The paper presents a novel hydraulic fracturing model for the characterization and simulation of the complex fracture network in shale gas reservoirs. We go beyond the existing method that uses planar...
Refining network reconstruction based on functional reliability
Directed acyclic graph Discover causes and effects Sequential structural learning
2016/1/25
Given a target variable and observational data, we propose a sequential learning approach for discovering direct cause and effect variables of the target under the causal network frame-work. In the ap...

Sparse graph codes probabilistic channel models Shannon channel capacity network coding
2015/8/20
We consider communication over a noisy network under randomized linear network coding. Possible error mechanism include node- or link- failures, Byzantine behavior of nodes, or an over-estimate of the...
An Inclusion-Exclusion Algorithm for Network Reliability with Minimal Cutsets
Inclusion-Exclusion Formula Network Reliability Minimal Cutset Dynamic Programming
2013/1/30
The inclusion-exclusion formula (IEF) is a fundamental tool for evaluating network reliability with known minimal paths or minimal cuts. However, the formula contains many pairs of terms which cancel....
Differential equation approximations of stochastic network processes: an operator semigroup approach
dynamic network birth-and-death process one-parameter operator semigroup
2011/9/6
Abstract: The rigorous linking of exact stochastic models to mean-field approximations is studied. Starting from the differential equation point of view the stochastic model is identified by its Kolmo...

Abstract: We propose a class of random scale-free spatial networks with nested community structures and analyze Reed-Frost epidemics with community related independent transmissions. We show that the ...
Synchrony is one of the most common dynamical states emerging on networks. The speed of convergence towards synchrony provides a fundamental collective time scale for synchronizing systems. Here we st...
Compress-and-Forward Scheme for a Relay Network: Approximate Optimality and Connection to Algebraic Flows
Compress-and-Forward Scheme Relay Network Approximate Optimality Connection Algebraic Flows
