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.

Traces of Polychromies in Roman sculpture: a multi-analytical approach

Recently, some museums started seeing in a new light their collections and searching for overlooked traces of painted colours: one example is the National Archaeological Museum of Aquileia, nowadays in north-eastern Italy, a Roman city close to the Adriatic Sea.
Among the sculptures with an easily recognizable polychromy, five were chosen (three statues, a funerary relief and a fragment of architectural decoration), in order to give new and unpublished information about the colours on marble and stone of the Roman Aquileia between the 1st century BC and the 3rd century CE, with the support of a multi-analytical approach (imaging, FORS, Raman and microsamples).

Analyzing an Ancient City: Non-invasive Studies of Ostia Antica Archeological Park s Wall Paintings

Roman wall paintings at the archeological site of Ostia Antica dating from the 1st century BCE to the 4th century CE were studied in an integrated non-invasive approach using portable instrumentation, namely: Nuclear Magnetic Resonance (NMR), Hyperspectral Imaging (HSI), X-Ray Fluorescence (XRF), Visible Induced Luminescence (VIL), External Reflectance Fourier-Transformed Infrared Spectroscopy (ER-FTIR), Raman and Near Infrared (NIR) Spectroscopies. The objective of this study is threefold: to investigate the materials and techniques of wall paintings at Ostia Antica in order to gain insight into the evolution of the use of materials and painting techniques over time, the testing of novel instrumentation in archeological contexts such as portable HSI and the recently developed NMR hardware and stratigraphy protocols, as well as to aid in the conservation efforts at the site by providing information on the material composition of the walls. Some of the main results of four campaigns dating 2019-2023 are presented.

Extended BIM: a proposed workflow for the integration of the HBIM and EM approaches

The present research proposes the beta version of a collaborative workflow which aims at linking HBIM and Extended Matrix using Open-Source coding and visualisation tools. The developed workflow was tested on a significant case study, the Roman Theatre of Terracina, whose excavation works started in 2019 and were initially documented through an integrated TLS and UAV digital survey. In 2021 and 2022 the excavation data were updated, also using SLAM technology, thus the proposed approach focuses on the systematisation of the analysis and processing of the data regarding the consecutively surveyed excavation phases.

HBIM for restoration project and data management of a religious complex

The paper presents the first results of a research project aimed at digitizing the restoration process of the monastic complex of Santa Maria a Graiano, located in Fontecchio (AQ). The parametric model allows the management of heterogeneous data derived from multidisciplinary knowledge processes and facilitates data sharing. The representative modelling of the artefact after the damage caused by the 2009 earthquake, to which the planned restoration operations were linked, compared to the parametric model of the artefact after restoration, allowed cooperation between different professionals, in addition to the documentation of the work carried out. In this way, the model assumes a central role in the knowledge process but also the heritage management process as it facilitates the choice of conservation strategies to be implemented on the asset in future years and to preserve the memory of the interventions carried out, simplifying the maintenance process in the as-built phase.
