activated sludge model 2d calibration with full-scale wwtp data: comparing model parameter identifiability with influent and operational uncertainty.the present work developed a model for the description of a full-scale wastewater treatment plant (wwtp) (manresa, catalonia, spain) for further plant upgrades based on the systematic parameter calibration of the activated sludge model 2d (asm2d) using a methodology based on the fisher information matrix. the influent was characterized for the application of the asm2d and the confidence interval of the calibrated parameters was also assessed. no expert knowledge was necessary for model calibrati ...201424337821
opportunities and contradictions in maritime heritage and small-scale fishing--a case study of catalonia.much has been written in recent years about the crisis in fisheries caused by the critical reduction in catches and about the strategies developed by local communities of fishers in response. the aim of this article is to demonstrate that the use of maritime heritage can also be considered part of these strategies. like fishers elsewhere, catalan small-scale fishers face severe threats to their professional survival. recently some of them have became involved in activities related to maritime he ...201424851632
