Génération de semis de points fractals : une méthode du comptage de boites inversée

open access: yesCybergeo, 2015
Fractal dimension is useful to characterize the structure of spatial objects such as urban structures or river networks. However, fractal analysis is underutilized for point processes.

Generation of Granule Cell Dendritic Morphologies by Estimating the Spatial Heterogeneity of Dendritic Branching

open access: yesFrontiers in Computational Neuroscience, 2020
Biological realism of dendritic morphologies is important for simulating electrical stimulation of brain tissue. By adding point process modeling and conditional sampling to existing generation strategies, we provide a novel means of reproducing the ...

Local generalised method of moments: an application to point process-based rainfall models [PDF]

open access: yes, 2015
Long series of simulated rainfall are required at point locations for a range of applications, including hydrological studies. Clustered point process-based rainfall models have been used for generating such simulations for many decades.

Recognizing Patterns: Spatial Analysis of Observed Microbial Colonization on Root Surfaces

open access: yesFrontiers in Environmental Science, 2018
Root surfaces are major sites of interactions between plants and associated microorganisms. Here, plants and microbes communicate via signaling molecules, compete for nutrients, and release substrates that may have beneficial or harmful effects on each ...

Determinanti geografiche della mortalità per tumore tiroideo nella Sicilia orientale

open access: yesBollettino della Società Geografica Italiana, 2022
The study of geographic determinants in the processes of spreading infectious diseases has a long tradition. As a result of the increase in the incidence of chronic and non-infectious diseases, such as cancer and various types of heart disease ...

Optimizing carbon reduction strategies in Trinidad and Tobago’s power generation sector: insights from carbon emission pinch analysis

open access: yesCarbon Management
This study examines Trinidad and Tobago’s (T&T) efforts to expand energy capacity while reducing power-sector greenhouse gas (GHG) emissions from 2006 to 2030. Using a carbon-constrained energy planning (CCEP) framework and carbon emission pinch analysis

A Simultaneous Estimation of the Baseline Intensity and Parameters for Modulated Renewal Processes

open access: yesAxioms, 2022
This paper proposes a semiparametric solution to estimate the intensity (hazard) function of modulated renewal processes: a nonparametric estimate for the baseline intensity function together with a parametric estimate of the model parameters of the ...

Residual diagnostics for covariate effects in spatial point process models [PDF]

open access: yes, 2013
For a spatial point process model in which the intensity depends on spatial covariates, we develop graphical diagnostics for validating the covariate effect term in the model, and for assessing whether another covariate should be added to the model.

Cox Processes Associated with Spatial Copula Observed through Stratified Sampling

open access: yesMathematics, 2021
Cox processes, also called doubly stochastic Poisson processes, are used for describing phenomena for which overdispersion exists, as well as Poisson properties conditional on environmental effects.

Analysis of Extreme Peak Loads Using Point Processes: An Application Using South African Data

open access: yesIEEE Access, 2020
Extreme value modelling of peak load process is critical to the reliable specification of power generation, distribution and maintenance purposes during both peak and off-peak periods.
