Un domenicano alla scoperta di antichi reperti, curiosità naturali e arte sacra: i due viaggi in Sicilia di Giuseppe Allegranza (1750-1752).

Allo scadere della metà del XVIII secolo, il domenicano Giuseppe Allegranza (1713-1785), appassionato di trouvailles antiquarie, autore di importanti trattati di archeologia cristiana, lascia il convento menegnino di Sant’Eustorgio per intraprendere un lungo viaggio alla ricerca di antichi cimeli, epigrafi ed effigi sacre, che lo porta ad esplorare la Sicilia attraverso due percorsi: prima da Messina a Siracusa, passando per Taormina, Acireale, Catania, Augusta, Lentini (inverno 1750-estate 1...

Simulating Urban Satellite-Based Vehicular Networks: Focus on Maps, Building Heights, or Vehicle Density?

Low-Earth Orbit constellations are one of the recent advancements that could provide a fresh perspective on Internet connectivity. They are appealing because they provide global coverage, they offer low round-trip-time, and they can grow to tens of thousands satellites to increase the offered capacity. However, simulating large urban areas is challenging due to the scalability limitations of the simulators. We present the results of a simulation campaign in which we improve the current state-...

CEFR-Based Assessment in Sign Languages: The Case of LSE and Perspectives for LIS

This study examines the application of the Common European Framework of Reference for Languages (CEFR) to Spanish Sign Language (LSE) in a university context, with reference to the Italian situation (Council of Europe, 2020). In Spain, CEFR descriptors are already integrated into academic programmes for the assessment of LSE, whereas in Italy the context remains uneven due to the lack of shared criteria for the teaching and assessment of Italian Sign Language (LIS). The research project, cond...

Lagoons, Marshes, and Swamps in the Roman and Late Antique Ravenna Greater Region: Settlement Patterns and Environmental Transformations

Durante il periodo romano e tardoantico, il vasto territorio intorno la città di Ravenna era in gran parte caratterizzato da un paesaggio umido, composto da lagune, paludi e acquitrini, che influenzarono profondamente l’organizzazione degli insediamenti, il comportamento sociale e la cultura dei suoi abitanti. Oggi resta ben poco di questo ambiente, e la lunga storia delle bonifiche rende ancora più complesse le indagini archeologiche e l’interpretazione dei dati attualmente esistenti. Questo...

From the Sky to the Canyons: Estimating the Visibility of LEO Satellites in Urban Environments

The future of Connected and Automated Driving (CAD) depends on resilient, ubiquitous connectivity, and Low-Earth-Orbit (LEO) satellite links are a key ingredient to achieve it. We introduce an analytical model specifically designed to predict Line-of-Sight (LoS) visibility for LEO satellite constellations from a vehicle’s perspective. Moving beyond slow, data-heavy 3D simulations, our model uses street orientation and building heights to calculate exactly how many satellites a vehicle can ”se...
