When the sinusoidal grating of a "Gabor pattern" is drifted, the apparent position of the pattern shifts in the direction of motion [De Valois, R. L., & De Valois, K. K. (1991). Vernier acuity with stationary moving Gabors. Vision Research, 31, 1619-1626]. We investigated the underlying cause of this illusion by determining whether the effect is a consequence of the internal motion shifting the...

This research has been carried out to determine the marine propeller hydro-acoustic characteristics by Reynolds-Averaged Navier-Stokes (RANS) solver in both uniform and non-uniform wake flow at different operating conditions Wake flow can cause changes in pressure fluctuation and gas effect on propeller noise spectrum. Noise is generated by the induced trailing vortex wake and induced pressure ...

We study how reference dependence and loss aversion motivate highly experienced agents, professional basketball players. We find a very large “losing motivates” effect, an average team scores like a league leader when trailing by ten points and a bottom dweller leading by ten. Detailed data on players’ actions shows this effect comes through differential exertion of effort. Using betting spread...

Experimental results on trailing-edge (TE) noise from a NACA [Formula: see text] airfoil are presented for chord-based Reynolds number range between and text]. Far-field TE the baseline with straight serrations is measured varying text], angle of attack, serration shape flap angle. Additionally, aerodynamic coefficients boundary-layer parameters at also reported. To cover such broad range, two ...
