We study an optomechhanical device supporting at least three optical modes in the infrared telecommunication band and mechanical vibration modes. model coherent driving of each mode, independently other, to obtain effective Hamiltonian showing different types parametric processes allowed device. propose a bichromatic scheme, lossy cavity regime, under mean field approximation, that provides qua...

An investigation into the vibration characteristics of a ‘Roots and Claws’ based dry vacuum pump under different operating conditions was conducted. An AutoRegressive (AR)-based condition monitoring algorithm was developed and tested on both a fault-free and a pump with an implanted ceramic bearing with an inner race defect at the High Vacuum (HV) end. The investigation provided some in-depth u...

dynamic behavior of the wind-excited-benchmark-building using semi-active electromagnetic friction dampers (saemfds), with modulated homogeneous friction algorithm is presented. the performance of the benchmark building is studied under across wind loads by installing the saemfds with smooth boundary layer semi-active friction (sblsaf) algorithm. the governing equations of motion are solved by ...

In this work parametric reduced order models (pROMs) for cracked shells are developed and applied to crack detection problems. Mesh morphing is employed allow parameterization of the with respect location size, while a clustering approach adopted partition parameter space in sub-domains, which efficient local (ROMs) constructed. Subsequently, proposed ROMs as forward simulators within an invers...

Vibrations cause many problems such as displacement, distortion, and defocusing in microscopic imaging systems. Because vibration errors are random direction, amplitude, frequency, it is not known which aspect of the image quality will be affected by these to what extent. Polarization parametric indirect (PIMI) a technique that records polarization parameters conventional wide-field reflection ...
