Compact representation of solution vectors in Kroneckerbased Markovian analysis
(Springer Verlag, 2016)It is well known that the infinitesimal generator underlying a multidimensional Markov chain with a relatively large reachable state space can be represented compactly on a computer in the form of a block matrix in which ... 
Decompositional analysis of Kronecker structured Markov chains
(Kent State University, 2008)This contribution proposes a decompositional iterative method with low memory requirements for the steadystate analysis ofKronecker structured Markov chains. The Markovian system is formed by a composition of subsystems ... 
A distancelimited continuous locationallocation problem for spatial planning of decentralized systems
(Elsevier, 2017)We introduce a new continuous locationallocation problem where the facilities have both a fixed opening cost and a coverage distance limitation. The problem has wide applications especially in the spatial planning of water ... 
Effective preconditioners for large integralequation problems
(2007)We consider effective preconditioning schemes for the iterative solution of integralequation methods. For parallel implementations, the sparse approximate inverse or the iterative solution of the nearfield system enables ... 
On the analyticity of functions approximated by their qBernstein polynomials when q > 1
(2010)Since in the case q > 1 the qBernstein polynomials Bn,q are not positive linear operators on C[0, 1], the investigation of their convergence properties for q > 1 turns out to be much harder than the one for 0 < ... 
Optimal representation of nonstationary random fields with finite numbers of samples: A linear MMSE framework
(Elsevier, 2013)In this article we consider the representation of a finiteenergy nonstationary random field with a finite number of samples. We pose the problem as an optimal sampling problem where we seek the optimal sampling interval ... 
Parallel preconditioners for solutions of dense linear systems with tens of millions of unknowns
(2007)We propose novel parallel preconditioning schemes for the iterative solution of integral equation methods. In particular, we try to improve convergence rate of the illconditioned linear systems formulated by the electricfield ... 
Sequential and parallel preconditioners for Largescale integralequation problems
(2007)For efficient solutions of integralequation methods via the multilevel fast multipole algorithm (MLFMA), effective preconditioners are required. In this paper we review appropriate preconditioners that have been used for ... 
Superimposed event detection by sequential Monte Carlo methods
(2007)In this paper', we consider the detection of rare events by applying particle filtering. We model the rare event as an AR signal superposed on a background signal. The activation and deactivation times of the ARsignal are ...
