In this paper, we propose a new fuzzy bang–bang relay controller (FBBRC). The bang–bang control systems use switching relays or hard limiter saturation functions with fixed parameters, and their input does not have the flexibility to control the non-linear system over its entire range of operation. The conventional fuzzy bang–bang controllers have an analog output and an external hard limiting ...

metal oxide surge arrester accurate modeling and its parameter identification are very important for insulation coordination studies, arrester allocation and system reliability. since quality and reliability of lightning performance studies can be improved with the more efficient representation of the arresters´ dynamic behavior. in this paper, big bang – big crunch and hybrid big bang – big cr...

background: pulmonary embolism (pe) is the most life-threatening form of venous thrombosis which causes the majority of mortalities in this category. obstructive sleep apnea (osa) has been indicated as one of the risk factors for thromboembolism because of hemostatic alterations. the present study was designed to seek for the relationship between osa and 30-day mortality of patients with pe. ma...
