Based on the classic probability of edge(POE) metrics for quantifying background clutter,and the up-to-date research findings in human visual perception,a new method for modifying NVESD's classic human target acquisition performance was proposed. And the modified model was preliminarily validated.

In order to understand the process of ultra-fine comminuting mica with high pressurewater jet, the particle characteristic equation is deducted in this paper with assumption thatthe developing probability of edge crack,surface crack or volume crack in a particle is independant, and that the probbility of any crack developing in a particle is submitted to PoissonDistribution.

Due to the uncertainty of edge decision, a soft-decision method is employed to decide which denoising technique can be applied to the wavelet coefficient by the probability of edge.

A possible contribution of steel chemistry and heating temperature to changes in the steel phase composition and the probability of edge cracking is discussed.

The probability of edge-to-face random collisions is larger in this pH region, too, than that of the face-to-face collisions of lamellae.

In order to understand the process of ultra-fine comminuting mica with high pressurewater jet, the particle characteristic equation is deducted in this paper with assumption thatthe developing probability of edge crack,surface crack or volume crack in a particle is independant, and that the probbility of any crack developing in a particle is submitted to PoissonDistribution. It is considered that the developing probability of crack is proportional directlyto pressure, and inversely to feed mean particle size. Also, the experimental data of comminuting mica with water jet have been analysed, with the particle characteristic equation. Itis found that comminuting mica with water jet is mainly caused by edge crack developing,and particle size distribution depends on pressure and feed mean particle size.

Ecotone is zones of transition between adjacent ecological systems, having a set of characteristics uniquely defined by space and time scales and by the strength of the interactions between adjacent ecological systems. It situated where the rate and the dimension of ecological transfers (solar energy, nutrient exchange) have an abrupt change. Ecotonal ecosystems are characterizes by (1) permeability and vector diffusion;(2) semi-permeable membranes function and modification;(3) relative high instability and...

Ecotone is zones of transition between adjacent ecological systems, having a set of characteristics uniquely defined by space and time scales and by the strength of the interactions between adjacent ecological systems. It situated where the rate and the dimension of ecological transfers (solar energy, nutrient exchange) have an abrupt change. Ecotonal ecosystems are characterizes by (1) permeability and vector diffusion;(2) semi-permeable membranes function and modification;(3) relative high instability and volatility;(4) a wider amplitude of fluctuating physical and biological processes in arid zone ecosystems;(5) critical threshold. Ecotones of desert-oasis exist at every scale. The structural variables important to ecotones are size, shape, biological structure, structural constraint, internal heterogeneity, ecotone density, fractal dimension, patch diversity and mean patch size. The function of ecotones among desert and oasis are stated, such as passive diffusion, active diffusion, probability of edge encounter and probability of crossing a boundary. The important functional variables are stability, resilience, energetic, functional contrast and porosity. Finally, the future directions for the research of ecotone among desert and oasis are also presented.
