We present a fully coupled electromechanical model of the heart. The model integrates cardiac electrophysiology and cardiac mechanics through excitation-induced contraction and deformation-induced current. Numerical schemes based on finite element were implemented in a supercomputer. Numerical

, and can be used to calculate the phase velocity dispersion and the electromechanical coupling coefficients of a layered piezoelectric medium exactly. In this paper, the formulation based on the matrix method for calculating the effective permittivity of a layered piezoelectric medium with three types

The results of the model presented here describe the effects of the viscoelastic damping element of the electromechanical

The rigid-flexible coupling system with a hub and concentrated mass is studied in this paper. Considering the second-order coupling of axial displacement which is caused by transverse deformation of the beam, the dynamic equations of the system are established using the second Lagrange equation

of the stepping motor. The main purpose of these studies is to indicate essential differences between the torsional dynamic responses obtained for the considered object regarded respectively as electro-mechanically coupled and uncoupled. From the computational results, it follows that these differences

The electrical properties of tubular muscle fibers were completely characterized and analyzed by measuring two independent functions of frequency, i.e., the characteristic impedance and the propagation function. The impedance of a single tubular muscle fiber was determined with microelectrodes over the frequency

This paper presents electromechanical coupled dynamic model of micro- plate subjected to electrostatic excitation. Equations of motion of laterally deformed thin plate are obtained analytically. The static displacement and dynamic characteristics of microplate are depicted as closed-form solutions

We introduce a new class of predictors, cross-metric predictors, that use one metric to predict another, thus making possible an efficient
