We present some new criteria for the oscillation of even order dynamic equation[Formula: see text]on time scale T, where α is the ratio of positive odd integers a and q is a real valued positive rd-continuous functions defined on T.

We study the nonlinear forced dynamics of a bistable buckled beam. Depending on forcing frequency and amplitude, we observe three different regimes: (i) small intra-well oscillations in neighborhood one equilibria, (ii) transient snap-through ending into oscillations, (iii) persistent dynamic snap-through. build experimentally numerically phase-diagrams determining amplitude leading to each reg...

This paper investigates the possibility of converting vibrations to electricity. A numerical and an experimental study a magnetic levitation harvester are proposed. The system can be highly efficient when electrical parameters correctly tuned. Mechanical interaction is described by electromechanical coupling. Fixed value, linear nonlinear coupling models presented compared. It has been shown th...

Recently there has been a strong interest in cross-frequency coupling, the interaction between neuronal oscillations in different frequency bands. In particular, measures quantifying the coupling between the phase of slow oscillations and the amplitude of fast oscillations have been applied to a wide range of data recorded from animals and humans. Some of the measures applied to detect phase-am...

Low Frequency Oscillations (LFO) occur in power systems because of lack of the damping torque in order to dominance to power system disturbances as change in mechanical input power. In the recent past Power System Stabilizer (PSS) was used to damp LFO. FACTs devices, such as Unified Power Flow Controller (UPFC), can control power flow and increase transient stability. So UPFC may be used to dam...
