Urban sketching for reading the spaces of the historic city. L’Aquila and its squares
No full textIn the history of the city of L’Aquila, squares have always had a pivotal role in the foundation and transformation of its design. In fact, squares in L’Aquila have always been part and parcel of the city’s image, each one with its specific identity and meaning; meeting and gathering places in which the inhabitants recognize themselves and of which they have suffered the absence during these years of reconstruction following the earthquake of 2009, still underway today, that is finally allowing the population to reclaim the spaces of the historic centre.
The paper delves into the values of hand and life drawing, which still has great potential as a scientific process made up of technique, perception and critical restitution, in order to read and document the urban spaces of the city’s identity and to recognize their historical and architectural values
Procedure per la modellazione HBIM del patrimonio architettonico
No full textThe book is dedicated to the study and the deepening of issues related to the knowledge, documentation and representation of architectural heritage through the development, experimentation and validation of HBIM procedures for the creation of customizable parametric models able to respond to the peculiarities of historical buildings, which can therefore be configured as useful tools to testify the historical - architectural values of the assets. The present work highlights the differences between BIM and HBIM, critically underlying the problems and potential of this procedure, which should not be understood as an extension of the BIM approach to historical buildings but differs from the latter in that founded on a different theoretical and methodological approach. HBIM procedure, in fact, refers primarily to a process of knowledge that starts from the survey, critically analysed and subsequently semantized, and leads to its critical restitution through the HBIM modelling. The model is no longer only an instrument of interpretation and representation, but a critical instrument of analysis and knowledge. Therefore, in order to obtain a scientifically valid modelling, the importance to declare and evaluate the sources on which the interpretative process is based appears evident and renewed. This consideration is amplified by the transition from two-dimensional representation to three-dimensional virtualization, which requires a geometric-dimensional and informative synthesis extended to the entire continuum of the artefact, and by the often incomplete knowledge that characterizes historical building. The main objective of the research concerns the development of procedures for the creation of HBIM models starting from the cognitive and documentary phase, by defining standards for their construction and validation. The achievement of these aims was reached also through the experimentation with visual programming tools, which aided to overcome some of the HBIM limits relating to the parameterization of complex elements typical of historical architecture, the expansion of the BIM database, to allow the documentation of the heritage, and the evaluation and declaration of the geometric and informative reliabilities of the models. Lastly, the proposed procedures and standards are tested and valitated through the HBIM modelling of a chosen case study
From the project drawing to the survey model: the Enrico Fermi school in Celano 1932-1934
No full textThe Enrico Fermi school in Celano was built between '32 and '34 by the Civil Engineers of Avezzano on a site previously occupied by the prison, destroyed by the earthquake that hit Marsica in 1915.
The building, which constitutes the evolution of the second project, consists of a C-shaped structure composed of a central body overlooking the main road and two short lateral ones which contains the main entrances to the school. In 2007, after a rehabilitation project, the building complex underwent major transformations that altered both its intended use and plant. In fact, the school became a multifunctional building and an auditorium, built in the internal courtyard and joint to the rest of the building, was added.
The study starts from an in-depth analysis of historical documents to understand the features and differences of the two projects of '27 and '32. The updated survey allows the creation of a complex restitutive model of the current state of the school and, through the integration with the information deriving from the historical documents, of a reconstructive model of the project of '32 following the modifications made by the Superintendent Alberto Riccoboni.
The use complex 3D models favour the study and understanding of architectural, typological and spatial characteristics of the building. The aim is to comprehend the story of the building and how it has evolved over time according to the needs of the residents, by comparing the initial projects with the reconstructive and the restitutive models
Modelling and Visualization Issues in the Architectural Heritage BIM
No full textBuilding Information Modelling constituted an instrument of great
innovation for the Architecture, Engineering and Construction (AEC) sector,
involving the entire building process because of the possibility to manage a large
amount of data and information. The application of BIM to architectural heritage
AHBIM (Architectural Heritage Building Information Modelling) still presents
aspects that are being investigated, due to the complexity and specificity of
cultural heritage such as the craftsmanship of historical buildings (far from
standardization of the elements and constructive modern processes, typical of
BIM) and the complexity of the information that the BIM methodology must
manage for the documentation of architectural assets. It is proposed a reflection
on the BIM processes as a tool for a complex representation of the architectural
heritage, where the “all-encompassing” nature of BIM is applied to an existing
reality. Taking into account a specific methodological approach to built heritage,
the work aims to investigate the potential offered by 3-D modelling and digital
visualizations for the study of historical, architectural, cultural and material
values of historic buildings
Memoria e fotografia nell’era digitale: il caso dell’Aquila
No full textLa diffusione delle ICT e dei social media ha determinato un cambiamento sociale nel modo in cui le persone interagiscono e comunicano. Ci troviamo di fronte a una democratizzazione dell’informazione, che trasforma gli utenti da semplici fruitori passivi a produttori, editori e condivisori di contenuti.
I social network, in particolare, sono oggi visti come ambienti per archiviare fotografie, condividendole con altre persone con interessi comuni. Le interazioni e la costruzione di relazioni si basano ormai spesso sulla creazione di una memoria e una conoscenza condivise e accessibili, fondate su fotografie, più o meno personali.
Il contributo presenta una riflessione sul bisogno di memoria, e mantenimento della stessa, manifestato dagli abitanti della città dell’Aquila dopo il terremoto del 2009, che ha provocato lo svuotamento del centro storico della città, e la conseguente rottura tra l’identità dei luoghi e la dimensione immateriale, intesa come spazio di vita quotidiano
From vacuum to atmospheric pressure: A review of ambient ion soft landing
No full textThe capability to deposit intact highly pure ionic species makes ion soft landing an advantageous mass spectrometric method able to create molecular layers on solid surfaces. Recent advances in this technique gave the possibility to manipulate solvent-free ions in open-air conditions. The high ionic current produced by the new sources as well as the developments of accelerated systems dramatically increase the efficiency of the soft landing process, opening new opportunities for surface modification with self-organized polyatomic structures. This review reports the developments of the ambient ion soft landing, highlights its most recent applications and discusses future perspectives
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Variations on the Author
Full text link“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
Full text linkWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
