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

Canadian journal of civil engineering (Print), 2020 In this paper, a novel pier scour indicator is introduced, which uses the ratio between mode shape amplitudes identified at two points on an integral bridge structure to monitor the progression of scour erosion. The mode shape ratio (MSR) is investigated

Damage identification in a concrete beam using curvature difference ratio [PDF]
, 2011 Previous studies utilising changes in mode shape or curvature to locate damage rely on the fact that the greatest change occurs around the defect. However, in concrete beams this fact is undermined due to the nature of the defect as distributed multi ...

Unstable spiral modes in disk-shaped galaxies [PDF]
Proceedings of the National Academy of Sciences, 1976 The mechanisms for the maintenance and the excitation of trailing spiral modes of density waves in diskshaped galaxies, as proposed by Lin in 1969 and by Mark recently, are substantiated by an analysis of the gas-dynamical model of the galaxy. The self-excitation of the unstable mode in caused by waves propagating outwards from the corotation circle ...

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

Shaping Effects on Non-Ideal Ballooning Mode [PDF]
Plasma and Fusion Research, 2018 The dependence of shaping effects on the growth rate of collisionless and resistive ballooning mode (CBM/RBM) is numerically investigated. That of the drift ballooning modes (DCBM/DRBM) is also investigated by taking kinetic effects into account. Resistivity scans of linear growth rates of CBM/RBM and DCBM/DRBM in a circular geometry show that both ...

An Advanced Edge-Detection Method for Noncontact Structural Displacement Monitoring
Sensors, 2020 A non-contact vision sensor system for monitoring structural displacements with advanced Zernike subpixel edge detection technique is suggested in this paper. Edge detection can detect features of objects effectively without using templates.

Experimental Study on the Natural Dynamic Characteristics of Steel-Framed Modular Structures
Buildings, 2022 Corner-supported modular structures are made of repetitive prefurnished, prefinished modular units, which are fabricated in a factory and transported to the site of a building to form a permanent building block.

Mode Shape-Based Damage Localization in Steel Plates Using a Detection Index Based on 2D Wavelet Analysis [PDF]
Journal of Rehabilitation in Civil Engineering, 2023 Structures are subjected to a variety of environmental and loading conditions over time, and minor damage to structural elements may occur. By timely identifying damage and repairing damaged locations, it is possible to prevent the spread and development

Universal shape law of stochastic supercritical bifurcations: Theory and experiments [PDF]
, 2007 A universal law for the supercritical bifurcation shape of transverse one-dimensional (1D) systems in presence of additive noise is given. The stochastic Langevin equation of such systems is solved by using a Fokker-Planck equation leading to the ...
