Impact of Pore Morphology on Colloid Migration at Variable Saturation Levels of Natural Porous Media
( Qatar University Press , 2023 , Conference)The migration of colloids within porous media has a critical impact on many important industrial processes such as oil production and groundwater recharge. Colloids can clog the pore space and hence impair the permeability ... -
Efficient Turbidity Removal Using a New Gel Filtration Process
( Qatar University Press , 2023 , Conference)The removal of turbidity is a prime objective in the treatment of seawater, especially in the production of potable water. The water turbidity exists because of the colloidal particles or large-weight molecules that remain ... -
Investigation of factors affecting turn signal usage at modern roundabouts in State of Qatar
( Informa UK Limited - Taylor & Francis , 2023 , Article)Drivers are expected to use turn signals to indicate other drivers of their intentions of taking turns, lane changing, merging or diverging indicating safe driving behaviour. This study investigated the rates of turn signal ... -
Lane-based analysis of the saturation flow rate considering traffic composition
( Informa UK Limited - Taylor & Francis , 2023 , Article)Saturation flow rate (SFR) is an essential metric for estimating the capacities of signalized intersections. Many factors, including traffic composition, configuration and geometry of the intersection, and driver behavior, ... -
Fuel consumption at signalized intersections: Investigating the impact of different signal indication settings
( Elsevier Ltd , 2023 , Article)The fuel consumption of vehicles depends on various factors including vehicle design, driving style, traffic management, and road design. Many manufacturers have been developing efficient and smart vehicles, which contributes ... -
The Challenges and Future Aspirations of Implementing Global Sustainability Assessment System (GSAS) in the Urban Facilities of Mega Sport Events [MSEs] in Qatar
( Qatar University Press , 2023 , Conference)Sports facilities are built for a specific function and purpose. Once the demand for such purpose no longer exists, it is important to know how both the buildings and the city will adapt to the existence of such megastructures ... -
Conceptual Framework for Planning Urban Roadside Vegetation to Enhance Air Quality for Roadside Users
( Qatar University Press , 2023 , Conference)Vegetation is known for enhancing air quality. However, vegetation on urban roads can either increase or decrease exposure to air pollutants. The health of pedestrians and cyclists is particularly of great concern since ... -
The Impact of Land Mix-use on Inhabitants’ Social Wellbeing in the Qatari Neighbourhoods
( Qatar University Press , 2023 , Conference)Health and wellbeing have been key considerations in designing sustainable environments. However, most research on built environments and wellbeing has been conducted in Western communities, with very little research in ... -
Cultural Heritage Tourism as a Catalyst for Urban Regeneration: Case of the Doha Historic Center in Qatar
( Qatar University Press , 2023 , Conference)Heritage and tourism have become during the last two decades dynamic areas of development in the world. The idea of heritage is crucial to the critical decision-making process as to how irreplaceable resources are to be ... -
Built Environment Attributes and Walking Patterns: A Case Study of Abu Dhabi Downtown
( Qatar University Press , 2023 , Conference)Walkability is crucial in sustainable urban design. Our understanding on the walkability in cities in hot and arid climate needs to be improved due to shortage of our knowledge and previous studies about this. Thus, this ... -
Highly sensitive humidity sensor based on cadmium selenide quantum dots-polymer composites: synthesis, characterization, and effect of UV/ozone treatment
( Springer , 2023 , Article)This work describes the rational design of thin film-based cadmium selenide quantum dots (CdSe) mixed with conductive polyvinylidene fluoride (PVDF), inducing PVDF-CdSe composite for potential resistive humidity-sensing ... -
