Power distribution network is the bridge between power transmission and power consumers, which is an important part of directly feeling the service quality of the power supply by consumers. Intelligent power distribution network of smart grid is an important means to improve power supply reliability and quality of power supply, and real-time monitoring of the distribution network is an important foundation...
This paper proposed an approximate model for the global power spectral density (PSD) of primary users (PUs). Based on the proposed model, a novel cooperative spectrum sensing algorithm was proposed, and its overall flow was also built to obtain global information in the network of PUs. The global information includes locations, occupied frequency bands and transmit powers of the PUs. Then, an estimator...
Non-convex non-smooth (NCNS) regularization has advantages over convex regularization for restoring images, but it may lead to challenging computation. In this paper, an adaptive non-convex non-smooth (ANCNS) regularization is proposed for image restoration by using the spatial information indicator. Moreover, an efficient numerical algorithm for solving the resulting minimization problem is provided...
Moving target indicator (MTI) analysts in the field are responsible for processing the increasing amounts of live streaming data. Analysts manually access unique data sources through a set of tools, and perform analysis on the available data. Operationally, analysts can only concentrate on small areas of interest and are subject to attentional blindness. Abnormalities in the periphery are often not...
This paper firstly introduces the importance of satellite illumination analysis in aerospace fields and points out that illumination conditions will influence the design of shape of satellite body and the installation of satellite equipments. Then, it discusses two methods for analyzing satellite solar-panel shadow and illumination conditions: ray tracing illumination algorithm and polyhedral mesh...
The sampling storage method which used in the current data stream could not respond data tendency effectively. For the problem, this paper presents a new processing method based on curve fitting. A weighted least-square principle is used to fit the cached stream data and better model description is obtained. Then the fitting results are analyzed by clustering algorithm, which serves as a classifier...
This paper presents a novel information hiding algorithm for AVS (audio video coding standard), taking advantage of the specific features of this self developed Chinese audio video compression standard. AVS adopts Exp-Golomb coding and context based adaptive variable length coding to solve the entropy coding problem, almost all the syntax elements are encoded using Exp-Golomb codes. In the compressed...
