Dynamic systems are faced with large vibration amplitudes if they operate near the resonance frequency of system or while passing through resonance. With a suitable external excitation reduction amplitude oscillation can be achieved. The analysis variable was first carried out on force driven single degree freedom harmonic oscillator. influence various parameters seen after mathematical transfo...

This study proposes a temperature model for the relaxation of magnetic nanoparticles and phase measurement method under mixing-frequency excitation field, which can improve accuracy measurements in nanothermometry. According to Debye-based magnetization nanoparticles, phases at mixing frequencies are used solve problem delay field high frequency. signal-to-noise ratio response weaken shift dete...

major proportion of intracellular calcium (ca 2+ ) is achieved through opening of calcium channels present in the plasma membrane which play an important role in regulating neuromuscular coordination and release of neurotransmitters from nerve terminals. blockade of these calcium channels adversely affect contractile process and release of neurotransmitters in majority of the neuromuscular prep...

The bifurcation analysis of a composite beam subjected to harmonic flapwise base excitation is studied when the ratio of flapwise and chordwise internal resonances is 1:2. Results are obtained by the numerical solution of modulation equations. Chracteristics of the response are investigated in terms of time history, phase portraits diagrams and bifurcation diagram of poincare maps. It is observ...
