- Ribbed vaults with Renaissance characteristics: singular design and
construction in some of Diego Siloé’s vaults
Authors: Eduardo Acosta
Abstract: The Renaissance architect Diego Siloé designed the parish church in Iznalloz in 1549 in the Renaissance style but covered the nave and aisles with medieval ribbed vaults. The analysis of these vaults reveals that the architect sought a consensual solution and designed “Roman-style” ribs to integrate the vaults into the general discourse of the church. This adaptation, commonly found in mid-sixteenth-century Spanish architecture, produced singular solutions that highlight the state of the technique and the thinking of Diego Siloé.

- Architectural Intangible Heritage and Graphic Reconstruction.
Terminological and Philological Notes
Authors: Fabio Colonnese
Abstract: UNESCO’s extension of the concept of heritage to intangible has been changing the status of architectural designs and the operative frame of the practice of architectural reconstruction. The variety of reconstruction cases requires specific procedures and terms. The terms are here investigated by an analysis of the historical and theoretical roots of such a practice, segnately on the figure of Quatremère de Quincy; the procedures are discussed by means of a series of personal experiences on literary architecture, architectural projects, fictive architecture. They are retrospectively analysed from the point of view of the sources –to define both the content and the appearance – which can be endogenous to the document/monument (and prioritary) or exogenous, with a focus on the transparency of procedure.

- Industrial Metrological Technologies for Cultural Heritage
Authors: Cecilia Maria Roberta Luschi; Alessandra Vezzi
Abstract: The work addresses the issues related to the survey of small-sized artifacts made of reflective materials. This is the case of a bronze horse, possibly part of a group with praying figures, kept at the MuVet in Vetulonia. Modern technologies applied during the survey phase encounter difficulties that are hard to overcome in this case. The topic becomes paradigmatic in terms of problem-solving and the adoption of ad hoc technologies. Reflective materials, in general, pose problems on the metric reliability of the three-dimensional model. Therefore, ensuring high reliability for small-sized objects becomes the crucial challenge in order to provide degradation analysis and make the processing details visible. In the case under examination, the representation has realized a reliable model with a deviation of around 0.05 mm, managing to represent the object at a scale of 5:1 with emerged details that were previously invisible even to a high-resolution photographic campaign.

- Sculptural fragments from the church of San Gennaro extra moenia in
Naples: digital twins for heritage knowledge, analysis and fruition
Authors: Greta Attademo
Abstract: This paper examines the role that new technologies and digital representation strategies can play in the conservation and enhancement of the medieval sculptural heritage, often difficult to understand due to its fragmented and lacunar state. The case study presented is the apparatus of sculptural fragments belonged to the Church of San Gennaro Extra Moenia in Naples and today preserved in the Palatine Chapel of the Castel Nuovo Museum. The creation of a library of digital twins becomes a useful tool for academics, enabling them both to enrich their knowledge of sculptural fragments and to advance hypotheses and reconstructive analyses in a digital environment. The design of a virtual reality experience through the use of QR codes and Google Cardboard also allows the creation of new ways of fruition of medieval heritage, especially for non-expert audiences who do not always appreciate traditional methods of cultural meaning transmission.

- HBIM as a tool for heritage presentation of Santa Maria in Trastevere
Authors: Alfonso Ippolito; Martina Attenni, Rawan Darwa
Abstract: 3D laser scanning and Building Information Modeling (BIM) provides benefits such as optimizing the BIM process, increasing accuracy, and coordinating with multiple information in the same place. Applying BIM to document the Church of Santa Maria in Trastevere resulted in a comprehensive 3D model of the church documenting its history and architecture. BIM enables multidisciplinary model checking, automatic review of designs, and three-dimensional simulation. Parametric modeling establishes best practices and enables automatic updates. As well as playing a crucial role in achieving the management and development of cultural heritage, providing a comprehensive view of buildings based on three-dimensional models with "smart objects" that contain information about themselves and their relationships to other objects.

- Cultural heritage recovery in rural Spain through digital means of
surveying and graphic reconstruction. Case study of El Paular wool complex
Authors: Nicolás Gutiérrez-Pérez
Abstract: The article exposes a research experience around the recovery of the industrial and cultural heritage located in the Spanish rural environment that is in ruins and with clear signs of disappearance. As an example, we will analyze the large wool processing center built in 1624 by the Royal Monastery of El Paular in the small village of Trescasas (Segovia) and which today has practically disappeared after being abandoned and plundered after the French invasion (1808-1814). The methodology can be summarized in a deep historical archival documentation, in the survey work with new digital means (laser scanner, drone, photogrammetry, etc.), in the elaboration of the hypotheses, as well as in the virtual reconstruction through 3D modeling and image rendering. Consequently, the primitive configuration of the building is exposed, determining the morphology of its rooms, its function and its historical offices, contributing to the preservation of this cultural heritage.

- Virtual access to heritage through scientific drawing, semantic models and
VR-experience of the Stronghold of Arquata del Tronto after the earthquake
Authors: Fabrizio Banfi; Chiara Stanga, Angelo Giuseppe Landi
Abstract: Interactive representation has proven to be an effective tool in various disciplines related to Digital Cultural Heritage (DCH). This study proposes a research method that uses interactive representation to share complex scenarios like the Stronghold of Arquata del Tronto, facilitating novel forms of heritage dissemination. The scan-to-BIM process made it possible to digitise complex structural elements damaged by the 2016 earthquake. The investigation of the complexity paradigm improved the reliability of the semantic model that supports the preservation process. Interoperability and accessibility paradigms were explored to create a more comprehensive and accurate understanding of the built heritage. A web-VR platform was developed to enhance user interaction and simplify virtual environment exploration without using complex hardware (VR headset and controllers), making it possible to experience VR in the browser.

- 3Dcitymodels to support technical knowledge and management of historic
built environments. A semantic CityGML-based model for the ancient core of
Carovigno (BR), Italy
Authors: Margherita Lasorella; Elena Cantatore
Abstract: The study presents the characterization of the built environment in historic districts according to the CityGML standard, properly prepared for their management in recovery plans. Knowledge, conservation, and management of such urban areas require a detailed data collection phase and a multi-scale representation technique to describe all the geometric and thematic aspects. To this end, the work identifies the system of simple and complex parameters, namely descriptors and factors, analysing theoretical notions, regulations, and previous scientific studies and experiences, mainly focused on the Italian case. Descriptors and factors are categorized along with the thematic relations with urban and building elements and components, through a well-defined logical-relational scheme and consistently related to the CityGML standard. Finally, the system of descriptors and factors has been applied and validated to the ancient core of Carovigno, in Apulia Region (Italy).

- Machine learning and landscape quality. Representing visual information
using deep learning-based image segmentation from street view photos
Authors: Fabio Bianconi; Marco Filippucci, Marco Seccaroni, Andrea Rolando, Domenico D'Uva
Abstract: The study is centered on the value of visual perception in the measurement of landscape quality. The research aims to define a digital methodological process and criterion for assessing the quality of a landscape, using along a road georeferenced image as open source big data. Artificial intelligence system, trained to recognize and quantify the elements present, processes these images associating area data, therefore converted them into values according to specific criteria. In each image, it evaluates positive or negative characteristics of the path, and the sum of all big data values generates an index (L-value). This approach is tested in different case studies, validating AI results with Collective Intelligence, using anonymous questionnaires. The proposed process transforms the perceptual data inherent in the photographs into information, from which it extrapolates a knowledge path synthesized in map, representation of perceived qualities of the landscape.

- Digital visualization for cultural dissemination
Authors: Davide Mezzino
Abstract: Considering the consolidated use of visualization techniques for cultural heritage dissemination, the article illustrates different approaches to present archeological sites and museums’ collections. Through two case studies within the archeological field -the UNESCO cultural heritage site of Bagan and the Museo Egizio di Torino- creative uses of virtual reality (VR) and multimedia technologies and the related communication and interpretation opportunities are presented. By explaining the adopted workflows (from data/information acquisition to information processing and elaborated dissemination strategies), the contribution focuses on the role of graphic language and digital representation in defining narrative strategies addressed to heterogeneous audiences. Additionally, the expressive potential of digital visualization techniques for both online and onsite cultural communication is highlighted.

- Augmented Reality (AR) in education, medicine and industry: a systematic
review of literature
Authors: Gonzalo Alfonso Beltrán
Abstract: Over the years, it has been observed how new technologies have grown as is the case with augmented reality. For this reason, it was pertinent to carry out a systematic review of the literature in order to establish and discuss the state of the art of the application of AR in education, medicine and industry. Therefore, 25 articles were analyzed in the homogeneous secondary databases IEEE, SciELO, Elsevier, ScienceDirect and EBSCO for the analysis of substantive variables (sample, thematic and countries) and methodological variables (designs and study periods) to continue exploring and understanding the trends of in-depth studies, considering a 7-year period of inquiry. As a result of this outline, the augmented reality state of the art was presented as a transcendental milestone and its amplitude within the constructs of this study, leaving open the need to investigate other contexts of approach to this topic of interest.

- Similarity based optimization to fractal image encoding based on
multithreading parallelization
Authors: Ranjita Asati; Mukesh Raghuwanshi, Kavita Singh
Abstract: E Higher compression time is a major issue in adoption of fractal image coding even though it offers various advantages in terms of higher compression ratio, higher resolution, and lower decompression time. Many optimizations have been proposed earlier to reduce the computation time in terms of parallelism and encoding space reduction. This work proposes an integrated approach combining both multithreaded parallelism and similarity based encoding space reduction to diminish the time of compression in Fractal image coding. The compression time of the proposed integrated method is tested for images of different resolution and the proposed solution is able to reduce the compression time by almost 4.4 times compared to existing fractal image compression techniques.

- Midjourney experimentation: representing Nature on a macro scale
Authors: Alice Palmieri
Abstract: The paper presents the premises for a research project on the subject of Human-Nature interaction, with a focus on the role that the discipline of representation can play as a tool for investigation, experimentation and as a vehicle for content aimed at increasing awareness. Through a path made of surreal, invisible and natural images, the basis for a reflection on the role of representations through AI will take shape, referring to the theme of Nature as a contemporary field of experimentation. The aim will be to construct representative artefacts inspired by Nature, using digital technologies and material manipulations, for the increase of an ecological awareness through an up-close and surreal point of view. The project in which this line of research is placed is "Designing with more-than-humans", funded by University of Campania "Luigi Vanvitelli”.
