Abstract As an important power component of the material conveying system, motor will inevitably cause vibration mechanical structure when rotating, thus affecting stable operation motor. Most systems have high requirements for level, and usually take performance electrical as evaluation criteria same level. A nonlinear terminal sliding mode controller is proposed to solve phase delay problems ...

An experimental study concerning particle behaviors in a horizontal dilute swirling flow pneumatic conveying was performed. Measurements of particle velocities and concentration profiles have been carried out using the photographic image technique. From the experimental results, it is found that mean particle velocity of swirling flow pneumatic conveying is lower than that of conventional pneum...

In dialogue systems, conveying understanding results of user utterances is important because it enables users to feel understood by the system. However, it is not clear what types of understanding results should be conveyed to users; some utterances may be offensive and some may be too commonsensical. In this paper, we explored the effect of conveying understanding results of user utterances in...

the harmony search algorithm is applied to optimum designs of a functionally graded (fg)-carbon naotubes (cnts)-reinforced pipes conveying fluid subjected to moving load. the structure is modeled by reddy cylindrical shell theory and the motion equations are derived by hamilton's principal. based on differential quadrature method (dqm), the dynamic displacement of system is derived. the le...

Dense phase pneumatic conveying has been investigated through simulation, using a discrete element approach for the granular particles and a finite difference method for the pressure field. Both horizontal and vertical conveying are studied and compared. Studies of single plugs or slugs promise to give insight into the performance of pneumatic conveying systems.
