A unitary model of auditory frequency change perception.

Changes in the frequency content of sounds over time are arguably the most basic form of information about the behavior of sound-emitting objects.In perceptual studies, such changes have mostly been investigated separately, as aspects of either pitch or timbre.Here, we propose a unitary account of "up" and "down" subjective judgments of frequency c

Backstepping-Based Inverse Optimal Attitude Control of Quadrotor

Abstract Input saturation must be SAMSUNG BRB260031WW/EU Integrated No Frost 70/30 195L Fridge 74L Freezer taken into account for applying rapid reorientation in the large angle manoeuvre of a quadrotor.In this paper, a backstepping-based inverse optimal attitude controller (BIOAC) is derived which has the property of a maximum convergence rate in
