This paper presents a piezoelectric vibration energy harvester (PVEH) with resonance frequencies shifted down by elastically supported masses.The added elastic supporters can diminish the equivalent stiffness BAG of the whole structure, leading to an evident decline in the resonance frequency of the cantilever body.Meantime, a new resonant peak is
This paper adopts the tail-event driven network (TENET) framework to explore the connectedness and systemic risk of the banking industry along the Belt and Road (B&R) based on weekly returns of 377 publicly-listed banks from 2014 to 2019.We conduct the connectedness analysis from four levels (i.e., system, region, country and institution) and ident
Multiframe PC box-girder bridge with intermediate hinges is a kind of bridge having complex Course a pied - Homme - Vetements - Chandail - Long sleeves structural characters, which is very quintessential in California.In this study, a typical bridge was adopted to establish a nonlinear dynamic model through OpenSees platform.Intermediate hinge and
Lubricant condition monitoring (LCM) is a preferred condition monitoring (CM) technology for fault diagnosis and prognosis owing to its ability to derive a wide range of information from the system (machine/equipment) state and lubricant state.Given the importance of LCM for maintenance decision support, an accurate and reliable remaining useful li
