Failure Diagnosis of V-Belt by Cross-Spectrum Method and Discriminant Function Approach.

Development of a diagnosis technique for failures of V-belts by a cross-spectrum method and a discriminant function approach

This paper describes the development of a failure diagnosis technique for V-belts through vibration monitoring. The V-belt vibration is monitored at a driven bearing body attached to a power transmission device. Seven basic causes of belt failure and their combinations are considered. Power spectra of the vibration data are calculated through noise reduction by a cross-spectrum method. Six para...

Electronic Transmission Wave Function of Disordered Graphene by Direct Method and Green's Function Method

We describe how to obtain electronic transport properties of disordered graphene, including the tight binding model and nearest neighbor hopping. We present a new method for computing, electronic transport wave function and Greens function of the disordered Graphene. In this method, based on the small rectangular approximation, break up the potential barriers in to small parts. Then using the f...

conceptual metaphor and the acquisition of english metaphorical competence by persian english majors: a cognitive linguistic approach

بنا براستدلال زبانشناسان شناختی ، اندیشه آدمی تا حدّ زیادی استعاری است: ما اندیشه ای را، و یا قلمرو مفهومی معیّنی را، بر حسب اندیشه و یا قلمرو مفهومی معیّن دیگری درک ویا تجربه می کنیم. موارد این نوع اندیشیدن ، که استعارات مفهومی خوانده می شوند، در زبان های گوناگون به صورت تعبیرات استعاری واقعیّت می یابند. به گمان بعضی از پزوهشگران زبان دوم، آموزش وفراگیری این گونه تعبیرات باید بخشی لازم از برنامه ه...
