Topographic–Vegetation Interactions on an Incipient Foredune Field Post-Tropical Storm

GeoHazards
Sand dunes protect the most important economic and ecologically critical landscapes from coastal hazards (storms and high-tide flooding). The characteristics of the dune affect their protective ability.

A New Model for the Stochastic Point Reactor: Development and Comparison with Available Models

Energies, 2021
The point kinetic model is a system of differential equations that enables analysis of reactor dynamics without the need to solve coupled space-time system of partial differential equations (PDEs). The random variations, especially during the startup and

Quasi-Symmetries of Determinantal Point Processes [PDF]

, 2016
The main result of this paper is that determinantal point processes on the real line corresponding to projection operators with integrable kernels are quasi-invariant, in the continuous case, under the group of diffeomorphisms with compact support ...

Partially Observed Two-Phase Point Processes

Axioms
In this paper, a two-phase spatio-temporal point process (STPP) defined on a countable metric space and characterized by a conditional intensity function is introduced.

Compound Poisson point processes, concentration and oracle inequalities

Journal of Inequalities and Applications, 2019
This note aims at presenting several new theoretical results for the compound Poisson point process, which follows the work of Zhang et al. (Insur. Math. Econ. 59:325–336, 2014).

Limit theory for point processes in manifolds

, 2013
Let $Y_i,i\geq1$, be i.i.d. random variables having values in an $m$-dimensional manifold $\mathcal {M}\subset \mathbb{R}^d$ and consider sums $\sum_{i=1}^n\xi(n^{1/m}Y_i,\{n^{1/m}Y_j\}_{j=1}^n)$, where $\xi$ is a real valued function defined on pairs ...

State-Dependent Fractional Point Processes [PDF]

Journal of Applied Probability, 2015
In this paper we analyse the fractional Poisson process where the state probabilities pkνk(t), t ≥ 0, are governed by time-fractional equations of order 0 < νk ≤ 1 depending on the number k of events that have occurred up to time t. We are able to obtain explicitly the Laplace transform of pkνk(t) and various representations of state probabilities ...

Rate-Distortion Theory of Finite Point Processes

, 2018
We study the compression of data in the case where the useful information is contained in a set rather than a vector, i.e., the ordering of the data points is irrelevant and the number of data points is unknown.

Approximate Inference in Continuous Determinantal Point Processes [PDF]

, 2013
Determinantal point processes (DPPs) are random point processes well-suited for modeling repulsion. In machine learning, the focus of DPP-based models has been on diverse subset selection from a discrete and finite base set.
