Physics to a Degree, 2018
A spatio-temporal method based on Robust Three-stage Dynamic Mode Decomposition (RTDMD) is proposed to improve the modal parameter estimation of synchrophasor data in the presence of noise, missing data and outliers.

Sensitivity and Nonlinearity of Thermoacoustic Oscillations
, 2018Nine decades of rocket engine and gas turbine development have shown that thermoacoustic oscillations are difficult to predict but can usually be eliminated with relatively small ad hoc design changes.

“Oscillating” Metallocene Catalysts: How Do They Oscillate?
Angewandte Chemie International Edition, 2002Based on the results of a series of propylene polymns. using oscillating metallocene catalysts of type [(2-Ar-indenyl)2ZrCl2] (Ar = C6H5 or 3,5-(t-Bu)2-4-MeO-C6H2) with various cocatalysts (MAO, TIBAl), the oscillating behavior of the zirconocenes is discussed with respect to the rac/meso stereochem. outcome of the obtained polypropylenes.

18. Operating Point on the Characteristic Curve By operating point on the characteristic curve is meant the point on the E c — I b curve of the audion about which the grid potential and space current vary. E c is the potential of the grid with respect to the filament. If a continuous negative potential such as Q Fig.

Oscillations in an Ensemble of Noninteracting Oscillators [PDF]
, 1989 The two most important cases in application are the almost trivial one in which all the oscillators are identical and the much more interesting one when the parameters of the oscillators are scattered either in frequency or in damping. The consideration of the behavior of an ensemble of identical noninteracting oscillators is the main subject of the ...

Evolution of Oscillation in a Quadrature Oscillator
2011 24th Internatioal Conference on VLSI Design, 2011The growth of oscillation in a quadrature oscillator that employs phase shifters in the coupling-path between a pair of LC-loaded negative resistance cores, is analyzed. Such an oscillator is known to have two stable modes of oscillation. Under a noise-initiated startup from an unstable initial condition, quasiharmonic assumption and the Method of ...

Oscillation death in coupled oscillators
Frontiers of Physics in China, 2009We study dynamical behaviors in coupled nonlinear oscillators and find that under certain conditions, a whole coupled oscillator system can cease oscillation and transfer to a globally nonuniform stationary state [i.e., the so-called oscillation death (OD) state], and this phenomenon can be generally observed.
