The passenger flow data of urban rail transit (URT) network has the characteristics of large scale, fast-update, multi-mode, difficult to identify and great value, the same as Big Data. It is meaningful and effective to use big data visualization in passenger flow analysis. In this paper, with high visualization frameworks, the massive data of passenger flow in Shanghai Metro network is highly graphical...
In the present work, the model of the performance testing room for refrigerating container was developed. This model is used to investigate the velocity field and temperature field under two different air supply schemes which are upper supply-upper return and horizontal supply in the testing room. The results show that the velocity field and temperature filed of the horizontal supply scheme are more...
In this paper we deeply research Lagrange interpolation on the unit sphere. First we study the Lagrange interpolation problem along a set of latitudes on the sphere and give three kinds of properly posed sets of nodes along it. Then we get a class of properly posed set of nodes for Lagrange interpolation on the unit sphere by superposition interpolation process. The result in this paper is an extension...
In this paper, we present an automatic terminology extraction approach for Chinese multi-word terms. In this term extraction system, besides five linguistic rules acquired from an available term list by some machine learning methods, two statistical strategies are involved: a termhood measure based on the term distribution variation, and a unithood measure adopting the left and right entropy method...
