A Random Dynamical Systems Approach to Filtering in Large-scale Networks
S. Kar, B. Sinopoli, J. M. F. Moura
The paper studies the problem of filtering a discrete-time linear system observed by a network of sensors. The sensors share a common communication medium to the estimator and tran…
MACH: Fast Randomized Tensor Decompositions
Charalampos E. Tsourakakis
Tensors naturally model many real world processes which generate multi-aspect data. Such processes appear in many different research disciplines, e.g, chemometrics, computer vision…
Consensus in Correlated Random Topologies: Weights for Finite Time Horizon
Dusan Jakovetic, Joao Xavier, Jose' M. F. Moura
We consider the weight design problem for the consensus algorithm under a finite time horizon. We assume that the underlying network is random where the links fail at each iteratio…
Using Resonances to Control Chaotic Mixing within a Translating and Rotating Droplet
Rodolphe Chabreyrie, Dmitri Vainchtein, Cristel Chandre +2
Enhancing and controlling chaotic advection or chaotic mixing within liquid droplets is crucial for a variety of applications including digital microfluidic devices which use micro…
Homogeneous Bubble Nucleation driven by local hot spots: a Molecular Dynamics Study
Zun-Jing Wang, Chantal Valeriani, Daan Frenkel
We report a Molecular Dynamics study of homogenous bubble nucleation in a Lennard-Jones fluid. The rate of bubble nucleation is estimated using forward-flux sampling (FFS). We find…
Markov equivalence for ancestral graphs
R. Ayesha Ali, Thomas S. Richardson, Peter Spirtes
Ancestral graphs can encode conditional independence relations that arise in directed acyclic graph (DAG) models with latent and selection variables. However, for any ancestral gra…
