Lubricating oil flow characteristics are the primary concern in main reducer of light helicopters. To improve lubricating performance reducer, a special lubrication system is innovatively constructed by adding two oil-guiding tubes to hub output gear, and influence investigated through CFD (computational fluid dynamics) techniques. A model gearbox integrated with VOF (volume fluid) technique wa...

In order to construct a system with multiple-degrees-of-freedom by using the motors one degree of freedom, same number as freedom is necessary. On other hand, because spherical motor has three degrees it possible realize and, therefore, can reduce size system. A speed reducer necessary increase output torque for We proposed capable decelerating in ratio independent on rotation axis and demonstr...

In this paper, a Rough-Neuro hybrid methodology of the diagnostic process is proposed as a means to achieve accurate diagnosing of Erythemato-Squamous diseases. The methodology incorporates a two-stage hybrid mechanism. Rough sets Johnson Reducer for reduction of relevant attributes and artificial neural network Levenberg-Marquardt algorithm for the classification of the diseases. The model ach...

A significant part of observations at the Russian 6 m telescope is carried out using the SCORPIO multi-mode focal reducer. During the past ten years, a lot of scientific data have been collected using observations in the direct imaging, slit spectroscopy and Fabry-Pérot interferometry modes. Some results of these observations are considered in this review. We also present a short description of...

In this paper, we propose a simple (alignment-free) and low-cost microfabrication technique of dual opposite silver electrodes having each separated electrical contact pad inside a microchannel using multiphase laminar flow with density difference, without any photolithographical processes. The electrode patterns were realized by chemical deposition at the interface between a silver electroless...

R efractory angina pectoris is a debilitating clinical condition that has typically been used to describe a subset of patients with chest pain syndrome on maximally tolerated antianginal medical therapy, demonstrable myocardial ischemia, and no coronary revascularization options (1). A multitude of novel treatment options directed at patients with refractory angina, ranging from interventional ...
