Slope movements have caused severe damages of civil infrastructures and numerous human fatalities. Continuous monitoring of slope movements and the collection of vital landslide information are benefi...
Permutation Complexity and Coupling Measures in Hidden Markov Models
Permutation Complexity Coupling Measures Hidden Markov Models Chaotic Dynamics
2012/4/26
In [Haruna, T. and Nakajima, K., 2011. Physica D 240, 1370-1377], the authors introduced the duality between values (words) and orderings (permutations) as a basis to discuss the relationship between ...
Long-term fluctuations in globally coupled phase oscillators with general coupling: Finite size effects
Long-term fluctuations globally coupled phase oscillators general coupling Finite size effects Chaotic Dynamics

We investigate the diffusion coefficient of the time integral of the Kuramoto order parameter in globally coupled nonidentical phase oscillators. This coefficient represents the deviation of the time ...
Threshold Improvement of Low-Density Lattice Codes via Spatial Coupling
Low-Density Lattice Codes Spatial Coupling Information Theory
2011/9/20
Abstract: Spatially-coupled low-density lattice codes (LDLC) are constructed using protographs. Using Monte Carlo density evolution using single-Gaussian messages, we observe that the threshold of the...
Cluster Synchrony in Systems of Coupled Phase Oscillators with Higher-Order Coupling
Cluster Synchrony Coupled Phase Oscillators Higher-Order Coupling
2011/9/29
Abstract: We study the phenomenon of cluster synchrony that occurs in ensembles of coupled phase oscillators when higher-order modes dominate the coupling between oscillators. For the first time, we d...
Let X_i, Y_j, i, j = 2…, n, be independent nonnegative r.v.'s with X_i～ F_i(t) = 1-exp(-R_i(t)) and Y_j～ G_j(t) = 1- exp(-R(t)), j=1,…, n. Two kinds of models are considered, and the monotone coupling...
