Description:
The packing constant is an important and interesting geometric parameter of Banach spaces. Inspired by the packing constant for Orlicz sequence spaces, the main purpose of this paper is calculating the Kottman constant and the packing constant of the Cesàro-Orlicz sequence spaces ({\text{ce}}{{\text{s}}_\varphi }) defined by an Orlicz function φ equipped with the Luxemburg norm. In order to compute the constants, the paper gives two formulas. On the base of these formulas one can easily obtain the packing constant for the Cesàro sequence space cesp and some other sequence spaces. Finally, a new constant \widetilde D (X), which seems to be relevant to the packing constant, is given., Zhen-Hua Ma, Li-Ning Jiang, Qiao-Ling Xin., and Obsahuje seznam literatury

Subject:
EHD lubrication, micro dents, starvation, and fully flooded
Language:
English
Description:
This paper deals with an experimental study of lubricant film in an experimental device (tribometer). Lubricating film is formed between a glass disc and steel ball on which modification for friction surfaces have been made. The experiment is aimed at both fully flooded EHL lubrication regime as well as the starved. This document also deals with a comparison of micro dents passage through a contact at different degrees of slip. and Obsahuje seznam literatury
