To investigate the erosion of graphite and B4C under high particle flux loading, such as in a fusion reactor, two types of specimen, i.e. isotropic graphite PD330S and conversion B4C, were irradiated by a high flux neutral beam generator. The erosion

This paper presents a relay method with a P-MP (point to multipoint) structure by extending the IEEE 802.16-2004 standard in order to expand the coverage area (2004). In the proposed relay method, a RS (relay station) sends a polling message for the
