The classification of unmanned aerial vehicle hyperspectral images is great significance in agricultural monitoring. This paper studied a fine method for crops based on feature transform combined with random forest (RF). Aiming at the problem large number spectra and amount calculation, three methods dimensionality reduction, minimum noise fraction (MNF), independent component analysis (ICA), p...

To evaluate the time course of EMG frequency changes during a three-minute maximal effort cycling test (3MT) session and to examine which parameter between mean (MNF) and median (MDF) frequency is more suitable for evaluation of changes in neuromuscular function throughout a 3MT. Eighteen recreationally-active men volunteered to participate in this study. Maximum voluntary contraction (MVC) was...

The purine bases absorbed (PBa) and microbial nitrogen flow (MNF) in the duodenum were estimated with five models proposed for sheep (1, 4), goats (2), cattle (5) and a goat-sheep mixed model (3). Data of purine derivatives excreted (PDe) in urine of eight digestibility trials were used. In these trials, eight adult male castrated Murciano-granadino goats (30.5 ± 4.95 kg of live weight) were us...

This paper develops a procedure for mapping Martian lithologic units, using the OMEGA/Mars Express data. The procedure consists of correcting Martian atmospheric absorptions based on an empirical transmission function method, noise-free principle components analysis based on a minimum noise fraction (MNF) method, lithologic unit delineation, and spectral matching of the units to spectral librar...

BACKGROUND There is not enough evidence to support the efficacy of massage for muscle fatigue despite wide utilization of the modality in various clinical settings. This study investigated the influence of massage application on localized back muscle fatigue. METHODS Twenty-nine healthy subjects participated in two experimental sessions (massage and rest conditions). On each test day, subject...

Impervious surfaces have been widely considered as the key indicator for evaluating urbanization and environmental quality. As one of most applied methods, spectral mixture analysis (SMA) has commonly used mapping urban impervious surface fractions. When implementing SMA, original multispectral remote-sensing reflectance images are served foundation to successful SMA. However, limited variances...
