For nonlinear dynamic analysis of the experiment data, one often uses SVD decomposition to reconstruct embedding dimension of attractor because of its simpleness. However, it is hardly for singular value decomposition (SVD) decomposition to get good results in the attractor reconstruction of the experiment data. For this, symplectic geometry method is proposed to estimate embedding dimension of reconstruction attractor in this paper. We illustrate the feasibility of this method and give the embedding dimension of the action surface EMG signal.

The security architecture and mechanism of 3rd generation mobile communication are discussed in this paper. Five UMTS security features are given. Then the security architecture is introduced. We analyzed the basic network access security mechanism and give the flow description regarding to the signalling procedure. For the integrity protection and data confidentiality, the corresponding algorithm is also discussed.
