Dynamics of Periodic Impulsive Collision in Escapement Mechanism
Shock and Vibration, 2013 Among various non-smooth dynamic systems, the periodically forced oscillation system with impact is perhaps the most common in engineering applications. The dynamical study becomes complicated due to the impact.

Forced oscillation of piezoceramic cylinder with circumpolarization of material
Vestnik Samarskogo Gosudarstvennogo Tehničeskogo Universiteta. Seriâ: Fiziko-Matematičeskie Nauki, 2012 The nonstationary elasto-electrodynamics problem for an anisotropic piezoceramic cylinder of finite size with circumpolarization of material is considered for the case when the tangential stresses and the electric potential influence on the radial ...

Advanced Functional Materials, EarlyView.A three‐dimensional magnetic field sensor is realized in chiral W/CoFeB/MgO multilayers, where spin–orbit torques reversibly reconfigure homochiral stripe domains. The symmetry of the torque enables offset‐free in‐plane sensing, while the reproducible domain reconfiguration extends the linear out‐of‐plane range. An anomalous Hall readout delivers large‐

On the Effect of Forced-Oscillation Amplitude upon the Flow in a Cubic Cavity Heated Below
Journal of Fluid Science and Technology, 2013 The authors numerically investigate the forced-oscillation-frequency responses on flow and thermal characteristics of the thermal convection in a cubic cavity heated from below in the gravitational field, concerning global quantities such as spatially ...

AGU Advances, 2023 The most common explanation for the depletion of high frequency waves that defines low‐frequency earthquakes (LFEs) and very low‐frequency earthquakes (VLFEs) is that fault rupture and slip are slower than typical earthquakes. However, it is difficult to

Forced oscillations of nonspherical bubbles [PDF]
The Journal of the Acoustical Society of America, 1977 The oscillation of a gas bubble in liquid under externally applied sinusoidal pressure field is studied. When the applied pressure amplitude is small and the forcing frequency is not in the neighborhood of the resonance frequency of the bubble, the familiar linear results are obtained.

Historical Foundation and Practical Guideline for Ferroelectric Switching Kinetic Studies
Advanced Functional Materials, EarlyView.The P and U pulses in the conventional PUND measurements are not identical because of the interplay between switching current and the measurement circuit components. This circuit effect can lead to a shift in polarization transients and misinterpreted physics in the switching kinetics.
