Cultural Heritage studies often require to perform analyses on buildings which have undergone several changes and alterations during their lifetime. This often implies loss of architectural elements or construction of new elements, in turn disrupting the perception of the former buildings. The recovery of lost elements or structures through virtual reconstructions is of paramount importance in both scientific and cultural applications. In this case, novel procedures in surveying and photogrammetric processing offer a powerful tool, allowing to extract geometric information from historical...

The contribution shows some results of a multidisciplinary research in which architectural surveying and representation methods are supported by archival documents analysis. The procedure is applied in a limited area of the ancient walls of Cagliari (Sardinia, Italy). The sector consists in the meet point between the sixteenth century bastion called Curtain of Santa Chiara realized in the period 1575-1578 by the military engineer Giorgio Paleari and the curtain of de Cardona commissioned by the Viceroy in the 30s of the same century. The historical documents indicates the presence of...

Surveys performed in the aftermath of recent earthquakes have shown that the structural and anti-seismic performances of masonry buildings are related not only to structural damages and masonry quality but also other key features such as effectiveness of connections, damages of wooden elements or criticalities related with humidity. To this aim technical and scientific communities are interested in development or improve existing procedures for the fast-visual survey and diagnostics in order to measure and analyze all the parameters affecting the building performance. In this paper a new...

Characteristic of Alpine settlements is the low percentage of pottery probably for the use of wooden bowls. The study of the Orgères ceramic findings represents the first sampling on the clays which will be the starting point for the archeology of the Valle d Aosta.

The intrinsic complexity of the coating systems on historical bowed string musical instruments complicates the characterization of the different materials that have been subsequently spread on the wood. Even more challenging is the identification of their spatial distribution in the sequence of the finishing layers. To face both issues, in this study we combined Synchrotron radiation micro - FTIR in reflection geometry and Chemometrics for the investigation of five micro-samples mounted in crosssections, removed from musical instruments made by Antonio Stradivari, Francesco Ruggeri and...

A prototype X-ray fluorescence (XRF) scanner was developed with the aim of being reliable and portable, best suiting the needs of cultural heritage scientists who constantly face the difficulty of in-situ analysis. The instrument constructed is composed of an exchangeable scanning head (X-ray tube and detector), a motorized x-y stage with a controlling interface and a laptop. With the small stage, it can scan areas up to 20 x 20 cm2 with a lateral resolution of 1 mm. The system can be transported inside a standard airplane cabin trolley and weights no more than 10 Kg. The controlling...

This article deals with the creation of a professional magnetometer, a flexible, light and compact instrument that can be installed on aerial and marine drones. The instrument can accurately measure the local magnetic field. Subsequently, it was installed on AUV and a micro ROV to test its effectiveness for archaeological purposes and magnetic surveys. Experimental data show that both systems can be used by filtering disturbances from vehicles.

Non-destructive surveys were carried out in the cave churches of Matera. Aim of surveys was to understand the conservation degree of the frescoes conserved in the churches. The investigations highlighted the presence of many structural problems related to fractures and wet.

In this contribution we will focus on some results achieved within the international bilateral project Non-invasive investigations to enhance the knowledge and the enjoyment of cultural heritage (funded by the Italian National Research Council and by the University of Malta). In particular, we will focus on some GPR and geoelectrical investigations performed on the so called Red Tower and on the so called White Tower, both on the western side of the island of Malta.

Radiocarbon dating was used on mortars exploiting the C uptake during the carbonation process, where the atmospheric CO2 signal is absorbed by reaction with lime putty, and then it is converted back into CaCO3-binder containing the signature of the construction time. The CaCO3-binder must be isolated from other carbonate sources and contaminants such as delayed hydraulic and secondary alteration products which could affect the dating process [1]–[3]. An appropriate mineralogical characterization of the mortar greatly enhances the understanding of the reaction history of the material allowing...
