Roughness is probably the most salient dimension pertaining to the perception of textures by touch and has been widely investigated. There is a controversy on how roughness relates to the texture’s spatial period and which factors influence this relation. Here, roughness during bare finger exploration of coarse textures is studied for different types of textures with elements of low height (0.3...

This study deals with the elderly fare pricing issue for taking express buses in morning peak period. As many passengers are not commuters, discount policy may be an opportune option when get overcrowded. Imposing surcharge on becomes a potentially beneficial measure that encourages appropriate number of to circumvent most crowded buses. The problem is formulated as bilevel model, which upper-l...

Background: The inferior vena cava (IVC) dimensions represent the right ventricular preload, whereas the peak early mitral inflow wave velocity (peak E-velocity) represents the left ventricular preload. On the other hand, B-lines represent extravascular lung water. The aim of this study was to evaluate possible acute changes in the IVC dimensions, peak E-velocity, and number of B-lines during h...

The conventional sine wave oscillator circuits use phase shifting techniques that RC phase shift oscillator using op-amp in inverting amplifier introduces. Figure show a RC phase shift oscillator using Op-Amp with gain 5(Vo/Vi). My assumption : Circuit is generating a sine wave with a peak to peak voltage of 10v. Voltage stability, specifically the lack of, when using a resister divider is the ...

OBJECTIVE To assess the long axis function of both ventricles during the early neonatal period by using pulsed wave Doppler tissue (PWDT) echocardiography. DESIGN PWDT echocardiography was recorded from the lateral sites of the mitral and tricuspid annuluses and the tip of interventricular septum in 130 neonates within 24 hours after birth (day 0 group), in 135 neonates 1-7 days after birth (...
