Evaluation of Bond Strength Between Carbon Fiber Reinforced Polymer (CFRP) Composites with Modified Epoxy Resins and Concrete
(
Qatar Univesrity Press
, 2020 , Conference Paper)
Rehabilitation and strengthening of concrete structures are becoming more significant
in civil engineering applications. The use of externally bonded Fiber Reinforced
Polymers (FRP) is one of the methods to strengthen and ...
An Analytical Review of Sustainable Green Buildings in Qatar: Implementations in the Architecture, Engineering and Construction (AEC) Sector
(
Qatar Univesrity Press
, 2020 , Conference Paper)
Sustainable buildings and related construction techniques are becoming increasingly
recognized within the urban planning development in Qatar. The study aims to develop
an analytical review of sustainable green projects ...
Use of 3D Images to Evaluate Formation Damage Induced by Montmorillonite Fines in Porous Media Systems
(
Qatar Univesrity Press
, 2020 , Conference Paper)
Formation damage costs oil and gas industry $140 billion/year in lost productivity, this
is a key challenge to Qatar, the world's largest LNG exporter. During production from
a well, multiphase flow foster drag forces to ...
Investigation of the Effect of the Force-Frequency on the Behaviour of a New Viscous Damper for Railway Applications
(
Qatar Univesrity Press
, 2020 , Conference Paper)
The primary purpose of this work is to experimentally investigate the damping
coefficient of a viscous damper, intended to be used in railway applications to reduce
noise emission. The viscous shock absorber used in this ...
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. ...
Verification of ACI- 549 Code for Flexural Strengthening of Reinforced Concrete Beams Using FRCM
(
Qatar Univesrity Press
, 2020 , Conference Paper)
This paper presents an analytical study to verify the ACI 549-4R-16 code for
experimentally tested Reinforced Concrete (RC) beams, which were strengthened to
enhance the flexural capacity using Fiber-Reinforced Cementitious ...
The Investigation of an Efficient and Effective Proactive Pipeline Integrity System
(
Qatar Univesrity Press
, 2020 , Conference Paper)
In this paper, we propose the investigation of an efficient and effective proactive pipeline
integrity system that uses multi-sensors for monitoring and inspection of the pipeline.
Although the focus is on the pipeline, ...
Enhancement of Naphthalene Biodegradation by Sulfate Application in Brackish Subsurface Systems
(
Qatar Univesrity Press
, 2020 , Conference Paper)
Anaerobic biodegradation is the most dominant mechanism in the petroleum hydrocarbon
contaminated subsurface systems. Due to depletion of terminal electron acceptors such
as sulfate, anaerobic degradation of organic ...
Two different carrier phase shifted space vector PWM techniques for pole phase modulation based 9-phase induction motor drive
(
Institution of Engineering and Technology
, 2020 , Conference Paper)
The pole phase-modulated induction motor (PPMIM) drives fulfils all significant requirements of high power traction applications, like extended speed-torque capabilities, higher fault tolerance and high efficiency. In the ...
Accounting for the influence of the free surface on the vibration response of underground railway tunnels: A new iterative method
(
KU Leuven - Departement Werktuigkunde
, 2020 , Conference Paper)
This paper presents a new method for calculating the ground-borne vibration from shallow underground railways. The method is based on an iterative wave-scattering approach, which decouples the problem into two sub-systems: ...
