Transforming Challenges into Opportunities for Qatar’s Food Industry: Self-Sufficiency, Sustainability, and Global Food Trade Diversification
( MDPI , 2023 , Article)Food trade restrictions pose a serious risk for countries that are heavily reliant on food imports, potentially leading to food crises, inequality, and geopolitical conflicts on a global scale. However, such restrictions ... -
Transient 3D simulations of turbulent premixed flames of gas-to-liquid (GTL) fuel in a fan-stirred combustion vessel
( Elsevier , 2021 , Article)This work aims to conduct turbulent flame studies of GTL fuel and 50/50 diesel-GTLblend and compare them to diesel under a wide range of equivalence ratio (0.7 < Ф < 1.3) and turbulence intensities (0.5 m/s < u′ < 3.0 m/s). ... -
Transient gas turbine performance diagnostics through nonlinear adaptation of compressor and turbine maps
( American Society of Mechanical Engineers (ASME) , 2015 , Article)Gas turbines are faced with new challenges of increasing flexibility in their operation while reducing their life cycle costs, leading to new research priorities and challenges. One of these challenges involves the ... -
Transient response of porous FG nanoplates subjected to various pulse loads based on nonlocal stress-strain gradient theory
( Elsevier Ltd , 2019 , Article)Based on nonlocal strain gradient theory (NSGT), transient behavior of a porous functionally graded (FG) nanoplate due to various impulse loads has been studied. The porous nanoplate has evenly and unevenly distributed ... -
Transient response of porous inhomogeneous nanobeams due to various impulsive loads based on nonlocal strain gradient elasticity
( Springer Netherlands , 2019 , Article)Transient vibration responses of a porosity-dependent functionally graded nanobeam under different impulsive loadings have been investigated in the context of non-local strain gradient theory. Three impulse loads of ... -
Transit-oriented Development from the View of Traditional City Model
( Qatar University Press , 2023 , Conference Paper)Several communities have adopted the transit-oriented development (TOD) model to improve the urban form of the city. Through the TOD model, citizens are enabled and encouraged to travel by public transit and live near it, ... -
