This paper presents a new approach of health monitor using the curvature of the influence line. The study included numerical simulation and experimental test of Hbeam to demonstrate the effectiveness of the new approach. The specific work includes: loading test method for moving vehicular to measure displacement influence line of beam structure, obtaining Eigen-damage intrinsic mode function (I...

Elastography or elasticity imaging techniques typically image local strains or Young's modulus variations along the insonification direction. Recently, techniques that utilize angular displacement estimates obtained from multiple angular insonification of tissue have been reported. Angular displacement estimates obtained along different angular insonification directions have been utilized for s...

The displacement of the mitotic spindle to one side of a cell is important for many cells to divide unequally. While recent progress has begun to unveil some of the molecular mechanisms of mitotic spindle displacement, far less is known about how spindle displacement is precisely timed. A conserved mitotic progression mechanism is known to time events in dividing cells, although this has never ...

We discuss the problem of trapping and mobilization of nonwetting fluids during immiscible two-phase displacement processes in porous media. Capillary desaturation curves give residual saturations as a function of capillary number. Interpreting capillary numbers as the ratio of viscous to capillary forces the breakpoint in experimental curves contradicts the theoretically predicted force balanc...

BACKGROUND AND OBJECTIVES Atrioventricular plane displacement is a well-accepted method for assessment of left ventricular systolic function. We explored the ability of atrioventricular plane displacement to predict inhospital outcome in patients with acute ST-elevation myocardial infarction. MATERIALS AND METHODS Ninety three patients with acute ST-elevation myocardial infarction were prospe...

The Varian Real-time Position Management (RPM) system allows respiratory gating based on either the phase or displacement (amplitude) of the breathing waveform. A problem in clinical application is that phase-based gating, required for respiration-correlated (4D-CT) simulation, is not robust to irregular breathing patterns during treatment, and a widely used system version (1.6) does not provid...

To build the equivalent relationship of mechanical behavior ring nets under static punching and dynamic impact conditions, a series tests with different parameters were conducted. The coefficients breaking force, displacement, net energy dissipation defined to describe potential relationship. Besides, sensitivity analyses made. results showed that, increase velocity, force decreased as power fu...

HYPOTHESIS The aim of this study was to investigate the impact of cochlear implant electrode insertion on middle-ear low frequency function in humans. BACKGROUND Preservation of residual low frequency hearing with addition of electrical speech processing can improve the speech perception abilities and hearing in noise of cochlear implant users. Preservation of low frequency hearing requires a...

according to development of displacement–performance based design, there are some studies on different structures which most of them are about regular plan structures. in this research has been tried to review the frame steel structures designed based on 2800 standard of iran to achieve the designed structures performance level to find how much function levels it covers in earth quake. to show ...

This study considers an analytical method to detect the damage location from the moment diagram calculated by the external forces and the forces required for obtaining the same deflections as the measurement deflections. The measured deflections must be a part of displacements to restrict the static behavior of the damaged beam. The constraint forces acting at measurement points are derived by ...
