Analyzing monitoring data efficiently is a classic problem in structural health monitoring. A nonparametric test method, the Mann–Kendall (MK) was implemented this study, which commonly used to detect monotonic trends series of environmental data. Using MK three types time were studied: stress measured concrete prism compression test, resultant force obtained from pseudostatic reinforced masonr...
One of the most important hydrological time series task is to determine if there is any trend in the data and how to achieve stationarity when there is nonstationarity behavior in data. Detecting trend and stationarity in hydrological time series may help us to understand the possible links between hydrological processes and global climate changes. In this study yearly, monthly and daily stream...
In this paper, the variation of temperature and rainfall at Patna are analysed using simple non-parametric tests. The trends in annual maximum minimum daily temperatures, rainfall, number rainy days a year, average per day ratio to have been examined. Tends total monthly Highest month also determined for every year. data Mann-Kendall test indicated statistically significant changes pattern city.
Doroodzan Dam basin is one of the strategic agricultural areas in Fars province. Changes in time series of climatic parameters, especially temperature and precipitation parameters, can have a significant impact on the growth cycle of agricultural products, the status of water resources and the economy of the populations in the area. In the present study, rainfall and temperature trends were inv...
Any changes in the climate system affect on the access and management of natural resources such as water and soil. Temperature and precipitation are the key elements of climate for studying their trend can be important for atmospheric scientists, environmental managers and planners in the field of hydrology, agriculture, environment and so on. In this study, the trend of climate fluctuations wa...
The purpose of this study is to determine the long-term variations in rainfall data as well as to identify wet and dry periods of 35 synoptic stations in Iran. In order to know the variation of rainfall in studied stations, average maps, coefficient of variation and skewness were drawn. Then, using the Mann-Kendall test, the significance of the trend on each station was tested at 95% confidence...
Two-loop Gell-Mann–Low function of N=1 supersymmetric Yang-Mills theory, regularized by higher covariant derivatives. Abstract Two-loop Gell-Mann–Low function is calculated for N=1 supersymmetric Yang– Mills theory, regularized by higher covariant derivatives. The integrals, which define it, are shown to be reduced to total derivatives and can be easily calculated analytically .
The social, economic, and ecological importance of the aquifer system within Bacchiglione basin (Veneto, IT) is noteworthy, there considerable disagreement among previous studies over its sustainable use. Investigating long-term quantitative sustainability groundwater system, this study presents a statistical methodology that can be applied to similar cases. Using combination robust widely used...
The wind is one of the most important and studied variables globally, essential to several sectors, for example, energy. Therefore, this study assesses regime analysis trends in three locations within Paraná state, Brazil. historical series were recorded between 1976 2010 at conventional meteorological stations belonging Brazilian National Institute Meteorology. WRPLOT version 8.0.0 software wa...
