Architettura - ri-Costruzione - Geometria: un percorso conoscitivo applicato allo studio delle volte "planteriane" in Torino

Le volte planteriane, dal nome dall'architetto Plantery attivo a Torino dai primi del ‘700, sono composte da una volta principale in cui si innestano voltine secondarie, assiali e angolari rispetto alla pianta, che consentono di coprire ambienti unitari ottenendo effetti di leggerezza e ariosità anche con frecce ridotte. La loro diffusione, fino agli anni ‘80 del secolo, in spazi di rappresentanza come gli atri dei palazzi, e la ricchezza delle variazioni sul tema legittimano una ricerca, che si avvale del rilevamento e della modellazione digitale, sulle relazioni fra i modelli geometrici e l'architettura realizzata, mediate dall'uso dei materiali, dalle tecniche costruttive e dagli stilemi decorativi. Plantery's vaults, by the name of the architect working in Turin since first years of ‘700, are composed by a main vault intersected by some axial and angular secondary vaults. Plantery's vaults allow to roof over unitary spaces obtaining effects of lightness also by small rises. Their diffusion, up to the ‘80s of the century, in boardrooms as palaces halls, and the richness of variations on the theme, justifies a research, that makes use of survey and digital modeling. This research is focused on the relationships between geometric models and built architecture, connected by use of materials, construction techniques and decorative styles

Parametric Thinking: Recognizing the "Architectural Formulas" in Cultural Built Heritage by Parametric Digital Modelling

Parametric digital modeling is today one of the most interesting tools on the international architectural design scene. At the same time it is one of the areas on which architectural criticism debates for some time. The use of parametric methods throughout the whole design process is favored by the rapid evolution of hardware and software devices and the everincreasing programming capabilities. However, the so-called Parametric Architecture has revealed its existence even before the digital revolution. Parametric Architecture is a definition coined by Luigi Moretti in the '40s. Furthermore, several scholars have found examples of parametric thinking from the origin of the history of Western architecture. The idea of verifying the existence of a "parametric thinking" in the Cultural Built Heritage, recognizing the parameters that could have guided the architectural composition and re-creating their relationships using tools of parametric digital modelling is the focus of the present proposal. It follows, deepens and develops a research carried out on the atria's vaults of several Baroque palaces in Turin

Porta Palatina historic survey drawings: digital replicas and comparison with updated digital acquisition

The proposed research aims at a comparison of the main historical surveys conducted on the Porta Palatina by different authors, with the data of a current digital survey. Through a work of redrawing and superimposition of information deducted from historical drawings, the analysis will highlight the consistency, discrepancies and inconsistencies of these drawings compared to the current state of the artefact. Therefore, the instrumental survey, necessary for the subsequent stages of graphical analysis, was carried out using photogrammetric techniques and Metashape software. The drawings taken into consideration for this work are those by Sangallo (1494–1497 ca.), by Palladio (1566 ca.), by Promis (1869) and by D'Andrade (1883): they constitute a very interesting documentary heritage, although heterogeneous, in which qualitative drawings (Sangallo), scaled drawings (D'Andrade), measured drawings (in vicentine’s feet for Palladio, in meters for Promis) alternate

Design Drawing

At the beginning of the twentieth century, in the architectural field, we witness the break with the nineteenth century tradition produced by the season of historical avant-gardes, in contrast with the strict control exercised by the academies. The early stages of development of the Modern Movement, which start from it, encourage a further departure from the past and from tradition: architecture, abandoning all sorts of decoration, becomes a vehicle for progress and new social commitments, in a utopian and idealistic key. The Modern Movement, considered in its entire temporal development, is expressed in a very articulated way, to the point that we can speak of a sort of collection of movements, which produces a very wide and diversified architectural proposal, conveyed through a representation (sketches, drawings, etc.), which reflects the essence of protagonists, of their value systems, of the critical points on which they are questioned, of the materials used and of the formal appearance of the buildings

Compensating the Noise of a Communication Channel via Asymmetric Encoding of Quantum Information

An asymmetric preparation of the quantum states sent through a noisy channel can enable a new way to monitor and actively compensate the channel noise. The paradigm of such an asymmetric treatment of quantum information is the Bennett 1992 protocol, in which the ratio between conclusive and inconclusive counts is in direct connection with the channel noise. Using this protocol as a guiding example, we show how to correct the phase drift of a communication channel without using reference pulses, interruptions of the quantum transmission or public data exchanges.Comment: 5 pages, 3 figure

Chapter Applicazioni di Motion graphic per la valorizzazione del patrimonio museale del Museo di Arte Orientale di Torino (MAO)

The 43rd UID conference, held in Genova, takes up the theme of ‘Dialogues’ as practice and debate on many fundamental topics in our social life, especially in these complex and not yet resolved times. The city of Genova offers the opportunity to ponder on the value of comparison and on the possibilities for the community, naturally focused on the aspects that concern us, as professors, researchers, disseminators of knowledge, or on all the possibile meanings of the discipline of representation and its dialogue with ‘others’, which we have broadly catalogued in three macro areas: History, Semiotics, Science / Technology. Therefore, “dialogue” as a profitable exchange based on a common language, without which it is impossible to comprehend and understand one another; and the graphic sign that connotes the conference is the precise transcription of this concept: the title ‘translated’ into signs, derived from the visual alphabet designed for the visual identity of the UID since 2017. There are many topics which refer to three macro sessions: - Witnessing (signs and history) - Communicating (signs and semiotics) - Experimenting (signs and sciences) Thanks to the different points of view, an exceptional resource of our disciplinary area, we want to try to outline the prevailing theoretical-operational synergies, the collaborative lines of an instrumental nature, the recent updates of the repertoires of images that attest and nourish the relations among representation, history, semiotics, sciences

Multi-scale analysis of the European airspace using network community detection

We show that the European airspace can be represented as a multi-scale traffic network whose nodes are airports, sectors, or navigation points and links are defined and weighted according to the traffic of flights between the nodes. By using a unique database of the air traffic in the European airspace, we investigate the architecture of these networks with a special emphasis on their community structure. We propose that unsupervised network community detection algorithms can be used to monitor the current use of the airspaces and improve it by guiding the design of new ones. Specifically, we compare the performance of three community detection algorithms, also by using a null model which takes into account the spatial distance between nodes, and we discuss their ability to find communities that could be used to define new control units of the airspace.Comment: 22 pages, 14 figure

Digital 3D reconstruction for the multiscale investigation on the Drawing of the fortified wall of Turin

[EN] The birth in Roman times, the development in the Baroque season and the massive Napoleonic demolition of the fortified wall of Turin constitute the phases of an event still clearly readable in the current urban fabric of the historical city center: the extant elements, even if portions of a highly fragmented layout, are punctual statements of an articulated pattern of superpositions, reconnections … Starting from the full bibliographic, cartographic and archival documentation, this contribute aims to actualize the numerous study schemes, drawn up over decades, anchoring their course, sketched by traces and additions, to the digital cartography. The goal is to construct a matrix from which it is possible to extrapolate thematic analysis oriented to survey and digital reconstruction of special items: city gates, bulwarks … The 3D representations could be used as a medium of interpretation and communication of the transformation, sedimentation and structuring of the urban form.Vitali, M.
