This paper studies the transient and steady performance constraints on flexible joint manipulator system with exogenous disturbance, proposes a fixed-time prescribe tracking control method based singular perturbation model. For fast subsystem, subcontroller superior is proposed that guarantees suppression of vibration in fixed-time. The remaining slow subsystem can be linked rigid methods to ac...

The per-sample zero-dispersion channel model of the optical fiber is considered. It shown that capacity uniquely achieved by an input probability distribution has continuous uniform phase and discrete amplitude takes on finitely many values. This result holds when subject to general cost constraints, include a peak constraint joint average constraint.

Current research on qualitative spatial representation and reasoning usually focuses on one single aspect of space. However, in real world applications, several aspects are often involved together. This paper extends the well-known RCC8 constraint language to deal with both topological and directional information, and then investigates the interaction between the two kinds of information. Given...

In this paper, a joint spectrum sensing and accessing optimization framework for a multiuser cognitive network is proposed to significantly improve spectrum efficiency. For such a cognitive network, there are two important and limited resources that should be distributed in a comprehensive manner, namely feedback bits and time duration. First, regarding the feedback bits, there are two componen...
