Analysing Pine Disease Spread Using Random Point Process by Remote Sensing of a Forest Stand

open access: yesRemote Sensing, 2023
The application of a process model to investigate pine tree infestation caused by bark beetles is discussed. The analysis of this disease was carried out using spatial and spatio−temporal models of random point patterns.

Signal from noise retrieval from one and two-point Green's function - comparison

open access: yes, 2015
We compare two methods of eigen-inference from large sets of data, based on the analysis of one-point and two-point Green's functions, respectively. Our analysis points at the superiority of eigen-inference based on one-point Green's function. First, the

Orthogonal series estimation of the pair correlation function of a spatial point process

open access: yes, 2017
The pair correlation function is a fundamental spatial point process characteristic that, given the intensity function, determines second order moments of the point process.

FE-Meshfree QUAD4 Element with Modified Radial Point Interpolation Function for Structural Dynamic Analysis

open access: yesShock and Vibration, 2019
The partition-of-unity method based on FE-Meshfree QUAD4 element synthesizes the respective advantages of meshfree and finite element methods by exploiting composite shape functions to obtain high-order global approximations.

Poincaré constraints on celestial amplitudes

open access: yesJournal of High Energy Physics, 2020
The functional structure of celestial amplitudes as constrained by Poincare symmetry is investigated in 2, 3, and 4-point cases for massless external particles of various spin, as well as massive external scalars.

Point spread function shaping using geometric analysis [PDF]

open access: yesOptics Communications, 2018
Abstract We present a method for shaping point spread functions (PSF) into simple geometric shapes that are free of noise or speckles. The derived phase distributions are intended for typical 2f setups used for reading out computer generated holograms (CGH).

Covariant Formulation of the Invariant Measure for the Mixmaster Dynamics [PDF]

open access: yes, 2001
We provide a Hamiltonian analysis of the Mixmaster Universe dynamics showing the covariant nature of its chaotic behavior with respect to any choice of time variable.

Correction for the Partial Volume Effects (PVE) in Nuclear Medicine Imaging: A Post-Reconstruction Analytic Method

open access: yesApplied Sciences, 2021
Quantitative analyses in nuclear medicine are increasingly used, both for diagnostic and therapeutic purposes. The Partial Volume Effect (PVE) is the most important factor of loss of quantification in Nuclear Medicine, especially for evaluation in Region
