Valorizzare il centro storico di Palermo: un cambio di paradigma
2022
The contribution starts from a basic question that is whether the historical centres of large cities can escape the same destiny exclusively based on the historical heritage excellence, on tourism and cultural activity or can continue to play the role of a vital urban structure with a mix of social groups, of ordinary functions and activities as the residential one. Moreover, the historical centre tendency to transform into predominantly commercial and touristic areas has had surreal implications during the period of lockdown caused by Covid-19 pandemic, when the most valuable parts of our cities were totally emptied of human presence. This is also confirmed in the case of the historical ce…
I paesaggi urbani "generati" dalle politiche attuate ad Agrigento in seguito alla frana del 1966
2020
After more than fifty years after the landslide of 19 July 1966 which involved most of the historical centre of Agrigento, the paper aims to reflect on the results of the policies implemented by the national government as a result of this dramatic event and on the effect that such policies have had on urban landscape. In particular, the paper focuses on the degradation conditions that characterize both the historical neighbourhood of Rabato-Santa Croce, which was partially abandoned by the inhabitants following the landslide, and the new district of public housing "Villaseta", built outside of the Agrigento city, where the inhabitants - who had lost their homes - were transferred.
Cities inside the City on River Amstel
2017
Paramaribo, Curaçao, Jakarta. Se utilizzassimo il linguaggio gastronomico, potrebbero suonare rispettivamente come moksie alesie (il coloratissimo riso misto a carne, pollo, verdure, fagioli bianchi, peperoncino e latte di cocco), planteur (il rinfrescante long drink con il frutto di guava, ananas, melograno, arancia, rum agricolo, cannella e noce moscata), nasi goreng (il classico piatto unico indonesiano a base di riso fritto, pollo e gamberetti). Per gustarli tutti dovremmo compiere un impegnativo tour attorno al pianeta, dal Suriname alle isole caraibiche e spingerci fino all'Indonesia. Oppure potremmo scegliere un'alternativa forse più interessante: passeggiare comodamente tra i canali…
Vivere la città in evoluzione: il ruolo dei paesaggi urbani storici
2021
Cultural and social aspects in post pandemic age are mainly connected with land use, mainly in high-density urban contexts. It is relevantly in historical centres where urban communities ask for spaces for cultural activities, creativity, aimed at social cohesion. The paper describes this condition in UNESCO Historical Urban Landscape Policy and demonstrates in what way it can be applied at Palermo Historical Centre.
Urban Collage
2018
Il contributo propone una riflessione progettuale, elaborata durante il workshop internazionale “Hong Kong – Palermo. Fluid cities”, sulla rigenerazione del waterfront centrale della città di Palermo, approfondendo l’area dell’antico quartiere della Kalsa. Come una membrana porosa, tramite osmosi, il progetto contaminerà la città generando nuovi cluster culturali: il ‘Cultural Hub’ (l’epicentro); il ‘Food Cultural District’ (la Vucciria); il ‘Living Lab/Residenza per artisti’ (l’attuale Palazzo delle Finanze).
TORSIONAL STRESS CONCENTRATIONS IN SHAFTS: FROM ELECTRICAL ANALOGIES TO NUMERICAL METHODS
2013
This paper presents the historical development of methods used for the study of torsional stresses in shafts. In particular the paper covers both analog methods, in particular those based on electrical analogies proposed since about 1925, and numerical methods, in particular finite difference methods (FDM), finite element methods (FEM) and boundary elements (BEM).
A knowledge based architecture for the virtual restoration of ancient photos
2017
Abstract Historical images are essential documents of the recent past. Nevertheless, time and bad preservation corrupt their physical supports. Digitization can be the solution to extend their “lives”, and digital techniques can be used to recover lost information. This task is often difficult and time-consuming, if commercial restoration tools are used for the purpose. A new solution is proposed to help non-expert users in restoring their damaged photos. First, we defined a dual taxonomy for the defects in printed and digitized photos. We represented our restoration domain with an ontology and we created some rules to suggest actions to perform in case of some specific events. Classes and …
PHOTOGRAMMETRY NOW AND THEN - FROM HAND-CRAFTED TO DEEP-LEARNING TIE POINTS
2022
Abstract. Historical images provide a valuable source of information exploited by several kinds of applications, such as the monitoring of cities and territories, the reconstruction of destroyed buildings, and are increasingly being shared for cultural promotion projects through virtual reality or augmented reality applications. Finding reliable and accurate matches between historical and present images is a fundamental step for such tasks since they require to co-register the present 3D scene with the past one. Classical image matching solutions are sensitive to strong radiometric variations within the images, which are particularly relevant in these multi-temporal contexts due to differen…
3D Map Computation from Historical Stereo Photographs of Florence
2018
The analysis of early photographic sources is fundamental for documenting and understanding the evolution of a city so rich in history and art as Florence. Indeed, by the 1860s several photographers used to work in town, and their images (often obtained through stereoscopic set-ups) can help us to reconstruct Florence in 3D as it was by the time of the Italian unification. The first and most delicate part of such reconstruction process is the computation of disparity maps from the historical stereo pairs. This is a very challenging task for fully-automatic computer vision algorithms, since XIX century photographs are affected by several problems—ranging from superficial damages to asynchron…
