CONVIS: A tool enabling uninterrupted operation during refurbishments of complex buildings
Full text linkClash Detection refers to the identification of geometrical overlaps within a Building Information Model (BIM). This paper seeks to extend the notion of overlapping to activities: Given a construction site within a building, we seek to find clashes between construction activities and occupant routines. Such a situation is often encountered in the context of refurbishments of complex buildings operating 24/7 (e.g. airports, train stations, hospitals, prisons). By finding the influence radii of adverse effects resulting from construction - i.e. dust, noise and vibrations, functions may be temporarily relocated in order to guarantee uninterrupted operation. Our tool CONVIS implements these simulation and scheduling aspects and seeks to provide a digital project plan for refurbishments in the said context
ORe – A simulation model for Organising Refurbishments
No full textThe problem of interferences due to the refurbishing activities of a complex building, carried out in parallel with the daily activities that characterize it, is not to be underestimated, especially when talking about a hospital structure. Consequently, the benefits that would be obtained by reducing the presence of construction activities result important in terms of safety and health of users, above all hospital patients. Setting the best solution of Gantt in the early stages of planning can be a winning strategy, as well as being able to recognize the safest and fastest path (e.g. predicting which is the fastest way to reach the rooms taken into consideration by the refurbishment). At the same time, being able to check which activities are most penalized by the presence of the construction site and to set which are essential for the survival of the activities that characterize the environment to be refurbished, e.g. the hospital ward, is a valid support tool for the healthcare staff. The proposed tool aims, on the one hand, to help designers by proposing the best possible Gantt solutions in relation to the management of daily activities that can not be suspended, and on the other hand, to support healthcare staff in the organization of these latter
Polysemantic Entity Extension of Project Models. A theoretical overview to power computable representations
No full textThis research domain fits in the systemic decomposition/classification of the building organism, specifically focusing on the topic of ‘design entity’ computation models. Entities discussed are those regarding architectural spaces, building components and design process procedures for an AECO project. The paper looks at the progress achieved by the academia and industry in the digital representations of CAAD entities, both tangible and intangible, by reviewing their limits and potentials starting from the second half of the last century on. In order to contribute to the enhancement of existing building modelling standards in this field, we discuss the potentialities offered by multi-inheritance formalism, overcoming the limits of traditional static object-oriented representation, like the IFC standard. Certain object-oriented programming languages allow for multiple inheritance, which consents an object or class to inherit characteristics from many ’parent’ classes or superclasses. It is not the same as single inheritance, in which a class or an entity can only inherit from one specific class or entity at a time. That is, a design entity can take on different meanings depending on the context and domain of the actor using it, or it could have multifunctional uses. Recent most advanced research proposed the ’polysemantic’ entity that could have multiple superclasses at the same time. By analysing in deep computable project models, we schematize a theoretical framework where a new knowledge-based system synergically work with the basic commercial models – IFC-based – by means of ontologies and graphic systems, to enable semantic reasoning. As a result we aim at providing some helps for designers, software developers and academicians to power the CAAD entity representations of the tools they use
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
Dispelling the Myths Behind First-author Citation Counts
Full text linkWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
Bridging Cultural Heritage Ontologies in VR Environment. A framework for querying and reasoning on the Temple of Venus and Rome restoration and documentation
Full text linkVR applied to Architectural and Archaeological Heritage has a long history: Digital models in this field are evolving from an aesthetic simulation of reality, or, rather, a representation of the visual perception, to a more complex model: an information aggregation core. The investigation presents a research panel oriented to enhance the digital survey products - point clouds, meshes, 3D models -to be used as an intelligent visual archive assigning structured knowledge contents to artefacts’ geometry. The implemented case regards the Temple of Venus and Rome. Research, in progress, has been developed by the following steps:
) Subdividing the artefact geometry into subregions;
2) Developing the consolidation ontology for a few restoration classes;
3) Assigning (manually) to each artefact subcomponent, namely a mesh sub-region, a “smart label” including a link to its consolidation ontology instance.
The aim is to combine the potential of VR visualization with ontology reasoning systems
