Corrosion is a serious problem on the first atmospheric distillation unit when the plant refines high-acid crude oil from Shengli Oil Field. To measure and predict the corrosion and related factors is significant tasks in refinery. The GM(1,1) model only can predict the sequence of exponential law, scribe the monotonic change event. Took acid value as sample, used the data from the first to 6th month,...
Microbial growth is a very complex non-linear system, so there is important engineering significance to study its growth model in holding back biofouling, eliminating biofouling and preventing corrosion. In this paper, a non-linear dynamic model of microbial growth was built based on the theories of the diffusion response of thermodynamics and the chemotactic response of biology. The model involves...
The lay length of metallic wire ropes is an important dimensional quantity whose analysis is useful to highlight rope deformations due to distributed damages. This paper describes a measurement system that is based on a video camera and on an offline processing algorithm. The camera acquires an image sequence of the running rope; then, an image processing algorithm extracts the rope contour and measures...
