This paper studies the distributed localization problem of large scale wireless sensor networks with MDS-MAP method. Under the MDS-MAP framework, the original merging condition is firstly analyzed and generalized to several relaxed conditions, then an improved merging strategy is designed by introducing a novel MDS approach presented in [1]. Due to the improved merging strategy can perform well for...
This paper is concerned with the non-fragile H∞ filtering problem for a class of time-varying systems with randomly occurring gain variations (ROGVs), channel fading and probabilistic constraints. A set of mutually independent random variables with known probability distributions are introduced to describe the random parameter noises and randomly occurring parameter fluctuations during the filter...
This paper proposes a watermarking algorithm for 3D meshes based on local roughness analysis. The proposed method is a robust and partition-based watermarking method. It is composed of two stages: watermark embedding and extraction. During the watermark embedding stage, the input mesh is decomposed into groups corresponding to different values of roughness, which is measured by the Laplacian of Gaussian...
The problem of adaptive tracking control for a class of switched systems with uncertainties and time-delay is studied. The adaptive tracking controller which is not related with the unknown bounds of the uncertainties and disturbance. By introducing Linear matrix inequality and choosing a Lyapunov function, the system with uncertainties and time-delay may track asymptotically model reference system.
