Measurements for the reconstruction of ancient walls in opus reticulatum in the basement of the castle of Santo Stefano in Puglia (Italy)

One of the results of the study of the Castle of Santo Stefano in Monopoli, in Puglia (Italy) - aimed at its restoration - is the discovery of the different construction phases of the building. The investigation made use of different types of measurements which, intertwined with each other, determined a clear picture of the construction phases. This work presents the investigations carried out in the basement of the castle, which returned the morphotypological relief of the walls in opus reticulatum built between the second century BC. and the second century AD. It can be seen that the walls were reused in the late ancient and medieval ages. The data obtained from the experimental investigation were compared with other data such as the definition of the historicaltopographical framework, the archaeological investigation, the prospecting. In this study, direct and indirect measures proved crucial to highlight the construction phases of the building. The comparison between the basements and the upper church led to the determination of the causes of degradation.

Castiglioni Chapel in Pavia: a methodological approach for documentation and virtualisation techniques

In the reuse project of an environment, in order to define the set of residual services provided by the building organization as a whole, both spatial and material analyses of the current state need to be paired with a survey of both environmental and technological systems. In the case study of the Castiglioni Chapel, it is also essential to associate the various diagnostic outputs with the survey, in order to plan specific interventions for the site management project. The presented survey methodology targets the analysis of the alterations and evident cracks in the intrados of the vault. AR/VR systems allow to enhance the representation of the proposed reuse of the Chapel. All the aforementioned are aimed at devising a function that makes the space as a place of knowledge and digital use of the Chapel.

Space and sound characterisation of small-scale architectural heritage: an interdisciplinary, lightweight workflow.

This contribution reports on a data acquisition and processing chain the novelty of which is primarily to be found in a close integration of acoustic and visual/metric data. Its outputs pave the way for proportion-as-ratios analyses, as well as for the study of perception aspects from the acoustic point of view. Ultimately, perceptive data will be related to objective data such as acoustic descriptors or architectural metrics. The experiment is carried out on a set of fifteen small-scale rural chapels, which is a corpus intended at fostering cross-examinations and comparative analyses. The specificity of this corpus in terms of architectural layout, of use, and of economic and access constraints, will be shown to have had a significant impact on the technical and methodological choice made all along the acquisition and processing.

Preliminary studies on the volumetric capacity of ceramic from the Neolithic site of Lugo di Grezzana (VR) through 3D graphics software

The aim of the study is to obtain an estimate of the volumetric capacity from a selection of ceramic vessels from the Neolithic site of Lugo di Grezzana (Verona, Italy). The method applied involved the use of Blender, a free and open source 3D computer graphics software. This program can calculate the volume from the graphic elaboration of the archaeological drawing of the artifacts. Through the calculation of volume has been possible to obtain an estimation of the total capacity of the vessels, proposing two types of content. The volumetric estimates were later compared between diameter and height of each ceramic vessels, to define the size classes. The research shows that the internal variability of some ceramic shapes could be the consequence of different functional and/or cultural choices. This paper tests a method which could be applied in future research projects.

Multianalytical investigation and 3D Multiband modeling: an integrated survey of the Garnier Valletti pomological collection

Digital Close-Range Photogrammetry allows to acquire high-fidelity models useful to document Cultural Heritage with a high level of detail. This technique also has an analytical potential able to gain new knowledge about works of art and their state of preservation. This project carries out a diagnostic survey using 3D Multiband modeling, High Resolution Digital X-Radiography and Pulsed Thermography to document and evaluate from a conservative point of view the polymaterial exemplars of the Garnier Valletti pomological collection. The analytical integration of Imaging techniques and 3D modeling provides information from the superficial, sub-superficial and innermost layers of the object, respectively, capturing both accurate morphometric, spectral and density data. The paper presents the results obtained on the particular case study of polymaterial and multilayer artifacts for which Pulsed Thermography has proven to be a highly predictive technique from a conservative point of view.

Investigation of archaelogical sites with species distribution models and satellite data

The combined use of probability distribution models and remote sensing data can benefit the study of archaeological landscapes in the perspective of both archaeological risk impact assessment and scientific field surveys planning. A multiscale comparison between two predictive models a Geographical Information System (GIS) based multiparametric spatial analysis (MPSA) and the Maximum Entropy Model (MaxEnt) is presented. Both response (presence only) and independent variables included attributes derived by cartographic sources and satellite data. Best model selection (Akaike s Information Criterion) and Receiving Operator/Area Under the Curve analysis indicated a better performance of MaxEnt with respect to the GIS-MSPA model. Insights on pitfalls and potentials for the progress of this kind of approach in the archaeology operational context are described.

The use of Cone Penetration Tests (CPT) for the study of the dynamic characteristics of the soils

This paper describes and compares the results of in situ investigations performed on two Sicilian test sites: Augusta Saline (SR) and Catania STM M6 areas. The studies were carried out to determine the variation of shear modulus with depth by Cone Penetration Tests (CPT), Standard Penetration Tests (SPT), Down - Hole Tests (DHT), Seismic Dilatometer Marchetti Tests (SDMT). The available data also enabled one to compare the shear modulus profile obtained by empirical correlations based on CPT and SPT with Down - Hole Test and Seismic Dilatometer Marchetti Test.

Urban Archaeo-Geophysics in Cusco. The Case Studies of Paraninfo and Casa Concha

The detection of archaeological heritage buried in urban areas represents today one of the most complex challenges of the cultural heritage sciences. The inter and trans disciplinary integration of archeology and geophysics can provide a significant contribution to open new perspectives and approaches addressed at improving the knowledge of the history of cities and locate the areas to beprotected. The high complexity for the identification and interpretation of geophysical characteristics in the urban subsoil makes it necessary to develop ad hoc procedures to be implemented and validated in significant case studies. This work shows the results of an interdisciplinary project in Cusco (Peru), the capital of the Inca Empire, where the georadar method has been applied in urban areas of the city, in particular in courtyards of important historical palaces. This follows a published work on georadar based investigations of the main square of the city

A digital twin for distant visit of inaccessible contexts

This paper describes the example of an interesting distance visit approach carried out during the COVID-19 emergency, applied to an underground oil-mill in the town of Gallipoli (Puglia, Italy). The limitations of access for people with disabilities and the complete closure of Italian museums during the emergency have suggested the development of an immersive platform, in the broader perspective of using the output in according with digital twin perspectives. Then a tool to support an innovative visit method has been realized: a virtual visit assisted by a real remote guide, hereinafter referred to as Live-Guided Tour with e-learning functionality. All this has been made possible starting from a threedimensional model of an underground oil-mill, from which we extracted the stereoscopic scenes. The stereoscopy is very important for the overall success of the project, because this aspect influences the level of interest, the immersion and the ability to generate emotion and wonder. Probably this is the only system available today for a shared virtual visit for an inaccessible context, which implements many features of a VR visit in a multi-user and multi-platform environment.

An assessment on morphological survey calibration and the automation of digital drawing for the reliable documentation and conservation analysis of out-of-scale buildings

The application of digital survey practices on Built Heritage has to face in different cases with singular typologies of architectural systems that have an out-of-scale proportion (as tower bells, minarets, civil towers), facing also with uncommon phenomena of structural instability and decay, due to their specific geometry. Their study shows intrinsic instability systems related to their singular structural form, the unusual dimension and the low frequency of ordinary maintenance and restoration, which tend to increase throughout the lifecycle of the building and the exposition to agents of its construction materials. In this cases, the aim to monitor the conditions of conservation influences the methodological purposes and pipeline of survey, bridging the practices of rangebased and image-based survey through new standards of density, resolution and reliability of data necessary to assess the analysis of such type of monuments. A reflection on the quality of morphological databases to derive digital elaborations and maps for the analysis of instabilities and the monitoring of risks in out-of-scale buildings is presented.
