This paper proposes an improved K-means algorithm for the clustering analysis of dangerous goods transportation from logistics platform. The improved algorithm uses the distance dissimilarity between clusters to gain cluster coefficient, K, in order to avoid poor clustering effectiveness caused by the subjective K-value settings. And the improved algorithm also uses the spatial data feature extraction...
In recent years, as the fast growth of the mobile users, network coverage area becomes larger, then so does the number of base stations (BSs). Therefore, how to predict network coverage scientifically and effectively, how to project base station construction and how to make the best effect of the base station network coverage are to be solved urgently. However, the selection of the base station location...
The coordinate acquisition of curve seam in robotic laser welding is becoming very important due to its strict demands for high accuracy and high speed. The precision of the coordinates of curve seam is crucial to guarantee the welding quality. This paper presents an approach by using Ghosal's algorithm based on orthogonal Zernike moments for acquiring the coordinates of welding seam which is sine...
