The grain boundary region and pore play an essential role in nanostructured materials. In the present study, nanoporous (np-) Au prepared by dealloying (DA np-Au) is studied by means of the anelasticity measurement referring to the nanocrystalline (n-) Au prepared by the gas-deposition method (GD n-Au). In GD n-Au >0.99 (the subscript, >0.99, denotes the relative density of the specimen...
We propose a subchannel allocation by considering multiuser diversity to reduce self interference (SI) which arises due to the destrunction of orthogonality of spreading codes in orthogonal frequency division mutiple access - code division multiplexing (OFDMA-CDM) system. The conventional OFDMA-CDM does not effectively reduce SI, since it does not consider multiuser diversity. The proposed scheme...
We developed an automatic tracking system camera for TV program production that is capable of making stable shots by detecting the performers' facial positions. This system can make tracking shots as specified by the user, by using a subject detection module in which input images are simultaneously processed by several image-processing algorithms installed in PCs on a local network. The robot camera...
