In this topical review, we present a brief overview of the different methods and measures to
detect the occurrence of critical transitions in complex systems. We start by introducing the …

Much of today's power grid was designed and built using technologies and organizational
principles developed decades ago. The lack of energy resources and classic power …

Military heavy vehicle drivers experience low-frequency vibrations that are associated with
fatigue, drowsiness, and other adverse health effects. The existing research papers focus on …

The water entry transient sound of a projectile can be used for early target detection in
passive sonar. Two detectors for the transient sound with low Signal to Noise Ratios (SNRs) …

Transient signals are universally characterized by a short duration and a broad spectrum
which are often present in various phenomena such as sudden acoustic pressure changes …

In this study, the effect of friction on the generation of dry-coupled Lamb waves is
experimentally investigated. Recurrence analysis is performed to analyze the complex …

Digital modulation identification is a challenging and important operation in the security
