Aiming at the wireless sensor network (WSN) positioning of the centroid localization algorithm with the problem of inaccurate positioning, this paper proposes an improved weighted centroid localization algorithm based on RSSI. This algorithm regard the distance between the unknown node and the reference of anchor nodes as the weight in centroid localization algorithm, make full use of the unknown...
In accelerated and controlled cooling (ACC) processes, the relationship between the plate velocity and the final temperature of plate point is complicated and implicitly expressed, with undetermined ending time of the plate cooling. It is difficult to obtain the optimal plate velocity to accurately control the final temperature. A novel control methodology is proposed to improve the accuracy of the...
A novel adaptive, multi-channel, tree-structure wavelets transform is introduced in this paper. Its high efficiency of texture classification, global evaluation and feature extraction is illustrated by the experiment at end of this paper. It can achieve good application results in real application.
Based on the minimize spanning tree and Fiedler vector, a new feature matching algorithm is proposed in this paper. Firstly, a weighted complete graph is constructed with the feature points of each image respectively, then search the minimal spanning tree in each complete graph. Secondly, perform spectral decomposition on the Gaussian-weighted Laplace matrix of the minimize spanning tree respectively,...
