Antonio Belguardo. Un maestro nella Palermo tra XV e XVI secolo: il regesto documentario
2016
Le informazioni documentarie emerse in questi ultimi anni sulla figura di Antonio Belguardo permettono di tracciare con maggiore compiutezza il profilo biografico e la parabola professionale di uno dei più prolifici protagonisti della stagione tardogotica dell’architettura siciliana; la sua attività, per quanto sinora noto, si concentra prevalentemente a Palermo tra l’ultimo quarto del XV secolo e i primi decenni del XVI. New documents that have come to light on Antonio Belguardo allow us to draw a more complete biographic profile of one of the most prolific protagonists of Late Gothic Sicilian architecture; His activity, as far as we know, was mainly carried out in Palermo, between the las…
Principalis fabricator huius felicis urbis Panormi, in S. Montana, F. Scaduto, Antonio Belguardo a master of the late Gothic in Western Sicily and so…
2016
Le informazioni documentarie emerse in questi ultimi anni sulla figura professionale di Antonio Belguardo permettono di ricostruire una biografia attendibile e abbastanza completa di uno dei più importanti e dotati maestri dell’ultimo gotico in Sicilia occidentale e a Palermo, operante tra l’ultimo ventennio del Quattrocento e il primo Cinquecento. Il prestigio e il ruolo del maestro appaiono subito evidenti se si considerano l’intensa attività svolta, il successo presso una committenza “alta” e la rapida ascesa professionale e sociale comprovata dalla carica di capomastro regio (1536) e dalla carriera ecclesiastica del figlio Giovanni probabilmente identificabile con il vescovo di Telese, …
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…
'Aquarum deliciae' nei palazzi dei re normanni a Palermo
2022
Il lavoro illustra il forte legame esistente tra gli edifici dei re normanni a Palermo -in particolare i “sollatia”, in cui amavano rifugiarsi, con la loro corte, per cacciare e ripararsi dalla calura estiva, immersi nella rigogliosa vegetazione dei grandi parchi che dalla città si estendevano fino alle pendici della rocca di Monreale e su tutta la cosiddetta piana dei colli- e l’acqua. El estudio ilustra la fuerte nrelación entre los edificios de los reyes normandos en Palermo –en particolar los “sollatia”, en los cuales amaban refugiarse, con su corte, para cazar y reposar del calor estival, inmersos en la exhuberante vegetación de los grandes parques que desde la ciudad se extendían hast…
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…
Carbonates from the ancient world's longest aqueduct:A testament of Byzantine water management
2021
The fourth‐ and fifth‐century aqueduct system of Constantinople is, at 426 km, the longest water supply line of the ancient world. Carbonate deposits in the aqueduct system provide an archive of both archaeological developments and palaeo‐environmental conditions during the depositional period. The 246‐km‐long aqueduct line from the fourth century used springs from a small aquifer, whereas a 180‐km‐long fifth‐century extension to the west tapped a larger aquifer. Although historical records testify at least 700 years of aqueduct activity, carbonate deposits in the aqueduct system display less than 27 years of operation. This implies that the entire system must have been cleaned of carbonate…
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…
