Le Cinque giornate di Alfonso Litta Modignani
No full textLettura del diario (inedito fino a ora) di Alfonso Litta Modignani, protagonista delle Cinque giornate. L'analisi del testo definisce alcune strategie di scrittura prossime all'ambito manzoniano, particolarmente evidenti nel caso della descrizione della folla, tema tra i più interessanti nel dibattito storiografico della prima metà dell'Ottocento
Editorial Introduction to the Third Issue
No full textLinguistics had a strong presence at the TEI’s beginnings, being represented by names as significant as those of Nancy Ide, Donald E. Walker, and Antonio Zampolli. Linguistics was mentioned explicitly in the names of two of its three founding organizations: Association for Computers and the Humanities, Association for Computational Linguistics, and Association for Literary and Linguistic Computing. It was the main focus of one of the four initial committees (http://www.tei-c.org/Vault/AB/abj01.txt) and, within several years of the inception of the work on the TEI Guidelines, the British National Corpus clearly demonstrated the TEI’s usefulness for encoding language resources
Complex entity management through EATS: the case of the Gascon Rolls Project
No full textManaging entities like people, places and subjects across a large corpus of textual documents can be complicated. While the TEI guidelines offer a sound basis for the encoding of a great variety of textual material, there does not seem to be a general agreement on how to manage information that goes beyond the text, like entity information and relationships between entities
Optimization of a hydrogen compression and storage system for a green ammonia plant
No full textLAUREA MAGISTRALEL’urgente impegno globale verso la decarbonizzazione ha spinto l'idrogeno a porsi come candidato idoneo per molte applicazioni energetiche sostenibili. Oltre al suo promettente ruolo come vettore energetico, la sua importanza è particolarmente pronunciata in settori hard-to-abate come la produzione di ammoniaca e metanolo, che da soli coprono il 65% del consumo annuale di idrogeno. L’implementazione delle tecnologie dell'idrogeno green, tuttavia, dipende in modo critico dall'efficacia dei suoi sistemi di compressione e accumulo.
La presente tesi si propone di effettuare una revisione critica della letteratura esistente e delle informazioni commerciali relative alle tecnologie di stoccaggio e compressione dell'idrogeno. L'obiettivo primario è quello di valutare la maturità e l'applicabilità pratica di queste tecnologie nei vari casi d'uso previsti. Inoltre, questo studio cerca di identificare le correlazioni di costo, utilizzando metodologie di regressione lineare e power law, finalizzate a prevedere le spese relative ai sistemi di compressione e accumulo dell'idrogeno.
Il lavoro di tesi ha inoltre lo scopo di sviluppare un modello in grado di valutare il reale impatto delle tecnologie di compressione, in particolare sugli impianti di ammoniaca verde. Questo sforzo comporta lo sviluppo di un algoritmo di ottimizzazione MILP, per la determinazione del design ottimale del sistema di accumulo e compressione, considerandone il funzionamento annuale, con la sfida di dover linearizzare la descrizione di un processo fortemente non lineare. Questo sforzo è fondamentale per superare l'assunto diffuso dell'impatto trascurabile dei sistemi di compressione dell'idrogeno nella progettazione di impianti industriali “verdi”, comune a molti studi.The pressing global effort toward decarbonization has propelled hydrogen to the forefront as a main candidate for sustainable energy solutions. In addition to its promising role as an energy carrier, its significance is particularly pronounced in hard-to-abate sectors like ammonia and methanol production, that by themselves cover 65% of the yearly hydrogen consumption. The potential of hydrogen, however, critically hinges on the effectiveness of its compression and storage systems, pivotal components within green energy frameworks.
This paper embarks on a critical review of extant literature and commercial information surrounding hydrogen storage and compression technologies. The primary objective is to assess the maturity and practical applicability of these technologies across various envisioned use cases. Furthermore, this study endeavors to establish robust cost correlations, utilizing linear and power-law regression methodologies, aimed at predicting expenses pertinent to prevalent hydrogen compression and storage systems.
Furthermore, the thesis endeavors to develop a comprehensive model capable of assessing the true impact of compression technologies specifically on green ammonia plants. This endeavour involves developing a robust MILP optimization algorithm, for the determination of the conceptual design of the storage and compression system optimizing the operation over a year, overcoming the difficulty to linearize a strongly non-linear process. This effort is critical to challenge the prevailing assumption of the negligible impact of hydrogen compression systems in the optimization of green plants, common to several academic works, despite the high operational and investment cost of compressors
What We Talk about When We Talk about Paradigms: Representing Latin Word Formation
No full textWord and Paradigm approaches to derivational morphology have been increasingly discussed in the last three decades (since Bauer 1997, but also Jackendoff 1975). However, notwithstanding the many examples of the evidence of paradigmatic derivation described in Štekauer 2014, it is still not clear whether it is possible to envisage larger, all-embracing paradigms. These would be essential to both deeply account for and predict recurrent patterns in a language.
In our work, we are employing data contained in the Word Formation Latin (WFL) lexicon (Litta et al. 2016) to determine what need to be the main requirements for the physical representation of a derivational paradigm. The method employed to build the WFL lexicon has raised a number of problems (Budassi & Litta 2017): derivational families are represented via tree-graphs, and word formation rules are modelled as directed one-to-many input-output relations between lexemes. On the other hand, the WFL database contains relevant information on all derivational patterns in Latin, which makes it a precious source of data for our purposes.
We decided to represent the paradigm in the shape of a table, highlighting the importance of the “cell”. In addition, we adopted aspects of Construction Morphology (CxM, Booij 2010) in order to add information to the cell. The system is thus enhanced with both morphological and semantic information.
In this paper, we are going to explain which concepts borrowed from CxM suit the description of the function of a paradigm cell, and which ones we need to forgo in order to account for Latin's variety of development throughout time and space
CYBRD1 as a modifier gene that modulates iron phenotype in HFEp.c282y homozygous patients.
No full textBackground. Most patients with Hereditary Hemochromatosis are homozygous for the p.C282Y mutation in the HFE gene in Caucasian population. Penetrance and expression of Hemochromatosis largely differ in p.C282Y homozygous cases. Besides environmental factors, genetic factors might be implicated. Design and Methods. In the present study, we analysed 50 candidate genes involved in iron metabolism and evaluated the association between 214 single nucleotide polymorphisms in these genes and three phenotypic outcomes of iron overload (serum ferritin, iron removed and transferrin saturation) in a large group of 296 Italian p.C282Y homozygous cases. Polymorphisms were tested for genetic association with each single outcome using linear regression models adjusted for age, sex and alcohol consumption. Results. We found a series of 17 genetic variants located in different genes with possible additive effect on the studied outcomes. In order to evaluate if the selected polymorphisms could provide a predictive signature for adverse phenotype, we re-evaluated data by dividing patients in two extreme phenotype classes based on the three phenotypic outcomes. We found that only a small improvement in prediction can be achieved adding genetic information to clinical data. Among the selected polymorphisms, a significant association between rs3806562, located in the 5'UTR of CYBRD1, and transferrin saturation was observed. This variant belongs to the same haplotype block which contains the CYBRD1 polymorphism rs884409, found to be associated with serum ferritin in another population of p.C282Y homozygotes, and able to modulate promoter activity. Luciferase assay indicates that rs3806562 has not a significant functional role, suggesting that it is a genetic marker linked to the putative genetic modifier rs884409. Conclusions. While our results support the hypothesis that polymorphisms in genes regulating iron metabolism may modulate penetrance of HFE-HH, with emphasis on CYBRD1, they strengthen the notion that none of these polymorphisms alone is a major modifier of HH phenotype
The Two Approaches to Word Formation in the LiLa Knowledge Base of Latin Resources
No full textIn this paper, we propose a model to include a derivational lexicon for Latin (Word Formation
Latin) within the LiLa Knowledge Base of interlinked linguistic resources for Latin. After a brief
introduction on the architecture of LiLa, we discuss the differences between the flat organization of
derivational information in LiLa’s Lemma Bank and the hierarchical structure ofWord Formation
Latin, showing that the latter contains potentially useful information that is not already available
in the former. We describe the modelling of such information in LiLa, exemplifying how different
word formation processes are treated. We conclude the paper by showing the complementarity
of the two approaches, and outlining the advantages offered by their interconnection
