Schematic diagram of the whale optimization algorithm (WOA)–optimized fuzzy proportional–integral–derivative (PID) controller. The WOA is employed to dynamically tune the scaling factor expressions and fuzzy control parameters (a(e)a(e), a(ec)a(ec), βpβp, βiβi), as well as the initial PID gains (kp0kp0, ki0ki0), based on the error (ee) and its ...

Combining differential quadrature method with simulation technique to
Nowadays, most of the ordinary differential equations (ODEs) can be solved by modelica-based approaches, such as Matlab/Simulink, Dymola and LabView, which use simulation technique (ST). However, these kinds of approaches restrict the users in the enforcement of conditions at any instant of the time domain.

ABSTRACT Hybrid modeling combines first‐principles equations with a data‐driven subcomponent. Training for the data‐driven part is sensitive to measurement noise when training targets are constructed using pointwise time derivatives. Beyond differentiation errors, hybrid models involve solving an inverse problem to estimate the data‐driven term, which ...

Increasing Respiration Weakens the Carbon Sink Over Two Decades in a Temperate Deciduous Forest
Using a 20‐year eddy covariance record from a temperate deciduous forest, we show that net carbon uptake declined over two decades. Both the trend and interannual variability in net carbon exchange were respiration driven, with warming winters and increasing late‐summer diffuse light driving the trend in respiration.

Longitudinal 1H and 129Xe Lung MRI in Patients With Post‐COVID Residual Lung Abnormalities
ABSTRACT Background It is unclear how lung function may recover in patients with residual lung abnormalities (RLAs) following COVID‐19 pneumonia. Purpose To evaluate lung function trends over time in patients with RLAs following hospitalization due to COVID‐19. Study Type Prospective, multicenter longitudinal cohort study.
