Investigation of the wake energy recovery of cross-flow turbines in paired configuration by means of 3d-CFD and analysis of the streamwise momentum budget [PDF]

E3S Web of Conferences, 2021
Literature suggests that cross-flow turbines (CFTs) could be suitable for off-shore wind farms because of the high power-density achievable by shortening the distance between arrays as allowed by a fast wake energy recovery experimentally detectable.

Activated mast cells in skeletal muscle can be a potential mediator for cancer‐associated cachexia

Journal of Cachexia, Sarcopenia and Muscle, 2021
Background Eighty per cent of United States advanced cancer patients faces a worsened prognosis due to cancer‐associated cachexia. Inflammation is one driver of muscle atrophy in cachexia, and skeletal muscle‐resident immune cells could be a source of ...

Experimental study of the wake interaction between two vertical axis wind turbines

Wind Energy, 2023
Wakes and wake interactions in wind turbine arrays diminish energy output and raise the risk of structural fatigue; hence, comprehending the features of rotor–wake interactions is of practical relevance.

New Key Recovery in WAKE Protocol [PDF]

, 2001
Wireless authentication and key establishment (WAKE) protocols are essential in mobile communications. The key recovery mechanism may also be required in mobile communication systems for the investigation of serious crimes and for national security. Recently some protocols that give key recovery in the WAKE protocol have been published.

Impact of Turbulent Time Scales on Wake Recovery and Operation [PDF]

Journal of Physics: Conference Series, 2022
Abstract Enhancing wake recovery behind wind turbines has the potential to significantly improve the power production and efficiency of large wind farms. Rather than investigating turbine control strategies, floater motion or global turbulent quantities such as turbulence intensity, this work aims to study wake stability and recovery ...

Supply chain recovery challenges in the wake of COVID-19 pandemic

Journal of Business Research, 2021
The COVID-19 pandemic has revealed the fragility of global supply chains arising from raw material scarcity, production and transportation disruption, and social distancing. Firms need to carefully anticipate the difficulties during recovery and formulate appropriate strategies to ensure the survival of their businesses and supply chains.
