Analytic residues along algebraic cycles
(2005)Let W be a qdimensional irreducible algebraic subvariety in the affine space A C n, P1,..., Pm m elements in C[X1,...,Xn], and V(P) the set of common zeros of the Pj's in C n. Assuming that W is not included in V(P), one ...

Distributed function calculation via linear iterations in the presence of malicious agents  Part II: Overcoming malicious behavior
(2008)Given a network of interconnected nodes, each with a given initial value, we develop a distributed strategy that enables some or all of the nodes to calculate any arbitrary function of these initial values, despite the ...

Examples of optimal control for nonlinear stochastic control problems with partial information
(IEEE, 1995)Partially observable stochastic optimal control problems are considered. It is shown, via an information state approach and dynamic programming, that several classes of nonlinear systems with nonlinearities in the dynamics ...

Faulttolerant semi fast implementations of atomic read/write registers
(2006)This paper investigates timeefficient implementations of atomic readwrite registers in messagepassing systems where the number of readers can be unbounded. In particular we study the case of a single writer, multiple ...

First passage risksensitive criterion for stochastic evolutions
(1995)The purpose of this paper is to investigate in an infinite dimensional space, the first passage problem with a risksensitive performance criterion, and to illustrate the asymptotic behavior of the associated value function, ...

Marking observer in labeled petri nets with application to supervisory control
(2017)In this paper, we consider the problem of marking estimation in labeled Petri nets whose initial marking is known to belong to a given convex set, in the presence of silent transitions (i.e., transitions labeled with the ...

Marking observer of labeled petri nets with uncertainty in the initial marking
(2013)In this paper we consider marking estimation in labeled Petri nets whose initial marking is known to belong to a given convex set. We allow for silent transitions (i.e., transitions labeled with the empty word) and ...

Minimizing outage probability for a class of MIMO channels
(2009)In this paper we investigate the outage probability of MultipleInput MultipleOutput (MIMO) channels, when the probability distribution of the channel gains is not completely known to the transmitter and receiver. The ...

Modeling change of haplotype distributions in random mating populations using random sets
(2004)Several mathematical models have been developed to describe the genetic structure of populations. Most of these models focus on only one, or few genetic loci. In this paper, we develop a model to describe a large number ...

Article
Multilevel characterizations of anisotropic function spaces
(2005)We present a general method for extending decomposition systems of L 2(ℝd) to decomposition systems for the anisotropic TriebelLizorkin and Besov spaces, Fp,qα,s and Bp,qα,s, respectively, for the full range of the indexes. ...

Article
On efficient AR spectral estimation for longrange predictions
(2005)This article discusses the concept of asymptotic efficiency from the frequency domain point of view making use of the direct method for multiple prediction. In particular, it is shown that with the use of a new autoregressive ...

Optimal measurement strategy for nonlinear filtering
(2006)In this paper we consider the question of an optimal measurement strategy for nonlinear filtering. Given a set of measurement and observation options, the problem faced by a designer is to choose the option that gives the ...
