Ground Penetrating Radar investigation of the floor of Palazzo Vecchio s Great Hall

Ground Penetrating Radar is a powerful nondestructive investigation tool widely used in archaeology. This paper reports the radar investigation of the floor of Palazzo Vecchio s Great Hall. In 1555 Cosimo I dei Medici commissioned a monumental fountain that should be collocated in the Great Hall, but the historical sources state that it was never installed in its own collocation. The aim of this radar investigation is to find traces (e.g. a basement or water pipes) under the floor that could support the hypothesis of a temporary collocation of the fountain in the Great Hall. Although the...

Diagnostic of historical vehicle s engines by acoustic emission techniques

The reactivation of artefacts mechanisms is always a challenge for conservators and proper noninvasive diagnostic techniques, applicable directly on the artifacts, allows to perform a precocious diagnostic and to avoid damages. The ACUME_HV project (Acoustic Emission Monitoring of Historical Vehicles) represents the first use of acoustic emission (AE) as non-invasive technique for the diagnostic of historical vehicles. The aim of this project is to propose an objective, human-independent method that will help the personnel of the museums to take decisions concerning the reactivation of the...

New, non-invasive texture measurement method for archaeology

During the preparation of metal objects, the technological processes like casting, plastic deformation and heat treatments evolve characteristic crystallographic fingerprint called texture, in the microstructure of metals. This texture remains unchanged for centuries. So, the characterization of texture is a conclusive explanation regarding the former process or processes. A new, non-invasive texture measurement method was developed for centreless X-ray diffractometers. By using this method, the most widespread texture visualization the pol figures can be realized. The paper introduces the...

Archaeological application of centreless X-ray diffractometers for non-destructive pole figure measurements

Based on the crystallographic texture, the parameters of metal forming, heat treatment of metallic objects can be very well reconstructed as far as conventional technology (eg rolling, deep drawing, etc.) was applied. The characterization of the texture, except for the neutron diffraction, has been possible only by the destructive method. We have developed and validated the non-destructive texture measurement method for centreless diffractometers. The diffractometers, by their function, allow nondestructive testing, thus providing a whole new dimension for the examination of archaic objects....

Structural health monitoring of the Ninfeo Ponari by combined use of fibre optic sensors, photogrammetry and laser scanning

The Ninfeo Ponari is an ancient building dating back to the first century BC, located in the ancient Roman city of Casinum. The building is one of the best preserved examples of coenatio aestiva, a leisure annex of a rich domus. It consists of two bodies: a rectangular room covered by a barrel vault and an atrium with no roof and a shallow pool in centre. The structural condition of the building is not critical but its preservation is at risk: it is located on a hill slope where some extended sliding activity is present; it is not protected by an efficient rainfall drainage system. Aim of...

Integration and modelling of 3D data as strategy for structural diagnosis in Endangered Sites. The study case of Church of the Annunciation in Pokcha (Russia)

Cultural Heritage and its variety of Built Heritage is increasing a scientific cognitive approach from European Committees, related to the difficulties of its protection and management. This is primarily due to the lack of emergency protocols of structural knowledge and documentation on architecture and ruins, for the protection and intervention on an Endangered Heritage that is going to disappear. The consideration of structural documentation applied to Historical Built Heritage, as in the case study of Pokcha Church (Russia), reviews the declination of integrated products of 3D survey into...

Roots of Parametric Thinking in Palladio s Villas. Surveying, interpreting and visual programming the plates from I quattro libri di architettura

In this work we want to link the considerations relating to the rectangular ratios and harmonic proportions of Palladio s plans, through the automation of the Shape Grammar rules rewritten here in Visual Programming Language. This operation allows to program generalized automatisms for the construction of some Palladian villas (e.g. Villa Thiene, Villa Sarego, Villa Poiana), cataloguing them in families mainly linked to the size of the tartan grid used (e.g. 5 x 3). This experimentation could show how algorithmic thought has distant roots, finding in the contemporary era a new digital life...

3D procedural modeling of complex vaulted systems: geometric rules vs SfM based modeling

Starting from the geometric genesis of simple and complex vaulted systems, the paper proposes a workflow developing an algorithmic model for the construction of 3D digital surface model of some vaulted systems. The writing of an algorithm allows us to obtain pavilion and cross vaults digital surface models. To test the effectiveness of the models obtained in the application of the algorithms to real case studies, the ongoing phase of the research involved the survey of some complex vaulted systems based on Light Detection And Raging (LiDAR) and Structure from Motion (SfM) techniques. The...

Digital Survey and 3D Geometric Interpretation of Complex Vaulted Systems. Palazzo Valperga Galleani di Barbaresco in Turin

The present contribution proposes the study of the a fascioni vaults, which derive from Guarini s experience, that characterized, between the seventeenth and eighteenth century, part of the baroque architectural production in Piedmont. Such unitary vaults are characterized by the subdivision, through twisted arches, of the intrados into regular fields, covered by secondary vaults. The case study presented, Palazzo Valperga Galleani di Barbaresco in Turin, aims to deepen, through 3D representation digital tools, the links between the realizations, the references to treatises and manuals and...

Thermoluminescence dating laboratory improvements tested on an archaeological rescue site in Trino, Vercelli province, Italy.

Thermoluminescence (TL) is a reliable radiation-based technique for the dating and authentication of ceramic objects, allowing the evaluation of the time elapsed since their last exposure to high temperatures (e.g. firing in kiln or later fire events). The TL laboratory developed in the last decade at the Physics Department of the University of Torino, currently operating within the INFN (National Institute of Nuclear Physics) CHNet network, is presented. The 10-years-long experience in the field resulted in the enhancement of the procedures, with the development of customised α and β...
