Capacity Analysis of Single-Lane Roundabouts in The State of Qatar
(Civil Engineering, 2020 , Master Thesis)
This master thesis presents capacity analysis of Single-Lane roundabouts in the State of Qatar. The aim of this paper is to update Qatar highway manual, by developing a new capacity model using empirical data collected ...
Factors Influencing the Mechanical Properties of Geopolymer Mortar Made of Fly Ash
(Civil Engineering, 2020 , Master Thesis)
Geopolymerization is a process where silica and alumina rich source materials turns into excellent binding materials by the aid of alkali solutions. Fly ash class F mainly consists of alumina and silica. Compressive strength ...
Fabrication of Fouling Resistant Ti3C2Tx(MXene) Cellulose Acetate Nanocomposite Membrane for Forward Osmosis Application
(Civil Engineering, 2020 , Master Thesis)
Forward Osmosis (FO) is one of the promising technologies that can be used to combat growing water scarcity. However, FO membrane fouling hinders the widespread application of this technology by significantly reducing the ...
Development of Variable Message Sings Strategies for Traffic Management at Work Zones
(Civil Engineering, 2020 , Master Thesis)
Work zones are defined as road sections of which different activities such as road construction or maintenance take place. In most work zones, road alignments are different than the pre-work periods. Therefore, speed limits ...
Examining Preference For Autonomous Vehicle (Av) Among Qatari Residents
(Civil Engineering, 2020 , Master Thesis)
Because of growing body of researches that predict the autonomous vehicles to be the future mode of transport. It is important to investigate the preference of Autonomous vehicles among Qatari citizens for fast developing ...
Sustainable Concrete Using Seawater, Recycled Aggregates, and Non Corrosive Reinforcement
(Civil Engineering, 2020 , Dissertation)
Using seawater and recycled concrete aggregate (RCA) in a concrete mix is potentially advantageous from a sustainability perspective. However, the high chloride levels expected in such a concrete mix demands the use of ...
Micromodel Study on Colloid Retention and Mobilization under different Geo-Chemical Conditions during Single and Two-Phase Flow
(Civil Engineering, 2020 , Dissertation)
Understanding the transport of colloids and colloid-facilitated transport of contaminants is essential for efficient cleanup and remediation processes. Various factors and mechanisms contributing to their retention in the ...
A Comparative Traffic Noise Study between Signalized Intersections and Roundabouts
(Civil Engineering, 2020 , Master Thesis)
This study presents a comparative traffic noise study done between signals and
roundabouts in Doha, Qatar. Traffic noise and volume data were collected at four
signals (two 2-lane and two 3-lane) and four roundabouts ...
Shear Behavior of Green Concrete Beams Reinforced with Basalt FRP Bars and Stirrups.
(Civil Engineering, 2020 , Master Thesis)
The Reinforced concrete structures when exposed to a harsh environment it will be susceptible to the corrosion of steel reinforcement and shall lead to deterioration process. Consequently, the service lifetime of the ...
Experimental and Theoretical Investigation on Bond Behavior of Tensile Lap Spliced Basalt Fiber Reinforced Polymer Bars in High Strength Concrete Beams
(Civil Engineering, 2020 , Master Thesis)
Basalt fiber reinforced polymer (BFRP) reinforcements are a possible replacement for corroding conventional steel bars. BFRP bars tension lap splices are necessary due to construction stoppages and limitations on rebar ...
