Furthermore,choosing a range of proper values for carcass stiffness is very essential for both tire safety and effective driving action. In this work,an elaborated 3D model fully compliant with the geometrical size of radial tire 185/60 R15 is worked up, for evaluating the effects of components properties and working conditions on deformation and stress/strain fields created inside the tire. For the simulation, the tire structure is assumed to be composed of tread, carcass ply, and bead. The mechanical behavior of rubber as main component of tire is described by Mooney-Rivlin material model. The comparison of the obtained results and laboratory tests demonstrates the validity and high accuracy of analysis.展开更多

Nowadays Fashion Films are reinforcing the power of fashion images, building up new brand experiences for net-consumers： they are painting new worlds for fashion brands thanks to the old cinematographic language mixed to recent Internet logics. Starting from this observation, our main question was： Can we talk about a new fashion net-aesthetics for these new fashion tales？ Using a semiotics approach, this study investigates how Fashion, Cinema and the Net come together, producing new aesthetics, with new languages and new imaginary in fashion. The result can be really visionary.展开更多

Current estimates indicate over 750 million users of Facebook alone. However, Internet addiction is an increasing problem amongst today＇s youth and as yet, is understudied in the United States. This study looked at the relationship between this new social-networking tool and the increasing phenomenon of internet addiction symptoms using both a US college sample （age 19years） and a US high-school sample （age 14years）. Findings indicate that SNS （Social Networking Site） activity maybe more predictive of addictive behaviors than general internet use and that higher percents of symptomology occur in those users reporting SNS activity as their primary internet activity.展开更多
