Research on coverage of wireless sensor networks are mostly aiming at isomorphic nodes, however, which gives little attention on heterogeneous nodes. There haven't been effective solutions up to now. Adopting Probability Coverage Model is more efficient relatively, which can obtain more accurate data. By means of computing the coverage probability of each node, we infer the coverage probability of...
This article used statistical data of recent two years. Under the condition that RMB satisfies Markov property, we used Markov chain to compute the frequency matrix and transition probability matrix and moreover, we predicted the future trend of exchange rate. We also simulated the original data using AR model, and added residual factor that is from analysis of Markov Chain. Finally, we got a model...
In this paper, a Hough transform (HT) based track initiation method is proposed to detect targets in 3L (low signal-to-clutter-ratio, low signal-to-noise-ratio, and low detection probability) environment using a new and effective accumulation method. In the new accumulation method, the contributions of each cell's votes are determined by the neighbors of the resolving cell, instead of just the cell...
