This paper presents the integrated application of near and mid-infrared imaging techniques for the characterization of the wooden altarpiece preserved inside Santa Maria in Cosmedin Basilica (Rome, Italy). The visible part of this polychrome artefact is the result also of several changes applied during the centuries. The stratigraphic analysis of the artwork has been carried out by the use of pulsed thermography and reflectographic techniques in order to detect structural elements, such as defects on the support, and to disclose underlying graphical/pictorial features, such as underdrawings...

The use of projected fringes for the measurement of surface profile is a well-developed technique. In this paper, we present a surface profile measurement method for micro-components based on the combination of digital fringe projection, phase stepping, temporal phase unwrapping, and digital image acquisition. In this paper, a cost-effective machine is proposed. In particular, the paper describes the hardware and software realization. A simple procedure is described, which enables calibration of the optical set-up for subsequent quantitative measurement of micro-components of unknown shapes....

Growing interest is now addressed to using essential oils (EOs) as antimicrobial substances, in medical, industrial, food, and many other sectors. Oregano and thyme EOs are among the most effective oils and, for this reason, they have also been investigated in the field of cultural heritage. This work reports some preliminary results of a new approach for monitoring in-situ the biocide action on biological patinas by a fast analysis based on bioluminescence. In this research, we evaluated the efficacy of a commercial biocide based on EOs, in comparison with common commercial biocides...

We tackle the issue of measuring and analyzing the visitors dynamics in crowded museums. We propose an IoT-based system – supported by artificial intelligence models – to reconstruct the visitors trajectories throughout the museum spaces. Thanks to this tool, we are able to gather wide ensembles of visitors trajectories, allowing useful insights for the facility management and the preservation of the art pieces. Our contribution comes with one successful use case: the Galleria Borghese in Rome, Italy. Keywords. Pedestrian behaviour, floor usage, data acquisition, bluetooth, BLE, museums.

Each type of architecture (associated with both cubature architecture and landscape architecture) has its unambiguous dimension in the landscape. It is determined by the scale in which it occurs. The article is a kind of attempt to open a discussion on the role of intuitive metrology in landscape archeology. It should be taken into account that the measurement methods will sometimes fail and will not give the same conclusions as those resulting from human perceptual impressions. Therefore, let us note that the landscape refers to a diverse environment. It has not only a material layer, but...

In the project ARCHEO 3.0 a Machine Learning (ML) system for automatic contouring of the stratigraphic units of an archaeological excavation has been experimented. In this research, we have applied the same ML algorithm to aerial color photographs that represent very important tools in the study of ancient topography and landscape archaeology. Aerials of the Vulci necropolis, one of the most important cities of ancient Etruria, have been used. These photos, both vertical and oblique, have been chosen because the marks had been studied and analyzed in a recent PhD work in Ancient Topography....

This paper presents the study of a new generation textile temperature sensor, in two different heated ovens. The first chamber was used to evaluate temperature and the last one for the evaluation of both temperature and humidity. An acquisition system of LabVIEW and another one of Agilent were developed, involving even thermocouples and Pt100. The results show many metrological characteristics proving that the sensor is an RTD type. Index terms─Metrological, RTD, temperature sensor, textile industry.

This study is a collaboration between the, Eforia Extraurban of Thessaloniki and the departments of Sciences of the Cultural Heritage of the University of Salerno. The paper describes the survey of Tomb II of Agios Athanasios, Thessaloniki, carried out with the technique of the uncalibrated terrestrial photogrammetry. The final purpose is the realization of a georeferenced digital model. The results show that the acquisition techniques, although characterized by further margins of error, show the advantage of acquisition s speed and secure overlap between the frames, allowing to monitor the...

The research presented in this paper focused on the preliminary non-destructive analysis of copper alloys, corrosion, and soil components from a Roman archaeological site in Israel. pXRF, XRD, and micromorphological analyses were carried out to gain a better understanding of the corrosion processes affecting the copper alloy artefacts, by characterising the alloy composition, soil environments, and corrosion products. Preliminary results indicate that the artefacts consist of copper-lead-tin alloys, covered by copper hydroxy-chlorides and lead sulphate phases with slight variations in their...

Characterization of archaeological finds is a challenging case study for researchers, as the need of non-invasive measurements strongly affects the investigation strategies. Moreover, it is almost not possible to follow a fixed protocol, because the measurement conditions should be tailored to the samples under study. This paper presents a preliminary characterization of bronze coins coming from an archaeological site located in the south of Israel. The superficial corrosion layers have been analysed by means of Raman spectroscopy in order to investigate their composition and assess the...
