Assim, e pela leitura dos gráficos das situações anticiclónicas mais frequentes, constata-se que os padrões de distribuição anual, nos dois períodos em estudo,

To our knowledge, this is the first integrated approach that implements both a weighting scheme and semantic similarity to select the correct annotation. This approach has proven to

The control channel must also be free from primary user activity and as well as from rendezvous between other pairs of radios in the multi-user (multiple secondary users)

and covering the bandwidth B (in Hertz). For a given geographic area, the FCC would establish an interference temperature limit. This value would be the maximum threshold of

By introducing the trust scheme into the fuzzy logic scheme to represent the reliability of the nodes, a cooperative spectrum sensing scheme based on trust and fuzzy logic for

In this paper we propose a novel scheme, which can select decoding parameters (based on the special attribute of different kinds of streaming media program) automatically
