Land condition assessment is a basic prerequisite for finding the degradation of a territory, which might lead to desertification under climatic and human pressures. The temporal change in vegetation productivity is a key indicator of land degradation. In this paper, taking the Otindag Sandy Land as a case, the mean normalized difference vegetation index (NDVI_a), net primary production (NPP) a...

in this study, long-term trends and abrupt changes of hydro-climatic variables was investigated in the observed period 1971-2000 for aidoghmoush basin using mann-kendall nonparametric test and cumulative curve of climatic variables-runoff, respectively. results show decrease trends for rainfall and runoff and increase trend for temperature by the mann-kendall test with a confidence level of 99%...

This study was carried out to analyse the trend analysis of long-term annual and seasonal rainfall pattern in Telangana state, India. For this monthly data state from January 1982 December 2021 collected NASA power website (https://power.Iarc.nasa.gov). The linear regression line non-parametric tests, such as Mann-Kendall test, Modified-Mann Kendall test Innovative were used understand present ...

Piecewise Linear Representation has been widely used to compress online data which are collected by sensors. However, the current existing methods, including Piecewise Aggregate Approximation and Perceptually Important Points cannot own both advantages of calculation speed and recovery accuracy at the same time. In order to improve the Piecewise Linear Representation performance, this work prop...
