Mistuning Identification of Bladed Disks Utilizing Neural Networks [PDF]
Mistuning affects forced response of bladed disks drastically; therefore, its identification plays an essential role in the forced response analysis of realistic bladed disk assemblies.

Study on identification of modal parameters of turbomachinery blade and impeller
To develop turbomachinery blades with high reliability, it is indispensable to verify the natural frequency, the damping, the resonant stress, etc. under operating condition, and utilize these data in the mechanical design of a new blade.

Intentional mistuning optimization of nonlinear mistuned bladed-disks
One major industrial challenge is to consider the detuning as a technological means to reduce the dynamical amplifications induced by mistuning. A full analysis of the detuning optimization of mistuned bladed-disks with finite displacements is carried out on a 12 bladed-disk finite element model.

Harmony and rhythm perception are often studied separately, yet both reveal a shared sensitivity to low‐order integer ratios. In harmony, intervals like the octave (2:1) and fifth (3:2) predict consonance and ease of encoding. In rhythm, patterns with simple ratios (e.g., 2:1, 3:2) are easier to perceive, reproduce, and remember.

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.

Blended Support of Attachment in Families: A Case Study of FamilieLink
ABSTRACT Attachment ruptures, when children struggle to trust in parental availability and support, are linked to increased risk of psychopathology. Preventing or repairing these ruptures is important for fostering secure attachment and promoting family mental health.

Analysis of a Turbine Bladed Disk With Structural and Aerodynamic Mistuning [PDF]
In this paper the effects of mistuning on the flutter stability of a turbine blade are analysed. Two types of mistuning are considered, frequency mistuning and aerodynamic mistuning. The study concentrates on the the first family of modes (1F, first flap)

Robustness Analysis of Intentional Mistuning Patterns in Randomly Mistuned Bladed Disk Assemblies [PDF]
It is known that bladed disks, which are usually designed as cyclically symmetric structures, undergo considerable amount of forced response amplitude magnification due to the phenomenon called mistuning.

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 ...

An anomalous dynamic phenomenon—unforeseen thickness elongation in biaxially prestretched dielectric elastomer actuators (DEAs) under sinusoidal voltage excitation—is investigated here. Unlike quasi‐static predictions where the material remains compressed throughout the cycle, this phenomenon exhibits alternating compression and elongation within each ...
