This paper tends to build an econometric model in the perspective of the endogenous growth and new economy geography, and examines how the spill-over effect and scale economies of logistics agglomeration affected the development of Chinese logistics industry based on the panel data of 31 provinces between 2003 and 2012. The results show that the spill-over effect of logistics agglomeration has made...
In image detection, it is often necessary to detect the sizes of foreign bodies in binary images. A new method to detect particle sizes of objects is proposed in this paper based on binary image analysis. A difference sum template is first used to extract edge of an object, a half-8-connected domain algorithm is then employed to obtain the coordinates set that corresponds to each object, and finally...
There is a model for traffic circles. During the process, we have done a careful research to the former traffic circles which have already been put into practice. Some inspiration drives us to find a distinctive solution program to control the traffic flow. We name it DSC (Different Speed in the Circle). It regulates some new rules and can be implemented conveniently. The design divides the circle...
Center of gravity is an important index to describe spatial distribution of geographical objects, it can exactly reflect spatial distribution and evolution characteristics of geographical elements. Using gravity model, this paper makes a detailed analysis on variation track about urban land price and land spatial expansion of Shijiazhuang from aspects of location, moving direction, distance of land...
