The impact of the Caputo fractional derivative on unsteady mixed convention boundary layer flow Casson fluid is investigated. It evaluated via two different geometries which are plate and microchannel with oscillating motion. problems modelled using a set partial differential equations appropriate initial conditions. dimensional turned into dimensionless governing by relevant variables. obtaine...

We evaluated the hypothesis that postural instability precedes the onset of motion sickness. Subjects standing in a "moving room" were exposed to nearly global oscillating optical flow. In the experimental condition, the optical oscillations were a complex sum-of-sines between 0.1 and 0.3 Hz, with an excursion of 1.8 cm. This optical motion was of such low frequency and magnitude that it was so...

Beghi, Xausa, Tomat, and Zanforlin (J. Math. Psychol. 41(1997) 11) present a visual stereokinetic illusion. In the image plane, one end of an oblique bar moves horizontally back and forth, while the other end is stationary. Perceptually, this becomes a bar of a constant length rotating in depth around a vertical axis that passes through the stationary end of the bar. Beghi et al. (1997) provide...

A simple analytical model of the stationary flow through the mouthpiece of a single reed music instrument is developed. Preliminary measurements of the non—stationary volume flow through an oscillating valve (as used in organ pipes) and a clarinet reed are presented. In both cases the flux induced by the reed motion is observed.

If we could realize an autonomous polymer system driven under biological conditions by a tailor-made molecular design, human beings could create unprecedented biomimetic functions and materials such as heartbeats, autonomous peristaltic pumps, etc. In order to achieve this objective, we have investigated the molecular design of such a polymer system. As a result, we were the first to demonstrat...

We calculate transition amplitudes and probabilities between the coherent Fock states of a quantum harmonic oscillator with moving center for an arbitrary law motion. These quantities are determined by Fourier transform acceleration. In case constant acceleration, oscillate frequency, so that no excitation occurs after every period. Examples oscillating rotating motion trap considered too. Esti...

We used the Pulfrich effect to investigate perception of motion in depth. Independent manipulation of spatial and temporal frequency content in stereoscopic motion stimuli revealed the tuning characteristics of motion-in-depth perception. Sensitivity to interocular phase difference between sinusoidally oscillating sine-wave gratings was measured in four observers who judged direction of motion ...

In this paper, we propose the Chebyshev wavelet approximation for the numerical solution of a class of integrodifferential equation which describes the charged particle motion for certain configurations of oscillating magnetic fields. We show that the Chebyshev approximation transform an integral equation to an explicit system of linear algebraic equations. Illustrative examples are included to...
