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

Next, we'll create two different FastChebInterpolation s, one representing an interpolation of the periodic orbit, and another representing an approximation of the orbit employing a least-squares fit ...

This is a preview. Log in through your library . Abstract Techniques of univariate Newton interpolating polynomials are extended to multivariate data points by different generalizations and practical ...

Polynomial interpolation to analytic functions can be very accurate, depending on the distribution of the interpolation nodes. However, in equispaced nodes and the like, besides being badly ...

Abstract: The high-efficiency robotic edge grinding technology for precision forged blades of aero engines can significantly improve the blade machining quality, enhance the engine performance ...

Abstract: This contribution presents an idea of polynomial-based filters with segments of different lengths which can be effectively used for sampling rate conversion. For these filters the impulse ...

:::{prf:definition} Interpolation problem Given $n+1$ distinct points $(t_0,y_0)$, $(t_1,y_1),\ldots,(t_n,y_n)$, with $t_0<t_1<\ldots <t_n$ called nodes, the ...
