In this paper, the proposed control strategy for polypropylene production process prepared by liquid phase bulk method is simulated in the multifunction process control platform device. More specifically, for the polypropylene continuous reaction process with typical highly nonlinear, time-delay and complex characteristics, the ratio control system for feed flow and the temperature fuzzy controller...
To investigate the physiological and ecological characteristics of methangens in the steady-state of anaerobic baffled reactor (ABR), a laboratory-scale ABR with seven compartments was operated with molasses wastewater as substrate. Chemical analyses were done to evaluate digester performance. In parallel, Archael community dynamics were monitored by single strand conformation polymorphism (SSCP)...
A compact and low-profile wideband omni-directional microstrip patch antenna is proposed. The antenna is loaded by a novel spiral composite right/left-handed (CRLH) transmission line (TL), which is realized by replacing the interdigital capacitors of the conventional CRLH-TL with the spiral inductors. The antenna is composed with a four arms spiral line, a circle patch, four stubs connecting the patch...
