Characterizing fracture toughness using machine learning
( Elsevier B.V. , 2021 , Article)The existing models for fracture toughness characterization based on nanoindentations that account for the fracture length are limited to simple (ideal) geometries that are absent in shales. The present study proposes two ... -
Chemical Characterization and Source Identification of Beached Oil from Two Areas Along the North-Western Coast of Qatar
( Hamad bin Khalifa University Press (HBKU Press) , 2016 , Conference Paper)Over the years there have been several reports of oil spills affecting particularly the northern coast of Qatar. In most cases, the source of oil spills is not identified. The spilled oils are very resistant to degradation ... -
Chlorophyll-a concentrations in the Arabian Gulf waters of arid region: A case study from the northern coast of Qatar
( Elsevier , 2022 , Article)Remote sensing of spectrally active Chlorophyll-a (Chl-a) in the gulf water of an arid region is important to understand the spatial and temporal variations of phytoplankton and biomass in the water. This study characterizes ... -
