Dynamic characteristics of vibration localization of mistuned bladed disk due to shroud and blade damages

open access: yesJournal of Low Frequency Noise, Vibration and Active Control
Dynamic behaviors of turbine blades are important for the dynamic design of whole-bladed disk systems. The bladed disk systems with shrouds are used to achieve advanced functions in operation.

Vibration Characteristics of Rotating Mistuned Bladed Disks considering the Coriolis Force, Spin Softening, and Stress Stiffening Effects

open access: yesShock and Vibration, 2019
Bladed disks of engine rotors usually operate at harsh conditions of high rotating speeds, which may lead to nonnegligible rotordynamic effects, including Coriolis force, spin softening, and stress stiffening effects.

Mistuning analysis of bladed disk consisting of directionally solidified blade (Vibration response analysis by use of response surface method and FMM)

open access: yesNihon Kikai Gakkai ronbunshu, 2014
Recently, DS (Directionally Solidified) and SC (Single Crystal) alloys have been widely applied for gas turbine blades instead of CC (Conventionally Casting) alloys.

Real‐time electron spectrometer utilizing a permanent magnet and diode detector array

open access: yesMedical Physics, Volume 52, Issue 10, October 2025.
Abstract Background Magnetic spectrometers have been previously described for measuring energy spectra of therapeutic electron beams. However, challenges for clinical utilization have been their size, weight, and limited real‐time capabilities. Development of a compact, lightweight, and inexpensive device with real‐time readout will make an electron ...

On Antiresonance in the Forced Response of Mistuned Bladed Disks

open access: yesShock and Vibration, 2003
Mistuning in bladed disks usually increases the forced response of the maximum responding blade leading to shortened component life in turbine engines.

Study on vibration characteristics of steam turbine vanes with large capacity (Vibration response characteristics of half ring structure)

open access: yesNihon Kikai Gakkai ronbunshu, 2017
A vane used in a low pressure end of steam turbine is usually fixed to an inner shroud and an outer ring by welding both ends. In such a vane structure, the damping in loading operation is comprised of the material damping and the aerodynamic damping ...

Auditory change detection in musically trained adolescents and young adults: An EEG–fMRI study

open access: yesAnnals of the New York Academy of Sciences, Volume 1550, Issue 1, Page 199-205, August 2025.
Electroencephalography (EEG) and functional magnetic resonance imaging (fMRI) were used to examine auditory deviance detection in musically trained and untrained 16–20‐year‐olds. Participants passively listened to a sequence of major chord standards and minor chord deviants during separate EEG and fMRI sessions.

Effect of mistuning on the detection of a tone masked by a harmonic tone complex. [PDF]

open access: yesPLoS ONE, 2012
The human auditory system is sensitive in detecting "mistuned" components in a harmonic complex, which do not match the frequency pattern defined by the fundamental frequency of the complex.

Quantum Powers and Primitive Ontology

open access: yesPhilosophy Compass, Volume 20, Issue 8, August 2025.
ABSTRACT This article surveys recent work on primitive ontology (PO) approaches to quantum mechanics, focusing on proposals that seek to integrate this approach with the metaphysics of causal powers. PO approaches aim to provide a clear metaphysical picture in which the world consists of local entities such as particles, matter density fields or ...
