Rising demand, scarcity and lower production rate of crude oil has made fuel an unaffordable for a public passenger vehicle. In this scenario, an energy or fuel efficient system called hybrid system is the hardcore requirement of the automotive industry. The latest gasoline-electric hybrid and hydraulic hybrid systems are significantly more energy and fuel efficient than conventional vehicles. ...

Information technology and artificial intelligence technology hold great potential for enabling the distributed and intelligent fault diagnosis. Hydraulic motor is a common actuator having a high impact on the system performance. There has been significant work on fault detection and diagnosis for hydraulic motors. This paper presents a multi-agent framework for hydraulic motor fault diagnosis ...

The karst hydrological processes are the response of karst groundwater system to precipitation. This study provided a concept model of karst hydrological processes. The hydraulic response time of spring discharge to precipitation includes the time that precipitation penetrates through the vadose zone, and the subsequent groundwater pressure wave propagates to a spring outlet. Due to heterogenei...

Trees face the dilemma that achieving high plant productivity is accompanied by a risk of drought-induced hydraulic failure due to a trade-off in the trees' vascular system between hydraulic efficiency and safety. By investigating the xylem anatomy of branches and coarse roots, and measuring branch axial hydraulic conductivity and vulnerability to cavitation in 4-year-old field-grown aspen plan...
