The widespread use of multimedia networking applications has created the need for QoS support in the WLAN systems. The coverage area of WLAN systems is limited, so multi-hop WLAN system is considered to be one of the solutions. However , in home or office environments, due to the multipath propagation effect, the performance of multi-hop WLAN system is(More)
SUMMARY Millimeter-wave (mmw) frequency bands, especially 60 GHz unlicensed band, are considered as a promising solution for gigabit short range wireless communication systems. IEEE standard 802.11ad, also known as WiGig, is standardized for the usage of the 60 GHz unlicensed band for wireless local area networks (WLANs). By using this mmw WLAN, multi-Gbps(More)
BACKGROUND Treatment failure at the primary site after chemoradiotherapy is a major problem in achieving a complete response. Photodynamic therapy (PDT) with porfimer sodium (Photofrin®) has some problems such as the requirement for shielding from light for several weeks and a high incidence of skin phototoxicity. PDT with talaporfin sodium (Laserphyrin) is(More)
