Linear and non-linear trends for seasonal NO2 and SO2 concentrations in the Southern Hemisphere (2004−2016)
(Multidisciplinary Digital Publishing Institute, 2017-08)
In order to address the behaviour of nitrogen dioxide (NO2) and sulphur dioxide (SO2) in the context of a changing climate, linear and non-linear trends for the concentrations of these two trace gases were estimated over ...
Linear and non-linear trends for seasonal NO2 and SO2 concentrations in the southern hemisphere (2004-2016)
(MDPI, 2017)
Abstract: In order to address the behaviour of nitrogen dioxide (NO2) and sulphur dioxide (SO2) in the context of a changing climate, linear and non-linear trends for the concentrations of these two trace gases were estimated ...
Systematic sequencing of factorial experiments as an alternative to the random order
(2017-01-01)
The current study aims to discuss the use of systematic methods to generate experimental designs with good statistical properties and low costs. The research focuses on the sequence of experiments and on analysis the results ...

Estimation of Endogenous Volatility Models with Exponential Trends
(MDPI, 2022)
Nonlinearities, exponential trends, and Euler equations are three key features of standard dynamic volatility models of speculation, economic growth, or macroeconomic fluctuations with occasionally binding constraints and ...
Trends and Spatial Patterns of Drought Affected Area in Southern South America
(Molecular Diversity Preservation International, 2014-09)
Based on 56 rainfall stations, which cover the period 1961–2008, we analyzed the presence of trends in the drought-affected area over southern South America (SSA) at different time scales. In order to define drought ...
Planejamento de experimentos bayesianos: aplicações em experimentos na presença de tendências lineares

We present a general introduction in the construction of experimental design, spe-
cially a general factorial design and factorial design 2k and some Bayesian criteria in

Inter-annual and inter-decadal variability of dry days in Argentina
(Royal Meteorological Society, 2013-03)
This work proposes to employ the number of dry days (days without precipitation) as a variable of study, and to analyse their spatial and temporal variability in Argentina. Climatological aspects of dry days, such as their ...
Trend and recovery of the total ozone column in South America and Antarctica
(Springer, 2017)
South America is one of the most vulnerable areas to stratospheric ozone depletion; consequently, an increased amount of UV radiation reaches the Earth's surface in this region. In this study, we analyzed the long-term ...
