Indagine composizionale sulle pitture di due vasi di Centuripe

2019

Due vasi Centuripe a Palermo sono stati analizzati utilizzando XRF portatile complementare e FTIR a riflessione totale spettroscopie. Le analisi consentono di chiarire la tavolozza e la tecnica della decorazione (pittura a tempera con un legante organico), e mostrano la presenza di pigmenti sia antichi che moderni (a causa di qualche recente riverniciatura). Uno dei risultati più interessanti è stata l'identificazione di due fasi del solfato di calcio nello strato sottostante i dipinti: a causa delle condizioni che trasformano il gesso in bassanite, la presenza di il gesso o, in alternativa, la bassanite in ciascuna parte analizzata possono rappresentare un criterio per distinguere l'origin…

Les premiers fers pendant l'âge du Bronze en France. Données nouvelles

2022

If iron was used in Asia Minor from the 3rd millennium BC, it was not known in Western Europe until the 13th century BC. In France, its first appears towards the end of the Bronze Age, possibly during the 13th century BC (Bronze final I / Bz D). Iron has been subsequently documented, especially during the 9th century BC (Bronze final IIIb / Late Atlantic Bronze Age 3 / Bz B2-3). Metallurgic iron is known only during this last stage of Late Bronze Age. The inventory of objects found in France, drawn up in 1981 and revised in 2009 has not changed much, despite several recent studies. However renewed data, with new discoveries and some objects removed from the list, call for an updated overvie…

Memory degradation induced by attention in recurrent neural architectures

2022

This paper studies the memory mechanisms in recurrent neural architectures when attention models are included. Pure-attention models like Transformers are more and more popular as they tend to outperform models with recurrent connections in many different tasks. Our conjecture is that attention prevents the recurrent connections from transferring information properly between consecutive next steps. This conjecture is empirically tested using five different models, namely, a model without attention, a standard Loung attention model, a standard Bahdanau attention model, and our proposal to add attention to the inputs in order to fill the gap between recurrent and parallel architectures (for b…

Detection of Duplicated Regions in Tampered Digital Images by Bit-Plane Analysis

2009

In this paper we present a new method for searching duplicated areas in a digital image. The goal is to detect if an image has been tampered by a copy-move process. Our method works within a convenient domain. The image to be analyzed is decomposed in its bit-plane representation. Then, for each bitplane, block of bits are encoded with an ASCII code, and a sequence of strings is analyzed rather than the original bit-plane. The sequence is lexicographically sorted and similar groups of bits are extracted as candidate areas, and passed to the following plane to be processed. Output of the last planes indicates if, and where, the image has been altered.

Haavoittuvuuksien torjunta defensiivisillä ohjelmointikeinoilla PHP-sovelluksissa

2012

Tutkielmassa kartoitetaan, kuinka SQL-injektioita, Cross-Site Scripting -hyökkäyksiä ja Cross-Site Request Forgery -hyökkäyksiä voidaan ehkäistä PHP-sovelluksissa defensiivisillä ohjelmointimenetelmillä. This thesis explores the defensive programming techniques for preventing SQL injections, Cross-Site Scripting attacks and Cross-Site Request Forgery attacks in PHP applications.

Old controversies and new data: assessing again the polychrome vases from Centuripe

2022

The necropolises of the hill town of Centuripe (EN) in Sicily have been looted since the nineteenth century for obtaining objects that were attractive for antiquities collectors, such as Hellenistic terracotta figurines and the brightly polychrome vases produced by local artisans (known as “Centuripe vases”) that today are scattered throughout a number of museums and private collections over the world. Until recent times, quite many vases have been considered doubtful and sometimes revealed as forgeries. Some “restorers” working in the dark circuit were able either to reproduce the shapes and decorations of ancient vases or to “refresh” their painted surfaces indeed: the interplay between g…

Dealing with a Trauma Burdened Past: between Remembering and Forgetting

2017

Recognition that societies will not be able to build a future as long as they do not face the ‘demons of the past’ has become a kind of universal truth over the last decades of the 20th Century (Gibney et al., 2008, p. 1). This view, though challenging and ambiguous, is reflected in the globally present attempts to improve or rebuild relations within and between different communities at the domestic and international level. The question concerning, on the one hand, the essence and most essential elements and, on the other hand, the instruments and the limitations of rebuilding relations, as well as the political implications of those processes have become the broad area of interest and the …

The Influence of Infection and Colonization on Outcomes in Inpatients With COVID-19 : Are We Forgetting Something?

2021

The COVID-19 epidemic has been a great challenge to health systems and especially hospitals. A prospective observational epidemiological study was planned as of February 26, 2020 in a tertiary hospital in the Valencia region. The total number of patients followed up with complete information during the first year was 2,448. Among other variables, the comorbidities of the patients were collected (and grouped in the Charson index), the stay in the intensive care unit (ICU), the co-infections, and the colonizations. Data on nosocomial infections due to said virus were also collected. The median days from the onset of symptoms to diagnosis were 4 + 4.6, while an additional 4.4 days had to pass …

Forgetful Audiences in Julius Caesar

2012

On note dans Jules César une récurrence d'épisodes où la mémoire du spectateur défaille, quand des personnages oublient une scène à laquelle ils viennent d'assister ou la retiennent de façon approximative. Cet article s'intéresse aux manifestations dramatiques et méta-théâtrales de ce phénomène, et avance que ces scènes d'oubli sont pour l'auteur le moyen de démontrer le caractère fuyant de la mémoire empirique et de proposer que le théâtre, plutôt que la salle de classe, constitue un terrain propice à l'exercice de cette mémoire. Julius Caesar exhibits a pattern of audience forgetfulness, when characters forget scenes they have just witnessed, or when they remember them imperfectly. This p…
