To meet the increasing capacity and mobility as well as decrease the costs in next-generation optical access networks, RoF technology is a promising technique in the emerging optical and wireless convergence network, mm-wave generation is a key technique to realize the convergence network. In this paper, existing optical mm-wave generation technologies are introduced, including direct modulation, optical heterodyning and external modulation. Associated with Shanghai University, a scheme based on Optical Frequency Multiplication employing a dual drive Mach-Zehnder Modulator (DD-MZM) is presented. The novel efficient technique does not require expensive high-frequency electrical equipment. Moreover, no optical filtering is used, which significantly reduces the cost.

A modified method of conventional D-S evidence combination rule was presented. The consensus index of evidence based on distance measures of evidence was introduced into modifying the BPAs of hypotheses with the evidence sufficiency and evidence importance. By using the D-S combination and new decision rules, the different sets of BPAs for each hypothesis were calculated. A numerical example of the fault diagnosis is used to demonstrate the validity of the method by comparison with other methods.
Identification of protein-protein interaction is crucial for nearly all biological process. In this paper, we introduce a new transformation of protein sequence based on sequence order information. We use 5594 interac...
