Background: In Neonatal intensive care units (NICU) different sound intensities and frequencies are produced from different sources, which may exert undesirable physiological effects on the infants. The aim of this study was to determine the noise level and its sources in the NICU and neonatal ward of Al-Zahra Hospital of Rasht, Iran. Methods: In this descriptive cross-sectional study, the inte...

This thesis describes the potential use of re-entrant microwave resonant three-dimensional cavities as low-loss electrical component in strongly coupled electromechanical systems. In particular , I have investigated radiative processes as a loss mechanism of a re-entrant cavity in a geometry similar to those used in electromechanical experiments undertaken by the Lehnert lab. First, I present t...

OBJECTIVES Although electromechanical-assisted gait training after stroke seems to be effective, in the absence of a direct comparison between electromechanical devices it is not clear which device may be the most effective for recovery of walking. The aim of this study was therefore to compare the effects of different devices used in gait training after stroke. DATA SOURCES We searched the C...

This paper presents the design of an experimental electromechanical device for vibration control and energy harvesting. Traditionally, when the broadband resonant response due to a selected mode of a lightly damped structure needs to be controlled a vibration absorber is used. The resonance frequency of the absorber can be chosen to minimise the response of the structure under control. Optimisi...

TEM Cantilever Chips In article number 2301439, Chaojian Hou, Jing Zhao, Lixin Dong, and co-workers report a cantilever chip for in situ transmission electron microscopy (TEM). The consists of MoS2 opto-electromechanical sensor plasmonic antenna array built on the top Si3N4 cantilever, forming an electron-beam-transparent (thickness ≈100 nm) nano-opto-electromechanical system (NOEMS), enabling ...

In an electromechanical which-path device electrons travelling through an Aharonov– Bohm ring with a quantum dot in one of the arms are dephased by an interaction with the fundamental flexural mode of a radio-frequency cantilever, leading to a reduction in the visibility of interference fringes. However, at finite temperatures time-averaged measurement of the current leads to a fringe visibilit...

This paper describes the design of the overall structure about evaluation system of the development process of complex electromechanical device, and analyzes quality evaluation of the stage of scheme design in detail. An evaluation index system of quality of development process is proposed based on resources and conditions, technical status control, management control. Take the evaluation of sc...

This thesis describes electrostatic actuation techniques and mechanical design features for realizing large planar analog vertical travel in an electrostatically actuated diffractive mid-infrared optical device, which is robust, both to manufacture, and against pull-in during use. This device, called the Polychromator, is fabricated by polysilicon surface-micromachining and consists of many par...
