Revised Test for Stochastic Diagnosability of Discrete-Event Systems
(2018)This paper provides revisions to the algorithms presented by Chen et al., 2013 for testing diagnosability of stochastic discrete-event systems. Additional new contributions include PSPACE-hardness of verifying strong ...

Sigma- Terms and axial charges for hyperons and charmed baryons
(Proceedings of Science (PoS), 2013)We present results for the s- Terms and axial charges for various hyperons and charmed baryons using Nf = 2+1+1 twisted mass fermions. For the computation of the three-point function we use the fixed current method. For ...

Signalling of information in networked stochastic dynamical control systems
(Institute of Electrical and Electronics Engineers Inc., 2018)Signalling of information is made feasible from one controller to another controller, in a networked control system consisting of two interconnected control systems. In this application, controller 2 of control system 2 ...

A spatiotemporal precipitation generator based on a censored latent Gaussian field
(2015)A daily stochastic spatiotemporal precipitation generator that yields precipitation realizations that are quantitatively consistent is described. The methodology relies on a latent Gaussian field that drives both the ...

Stochastic control over finite capacity channels: Causality and feedback
(Institute of Electrical and Electronics Engineers Inc., 2014)Optimal communication/control analysis and design of dynamical controlled systems, when there are finite capacity communication constraints often involve information and control theoretic analysis. This paper, employees ...

Stochastic minimum principle for partially observed systems subject to continuous and jump diffusion processes and driven by relaxed controls
(2013)In this paper, we consider nonconvex control problems of stochastic differential equations driven by relaxed controls adapted, in the weak star sense, to a current of sigma algebras generated by observable processes. We ...

Stochastic optimal control subject to variational norm uncertainty: Dynamic programming and HJB equation
(Institute of Electrical and Electronics Engineers Inc., 2014)This paper is concerned with the application of recent results in optimization of stochastic uncertain systems on general abstract spaces, when the uncertain probability measure of the system is described by a ball with ...

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 pay-off by a linear functional on the space of measure, on general abstract spaces. Robustness is ...

Stochastic power control for time-varying flat fading wireless channels
(2005)The performance of stochastic optimal power control of time-varying wireless short-term flat fading channels, in which the evolution of the dynamical channel is described by a stochastic state space representation, is ...

A study of the radiative transition ππ → πγ∗ with lattice QCD
(Proceedings of Science (PoS), 2016)Lattice QCD calculations of radiative transitions between hadrons have in the past been limited to processes of hadrons stable under the strong interaction. Recently developed methods for 1 → 2 transition matrix elements ...

A sufficient condition for decentralized non-cooperative stochastic differential games and relations to mean field games
(Institute of Electrical and Electronics Engineers Inc., 2015)In this paper we use martingale techniques to derive a sufficient condition for existence of decentralized strategies in non-cooperative stochastic differential games. The sufficient condition is given by decentralized ...

Symmetry analysis of a model of stochastic volatility with time-dependent parameters
(2011)We provide the solutions for the Heston model of stochastic volatility when the parameters of the model are constant and when they are functions of time. In the former case, the solution follows immediately from the ...

Team optimality conditions of distributed stochastic differential decision systems with decentralized noisy information structures
(2017)A team problem formulation of distributed stochastic differential systems with decentralized noisy information structures is considered, and a stochastic Pontryagin's maximum principle is applied to derive sufficient team ...

Verification of detectability in Probabilistic Finite Automata
(2017)In this paper we analyze state estimation in stochastic discrete event systems (SDES) that can be modeled as probabilistic finite automata (PFAs). For a given PFA, we obtain the necessary and sufficient conditions that ...
