On Erlang B-formula and ERT method extension
2010
The key result of the paper is the theorem on traffic splitting and the ERT method extension for estimation of the throughput for schemes with traffic splitting. The excellent accuracy (relative error is less than 1%) is shown in numerical example. The paper also contains new Erlang-B formula algorithm for non-integer number of channels based on parabolic approximation.
Pietro Lojacono : restauri in Calabria e Sicilia
2022
The essay investigates the complex personality of the engineer Pietro Lojacono (Palermo 1900 - Rome 1972), who di- stinguished himself throughout his life in the field of conservation of the architectural and landscape heritage, not only in Italy, but also abroad and in particular on the island of Rhodes, in Greece . Lojacono was a man fully inserted into the cultural debate on the Restoration of monuments, able to testify to the principles acquired, but also to suggest new instances, such as maintaining authenticity, against the continuous replacement of degraded stones, up to the complete replacement of the material of the monuments. Among the many researches and restoration interventions…

The Arab - Norman civil architecture in Palermo: enhancement strategies
2013
This contribution aims to deepen the knowledge of a historical and artistic heritage of the city of Palermo, i.e. the Arab-Norman civil architecture, yet not adequately utilized, despite its importance as a World Heritage Site'. Within the three royal parks (the Old, the New and the Genoardo), the Norman kings built the palaces of Maredolce, Zisa, Cuba and Scibene, always accompanied by water, both as a lake or as a fishpond, whose purpose was primarily hedonistic as well as productive. The transmission of the architectural heritage to the future presupposes its promotion through the creation of an appropriate strategy helping to spread its knowledge and enjoyment. For example, Sicily has f…
Arc routing problems: A review of the past, present, and future
2020
[EN] Arc routing problems (ARPs) are defined and introduced. Following a brief history of developments in this area of research, different types of ARPs are described that are currently relevant for study. In addition, particular features of ARPs that are important from a theoretical or practical point of view are discussed. A section on applications describes some of the changes that have occurred from early applications of ARP models to the present day and points the way to emerging topics for study. A final section provides information on libraries and instance repositories for ARPs. The review concludes with some perspectives on future research developments and opportunities for emergin…
Analytical studies of the Sirocco room of Villa Naselli-Ambleri: A XVI century passive cooling structure in Palermo (Sicily)
2015
Abstract This work focuses on a passive cooling architecture particularly popular from the Renaissance in Palermo area, as building sumptuous suburban villas became a real hobby for the Sicilian aristocracy. A Sirocco room is an artificial subterranean construction, built close to a water spring in order to reproduce the pleasant conditions of freshness that could be experienced in a natural cavern. In these places, nobles used to spend their time with friends to escape from the hot summer. The room of Villa Naselli-Ambleri is nowadays the best preserved in Palermo thanks to its owners’ conservation care and it is unique for its cooling operating principle. The above-mentioned consideration…
Precise chronology of Polynesian temple construction and use for southeastern Maui, Hawaiian Islands determined by 230Th dating of corals
2015
International audience; Emergent archaic states in pre-contact Hawai'i used a ritual control hierarchy implemented through a system of temples to manage production, extract tribute, and reinforce the legitimacy of the ruling elites. Based on a limited sample of precise 230Th dates from coral offerings on Maui Island temples it had been hypothesized that this temple system rapidly expanded during the period from A.D. 1580–1640. We tested this hypothesis by obtaining an expanded sample of 39 new 230Th coral dates from temples in Kahikinui District, and one sample from the summit of a cinder cone that likely had ritual significance. Combined with seven coral dates previously obtained, this yie…
Facing the face – the construction of the frontal face in prehistoric and ancient two- and three-dimensional images
2020
Interpersonal communication depends to a large extent on the human face, with its many sensory organs, easily recognizable features and expression capacities. This is clearly evidenced by the abund...
Fornaci e produzioni del Golfo di Castellamare (Sicilia nord-occidentale)
2020
L’area del Golfo di Castellammare (Sicilia occidentale) è nota per le numerose fornaci di età romana. In questo articolo, si cercherà di ricostruire l’attività di un’officina destinata principalmente alla produzione di laterizi con bollo ΟΝΑΣΟΥ, databile fra III e I secolo a.C. Ricerche precedenti hanno permesso di riconoscere nel produttore di questi laterizi lo stesso Onasus Segestanus citato nelle Verrine di Cicerone e di localizzarne una possibile officina presso la Baia di San Cataldo. La scoperta di nuovi laterizi bollati e di scarti ceramici assume notevole importanza per una ricerca sugli ateliers ceramici del Golfo di Castellammare e della Piana di Partinico. Ne deriva un quadro ag…
Deep learning to detect built cultural heritage from satellite imagery. - Spatial distribution and size of vernacular houses in Sumba, Indonesia -
2021
Abstract In Sumba Island – Indonesia, the implantation of vernacular houses, inside and outside traditional villages, is considered to be an efficient proxy for the on-going complex cultural transformations resulting from globalization. This study presents an easily reproducible workflow allowing buildings to be automatically detected from satellite imagery, demonstrating how modern computer vision methods based on deep learning can help in this task, which would be far too time-consuming when undertaken by hand. Eight deep learning architectures based on convolutional neural networks were compared in terms of ability to identify and locate precisely traditional houses from satellite images…
