The paper concerns on the free vibrations of circular plate with arbitrary number of the elastic supports and the elastically mounted masses at arbitrary positions by using the integral equation method. A set of complete systems of orthogonal functions, which is constructed by Bessel functions of the first kind, is used to construct the Green's function of circular plates firstly. Then the eigenvalue...
Sparse multi-path channels (MPC) are often encountered in several wireless communications. Exploiting the sparse property of MPC, several estimation methods have been proposed in recent years. Unlike the previous methods based on either dense MPC or sparse MPC models, we propose a novel MPC estimation method based on a generalized hybrid MPC model. The existed least squares (LS) and sparse component...
A software system can be modeled by a transition system. In the existing approaches for software modeling, such as FSM, EFSM, and TM etc., states often have specific physics semantics which often represent variables, processes, or modules, etc. In this paper, a data mining approach is introduced into software modeling to do state definition in a different way. The approach is used to extract interesting...
