The impact of spatial data redundancy on SOLAP query performance
(Sociedade Brasileira de Computação, 2009)
Geographic Data Warehouses (GDW) are one of the main technologies used in decision-making processes and spatial analysis, and the literature proposes several conceptual and logical data models for GDW. However, little ...
SB-Index : um índice espacial baseado em bitmap para data warehouse geográfico
(Universidade Federal de São CarlosBRUFSCarPrograma de Pós-Graduação em Ciência da Computação - PPGCC, 2009-08-26)
Geographic Data Warehouses (GDW) became one of the main technologies used in decision-making processes and spatial analysis since they provide the integration of Data Warehouses, On-Line Analytical Processing and Geographic ...
Species-poor and low-lying sites are more ecologically unique in a hyperdiverse Amazon region: Evidence from multiple taxonomic groups
(2018-07-01)
Aim: We analysed beta-diversity patterns of various biological groups simultaneously, from the perspective of site ecological uniqueness. We also investigated whether ecological uniqueness variation could be explained by ...
Geographic patterns of vascular plant diversity and endemism using different taxonomic and spatial units
(MDPI, 2022)
Estimation of biodiversity patterns in poorly known areas is hampered by data availability and biased collecting efforts. To overcome the former, patterns can be estimated at higher taxonomic levels and larger spatial ...
Geographic Patterns of Vascular Plant Diversity and Endemism Using Different Taxonomic and Spatial Units
(MDPI, 2022)
Estimation of biodiversity patterns in poorly known areas is hampered by data availability and biased collecting efforts. To overcome the former, patterns can be estimated at higher taxonomic levels and larger spatial ...
Weighted sample variograms as a tool to better assess the spatial variability of soil properties
(2007)
Geostatistical estimation and simulation techniques are useful for characterizing the spatial distribution of soil properties. These techniques usually rely on a variogram model that measures the spatial variability of the ...
Latest Advances in Image Acceleration: All Dimensions are Fair Game
(2022)
Magnetic resonance imaging (MRI) is a versatile modality that can generate high-resolution images with a variety of tissue contrasts. However, MRI is a slow technique and requires long acquisition times, which increase ...
Partitioning multiple facets of beta diversity in a tropical stream macroalgal metacommunity
(2020-08-01)
Aim: We evaluated different facets of beta diversity (taxonomic, phylogenetic and functional), and its components (spatial turnover and nestedness), of a stream macroalgal metacommunity, as well as the effect of local ...
Comparing taxon- and trait-environment relationships in stream communities
(2020-10-01)
Traits define how organisms interact with their surrounding environment and with other organisms. Thus, trait composition of biological communities is expected to change predictably along environmental gradients. Because ...
Protocolo ciente de correlação espacial para redes de sensores sem fio
(Universidade Federal de São CarlosBRUFSCarPrograma de Pós-Graduação em Ciência da Computação - PPGCC, 2011-06-27)
The usage of wireless sensor network is increasingly being applied to people s everyday lives everywhere: from energy consumption in households and buildings in general, to vital signs in assistive medicine, infrastructure ...
