This paper analyzes previous work on publish/subscribe in mobile ad-hoc networks with respect to collaboration methods among distributed event brokers. Our experiments suggest that approaches based on event delivery trees are suitable for a scenario where people are served by various personalized services in public spaces. However, these approaches based on independent periodic beaconing may fail...
In this paper, transmission characteristics due to multipath dispersion of indoor optical wireless communication has been analyzed through the simulations and the experiments. Results of simulation using channel modeling have shown that one-reflected response h1 is 63.6 % of the total power and the difference of the magnitude response of DC and 500 MHz is 7 dB. To assess the system performance, eye...
Platinized CaTiO 3 powder (band gap 3.5eV) had a high photocatalytic activity of decomposing water into H 2 and O 2 under the irradiation of UV light, especially with photon energies above 3.8eV. The existence of this photocatalytic activity is further supported on electrochemical grounds in that the photoinduced current spectrum measured between a CaTiO 3 single crystal...
