Forcecardiography: A Novel Technique to Measure Heart Mechanical Vibrations onto the Chest Wall. [PDF]
Sensors (Basel), 2020 This paper presents forcecardiography (FCG), a novel technique to measure local, cardiac-induced vibrations onto the chest wall. Since the 19th century, several techniques have been proposed to detect the mechanical vibrations caused by cardiovascular ...

Modelling and simulations of reactor neutron noise induced by mechanical vibrations
Annals of Nuclear Energy, 2022 Mechanical vibrations of core internals are among the main perturbations that induce oscillations in the neutron flux field, also known as neutron noise. In this work, different simulation models for the study of the influence of the mechanical vibrations ...

Grey-box state-space identification of nonlinear mechanical vibrations [PDF]
International Journal of Control, 2018 The present paper deals with the identification of nonlinear mechanical vibrations. A grey-box, or semi-physical, nonlinear state-space representation is introduced, expressing the nonlinear basis functions using a limited number of measured output ...

Spectral Analysis of ATP-Dependent Mechanical Vibrations in T Cells [PDF]
Frontiers in Cell and Developmental Biology, 2021 Mechanical vibrations affect multiple cell properties, including its diffusivity, entropy, internal content organization, and thus—function. Here, we used Differential Interference Contrast (DIC), confocal, and Total Internal Reflection Fluorescence ...
