Abstract This contribution investigates the influence of outgassing processes on vibration behavior a hydrodynamic bearing supported turbocharger rotor. The examined rotor is radially by floating rings with outer squeeze-film damping and axially thrust bearings. Due to highly nonlinear properties, can be excited via lubricating film, which results in subsynchronous vibrations known as oil-whirl...

Malaysians were reported to have the most number of Facebook friends, spend more time on Facebook and might be addicted to Facebook as well. This paper explored Facebook usage pattern, motivations and psycho logical/behavioural factors affecting the users. A focus group study was first conducted to explo re motives to use Facebook and symptoms related to excessive Facebook usage. The themes eme...

Diamond-like carbon sDLCd films have always had high intrinsic stress due to their metastable structure and the fine balance between film density and bond stability. We show the effects of high intrinsic stress on the electron field emission performance, where a lower electric field for emission is recorded with increasing stress in the DLC films. In addition to examining “as deposited” films w...

Coherent perfect absorption (CPA) was introduced as a classical optics phenomenon of standing-wave by subwavelength film. In this paper, we develop theory CPA quantized standing waves taking account thickness the absorber. This approach allows us to merge all known quantum effects under single and introduce other regimes including NOON states with arbitrary number entangled photons, orthogonall...
