Lumped-parameter model of renal hemodynamics

open access: yes, 2005
The blood flow through a porous and distensible vessel such as a glomerular capillary is studied using a lumped-parameter model, and based on simplified Navier-Stokes’ equations to derive the governing equations in the form of second-order hyperbolic partial differential equations in pressure.

Seizure forecasting with epilepsy cycles: On the causality of forecasting pipelines

open access: yesEpilepsia, EarlyView.
Abstract Objective Seizure risk is modulated by multiscale brain rhythms. Previous studies using cycles in electroencephalography, heart rate, and wearable data suggest the possibility of forecasting seizures days in advance. However, they commonly rely on methods requiring (days of) information from time points beyond the moment of forecast (noncausal

Scour‐Conditioned Seismic Fragility Analysis of Monopile‐Supported Offshore Wind Turbines

open access: yesEarthquake Engineering &Structural Dynamics, EarlyView.
ABSTRACT Monopile‐supported offshore wind turbines (MS‐OWTs) are increasingly deployed in seismic coastal regions, where they face compound risks from earthquake loading and seabed scour. While past studies have addressed these hazards separately, seismic fragility under evolving scour conditions remains insufficiently understood. This study introduces

Time‐ and State‐Dependent Damage Accumulation Due to Aftershocks Under an M9.0 Megathrust Earthquake in the Cascadia Subduction Zone

open access: yesEarthquake Engineering &Structural Dynamics, EarlyView.
ABSTRACT This study develops a comprehensive framework for assessing time and state‐dependent aftershock damage accumulation under an M9.0 megathrust interface earthquake in the Cascadia Subduction Zone (CSZ). The framework integrates aftershock probabilistic seismic hazard analysis (APSHA) and state‐dependent fragility analysis (SDFA) within a ...

Position Control of Electro‐Hydraulic Actuator System With Disturbances Compensation

open access: yesEnergy Science &Engineering, EarlyView.
A novel output feedback controller based on global fast terminal sliding mode with disturbances rejection to achieve accurate position tracking control for electro‐hydraulic cylinder system, which shows the great control potential of the designed output feedback controller during the start‐up and operation of the electro‐hydraulic actuator system ...
