Compatibilità aeronautica. Definizione dei vincoli fisici per le aree limitrofe all'Aeroporto "G. Marconi" di Bologna

Per garantire la sicurezza di tutte le operazioni in volo (avvicinamento, decollo, holding, ecc..) il decreto legge del 15 marzo del 2006 n. 151 ha imposto la redazione di opportune cartografie basate sul Regolamento ENAC per la Costruzione e l’Esercizio degli Aeroporti e sulla normativa internazionale ICAO così da poterle annettere agli Strumenti Urbanistici del territorio e governare lo sviluppo delle costruzioni. La sicurezza delle operazioni in volo è garantita attraverso delle Superfici di Delimitazione Ostacoli che impongono dei vincoli plano-altimetrici nelle aree limitrofe agli Aeroporti, quindi costruzioni, alberi e lo stesso terreno non devono forare queste superfici altrimenti diventerebbero “Ostacoli” alla navigazione aerea. Per gli ostacoli già presenti sono definiti dei provvedimenti da adottarsi in funzione della superficie che questi forano: potranno essere abbattuti se ricadenti in aree critiche come in prossimità delle piste oppure essere segnalati in mappe in uso ai piloti e anche con segnali visivi posizionati sugli stessi. Per quanto riguarda le future costruzioni, queste non potranno mai diventare Ostacolo in quanto sarà obbligatorio rispettare i vincoli plano-altimetrici. La tesi di laurea in questione vuole illustrare come si è arrivati alla redazione delle sopraccitate mappe nel caso specifico dell'Aeroporto Guglielmo Marconi di Bologna; sono analizzate nel primo capitolo le caratteristiche fisiche degli Aeroporti per acquisire una certa padronanza su termini tecnici che compaiono nei capitoli successivi (è inoltre presente un glossario). Nel secondo capitolo è individuato il percorso normativo che ha portato alla redazione dell’ultima revisione al Codice della Navigazione. Il capitolo 3 introduce le superfici di delimitazione ostacoli secondo quanto esposto nel Regolamento per la Costruzione e l’Esercizio degli Aeroporti di ENAC; il capitolo 4 è dedicato al lay-out dell’Aeroporto Guglielmo Marconi di Bologna. Infine la tesi si conclude con il capitoli 5 nel quale sono esposte le fasi e le metodologie usate per la realizzazione delle planimetrie e con il capitolo 6 in cui si discute delle problematiche sorte a causa dell’orografia del territorio che deve tenersi nella giusta considerazione per la definizione dei suddetti vincoli aeronautici.

Strumenti per la valutazione dello stato conservativo e per la manutenzione programmata dei ponti della Provincia di Bologna

La tesi tratta di strumenti finalizzati alla valutazione dello stato conservativo e di supporto all'attività di manutenzione dei ponti, dai più generali Bridge Management Systems ai Sistemi di Valutazione Numerica della Condizione strutturale. Viene proposto uno strumento originale con cui classificare i ponti attraverso un Indice di Valutazione Complessiva e grazie ad esso stabilire le priorità d'intervento. Si tara lo strumento sul caso pratico di alcuni ponti della Provincia di Bologna. Su un ponte in particolare viene realizzato un approfondimento specifico sulla determinazione approssimata dei periodi propri delle strutture da ponte. Si effettua un confronto dei risultati di alcune modellazioni semplificate in riferimento a modellazioni dettagliate e risultati sperimentali.

Le Antichità di Bologna di Bartolomeo della Pugliola

For a long time, the work of a Franciscan Friar who had lived in Bologna and in Florence during the 13th and 14th centuries, Bartolomeo Della Pugliola, was thought to have been lost. Recent paleographic research, however, has affirmed that most of Della Pugliola’s work, although mixed into other authors, is contained in two manuscripts (1994 and 3843), currently kept at University Library in Bologna. Pugliola’s chronicle is central to Bolognese medieval literature, not only because it was the privileged source for the important work of Ramponis’ chronicle, but also because Bartolomeo della Pugliola’s sources are several significant works such as Jacopo Bianchetti’s lost writings and Pietro and Floriano Villolas’ chronicle (1163-1372). Ongoing historical studies and recent discoveries enabled me to reconstruct the historical chronology of Pugliola’s work as well as the Bolognese language between the 13th and 14th century The original purpose of my research was to add a linguistic commentary to the edition of the text in order to fill the gaps in medieval Bolognese language studies. In addition to being a reliable source, Pugliola’s chronicle was widely disseminated and became a sort of vulgate. The tradition of chronicle, through collation, allows the study of the language from a diachronic point of view. I therefore described all the linguistics phenomena related to phonetics, morphology and syntax in Pugliola’s text and I compared these results with variants in Villola’s and Ramponis’ chronicles. I also did likewise with another chronicle by a 16th century merchant, Friano Ubaldini, that I edited. This supplement helped to complete the Bolognese language outline from the 13th to the 16th century. In order to analize the data that I collected, I tried to approach them from a sociolinguistic point of view because each author represents a different variant of the language: closer to a scripta and the Florentine the language used by Pugliola, closer to the dialect spoken in Bologna the language used by Ubaldini. Differencies in handwriting especially show the models the authors try to reproduce or imitate. The glossary I added at the end of this study can help to understand these nuances with a number of examples.

L’emergere del periurbano: il caso di Bologna

The rationale behind this piece of research is to study the movement of people from Bologna city centre to its outskirts and to find out what type of people are subject to move and the reasons for this: are they forced into or do they choose to do so? The present study will also consider how people commute from home to the city centre and the effect this has on them. For the purpose of this work, attention will be drawn to the possibility of these outer areas to develop in such a way that people will no longer need to commute to the city in order to recreate the advantages this offers to them (e.g. shops, job opportunities, ext). The theoretical framework this doctorial work is based upon concerns historical, urbanist, sociological and demographic approaches, along with the fact that the hegemony of the city centre has been benefiting has decreased. Historical centres and the central poles of metropolitan systems have lost their functional and symbolic relevance. More specifically, the Bologna Area is undergoing two tendencies: the first one is a process of residential decentralization from the capital town, capable of involving a plurality of social groups, which caused an enrichment of the social composition of "suburban" population. The second process is a partial substitution of the population in the city centre with new groups: this not only occurred with directional groups, but it has also interested new parts of the “service worker” class and members of metropolitan underclass, causing, consequentially, a growing complexity in central areas of the metropolitan system. The need to increase knowledge of Bologna territory has become more and more relevant, since the 70’s, when a series of important environmental transformations favoured a research interest that did not exclusively stopped within the city centre boarders, but rather encouraged the exploration of Bologna outer/suburban areas. Finally, in the urban/suburban discourse, this piece of research has highlighted how the search for a better quality of life (financial reasons, larger spaces, possibility to buy/rent for a better price, environmental issues) determines the choice to leave the centre of the city in favour of outer areas. The tendency that this doctorial work has brought to surface is the need to match a more manageable standard of living to the proximity to the city, despite the fact that this results in the stress caused to commuting and the lack of those cultural and entertaining facilities offered by the city. The new suburban inhabitants do not regret leaving the city, but, at the same time, do not feel emotionally attached to the new location at a community level: what they seem to look for is a more comfortable environment where to live in.

La città di Bologna e la sua storia: diffusione e condivisione delle conoscenze attraverso Webgis open source e Web Mapping

To understand a city and its urban structure it is necessary to study its history. This is feasible through GIS (Geographical Information Systems) and its by-products on the web. Starting from a cartographic view they allow an initial understanding of, and a comparison between, present and past data together with an easy and intuitive access to database information. The research done led to the creation of a GIS for the city of Bologna. It is based on varied data such as historical map, vector and alphanumeric historical data, etc.. After providing information about GIS we thought of spreading and sharing the collected data on the Web after studying two solutions available on the market: Web Mapping and WebGIS. In this study we discuss the stages, beginning with the development of Historical GIS of Bologna, which led to the making of a WebGIS Open Source (MapServer and Chameleon) and the Web Mapping services (Google Earth, Google Maps and OpenLayers).
