Interfacce della memoria : social media e patrimoni documentali online
No full textIl volume presenta i risultati del Progetto di Rilevante Interesse Nazionale TRAME, Tecnologie e Ambienti di Rete per la Memoria del XXI Secolo, coordinato da Mario Ricciardi. Il progetto ha affrontato il tema dell'integrazione tra gli ambienti di rete. Sono analizzati gli ambienti caratterizzati da una partecipazione forte da parte degli utenti nella fruizione collaborativa dei patrimoni digitali delle istituzioni che conservano la memoria culturale. L'approccio mediologico, le competenze e i nuovi sviluppi delle discipline documentarie, e la ricerca informatica interagiscono intorno alla prospettiva comune di un nuovo disegno di ambienti in rete per le istituzioni e le fondazioni che operano nel settore della memoria. Il saggio introduttivo COOPERARE COLLABORARE CONDIVIDERE di Mario Ricciardi (p. 3-21) affronta le problematiche della memoria digitale e della sua comunicazione nei nuovi ambienti di rete, approfondendo il rapporto tra documentazione analogica e digitale e tra le nuove opportunità offerte all'utente dagli ambienti di rete e la natura dinamica della memoria digital

The capacitated transshipment location problem with stochastic handling utilities at the facilities
No full textThe problem consists in finding a transshipment facilities location that maximizes the total net utility when the handling utilities at the facilities are stochastic variables, under supply, demand, and lower and upper capacity constraints. The total net utility is given by the expected total shipping utility minus the total fixed cost of the located facilities. Shipping utilities are given by a deterministic utility for shipping freight from origins to destinations via transshipment facilities plus a stochastic handling utility at the facilities, whose probability distribution is unknown. After giving the stochastic model, by means of some results of the extreme values theory, the probability distribution of the maximum stochastic utilities is derived and the expected value of the optimum of the stochastic model is found. An efficient heuristics for solving real-life instances is also given. Computational results show a very good performance of the proposed methods both in terms of accuracy and efficienc
Use of unsupervised and supervised artificial neural networks for the identification of lactic acid bacteria on the basis of SDS-PAGE patterns of whole cell proteins
No full textConventional multivariate statistical techniques (hierarchical cluster analysis, linear discriminant analysis) and unsupervised (Kohonen Self Organizing Map) and supervised (Bayesian network) artificial neural networks were compared for as tools for the classification and identification of 352 SDS-PAGE patterns of whole cell proteins of lactic acid bacteria belonging to 22 species of the genera Lactobacillus, Leuconostoc, Enterococcus, Lactococcus and Streptococcus including 47 reference strains.
Electrophoretic data were pre-treated using the logistic weighting function described by Piraino et al. [Piraino, P., Ricciardi, A., Lanorte, M. T., Malkhazova, I., Parente, E., 2002. A new procedure for data reduction in electrophoretic fingerprints of whole-cell proteins. Biotechnol. Lett. 24, 1477-1482]. Hierarchical cluster analysis provided a satisfactory classification of the patterns but was unable to discriminate some species (Leuconostoc, Lb. sakei/Lb. curvatus, Lb. acidophilus/Lb. helveticus, Lb. plantarum/Lb. paraplantarum, Lc. lactis/Lc. raffinolactis). A 7 × 7 Kohonen self-organizing map (KSOM), trained with the patterns of the reference strains, provided a satisfactory classification of the patterns and was able to discriminate more species than hierarchical cluster analysis. The map was used in predictive mode to identify unknown strains and provided results which in 85.5% of cases matched the classification obtained by hierarchical cluster analysis. Two supervised tools, linear discriminant analysis and a 23:5:2 Bayesian network were proven to be highly effective in the discrimination of SDS-PAGE patterns of Lc. lactis from those of other species. We conclude that data reduction by logistic weighting coupled to traditional multivariate statistical analysis or artificial neural networks provide an effective tool for the classification and identification of lactic acid bacteria on the basis of SDS-PAGE patterns of whole cell proteins
