No full textAnalysis and modelling of rainfall fields at different resolutions in southern Italy
No full textThe spatial and temporal variability of the scaling properties and correlation structure of a data set of rainfall time series, aggregated over different temporal resolutions, and observed in 70 raingauges across the Basilicata and Calabria regions of southern Italy, is investigated. Two types of random cascade model, namely canonical and microcanonical models, were used for each raingauge and selected season. For both models, different hypotheses concerning dependency of parameters on time scale and rainfall height can be adopted. In particular, a new approach is proposed which consists of several combinations of models with a different scale dependence of parameters for different temporal resolutions. The goal is to improve the modelling of the main features of rainfall time series, especially for cases where the variability of rainfall changes irregularly with temporal aggregation. The results obtained with the new methodology showed good agreement with the observed data, in particular, for the summer months. In fact, during this season, rainfall heights aggregated at fine temporal resolutions (from 5 to 20 min) are more similar (relative to the winter season) to the values cumulated on 1 or 3 h (due to convective phenomena) and, consequently, the process of rainfall breakdown is nearly stationary for a range of finer temporal resolutions. © 2014 © 2014 IAHS Press
L'entreprise de Giotto
No full textThe comparative study of several big wooden crosses painted by Giotto allowed to deepen the work organization in the Middle Ages’ workshop. This analysis found several analogies of execution between the works, by demonstrating that the production of these masterpieces was subordinated to certain codified rules, pre-established by the workshop’s master, a really skilful business manager of the Middle Ages.L’étude comparative des grandes croix de bois peintes par Giotto a permis d’approfondir l’organisation du travail dans l’atelier du Moyen-âge. Cette analyse a relevé de nombreuses analogies d’exécution entre les œuvres, en démontrant que la production de ces chefs-d’œuvre était subordonnée à certaines règles codifiées et préétablies par le maître d’atelier, habile chef d’entreprise du Moyen -âge
