Experimental Study of the Performance of a Novel Vertical-Axis Wind Turbine
Applied Sciences, 2020 Basic equations for estimating the aerodynamic power captured by the Anderson vertical-axis wind turbine (AVAWT) are derived from a solution of Navier–Stokes (N–S) equations for a baroclinic inviscid flow.

Experimental Investigation of Bladeless Power Generator from Wind-induced Vibration
International Journal of Renewable Energy Development, 2022 The power harvester unit from flow-induced vibration (FIV) was designed to harness energy from low flow velocity based on the magnetostrictive effect on the galfenol (Fe – Ga alloy) strip induced by the oscillating bluff body.

Analyzing coefficients of psychophysical power functions [PDF]
Perception & Psychophysics, 1993 Some mathematical properties of coefficients of power functions were analyzed. The size of correlations between intercepts (the logarithm of the coefficient) and exponents depends on the choice of unit of measurement of the physical stimuli. When the mean of logarithms of a set of responses is uncorrelated with the exponent, the absolute size of the ...
