Dynamic Characterization of Cercal Mechanosensory Hairs of Crickets

open access: yesInsects, 2012
Previous dynamic characterizations of the cercal mechanosensory hairs of crickets have generally been limited to the first resonant frequency and associated deflection shape.

SCALING OF OPERATIONAL MODE SHAPES USING SENSITIVITY ANALYSIS [PDF]

open access: yesمجله مدل سازی در مهندسی, 2009
Recently, identification of dynamic properties of structures such as bridges, towers and building, which are not easy to excite, is possible by measuring only the output responses. Due to measuring only the responses when the structure is excited only by

Influence of Mechanical Properties on Modal Analysis of Natural Fiber Reinforced Laminated Composite Trapezoidal Plates

open access: yesJournal of Natural Fibers, 2021
Present work concentrates on modal parameters of laminated composite plates composed of natural fibers reinforced with unsaturated polyester resin. The selected jute and ramie fibers underwent alkaline treatment to improve mechanical properties.

Thermometry based on Whispering Gallery Mode resonators [PDF]

open access: yes, 2012
Whispering gallery (WG) mode resonators were studied since 1980s for precision clock oscillators and for cavity quantum electrodynamics studies. They are a kind of stable, high Q, microwave resonators where a symmetric dielectric medium, such as a ...

Determination of mode shapes of a multiple cracked beam element and its application for free vibration analysis of a multi-span continuous beam

open access: yesVietnam Journal of Mechanics, 2013
This article presents some results on the determination of the vibration shape function of a multiple cracked elastic beam element, which is modeled as an assembly of intact sub-segments connected by massless rotational springs.

Design of a Novel Type Micro-Stirrer Excited by Longitudinal Elastic Wave for Thrombus Dissolution

open access: yesJournal of Biomechanical Science and Engineering, 2011
This paper presents the method to design a novel micro stirrer for high effective dissolution of cerebral thrombus or blood clot. The micro stirrer is a beam with supported one side and the other side is attached to an asymmetrical stirrer.

T-shaped mode coupler for two-mode mode division multiplexing

open access: yesIEICE Electronics Express, 2011
We propose a novel type of mode coupler consisting of two identical rectangular few-mode waveguides with different orientations. Numerical simulation indicates that mode extinction ratio exceeding 20dB can be achieved by well-aligned waveguides.

Deformation and Fracture of Thin Sheets of Nitinol [PDF]

open access: yes, 2007
Nickel-Titanium (Nitinol) is a Shape Memory Alloy (SMA) that exhibits superelasticity (pseudoelasticity) and shape memory by a solid-solid state diffusion-less phase transformation.
