The determination of volumes and interface areas from confocal laser scanning microscopy (CLSM) images requires the identification of component objects by segmentation. An automated method for the determination of segmentation thresholds for CLSM imaging of biofilms was developed. The procedure, named objective threshold selection (OTS), is a(More)
A mathematical model was developed that can be used to describe an aerobic granular sludge reactor, fed with a defined influent, capable of simultaneously removing COD, nitrogen and phosphate in one sequencing batch reactor (SBR). The model described the experimental data from this complex system sufficiently. The effect of process parameters on the(More)
—Github has evolved from traditional version control systems to incorporate the wave of the Web 2.0. Intensive collaboration among developers is one of the main goals of Github beyond traditional version control. Understanding how those developers collaborate is a key issue to enhance the outcomes of individuals and of the ecosystem as a whole, as well.(More)
In this paper, we present the findings of a systematic review of the SRE literature, covering 300 papers in 95 publication venues (conferences and journals) in the last twelve years. We employ statistic techniques to help mining patterns and trends from the analyzed data set. We identified a prevalence of purely theoretical studies in the surveyed period,(More)
The mathematical modeling of spatial biofilm formation that provides the capability to predict biofilm structure from first principles has been in development for the past six years. However, a direct and quantitative link between model predictions and the experimentally observed structure formation still remains to be established. This work assesses the(More)
