L'individuazione dell'Unità Minima di Intervento: opportunità e problemi di metodo
No full textLa natura aggregata dei centri storici richiede che gli interventi (di miglioramento sismico, energetico, ecc.) non vengano progettati per ogni unità immobiliare, bensì tenendo conto di tutto l'edificio di cui esso partecipa. La necessità di individuare le Unità Minime che compongono gli aggregati deve superare, tuttavia, le numerose difficoltà operative legate alla conoscenza dell'episodio urbano

AOA estimation with EM lens-embedded massive arrays
Full text linkRecently, EM lens-embedded massive array antennas have been proposed for next 5G mobile wireless communications, as the adoption of a lens allows to discriminate the AOA of signals in the analog domain, with the possibility to preserve the processing complexity lower with respect to traditional massive arrays. In fact, in such a way, complex ADC chains can be avoided and the number of required antennas can be decreased. By exploiting these advantages, in this paper we study the possibility to use a single EM lens massive array at mm-wave for the AOA estimation of the received signal. In this perspective, ML estimator and practical approaches, tailored for the considered scenario, are derived. Results, obtained for different number of antennas, confirm the possibility to achieve interesting AOA estimation performance with an extremely compact architecture

Direct position estimation from wavefront curvature with single antenna array
Full text linkIn this paper we investigate the possibility to perform direct positioning by retrieving information from the wavefront curvature. Despite such an approach has been considered in the past at microwave and acoustic frequencies using extremely large antennas, it is of interest to investigate its potential exploitation at mm-wave with practical size antennas in the context of next 5G systems. Thus, here we first consider a dedicated model to gather the source position information from the wavefront curvature for different array architectures, i.e., traditional and lens-based arrays, and successively we derive the maximum likelihood estimator to investigate the attainable performance. Results, obtained for different number of antennas, i.e., for different array apertures, confirm the possibility to achieve interesting positioning performance using a single antenna array with limited dimensions
PROCEDURA PER IL RICONOSCIMENTO DELLE UNITA’ ELEMENTARI NEGLI AGGREGATI URBANI ATTRAVERSO LA COMPRENSIONE DEI PROCESSI TIPOLOGICI
No full textSeismic events in recent years have caused heavy damage to historic city centers. This calls for an
effective planning aimed at reaching an adequate decrease of the vulnerability of city centers
buildings. A deep knowledge of the structure of the urban environment ‐ and, to a lesser extent, of
the buildings the urban environment is made up of ‐ is the essential precondition for effectively
intervening on the urban fabric.
Currently, the most used means of knowledge are Vulnerability Assessment Forms, whose goal is
to assess not only the damage suffered by a building in the aftermath of an earthquake, but also
its habitability standards. These forms, which are supposed to assess the buildings as a whole, in
most cases only analyzes single buildings or cadastral units, since there is no well‐defined
procedure on how to identify single units within the urban fabric.
The identification of an Elementary Unit (i.e. the smallest independent unit within the fabric) is the
crucial point of this delicate process. This identification process, though, is based on weak and
misleading definitions, e.g. those that have been used up to today to fill in the Assessment Forms.
This work of research aims at clearly defining both the idea itself of Elementary Unit and a
procedure to identify it. This procedure could be extensively used not only in emergency
situations, but also for the regular preventive territory management.
This goal can be reached through a constant phenomenological examination of the urban fabric
buildings carried out using Muratori‐inspired typological analysis tools. By studying the
transformation process of the basic building types, it is possible to identify the Elementary Units
the urban fabric is made up of. Once the urban fabric structure has been comprehended, this work
will present a clear and most valid definition of Elementary Unit, which will simplify any later
examination of the urban fabric – from the identification of “subjects” for AeDES Forms, to the
drafting of Reconstruction Plans.
The case study of Ferrara offers a chance to verify the validity of the process of identification of
buildings within the urban fabric, designed on a real example. This will, in turn, prove the validity
of the term “Elementary Unit” and its strong connection with the concept of building type and the
typological development

Strategia territoriale, intervento locale: considerazioni per la tutela e riqualificazione delle aree fluviali. / Territorial strategy, local action: observations for the protection and improvement of the river areas.
No full textSvolgere un’attività progettuale applicata a contesti di valore ambientale rilevante – come quelli rappresentati dalle aree fluviali - significa, in generale, posizionarsi operativamente in una condizione necessariamente ricettiva di esigenze che vedono la trasformazione territoriale come atto di sintesi tra scelte tecniche e decisioni programmatorie - anche politiche - d’intervento.
La disciplina della progettazione ambientale - propria della cultura tecnologica sua generatrice - utilizza il codificato di processo, in questo caso, sia per la tutela di questi specifici scenari ambientali di pregio (perduto) da riqualificare, sia come elemento regolatore, o di controllo, dei vantaggi economico-sociali prodotti dall’azione pianificatoria alle diverse scale. / The progress of a design process in contests of environmental value, such as river areas, means operatively to receive instances about the territorial transformation.
That is, an act of synthesis between technical choices and intervention policy.
The discipline of environmental design uses its own coded process. In this case, it concerns the protection of these specific valuable environmental scenarios to be redeveloped and the regulation and control of social and economic benefits that are produced by the planning action at different scales
