This paper investigates a cantilever beam nonlinear dynamic behaviour, on which the nonlinearity is introduced with permanent magnet interactions or non-holonomic contact. The experimental time domain responses obtained from non-zero initial conditions are measured using laser profilometer, conventionally adopted for product shape detections in online industrial applications. Fourier transform,...

Quantum coherence is a fundamental property of quantum systems, separating from classical physics. Recently, there has been significant interest in the characterization as resource, investigating how can be extracted and used for technological applications. In this work, progress research reviewed, focusing particular on recent experimental efforts. After brief review underlying theory, main pl...
