Analysis of Lur’e dominant systems in the frequency domain [PDF]
Automatica, 2018 Frequency domain analysis of linear time-invariant (LTI) systems in feedback with static nonlinearities is a classical and fruitful topic of nonlinear systems theory. We generalize this approach beyond equilibrium stability analysis with the aim of characterizing feedback systems whose asymptotic behavior is low dimensional.

Review of Dominant Frequency Analysis in Atrial Fibrillation [PDF]
Journal of Atrial Fibrillation, 2009 Significant advancements have been made in the technology and approach to catheter ablation of atrial fibrillation (AF). Pulmonary vein isolation has emerged as the dominant strategy in this procedure and has fueled innovations in catheter design as well as various mapping and navigation systems.

Subjective dominance as a basis for selecting frequency weightings [PDF]
The Journal of the Acoustical Society of America, 2016 The objective of this paper is to propose and illustrate a simple approach for the selection of frequency weightings for the assessment of environmental and transportation noise. In recent years, the A-frequency weighting has become almost universal except where existing standards and regulations mandate the use of alternative weightings and/or ...
