The integer factoring problem is one of the oldest and important problems and it is considered as hard, i.e., the problem cannot be solved in polynomial time for the worst case, because the security of RSA is heavily dependent on the difficulties of integer factoring. As is well known, hardware technology is progressing rapidly from year to year and it seems that the time is now ripe to factor ...

Rotation Transformation is the backbone of visualization of 3D objects. Rotation transformations allow viewing objects from different angles. Rotations about the principal axes are straightforward whereas the rotation about an arbitrary axis is complex. In mobile environment, rotations is computed continuously as the objects move and is thus a costly operation. We give intuitive, constructive, ...
