AraFacts: The First Large Arabic Dataset of Naturally-Occurring Professionally-Verified Claims
(
Association for Computational Linguistics (ACL)
, 2021 , Conference Paper)
We introduce AraFacts, the first large Arabic dataset of naturally-occurring claims collected from 5 Arabic fact-checking websites, e.g., Fatabyyano and Misbar, covering claims since 2016. Our dataset consists of 6,222 ...
Sustainable Poultry house ventilation using Dew point indirect evaporative cooler aided with radiative cooling
(
American Society of Mechanical Engineers (ASME)
, 2021 , Conference Paper)
Maintaining good production quality in layer poultry houses is directly correlated to the thermal environment of the laying hens as well as their breathable air quality. This work compares the performance of two passive ...
A Single Inductor, Single Switch High Gain DC-DC Boost Converter
(
IEEE
, 2020 , Conference Paper)
Switched capacitor-based voltage multiplier cell (VMC) is generally employed to increase the output voltage of the dc-dc converter. The proposed converter is a new high gain dc-dc boost converter which utilizes only a ...
Air expulsion analysis of an industrial air valve using CFD
(
Institute of Electrical and Electronics Engineers Inc.
, 2021 , Conference Paper)
CFD (Computational Fluid Dynamic) analysis is a modern technique to estimate and determine fluid characteristics. CFD uses the Navier-Stokes equation to solve complex fluid behavior along with turbulence models such as k- ...
Areadynamic analysis of GMC sierra pickup truck
(
Institute of Electrical and Electronics Engineers Inc.
, 2021 , Conference Paper)
Computational Fluid Dynamics (CFD) was used to simulate the flow field over a GMC sierra pickup truck double cab (manufactured year of 2005). This simulation model was compared to a previous simulation and experimental ...
Modelling wave behaviour of elastic helical waveguides
(
Springer Nature
, 2020 , Conference Paper)
Curved and straight waveguides are ubiquitous in engineering structures. For modelling these structures in the mid-frequency and high-frequency range, the knowledge of the wave behaviour can be greatly beneficial. This ...
Characteristics, benefits, challenges, and socio-cultural factors of implementing pbl in qatar
(
Aalborg University
, 2020 , Conference Paper)
While project-and/or problem-based learning has been implemented in higher education worldwide for several decades, both modes of PBL remain a new phenomenon in Qatar. Over the past few years, several research projects ...
Effect of Alkaline Activators on the Mechanical Properties of Geopolymer Mortar
(
Qatar Univesrity Press
, 2020 , Conference Paper)
"Geopolymerization is a process where silica and alumina rich source materials turn
into excellent binding materials by the aid of alkali solutions. Materials such as fly ash
are by-products in energy power plants. Fly ...
Evaluating the Operational Impact of Left-Turn Exclusive Number of Lanes: A Case Study from Qatar
(
Qatar Univesrity Press
, 2020 , Conference Paper)
Left-turning movements can significantly reduce the overall capacity of signalized
intersections due to the queueing built up. Intersections with heavy left-turning volumes
tend to use multiple lanes to accommodate left-turn ...
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 ...
