A numerical study of an inline oscillating cylinder in a free stream [PDF]

open access: yes, 2011
Simulations of a cylinder undergoing externally controlled sinusoidal oscillations in the free stream direction have been performed. The frequency of oscillation was kept equal to the vortex shedding frequency from a fixed cylinder, while the amplitude ...

HIGH AND LOW FREQUENCY OSCILLATIONS IN DRUG EPIDEMICS [PDF]

open access: yesInternational Journal of Bifurcation and Chaos, 2006
We extend the two-dimensional model of drug use introduced in [Behrens et al., 1999, 2000, 2002] by considering two additional states that represent in more detail newly initiated ("light") users' response to the drug experience. Those who dislike the drug quickly "quit" and briefly suppress initiation by others.

Low frequency oscillations of the magnetosphere [PDF]

open access: yes2014 XXXIth URSI General Assembly and Scientific Symposium (URSI GASS), 2014
Sudden pulses in the model solar wind sets the Earth's magnetosphere into damped oscillatory motions. A simple model is capable of explaining many of the basic properties of these oscillations, giving scaling laws for their characteristics in terms of the parameters of the problem, such as the Solar wind momentum density. The period of the oscillations,

Identification of low frequency oscillation modes in large transmission systems

open access: yesRevista Facultad de Ingeniería Universidad de Antioquia, 2017
There is a typical dynamical performance associated with every system. Oscillations are phenomena inherent to dynamical systems and the analysis of such phenomena is a fundamental issue for understanding the dynamical behavior of a particular system ...
