A novel multi-scale operator for unorganized 3D point clouds is introduced. The Difference of Normals (DoN) provides a computationally efficient, multi-scale approach to processing large unorganized 3D point clouds. The application of DoN in the multi-scale filtering of two different real-world outdoor urban LIDAR scene datasets is quantitatively and qualitatively demonstrated. In both datasets the DoN operator is shown to segment large 3D point clouds into scale-salient clusters, such as cars, people, and lamp posts towards applications in semi-automatic annotation, and as a pre-processing step in automatic object recognition. The application of the operator to segmentation is evaluated on a large public dataset of outdoor LIDAR scenes with ground truth annotations.

In a Smart Grid communication network at the power distribution level, several technologies have been suggested to meet communication needs. In this work these technologies are compared with an explanation of why wireless communication technologies may be most suitable. A wireless mesh network architecture is proposed to meet communication requirements of the power distribution system. Subsequently, a performance evaluation exploring connectivity and end-to-end delay when routing packets in this mesh architecture is done for the power grid topology. Optimizations are proposed to enhance overall communication performance, with specific recommendations made on node density, antenna transmission power levels, andapplication data rate.

After the economic crisis in 2009, the real estate market has gone through a temporary prosperity, but now it is undergoing the country's another round of macro control. In order to comply with the national's implementation of "one-room, one- price" policy and make second-hand housing market standardized. A comprehensive analysis of our country's real estate prices and the latest development trends is made in this paper, besides;the analysis is based on the real estate evaluation theory. This paper presents a novel real estate estimation method based on spatial decision support system, theoretical analysis and the application of computer technology, this approach is an integration of decision support systems (DSS) and Geographic Information systems (GIS). Meanwhile, it can make our country's real estate evaluation more regular and scientifically.
