Abstract

The small-sized herringbone groove journal bearing (HGJB), i.e., so-called “magnetic bearing,” filled with Newtonian ferrofluid lubrication is investigated via finite difference analysis (FDA), with consideration of cavitation zones in HGJB. The FDA starts with constructing the mass flux equations of the HGJB filled with ferrofluid. Discretization for FDA is next performed over the bearing clearance domain, from which algebraic finite difference equations based on the mass flow balance over the clearance domain are derived. Solving the equations, rotordynamic coefficients, cavitation zones, and side leakage rate are successfully predicted to show effectiveness in enhancing bearing performance by ferrofluid.

Abstract

A new doubled electrode-layered liquid crystal lenticular lens (LC lens) with multi-electrodes is proposed to realize an auto-stereoscopic display for mobile devices of OLED panel. The analyses of crosstalk show the quality of 3D display in vertical and horizontal screen as 0% and 23%. [ABSTRACT FROM AUTHOR]

Abstract

Physical geography is a branch of science devoted to the study, utilization and transformation of nature. To utilize and transform nature, we, of course, have to understand the rules in regard to the origin, development and distribution of nature. On the surface of the earth and in the space adjacent to the earth where the lithosphere, atmosphere and hydrosphere meet and mix with one another, nature which consists of such essential-elements as topography, climate, ocean and seas, soil, plants and animals, is an intrinsically well-integrated entity. To understand this intrinsically well-integrated entity calls for analysis as well as synthesis, separate studies of the origin, development and distribution of the different constituent-elements as well as an overall study of the origin, development and distribution of the whole entity., Trans.of Ti-l1 Chih-shih (Geographic Knowledge) (China), n10 p433-436, 6 Oct 59
