Recovering Sicilian Silk Heritage through Digital Technologies: The Case of Piraino’s Collection
2022
Textile conservation has given rise to small and medium-sized museums, usually with scarce resources. In Sicily, the little evidence that remains of silk production and opulent imports by the rich and powerful local aristocracy is kept in museums, parishes, and other cultural institutions. The documentation, dissemination, and enhancement of such a fragile heritage is today possible by means of technological tools that provide novel means to preserve, analyze, and exploit digital information. In this paper, we present some outcomes of the SILKNOW project, a project that applies computing research to the needs of diverse users (museums, educational institutions, the tourism industry, creativ…
A Multi-Projector Calibration Method for Virtual Reality Simulators with Analytically Defined Screens
2017
The geometric calibration of projectors is a demanding task, particularly for the industry of virtual reality simulators. Different methods have been developed during the last decades to retrieve the intrinsic and extrinsic parameters of projectors, most of them being based on planar homographies and some requiring an extended calibration process. The aim of our research work is to design a fast and user-friendly method to provide multi-projector calibration on analytically defined screens, where a sample is shown for a virtual reality Formula 1 simulator that has a cylindrical screen. The proposed method results from the combination of surveying, photogrammetry and image processing approac…
Mondi virtuali e realtà virtuale. Un’analisi del fenomeno nella formazione sanitaria
2019
Negli ultimi sei anni la realtà virtuale (VR) e i mondi virtuali (VE) sono diventati sempre più tecnologicamente avanzati e molto più accessibili per quel che riguarda l’accesso economico. In sanità essi vengono utilizzati principalmente per cinque scopi: formazione degli studenti; formazione dei professionisti (simulatori); riabilitazione/terapia; cura/diagnosi e gestione del dolore. In questa review abbiamo analizzato 2.252 articoli pubblicati tra il 2012 e il 2019 su PubMed ed abbiamo organizzato gli articoli nelle aree simulazione per studenti; simulazione per specializzandi; simulazione avanzata per professionisti; applicazioni nei campi medico/dentale/infermieristico (soft skills); re…
Presència virtual de les universitats andaluses
2009
En aquest article exposarem de manera específica les iniciatives portades a terme en les universitats andaluses per fomentar, reforçar i estendre la seva presència virtual a la xarxa. Farem un recorregut pels serveis inculats amb la tecnologia i suport a l'ensenyament, els campus i aules virtuals presents en cadascuna d'aquestes universitats, així com pels esforços realitzats per La xarxa d'Universitats Virtuals Andaluzas per a la creació i desenvolupament del Campus Virtual Andaluz del qual formen part totes les universitats andaluses a través d'una àmplia oferta d'activitats d'ensenyament en línia.
Fragment‐ and Negative Image‐Based Screening of Phosphodiesterase 10A Inhibitors
2019
A novel virtual screening methodology called fragment‐ and negative image‐based (F‐NiB) screening is introduced and tested experimentally using phosphodiesterase 10A (PDE10A) as a case study. Potent PDE10A‐specific small‐molecule inhibitors are actively sought after for their antipsychotic and neuroprotective effects. The F‐NiB combines features from both fragment‐based drug discovery and negative image‐based (NIB) screening methodologies to facilitate rational drug discovery. The selected structural parts of protein‐bound ligand(s) are seamlessly combined with the negative image of the target's ligand‐binding cavity. This cavity‐ and fragment‐based hybrid model, namely its shape and electr…
An intangible smart city inside the tangible historical city: the smart heritage as regeneration of euromediterranean realities
2013
The Hybridization between the visible and virtual territory has become a commonplace for much of urban population. The city is mutating into an extended form in which the visible and virtual dimensions are blurred. In this sense, the city has a physical dimension that we appropriate differently and a semiotic dimension that allows us to communicate and establish social bonds. The abstract examines how European policies is facilitating the construction of smart cities which have a cultural heritage to be safeguarded.
How to get things done in social virtual reality : A study of team cohesion in social virtual reality–enabled teams
2022
Social virtual reality (SVR) enables teams to operate in a virtual environment that simulates and enhances real-world interactions. However, there is an absence of empirical analysis of how SVR can affect the performance of virtual teams. This paper documents how SVR affects the formation of team cohesion (i.e., task cohesion and social cohesion), which is a critical success factor for team performance. To address this gap in the research, we conducted a qualitative study by interviewing 20 members from virtual teams assigned to perform a challenging collaborative task in SVR. As a contribution, our study identifies five primary affordances and 11 sub-affordances for team cohesion in SVR. W…
L'ama del corral i del carrer: la construcció del discurs "agora-dona" en les comunitats virtuals d'atenció de Facebook
2022
Aquesta tesi parteix de tres preguntes d'investigació: funcionen les comunitats virtuals de persones agorafòbiques com a GAM's (grups d'ajuda mútua), és a dir, espais en els quals les persones usuàries atenen, gestionen i signifiquen la seua agorafòbia?; com se significa i construeix socialment, i quines implicacions té, el diagnòstic d'agorafòbia per a les persones identificades com a dones dins d'aquests espais?, i; quines estratègies creatives de resistència desenvolupen els subjectes diagnosticats com a dones i com a agorafòbiques? A partir d'ací, ens aproximem a la realitat que volem conéixer a partir de la postura epistemològica dels coneixements situats, i mitjançant una metodologia …
Dal disegno alla misura. Ricostruzione del fronte di palazzo Aiutamicristo a Palermo
2020
I laser scanner e la fotogrammetria SfM hanno scardinato il legame tradizionale fra misura e disegno, fissato negli eidotipi che spesso prefiguravano i disegni di restituzione. Il contributo che segue intende dimostrare, attraverso una esemplificazione su un caso studio, che le tecnologie digitali e il lavoro di indagine su repliche del reale, esaltano, attraverso nuovi modi di interazione fra disegno e misura, la possibilità di indagare l’architettura costruita per decodificarne lo schema, il progetto. Il caso studio prescelto è il fronte principale di palazzo Aiutamicristo, costruito a Palermo a partire dal 1490 su progetto di Matteo Carnilivari. Il prospetto di palazzo Aiutamicristo avrà…
Afterword
2023
It is well known that the disciplines of representation contain many souls, from visual communication to the history of representation, from relief drawing to project drawing, from descriptive geometry to digital transitions; and then there are two great strands, the architectural and the engineering, one more humanistic, the other more technical.
