An execution in medieval Sicily: Computerised tomography scan analysis and 3D reconstruction of an ancient forensic context
2019
The bioarchaeological and forensic approach is increasingly applied in the study of funerary contexts in archaeology. Here, we present a case of an atypical medieval burial recently discovered in Piazza Armerina (Sicily), in which the integrated use of traditional bioarchaeological and forensic anthropology methods was crucial. The skeleton was lying in a prone position and was characterised by a peculiar injury pattern. We recorded six clear stab wound marks on the posterior surface of the sternum. The use of computerised tomography scan and 3D modelling techniques has made it possible to obtain a reliable reconstruction of the cause and modality of death, pointing to the execution of the …
Increasing contextual information by merging existing archaeological data with state of the art laser scanning in the prehistoric funerary deposit of…
2013
Abstract In this paper we present a virtual reconstruction of prehistoric funerary practices in Pastora Cave, a collective burial site in Eastern Spain that dates from the Late Neolithic, Chalcolithic and Bronze Age. Modern data of the cave was captured by 3D laser scanning techniques and added to recorded archaeological data and 3D graphic information. The combination of these data sets allowed us to create a hypothetical reconstruction to analyze the material excavated in the 1940s and 50s in greater spatial context. A 3D model of the current cave was created in order to serve as a basis for modeling the relative stratigraphic information available. We present the methodology employed and…
The virtual reconstruction of the minaret of Mansourah mosque (Algeria)
2015
This contribution synthetically addresses some of the photogrammetric solutions available today in the field of architectural-archaeological survey and the related applications outcome, evaluated during both the acquisition phase of metric data than in those of effective yield of refunds infographics. Therefore, we have focused on the virtual reconstruction of one of the most emblematic and symbolic building of the Algerian culture, the mosque of Mansourah, returning the minaret as it appeared before its partial collapse, namely correspondent in geometry, textures, and colours. The work is part of a larger research project to promote knowledge and dissemination of Algeria cultural heritage,…
Acciones para mejorar la eficiencia energética en los edificios en Europa: estado del arte sobre los standards técnicos
2022
The paper is aimed at reviewing the state of the art of the European technical normative implementation during the last decades concerning the building energy efficiency. Indeed, it is well acknowledged that the present building stock is largely obsolete and inefficient: in the European context alone, around 75% of the buildings is not energy efficient and most are expected to be in use until 2050. Consequently, buildings require not only a general rehabilitation, to extend, or even avoid, its end-of-life time, but also a complete afterthought of their energy performance. That is extremely urgent to improve the overall sustainability of the construction sector that, alone, is one of the mai…
The shaping of public economic discourse in postwar America: the 1947 meat shortage and Franco Modigliani's meat plan
2015
This paper discusses the American debate over price controls and economic stabilization after World War II, when the transition from a war economy to a peace economy was characterized by bottlenecks in the productive system and shortages of food and other basic consumer goods, directly affecting the living standard of the population, the public opinion, and political discourse. Specifically, we will focus on the economist Franco Modigliani and his proposal for a "Plan to meet the problem of rising meat and other food prices without bureaucratic controls." The plan prepared by Modigliani in October 1947 was based on a system of taxes and subsidies to foster a proper distribution of disposabl…
Reconstruction of inclined air showers detected with the Pierre Auger Observatory
2014
We describe the method devised to reconstruct inclined cosmic-ray air showers with zenith angles greater than $60^\circ$ detected with the surface array of the Pierre Auger Observatory. The measured signals at the ground level are fitted to muon density distributions predicted with atmospheric cascade models to obtain the relative shower size as an overall normalization parameter. The method is evaluated using simulated showers to test its performance. The energy of the cosmic rays is calibrated using a sub-sample of events reconstructed with both the fluorescence and surface array techniques. The reconstruction method described here provides the basis of complementary analyses including an…
Techniques and procedures for the definition of AR applications in architectural and archaeological contexts
2022
The growth and development of Augmented reality applications and their use in different contexts has been recently fostered by two factors: i) the hardware and computing power of mobile devices has been radically improved; ii) Apple and Google have released two development platforms for AR applications. AR has been a major topic in research on cultural heritage fruition for many years, but the latest developments are really promising, and they seem capable of overcoming the difficulties that have delayed the diffusion of this technology. The paper focuses the potential and criticalities of augmented reality systems used for fruition purposes in architectural and archaeological contexts. The…
Per un teatro dell'architettura e della città: teorie e pratiche di realtà aumentata alla Cité de l'architecture et du patrimoine al Palais de Chaill…
2017
Lo studio presenta gli esiti di una ricerca volta allo sviluppo di un allestimento museale con sole tecniche di realtà aumentata per la Cité de l’architecture et du patrimoine (Palais de Chaillot, Parigi). Realizzato sfruttando la recentissima piattaforma Google Tango, questo sistema permette al visitatore di accedere a contenuti multimediali e visualizzare ricostruzioni digitali 3D, appositamente elaborate, semplicemente inquadrando con uno smartphone Tango-enabled i calchi e i plastici esposti nel museo. This study presents the results of a research which aims to develop a museum exhibition planning, with interactive augmented reality techniques, at the Cité de l’architecture et du patrim…

Mathematical Methods in Image Processing and Computer Vision
2016
Image processing and computer vision are growing research fields that take advantage of the increasing power or modern computers linked with sophisticated techniques coming from many fields of expertise and in particular from mathematics. We present an introduction to some problems in computer vision and image processing and to some mathematical techniques and concepts that are nowadays routinely used to approach them.
