The efficiency of rim-driven thrusters (RDT) has always been the focus attention in context energy conservation and environmental protection. A multi-parameter collaborative optimization framework is proposed to improve RDT based on response surface method (RSM). common structural parameters RDT, including pitch ratio, disk ratio rake angle, are selected as design variables carry out Box–Behnke...

Abstract. Recently, there has been an increasing emphasis in the Indirect bridge health monitoring method employing passing vehicles, which is regarded as one of most effective approaches damage screening. However, few researches have conducted on Drive-by inspection using vehicle displacement profile indicator due to challenges measurement and result accuracy. This paper proposes optimization ...
