In the mobile environment, the dropped calls can be resulted from shadowing and rapid signal loss. As the cells shrink to accommodate an increasingly large dema
Recent traffic measurements in corporate LANs, Variable-Bit-Rate (VBR) video sources, ISDN control channels, and other communication systems, have indicated tra
Stopping powers for Ge ions (3.5MeV~8.0MeV) in Al foil were measured with RBS (Rutherford backscattering) technique and determined with a new method. Our results
