This study investigates the effects of magnetic constraints on a piezoelectric energy harvesting absorber while simultaneously controlling primary structure and harnessing energy. An accurate forcing representation force is investigated developed. A reduced-order model derived using Euler–Lagrange principle, impact evaluated absorber’s static position coupled natural frequency system. The resul...

Abstract The size dependent static pull-in instability of functionally graded (FG) microbeams in micro-electromechanical systems (MEMS) is studied, considering the influence axial force. material properties are varied beam thickness by a power-law function, and they calculated rule mixture. To account for microsize effect, classical Euler-Bernoulli theory employed combination with modified coup...

Many corporate events are self-selected, but the relative impact of internal (firm-specific) and external (environmental) influences on discretionary corporate decisions remains largely unknown. In this paper, focusing on corporate debt issuance, we apply the contemporary push-pull theory to establish whether bond issuance are pushed by the firms due to internal considerations, or pulled by the...

The operational range of MEMS electrostatic parallel plate actuators can be extended beyond pull-in with the presence of an intermediate dielectric layer, which has a significant effect on the behavior of such actuators. Here we study the behavior of cantilever beam electrostatic actuators beyond pull-in, using a beam model. Three possible static configurations of the beam are identified over t...

Strengthening muscles of the back may have various implications for improving functions of daily living, aiding in the transfer of power in throwing, and assist in injury prevention of the shoulder complex. While several versions of the pull-up exist, there is currently no literature comparing their differences. The purpose of this investigation was to compare the electromyographical activity o...

With the deepening of global financial crisis and debt crisis, currency wars are escalating and trade protection is getting worse. Crisis of confidence in the national level is gradually spread to the enterprise level, virtual enterprise based on the global manufacturing particularly faces serious crisis of confidence. To analyzing and evaluating Virtual Enterprise venture, trust network struct...

The Klebsiella oxytoca pullulanase secreton (type II secretion system) components PulM and PulL were tagged at their N termini with green fluorescent protein (GFP), and their subcellular location was examined by fluorescence microscopy and fractionation. When produced at moderate levels without other secreton components in Escherichia coli, both chimeras were envelope associated, as are the nat...

PURPOSE The effects of aging on tissue strength and its ability to withstand forces associated with MRI have not been investigated. This study aimed to determine the forces required to cause partial or total detachment of a heart valve prosthesis in patients with age-related degenerative diseases exposed to MRI. METHODS Eighteen tissue samples excised during routine heart valve replacement su...
