Seismic response of large offshore wind turbines on monopile foundations including dynamic soil–structure interaction
No full textThis paper presents the results of a study on the dynamic and seismic response of the support structures of
three reference Offshore Wind Turbines (OWT) of increasing rated power, founded to the seabed through
monopile foundations. Thus, the structural behaviour of the NREL 5 MW, IEA Wind 10 MW and IEA Wind
15 MW reference OWTs under seismic input is analysed. To do so, a model based on the aero-hydro-servo-
elastic OpenFAST open-software code, modified to include dynamic Soil–Structure Interaction (SSI) and input
ground motion, is employed. Dynamic SSI phenomena are incorporated through lumped parameter models
fitted to the impedances computed using an advanced boundary elements–finite elements model of the soil–
foundation system in which the monopile is discretized as a steel pipe buried in the unbounded seabed. The
fore–aft and side-to-side responses of the systems are computed under power production, parked and emergency
shutdown operating conditions considering different earthquakes and arrival times. It is found that even low
and moderate intensity earthquakes can produce significant increases in the structural demands of large OWTs.
There exists a clear tendency for SSI to be beneficial when the size of the OWT increases
Una guerra identitaria. La ricezione del passato greco-romano nel colonialismo italiano
No full textIl 26 novembre 1911, presso il teatro di Barga, Giovanni Pascoli incitò alla guerra di Libia descrivendo la regione nordafricana come «abbondevole d’acque e di messi, e verdeggiante d’alberi e giardini», ma anche ricca di monumenti antichi, talmente numerosi da far dire al poeta: «Anche là è Roma!». Come in molti altri momenti dell’itinerario coloniale italiano, il Classico divenne allora mito di legittimazione da utilizzare per presentare guerre di conquista come missioni di civiltà, rivolte verso popoli ritenuti barbari e senza storia. Gli antichisti contribuirono in misura considerevole allo sviluppo di tali rappresentazioni, alleandosi con politici, militari e colti dilettanti in una storia di lungo periodo qui ripercorsa attraverso alcune date, luoghi e personaggi fondamentali; fra il 1887 e il 1977, fra Dogali e Roma, fra De Sanctis e Wilamowitz. Ma il cammino fu sempre così chiaro o ci fu anche chi cercò percorsi alternativi? Il Classico, del resto, è mito ambiguo, che da strumento di sostegno al potere può anche diventare sferzante mezzo di critic

No full textThis study aims to deepen our knowledge of the Innovative Start Ups (ISUs) ‘human’ role within open innovation (OI) adoption. To achieve this, we explore how the ISU leader, namely the founder/CEO managerial characteristics influence the ISUs open innovation adoption dynamics (i.e. mechanisms, partners, motives and sequence of adoption). The empirical analysis is based on a sample of innovative startups belonging to San Marino Innovation, the institution that in the Republic of San Marino deals with the promotion and support of the development of innovative startups with international growth ambitions. Starting from recognizing the centrality of the ISU founder/CEO as a pivotal decision maker, asking if, when, who and how to engage in OI, this research seeks to explore the main entrepreneurial founder/CEO managerial characteristics and the influence these characteristics have on the OI adoption dynamics within the ISU. Our findings demonstrate that ISU open innovation adoption is project based: they develop open innovation capabilities on a "project by project basis" and mature as a consequence, thus highlighting the importance of the ‘doing, using, interacting’ mode of learning within ISU OI development.

A Reading-Free Screening Tool: testare le abilità cognitive sottostanti la dislessia per identificare le difficoltà di lettura in bambini monolingue e bilingue
No full textAd oggi non sono disponibili strumenti ad-hoc per la valutazione dell’apprendimento di studenti con contesto familiare straniero (Minority Language Children - MLC), ma si fa piuttosto riferimento ai test di lettura standardizzati sulla popolazione monolingue italiana. Ciò pone il dubbio che le difficoltà di lettura osservate sui MLC1,2 siano dovute alla minore esposizione all’italiano, piuttosto che alla dislessia evolutiva (DE).
Pertanto, è stato sviluppato una nuova batteria “Reading-Free Screening Tool” per lo screening delle difficoltà di lettura su lettori monolingue e MLC. Lo strumento, costituito da una serie di compiti cognitivi non verbali, è stato somministrato a 142 studenti monolingue (107 buoni lettori; 35 con difficoltà di lettura) e 68 MLC tra gli 8 e i 13 anni.
Le prestazioni dei monolingui nei compiti sperimentali hanno contribuito ad addestrare un algoritmo di classificazione (CART model), successivamente applicato agli MLC.
Lo strumento ha un’accuratezza diagnostica dell’86% sui monolingui. Quando applicate agli studenti bilingue, le regole di classificazione hanno identificato come buoni lettori 11 dei 16 lettori con difficoltà identificati tramite i test di lettura. Tali risultati, supportando l’idea che una valutazione basata su test di lettura standardizzati sui monolingui possa generare errate diagnosi su una buona parte di MLC

Sustainability and Open Innovation: Main Themes and Research Trajectories
No full textToday, innovation and sustainability in their broadest sense, which includes people (social dimension), the planet (environmental dimension) and profits (economic dimension), are increasingly intertwined. Integrating the sustainability dimension into the innovation of products, services, processes, technologies, business and organizational models requires an effort on the part of the company as it demands a different set of knowledge and skills than those needed to innovate in a traditional way. As a result, companies, in order to integrate the dimension of sustainability in their innovation processes, have felt the need to exploit knowledge, skills and technologies external to the organization itself, promoting what is called the process of open innovation. Since this field of field is only recently being explored, we conducted a literature review through bibliometric analysis on a sample of 93 scientific articles published between 2011 and today, April 2022. To achieve the purpose of this review, both quantitative (co-occurrence analysis) and qualitative analysis have been conducted. Four different research themes have been identified: sustainable open innovation and innovation performance, the role of technological capability for sustainable open innovation, business model perspective and sustainable open innovation and university collaboration. As far as future research is concerned, a mainline has been identified concerning the study of sustainable open innovation in the agri-food industry

Design Elements for the Implementation of Threshold Crossing In and Out of Mixed Reality
No full textThe chapter presents research on the relationship between the human body and the space implemented by data and digital interfaces. In this relationship, technology plays a mediating role. The research introduces the concept of a digital threshold to an interactive space that has the capacity to preserve the cognitive well-being of users and invite interaction. To do this, some characteristics are identified that can be used in the design with the aim of relating the body to the devices in the space. Pressure stimuli, rhythm, and body symmetry are the components of a natural language capable of activating a natural motorial reaction mechanism. The details of the experimentation carried out and the processing of the data collected through data visualisation are provided to support the argument
