UNDERSTANDING URBAN TRAFFIC FLOW CHARACTERISTICS FROM THE NETWORK CENTRALITY PERSPECTIVE AT DIFFERENT GRANULARITIES
taxi trajectory granularity network centrality
2016/7/8
In this study, we analyze urban traffic flow using taxi trajectory data to understand the characteristics of traffic flow from the network centrality perspective at point (intersection), line (road), ...
NETWORK CENTRALITY AND INSTITUTIONAL DESIGN: EVIDENCE FROM A LAB EXPERIMENT IN THE FIELD
Social networks Institutional design Informal contracting
2015/7/15
While social closeness mitigates contractual incompleteness, we examine how communities
can enlist third parties to improve cooperation between socially distant pairs. Network-central members
may be...
利用Betweenness Centrality计算网络流量矩阵的新算法
中间度核心性 复杂网络 贪婪算法 流量矩阵
2012/4/19
引入Betweenness Centrality中间度核心性作为候选快照的选择指标，特别是以其中的GBC群组中间度核心性作为考量多链路权重改变时各链路的选取问题，实验结果表明，BC的引入加快了秩的提高，而GBC可以衡量群组大小不同时会对原系统产生影响的程度；同时指出将GBC作为唯一指标在实际操作层面存在问题，需要综合考虑其他因素。最后提出将来结合序列RBC与GBC进行计算的研究方向。
Evolution of the differential transverse momentum correlation function with centrality in Au+Au collisions at $\sqrt{s_{NN}} = 200$ GeV
transverse momentum correlation Au+Au collisions Evolution
2011/7/20
We present first measurements of the evolution of the differential transverse momentum correlation function, {\it C}, with collision centrality in Au+Au interactions at $\sqrt{s_{NN}} = 200$ GeV. {\it...
Bounded Budget Betweenness Centrality Game for Strategic Network Formations
Bounded Budget Betweenness Centrality Game Strategic Network Formations
2012/12/3
In this paper, we introduce the bounded budget betweenness centrality game, a strategic network formation game in which nodes build connections subject to a budget constraint in order to maximize thei...
