The suspension system needs both an active mode and passive when the emergency rescue vehicle is running on a complex road. Therefore, active–passive composite actuator (APCSA) designed in this paper. Firstly, combined with computational fluid dynamics theory dynamic mesh technology, complete domain of original (PSA) simulated. Secondly, accordance simulation results consideration working condi...

The corrosion of metal pipes within water distribution systems posed great threats towards the quality and safety drinking water. In this study, quantity suspended particles alongside was investigated based on field experiments in a supply plant located Zhengzhou City Henan Province. changes were lab scale through analyzations about suspensions sedimentations using effluents from both conventio...

the fundamental natural frequency of vibration of an inflatable cantilever beam is computed from the system of the three equeations given for vibratory motion of the beam. the effect of various parameters is discussed, and it is shown that, as internal pressure increases, fundamental natural frequency will increase , indicating the stiffening characteristics of internal pressure. a single exper...

background: to explain the role of arthroscopic release in intractable frozen shoulders. we used different questionnaires and measuring tools to understand whether arthroscopic release is the superior modality to treat patients with intractable frozen shoulders. methods: between 2007 and 2013, in a prospective study, we enrolled 80 patients (52 females and 28 males) with recalcitrant frozen sho...
