Transient Temperature Effects on the Aerothermoelastic Response of a Simple Wing

open access: yesAerospace, 2018
Aerothermoelasticity plays a vital role in the design and optimisation of hypersonic aircraft. Furthermore, the transient and nonlinear effects of the harsh thermal and aerodynamic environment a lifting surface is in cannot be ignored.

Improved Virtual Synchronous Generator-Based Control Scheme for Enhanced Transient Response in Microgrids

open access: yesEngineering Proceedings, 2023
Synchronous generator-based power stations, with their inherent inertia, can maintain frequency stability during sudden load switching, while distributed generating station-driven microgrids suffer from a lack of natural inertia. Cascaded power, voltage,

Non-Monotonic Effect of Substrate Inhibition in Conjunction with Diffusion Limitation on the Response of Amperometric Biosensors

open access: yesBiosensors
The non-monotonic behavior of amperometric enzyme-based biosensors under uncompetitive and noncompetitive (mixed) substrate inhibition is investigated computationally using a two-compartment model consisting of an enzyme layer and an outer diffusion ...

N2O Decomposition over Fe-ZSM-5: A Systematic Study in the Generation of Active Sites

open access: yesMolecules, 2020
We have carried out a systematic investigation of the critical activation parameters (i.e., final temperature (673–1273 K), atmosphere (He vs. O2/He), and final isothermal hold (1 min–15 h) on the generation of “α-sites”, responsible for the direct N2O ...
