A Sequential Quadratic Numerical Optimization Technique to Compute Critical Flutter Speeds
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]
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
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
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
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 ...

Study on vibration response characteristics of turbine blade for turbo-charger
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
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
Mistuning in bladed disks usually increases the forced response of the maximum responding blade leading to shortened component life in turbine engines.
