An enhanced electrocoagulation process for the removal of fe and mn from municipal wastewater using dielectrophoresis (Dep)
( MDPI AG , 2021 , Article)In this study the removal of Fe and Mn from primary treated municipal wastewater using a new electrode configuration in electrocoagulation was evaluated. The used electrode configuration induced a dielectrophoretic (DEP) ... -
Analysis of gap parameters for the estimation of single lane roundabouts' capacity in the State of Qatar
( Elsevier B.V. , 2021 , Conference Paper)Entry capacity is an important parameter for evaluating the roundabout performance. In general, entry capacity is influenced by three gap parameters: critical gap, follow-up time and minimum headway of circulating vehicles. ... -
Autonomous vehicles between anticipation and apprehension: Investigations through safety and security perceptions
( Elsevier Ltd. , 2021 , Article)Due to the ongoing enormous infrastructural developments and car ownership culture in Qatar, it could be one of those countries to introduce Autonomous Vehicles (AV) technology at the early stages. Therefore, this study ... -
Crowd Evacuation through Crossing Configurations: Effect of Crossing Angles and Walking Speeds on Speed Variation and Evacuation Time
( Multidisciplinary Digital Publishing Institute (MDPI) , 2022 , Article)The design of safe and efficient pedestrian facilities necessitates the knowledge of complex human movements, such as intersecting pedestrian streams, under different conditions. This study aims to experimentally investigate ... -
Effects of current, electrodes spacing and operational time on the removal of heavy metals from primary treated municipal wastewater using dielectrophoresis.
( Qatar University Press , 2020 , Poster)Electrocoagulation (EC) is an emerging technology that has been used to treat heavy metals from different kinds of wastewater. This paper discusses the effects of inducing Dielectrophoretic (DEP) force in EC system for the ... -
An Enhanced Electrocoagulation Process for The Removal Of Fe and Mn from Municipal Wastewater Using Dielectrophoresis (DEP)
(2020 , Master Thesis)This study evaluates the removal efficiency of Fe and Mn from primary treated municipal wastewater using new electrodes configuration in electrocoagulation (EC) process. The used electrodes configuration generates a ... -
A novel agent-based framework for evaluating pedestrian safety at unsignalized mid-block crosswalks
( Elsevier Ltd. , 2021 , Article)A critical safety problem in road networks is the conflicts on unsignalized crosswalks. Thus, a proactive approach to assess pedestrian safety performance is required. Simulating the microscopic road user behavior in a ... -
Road safety status during COVID-19 pandemic: exploring public and road safety expert’s opinions
( Taylor & Francis , 2022 , Article)The main objective of this study is to investigate the status of traffic safety and the public perception of traffic safety during the during COVID-19 pandemic. Three different data sets are used in this study: road crash ... -
The influence of aeration scheme and aeration rate on the permeate flux for wastewater treatment using membrane bioreactors: Experimental and artificial neural network modeling
( Desalination Publications , 2021 , Article)In this paper, the effect of time, aeration scheme, aeration rate, and mixed liquor suspended solid (MLSS) concentration on the permeate flux in membrane bioreactors have been studied. Aeration rates of 0.5, 1.0, and 1.5 ... -
Unlocking the application potential of electrocoagulation process through hybrid processes
( Elsevier , 2021 , Article Review)Electrocoagulation (EC) has attracted attention during the recent years due to its ease of use and high removal rate of organic and inorganic pollutants. It was found that using EC as a pretreatment process can decrease ...
