The nonlinear thermo-mechanic coupling effect refers to the interaction between dynamic characteristics of a dual-rotor system and thermal an intershaft bearing. In this paper, is proposed studied by operating radial clearance load A model under bearing established considering factors such as Hertzian contact force obtained based on responses system. Based this, proposed. attained according tem...

Using TCAD tools, many reliability issues can be studied quantitatively. Examples are hot carrier degradation of interfaces, threshold voltage shifts during NBTI stress, radiation effects and so...

State of the arts on guided-wave optical switch arrays are reviewed. In this paper, electro-optic Ti:LiNbO3 devices are mainly described in comparison with crosspoint switch element structures and switch array architectures. Packaging technologies and stability problems are discussed for practical system applications. Recent development on other materials such as semiconductor waveguides, therm...

A thermally fixed photorefractive Bragg grating is written in a single-mode Ti:Fe:Er:LiNbO3 channel waveguide and used to develop a distributed feedback-distributed Bragg reflector coupled cavity laser with a second broadband dielectric cavity mirror. The optically pumped (lambda(p) = 1480 nm, P = 130 mW) laser emits in single-frequency operation as much as 8 mW at lambda = 1557.2 nm with a slo...

Even under normal operating conditions, power devices are subject to temperature changes that generate high level of stress repeatedly causes mechanical breakdown. In this context thermomechanical simulations are necessary to predict life time and guarantee a longer lifespan. This paper aims to modeling electro-thermo-mechanical behavior of a vertical power transistor for predicting the influen...

The recycling of sodium borohydride poses a huge challenge to the drive towards hydrogen economy. Currently, mechano-chemical, thermo-chemical and electrochemical are only reported methods metaborate into borohydride. Much attention has been devoted mechano-chemical reduction, but little focus methods. This review describes behaviour (BH4−) (BO2−) anions in alkaline solutions. BH4− is stabilize...

The electro-thermo-convection of a dielectric liquid in horizontal capacitor is investigated under the autonomous charge injection from cathode and heating above. In case DC electric field, linear stability analysis carried out, thresholds monotonic oscillatory instability are determined. finite difference method used for numerical simulation nonlinear behavior electro-thermo-convective pattern...
