An efficient piezoelectric sandwich beam finite element is presented here. It employs the coupled polynomial field interpolation scheme for field variables which incorporates electromechanical ...

Add a description, image, and links to the lagrange-polynomial-interpolation topic page so that developers can more easily learn about it.

Accurate frequency estimation in a wideband digital receiver using the FFT algorithm encounters challenges, such as spectral leakage resulting from the FFT’s assumption of signal periodicity.

Abstract: This work used a physical model based on a system of vertical communicating vessels adding a plunger with linear displacement, a physical analysis was made finding a mathematical expression ...

Abstract: A high order polynomial interpolation method is proposed for the motion planning of the fast opening of the protection cover, which is based on its characteristics to ensure the steady ...

ABSTRACT: Fractal geometry provides a new insight to the approximation and modelling of experimental data. We give the construction of complete cubic fractal splines ...
