Multigrid methods have proven to be an invaluable tool efficiently solve large sparse linear systems arising in the discretization of Partial Differential Equations (PDEs). Algebraic multigrid and particular adaptive algebraic approaches shown that efficiency can obtained without having resort properties PDE. Yet required setup these poses a not negligible overhead cost. Methods from machine le...

Abstract. The simultaneous rise of tropical-cyclone-induced flood waters across a large hazard management domain can stretch rescue and recovery efforts. Here we present means to quantify the connectedness maximum surge during storm with geospatial statistics. Tide gauges throughout extensive estuaries barrier islands North Carolina deployed operating hurricanes Matthew (n=82) Florence (n=123) ...

Information about soil properties helps the farmers to adopt effective and efficient farming practices, which can increase higher yields with optimum usage of farm resources. An attempt has been made in this paper predict using geospatial kriging approaches. This study mainly focuses on predicting pH different methods. Soil dramatically affects many other processes, such as nitrification denitrifi...

This article models, through Geostatistics, a database with space-time characteristics seeking to examine climate variations in the state of Bahia located Northeast region Brazil. dataset consists information from 86 stations recorded by National Institute Meteorology (INMET) January 2010 December 2022 for state. The focus analysis was study time series data related air temperature. Initially, ...

To obtain regression parameter estimates in generalized estimation equation modeling, whether longitudinal or spatially correlated data, it is necessary to specify the structure of working correlation matrix. The can be affected by choice this Within spatial statistics, matrix also influences how variability modeled. Therefore, study proposes a new method for selecting matrix, based on conditio...

Precipitation estimation is a challenging task, especially in regions where its spatial distribution irregular and highly variable. This study evaluated the of annual rainfall semiarid Brazilian basin under different regimes impact on land use cover dynamics. Climate Hazards Group InfraRed with Stations (CHIRPS) records observed data from 40 weather stations over time series 55 years were used,...

ABSTRACT In precision agriculture, determining management zones for soil and plant attributes is a complex process that requires knowledge of several variables, which complicates decisionmaking processes. This study evaluated the spatial variability soybean yield chemical properties using geostatistical multivariate analyses to define in an Oxisol. The between 0 0.2 0.4 m depths were sampled at...

Tuberculosis is a contagious infectious disease caused by Mycobacterium tuberculosis. The risk level of transmission pulmonary tuberculosis with positive smear acid-resistant bacteria (BTA). BTA greater hight than negative smear. This study aims to predict areas the number new cases in Aceh Besar district spatially using kriging method. data used are secondary coordinate point each puskesmas pr...
