Viaggi nell’immaginario: il turismo virtuale nel sito UNESCO di Tarragona

2023

Le nuove tecnologie hanno trasformato in modo radicale non solo la geografia come disciplina, ma anche le geografie del mondo. Il digitale ha assunto, infatti, un ruolo di mediazione sempre più pervasivo nella produzione dello spazio, come delle conoscenze e degli immaginari geografici. Le possibilità offerte dal virtuale, in particolare, offrono oggi un contributo decisivo nella comunicazione dei significati attribuiti ai luoghi e rispondono in modo sempre più efficace ai bisogni emergenti del settore turistico. Le esperienze di visita mediate dal digitale mirano a coinvolgere i sensi e risultano efficaci quando promuovono immersioni rigorosamente realistiche. Nel quadro di queste riflessi…

New technologies have radically transformed not only geography as a discipline but also the geographies of the world. Indeed the digital has assumed an increasingly pervasive mediating role in the production of space as of geographic knowledge and imaginaries. The possibilities offered by the virtual in particular now offer a decisive contribution in communicating the meanings attributed to places and respond increasingly effectively to the emerging needs of the tourism sector. Digitally mediated visitor experiences aim to engage the senses and are effective when they promote rigorously realistic immersions. Within the framework of these reflections the paper highlights the renewed relevance of authenticity both of the tourism experience and of cultural heritage in relation to its potential for attraction and proposes a contextualization of the theme in light of the unprecedented opportunities granted by technologies for the creation of virtual and augmented spaces. The proposed discussion is therefore also a journey aimed at exploring authenticity as a tool through which new technologies can effectively mediate a sense of place and foster brand communication of a destination. The case study is the UNESCO site of Tarragona whose most relevant image for urban policies is presented. This shared figuration spatially defined and rooted in a precise historical moment is reconstructed on the one hand through the analysis of functional documentation for the candidacy and on the other by means of a review of mobile applications developed for the promotion of the city's cultural heritage. The proposed journey and exploration of the place return in light of the research data and in conclusion the central role played by digital technologies in mediating the UNESCO imaginary. The forms of virtual tourism in Tarragona confirm that to travel is to experience a text enveloped in time and inscribed in space.Settore M-GGR/01 - Geografia

Condition Assessment and Analysis of Bearing of Doubly Fed Wind Turbines Using Machine Learning Technique

2023

Condition monitoring of wind turbines is progressively increasing to maintain the continuity of clean energy supply to power grids. This issue is of great importance since it prevents wind turbines from failing and overheating, as most wind turbines with doubly fed induction generators (DFIG) are overheated due to faults in generator bearings. Bearing fault detection has become a main topic targeting the optimum operation, unscheduled downtime, and maintenance cost of turbine generators. Wind turbines are equipped with condition monitoring devices. However, effective and reliable fault detection still faces significant difficulties. As the majority of health monitoring techniques are primar…

Implementare il patrimonio archivistico: ricostruzione virtuale di una villa non realizzata di Giuseppe Samonà in Sicilia

2023

Questo saggio vuole essere una testimonianza dell’importanza culturale e cognitiva degli archivi (del progetto) intesi come patrimonio pubblico. L’azione di re-immaginarli può costituire un veicolo per la loro conoscenza? Con l’analisi di un caso-studio di un’abitazione non realizzata di un architetto del Novecento come Giuseppe Samonà si prova a verificare l’efficacia degli strumenti digitali per l’interpretazione dell’architettura come mezzi per l’implementazione comunicativa di un archivio.

Settore ICAR/17 - DisegnoThis essay is a testimony to the cultural and cognitive importance of (project) archives as public heritage. Can the action of re-imagining them be a vehicle for their knowledge? With the analysis of a case study of an unrealised house by a 20th century architect such as Giuseppe Samonà an attempt is made to verify the effectiveness of digital tools for the interpretation of architecture as a means for the communicative implementation of an archive.

A Proposal to estimate the roaming–dog Total in an urban area through a PPSWOR spatial sampling with sample size greater than two

2018

Settore SECS-S/05 - Statistica SocialeDogs roaming in urban areas constitute an issue for public order hygiene and health. Proper planning of actions for health and security control and allocation of financial funds require the knowledge of the roaming–dog–population size in a given urban area. Unfortunately a reliable statistical procedure aimed to measure such population is not available yet in literature. This paper presents a simple reproducible survey sampling procedure to estimate the number of roaming dogs in an urban area through the description of a real study carried out on a restricted area of the city of Palermo in southern Italy. A sample of areas is drawn by means of a drawn–by–drawn spatial sampling with probabilities proportional to size and without replacement (PPSWOR). As inclusion probabilities are not available in closed form they are estimated by Monte Carlo approach which is of simple implementation and permits design–based variance estimation even when first–order inclusion probabilities are unknown.

On new means with interesting practical applications: Generalized power means

2021

Means of positive numbers appear in many applications and have been a traditional matter of study. In this work, we focus on defining a new mean of two positive values with some properties which are essential in applications, ranging from subdivision and multiresolution schemes to the numerical solution of conservation laws. In particular, three main properties are crucial—in essence, the ideas of these properties are roughly the following: to stay close to the minimum of the two values when the two arguments are far away from each other, to be quite similar to the arithmetic mean of the two values when they are similar and to satisfy a Lipchitz condition. We present new means with these pr…

IL LEGISLATORE TEDESCO ALLARGA LE MAGLIE DELLA REVISIONE CONTRA REUM: L'ASSOLUZIONE PER DELITTI GRAVI E IMPRESCRITTIBILI PUÒ ESSERE MESSA IN DISCUSSI…

2022

Il legislatore tedesco ha ampliato il novero dei casi di revisione in peius. Ha previsto la possibilità di impugnare una sentenza definitiva di assoluzione per omicidio o crimini internazionali, qualora – in base a nuovi fatti o mezzi di prova – emergano “ragioni stringenti” per una condanna. La riforma ha già sollecitato dubbi di legittimità costituzionale e, per la sua rilevanza, suscita varie riflessioni.

The German legislator has enlarged the cases of in peius revision. It is now provided the possibility to challenge a final acquittal for murder or international crimes when “compelling grounds” for a conviction emerge on the basis of new facts or means of evidence. The reform has already posed doubts of constitutionality and due to its relevance raises various reflections.Settore IUS/16 - Diritto Processuale Penale

Pannello precompresso di vetromattoni assemblati a secco per la realizzazione di involucri traslucidi

2012

L’invenzione riguarda la realizzazione di un pannello di vetromattoni montati “a secco” -da impiegare per la realizzazione di involucri edilizi traslucidi anche nel caso di edifici alti- che è in grado di rispondere adeguatamente alle sollecitazioni orizzontali (quali quelle dovute a vento e sisma) grazie all’applicazione della tecnica della precompressione mondirezionale. Per offrire una risposta ai limiti imposti dalla tecnica di assemblaggio tradizionale dei vetromattoni (“ad umido”), l’applicazione della precompressione consente, infatti, di dare ai pannelli preassemblati “a secco” una rigidezza adeguata anche in direzione normale al loro piano di posa, sfruttando le buone caratteristic…

The invention is related to the construction of a glassblock panel “dry assembled” that can be used to build translucent building envelope even in high-rise buildings. This panel is able to contrast the horizontal actions due to wind and earthquake by means of the application of unidirectional pre-stressing technique. To overcame the limits due to the “wet assembly” system traditionally used to assemble the glassblocks the use of prestressing technique allow the panels to have an adequate mechanical resistance against the actions perpendicular to their installation plane. In this configuration the mechanical resistance of the glassblocks is exploited. The unidirectional prestressing (along the prevalent dimension of the panel) is obtained through the grip of the nuts inserted in the steel bars that are housed inside the glassblocks supporting profiles positioned in the vertical cavities between the glassblocks and passing through the horizontal profiles useful to separate glassblock rows from each other. The proper nuts grip opposing to the steel plates positioned at the top and bottom of the panel allow to prestress the panel. The steel plate are positioned on a plastic plate fixed to the lateral faces of the glassblocks by means of resins.Settore ICAR/10 - Architettura Tecnica

Abstract. Despite the availability of both commercial and open-source software, an ideal tool for digital rock physics analysis for accurate automatic image analysis at ambient computational performance is difficult to pinpoint. More often, image segmentation is driven manually, where the performance remains limited to two phases. Discrepancies due to artefacts cause inaccuracies in image analysis. To overcome these problems, we have developed CobWeb 1.0, which is automated and explicitly tailored for accurate greyscale (multiphase) image segmentation using unsupervised and supervised machine learning techniques. In this study, we demonstrate image segmentation using unsupervised machine le…

Ergonyms of Educational and Cultural spheres in two of Baltic States cities

2020

Daugavpils (Latvia) and Narva (Estonia) are cities in the Baltic States and signifi cant cultural and economic centres of their respective countries. These cities are characterized by a minority of nationals (19.8% of residents of Daugavpils are Latvian, 4% of residents of Narva are Estonian) and a similar linguistic situation: there is a dominance of Russian in the press, television and radio, but the state language prevails in the urban language signs.The aim of the study is to analyse the linguistic and extralinguistic means used for the creation of ergonyms of educational and cultural spheres. The main criteria for the analysis are: language choice, grammatical structures, sources of pr…

Los beneficios del mar: negocios e inversiones económicas de la oficialidad naval en el siglo XVIII

2019

Throughout the eighteenth century, the Spanish navy was extensively reformed and enhanced as a consequence of the new model of Monarchy that the Bourbons introduced. Among the measures adopted, it is remarkable the erection of the naval officers corps according to the needs and obligations that maritime war had in this century. This group becomes the paradigm of the new professionalization and new training approach, and its members had great relevance due to its great mobility around the empire and the power of the naval institution. This means that a part of the naval officers were placed in privileged positions and at the intersection of diverse political, social and economic networks. Th…
