Nowadays, modern mobile devices have become real personal computers that increase the ability of building/extending existing applications by combining several technologies such as camera, GPS, 3D graphics and permanent Internet connection. The resulting integration of such technologies allows to run complex applications, such as augmented reality and Social Networks. The goal of the present research is to support mobile users' daily activities, by developing advanced solutions which take into account principles of human-computer interaction and usability. In this paper we propose to exploit the potential of the augmented reality and the ability to "communicate" of social networks to create a mobile social network, where each community user may exploit advanced location based services, such as navigation through a two dimensional map, exploration of an area through a camera mode, and identification of points of interest embedded in an augmented reality environment.
Three dimensional scene synthesis and analysis has drawn considerable attention in manufacturing industries due to its multifaceted applications ranging from real time recognition, verification, vehicle guidance etc. ...

For adequate operations of those precision instruments like hard disc and digital video disc drives, the effects of rotating vibrations must be carefully considered in the design stage. In this paper, an axial-winding single-phase brush less DC motor is adopted to form the single-phase spindle motor for its lower cost and better capability of vibration reduction. With proper structure refinement, it is verified that the undesired vibrations and cogging torques of this motor design can be much reduced, and large axial force can be generated to adjust the operational axial displacement. Hence a refined single-phase spindle motor structure that can provide stable operations for related drive applications is thus provided.
