Digitization and Preservation of Cultural Heritage Products

2017

Cultural heritage encompasses various aspects of a nation's history. Cultural heritage artifacts are considered as priceless items that need special care. Since the wide adoption of new digital technologies, documenting and storing cultural heritage assets became more affordable and reliable. These records are then used in several applications. Researchers saw the opportunity to use digital heritage recordings for long-term preservation. They are considering cultural heritage artifacts as products, and the history behind them as a product lifecycle. In this paper, we present the research progress in cultural heritage digital processing and preservation, highlighting the most impactful advan…

Francesco La Grassa. Disegno e Architettura

2022

Francesco La Grassa fu un architetto e ingegnere siciliano che operò nella prima parte del Novecento tra la Sicilia e Roma: protagonista, sebbene ‘minore’, di una florida stagione architettonica segnata dalla collaborazione con una committenza colta e illuminata, fu uno degli allievi più fedeli di Ernesto Basile. Questo studio non ha interessato l'intera opera del progettista, ma soltanto le architetture non realizzate e quelle scomparse in seguito ad atti di demolizione. Tale selezione di progetti è stata analizzata attraverso un metodo d'indagine basato sull'applicazione degli strumenti della Scienza della Rappresentazione, quali Disegno, Rilievo, Analisi grafica, Modellazione tridimensio…

Metodi per la ricostruzione virtuale e la visualizzazione di opere d'architettura perdute

2022

Digital technologies for architecture representation have strongly modified uses and rules inherited from a millennial tradition. In the initial development period CAD tools worked as electronic drafting machines and digital drawings were almost similar to hand-made drawings; plans, fronts, sections and the like. In this period perspective and axonometric drawings were rarely executed because architects realized that these drawings had to be substituted by 3D digital models views, but modeling tools were not so familiar to professionals, both for software and hardware limitations. The evolution of architecture digital representation is still in progress, but it is possible to outline a prec…

HR3DHG version 1: modeling the spatiotemporal dynamics of mercury in the Augusta Bay (southern Italy)

2020

The biogeochemical dynamics of Hg, and specifically of its three species Hg0, HgII, and MeHg (elemental, inorganic, and organic, respectively), in the marine coastal area of Augusta Bay (southern Italy) have been explored by the high-resolution 3D Hg (HR3DHG) model, namely an advection–diffusion–reaction model for dissolved mercury in the seawater compartment coupled with a diffusion–reaction model for dissolved mercury in the pore water of sediments in which the desorption process for the sediment total mercury is taken into account. The spatiotemporal variability of the mercury concentration in both seawater ([HgD]) and the first layers of bottom sediments ([HgDsed] and [HgTsed]), as well…

A new reading of Bronze Age funerary structures in Mongolia through the analysis of their architectural elements, arrangement and form

2022

The archaeological landscape of Mongolia is marked by the presence of numerous funerary monuments (khirigsuurs) and engraved stelae (deer stones), erected by nomadic populations at the end of the Bronze Age. The first observations indicate great regularity in the choice and arrangement of the architectural and iconographic elements at the time when these structures were built. This regularity suggests the existence of shared traditions and social coherence between nomadic communities in a territory covering almost twice that of France. The data available today do not provide sufficient perspective to establish social models at the level of a province, and even less so at the scale of the co…

Computational Modeling of Ascending Thoracic Aortic Aneurysm and Dissection

3D digital tools for the archaeological massive artifacts documentation

2022

This study focuses on 3D acquisition and documentation procedures, innovating and implementing traditional survey methods to promote and increase the efficacy of the historical and archaeological heritage fruition. Especially within museum itineraries, modern digital technologies, if consistently applied, can promote a better interpretative reading, implementing the knowledge of scholars. Moreover, in coherence with the Horizon Europe “Cultural Heritage” area of intervention, for a new future inextricably linked to the history of Cultural Heritage, it is essential to experiment approaches that favor innovative mechanisms of fruition and promotion of works of art, based on the idea that the …

SUSTAINABLE AGRICULTURE MANAGEMENTS TO CONTROL SOIL EROSION

2021

[EN] High rates of soil erosion compromise sustainable agriculture. In rainfed agricultural fields, erosion rates several orders of magnitude higher than the erosion rates considered tolerable have been quantified. In Mediterranean rainfed crops such as vineyards, almonds and olive groves, and in the new sloping citrus and persimmon plantations, the rates of soil loss make it necessary to apply measures to reduce them to avoid collapse in agricultural production. Managements such as weeds, catch crops and mulches (straw and pruning remains) are viable options to achieve sustainability. This work applies measurements through plots, simulated rainfall experiments and ISUM (Improved Stock-Unea…

History, Iconography and Digital Drawing for Architectural Heritage: The Case Study of the Church of S. Nicolò alla Kalsa in Palermo (Sicily)

2022

This contribution aims to test the efficiency of a research methodology based on an interdisciplinary approach. This is to be achieved through the case study of the disappeared church of S. Nicolò alla Kalsa in Palermo, an imposing medieval building dating back to the thirteenth and fourteenth centuries and demolished after an earthquake in 1823. The reconstruction of the original configuration of this disappeared monument was achieved through traditional research sources and tools in the field of architectural and urban history, as well as architectural drawing, relying on both traditional and up-to-date digital technologies. The main source used for this virtual reconstruction is a rich h…

Image-based 3D reconstruction using traditional and UAV datasets for analysis of road pavement distress

2018

Abstract On local and urban networks, the enduring issue of scarce resources for Maintenance, Rehabilitation, and Reconstruction strategies (MR&R) has led, in many cases, to using unadjusted or poor techniques for road pavement distress detection and analysis, yielding ineffective or even counterproductive results. Therefore, it is necessary to have tools that can carry out quick, reliable and low-cost assessment surveys. This paper aims at validating the use of innovative and low-cost technologies for road pavement analysis, assessing their potentialities for improving the automation and reliability of distress detection. A Structure from Motion (SfM) technique is analyzed at different alt…
