Time resolved tracking of a sound scatterer in a turbulent flow: non-stationary signal analysis and applications [PDF]
, 2001 It is known that ultrasound techniques yield non-intrusive measurements of hydrodynamic flows. For example, the study of the echoes produced by a large number of particle insonified by pulsed wavetrains has led to a now standard velocimetry technique. In

Cooling of a levitated nanoparticle with digital parametric feedback
, 2019 The motion control of a levitated nanoparticle plays a central role in optical levitation for fundamental studies and practical applications. Here, we presented a digital parametric feedback cooling based on switching between two trapping laser intensity

Periodic orbits, basins of attraction and chaotic beats in two coupled Kerr oscillators [PDF]
, 2011 Kerr oscillators are model systems which have practical applications in nonlinear optics. Optical Kerr effect i.e. interaction of optical waves with nonlinear medium with polarizability $\chi^{(3)}$ is the basic phenomenon needed to explain for example ...

Fission widths of hot nuclei from Langevin dynamics [PDF]
, 2001 Fission dynamics of excited nuclei is studied in the framework of Langevin equation. The one body wall-and-window friction is used as the dissipative force in the Langevin equation.

Translational Motion Compensation of Space Micromotion Targets Using Regression Network
IEEE Access, 2019 The high-speed translational motion of space targets will cause the micro-Doppler to shift, tilt, and fold, which brings great difficulty to the extraction of micromotion features.

Linear modal analysis of L-shaped beam structures: parametric studies [PDF]
, 2012 Linear modal analysis of L-shaped beam structures indicates that there are two independent motions, these are in-plane bending and out of plane motions including bending and torsion. Natural frequencies of the structure can be determined by finding the

Backlund transformations and Hamiltonian flows
, 2013 In this work we show that, under certain conditions, parametric Backlund transformations (BTs) for a finite dimensional integrable system can be interpreted as solutions to the equations of motion defined by an associated non-autonomous Hamiltonian.

On the solutions and stability for an auto-parametric dynamical system
Archive of applied mechanics (1991), 2022 The main goal of this study is to look at the motion of a damped two degrees-of-freedom (DOF) auto-parametric dynamical system. Lagrange’s equations are used to derive the governing equations of motion (EOM).
