Generalizing Ellipsoidal Growth [PDF]
Materials Research, 2019 This paper generalizes previous work of Rios and Villa on spherical growth. The generalized equation applies to nucleation of ellipsoids according to an inhomogeneous Poisson point process.

Uniform Deconvolution for Poisson Point Processes
J. Mach. Learn. Res., 2020 We focus on the estimation of the intensity of a Poisson process in the presence of a uniform noise. We propose a kernel-based procedure fully calibrated in theory and practice. We show that our adaptive estimator is optimal from the oracle and minimax points of view, and provide new lower bounds when the intensity belongs to a Sobolev ball.

IEEE Access, 2020 The evolution of the fifth-generation (5G)/ beyond 5G (B5G) mobile communication networks greatly depends on the seamless integration of terrestrial and sky networks over advanced multi-tier heterogeneous network (HetNet) infrastructure.

Rare Events and Poisson Point Processes [PDF]
Journal of Mathematical Sciences, 2020 The aim of the present work is to show that the results obtained earlier on the approximation of distributions of sums of independent terms by the accompanying compound Poisson laws may be interpreted as rather sharp quantitative estimates for the closeness between the sample containing independent observations of rare events and the Poisson point ...

MODELLING THE POSITION OF CELL PROFILES ALLOWING FOR BOTH INHOMOGENEITY AND INTERACTION
Image Analysis and Stereology, 2011 It is of interest to consider models for point processes that allow for interaction between the points as well as for inhomogeneity in the intensity of the points.

Journal of Materials Research and Technology, 2020 Analytical and numerical models of nucleation and growth transformations usually suppose that nuclei are located uniform randomly, i.e., according to a Poisson point process, within the matrix.

A Stochastic Geometry Approach to EMF Exposure Modeling
IEEE Access, 2021 Downlink exposure to electromagnetic fields due to cellular base stations in urban environments is studied using the stochastic geometry framework. A two-dimensional Poisson Point Process is assumed for the base station distribution.

The Cauchy–Schwarz Divergence for Poisson Point Processes [PDF]
IEEE Transactions on Information Theory, 2014 In this paper, we extend the notion of Cauchy-Schwarz divergence to point processes and establish that the Cauchy-Schwarz divergence between the probability densities of two Poisson point processes is half the squared $\mathbf{L^{2}}$-distance between their intensity functions. Extension of this result to mixtures of Poisson point processes and, in the

On the classification problem for Poisson point processes
Journal of Multivariate Analysis, 2017 We study the binary classification problem for Poisson point processes, which are allowed to take values in a general metric space. The problem is tackled in two different ways: estimating nonparametricaly the intensity functions of the processes (and then plugged into a deterministic formula which expresses the regression function in terms of the ...

Deterministic walk on Poisson point process
ESAIM: Proceedings and Surveys, 2017 A deterministic walk on a Poisson point process in Rd is an oriented graph where each point of the process is connected to only one other point following a deterministic and stationary rule of connection.
