Il primo concorso per il Palazzo di Giustizia a Roma del 1884. Ricostruzione critica del progetto di Ernesto Basile
2019
1. Breve descrizione dell’oggetto di studio Il concorso del Palazzo di Giustizia di Roma si svolge in quattro fasi svolte tra il 1884 e il 1887. Il progetto per il primo concorso, del 1884, redatto dall’allora giovanissimo Ernesto Basile (Palermo 1857-1932), rivela una grande perizia progettuale che trasforma il complesso programma funzionale in un austero edificio in stile neofiorentino. I disegni originari dell’opera, non realizzata, conservati presso la Dotazione Basile del Dipartimento di Architettura dell’Università di Palermo, sono stati oggetto di studio propedeutico alle fasi di analisi, interpretazione e ricostruzione congetturale del modello digitale. 2. Stato dell’arte e riferime…
The Formalisation of Water Use and Conditional Ownership in Colca Valley, Peru
2019
This article discusses the production and negotiation of water ownership among peasant farmers in the Majes-Colca watershed in southern Peru, where the public water administration initiated a process of formalising user rights for potable water in 2011. While a large-scale irrigation project channels water from the headwaters to export-oriented agriculture in the desert, the supply of water is getting scarcer because of climate change. The Peruvian water resources law from 2009 acknowledges water as public property, yet emphasises its economic value and encourages private investment. The farmers in the highlands see water not only as a resource but also as a lifegiving force provided by the…
Text Linguistics and Classical Studies: Dressler and de Beaugrande’s Procedural Approach
2017
The work represents a significant scientific advancement on text linguistics from three different viewpoints. The first chapter provides an overview of the history of text linguistics from a broader perspective than usual, offering a complete reference framework. The second chapter presents the procedural approach to the study of text linguistics in a concise way, including a critical comparison with other perspectives. The third chapter constructs a very unusual bridge between theoretical linguistics and classical studies in that it takes a literary text in Latin from the early imperial period as its case study. This combination is rare, as theoretical linguists are usually oriented to mod…
Thermal anomalies detection in a photovoltaic plant using artificial intelligence: Italy case studies
2021
This paper proposes the application of artificial intelligence techniques for the identification of thermal anomalies that occur in a photovoltaic system due to malfunctions or faults, with the aim to limit the energy production losses by detecting faults at an early stage. The proposed approach is based on a Thermographic Non-Destructive Test conducted with Unmanned Aerial Vehicles equipped with a thermal imaging camera, which allows the detection of abnormal operating conditions without interrupting the normal operation of the PV system rapidly and cost-effectively. The thermographic images and videos are automatically inspected using a Convolutional Neural Network, developed by an open-s…
The thermal performances of historic masonry: In-situ measurements of thermal conductance on calcarenite stone walls in Palermo
2018
Abstract Rich literature explores materials and construction techniques of historic buildings, but limited information is available about the thermal and hygrometric features of their envelope. Nevertheless, accurate hygrothermal data are essential for identifying effective energy upgrade measures, which must be compatible with the conservation of the architectural heritage. In order to fill this gap, it is necessary to refer to local contexts, where the variety of historic buildings is limited and their material and construction features are comparable. This paper focuses on historic masonry walls and discusses the results of twenty in-situ measurements of thermal conductance, performed al…
Interactive Tools for the Preservation, Dissemination and Study of Silk Heritage—An Introduction to the SILKNOW Project
2018
Silk was a major factor for progress in Europe, mostly along the Western Silk Road’s network of production and market centers. The silk trade also allowed for the exchange of ideas and innovations, having impacts at economic, technical, functional, cultural and symbolic levels. However, silk has today become a seriously endangered heritage. Although many European specialized museums are devoted to its preservation, they usually lack the size and resources to take advantage of state-of-the-art digital technologies. The aim of this paper is twofold; firstly, we introduce SILKNOW, an interdisciplinary project that has been recently funded by the H2020 Programme of the European Union in order t…
Evaluation of web reinforcements in prestressed concrete box girders through shear-transverse bending domains
2020
In concrete box girders, the amount and distribution of reinforcements in the webs have to be estimated considering the local effects due to eccentric external loads and cross-sectional distortion and not only the global effect due to the resultant forces of a longitudinal analysis: shear, torsion and bending. This work presents an analytical model that allows designers to take into account the interaction of all these effects, global and local, for the determination of the reinforcements. The model is based on the theory of stress fields and it has been compared to a 3D finite element analysis, in order to validate the interaction domains. The results show how the proposed analytical mode…

Il Paper presenta un'analisi delle performance delle imprese promosse dall'incubatore di imprese dell'Università di Palermo, fornendo un contributo al dibattito sulla "terza missione" dell'università e sulla creazione di condizioni favorevoli alla sua realizzazione.
Cuerpos de energía: Formas alternativas de ser-en-el-mundo
2020
Based on an ethnographic approach, this paper explores how members of a new age spiritual movement known as ?Llave Mariana? (LLM) build and experience their bodies. At the same time, it develops a thick description of their ritual practices and later it analyzes, delving fundamentally into the phenomenological perspective, how these members shape and transform their forms of self-perception, experience, and representation of others and the environment. Finally, it considers the implications these spiritual practices have in the search and consolidation of alternative ways of being-in-the-world
Overview of Power Electronic Switches: A Summary of the Past, State-of-the-Art and Illumination of the Future.
2020
As the need for green and effective utilization of energy continues to grow, the advancements in the energy and power electronics industry are constantly driven by this need, as both industries are intertwined for obvious reasons. The developments in the power electronics industry has over the years hinged on the progress of the semiconductor device industry. The semiconductor device industry could be said to be on the edge of a turn into a new era, a paradigm shift from the conventional silicon devices to the wide band gap semiconductor technologies. While a lot of work is being done in research and manufacturing sectors, it is important to look back at the past, evaluate the current progr…
