development, validation, and application of School Audit Tool (SAT): An effective instrument for assessing traffic safety and operation around schools
( MDPI AG , 2019 , Article)There is a need for a reliable school audit tool with well-defined scales to convert qualitative evaluation of existing school sites into a quantitative assessment in order to help public agencies to improve schools' safety ... -
Diaphragm shear strength and stiffness of aluminum roof panel assemblies
( Elsevier Ltd , 2016 , Article)A diaphragm is an assembly of planar structural elements interconnected to each other to provide in-plane bracing system and transmit in-plane forces. The diaphragm geometry, supporting frame, type of the panel profiles, ... -
Different FRCM systems for shear-strengthening of reinforced concrete beams
( Elsevier Ltd , 2017 , Article)This paper presents the results of an extensive experimental study on the efficacy of different fabric-reinforced cementitous matrix (FRCM) systems for the strengthening of reinforced concrete (RC) beams, which are critical ... -
Dilution of seawater using dewatered construction water in a hybrid forward osmosis system
( Elsevier Ltd , 2018 , Article)In this study, dewatered construction water was used for the first time as the feed solution in a combined pretreatment-forward osmosis process to dilute seawater (i.e. draw solution) for further desalination. It was found ... -
Discrepancy in the Critical State Void Ratio of Poorly Graded Sand due to Shear Strain Localization
( American Society of Civil Engineers (ASCE) , 2020 , Article)The critical state (CS) concept is a theoretical framework that models the constitutive behavior of soils, including sand and other granular materials. It supports the notion of a unique postfailure state, where the soil ... -
Discrete event simulation for sustainable batch production in food processing
( Dime University of Genoa , 2016 , Conference Paper)In a world faced with depleting resources and hazardous biodegradable food wastes, an efficient planning for the food processing operation is crucial to avoid the adverse potential impact of excess food production. This ... -
Discrete particle translation gradient concept to expose strain localisation in sheared granular materials using 3D experimental kinematic measurements
( ICE Publishing , 2018 , Article)It is well known that the constitutive behaviour of granular materials is influenced by strain localisation into zones of intensive shearing, known as shear bands. The failure mode of specimens tested under axisymmetric ... -
Disruption factor of asphalt mixtures
( Taylor & Francis , 2012 , Article)Typically, aggregate gradation is selected to meet Superpave mix design specification; however, many Superpave mixtures have exhibited deficient field performance. The porosity of the dominant aggregate size range (DASR), ... -
Does Pedestrian Penalty Affect Pedestrian Behavior? A Case of State of Qatar
( Elsevier , 2021 , Article)Crashes involving pedestrians are a major concern for authorities in many developed and developing countries. To refrain pedestrians from illegal or unsafe road behavior, authorities introduced three pedestrian penalties ... -
