In order to improve the automation and reliability of the mechanized transplanting, a vegetable seedling automatic conveying system was designed. The functional execution component of the system consists of a tank-wheel storage seedling mechanism, a seedling tray conveyor, and a hanging cup circulating conveying mechanism. Combined with the communication technology between host computer and programmable...
It had been U.S. Environmental Protection Agency(EPA) suggested the 16 polycyclic aromatic hydrocarbons(PAHs) must take priority of control due to potential harm to people's health. The extensive amount of data show the part of PAHs source from the utilization of the coal. During the coal conversion process, PAHs released may be divided into two categories according to their formation pathways. One...
In this paper, a novel sensor fault detection and identification technique based on kernel principal component analysis (KPCA) and its fast data reconstruction is presented. Although it has been proved that KPCA shows a better performance for sensor fault detection, the fault identification method has rarely been developed. Using the fast data reconstruction based on distance constraint, we employ...
