A spatial analysis of multivariate output from regional climate models [PDF]

open access: yes, 2011
Climate models have become an important tool in the study of climate and climate change, and ensemble experiments consisting of multiple climate-model runs are used in studying and quantifying the uncertainty in climate-model output.

Morphological Responses of Viola Accessions to Nutrient Solution Application and Electrical Conductivity

open access: yesPlants, 2022
Growing of ornamental flowering plants represents an important sector of horticulture. Viola × wittrockiana (garden pansy) is used in garden beds and borders due to their colorful blooming, which occurs in early spring and late autumn. Nowadays, breeders

New Algorithms for $M$-Estimation of Multivariate Scatter and Location [PDF]

open access: yes, 2015
We present new algorithms for $M$-estimators of multivariate scatter and location and for symmetrized $M$-estimators of multivariate scatter. The new algorithms are considerably faster than currently used fixed-point and related algorithms. The main idea

Evaluation of Facility Management by Multivariate Statistics – Factor Analysis

open access: yesSelected Scientific Papers: Journal of Civil Engineering, 2013
Facility management is evolving, there is no exact than other sciences, although its development is fast forward. The knowledge and practical skills in facility management is not replaced, on the contrary, they complement each other.

Avaliação da concentração de alguns íons metálicos em diferentes espécies de líquens do cerrado Sul-Mato-Grossense Evaluation of concentration of some metal ions in different lichen species of the Sul-Mato-Grossensse cerrado

open access: yesQuímica Nova, 2007
Concentrations of Fe, Mn, Co, Cr, Zn and Cu were determinated using flame atomic absorption spectrometry in nine lichen species of the Sul-Mato-Grossense cerrado. The average metal ion concentrations varied in the following ranges: Fe, 248.41-1568.01; Mn,

Wearable Electromagnetic Belt for Steatotic Liver Detection Using Multivariate Energy Statistics

open access: yesIEEE Access, 2020
A wearable electromagnetic belt system for the detection of hepatic steatosis (lipid accumulation within the major liver cells, hepatocytes), is proposed. To satisfy the requirements of the belt system, an array of body matched antennas is designed.

On high-dimensional sign tests

open access: yes, 2016
Sign tests are among the most successful procedures in multivariate nonparametric statistics. In this paper, we consider several testing problems in multivariate analysis, directional statistics and multivariate time series analysis, and we show that ...

Optimal and fast detection of spatial clusters with scan statistics [PDF]

open access: yes, 2010
We consider the detection of multivariate spatial clusters in the Bernoulli model with $N$ locations, where the design distribution has weakly dependent marginals.

Canonical correlation between clogging agents and performance of drippers operating with aquaculture effluents [PDF]

open access: yesRevista Brasileira de Engenharia Agrícola e Ambiental
The canonical correlation is used to correlate groups of distinct variables. The objective of this study was to use canonical correlation analysis to evaluate the interaction between water quality attributes clogging-causing and the hydraulic performance
