Distributed algorithms for control of demand response and distributed energy resources
(2011)This paper proposes distributed algorithms for control and coordination of loads and distributed energy resources (DERs) in distribution networks. These algorithms are relevant for load curtailment control in demand response ...

Distributed calculation of linear functions in noisy networks via linear iterations
(2008)Given a fixed network where each node has some given initial value, and under the constraint that each node receives noisy transmissions from its immediate neighbors, we provide a distributed scheme for any node to calculate ...

Distributed strategies for average consensus in directed graphs
(2011)We address the average consensus problem for a distributed system whose components (nodes) can exchange information via interconnections (links) that form an arbitrary, strongly connected but possibly directed, topology ...

Article
Efficient MFS algorithms for inhomogeneous polyharmonic problems
(2011)In this work we develop an efficient algorithm for the application of the method of fundamental solutions to inhomogeneous polyharmonic problems, that is problems governed by equations of the form Δ ℓ u=f, ℓ ε ℕ, in circular ...

Information dissemination in networks via linear iterative strategies over finite fields
(2009)Given an arbitrary network of interconnected nodes, each with an initial value from a discrete set, we consider the problem of distributively disseminating these initial values under the constraint that the nodes can only ...

Linear iterative strategies for transmitting streams of values through sensor networks
(2009)For any given fixed network of interconnected nodes, with some nodes designated as sources and some nodes designated as sinks, we investigate the problem of transmitting a stream of values from every source node to all of ...

The method of fundamental solutions in Threedimensional Elastostatics
(2002)We consider the application of the Method of Fundamental Solutions (MFS) to isotropic elastostatics problems in threespace dimensions. The displacements are approximated by linear combinations of the fundamental solutions ...

On the time complexity of information dissemination via linear iterative strategies
(2010)Given an arbitrary network of interconnected nodes, each with an initial value, we study the number of timesteps required for some (or all) of the nodes to gather all of the initial values via a linear iterative strategy. ...

Article
Optimal control of uncertain stochastic systems subject to total variation distance uncertainty
(2012)This paper is concerned with optimization of uncertain stochastic systems, in which uncertainty is described by a total variation distance constraint between the measures induced by the uncertain systems and the measure ...

Optimal stochastic control of discretetime systems subject to total variation distance uncertainty
(2010)This paper presents another application of the results in [1], [2], where existence of the maximizing measure over the total variation distance constraint is established, while the maximizing payoff is shown to be equivalent ...

Article
Series decomposition of fractional Brownian motion and its Lamperti transform
(2009)The Lamperti transformation of a selfsimilar process is a stationary process. In particular, the fractional Brownian motion transforms to the second order stationary Gaussian process. This process is represented as a ...

Stochastic optimal control subject to variational norm uncertainty: Viscosity subsolution for generalized HJB inequality
(2009)This paper is concerned with optimization of stochastic uncertain systems, when systems are described by measures and the payoff by a linear functional on the space of measure, on general abstract spaces. Robustness is ...

The wireless control network: Monitoring for malicious behavior
(2010)We consider the problem of stabilizing a plant with a network of resource constrained wireless nodes. In a companion paper, we developed a protocol where each node repeatedly transmits an appropriate (stabilizing) linear ...
