THE SITE OF SAN CALOCERO DI ALBENGA (SV). AN INTER-DISCIPLINARY METHODOLOGICAL TRAINING GROUND

This paper summarizes the results of the research on the site of San Calocero di Albenga where, in late antiquity, a martyrial sanctuary was built on the remains of a probable funerary enclosure of the late imperial era. This site is known since the first half of the twentieth century for the pioneering research of Nino Lamboglia both in the field of the first experiences of stratigraphic archaeology and for an embryonic reading of the walls. After further investigations by the Soprintendenza della Liguria, the archaeological complex has been the subject of new studies since 2014. At this moment, the Politecnico di Milano was involved in surveying activities, and extensive use of archaeometric investigations was made. In particular, the minero-petrographic analysis of the mortars and the C14 on the lime clumps allowed reaching new significant knowledge in the scanning of construction activities and their dating

Diachronic and Synchronic Analysis for Knowledge Creation: Architectural Representation Geared to XR Building Archaeology (Claudius-Anio Novus Aqueduct in Tor Fiscale, the Appia Antica Archaeological Park)

This study summarises research progress to identify appropriate quality methodologies for representing, interpreting, and modelling complex contexts such as the Claudian Aqueduct in the Appian Way Archaeological Park. The goal is to intrinsically integrate (embed) geometric survey (Laser scanning and photogrammetric) with the materials and construction techniques (Stratigraphic Units-SU), semantic models in order to support the design with a better understanding of the artefact considered, and also to give indications that can be implemented in the future in a continuous cognitive process. Volume stratigraphic units in the form of architectural drawings, heritage building information modelling (HBIM) and extended reality (XR) environments have been oriented to comparative analyses based on the research case study's complex morphology. Analysis of geometries' intersection, construction techniques and materials open up new cognitive scenarios, self-feeding a progressive knowledge and making different studies correlatable, avoiding diaspora or incommunicability. Finally, an extended reality (XR) platform aims to enhance tangible and intangible values through new human-computer interaction and information sharing levels

Study of the pigments in medieval polychrome architectural elements of Veneto-Byzantine style

Abstract An analysis of pigment traces obtained from an ensemble of marble and limestone finely sculpted architectural elements, kept in the National Archaeological Museum of Cividale del Friuli (Italy), has been performed using scanning electron microscopy (SEM), particle induced X-ray emission (PIXE) and, for the white paint, Raman spectroscopy (RS). The experimental results on six different colours, combined with the historic, stylistic and documentary evidences provided by a recent study, strengthen the hypothesis of the dating and the provenance of all the sculptures in a prestigious building of Cividale in Veneto-Byzantine style, the palace of the Patriarch of Aquileia. The analyses also allow a first insight into the conservation history of the ensemble of architectural decorations

Interactive and Immersive Digital Representation for Virtual Museum: VR and AR for Semantic Enrichment of Museo Nazionale Romano, Antiquarium di Lucrezia Romana and Antiquarium di Villa Dei Quintili

The research focuses on the generation of 3D models aimed at creating interactive virtual environments as the outcomes of scalar representations of existing realities. The purpose is to increase the narration, fruition, and dissemination of the findings that emerged from the archaeological investigations carried out in a large sector of the south-eastern suburbs of Rome. In this context, the research proposes a process oriented toward designing a virtual museum of the first group of works from the Appia Antica Archaeological Park and now exhibited at the Museo Nazionale Romano, the Antiquarium di Lucrezia Romana, and the Antiquarium di Villa Dei Quintili. Managing high historical and cultural findings through geometrical surveys, high-resolution data from 3D survey analysis, archival research, and interactive digital representation is the aim of the study. The digitisation of artefacts has made it possible to build new forms of communication that enrich virtual and on-site visits with content, both of the park and of the Museums that host the collections. In particular, it has gradually allowed a 'virtual' relocation of works from the Appia Park, favouring the definition of a method capable of communicating new content and laying the basis for the development of a virtual museum, a temporary exhibition, and a web platform for one of the most important historical sites of ancient Rome

La defunzionalizzazione e l'abbandono dell'anfiteatro di Albenga nel quadro di una citt\ue0 in trasformazione

Optical-Based COTS Data Communication Bus for Satellites

Commercial Off The Shelf (COTS) components are gathering more and more interest from satellite developers thanks to their lower cost and ease of procurement as compared to space qualified ones. A number of studies to evaluate the possibility of COTS use in space systems are under way: they get benefits from the fast evolution of automotive and consumer electronic devices, which makes available innovative solutions and more reliable systems. This paper focuses on the analysis of the IrDA (Infrared Data Association) protocol and and discusses the use of this standard to exchange data between the sub-systems of a satellite. This technique has many advantages towards other data interfaces such as CAN or proprietary solutions for low bit rate links, since it reduces the amount of wiring, keeping the benefits of standard and well documented solutions. We also analyze cosmic radiation effects and propose an implementation which makes use of commercial low cost components
