the well-known electro-mechanical analogy that equates current, voltage, resistance, inductance and capacitance to force, velocity, damping, spring constant and mass has a shortcoming in that mass can only be used to simulate a capacitor which has one terminal connected to ground. a new model that was previously proposed by the authors that combines a mass with a pulley (mp) is shown to simulat...

An electro-hydraulic profiling mechanism has been gradually applied to provide suitable downforce for a no-till row unit and ensure the consistency of seed sowing depth. In order improve control effect depth system solve problems complex structure, scattered valve sets equipment suitability an existing unit, this paper takes 2BJ-470B as carrier innovatively designs integrated pressure-reducing ...

We demonstrate a novel electro-optic swept source for wavenumber-linear interferometric sensing and imaging applications. The electro-optic swept source based on an acousto-optic tunable filter (AOTF) provides high environmental stability and arbitrary drive function sweeping because the electro-optic wavelength selection does not depend on a mechanical moving component to tune the output lasin...

The inertia and resistance of a wheelchair dynamometer must be determined in order to compare the results of one study to another, independent of the type of device used. The purpose of this study was to describe and implement a dynamic calibration test for characterizing the electro-mechanical properties of a dynamometer. The inertia, the viscous friction, the kinetic friction, the motor back-...

PURPOSE This study aimed to determine whether upgrade cardiac resynchronization therapy (CRT) shows better outcomes than de novo CRT. To do so, we compared the efficacy of CRT between de novo and upgrade groups, focusing particularly on the effect of upgrade CRT on patients with pacing-induced cardiomyopathy (PiCM). MATERIALS AND METHODS PiCM was defined as new-onset dilated cardiomyopathy fo...

We introduce and study some scalable domain decomposition preconditioners for cardiac electro-mechanical 3D simulations on parallel HPC (High Performance Computing) architectures. The electro-mechanical model of the cardiac tissue is composed of four coupled sub-models: (1) the static finite elasticity equations for the transversely isotropic deformation of the cardiac tissue; (2) the active te...

Power System Markets represented by dynamic equations provide insights into the market behaviour which are not available from static models. A combination of aggressive energy imbalance regulation and fast response of the market can lead to unstable market conditions. The dynamic properties of the market (as characterized by the eigenvalues of the market dynamic equations) are first determined ...

Abstract Electro‐active polymers (EAP) are smart materials that can deform dramatically and quasi‐instantaneously in response to an applied electric field. These properties make them suitable be used as soft robotic actuators. As any passive rubber‐like material, those electro‐sensitive components quasi‐incompressible may show pronounced time‐dependent hysteresis behaviour. The direction of the...
