The impact of meltwater discharge from the Greenland ice sheet on the Atlantic nutrient supply to the northwest European shelf [PDF]

open access: yesOcean Science, 2020
Projected future shoaling of the wintertime mixed layer in the northeast (NE) Atlantic has been shown to induce a regime shift in the main nutrient supply pathway from the Atlantic to the northwest European shelf (NWES) near the end of the 21st century ...

Enhancement of dynamic wireless power transfer system by model predictive control

open access: yesIET Power Electronics, 2022
Wireless power transfer (WPT) system based on a dynamic wireless charging (DWC) scheme, eliminates waiting time for charging electric vehicles (EVs), increases the range of motion, reduces the size of Li‐ion battery, and automates the charging process ...

Mathematical Modeling of a Transient Vibration Control Strategy Using a Switchable Mass Stiffness Compound System

open access: yesShock and Vibration, 2014
A theoretical control strategy for residual vibration control resulting from a shock pulse is studied. The semiactive control strategy is applied in a piecewise linear compound model and involves an on-off logic to connect and disconnect a secondary mass

A fundamental study of dynamic behavior of vehicles with unstable region under force control

open access: yesNihon Kikai Gakkai ronbunshu, 2015
The primary method of improving steering dynamic response performance is expected to involve position control. However the driver uses not only the position of the steering wheel but also torque for control.

Extreme springing response statistics of a tethered platform by deconvolution

open access: yesInternational Journal of Naval Architecture and Ocean Engineering, 2023
The research examines the motion response and hydrodynamic wave loads of a deep-water Tension Leg Platform (TLP), emphasising the impacts of the wave sum frequency on the restrained modes of heave, roll, and pitch.

Evaluation of the Autoparametric Pendulum Vibration Absorber for a Duffing System

open access: yesShock and Vibration, 2008
In this work we study the frequency and dynamic response of a damped Duffing system attached to a parametrically excited pendulum vibration absorber. The multiple scales method is applied to get the autoparametric resonance conditions and the results are

Vertical Vibration Suppression System for Railway Vehicles Based on Primary Suspension Damping Control — System Development and Vehicle Running Test Results —

open access: yesQuarterly Report of RTRI, 2011
Suppression of vertical bending vibration is essential to improve ride comfort on railway vehicles. For this purpose, a primary suspension damping force control system is being developed. This paper describes the composition of the system and reports on the results from vehicle running tests on some Shinkansen lines using actual Shinkansen vehicles ...

Tumour–host interactions in Drosophila: mechanisms in the tumour micro‐ and macroenvironment

open access: yesMolecular Oncology, EarlyView.
This review examines how tumour–host crosstalk takes place at multiple levels of biological organisation, from local cell competition and immune crosstalk to organism‐wide metabolic and physiological collapse. Here, we integrate findings from Drosophila melanogaster studies that reveal conserved mechanisms through which tumours hijack host systems to ...

Application of an Artificial Fish Swarm Algorithm in an Optimum Tuned Mass Damper Design for a Pedestrian Bridge

open access: yesApplied Sciences, 2018
Tuned mass damper (TMD) has a wide application in the human-induced vibration control of pedestrian bridges and its parameters have great influence on the control effects, hence it should be well designed.
