Lamb Wave-Minimum Sampling Variance Particle Filter-Based Fatigue Crack Prognosis
Sensors, 2019 Fatigue cracks are one of the common failure types of key aircraft components, and they are the focus of prognostics and health management (PHM) systems. Monitoring and prediction of fatigue cracks show great application potential and economic benefit in

Succinct sampling from discrete distributions [PDF]
Proceedings of the forty-fifth annual ACM symposium on Theory of Computing, 2013 We revisit the classic problem of sampling from a discrete distribution: Given n non-negative w-bit integers x1,..,xn, the task is to build a data structure that allows sampling i with probability proportional to xi. The classic solution is Walker's alias method that takes, when implemented on a Word RAM, O(n) preprocessing time, O(1) expected query ...

A PSF Approach to Far Field Discretization for Conformal Sources
IEEE Access, 2022 Field sampling should be devised to preserve the information required for the knowledge of the radiation of an antenna. In this paper, we introduce a sampling scheme based on an inverse source problem approach to the far field radiated by a conformal ...

Sampling Discretization of the Uniform Norm
Constructive Approximation, 2023 Discretization of the uniform norm of functions from a given finite dimensional subspace of continuous functions is studied. We pay special attention to the case of trigonometric polynomials with frequencies from an arbitrary finite set with fixed cardinality.

Bias behaviour and antithetic sampling in mean-field particle approximations of SDEs nonlinear in the sense of McKean [PDF]
ESAIM: Proceedings and Surveys, 2019 In this paper, we prove that the weak error between a stochastic differential equation with nonlinearity in the sense of McKean given by moments and its approximation by the Euler discretization with time-step h of a system of N interacting particles is ...

THE DISCRETIZATION OF THE POLARIZED SIGNAL
Научный вестник МГТУ ГА, 2018 Often, the monitoring systems solution of remote sensing problems, recognition (classification, discrimination) of radar objects using radio polarimetry methods is required in real time mode with the display of the current information on the radar ...

Efficient Planar Near-Field Measurements for Radiation Pattern Evaluation by a Warping Strategy
IEEE Access, 2021 The sampling of the near-field radiated by a planar source observed over a finite planar aperture is addressed. To this end, we employ the warping method that amounts to properly change the observation variables and finding the sampling points as those ...

Sampling discretization and related problems [PDF]
Journal of Complexity, 2022 This survey addresses sampling discretization and its connections with other areas of mathematics. The survey concentrates on sampling discretization of norms of elements of finite-dimensional subspaces. We present here known results on sampling discretization of both integral norms and the uniform norm beginning with classical results and ending with ...
