Distinguishing modulated oscillations from coloured noise in multivariate datasets
* Permanent address: Space Science Department, Rutherford Appleton Laboratory, Chilton, Didcot, OX11 0QX, UK and Department of Physics, University of Oxford, UK (e-mail: m.allen16physics.oxford.ac.uk) Abstract. Extended empirical orthogonal functions (EEOFs), alternatively known as multi-channel singular systems (or singular spectrum) analysis (MSSA), provide a natural method of extracting osci...
متن کاملModulated oscillations in many dimensions.
Modulated oscillations are described via their time-varying amplitude and frequency. For multivariate signals, there is structure in the signal beyond this local amplitude and frequency defined for each signal component, in turn describing the commonality of the components. The multivariate structure encodes how the common oscillation is present in each component signal. This structure will als...
متن کاملPhase multistability of self-modulated oscillations.
The paper examines the type of multistability that one can observe in the synchronization of two oscillators when the systems individually display self-modulation or other types of multicrest wave forms. The investigation is based on a phase reduction method and on the calculation of phase maps for vanishing and finite coupling strengths, respectively. Various phase-locked patterns are observed...
متن کاملPeriodic Oscillations in the Analysis of Algorithms and Their Cancellations
A large number of results in analysis of algorithms contain fluctuations. A typical result might read “The expected number of . . . for large n behaves like log2 n + constant + delta(log2 n), where delta(x) is a periodic function of period one and mean zero.” Examples include various trie parameters, approximate counting, probabilistic counting, radix exchange sort, leader election, skip lists,...
متن کاملAchieving modulated oscillations by feedback control.
In this paper, we develop an approach to achieve either frequency or amplitude modulation of an oscillator merely through feedback control. We present and implement a unified theory of our approach for any finite-dimensional continuous dynamical system that exhibits oscillatory behavior. The approach is illustrated not only for the normal forms of dynamical systems but also for representative b...
