In this paper, a computationally efficient method that combines the subspace and principal singular vectors utilization for modal analysis (PUMA) is proposed for 3-D frequency estimation of multiple damped sinusoids. The perspective idea is the construction of 2-D sliced matrices from 3-D sinusoids, and then the 2-D sliced matrices are used to construct a set of covariance matrix to obtain the SVD of each covariance matrix. The available PUMA method is employed to estimate the frequencies and the damped factors in each dimension. Moreover, we can use existing matching algorithms to pair the 3-D frequency parameters. Only the original scale of sampled data is fully utilized, so the proposed method is more computationally attractive than the two existing methods.

In this paper, robust control for nonlinear uncertain systems with input nonlinearity is considered by using operator based robust right coprime factorization approach. In details, an operator based control design structure is proposed for nonlinear uncertain system with input nonlinearity. Based on the proposed design scheme, the designed system is robustly stable. Moreover, the desired output tracking performance can be realized simultaneously. Finally, a simulation example on a nonlinear plant preceded by unknown backlash is given to show the design procedure of the proposed method.

Achieving three-dimensional entanglement between two spatially separated atoms by using the quantum Zeno effect

Physical Review A 2013年第6期87卷 062316-062316页

Based on the quantum Zeno effect [B. Misra and E. C. G. Sudarshan, J. Math. Phys. 18, 756 (1977)], we propose a scheme to achieve three-dimensional (3D) entanglement between two distant five-level atoms. In our scheme, the two atoms are trapped individually in two spatially-separated double-mode cavities connected by an optical fiber. It is found that the effective quantum Zeno dynamics of the composite cavity-fiber-cavity coupled system gives rise to the deterministic creation of the 3D entangled state with high fidelity. Moreover, only one step operation is required to complete the generation of the 3D entangled state. The numerical simulations clearly show that the proposed scheme is robust against the deviation of the system parameters and insensitive to various decoherence factors, including atomic spontaneous emissions, cavity decays and fiber photon leakages. We justify our scheme by considering the experimental feasibility within the currently available technology.

Generation of long-time maximum entanglement between two dipole emitters via a hybrid photonic-plasmonic resonator

We explore the entanglement generation between two dipole emitters via a hybrid photonic-plasmonic resonant structure which consists of two metal nanoparticles (MNPs) and a high-Q whispering-gallery-mode (WGM) microcavity. Because the coupling strength between the dipole emitter and the cavity can be substantially enhanced with the help of MNPs and maintained by the WGM cavity, the maximum entanglement plateau between two dipole emitters can be deterministically created even in the presence of the spontaneous emission of the dipole emitters and the decay induced by the microcavity and MNPs. The width of the plateau depends on the coupling strengths (or the radii of the MNPs) and the initial state, but is insensitive to the dipole-cavity detuning. These results are useful in real experiments.

In this paper, operator-based robust control for Multi-Input Multi-Output (MIMO) aluminium plate thermal process is considered. In details, a 3-input 3-output aluminium plate temperature control process is demonstrated and the model of the process is given. For considering the robust control of MIMO non-linear system, one class of operator-based MIMO system is described and the control system design is given. Based on the proposed design scheme, the system is robustly stable and the desired output tracking performance can be realised. Finally, the theoretical analysis is applied onto the 3-input 3-output aluminium plate temperature control process and the effectiveness of the theoretical analysis is demonstrated by the simulation and experimental results.

With the ubiquity of information networks and their broad applications, the issue of similarity computation between entities of an information network arises and draws extensive research interests. In this paper, three kinds of similarity measures link-based of information network are presented according to the conceptual representation of information network respectively. The main advantage of these types of methods resides in their ability to produce systematically better correlation with human judgments compared to the traditional method such as the text-based ones. Moreover, this paper surveys effectives and quality of query of three the kinds of similarity measures. By presenting these methods in the same link-based framework, we hope this paper may shed some light on deciding which methods are more suitable to use in different situations.

A least squares estimation algorithm for the azimuth and elevation angles as well as range of a single near-field source impinging on a uniform circular array is proposed. By exploiting the centro-symmetric array configuration, two correlation functions are devised to obtain their closed-form estimates. It is shown that the proposed method gives comparable estimation performance with that of the conventional MUSIC scheme but the former is much computationally simple. © 2011 IEEE.
