Multi-modal information fusion plays an important role in many robotic applications, such as target grasping, manipulation and fine operation. Traditional fusion strategies, e.g. Bayesian fusion, directly adopt each uni-modal likelihood without giving enough attention to the fact that all these likelihoods are often vulnerable to sample data and modality-specific identification algorithm, which could...
We present a relative location estimation algorithm based on the coordinates inner product matrix-based maximum likelihood (CML) for determining the relative locations of sensor nodes in wireless sensor networks. We use the geodesic distance between each node to obtain the coordinates inner product matrix, then derive the maximum-likelihood estimator for coordinates inner product matrix to estimate...
Due to the impacts of the loop bandwidth, the high dynamic environment could cause the carrier tracking loop of the GPS receiver loss of lock, and the pseudo-code tracking loop errors increased. According to the characters of the high dynamic environment, a GPS IF digital signal source is firstly designed here, then an improved carrier tracking loop based on the UKF is proposed, which works steady...
An improved localization algorithm W-Ecolocation in wireless sensor network is proposed. When there is a high erroneous constraints rate, the Ecolocation algorithm which only considers the locations with maximum computing number of matched constraints cannot obtain the optimal location estimate. The W-Ecolocation makes use of more locations with great computing number of matched constraints and takes...
This paper proposes the design concept of sand-dust storm warning system based on data collection techniques, grey relation analysis and support vector machine classification forecasting model. We have successfully designed sand-dust storm warning system by the three sub-modules that they are the analysis, classification and forecasting system, and the article details grey relation analysis, support...
An integral part of China's economic reforms is the privatization of state-owned enterprises (SOEs) and listing the profitable units of the SOEs on the stock market. The two stock exchanges in Shanghai and Shenzhen were opened nearly twenty years ago. The Shenzhen stock exchange market is young and energetic. Moreover, it practices a T+1 settlement rule instead of real time trade as in Hong Kong or...
