The angular and frequency correlation functions of the transmission coefficient for light propagation through a strongly scattering amplifying medium are considered. It is found that just as in the case of an elastic scattering medium the correlation function consists of three terms. However, the structure of the terms is rather different. Angular correlation has a power-law decay and exhibits ...

This paper introduces association norms of German noun compounds as a lexical-semantic resource for cognitive and computational linguistics research on compositionality. Based on an existing database of German noun compounds, we collected human associations to the compounds and their constituents within a web experiment. The current study describes the collection process and a part-of-speech an...

In order to predict storage life of navel orange, The model for the variable regularity of total soluble sugar, total acidity, vitamin C, soluble solids, the sugar-acidity ratio in navel orange according to storage time was established based on BP artificial neural network . The results show that the multi-factor BP artificial neural network model has better predicted effect than single-factor ...

IMLMS (interesting MLMS (Multiple Level Minimum Supports)) model, which was proposed in our previous works, is designed for pruning uninteresting infrequent and frequent itemsets discovered by MLMS model. One of the pruning measures used in IMLMS model, interest, can be described as follows: to two disjoint itemsets A,B, if interest(A,B)=|s(A∪B) s(A)s(B)|<mi, then A∪B is recognized as uninteres...

Two essential intuitions about the concept of multidimensional inequality have been highlighted in the emerging body of literature on this subject: first, multidimensional inequality should be a function of the uniform inequality of a multivariate distribution of goods or attributes across people (Kolm, 1977); and, second, it should also be a function of the cross-correlation between distributi...

A novel spatial modulation (SM) scheme suitable for correlated Rician fading scenario is proposed with the help of the key idea of Ungerboeck’s set partitioning. The motivation is based on the fact that the different error performance exists between the antenna domain and modulation signal domain in the traditional SM scheme. And the total system error performance is mainly determined by the wo...

Spearman’s rank correlation coefficient is a nonparametric (distribution-free) rank statistic proposed by Charles Spearman as a measure of the strength of an association between two variables. It is a measure of a monotone association that is used when the distribution of data makes Pearson’s correlation coefficient undesirable or misleading. Spearman’s coefficient is not a measure of the linea...

PURPOSE The level of the implant above the marginal bone and flap design have an effect on the bone resorption during the healing period. The aim of this study is to detect the relationship between the level of the implant at the implant placement and the bone level at the healing period in the mesial and distal side of implants placed with flapless (FL) and full-thickness flap (FT) methods. ...
