VIRTUAL REALITY FOR URBAN PLANNING. THE PORT OF PALERMO: PAST, PRESENT AND FUTURE
2020
Virtual reality is proving to be an interesting tool for the visualization of 3d models developed for urban planning. It allows not only interactive visualization, but also the possibility of inserting analogical and informative contents. The case study relates to the development of a 3D model viewable in virtual reality of the Port of Palermo area, of great urban, historical and logistical interest. The system allows the visualization of its current state, historical emergencies and future developments, as well as the comparison between existing services and those planned in the reconfiguration project.
La perduta Chiesa dell'Annunziata presso Porta san Giorgio a Palermo: ipotesi e ricostruzioni virtuali
2020
The Annunziata church was destroyed by the bombings of the Allies on May 9 1943 on the city of Palermo. However, important evidence remains of the church, built at the end of the 16th century and located near the San Giorgio gate: a 1832 drawing by Pierre-Joseph Garrez, preserved in Paris, at the École nationale supérieure des Beaux-Arts, the survey of the architect Nino Pollaci of the early twentieth century, a series of historical photos, the surviving architectural fragments such as the capitals and the painted wooden coffered ceiling, preserved in various Palermitan museums, and above all the bell tower, still the only trace on the site of the now disappeared church of the Annunziata. T…
Osservare l’Universo. La specola astronomica nel Palazzo Reale a Palermo
2009
L’interpretazione, la comprensione e la rappresentazione della volta celeste, la misurazione del tempo e l’osservazione dello stato del cielo con i suoi complessi fenomeni fisici hanno da sempre suscitato nell’uomo il desiderio di poter scorgere l’essenza e l’origine della sua vita, proponendo sfide intellettive volte a carpire e a spiegare le leggi che governano l’Universo. Oggi, l’Assemblea Generale dell’ONU ha dichiarato il 2009 Anno Internazionale dell’Astronomia, ravvivando il dibattito scientifico con studi e ricerche che arricchiscono il patrimonio culturale. Il presente studio vuole porre l’attenzione al luogo architettonico della Specola con annessi i locali propri dell’Osservatori…
L’ORTO BOTANICO DI PALERMO: IL GYMNASIUM
2012
On the base of a valuable documentation of project drawings, sketches and old survey, the Author proposes inedited graphic studies aimed to critically revisit all neoclassical buildings of the gymnasium and the “stoves” that it is it possible to see at the Botanical Garden of Palermo. The charming open-air laboratory that the Botanical Garden of Palermo offer to visitors and experts, in the urban landscape of Palermo, shows how Architecture, Art and Decoration coexist in a synergistic experiment.
Designing for Mixed Reality Urban Exploration

Publisher Copyright: © 2021. All Rights Reserved. This paper introduces a design framework for mixed reality urban exploration (MRUE), based on a concrete implementation in a historical city. The framework integrates different modalities, such as virtual reality (VR), augmented reality (AR), and haptics-audio interfaces, as well as advanced features such as personalized recommendations, social exploration, and itinerary manage…
Immersive Virtual Reality for Cultural Heritage Exploration
2023
Virtual Reality can provide an immersive experience that allows cultural heritage to be experienced in a more realistic and immersive way than traditional showcasing techniques. The objective of this paper is to provide a software pipeline that can be adopted for the realization of immersive experiences in cultural heritage sites. This work has been realized within the 3DLab-Sicilia project, which includes the realization of immersive virtual tours of UNESCO World Heritage sites located in the Sicily area (Italy).
Question Answering with BERT: designing a 3D virtual avatar for Cultural Heritage exploration
2022
Recent technological developments are changing how people experience physical and virtual environments. Technologies like Virtual Reality (VR), Augmented Reality (AR), and Mixed Reality (MR), today, are impacting daily life and are being used in various domains including Cultural Heritage. Applying intelligence to applications using these technologies, through AI and Deep Learning can provide a more immersive user experience. In this paper, we propose the design of a system that realize an avatar with question-answering capabilities, for the specific purpose of giving help in immersive navigation of cultural heritage sites. It is based on a BERT model tailored to the Italian language and wi…
Virtual Element based formulations for computational materials micro-mechanics and homogenization
2021
In this thesis, a computational framework for microstructural modelling of transverse behaviour of heterogeneous materials is presented. The context of this research is part of the broad and active field of Computational Micromechanics, which has emerged as an effective tool both to understand the influence of complex microstructure on the macro-mechanical response of engineering materials and to tailor-design innovative materials for specific applications through a proper modification of their microstructure. While the classical continuum approximation does not account for microstructural details within the material, computational micromechanics allows detailed modelling of a heterogeneous…
Virtual Element Method: Micro-Mechanics Applications
2020
In this contribution we present an application of the lowest order Virtual Element Method (VEM) to the problem of material computational homogenization. Material homogenization allows retrieving material properties through suitable volume averaging procedures, starting from a detailed representation of the micro-constituents of the considered material. The representation of such microstructure constitutes a remarkable effort in terms of data/mesh preparation, especially when there is not evident microstructural regularity. For such a reason, computational micromechanics may represent a challenging benchmark for showing the potential of VEM. In this contribution, polycrystalline materials ar…
Stability of Microgrids: An Application of Virtual Synchronous Generator
2022
The objective of this paper is to illustrate an alternative control algorithm for power converters which have the task of introducing the energy generated by systems based on the use of renewable sources such as, photovoltaic or wind power, in to small-sized networks, microgrids. Virtual Synchronous Generator can operate both in parallel to the main network as well as in isolated and autonomous conditions (islanding-mode). The contribute of this work is to drive a consolidate approach, made in time domain, in a more flexible and less time-consuming approach based on Park transformation.
