Wear in wind turbine pitch bearings—A comparative design study
Wind Energy, 2022 We tested two types of ball bearings with an outer diameter of 750 mm to learn more about the challenges of oscillating motions for pitch bearings. The experimental conditions are derived from aero‐elastic simulations, long‐term wind speed measurements ...

Quantitatively characterizing reflexive responses to pitch perturbations
Frontiers in Human Neuroscience, 2022 BackgroundReflexive pitch perturbation experiments are commonly used to investigate the neural mechanisms underlying vocal motor control. In these experiments, the fundamental frequency–the acoustic correlate of pitch–of a speech signal is shifted ...

An exploratory study of imagining sounds and “hearing” music in autism [PDF]
, 2020 Individuals with autism spectrum disorder (ASD) reportedly possess preserved or superior music-processing skills compared to their typically developing counterparts. We examined auditory imagery and earworms (tunes that get “stuck” in the head) in adults

Pitch-Responsive Cortical Regions in Congenital Amusia [PDF]
, 2015 Congenital amusia is a lifelong deficit in music perception thought to reflect an underlying impairment in the perception and memory of pitch. The neural basis of amusic impairments is actively debated. Some prior studies have suggested that amusia stems

Sensorless control of a power converter for a cluster of small wind turbines [PDF]
, 2016 This study presents a new sensorless control for small wind turbine clusters with a single power converter with a direct torque control algorithm. The proposed system consists of a wind farm connected to a back-to-back power converter that interfaces the

Training of Working Memory Impacts Neural Processing of Vocal Pitch Regulation [PDF]
, 2015 Working memory training can improve the performance of tasks that were not trained. Whether auditory-motor integration for voice control can benefit from working memory training, however, remains unclear.
