A number-average property such as a number-average diffusion constant D n cannot be defined in terms of weight-related weighting factors (such as concentrations in weight per unit volume) without postulating a functional relationship between the molecular weight and that property. Conversely, an ...
"self-convergence of weighed average".Beginning with the basic conceptualism,an optimizing mode is employed to decide weight in general condition and obtained a series of weight methods of covariance matrix which is positive matrix.At last a perfect set of theories to decide the weight is ...

Most preferably, cis-polybutadiene having a weight-average molecular weight of from about 100,000 to about 500,000 is employed. Along this line, it has been found that the high cis-polybutadiene manufactured and sold by Shell Chemical Co., Houston, Tex., under the tradename Cariflex BR-...
in mathematics, the weighted mean is one of the types to calculate the average of the values. the weighted mean is also known as the weighted average. in the weighted mean, the average value can be calculated by providing different weights to some of the individual values. if all the ...
For the approximation problem, the proofs are constructive. For integration, general upper bounds are obtained by using Monte Carlo arguments. 关键词: Gaussian process average error complexity weighted approximation weighted integration DOI: 10.1007/978-3-642-56046-0_31 被引量: 14 年份: 2002 ...
Indeed, by regarding ρ0 (r) as the overall “investment” and ρ(r) as the overall “profit” the AIM participation in the molecular profit is seen to be equal to its share in the overall investment. One finds the atomic average numbers of electrons by integrating the subsystem densities...
Variance components and heritability of the studied traits were estimated using average information restricted maximum likelihood (AI-REML) method25 via pedigree data. Marker effects and further weights required for constructing G matrix were calculated in an iterative way proposed by Wang et al.10,26...
average trapping time (ATT) with a given target node. Although some efforts have been made with several weighted and directed models38,39,40,41, additional work is needed to deepen the understanding of the impact of the weight and direction on random walks. Below, we first propose a ...
