There are many applications for a compact device that is capable of indicating the direction of propagation of substrate vibration. In order to develop effective devices for this purpose, it can be helpful to examine biological systems that have evolved specialized sensory systems for finding a vibration source. We are studying an insect model of vibration localization that provides an approach...

There is strong evidence to suggest that acute indirect vibration acts on muscle to enhance force, power, flexibility, balance and proprioception suggesting neural enhancement. Nevertheless, the neural mechanism(s) of vibration and its potentiating effect have received little attention. One proposal suggests that spinal reflexes enhance muscle contraction through a reflex activity known as toni...

We develop and analyze a minimal hydrodynamic model to understand why a drop climbs a smooth homogeneous incline that is harmonically vibrated at an angle different from the substrate normal [P. Brunet, J. Eggers, and R. D. Deegan, Phys. Rev. Lett. 99, 144501 (2007)]. We find that the vibration component orthogonal to the substrate induces a nonlinear (anharmonic) response in the drop shape. Th...

One-on-one pursuit evasion game is the ideal research project for optimal search of agent. Without primal information about circumstance and evasion, it is helpful of enlighten search model for suiting to evade game. Virtual Force Model is one of most common enlighten random model. But it will make a center vibration in balance circumstance. This paper presents a rapid response virtual force mo...

Abstract In this paper, free vibration and transmission response for the torsional of circular annular plate are presented. To author’s knowledge, few studies can be found from wave standpoint. For purpose, in study, natural frequencies with clamped–clamped free–free boundaries calculated. The obtained by approach compared those derived classical method. Furthermore, transmissibility curves per...

One of the most common tasks in vibration analysis is the determination of the steady-state response of a system to harmonic forcing. This is also true in AC electrical circuit analysis. The most common case encountered in vibration engineering is that of the forced underdamped system. In this case, the transient portion of the response vanishes exponentially as e−ζωt, where ζ is the so-called ...

This paper proposes the refined first order shear deformation theory to investigate the free vibration behavior of bidirectional functionally graded porous plates. This theory satisfies the transverse shear stress free conditions at the top and bottom of the plate, thus avoids the need of a shear correction factor. The rule of mixtures is employed to compute the effective material properties an...

BACKGROUND Non-pharmacological options for symptomatic management of cough are desired. Although chest wall mechanical vibration is known to ameliorate cough reflex sensitivity, the effect of mechanical vibrations on perceptions of urge-to-cough has not been studied. Therefore, we investigated the effect of mechanical vibration of cervical trachea, chest wall and femoral muscle on cough reflex ...

To evaluate neurological symptoms in the vibration syndrome, 55 patients with vascular and neurological symptoms in the hand who had been exposed to vibration were examined. Their exposure to vibration was estimated and neurological vascular symptoms were evaluated according to symptom scales. Temperature thresholds were measured on the right thenar eminence and on the distal volar aspect of th...

The Shinkansen super-express railway system in Japan has greatly increased its capacity and has expanded nationwide. However, many inhabitants in areas along the railways have been disturbed by noise and ground vibration from the trains. Additionally, the Shinkansen railway emits a higher level of ground vibration than conventional railways at the same noise level. These findings imply that bui...
