(Community Ecology, 2018-06-01) [Artigo]
The knowledge of the decomposition of macrophytes and associated organisms is important to understand ecological processes that control aquatic ecosystem metabolism. The aims of the study were: 1) to investigate the structure ...
Factorial and response surface designs robust to missing observations
(Computational Statistics & Data Analysis, 2017-09-01) [Artigo]
Compound optimum design criteria which allow pure error degrees of freedom may produce designs that break down when even a single run is missing, if the number of experimental units is small. The inclusion, in the compound ...
Analysis of fractional-order models for hepatitis B
(Computational and Applied Mathematics, 2018-09-01) [Artigo]
This paper presents two models for hepatitis B, both given by fractional differential equations. The first model is formulated without parameters that indicate drug therapy, while the second one considers the drug therapy. ...
