The use of subspace-based methods for damage detection in civili structures: a machine learning approach
Get PDFEvents in recent years have shown how important it is to monitor the structural health of existing civil works. Structural Health Monitoring systems are a useful tool to provide an objective and automatic valuation of the state of health of a structure, in order to detect the emergence of anomalies in its behavior. They are also an auxiliary tool in the decision-making phase for maintenance work or after extraordinary events. The Thesis work explores the topic of damage detection based on the analysis of subspaces of dynamical systems matrices. The aim of the research was to investigate a method for the development of levels in the damage diagnosis scale, ranging from the identification of the anomaly to the localization and subsequent assessment of the entity of the damage occurred. The study is carried out following two approaches: in the first, damage indices present in the literature are considered, and a newly developed one is presented. In the second approach, the identification issue is addressed by introducing the most recent Machine Learning tools: the goals are achieved through the supervised training of a classifier, with the task of localizing and quantifying the damage. In both cases, the methods used are model-driven type, based on simulations of the damage scenarios through Finite Element modeling. The thesis work therefore aimed to evaluate the effectiveness of the same subspace- based indices as objective functions in the optimization process related to the model updating process of the FE model, such that the simulated response in subsequent analyses would be as close as possible to the real one. The findings of the tests, both numerical and experimental, confirm the effectiveness of both proposed methods, highlighting their shortcomings and strengths. The concepts developed were subsequently applied to a case study, represented by the Basilica of Santa Maria di Collemaggio, in L'Aquila. In the first stage, the dynamic behavior of the Basilica was investigated, over the years of monitoring. Subsequently, traditional and Machine Learning algorithms have been implemented for the purpose of anomaly detection: the procedure has been performed considering as damaged a case, one produced after a structural intervention subsequent to the installation of the monitoring system. The studies on the Basilica showed a complex dynamic behavior, strongly influenced by environmental factors: nevertheless, the implemented algorithms proved to be effective for the defined purpose
Absurdist trends in american children's theatre : the case of "Noodle Doodle Box" by Paul Maar (1972) and "In a room somewhere" by Susan Zeder (1985)
Get PDFAnne Cirella-Urrutia evalúa el nacimiento del movimiento del absurdo en la historia del teatro juvenil americano. En particular, el artículo analiza el uso de técnicas del absurdo en las obras Noodle Doodle Box, escrita en 1972 por el dramaturgo alemán Paul Maar, y In a Room Somewhere, por la dramaturga americana Susan Zeder, actuada en 1985. La autora señala cómo estas obras adaptan fuentes familiares del Absurdo para ajustarse a su audiencia, con esta\ud
innovación estilística. Además, el artículo muestra los múltiples cambios temáticos, genéricos e interpretativos que Maar y Zeder ponen en acción para dirigirse a los niños
Cirella e il suo vino in un bando pontificio cinquecentesco
No full textPer secoli, il piccolo borgo calabrese di Cirella ha dato luce a un vino bianco dalle qualità così ricercate da aver incantato sovrani, viaggiatori ed accorti enologi. Il prezioso prodotto riusciva a giungere sulle migliori tavole, e cominciò ad essere oggetto di alterazioni fraudolente. Ciò bastò, nel Cinquecento, a innescare le ire di Papa Sisto V, che si spinse a emanare addirittura un bando contro coloro i quali mistificassero tale vino o lo vendessero mistificato. Le pene, tuttavia, furono talmente severe da aver causato, almeno in parte, il declino di quel vino, della sua produzione e della sua stessa esportazion
L’Astronomia a Napoli dal Settecento ai giorni nostri: storia di un’altra occasione perduta
Get PDFLa pubblicazione analizza le vicende dell'astronomia nel Mezzogiorno d'Italia, e soprattutto nella sua capitale, in un arco di tempo che parte dall'ascesa al trono di Carlo di Borbone e arriva sino ai giorni nostri. Una storia lunga e complessa, ricostruita attraverso il racconto delle biografie dei direttori che si succedettero alla guida dell'Osservatorio di Capodimonte, allo scopo di individuare i fattori socio-culturali che impedirono a Napoli e al Meridione in generale di partecipare agli sviluppi e ai successi che le scienze astronomiche stavano raggiungendo nelle altre regioni d'Europa
