This paper proposes a weak signal detection strategy for rolling element bearing fault diagnosis by investigating a new mechanism to realize stochastic resonance (SR) based on the Woods Saxon (WS) potential.
Furthermore, the influence of time delay and feedback intensity on the SR phenomenon is analyzed, and by selecting appropriate time delay, feedback intensity and re-scaling ratio with genetic algorithm, the SR can be produced to realize the resonance detection of weak signal.
This study could help realizing Fano resonance based photonic devices using simple and antisymmetric nanostructures.
The mechanism based on different waveguide modes paves a new route to realizing Fano resonance in the plasmonic waveguide system.
Zhang et al. firstly realized Fano resonance and EIT in a plasmonic nanostructure with a bright and dark element in one plane [22].
The perturbation-based modal solution furnishes, first, explicit formulae for the parameter combinations which realize the internal resonance conditions and, second, asymptotic approximations of the resonant frequencies and modes.
The stack of a half nanoring creates a path for realizing different Fano resonance modes in the plasmonic resonant system.
A novel structure with bilayer hybrid graphene/metal (G/M) gratings to realize tunable double Fano resonances has been proposed.
The sensor is consisted of a PMMA photonic ring waveguide which can produce resonance spectrum to realize pressure measurement.
And the preferential parameter of transducer was adjusted to realize the degeneration between the resonance frequencies of two vibration modes of stator.
The chapter highlights major obstacles arising in the clinical setting, emphasizing the importance of overcoming these obstacles in order to realize the full potential of magnetic resonance spectroscopy.
