A Modal Interpretation for Aeroelastic Stability Enhancement of Mistuned Bladed Disks
Aerospace, 2022 Understanding the mechanism of the aeroelastic stability improvement induced by mistuning is essential for the design of bladed disks in aero-engines. In this paper, a quantitative interpretation is given. It starts by projecting the mistuned aeroelastic

Temporal deployment of attention in musicians: Evidence from an attentional blink paradigm
Annals of the New York Academy of Sciences, Volume 1530, Issue 1, Page 110-123, December 2023., 2023 Music training improves perceptual and cognitive skills, which may transfer to unrelated non‐musical domains. The cognitive processes and neural mechanisms enabling this transfer have yet to be discovered. Combining scalp recording of neuroelectric brain activity with an attentional blink paradigm, we provide evidence that music training improves the ...

Subjectively preferred octave size is resolved at the late stages of cerebral auditory processing
European Journal of Neuroscience, Volume 58, Issue 7, Page 3686-3704, October 2023., 2023 Human listeners prefer octaves slightly larger than 2:1. (a) and (b) Participants categorized compressed m90 and mathematical mat octaves as ‘low’, slightly enlarged ref as ‘good’ and oversized p90 as ‘high’. (c) In event‐related brain potentials measured during categorization, ref and mat differed late, after >500 ms from tone onset.

The neurobiology of vocal communication in marmosets
Annals of the New York Academy of Sciences, Volume 1528, Issue 1, Page 13-28, October 2023., 2023 The common marmoset (Callithrix jacchus) is an increasingly popular animal model for the study of vocal communication. Here, we review the neurobiology underlying this primate's vocal communication system focusing on brain networks of vocal perception and production.

Nihon Kikai Gakkai ronbunshu, 2016 Although bladed disks of turbomachinery are nominally designed to be cyclically symmetric (tuned system), the vibration characteristics of all blades on a disk are slightly different due to the manufacturing tolerance, the deviation of the material ...

High order sensitivity analysis of a mistuned blisk including intentional mistuning
Journal of Theoretical and Applied Mechanics, 2017 Small deviations between turbine blades exist due to manufacturing tolerances or material inhomogeneities. This effect is called mistuning and usually causes increased vibration amplitudes and also a lower service life expectancy of bladed disks or so called blisks (bladed integrated disk).

Harmonic Mistuning of Blisks [PDF]
PAMM, 2015 AbstractThe paper describes a new method to calculate the maximum amplificationof blade vibrations of a bladed disk or blisk subject to manufacturing tolerances. Two effects of mistuned blisks are analyzed in this paper. The separation of two orthogonal nodal diameters are shown and described in detail.
