Rings are widely used in mechanical equipment and their fitness may damage under severe vibration. In these structures functionally graded rings can be used to optimize the resistance, energy consumption and better fitness. ...

The raw milk is an important basic material for many food products. Fresh milk must be cooled immediately after milking to keep high quality and process ability. In this work the overall heat transfer coefficients of the ...

Bubble coalescence is an important stage of foaming process. A goal of foaming is to produce numerous, uniform-size bubbles. Therefore suppression of bubble coalescence is desirable during foaming process. For stationary ...

Cold expansion is an effective technique of inducing favorable compressive residual stresses around fastener holes essentially vital for improving fatigue performances of aircrafts. The benefit is caused by the magnitude ...

This article describes the heat and mass transfer as well as the entropy generation in an unsteady double-diffusive natural convection in the presence of an external magnetic eld, Soret and Dufour e ects. The analysis ...

This paper developed a new mathematical model to investigate the heat transfer as well as wick thickness of a heat pipe. The model was set up by conservative equations of continuity, momentum and energy in the thermal ...

In principal, a proper analysis of the dynamic response of a structure can provide general indicators of its operational conditions. When the dynamic response changes due to a variation of the physical properties of a ...

In this paper, the robot-assisted interventions for a pair of fraternal twins with autism, one of whom is high-functioning and the other low-functioning is presented.  Since many genetic and environmental factors were the ...

A new approach for numerical solution of sinusoidal steady stateMaxwell's equations is developed. This approach is based on Yee'smethod, and can be applied on unstructured grids. A case problemwith available analytical ...

In friction stir spot welding (FSSW) process the welding parameters (the tool rotational speed, the tool plunge depth and the stirring time) effect the nugget formation in high density polyethylene (HDPE) sheets. The size ...
