Abstract: Ambient air fine particulate matter (PM2.5) is a kind of instantaneous variation of space and time that cannot be repeated. In the process of fluid sampling analysis of real-time data, there are too many variables and too fast component changes for the laboratory to undertake such tests. The fast automatic monitoring technology provides real-time m... Show More

Abstract: Cam-follower mechanism efficiency in production of desired motions has been proved along the history of space missions. In this paper, according to pre-specified spatial condition of wide temperature variations between -100 and +120 Celsius degrees, some new and innovative cam-follower profile designs are presented. In the first follower mechanism,... Show More
