A Sequential Quadratic Numerical Optimization Technique to Compute Critical Flutter Speeds

open access: yesInternational Journal for Numerical Methods in Engineering, Volume 127, Issue 17, 15 September 2026.
ABSTRACT A stable sequential quadratic numerical optimization technique is proposed to compute critical flutter speeds without resorting to complex algebra. The solution of the traditional eigenproblem stated in the frequency domain, and whose complex conjugate eigenvalues provide insights on the stability of the dynamic aeroelastic response, is ...

The effects of mistuning on Fan flutter [PDF]

open access: yes, 2015
peer reviewedThe aim of this paper is to study the effects of mistuning on fan flutter. The computations are based on a three-dimensional, whole assembly, timeaccurate, viscous, finite-volume compressible flow solver.

The oscillatory response of the electroretinogram and neuronal adaptation

open access: yesActa Ophthalmologica, Volume 104, Issue 6, Page 616-637, September 2026.
Abstract After more than 50 years, there still remains a challenge and an interest to know more as well as extend and deepen our understanding of the small rapid wavelets, the oscillatory potentials (OPs), of the electroretinogram (ERG) and the neuronal adaptation of the retina.

Aerodynamic Mistuning of Structurally Coupled Blades

open access: yes, 2008
This paper discusses the impact of aerodynamic mistuning in the context of a structurally coupled blade system. The aerodynamic mistuning assumes a difference in blade loading (between adjacent blades) but no change in eigenfrequency or modeshape.

Study on optimal design of mistuned bladed disk

open access: yesNihon Kikai Gakkai ronbunshu, 2018
Although, in designing blades, it is assumed that all blades on a disk are identical (tuned system), the vibration characteristics of the blade is slightly different due to the manufacturing tolerance, the deviation of the material property, and so on ...

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.

Study on vibration response characteristics of turbine blade for turbo-charger

open access: yesNihon Kikai Gakkai ronbunshu, 2019
In the mechanical design of a turbine blade for an automotive turbo-charger, it is pointed out that the mistuning effect caused by the difference of the casting condition should be considered.

Enhanced Contour‐Deviant Mismatch Negativity and Mnemonic Representations in Older Musicians

open access: yesEuropean Journal of Neuroscience, Volume 63, Issue 12, June 2026.
Data showed enhanced MMN amplitudes in aging adult musicians compared with nonmusicians. Given that enhancements in MMN responses may be an indicator of preserved sensory processing in aging, music training may insulate age‐related decreases in sensory processing through preserved fidelity of encoding auditory information.

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.

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.
