High-resolution geophysical investigation at Banditaccia Necropolis (Cerveteri) by means GPR and magnetic surveys

In the search for bodies of archaeological interest at shallow depths, geophysical methods can provide useful indications. The aim of the present work, carried out in collaboration with the Archaeological Park of Cerveteri and Tarquinia, was to detect the presence of tombs/graves and/or buried structures in an unexplored area of Banditaccia Necropolis (Cerveteri and Tarquinia Archaeological Park), one of the largest ancient necropolis in the entire Mediterranean area. In the investigated area, two different non-destructive geophysical techniques have been employed: Ground-Penetrating Radar and gradiometry. The results made it possible to identify anomalies referable to probable structures of archaeological interest buried at a depth of several meters and probably attributable to tombs/graves.
These geophysical results will preparatory to set up an archaeological excavation.

From Space to Tree: multisensor and multiscale remote sensing based approach for monitoring monumental trees. The case of archaeological park of Colosseum in Rome. Preliminary results

The paper deals with a multi-scale, multi-sensor remote sensing approach, based on the integration of satellite data and proximal imaging sensing technologies with the aim to support the management of historical and archaeological parks with a focus on: analysing the health and changes in the tree; assessing the biomechanical stability of monumental trees; identifying critical issues at the vegetation-monument interface areas. The Colosseum Park in Rome is one of the scenarios-laboratories selected. The obtained results are the following: (i) the integration between the diverse sensors, in a multi-scalar perspective, combined with the knowledge of the end user s needs and application goals, leads to an improvement in the operability of the technologies; (ii) the minimum monitoring unit, using Sentinel 2, is the single tree; (iii) removing seasonality helps to better discriminate between healthy and diseased trees; (iv) the best period to identify the effects of Toumeyella parvicornis is Spring (May-June).

An innovative heuristic strategy for the management of buried scenarios with strong discontinuities

This contribute proposes a heuristic strategy for processing GPR data referred to scenarios characterized by strong buried discontinuities, for which the common assumption of a homogeneous soil drives to errors in the imaging. This can be the case of layered media or the case of electrically large buried cavities. Here, the focus is on the buried cavities and a combined time-depth conversion strategy, which is able to account for the different propagation velocities in the cavity and in the surrounding soil, is proposed. Results referred to simulated data provide a preliminary assessment of the achievable imaging capabilities.

An art-historical and scientific investigation into two Early Cinquecento Renaissance Polyptychs by Antonio de Saliba (1466/7 - c. 1535) on Sicily and Malta

The most recent discovery of six privately owned panel paintings potentially associated with Sicilian Renaissance artist Antonio de Saliba s (1466/7 – c. 1535) now dismembered 1515 titular altarpiece for the Franciscan Observant Church in Rabat, Malta, along with the two central panels of the same altarpiece that are found within the church, has made it possible to fill in gaps in art-historical research on Renaissance art in Malta. It also allows for comparisons with Antonio’s documented 1503-04 Taormina Polyptych at the Church of St Nicholas of Bari, simultaneously generating new interest in this work, particularly for its elaborate Late Gothic gilded framework. This paper aims to reconstruct the Rabat Polyptych’s framework digitally and hypothetically, using a similar approach to that employed for the digital reconstruction of the Taormina work. Additionally, the paper interprets and discusses the findings from various scientific analyses of the panels current state of preservation and pigment and wood composition in relation to the field of conservation of cultural heritage.

Broadband vibroacoustic fingerprint of a historic building chamber concert room in Napoli (Italy)

Tangible and intangible elements of cultural heritage are interconnected in supporting the growth of sustainable and resilient urban lifestyles. In the case of sites of historical and archaeological relevance, some spaces were conceived and designed to host specific practices (e.g., religious, musical, theatrical, political, etc.). However, the reasons for designing those historical spaces in a certain way often remain substantially unknown, due to the lack of available documental sources related to their planning. In the case of the intangible vibroacoustic field, part of this information may be retrieved by specific measurements. For this reason, we have started a preliminary experimental activity, aimed at characterizing the vibroacoustic fingerprint, i.e. the vibroacoustic site-specific features, of a private chamber concert room located inside a historic building in the center of Napoli (Italy). For such a purpose, acoustic measurements were integrated with broadband vibration measurements with a dedicated monitoring system for identifying the vibroacoustic fingerprint of the room, using time-series and frequency-based analyses.

Discrete Wavelet Transform to reduce surface scattering in GPR sections

Ground-penetrating radar (GPR) is often a fundamental tool for cultural heritage preservation. However, under some conditions, coherent noise can occur in the radargram interfering with the useful signal. Reflections from above-surface objects, such as walls or vaults, and buildings, could be recorded in the radar sections and could hide subsurface reflections linked to the structures of interest. The problem of surface scattering can be addressed by using the Discrete Wavelet Transform analysis which decomposes the signal allowing the recognition of different anomalies coming from different targets.

FEM-based models of real-time dynamic structural behavior in archaeology and monumental heritage: the case of ancient Greek colonnades

The preservation of cultural heritage buildings and infrastructures requires a multidisciplinary approach to provide a real-time knowledge of their dynamical structural behavior. For this task, an interesting and effective procedure can be based on the development of tailored dynamic models, optimized through an iterative synergic process, leaded by data provided by an adaptive and modular distributed monitoring system. A Finite Element Model (FEM) is a valid solution: it is not only an effective reference dynamical model, but it can also be used to define the potential technical requirements of the sensors (e.g., typology, sensitivity, band and number). We have applied this idea to the case of an ancient Greek colonnade, building a FEM, validated through published experimental measures. The obtained results prove that this model, behind its traditional use to describe the dynamic structural behaviour of a monument, can serve as a the basis of a tool, especially during the iterative optimization process, to define the technical characteristics of distributed structural monitoring systems.

Limited technology and unlimited results from National Museum of Ras Al Khaimah collection and its sustainability for future generations accessibility

Collection at National Museum of Ras Al Khaimah RAK face many challenges and such this research promote the first organized step to learn and apply a strategy to face these challenges. The museum hold Ethnographical, archaeobotanical and archaeological material relating to the emirate of Ras Al Khaimah provides an interesting insight into the history and traditions of this area for this we are looking for providing practical tools and building capacity to achieve sustainable development in conservation and preservation for future generations accessibility and this research about Collections Sustainability is a great opportunity to start with, and help and ensure that our museum can play their part to the fullest. Most of the collection were kept in storages and little were displayed. The research strategy was to made a condition assessment for the collection and divided them according to the priority of conservation, used for exhibitions rotation with the collection which already in display to reduce the damage effect on it and present a new vision about the hidden collection at the museum .two types of Collection were discussed here, the materials which are highly vulnerable to decay and loss and need a physical intervention for preservation and conservation such as the weapons and collection from excavation and the other type of materials which are not able to have a physical intervention and need offered to digital preservation such as archaeobotanical remains/seeds and herbarium collection.

Change Detection analysis of Cultural and Landscape Heritage based on Multispectral and Hyperspectral remote sensing data and algorithm: the case of Appia Antica Park

In remote sensing multispectral and hyperspectral Imaging are a valid method to analyse Earth Observation (EO) data. If multispectral imaging is largely used and well knowed in EO and refers to the scomposition of the spectral range of the instruments onboard in few channels (typically from 6 to 12), hyperspectral Imaging gains a greater spectral resolution and refers to obtain the spectrum for each pixel in the image, with the purpose of finding objects, identifying materials, or detecting processes through the structural analysis of the source (in SWIR range) or chemical behaviour (in VIS range). In this work a multispectral (NDVI) and hyperspectral (red edge slope) technique is used to perform a Change Detection (CD) on the vegetation of the Appia Antica Regional Park in Rome. The results show the benefits of these analyses in evaluating the state of landscape and in developing appropriate management projects.

An improved methodology for extending the applicability of Reflectance Transformation Imaging to confined sites

Recent advances in the field of imaging technologies rapidly spread new methods of representing cultural heritage, expanding the possibilities for art historians, archaeologists, restorers and conservation scientists. In this regard, Reflectance Transformation Imaging (RTI) and three-dimensional (3D) modeling using close-range photogrammetry become rapidly common and widely used by an heterogeneous public, multiplying the possibilities of understanding artworks from different points of view. This paper discusses the results that were achieved by applying these techniques to better understand the surface of a bas-relief preserved by the Egyptian Museum of Turin (Italy) in a confined site. We were able to successfully enhance the volume of engravings by integrating both RTI and 3D visualization to obtain a new investigation tool with a more suitable enlightenment.
