Operational profiles data analytics for ship design improvement
No full textThe main purpose of thiswork is to build a data driven model to create realistic operating profiles in order to assess and compare different design solutions. The proposed approach takes advantage on the new generation of automation systems which allow gathering a large amount of data from on-board machinery. Data driven models are built upon statistical inference procedures based on the historical data collection. The advantage of these methods is that there is no need of any a-priory knowledge of the underlying physical system. Furthermore, thanks to the nature of these approaches, it is possible to exploit even data from sensors that could contain some kind of hidden information that cannot be easily extracted with a parametric approach. The use of these tools is nowadays made possible since such information is digitally available from different sources: (i) data stored on board of vessels; (ii) Automatic Identification System (AIS) data available through the internet. A data driven modelling of the operational profiles of the vessel (and in general of the fleet) could provide a tool both to diagnose and predict the vesselâs state (e.g. for condition based maintenance purposes), for improving the performance and the efficiency of the vessel, and for improving design solutions. The diagnosis and prognosis of the shipâs performance can be used as decision support in determining when actions to improve performance should be taken. The developed model will be tested on a real DAMEN vessel where on-board sensors data acquisitions are available from the automation system

The genetic distance between <i>E. cryptica</i> <b>sp. n.</b> with other species (i.e. <i>E. buqueti</i>, <i>E. intermedia</i> and <i>E. speciosa oscuripennis</i>) was greater than 4.6% and statistically significant (see Table 2.). According with the NJ tree and p-distances, <i>E. cryptica</i> <b>sp. n.</b>, <i>E. buqueti</i> and <i>E. speciosa oscuripennis</i> exhibited similar genetic distances amongst them (4.2% to 5.4%) and low intraspecific genetic variability (0.3% to 0.8%) while <i>E. intermedia</i> showed higher values of both p-distance and genetic variability (Fig. 1 C).</p> <p> <b>Etymology.</b> The specific epithet “ cryptica ”, is an adjective, feminine that refers to the Greek word <i>kryptikos</i> that means hidden or enigmatic, because the species was not recognized and classified as <i>E. buqueti</i>.</p> <p> <b>Distribution and Bionomy.</b> Chile, Maule and Bio Bio regions: Curicó, Talca, Linares, Ñuble, Biobío, Concepción and Arauco provinces (Fig. 2 A). Foothills of the Andes Range and Coast Range in Concepción and Arauco provinces, close to the 1000 meters in environments with open xerophytic scrublands (Fig. 2 B). The adults were found associated with <i>Colletia spinossisima</i> and <i>C. hystrix</i> (Rhamnaceae) (Fig. 2 C).</p>Published as part of <i>Anguita-Salinas, Simón, Barahona-Segovia, Rodrigo M., Poulin, Elie & Zúñiga-Reinoso, Alvaro, 2017, Genetic and morphological evidence for a new cryptic species of Ectinogonia (Coleoptera: Buprestidae) from central Chile, pp. 284-292 in Zootaxa 4303 (2)</i> on pages 286-289, DOI: 10.11646/zootaxa.4303.2.8, <a href="http://zenodo.org/record/840968">http://zenodo.org/record/840968</a>
Music, Religious Communities, and the Urban Dimension: Sound Experiences in Palermo in the Sixteenth and Seventeenth Centuries
No full textNegli ultimi anni la ricerca musicologica ha rinnovato il proprio interesse nei confronti delle istituzioni musicali palermitane, sottolineando l'importanza della ricerca d'archivio per condurre a una ricostruzione del modo concreto in cui la musica risuonava in un contesto specifico. Questo approccio parte da una visione che considera l'elemento musicale quale componente essenziale dell'esperienza urbana, secondo i modelli della cosiddetta 'Urban Musicology' che riconosce la funzione svolta da tutti i luoghi di un dato spazio, non soltanto dalle grandi chiese con le loro cappelle musicali, ma anche dalle istituzioni meno in vista. In questa prospettiva occorre considerare il concetto di “suono” in senso più ampio. L'approccio urbano permette infatti di comprendere la ricchezza di un paesaggio sonoro variamente formato da voci, strumenti, campane e rumori che caratterizzavano gli eventi pubblici in Sicilia. Attraverso la componente sonora, le congregazioni religiose più rilevanti si imponevano nello scenario urbano, permeando il territorio con frequenti esibizioni e spesso entrando in competizione per il controllo dello spazio anche sul piano musicale. L'obiettivo di questo contributo è quello di fornire una panoramica della vita musicale palermitana tra Cinque e Seicento, soffermandosi in particolare sulle chiese monastiche e sottolineando il contributo musicale di quest'ultime alle più importanti cerimonie all'aperto.In the last years, musicological scholarship has renewed its interest in the musical institutions of Palermo, pointing out the importance of archive research leading to a reconstruction of the actual sound of sacred music in a specific context. This method starts from a vision that considers music as an essential component of the urban experience, according to the models of the so-called Urban Musicology, and recognizes the role played by all the sites in a given space, not only the major churches with their cappelle musicali, but also other lesser-known institutions. In this perspective, we need to consider the concept of ‘sound’ in a wider sense. The urban approach, indeed, allows us to understand the richness of a soundscape variously formed by voices, instruments, bells and noises, which characterized public events in Sicily. Through the sound element, the most relevant religious congregations imposed themselves in the urban scenery, permeating the territory with frequent performances and often competing to control the space at the musical level. The goal of this essay is to provide a panoramic view of musical life in Palermo between the sixteenth and the seventeenth centuries, focusing particularly on monastic churches and stressing their musical contribution to the most solemn open-air ceremonies
Shaping the Urban Soundscape in Spanish Palermo
No full textMy research focuses mainly on official music making, that is promoted by the politic and religious power, in Palermo in the age of the Spanish domination.
What I discuss in my chapter, is: 1) how music contributed specifically to shape the urban space, 2) which was the relation between musical experience and political power during the Spanish domination.
I will focus on the second half of the seventeenth-century, the final years of the Spanish rule. In this period of time, two important events marked the musical shaping of the urban space: 1) in 1682, the creation of a permanent venue for performing music “en plein air”, the so-called “teatro della musica” in the Strata Colonna; 2) in 1693, the construction of the first Opera theater, the Santa Cecilia theater in the area called the Fieravecchia.
Both facts had a great impact on the urban soundscape under different aspects that I discuss.
I also discuss the use of visual sources and their meaning for urban musicologists; moreover, I make reference to ways of listening to music in Baroque Palermo
