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 ...
Shortest path problem is among the most interesting problems in the field of graph and network theory. There are many efficient matrix based algorithms for detecting of shortest path and distance between all pairs of this problem in literature. In this paper, a new exact algorithm, named Cascade Rectangle Algorithm, is presented by using main structure of previous exact algorithms and developin...
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...
abstract nowadays, the science of decision making has been paid to more attention due to the complexity of the problems of suppliers selection. as known, one of the efficient tools in economic and human resources development is the extension of communication networks in developing countries. so, the proper selection of suppliers of tc equipments is of concern very much. in this study, a ...
abstract this study tried to investigate whether there was any significant relationship between technical translation quality of the senior english translation students and their levels of verbal-linguistic, visual-spatial and interpersonal intelligences. in order to investigate the research questions, the researcher selected a hundred senior english translation students from three universitie...
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...
