Study and development of a web-based software for hybrid energy system design and solar prediction analysis
No full textLa sfida di integrare la potenza intermittente proveniente da fonti energetiche rinnovabili nella rete elettrica non può essere considerata come un problema isolato, ma deve essere vista come uno strumento per integrare e mettere in primo piano i sistemi energetici rinnovabili.
Questo progetto di tesi di dottorato presenta l'analisi, lo studio e lo sviluppo di un software ad interfaccia web in grado di progettare sistemi energetici ibridi in qualsiasi luogo del mondo, in grado di migliorare l'affidabilità, la disponibilità e la sostenibilità sia di sistemi connessi alla rete che di sistemi isolati.
Il software EHS (Energy Hybrid System) è stato sviluppato per ottenere la configurazione ottimale per varie tipologie di sistemi energetici ibridi. Lo studio della configurazione ottimale del sistema ibrido si basa sul valore del LCC (Life Cycle Cost) calcolato sulla durata potenziale dell'intero sistema considerando tutti i costi presenti e futuri.
La tesi presenta un caso di studio di progettazione, effettuata tramite software EHS, di un sistema energetico ibrido situato in Uganda. I risultati rivelano che la configurazione ottimale del sistema ibrido (generatori FV-baterie-diesel), nonostante il suo elevato costo di investimento, presenta un beneficio economico del 25,5 e del 22,2% rispetto all'utilizzo di solo FV e generatori diesel e solo generatori diesel e una riduzione del consumo di carburante pari rispettivamente al 74,7 e al 77%. Al fine di migliorare l'efficienza del sistema energetico ibrido, il progetto di tesi propone anche uno sviluppo di uno strumento in grado di fare una previsione affidabile della produzione fotovoltaica attraverso uno strumento sperimentale chiamato "predittore solare". In questo studio è stato utilizzato un sistema di acquisizione di immagini, basato su una fotocamera digitale commerciale, utilizzate per ottenere l'elaborazione delle immagini, rilevamento dei corpi nuvolosi, previsione del loro movimento e predizione dell’irraggiamento

Lo sguardo dello storico del'arte. Nikolaj Dmitrievič Protasov e le "Epistole dalla Puglia"
No full textIl saggio prende in esame la figura di Nikolaj Dmitrievič Protasov (1886-1940), storico erudito e archeologo proveniente da ambienti clericali, che giunge in Puglia nel 1914 in missione scientifica e di ricerca. Lo studioso, che indaga sul ruolo svolto dal monachesimo bizantino nei territori posti sotto la giurisdizione del Patriarcato Ecumenico di Costantinopoli (VIII-XI secolo) e su come la pittura russa antica potesse essere stata influenzata dalla pittura italiana medioevale, sarà completamente assorbito dalla scoperta delle chiese rupestri pugliesi e dalle raffigurazioni in esse presenti di San Nicola di Myra di cui darà accurata descrizione in Pis’ma iz Apulii (1914-1915). Prive degli artifici retorici della produzione memorialistica o diaristica, le epistole di Nikolaj Dmitrievič sono una chiara testimonianza di quanto l’Italia fosse terra di grande attrattiva presso i russi non solo per la ricchezza del patrimonio artistico e per le amenità paesaggistiche ma anche per il ruolo fondamentale che proprio la sua parte meridionale aveva avuto sin dai tempi della guerra greco-gotica (535-553). Nelle epistole di Protasov, testimonianza del viaggio da lui compiuto, ritroviamo gli echi di antichi conflitti, di persecuzioni, di ondate migratorie, delle comunità dei monaci greci e delle vite dei Santi pur nell’esattezza di un testo marcato da un’estrema precisione sensistica nella percezione dell’ambiente e composto nella rispettosa osservanza e applicazione pratica di quanto stabilito dall’autorità culturale che aveva determinato il passaggio dello studioso nel sud dell’Italia
Malfunction and Bad Behavior Diagnosis on Domestic Environment
No full textAbstractGreenhouse gas emissions from homes arise primarily from fossil fuels burned for heat, the use of products that contain greenhouse gases, and the handling of waste. Human activities are responsible for almost all of the increase in greenhouse gases in the atmosphere over the last 150 years. The household sector is one of the biggest aggregate consumers and this is the reason why increasingly policies have been considering it. One of the key factors in curbing energy consumption in this sector is widely recognized to be due to erroneous behaviors and systems malfunctioning, mainly explained by the lack of awareness of the final user; so, training the final user to energy awareness can be more effective and cheaper than other policies. In this context, energy management in homes is playing, and will play even more in future, a key role in increasing the final consumer awareness towards its own energy consumption and consequently in bursting its active role in smart grids. The aim of this paper is to highlight the economic benefits of low cost intelligent control domestic devices, to identify energy behavior, system status and improve energy efficiency. The scope is to develop interaction between final users to create a network of energy consumption efficiency. The paper presents an application of Multi-scale Principal Component Analysis to diagnose inefficient occupant behavior and systems malfunctioning and suggest good practices of energy conservation
Il reportage alla maniera di Tiziano Terzani: Buonanotte, Signor Lenin e le epifanie dei luoghi
No full textIn this paper, Gloria Politi embarks upon an analysis of Goodnight, Mister Lenin seen
as an interpretation of the genre of reportage in the peculiar way by its author Tiziano
Terzani. In terms of methodology, this approach draws on theories of literary criticism,
textual hermeneutics and narratology. The analysis shows how the depiction of the flow
of events before the reader’s eyes reveals an inner gaze that, according to Pavel Florensky,
almost creates a figurative mark, just like the impressions conveyed by poetry. Terzani’s
word thus expresses all its evocative potential as a narrative transfer of the rendering of
space in the visual arts
The cult of St Nicholas in medieval Italy
No full textSt Nicholas was one of the most popular saints in medieval Italy. His cult attracted the attention
of popes, kings and emperors, and his shrine at Bari became an important international pilgrimage
destination. This thesis asks how the cult of St Nicholas came to be so widespread and popular in
Italy, and why the saint attracted the attention of diverse groups and individuals.
This thesis is structured around four chapters. The first demonstrates that through a
process of Latinisation the cult of St Nicholas became integrated within Italian literary traditions
and within a new spiritual era. Chapter Two reveals that this Latinisation also occurred within the
saint’s iconography. Chapters Three and Four are case studies of the cult in Puglia and Venice,
locations which claimed possession of the saint’s relics. These case studies show that the general
developments that the cult of St Nicholas underwent in Italy, identified in Chapters One and Two,
did not apply universally. Instead, the presence of the saint’s relics resulted in a different profile
of the saint in Bari and Venice. Through the process of Latinisation, the cult of St Nicholas
became updated and remained relevant for its new Italian audience; Chapters Three and Four
show alternative ways that the cult of St Nicholas gained widespread popularity.
This thesis presents for the first time an iconographical study of St Nicholas in Italian art,
which develops existing research of the saint’s Byzantine iconography. Chapter Four presents a
profile of the cult of St Nicholas in Venice in the Middle Ages, which is a significant oversight in
the literature. The thesis uses a variety of visual and textual sources, in particular fresco and
altarpiece representations, archival documents from Venice and Rome (including the Apostolic
Visitations), and under-exploited contemporary and antiquarian Venetian sources

Lu Xun's Revolution : Writing in a Time of Violence /
No full textRecognized as modern China’s preeminent man of letters, Lu Xun (1881–1936) is revered as the nation’s conscience, a writer comparable to Shakespeare or Tolstoy. Gloria Davies’s vivid portrait gives readers a better sense of this influential author by situating the man Mao Zedong hailed as "the sage of modern China" in his turbulent time and place.Widely recognized as modern China’s preeminent man of letters, Lu Xun (1881–1936) is revered as the voice of a nation’s conscience, a writer comparable to Shakespeare and Tolstoy in stature and influence. Gloria Davies’s portrait now gives readers a better sense of this influential author by situating the man Mao Zedong hailed as "the sage of modern China" in his turbulent time and place. In Davies’s vivid rendering, we encounter a writer passionately engaged with the heady arguments and intrigues of a country on the eve of revolution. She traces political tensions in Lu Xun’s works which reflect the larger conflict in modern Chinese thought between egalitarian and authoritarian impulses. During the last phase of Lu Xun’s career, the so-called "years on the left," we see how fiercely he defended a literature in which the people would speak for themselves, and we come to understand why Lu Xun continues to inspire the debates shaping China today. Although Lu Xun was never a Communist, his legacy was fully enlisted to support the Party in the decades following his death. Far from the apologist of political violence portrayed by Maoist interpreters, however, Lu Xun emerges here as an energetic opponent of despotism, a humanist for whom empathy, not ideological zeal, was the key to achieving revolutionary ends. Limned with precision and insight, Lu Xun’s Revolution is a major contribution to the ongoing reappraisal of this foundational figure.Recognized as modern China’s preeminent man of letters, Lu Xun (1881–1936) is revered as the nation’s conscience, a writer comparable to Shakespeare or Tolstoy.
