Linking numbers of measured foliations
, 2001 We generalise the average asymptotic linking number of a pair of divergence-free vector fields on homology three-spheres by considering the linking of a divergence-free vector field on a manifold of arbitrary dimension with a codimension two foliation ...

Entropy based adaptive particle filter [PDF]
, 2006 We propose a particle filter for the estimation of a partially observed Markov chain that has a non dynamic component. Such systems arise when we include unknown parameters or when we decompose non ergodic systems to their ergodic classes.

High Order Conformal Symplectic and Ergodic Schemes for the Stochastic Langevin Equation via Generating Functions [PDF]
SIAM Journal on Numerical Analysis, 2017 In this paper, we consider the stochastic Langevin equation with additive noises, which possesses both conformal symplectic geometric structure and ergodicity.

CDF-Based Multiuser Scheduling for Downlink Non-Orthogonal Multiple Access (NOMA)
IEEE Access, 2020 In this paper, we propose cumulative distribution function (CDF)-based multiuser scheduling (CMS) for downlink non-orthogonal multiple access (NOMA) to accommodate a massive number of IoT devices over limited radio resources and statistically analyze the

Quantum unique ergodicity for parabolic maps
, 1999 We study the ergodic properties of quantized ergodic maps of the torus. It is known that these satisfy quantum ergodicity: For almost all eigenstates, the expectation values of quantum observables converge to the classical phase-space average with ...

Fluctuations of ergodic averages
Illinois Journal of Mathematics, 1999 The goal of the paper is to get some universal estimates for the probability that there are many fluctuations in the ergodic averages. The methods involve an effective Vitali type covering theorem and are valid for \(\mathbb{Z}^d\) actions, for any \(d\in\mathbb{N}\). Theorem.

EURASIP Journal on Wireless Communications and Networking, 2007 Optimal design of a linear antenna array with nonuniform interelement spacings is investigated for the uplink of a cellular system. The optimization criterion considered is based on the minimization of the average interference power at the output of a ...

Distributed Event-Triggered Subgradient Method for Convex Optimization With General Step-Size
IEEE Access, 2020 In this paper, the consensus and optimization of a multiagent system in a distributed optimization problem with bounded constraint is discussed under the general step-size, which is square nonsummable.

Canadian Journal of Statistics, EarlyView.Abstract We establish the consistency and the asymptotic distribution of the least squares estimators of the coefficients of a subset vector autoregressive process with exogenous variables (VARX). Using a martingale central limit theorem, we derive the asymptotic normal distribution of the estimators. Diagnostic checking is discussed using kernel‐based
