In the first few decades of the seventeenth century countless songbooks were published in Italy, more than 300 of which included the notation system for guitar accompaniment known as alfabeto. This early repertoire for the five-course Spanish guitar was printed mostly in Naples, Rome, and Florence, and was a pivotal precursor to our modern tonal musical understanding. The very nature of both the instrument and its characteristic dance-song accompaniment style led composers to create block harmonies in diatonic progressions long before such concepts bore any semblance to a functioning theory. This paper uses the 1620 publication Arie a una voce by Roman composer Stefano Landi as a case study through which to examine the important roles that both alfabeto and the guitar played in the development of monody. The ongoing debates over the practicality, authorship, and interpretation of alfabeto notation are all addressed in reference to the six pieces marked “per la chitara Spag.” found near the end of Landi's first songbook. This will provide an understanding of the alfabeto notation system as well as the role of the guitar in the rise of monody, provide more specific answers concerning the viability of accompanying these specific songs on the guitar, and provide a means for constructing an informed interpretation and recording of these examples of a long-overlooked repertoire.

Fatique life extension of nuclear powerplants lies in the search for project reserves. This work deals with the evaluation of low-cycle fatigue of nuclear installations of the VVER type and the assessment of the influence of the computational model level. Fatigue tests of austenitic steel using optical method of digital image correlation for which the evaluation procedure is designed and used is performed. Selected model of plasticity with kimenatic (Chaboche) and combinated hardening (Chaboche, Voce) are calibrated from the obtained data. Subsequently, the durability of the test specimen is determined by computational modeling for different material models. From the comparison of the results of fatigue tests with the calculation, the material models suitable for the description of fatigue life and their validity are determined.

La tesi nasce dalla riflessione su un aspetto della fruizione dei Promessi sposi che rende il romanzo un unicum nella letteratura italiana: fin dai suoi esordi, il testo è stato letto ad alta voce e ascoltato nelle più svariate occasioni. Da qui l’idea di indagare se esistano, e quali siano, aspetti del testo che lo rendono particolarmente adatto all’ascolto. Conseguenza diretta dell’ascoltabilità del romanzo può essere, poi, la sua caratteristica memorabilità, grazie alla quale episodi e intere porzioni di testo si imprimono facilmente nella mente dei lettori-ascoltatori. La tesi si compone, dunque, di due sezioni, tra loro interconnesse, ma dedicate l’una, in modo più specifico, al primo aspetto in questione, l’ascoltabilità, l’altra al secondo, la memorabilità. Nel primo capitolo si pone l’attenzione sul rapporto tra I promessi sposi e la lettura ad alta voce; nel secondo capitolo l’analisi cerca di mettere in luce l’importanza del racconto orale (e dell’ascolto di narrazioni) nel romanzo; il capitolo terzo si concentra sulla ricerca delle caratteristiche (varietà e ripetizione) che rendono il romanzo memorabile a livello della sua struttura narrativa e delle connessioni tra le sue parti; il quarto e ultimo capitolo è dedicato ancora ai medesimi concetti, ma in questo caso l’analisi si focalizza sulle dimensioni morfo-sintattica e retorica del testo. / This thesis takes his origin from the reflection about a really singular feature that makes the novel I promessi sposi a unicum in italian literature. Since his first release, the text has been read aloud and listened in many and different occasions. Therefore, it has been tried to find the existence in the novel of some features that make it so suited to be listened to. A direct consequence of the novel's “listenability” is his typical “memorability”, that makes it really easy for the reader-listener to remember episodes and entire portions of the text. Thus, the thesis is composed of two sections, connected each other, but dedicated the one, in a more specific way, to the first feature at issue (“listenability”) and the other to the second (“memorability”).
