Reading the Transformations of an Urban Edge: From Liberty Era Palermo to the City of Today
2019
To honour the battle of 27 May 1860, in 1910 the Palermo City Government decided to realise a commemorative monument. A position at the centre of a large circular plaza was of have afforded the monument a greater solemnity. The commission for the Monument was awarded to Ernesto Basile. In 1927 the City Government decided to dedicate the monument to the Fallen and asked Basile to complete the monument adding an architectural backdrop. The first version of the new project was a fence that enveloped the entire square and the ring road, interrupted only by entrances near the streets flowing into the square, and dividing it into four sectors. The final design instead called for the realisation o…
Identification of an LPS-Induced Chemo-Attractive Peptide from Ciona robusta
2020
Background: Previously published work has demonstrated that the LPS injection of Ciona robusta leads to the overexpression of a truncated form of an immune-related mRNA (C8short) by means of Ciona robusta (CR) alternative polyadenylation (APA) (CR-APA). Methods: The 3D structure of the C8short-derived Ciona robusta chemo-attractive peptide (CrCP) was evaluated by homology modeling. The biological activity of the CrCP was studied in vitro using a primary human dermal cell line (HuDe). Real-Time PCR was used to investigate the expression levels of genes involved in cell motility.

Structure Monitoring with BIM and IoT: The Case Study of a Bridge Beam Model
2022
The diffusion of Building Information Modelling (BIM) as a reference methodology, applied to the world of construction, leads to important changes in the design and the management of big constructions and infrastructures. However, although the BIM approach is necessary for managing the entire life cycle of a construction, today, this methodology is still rarely adopted beyond the design phase. This represents a major flaw because the management of every phase of the life cycle of buildings needs accurate preliminary planning. Certainly, one of the most complex and important phases of the life cycle of a construction is the monitoring phase, which represents a fundamental aspect for the main…
Il Portico meridionale della Cattedrale di Palermo: sperimentazioni di rilievo attraverso l’utilizzo di tecniche Structure from Motion
2014
Structure from Motion (SfM) techniques constitute a very fertile field of investigation within the research of the surveying sector and that of the representation of architecture. They allow us to reach higher levels of reliability and accuracy, both metric and graphical, extremely quickly and with lower costs than other methods, including the laser scanner. In this study, we report the results of some experiments carried out on the southern Portico entrance of the Cathedral of Palermo through the use of the SfM techniques later validated by comparison with the point cloud obtained from laser scanning.
Integration of terrestrial laser scanning and UAV-SFM technique to generate a detailed 3D textured model of a heritage building
2020
The digital twin is among the Top 10 of the strategic technological trends for the period 2007-2019, and it represents a powerful tool for the conservation and enhancement of cultural heritage. It reproduces with "precision" a physical asset, thus allowing to investigate its structure and to analyze the deformations that occur over the years. Various techniques have been introduced to obtain high-resolution 3D models. Among these, the Terrestrial Laser Scanner (TLS) is widely recognized as the gold standard to generate accurate 3D metric reconstructions. TLS allows acquiring a lot of data (point cloud) in a fast way, being not in physical contact with the objects of investigation. By integr…
Drawing space in the places of myth: Luigi Moretti and Sicily
2021
Come si disegnava l’architettura negli anni ’30? È questo il quesito di partenza attraverso cui si vuole imbastire una più ampia riflessione sull’architettura di quel periodo, assumendo come riferimento un progetto siciliano di Luigi Moretti: la Casa del Balilla di Messina del 1936. L’analisi iniziale del corpus delle tavole di progetto dell’edificio ha preventivamente lo scopo di valutare i contenuti espressivi del disegno inteso come strumento disciplinare proprio dell’architettura. Ma il fatto che l’opera prima di Luigi Moretti in terra di Sicilia non abbia mai visto la luce ha altresì indotto all’elaborazione di un’esegesi ulteriore, consistente nella costruzione di un modello tridimens…
Crowdsourcing Cultural Heritage: From 3D Modeling to the Engagement of Young Generations
2016
Monitoring, digitizing and archiving museum artworks represent an important socio-cultural accomplishment and an overcoming in digital preservation today. Cultural heritage is constantly under threat of terrorist attacks and natural disaster. The high costs related to documentation task have prevented a constantly and massive survey activity. The low cost 3D image based acquisition and elaboration techniques of an object, allow to carry out a 3D photorealistic model in a short time. Therefore, a lot of museum adopted these techniques for the artworks archiving. Crowdsourcing activities can significantly speed up survey and elaboration procedures. If, on the one hand, these initiatives can h…
Low cost system for visualization and exhibition of pottery finds in archeological museums
2015
The objective of this project is to build a low-cost system for surveying, modeling, prototyping and interactive visualizing aimed at the enhancement of islamic pottery finds of X – XI centuries. The system will allow various applications: the creation of systems for displaying artifacts from the museum alongside the exhibition, the virtual view of restorations from fragments, including AR and VR, the physical reconstruction of the original form using 3D printer to show the pieces in their entirety, as well as the construction of interactive virtual archives to be made available to scholars and visitors.
The Human Biodiversity in the Middle of the Mediterranean. Study of native and settlers populations on the Sicilian context
2020
[IT] Negli ultimi 200.000 anni, la specie umana si è diffusa in tutta la Terra, adattando la sua morfologia e fisiologia a un'ampia gamma di habitat. Lo scheletro umano ha quindi registrato i principali effetti ambientali e di conseguenza i reperti scheletrici assumono grande importanza nell'indagine dei processi evolutivi. Oggi le moderne tecniche di indagini quantitative delle principali caratteristiche morfologiche consentono di metterle in relazione con la variabilità genetica. La posizione geografica della Sicilia, l'isolamento e la sua lunga e dinamica storia di colonizzazione (diversi e numerosi contributi culturali e biologici) hanno creato un contesto peculiare che consente uno stu…
A 3D reworking of the urban transformations of Palermo in recent history for a hypothesis of a "City Museum" based on digital visualizations
2021
The objective that drives this research is given by a multitude of information which, in addition to the contribution of technology, allows us to study, analyze, verify and remodel the sites, monuments and evolutions of the city through graphic processes of perspective restitution that start from the analysis of historical photos. The drawing methods, the digital graphic rendering and through the aid of geometric techniques, contribute to the reconstruction of projects and architectures that are now lost, this is possible thanks to the methods of perspective, axonometry and three-dimensional restitution. This remarkable photographic heritage belonging to Palermo, but also to any other city …
