Compact hybrid electrohydraulic actuators using smart materials: A review
TL;DR: The development of compact hybrid electrohydraulic actuators driven by various smart materials has been widely reported in the literature in recent years as mentioned in this paper, and the basic operation of these hybrid actuators involves high-frequency bidirectional operation of an active material that is converted to unidirectional motion of a hydraulic fluid by a set of valves.

Free vibration and buckling analysis of plates using B-spline wavelet on the interval Mindlin element
TL;DR: In this paper, a finite element method (FEM) of B-spline wavelet on the interval (BSWI) is used to solve the free vibration and buckling problems of plates based on Reissner-Mindlin theory.

Spectral element modelling and analysis of a pipeline conveying internal unsteady fluid
TL;DR: In this paper, a spectral element model is developed for the uniform straight pipelines conveying internal unsteady fluid, where four coupled pipe-dynamics equations are derived first by using the Hamilton's principle and the principles of fluid mechanics.
