The combination of a 3He proportional counter and a 4He proportional counter sharing the same parameters was employed as the low background thermal neutron detector. The wall material is oxygen-free copper for low surface a emit rate. Other characters including wall effect and energy resolution were also optimized for low background performance. A portable readout electronics system has been developed...
In multi-level HMIPv6 (M-HMIPv6) networks the MN has to select a proper MAP using MAP selection schemes when migrating to the visited ARs. Currently, distance-based MAP Selection (DMS), Mobility-based MAP Selection (MMS) and Adaptive MAP Selection (AMS) schemes have been proposed, and AMS outperforms the other ones in several aspects. However, none of these schemes consider the handover Quality-of-Service...
Since the initial prediction and experimental demonstration of magnetization reversal by spin transfer torque (STT), there has been continuous progress toward the development of nonvolatile magnetic random access memory based on STT switching (STT-RAM) in nanoscale magnetic tunnel junctions (MTJs). In the most common STT-RAM configuration shown in Fig. 1(a), the magnetic moments of the free layer...
