Collaborative beamforming has been widely used in wireless sensor networks to improve the directivity of signals in long-distance transmission. The performance of collaborative beamforming has been well analyzed for the case without phase offset in the literature. However, there always exists the phase ambiguity caused by carrier phase jitter between the transmitter and receiver nodes in a practical...
The novel photocatalyst, La2O3-NiO, was prepared by sol-gel with nickel nitrate hexahydrate and lanthanum salt, characterized by means of XRD and SEM. Its photocatalytic activities were evaluated by degradation of Direct Bordeaux (DB) solution as a simulated dye wastewater under daylight irradiation. The results show that Pure and La-doped NiO are a cubic perovskite structure with space group Fm-3m...
An approximation controller is developed to obtain an optimal control for nonlinear networked control systems (NCS) with time delay. In the approach only the non-linear compensating term, solution of a sequence of adjoint vector differential equations, is required iteration. By taking the finite iteration of non-linear compensating term of optimal solution sequence, a suboptimal control law for NCS...
