Bi-attention DoubleUNet: A deep learning approach for carotid artery segmentation in transverse view images for non-invasive stenosis diagnosis
(
Elsevier
, 2024 , Article)
The carotid artery is a vital blood vessel that supplies oxygenated blood to the brain. Blockages in this artery can lead to life-threatening illnesses, making accurate diagnosis essential. While ultrasound (US) imaging ...
A frontier-based managerial approach for relative sustainability performance assessment of the world's airports
(
John Wiley and Sons Ltd
, 2021 , Article)
The sustainability impact of air transportation has become crucial to communities. Airports around the world are forced to be transparent with the society and to declare their sustainability results. As the sustainability ...
A novel hybrid cybersecurity scheme against false data injection attacks in automated power systems
(
Springer
, 2023 , Article)
The conventional power systems are evolving as smart grids. In recent times cyberattacks on smart grids have been increasing. Among different attacks, False Data Injection (FDI) is considered as an emerging threat that has ...
Biolubricant Synthesis by Additization and Chemical Modification from Lipid-Rich Brackish Coelastrella sp. Using a Biorefinery Approach
(
American Chemical Society
, 2023 , Article)
With a sizable market share and widespread use in automotive and industrial applications, biolubricants are produced from the oils of terrestrial plants that have undergone chemical modification or additive addition. ...
Mechanical and Fatigue Behavior of Cellular Structure Ti-6Al-4V Alloy Femoral Stems: A Finite Element Analysis
(
MDPI
, 2022 , Article)
Repetitive loads acting on the hip joint fluctuate according to the type of activities produced by the human body. Repetitive loading is one of the factors that leads to fatigue failure of the implanted stems. The objective ...
Synthesis of water capture technologies for gas fired power plants in Qatar
(
Institution of Chemical Engineers
, 2020 , Article)
Flue gas from gas fired power plants contains 10-16% (w/w) water vapor with considerable amount of latent heat. Although CO2 capture and utilization have received great attention, water capture from power plant has received ...
Optimization of Viscoelastic Metamaterials for Vibration Attenuation Properties
(
World Scientific
, 2020 , Article)
Metamaterials (MMs) are composites that are artificially engineered to have unconventional mechanical properties that stem from their microstructural geometry rather than from their chemical composition. Several studies ...
Investigating the effect of using softer rail-pads on ground-borne vibration from underground railways
(
Taylor and Francis Ltd.
, 2023 , Article)
In this study, a series of vibration measurements were performed on a section of one of the lines of the Doha Metro to explore the effect of changing rail-pads from conventional higher stiffness under-rail pads to lower ...
Fault classification using convolutional neural networks and color channels for time-frequency analysis of acoustic emissions
(
SAGE Publications Inc.
, 2023 , Article)
We present a novel method for real-time fault classification using the time history of acoustic emissions (AEs) recorded from a lab-scale gas turbine operating under normal and faulty conditions across multiple turbine ...
Using probabilistic neural networks for modeling metal fatigue and random vibration in process pipework
(
John Wiley and Sons Inc
, 2022 , Article)
Many experiments are usually needed to quantify probabilistic fatigue behavior in metals. Previous attempts used separate artificial neural network (ANN) to calculate different probabilistic ranges which can be computationally ...
