Chapter Tra reale e virtuale: il medievale castello di Mussomeli

The 43rd UID conference, held in Genova, takes up the theme of ‘Dialogues’ as practice and debate on many fundamental topics in our social life, especially in these complex and not yet resolved times. The city of Genova offers the opportunity to ponder on the value of comparison and on the possibilities for the community, naturally focused on the aspects that concern us, as professors, researchers, disseminators of knowledge, or on all the possibile meanings of the discipline of representation and its dialogue with ‘others’, which we have broadly catalogued in three macro areas: History, Semiotics, Science / Technology. Therefore, “dialogue” as a profitable exchange based on a common language, without which it is impossible to comprehend and understand one another; and the graphic sign that connotes the conference is the precise transcription of this concept: the title ‘translated’ into signs, derived from the visual alphabet designed for the visual identity of the UID since 2017. There are many topics which refer to three macro sessions: - Witnessing (signs and history) - Communicating (signs and semiotics) - Experimenting (signs and sciences) Thanks to the different points of view, an exceptional resource of our disciplinary area, we want to try to outline the prevailing theoretical-operational synergies, the collaborative lines of an instrumental nature, the recent updates of the repertoires of images that attest and nourish the relations among representation, history, semiotics, sciences

The Rock Church of San Micidiario of the Pantalica Site and 3DLAB VR/AR–Project

This work gives the first results of a research project funded by the Sicily region, aimed at the creation of virtual reality (VR), augmented reality (AR) models, in the context of some country of the territory of Sicily with UNESCO listed monuments. This project sees the collaboration between some universities on the island and some partners who produce software and automated robotics systems and AI. Below are the first results of the workflow produced for the creation of 3D models of one of the three rock churches of the necropolis of Pantalica: an Unesco site. It also describes the process underway to get to the creation of VR and AR models to be used with three different levels of immersive reality: normal commercial viewers, different types of Oculus viewers, or in special virtual rooms Cave Automatic Virtual Environment (CAVE), already existing or created within the project

Indagini termografiche, trasformazioni architettoniche e degrado dei materiali nelle chiese del centro storico di Siliqua (Sardegna S-W)

La termografia a raggi infrarossi, come noto, consente l’analisi strutturale di manufatti edilizi sulla base dell’individuazione di zone a differente temperatura e di possibili processi di scambio termico in stretta relazione con la risposta dei materiali utilizzati alle sollecitazioni termiche a cui sono interessati. Le immagini termiche, soprattutto se acquisite mediante strumentazione caratterizzata da elevata risoluzione e sensibilità, consentono di mettere in evidenza, oltre alla presenza di anomalie legate a processi di alterazione e degradazione dei materiali utilizzati, eventuali trasformazioni architettoniche avvenute nella storia del manufatto e, in particolare, caratteri costruttivi originari nascosti da interventi posteriori. Sulla base di questi presupposti, vengono esposti i risultati di una indagine applicata per lo studio di alcuni tra gli edifici storico-religiosi presenti nel paese di Siliqua (Sardegna sud-occidentale): la Chiesa di San Giorgio, la Chiesa di Sant’Anna e la Chiesa di Santa Margherita. La ricerca, in particolare, ha consentito di mettere in evidenza la struttura e la tessitura muraria dei prospetti principali, oggi coperta dall’intonaco e, sulla base di documenti storici e delle immagini fotografiche del passato, tarare la risposta termica acquisita in base alle specifiche caratteristiche dei materiali utilizzati. Lo studio è stato condotto mediante l’utilizzo della Termocamera IR Thermo Tracer TH9260 (NEC Avio Infrared Technologies Co., Ltd).Infrared thermography, as known, allows the analysis of structural building elements on the basis of the identification of areas at different temperatures and possible heat transfer processes in close relationship with the response of the materials used to thermal stresses to which they are interested. The thermal images, especially if acquired through instrumentation characterized by high resolution and sensitivity, allow to put in evidence, in addition to the presence of anomalies associated with processes of alteration and degradation of the materials used, any architectural transformations occurred in the history of the article and, in particular, original characters constructive hidden by later interventions. Based on these assumptions, the thermographic method has been applied to the study of some of the historical and religious buildings in the country of Siliqua (south-western Sardinia): the Church of San Giorgio, the Church of Sant’Anna and the Church of Santa Margherita. The research, in particular, has made it possible to highlight the structure and texture of the main elevations of walls, now covered by plaster, and, on the basis of historical documents and photographs of the past, adjust the thermal response acquired with the specific materials used. The study has been carried through non-destructive telemetry investigations through the use of Thermal Imaging Camera IR Thermo Tracer TH9260 (NEC Avio Infrared Technologies Co., Ltd)

Digital and representation: the second line and the forgotten castle of Fiumedinisi

[EN] The Belvedere Castle of Fiumedinisi (ME) belongs to that historical heritage of Sicily characterized by abandoned and forgotten military architecture. Along the Ionian coast the defensive problem has been particularly felt over time, due to the proximity of the Turkish coast, the Middle East and the African one. The first defensive line was the coastal one, defined by principals placed on the sea in a strategic position for direct control of the coast. They were part of this group: the Maniace castle of Syracuse, that of Augusta, of Brucoli, of Catania, of Acicastello, the Tocco of Acireale, Schisò in the territory of Giardini, Capo Sant'Alessio, the Saracen Tower of Roccalumera, Capo Grosso in Ali , San Salvatore in Messina. Along the eastern side of the Peloritani mountains from Calatabiano to Messina, the island's defensive strategy also included a second line of fortifications, which controlled a more distant horizon from their position. These include the castle of Calatabiano, Taormina, Castelmola, Forza d’Agrò, Savoca, Fiumedinisi, Scaletta Zanclea, Santo Stefano di Briga, Matagrifone. Among them, the Belvedere castle of Fiumedinisi, at a critical distance from the village, so as to be in a state of neglect, among those listed is that which is in the worst conditions. In stark contrast to the dignity and history of the site and territory of Fiumedinisi, dating back to the Greek period. In this work we propose the survey of the castle with digital, photogrammetric technologies, Structure From Motion (SFM) and dense matching, to arrive at a 3D documentation and graphic drawings, considering that to date there are no significant scientific surveys and representations of this abandoned fortress.Di Gregorio, G.

FAST TRACK NELLA PROTESI DI GINOCCHIO

L'approccio fast track alla protesi di ginocchio ha l'obiettivo di garantire una riduzione dei tempi di degenza senza un aumento delle complicanze. L'elemento chiave è l'approccio multidisciplinare e una particolare attenzione al dolore post operatorio e al sanguinamento..
