An ontology-based metamodel for multiagent-based simulations
2014
Multiagent-based simulations enable us to validate dierent use-case scenarios in a lot of application domains. The idea is to develop a realistic virtual environment to test particular domain-specic procedures. This paper presents our general framework for interactive multiagent-based simulations in virtual environments. The major contribution of this paper is the integration of the notion of ontology as a core element to the design process of a behavioral simulation. The proposed metamodel describes the concepts of a multiagent simulation using situated agents moving in a semantically enriched 3D environment. The agents perceive the geometric and semantic data in the surrounding environmen…
Introduction
2014
Nowadays, software engineers face a wide range of particular application domains such as electronic commerce, enterprise resource planning, mobile computing, self-organisation, pervasive and adaptive computing, etc. The resulting heterogeneity and required functionalities call for complex systems and open architectures that may evolve dynamically over time so as to accommodate new components and meet new requirements. This is probably one of the main reasons why the agent metaphor and agent-based computing are gaining momentum in these areas.
Interactive roll stabilization comparative analysis for large yacht: gyroscope versus active fins
2020
The problem of the active stabilization of ship motions is particularly important in the case of pleasure boats or in any case of passenger ships, since the commercial value of the ship is directly related to the comfort of the load transported in this case “people”, considered as stresses induced on them by the vessel movements, with particular attention to roll, given the ship geometric characteristics. Naval architects developed trough the years different solutions to reduce the roll of the ship, and consequentially to increase the passengers comfort, and the development of this solutions followed the progress of technology. Active fins have been the most used, but now the gyroscope solu…
Modelling Mechanical Wave Propagation: Guidelines and experimentation of a teaching–learning sequence
2008
This paper reports the design process and the experimentation of a teaching-learning sequence about the concept of mechanical wave propagation and the role played by media where waves are propagating. The sequence focuses on the central issue of the relationships between observable phenomena, like macroscopic behaviours of waves, and their interpretation and/or explanation in terms of corpuscular characteristics of media. We describe the design process with respect to the general framework of the Educational Reconstruction Model and the pedagogical tools used. Results of a teaching/learning experiment, involving a sample of 75 high school students, are also reported. Data analysis is mainly…
The Effects of the Use of Serious Game in Eco-Driving Training
2016
International audience; Serious games present a promising approach to training and learning. The player is engaged in a virtual environment for a purpose beyond pure entertainment, all while having fun. In this paper, we investigate the effects of the use of serious game in eco-driving training. An approach has been developed in order to improve players’ practical skills in terms of eco-driving. This approach is based on the development of a driving simulation based on a serious game, integrating a multisensorial guidance system with metaphors including visual messages (information on fuel consumption, ideal speed area, gearbox management, etc.) and sounds (spatialized sounds, voice message…
User-Centered Design of a National Medical Registry for Tick-Borne Diseases
2018
Tick-borne diseases are increasing in a global perspective, with Lyme disease and tick-borne encephalitis as the most frequent. The Norwegian National Advisory Unit on Tick-borne Diseases is preparing the development of a national medical registry for clinical follow-up of patients with tick-borne diseases based on the best practice guidelines and for research purposes. This paper presents the methodological approach of a user-centered design process applied in the initial phase of the registry development. A user workshop identified user needs, requirements and proposed a service workflow for the registry operation. As the next step, a simulation of the proposed service workflow was perfor…
Co-designing a social media service for civic participation
2010
User participation in social media design processes has similarities with civic participation for example in urban planning. Internet enables new virtual environments that can be planned collaboratively and be used for civic participation. In the Monimos case study we developed a social media website for immigrants and multicultural associations in a participatory design process together with the users. In this paper we present the critical issues in co-designing a social media service that aims at civic participation. We also give suggestions for how to cope with the challenges in a multicultural participation process. We claim that constant meta-level discussion about the goals and partic…
Carlo Scarpa : a [curious] shaft of light, a golden standard, the hands and a face of a woman : reflections on the design process and layout of Palaz…
2020
This study describes the spatial organization of the entire Gallery Regional Palace of Abatellis as a place of complex mediation between the commitment of the Carlo Scarpa project, the sense of measure and harmony and the requests of the curator Giorgio Vigni. The book tries to understand the link between the place and the design process of Scarpa, discarding the chronology of the intervention itself with reflections concerning the design process of the exhibition, they reveal a possible code message. It is a targeted reconnaissance, whose narrative is also recomposed by thanks to some clues (found during the study of the correspondence and drawings, not always known and published), which s…
Accessing and selecting menu items by in-air touch
2019
Is it possible to realize a non-visual, purely tactile version of an icon-based menu? Driven by such question, a hierarchical tactile dock was designed for an array of ultrasound emitters. The icons were conceived as spatio-temporal variable-speed sequences of tactile stimulation points, that are passively perceived as trajectories drawn on the palm of the hand. The recognition rate on four icons largely improved prior performance results obtained by active haptic exploration. As a result, a four-icons set can be used as the first level of a hierarchy of symbols that can be navigated by touch and gesture. The design process, based on controlled recognition experiments and exploration of dis…
Simplified thermal analysis of naturally ventilated dwellings
1991
Abstract A simplified comprehensive methodology for thermal comfort prediction in a naturally crossventilated room is described. The methodology mainly consists of the following three steps: • - analysis of the dynamic thermal behaviour of the given room, by means of the admittance procedure; • - evaluation of the air flows rates and their velocities in the room, by means of a new simplified method; • - thermal comfort prediction by means of the Fanger's theory. The results obtained appear satisfactory and the simplified methodology makes itself a useful tool for the identification of appropriate choices at the early stages of the design process, regarding naturally ventilated buildings. Th…
