abstract with due attention to importance of climate change and natural ecosystem sensibility of the study area, in this research have been studied the probable climatic departure from normal and the existence of trend in climatic time series is detected by statistical tests. the first on the basis of rank- method mann kendal, it is tried to identify of changes and then recognize their type and...

Streamflow processes of 12 rivers in western Europe are investigated for trend and nonstationarity in the full 100-year period in the 20 century. Trend analyses with Mann–Kendall test show that there is no trend in annual mean discharges. Only three annual maximum flow series exhibit significant trends (Rhine and Moselle, upward; Rhone, downward). There are two minimum flow series exhibiting si...

The Kendall (1955) rank correlation coefficient evaluates the degree of similarity between two sets of ranks given to a same set of objects. This coefficient depends upon the number of inversions of pairs of objects which would be needed to transform one rank order into the other. In order to do so, each rank order is represented by the set of all pairs of objects (e.g., [a,b] and [b,a] are the...

Extensive vegetation restoration projects have been widely implemented on the Loess Plateau, China, since 1998. In addition, increasing attention has been paid to the influence of revegetation on soil water. However, the response of the soil water content (SWC) to vegetation construction and management has not been adequately studied. In this study, three types of typical artificial vegetation ...

Comparing and ranking information is an important topic in social and information sciences, and in particular on the web. Its objective is to measure the difference of the preferences of voters on a set of candidates and to compute a consensus ranking. Commonly, each voter provides a total order of all candidates. In this work we consider the generalization of total orders and bucket orders to ...

abstract despite the significance of climate change assessment on regional planning of a basin, most of the previous researches have been focused on the point assessment of this phenomenon. this paper uses statistical tests as well as regional assessment to investigate the impact of climate change on the gorganroud-gharehsou basin. in this regard, various tests including man-kendall, cumulating...

Invented in the 1960’s, permutation codes have reemerged in recent years as a topic of great interest because of properties making them attractive for certain modern technological applications. In 2011 a decoding method called LP (linear programming) decoding was introduced for a class of permutation codes with a Euclidean distance induced metric. In this paper we comparatively analyze the Eucl...

In the revised manuscript we present improved examinations of the eventual link between air pressure variation and radon signals at the site. This was done by analysis in: a) the time domain by presenting statistical tests (Kendall rank test) of the relation between pressure and radon and the gradient of pressure and radon. b) the frequency domain – by presenting spectra of pressure and radon c...
