Time Series Analysis of Atmospheric Precipitation Characteristics in Western Siberia for 1979–2018 across Different Datasets

open access: yesAtmosphere, 2022
A comparative statistical analysis of the spatiotemporal variability of atmospheric precipitation characteristics (mean and extreme values) in Western Siberia was performed based on data acquired from meteorological stations, global precipitation ...

Water Quality of the Țiganilor River Catchment in Cluj Napoca [PDF]

open access: yesAerul şi Apa: Componente ale Mediului, 2020
The Țiganilor River catchment covers both built areas and the green/natural areas of the Botanical Garden. As we will see, the location influences differentially the quantitative and qualitative hydric processes of the stream.

Development of Intensity-Duration-Frequency Curves of Intense Rainfall With Emphasis on the Behavior of the Upper Tail of the Distribution [PDF]

open access: yesRevista Brasileira de Meteorologia, 2022
The design and management of various hydraulic structures (such as stormwater drains, bridges and dams) require the estimation of rainfall with duration of a few minutes up to 24 h or more.

A New Discrete Analog of the Continuous Lindley Distribution, with Reliability Applications

open access: yesEntropy, 2020
In this paper, we propose and study a new probability mass function by creating a natural discrete analog to the continuous Lindley distribution as a mixture of geometric and negative binomial distributions.

Bayesian Inference in Extremes Using the Four-Parameter Kappa Distribution

open access: yesMathematics, 2020
Maximum likelihood estimation (MLE) of the four-parameter kappa distribution (K4D) is known to be occasionally unstable for small sample sizes and to be very sensitive to outliers.

Estimates of the statistical correlation between the extreme ice pressure patterns with various spatial resolution

open access: yesЛëд и снег, 2023
Ice pressure is characterized with significant spatial variability. Study of this variability with the help of in situ observations is rather difficult, because (1) the instrumental measurements are expensive and technically complicated, and, hence, the ...

Comparison and analysis of investigation results on volumetric activity of 137Cs at the Baltic Sea coast in 2003–2005

open access: yesJournal of Environmental Engineering and Landscape Management, 2007
Measurements of 137Cs volumetric activity (VA) in coastal waters of the Baltic Sea (near Juodkrante) were carried out in 2005. The highest values occurred in springtime; later they decreased, and in the summer‐autumn period approximate homogeneous values
