Resource allocation pattern in infrastructure networks (2008)
Kim, Dong-Hee, Motter, Adilson E.
Most infrastructure networks evolve and operate in a decentralized fashion, which may adversely impact the allocation of resources across the system. Here we investigate this question by focusing on...
Codebook Based Space Division Multiple Access with Partial Side Information (2008)
LEE, Myoung-Won, MUN, Cheol, KIM, Dong-Hee, YOOK, Jong-Gwan
In this letter, a codebook based multiuser MIMO precoding scheme is proposed for a space-division multiple access (SDMA) system with limited feedback. Focusing on the case of SDMA systems with two...
Ensemble averageability in network spectra (2007)
Kim, Dong-Hee, Motter, Adilson E.
The extreme eigenvalues of connectivity matrices govern the influence of the network structure on a number of network dynamical processes. A fundamental open question is whether the eigenvalues of...
Kim, Dong-Hee, Lin, Yu-Cheng, Rieger, Heiko
The discrete time path integral Monte Carlo (PIMC) with a one-particle density matrix approximation is applied to study the quantum phase transition in the coupled double-well chain. To improve the...
Inhomogeneous substructures hidden in random networks (2006)
We study the structure of the load-based spanning tree (LST) that carries the maximum weight of the Erdos-Renyi (ER) random network. The weight of an edge is given by the edge-betweenness centrality,...
Systematic analysis of group identification in stock markets (2005)
We propose improved methods to identify stock groups using the correlation matrix of stock price changes. By filtering out the marketwide effect and the random noise, we construct the correlation...
