This paper deals with the synchronization of networked harmonic oscillators under nonlinear protocols. Some convergence analysis for such networked harmonic oscillators, both without and with a leader, are provided by means of algebraic graph theory, matrix theory and Lyapunov stability theory on dynamical systems. We show that the networked harmonic oscillators can achieve synchronization under nonlinear...
To deal with attribute reduction in incomplete information systems, this paper proposed a direct method of attribute relative reduction based on rough set theory. This reduction algorithm gives the concept of tolerance relationship similar matrix via extending equivalence relationship of rough set theory, which is called tolerance relationship. It introduces the generalized decision function to solve...
Profile is an indication of matrices storage efficiency. Usually profile reducing techniques are applied to sparse symmetric matrices. This paper adapts the most commonly used reverse Cuthill-McKee algorithm for asymmetric matrices, and introduces a new algorithm for reducing the profile of a sparse asymmetric 0-1 matrix. Finally, the algorithms reduction efficiency are illustrated and compared.
In conventional TV, users can get only a single view of a real 3D world. The view is determined not by a user but by the camera position during acquisition. Free viewpoint television (FTV) is a new concept which aims at giving viewers the flexibility to select a novel viewpoint by employing multiple video streams as the input. Current proposed solutions for FTV include those based on ray-space sampling...
