Aiming at the lack of reliable gradual fault detection and abnormal condition alarm evaluation ability in plasticizing process single-base gun propellant, a diagnosis method based on normalized mutual information weighted multiway principal component analysis (NMI-WMPCA) under limited batch samples modelling was proposed. In this method, differences coupling correlation among multi-dimensional ...

The Weibel instability due to temperature anisotropy of electrons and ions in a plasma the presence cold warm is reported. Numerical calculations normalized growth rate are carried out when frequency electromagnetic waves greater than or less thermal velocity for typical existing parameters. increases with an increasing wave number, after attaining maxima, it decreases effects. Therefore, parab...

Measurements of carbon ̄ uxes in Arctic tundra landscapes are generally obtained through intensive ® eld work and involve the use of chamber and/or micrometeorological tower techniques. However, ® ndings in a variety of nonArctic ecosystems have demonstrated the potential of remote sensing-based techniques (particularly spectral vegetation indices) to provide estimates of CO2 exchange in amore ...

Abstract The optimum portfolio selection for an investor with particular preferences was proven to lie on the normalized efficient frontier between two bounds defined by the Ballestero (1998) bounding theorem. A deeper understanding is possible if the decision-maker is provided with visual and quantitative techniques. Here, we derive useful insights as a way to support investor?s decision-makin...

Terrestrial laser scanning (TLS) data can offer a means to estimate subcanopy fuel characteristics support site characterization, quantification of treatment or fire effects, and inform modeling. Using field TLS within the New Jersey Pinelands National Reserve (PNR), this study explores impact forest phenology density shrub height (i.e., bed depth) measurements on estimating average heights at ...

We investigate the waiting-time distribution of the absolute return in the Korean stock-market index KOSPI. We define the waiting time as a time interval during which the normalized absolute return remains continuously below a threshold rc. Through an exponential bin plot, we observe that the waiting-time distribution shows power-law behavior, pf (t) ∼ t−β , for a range of threshold values. The...

The use of by-plot coefficient of variation (CV) has not been evaluated in precision agricultural work. This study evaluated the relationship between CVs determined from normalized-difference vegetative index (NDVI) sensor readings, plant population, and sensing direction on NDVI values. Randomly selected plots, measuring 1 m2 (2003) and 3 m2 (2004), were established for this study. Plots in 20...
