From Stability to Chaos: A Complete Classification of the Damped Klein‐Gordon Dynamics
Mathematical Methods in the Applied Sciences, EarlyView.ABSTRACT We investigate the transition between stability and chaos in the damped Klein‐Gordon equation, a fundamental model for wave propagation and energy dissipation. Using semigroup methods and spectral criteria, we derive explicit thresholds that determine when the system exhibits asymptotic stability and when it displays strong chaotic dynamics ...

Velocity Spectrum Imaging Using Velocity Encoding Preparation Pulses
Magnetic Resonance in Medicine, EarlyView.ABSTRACT Purpose The goal of this article is to introduce a technique to measure the velocity distribution of water inside each voxel of an MR image. The method is based on the use of motion sensitizing gradients with changing first moment to encode velocity. As such, it is completely non‐invasive and requires no contrast injections.

International Journal of Mechanical System Dynamics, EarlyView.ABSTRACT An experimental campaign was undertaken to demonstrate the applicability of the Bouc–Wen hysteretic model to describe the hysteretic system of the recent Framatome dimple‐less spacer grid design for Pressurized Water Reactors. The experimental setup subjected a reduced‐length fuel rod, supported at both ends by dimple‐less grids, to forced ...

In‐situ Analysis of Paste Properties in Resonant Acoustic Mixers for Quality Monitoring
Propellants, Explosives, Pyrotechnics, EarlyView.Quality monitoring is important to ensure manufacturing robustness and achieve consistent properties. For the emerging technology resonant acoustic mixing, this work uses motor data to detect differences in particle content in formulations and variations in powder feedstock properties.
