To illustrate the underlying principle and algorithm, a detailed study is made on the K-band ranging （KBR） assembly, which includes the measurement principles, modeling of noises, the generation of Level 1A data from that of Level 0 as well as Level IA to Level IB data processing.展开更多

The title of my presentation ＂Changing Patterns in Textile End-Use＂ is aimed at increasing awareness of future changes and challenges as well as delivering a tool to better understand existing dynamics. Understanding the history of textile dynamics is a basic prerequisite to draw conclusions for the future development.展开更多
