The articles in this special issue attest to the fact that we are in the early stages of a scientific revolution in marine microbiology that is being fueled by vast quantities of new information deriv...
Nonlinear internal solitary waves generated within Luzon Strait move westward across the northern South China Sea, refract around Dongsha Atoll, and dissipate on the Chinese continental shelf after a ...
Backgrounds and Objectives:A number of different technologies have recently been studied todetermine the best use of biogas, however, to choose optimize technologies of using biogas for energy recover...
In this paper, we propose a novel prevention strategy to alert citizens when water is contaminated by estro-gen. Epidemiological studies have shown that chronic exposure to high blood level of estroge...
In this work, nonlinear and multi-objective mathematical models were developed to determine the process parameters corresponding to optimum weld pool geometry. The objectives of the developed mathemat...
非自由切削是影响微细切削加工的重要效应之一。针对微细切削条件下刀具圆弧刃区切削干涉作用显著增强的特点,通过单元刀具之间切削干涉对切屑流动方向的影响分析,建立了圆弧刃刀具的排屑方向干涉模型。应用Stabler法则和最小能量耗散原理确定出圆弧刃刀具作纵向进给的切屑流动方向、等效切削刃、流屑角和非自由系数。选取不同进给量和切削深度的组合对以上非自由切削特征参数进行了数值预报,预报结果可用于微细切削非自由...
