MULTIVARIATE ANALYSIS OF PEANUT MECHANIZED HARVESTING [PDF]

open access: yesEngenharia AgrĂ­cola, 2018
The peanuts harvesting mechanization is affected by the soil physical characteristics and it may increase the losses due to the production of pods in subsurface.

Multivariate analysis of hydrophobic descriptors

open access: yesADMET and DMPK, 2014
Multivariate approaches like principal component analysis (PCA) are powerful tools to investigate hydrophobic descriptors and to discriminate between intrinsic hydrophobicity and polar contributions as hydrogen bonds and other electronic effects.

Analysis of Modulated Multivariate Oscillations

open access: yes, 2011
The concept of a common modulated oscillation spanning multiple time series is formalized, a method for the recovery of such a signal from potentially noisy observations is proposed, and the time-varying bias properties of the recovery method are derived.

Special section on modern multivariate analysis

open access: yes, 2012
A critically challenging problem facing statisticians is the identification of a suitable framework which consolidates data of various types, from different sources, and across different time frames or scales (many of which can be missing), and from ...

Gravitational-Wave Detection using Multivariate Analysis

open access: yes, 2013
Searches for gravitational-wave bursts (transient signals, typically of unknown waveform) require identification of weak signals in background detector noise. The sensitivity of such searches is often critically limited by non-Gaussian noise fluctuations

Multivariate Generalized Multiscale Entropy Analysis

open access: yesEntropy, 2016
Multiscale entropy (MSE) was introduced in the 2000s to quantify systems’ complexity. MSE relies on (i) a coarse-graining procedure to derive a set of time series representing the system dynamics on different time scales; (ii) the computation of the ...

Permutation inference methods for multivariate meta-analysis

open access: yes, 2019
Multivariate meta-analysis is gaining prominence in evidence synthesis research because it enables simultaneous synthesis of multiple correlated outcome data, and random-effects models have generally been used for addressing between-studies ...

Multivariate groundwater drought analysis using copulas

open access: yesHydrology Research, 2020
Drought characteristics are among major inputs in the planning and management of water resources. Although numerous studies on probabilistic aspects of meteorological drought characteristics and their joint distribution functions have been reported ...
