In our recent works, we developed a probabilistic framework for structural analysis in undirected networks. The key idea of that framework is to sample a network by a symmetric bivariate distribution and then use that bivariate distribution to formerly define various notions, including centrality, relative centrality, community, and modularity. The main objective of this paper is to extend the probabilistic...
In this paper, we propose a novel visual analysis method TrajRank to study the travel behaviour of vehicles along one route. We focus on the spatial-temporal distribution of travel time, i.e., the time spent on each road segment and the travel time variation in rush/non-rush hours. TrajRank first allows users to interactively select a route, and segment it into several road segments. Then trajectories...
A circular survey using GPR is employed for tree roots detection in field measurement. A new 3D imaging algorithm is also proposed for implementing the 3D reconstruction of the subsurface targets in cylindrical coordinate system. The proposed algorithm can avoid the spatial interpolation of the acquired data between coordinate systems and employs the wave equation extrapolation technique to implement...
Holographic subsurface imaging radar (HSIR) has high plane imaging resolution, and has the potential in the application of human body inspection. This paper studies mainly on the feasibility of using HSIR in the medical diagnosis. A series of experiments have been carried out to image the different parts of human body, including palm, forearm, leg, knee, chest, back, and belly. The imaging results...
Choosing the non-ST listed companies as the objects, the research aims at using the Fisher Discriminant Analysis method to estimate the real value of the listed company via subdividing the outstanding achievements of the non-ST listed companies. The misjudgment rate of the model is low, which shows that the Fisher Discriminant Analysis could predict precisely, so it could be used as an efficient investment...
