Assuming that the Raman gain profile of silica fiber is a triangular function, we derive analytic solutions of N-channel steady-state forward SRS coupling wave
We have investigated the fast power transient effect of the cascaded erbium-doped fiber amplifiers (EDFA) in wavelength routed optical networks. The bit error r
The application of microbial technology to mineral processing has been reviewed with respect to the bioleaching of metals from minerals, the influence of biotre
The strengthening and toughening effect of yttrium on an advanced Al2O3/TiCN ceramic tool material was studied by means of SEM, TEM and energy spectrum analysis
π/4-DQPSK modem has been chosen as the modem scheme in many mobile communication systems. A new signal processing technique of π/4-DQPSK modem based on softwa
The SnO2-x with different oxygen vacancy concentrations was modified by adding Sm. The modified SnO2-x was investigated by means of X-ray diffraction, X-ray pho
In previous researches on a model-based diagnostic system, the components are assumed mutually independent. Howerver , the assumption is not always the case bec
Based on a method of finite element model and combined with matrix theory, a method for solving differential equation with variable coefficients is proposed. Wi
Chaotic communication is a rather new and active field of research. Although it is expected to have promising advantages,some investigators provide evidences th
