URBAN WATER INFRASTRUCTURES OF THE 20TH CENTURY IN HISTORICAL CONTEXTS: THE CASE STUDY OF THE GRABIGLIONI IN THE SASSI OF MATERA, ITALY

The Sassi of Matera represent a historical model of intelligent urbanization, integrating architecture with the natural environment through an advanced water management system. The Grabiglioni, natural watercourses, were key to controlling surface runoff and were complemented by artificial cisterns and channels, helping maintain ecological balance. These waterways shaped Matera’s unique morphology, including the Civita spur and the districts of Sasso Barisano and Sasso Caveoso. This system, i...

I percorsi dell’acqua: “musealizzare” le infrastrutture idriche storiche dei Sassi di Matera, Italia

Il paesaggio culturale dei Sassi di Matera è il risultato di una lunga strategia adattativa basata sulla gestione sostenibile dell’acqua. In questa città, l’acqua non è stata solo risorsa vitale, ma elemento determinante della struttura urbana, diventando la vera matrice della forma della città. Le falde delle colline argillose circostanti alimentavano le fontane pubbliche attraverso cunicoli sotterranei progettati per garantire un approvvigionamento costante. Il surplus d’acqua veniv...

Between water and stone—computational sonic analysis of anthropogenic transformations: the case of the Grabiglioni in Matera

This project investigates a historical water channel, Grabiglione Barisano in Matera, as both an infrastructural artefact and an aural site of memory. Once central to the hydraulic system of the city, the channel now lies invisible beneath the urban surface, yet continues to shape the cultural imagination of the Sassi. This research combines hydromorphological data, GIS analysis, and inter active sound technologies to reframe the Grabiglione as a living archive of ecological processes ...

Implementation and verification of a shock-fitting technique on SU2 code

A shock-fitting methodology for unstructured grids is implemented and verified within the open−source CFD solver SU2. The approach accurately tracks shock surfaces as zero-thickness discontinuities embedded in the computational mesh, eliminating numerical diffusion typically present in shock-capturing methods. The technique is validated through a series of test cases, including inviscid and viscous hypersonic flows, as well as fluid-structure interaction (FSI) simulations involving deformable...

Off-Grid Space-Frequency Environment Sensing for Next Generation Cognitive Radars

This paper proposes a novel 2-D spectrum sensing method to improve environmental awareness capabilities compared with traditional grid-based techniques. Instead of using fixed angles of arrival (AOA), as dictated by a grid of points, the off-grid approaches allow for flexibility in estimating angle displacements at a reduced computational complexity increase. The recovery process is formulated as a regularized maximum likelihood (RML) estimation, leveraging block-sparsity. The optimization is...
