17 de abr. de 2024 · The phenomenon of coherence resonance (CR) in two typical kinds of fractional van del Pol oscillator is investigated. For the first model, the damping term of the ordinary van der Pol oscillator is replaced by a fractional-order damping.
1. Introduction. Blade vibration due to the operational harmonics in horizontal axis wind turbines is a problem that is usually analysed at the design stage of a blade. Wind turbine (WT) manuals [1], [2], [3] give a general explanation of the theoretical details of this phenomenon.
Hace 5 días · Building Oscillation Seismic Simulation, or BOSS, is an opportunity for learners to explore the phenomenon of resonance for different building heights while performing a scientific experiment that employs mathematical skills. They experience how structures behave dynamically during an earthquake.
Hace 2 días · This phenomenon is a called parametric resonance of the coupled system, which manifests itself as an energy transfer from one component to the other and vice versa. The speed and amplitude of the energy transfer depend essentially on the initial conditions.
28 de abr. de 2024 · Explore all metrics. Abstract. In the process of strip rolling, mill vibration induces vertical and horizontal displacements in the rolls and rolled parts, affecting the accuracy of the rolling analysis model.
30 de abr. de 2024 · LSPR, fundamentally an optical phenomenon, manifests as a synchronized oscillation of valence electrons within noble metals, leading to the absorption of light within the ultraviolet–visible (UV–vis) spectrum. This phenomenon arises from interactions between incident photons and the conduction band of a noble metal nanostructure.
30 de abr. de 2024 · For no other sensor, oscillations are present at this frequency, which points to an internal resonance phenomenon. This can be seen as a falsification and wrong representation of the 35 M Hz $35 \,\mathrm{M}\mathrm{Hz}$ signal component.
