In this paper, we study the thermal effects on the asymptotic behavior of a simple planar network of elasticities with variable coefficients. Assume that the network consists of three edges. the exterior vertices of the network are clamped. The conservative laws (self-adjoint conditions) are fulfilled at the common vertex. We prove that the network is well-posedness based on the semigroup setting...
This paper deals with the identification of Wiener systems with hard nonlinearities. Using the switching function, a special form of nonlinearity representation is used in the Wiener system description. Two recursive identification algorithms are proposed, one is the recursive stochastic gradient identification algorithm and the other is the adaptive forgetting through multiple models identification...
In this note, we firstly recall the main results in [1] and their brief proofs. As applications of the results, we study the control problem of the general networks of strings. Some new examples of networks of strings with circuits are given.
In this paper we consider the dynamical stability of a tree-shape networks of Timoshenko beams with time-delay terms in the boundary controls. The time-delay feedback controllers at the exterior vertices are designed to derive the beams back to its equilibrium position. We first get the wellposedness of the closed loop system. Under certain conditions, we show that this system is asymptotically stable...
Due to fixed window area-based stereo algorithms having given rise to relatively large matching errors around depth discontinuities, a adaptive window for stereo matching algorithm using integral image was proposed in this paper. A new similarity function and Four-direction line mask were employed in initial parallax gain aspect, not only to reduce noise effects but also to improve matching accuracy...
