Extreme temperature of several stations in Malaysia is modelled by fitting the monthly maximum to the Generalized Extreme Value (GEV) distribution. The Mann-Kendall (MK) test suggests a non-stationary model. Two models are considered for stations with trend and the Likelihood Ratio test is used to determine the best-fitting model. Results show that half of the stations favour a model which is l...
based on the latest records of typhlops vermicularis merrem, 1820 from iran, this species is distributed in the northern and southern regions of the country. in this study, new records of typhlops vermicularis are presented and it is shown that distribution range of this species is extended towards the eastern and western iran, and according to the new distribution map, it can be assumed that t...
Given the importance of climate change issue, consideration of the climate and hydrological data trend has become very important. This study aimed to evaluate the effectiveness of different methods to remove the effect of autocorrelation in assessing the trend of parameters such as temperature, precipitation and discharge of the Eastern Gorganrood Basin, Golestan Province. For this purpose, in ...
Temperature and rainfall are important meteorological variables in connection with changes the climate. Analyzing temperature is a necessary first step determining how climate change will affect us. Evaluating would accessibility of water environment. The main focus current study on shifting patterns Kharun Watershed, Chhattisgarh. Mann-Kendall (MK) test Sen's slope (SS) method used this to exa...
In many quality control applications, the necessary distributional assumptions to correctly apply the traditional parametric control charts are either not met or there is simply not enough information or evidence to verify the assumptions. It is well known that performance of many parametric control charts can be seriously degraded in situations like this. Thus, control charts that do not requi...
Bhadradri district of the central Telangana zone is monsoon dependent as like our country in past three decades many changes and shifts rainfall was experienced by farming community. Hence, data (1991-2020) analyzed using non parametric statistical tests i.e Mann-Kendall (MK) test Sen’s slope estimator for determining trend magnitude. The Results study revealed that Z value annual significantly...
Abstract Studies detecting trends in climate elements typically concentrate on their local significance, ignoring the question whether significant may or not have occurred due to chance. The present paper fills this gap by examining several approaches statistical significance of defined a grid, that is regional scale. To end, we introduce novel simple procedure testing, which based counting sig...
in fact, this study focused on the following questions: 1. is there any difference between the effect of functional/notional approach and the structural approaches to language teaching on the proficiency test of efl learners? 2. can a rather innovative language test referred to as "functional test" ge devised so so to measure the proficiency test of efl learners, and thus be as much reliable an...
