This paper examines the spatial spillover effects of public transportation infrastructure on regional economy in Northeast China, “rust belt” region China. The dataset consists socioeconomic data from 47 cities area during period year 2005 through 2015. Accessibility is used as an explanatory variable to reflect influence economic development. In order avoid endogenous, queen contiguity matrix ...

The walk distances in graphs are defined as the result of appropriate transformations of the ∑∞ k=0(tA) k proximity measures, where A is the weighted adjacency matrix of a connected weighted graph and t is a sufficiently small positive parameter. The walk distances are graph-geodetic, moreover, they converge to the shortest path distance and to the so-called long walk distance as the parameter ...

making an informed decision with regards to a suitable business location or site selection for organizations is becoming challenging for business decision makers globally; and even more challenging in business environment that are saddled with uncertainties. the continues raise of multiple criteria variation of site preferences has also necessitated the application of advanced decision making t...

This paper proposes a spectral clustering method using k-means and weighted Mahalanobis distance (Referred to as MDLSC) enhance the degree of correlation between data points improve accuracy Laplacian matrix eigenvectors. First, we used coefficient weight calculate any two constructed set; then, based on matrix, K-nearest neighborhood (KNN) algorithm construct similarity matrix. Secondly, regul...

1. introduction natural hazards have existed in all periods of human life, but nowadays due to the exponential growth of human and population density in all aspects of life, especially in high risk areas, human has been faced with major disasters such as the asia tsunami, hurricane katrina and the earthquake in sichuan of china with significant casualties even in developed countries. these haza...
