M. T. Ciceró. Discursos XVI. Sobre el govern de les províncies consulars. Discurs en defensa de Luci Corneli Balb
No full textEl 5 d’agost del 57 aC, Marc Tul·li Ciceró desembarcava a Brundísium i posava fi al seu exili després d’aconseguir el tan esperat perdó. Els dos discursos que presentem en aquest volum formen part del conjunt d’actuacions forenses que l’orador va protagonitzar durant el període immediatament posterior a aquest fet. Són textos, per això, amb un marcat rerefons polític, determinats en gran mesura per les tenses i oscil·lants relacions de Ciceró amb els membres del triumvirat, principalment amb Cèsar i amb Pompeu.
En el primer discurs, Sobre el govern de les províncies consulars, Ciceró defensarà la continuïtat dels comandaments provincials de Cèsar, de qui farà un encès elogi; en el segon, el discurs En defensa de Luci Corneli Balb, l’orador aconseguirà l’absolució d’aquest influent ciutadà originari de Gades, protegit tant de Cèsar com de Pompeu, a qui s’acusava d’haver usurpat la ciutadania romana
Development of digital twin models supporting ambient assisted living
No full textWorld population aging requires finding solutions to
improve independent living options. Ambient Assisted
Living (AAL) is making step forward developing services
supporting the elderly, but the implementation of
predictive environments is still far away.
Besides, the emerging Digital Twin (DT) concept has
begun to shape the first cognitive environments that
integrate users into assessments, improving efficiency,
prevention, and prediction of likely events through realtime
AI computing.
This paper aims to provide a prototype of a Cognitive
Building framework based on DT models that develop
high-level knowledge to achieve real-time Scenario
Awareness and offer appropriate AAL services once
anomalies are detected
"Urbanistica" delle acque interne: problemi generali e casi particolari (la Cispadana e Forum Corneli)
No full textLo studio ricostruisce la funzione dei corsi d'acqua naturali ed artificiali come fattori determinanti del'assetto urbanistico delle città romane. Come caso emblematico viene approfondito il centro abitato di Imola/Forum Corneli, di cui sono analizzate varie testionianze archeologiche, anche inedite, che evidenziano lo stretto rapporto funzionale sussistente tra la città e le acque periurbane ed urbane
Development of augmented BIM models for built environment management
No full textTraditional surveys in the built environment are time-consuming and usually result in enormous amounts of data, that are difficult to manage and contains bias. Therefore, BIM modeling of both geometries and related information leads to inconsistent, incomplete, or the other way around highly detailed models that need to be reworked afterwards, slowing the design process. The proposed methodology combines point cloud surveying technique, photogrammetry, and BIM within a game engine platform to define a workflow for an incremental model semantic enrichment that leads to an augmented BIM environment. The case study prototype allows stepwise accurate integration of detailed BIM objects by easing positioning them in the scene in accordance with the overlapped aligned images, giving the possibility of model enrichment only when it is required
Using argumentation to evaluate concept blends in combinatorial creativity
No full textThis paper motivates the use of computational argumentation for evaluating ‘concept blends’ and other forms of combinatorial creativity. We exemplify our approach in the domain of computer icon design, where icons are understood as creative artefacts generated through concept blending. We present a semiotic system for representing icons, showing how they can be described in terms of interpretations and how they are related by sign patterns. The interpretation of a sign pattern conveys an intended meaning for an icon. This intended meaning is subjective, and depends on the way concept blending for creating the icon is realised. We show how the intended meaning of icons can be discussed in an explicit and social argumentation process modeled as a dialogue game, and show examples of these following the style of Lakatos (1976). In this way, we are able to evaluate concept blends through an open-ended and dynamic discussion in which concept blends can be improved and the reasons behind a specific evaluation are made explicit. In the closing section, we explore argumentation and the potential roles that can play at different stages of the concept blending process
Digital Twin for a resilient management of the built environment
No full textResilient management of the built environment is a strategic objective, made even more evident by recent events, not only in terms of managing chronic stresses such as social, economic and financial stresses, but especially emergency situations. Human settlements can be considered complex systems and when disaster strikes, the degree of complexity is amplified exponentially. Thus, traditional management systems, based on classical paradigms, may be completely ineffective. Therefore, new management approaches are needed to implement safety, resilience and sustainability. In this context, this paper illustrates a research where Digital Twin (DT) is exploited as an adaptive system for the built environment, as a support to optimize post-disaster reconstruction processes with a focus on reactive security management, in order to implement resilience in a smart city perspective. Following this vision, the research project aims to realise a first extended framework enabling the implementation of digital twins in the built environment, then defining some DT demonstrators in the laboratory
Leveraging Extended Reality technologies with RFID to enhance on field maintenance of buildings
No full textThe combined use of BIM and the advanced visualization provided by Extended Reality technologies can improve productivity in the project management processes in construction. This paper concerns an application of MR for seamless data retrieval from a BIM platform towards field workers in charge of maintenance. For instance, in case a failure of any systems has been claimed, workers must retrieve the information about the localization of components prior to repairing. This step can be facilitated by on field data visualization through MR. As the number of on field repair actions is huge in complex buildings, minimizing the time required for the alignment of virtual models is beneficial. Hence, an approach for model alignment that is based on the use of RFID tags has been developed. The first advantage is that these embedded devices are suitable for reuse at any survey with no need for re-deployment. Secondly, this approach does not require that the virtual model is displayed during the alignment, which makes it suitable for large models
Development of a Twin Model for Real-time Detection of Fall Hazards
No full textThe Architecture, Engineering and Construction (AEC) industry is still one of the most hazardous industries in the world. Researchers impute this trend to many factors such as the separation between the phases of safety planning and project execution, implicit safety issues and, most of all, the dynamic and complex nature of construction projects. Several studies show that the AEC industry could greatly benefit of latest advances in Information and Communication Technologies (ICTs) to develop tools contributing to safety management.
A digital twin of the construction site, which is automatically instantiated and updated by real-time collected data, can run fast forward simulations in order to pro-actively support activities and forecast dangerous scenarios. In this paper, the twin model of the Digital Construction Capability Centre (DC3) at the Polytechnic University of Marche (UNIVPM) is developed and run as a mock-up, thanks to the adoption of a serious game engine. This mock-up is able to mirror all the relevant features of a job site during the execution of works from a safety-wide perspective. In such a scenario, virtual avatars randomly explore the construction site in order to detect accessible, unprotected and risky workspaces at height, while warning the safety inspector in case additional safety measures are needed
