Uncertainty management in the measurements for the electric power quality analysis

2014

The paper deals with the uncertainty estimation in the measurements performed to assess the electric power quality. In a first steps, all the error sources, which give a significant contribution to the combined uncertainty associated to the measurement results, are identified. Successively, in order to analyze how the errors combine and propagate through the measurement chain, four approaches are proposed and validated. These approaches entail a greater and greater uncertainty overestimation, but, at the same time, require less and less time and resources. Therefore, the four methodologies are perfectly adequate for the implementation of the PUMA (Procedure for Uncertainty Management) metho…

Les exilés et l'enseignement de l'espagnol en France

2006

International audience; Au moment où la France accorde l’asile au demi million d’Espagnols qui fuient Franco, la langue espagnole n’intéressait qu’une minorité restreinte d’élèves. Au début des années cinquante, alors que l’anglais et même l’allemand connaissaient les faveurs accrues de la jeunesse, l’espagnol continuait de végéter au sein d’un système éducatif où rien n’était entrepris pour le rendre plus attractif. Au cours des années qui suivirent, l’arrivée au lycée des enfants des exilés républicains, et d’une façon plus localisée, le souvenir du rôle joué par les républicains-résistants dans la libération des certaines villes du sud, modifièrent sensiblement cette situation. Les desce…

Generation of stimulus features for analysis of FMRI during natural auditory experiences

2014

In contrast to block and event-related designs for fMRI experiments, it becomes much more difficult to extract events of interest in the complex continuous stimulus for finding corresponding blood-oxygen-level dependent (BOLD) responses. Recently, in a free music listening fMRI experiment, acoustic features of the naturalistic music stimulus were first extracted, and then principal component analysis (PCA) was applied to select the features of interest acting as the stimulus sequences. For feature generation, kernel PCA has shown its superiority over PCA in various applications, since it can implicitly exploit nonlinear relationship among features and such relationship seems to exist genera…

Strategie microbiologiche per la produzione di vini base ad elevata acidità da racemi della cultivar Grillo per l’ottenimento di spumanti siciliani

Sempre maggiore è l’importanza che stanno acquisendo gli spumanti Italiani nel mondo, ed anche la produzione vitivinicola in Sicilia è aumentata nell’ultimo decennio. Gli spumanti di qualità, però, sono caratterizzati da un’elevata acidità che non sempre è raggiunta nei vini base e negli spumanti prodotti nelle aree con climi caldo-temperati come quello siciliano. A tale scopo, si sono svolte delle fermentazioni su un mosto di racemi di Grillo, per l’ottenimento del vino di base spumante, avviando numerose attività di natura microbiologica, molecolare, chimico-fisica e sensoriale. I lieviti utilizzati come starter nelle fermentazioni, sono stati isolati da uve racemi raccolte nelle vendemmi…

LESD 260.panta 3.punkta piemērošana Eiropas Komisijas un Eiropas Savienības Tiesas praksē

2020

Viena no Eiropas Komisijas funkcijām un pienākumiem ir sekot, lai Eiropas Savienības tiesību akti tiktu pareizi un laicīgi piemēroti (t.sk. arī transponēti). Gadījumā, ja kāda Eiropas Savienības dalībvalsts noteiktajā termiņā nav ieviesusi pareizi vai pilnībā kādu Eiropas Savienības tiesību aktu, tad Eiropas Komisija var uzsākt pārkāpuma procedūru pret attiecīgo dalībvalsti. Darba autors analizē tieši LESD 260.panta 3.punkta tvērumu. Tāpat darba autors apskata LESD 260.panta 3.punktā nostiprinātos sankciju mehānismus, lai noskaidrotu, kā tiek aprēķināta kavējuma nauda un sodanaudu. Izpētot šos aspektus, autors pievēršas Eiropas Komisijas un Eiropas Savienības Tiesas praksei, lai noskaidrotu…

Snowball ICA: A Model Order Free Independent Component Analysis Strategy for Functional Magnetic Resonance Imaging Data

2020

In independent component analysis (ICA), the selection of model order (i.e., number of components to be extracted) has crucial effects on functional magnetic resonance imaging (fMRI) brain network analysis. Model order selection (MOS) algorithms have been used to determine the number of estimated components. However, simulations show that even when the model order equals the number of simulated signal sources, traditional ICA algorithms may misestimate the spatial maps of the signal sources. In principle, increasing model order will consider more potential information in the estimation, and should therefore produce more accurate results. However, this strategy may not work for fMRI because …

La comunicazione a supporto delle aziende vitivinicole per la valorizzazione degli spumanti siciliani.

2010

Il trend positivo che si è registrato negli ultimi due anni in Italia, sia per la commercializzazione che per l’export degli spumanti rispetto agli champagne, può essere per i produttori siciliani di spumante un trampolino di lancio per far affermare le loro produzioni sul mercato. Il presente lavoro, che rientra all’interno di una più ampia ricerca sul mercato degli spumanti siciliani, si pone come obiettivo quello di conoscere quali potenzialità di sviluppo può avere questo prodotto che, se pur di nicchia, è presente sui mercati prevalentemente regionali, ma poco valorizzato dai produttori stessi. In questa indagine si vuole, pertanto, conoscere il ruolo che la comunicazione può avere com…

Preserving Cultural Landscapes in South Africa: UAV Mapping of a Bokoni Archaeological Complex

2021

During the second year of the project “A social and spatial investigation at the Moxomatsi village”- Joint Mobility Projects: New Technologies for Social Science, ISARP 2018-20 - the work team of the University of Salerno (Department of Civil Engineering and Department of Cultural Heritage Sciences) was engaged in South Africa for the documentation of the Bokoni Archaeological Complex. Located in the present province of Mpumalanga, the Bokoni was a pre-colonial South African society, the research will be mainly focused on the study of agricultural settlements characterized by areas where densely walled settlements with roughly circular homesteads linked by walled roads are interspersed amon…

The NUPR1/p73 axis contributes to sorafenib resistance in hepatocellular carcinoma

2021

The multikinase inhibitor sorafenib was the first drug approved by the FDA for treating patients with advanced hepatocellular carcinoma (HCC). However, sorafenib resistance remains a major challenge for improving the effectiveness of HCC treatment. Previously, we identified several genes modulated after sorafenib treatment of human HCC cells, including the stress-inducible nuclear protein 1 (NUPR1) gene. Multiple studies have shown that NUPR1 regulates autophagy, apoptosis, and chemoresistance. Here, we demonstrate that treatment of HCC cells with sorafenib resulted in the activation of autophagic flux. NUPR1 knock-down (KD) in HCC cells was associated with increased p62 expression, suggest…
