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.

The location of an individual or a mobile terminal can be sensitive with regard to the privacy of an individual. Awarding the individual self-determination of the way position information is used will be crucial to the acceptance of the technology. This paper suggests a solution to how location data can be conveyed in privacy-friendly way using P3P combined with the PiMI method for data conveya...
