A Local Integral Equation Formulation Based on Moving Kriging Interpolation for Solving Coupled Nonlinear Reaction-Diffusion Equations

open access: yesAdvances in Mathematical Physics, 2014
The meshless local Pretrov-Galerkin method (MLPG) with the test function in view of the Heaviside step function is introduced to solve the system of coupled nonlinear reaction-diffusion equations in two-dimensional spaces subjected to Dirichlet and ...

Beyond Prediction: Data, Baselines, Explanation, and Causation in Machine Learning for Food Insecurity

open access: yesFood Safety and Health, EarlyView.
The gains from machine learning in nowcasting and forecasting food insecurity are still small and limited and cannot be observed in all countries. This review summarizes the public resources for data, corrects common misconceptions about model requirements, and establishes baseline requirements, explanations, causal inference, and equity in operational

High frequency modes meshfree analysis of Reissner–Mindlin plates

open access: yesJournal of Science: Advanced Materials and Devices, 2016
Finite element method (FEM) is well used for modeling plate structures. Meshfree methods, on the other hand, applied to the analysis of plate structures lag a little behind, but their great advantages and potential benefits of no meshing prompt continued

Bias Correction of ERA5 Temperature Across Five Topoclimatic Clusters: A Comparative Evaluation of Four Methods

open access: yesInternational Journal of Climatology, EarlyView.
ERA5 near‐surface temperature over South America exhibits systematic cold biases in daily maximum temperature and warm biases in daily minimum temperature. To address the continent's strong climatic and topographic heterogeneity, South America was partitioned into five topoclimatic clusters, and four bias‐correction approaches were evaluated. The Multi‐

Selection of the most appropriate interpolation method for sandstone reservoirs in the Kloštar oil and gas field

open access: yesGeologia Croatica, 2008
The distribution of porosity data collected at the Kloštar field is analysed. This field is located in the north-western part of the Sava depression, and represents one of the most long-standing fields with respect to oil production in Croatia ...

Climatic Drivers of the Area Burned by Winter Wildfires in Northern Italy

open access: yesInternational Journal of Climatology, EarlyView.
This study investigates winter wildfires occurring between November and April in northern Italy over the period 2008–2022. By integrating high‐resolution burned‐area data with gridded climatic indices derived from 150 weather stations, it identifies spatial and temporal wildfire patterns, highlights the most fire‐prone mountain areas through pixel ...

Kriging: a method of interpolation for geographical information systems.

open access: yes, 1990
Geographical information systems could be improved by adding procedures for geostatistical spatial analysis to existing facilities. Most traditional methods of interpolation are based on mathematical as distinct from stochastic models of spatial ...

Time series analysis on the appropriate time for malaria residual spraying based on Anopheles abundance, temperature, and precipitation between 2009 - 2016 in Kazerun, south of Iran. [PDF]

open access: yesJournal of Health Sciences and Surveillance System, 2018
Background: Malaria is one of the most important vector-borne diseases, a major health problem, and a serious cause of mortality around the world. Indoor Residual Spraying (IRS) together with insecticide-treated nets is among the primary methods used for
