Network Localization by Shadow Edges

Localization is a fundamental task for sensor networks. Traditional network construction approaches allow to obtain localized networks requiring the nodes to be at least tri-connected (in 2D), i.e., the communication graph needs to be globally rigid. In this paper we exploit, besides the information on the neighbors sensed by each robot/sensor, also the information about the lack of communication among nodes. The result is a framework where the nodes are required to be bi-connected and the communication graph has to be rigid. This is possible considering a novel typology of link, namely Shadow Edges, that account for the lack of communication among nodes and allow to reduce the uncertainty associated to the position of the nodes.Comment: preprint submitted to 2013 European Control Conference, July 17-19 2013, Zurich, Switzerlan

Strategies to improve Critical Infrastructures Robustness against the IEMI threat : a Review of relevant Standards and Guidelines on the topic

This paper aims to provide a brief overview of relevant standards, procedures and guidelines to standard bodies to manage the impact of the Intentional ElectroMagnetic Interference (IEMI) threat. It also provides guidelines for CI operators on how to reduce their exposure on IEMI hazards

Qualità dello spazio e diritto alla salute. Una ricerca interdisciplinare nei presidi ospedalieri

This paper presents the results and the approach of an interdisciplinary research that deals with the study of the relationship between the protection of the right to health and the design and use of space of hospitals. The research aims to provide criteria for the evaluation and design of space and organization in relation to regional and national policies on health. The approach takes as a reference the theory of social rights as rights based on the "relationship", whose effectiveness contributes to the quality of the spaces in which these relations take place. Key to the reading of the approach is the patient’s flow of experience in the public spaces of the hospital. The tools of configurational analysis in architecture were intertwined with sociological methods and investigation methodologies on the constitutional protection of rights. The research results are a set of knowledge articulated in a model, process data sheets and indicators for the evaluation of the flows in hospital

Interdisciplinary approach to evaluate environmental users’ perceived restoration in hospital public spaces

Objective – The study aims to: 1) assess the relationship between the quality of hospital's public spaces expressed in terms of accessibility and visibility of art and greenery and users' restorative experiences; 2) highlight how physical environment may promote health and wellbeing of patients and staff/user. Background – The issue of public spaces in hospitals is very debated today: the direction taken by a few decades is to implement these spaces giving them a humanization feature to promote the well-being of patients and staff. Architectural trends have developed around the creation of halls, mostly glazed, with more volumes appearing, and large dimensions. The importance of restorative spaces as a mediator factor for health outcomes among the users is increasingly recognized. Research questions – 1) Which public spaces are perceived to be more restorative? 2) Does familiarity with a place affect the users’ perception of restoration in hospital public spaces? 3) To what extent does the perception of restoration vary across settings that support similar functions but present varying levels of art and greenery? 4) How does the combined use of Technical Environmental Analysis (TEA) and Observed Based Environmental Assessments (OBEA) measures support our understanding of perceived restoration across different public spaces in hospital settings? Methods – A cross-sectional investigation was performed in seven public spaces of the Santa Maria Nuova Hospital (IT) by adopting TEA and OBEA tools. Technical Environmental Analysis: • Visits on site to evaluate the quality of the space, to assess the presence of artworks and/or greenery and to describe the historicity of the space • Spatial analysis: Space Syntax evaluation parameters (Hillier, 2007) to evaluate the integration of the space (e.g., visibility, accessibility) and to quantify the presence of artworks and green view (% isovist area from key points), performed by Visibility Graph Analysis (VGA) and Isovist Analysis. Observed Based Environmental Assessments: • This type of assessments implies an evaluation of public spaces done by the users (n = 327) (i.e., outpatient, staff, relative, volunteer and social services). Their recruitment was done in place. • Adapted version of the Perceived Restoration Scale (PRS) (1-5 Likert scale). Results – Overall the results seem to suggest that the public spaces had relatively high restorative qualities. However, significant higher perceived restoration was also found for the Medicherie cloister, suggesting that some architectural and natural features affected the result. In order to gain a better understanding of what aspects of the physical environment of hospital public spaces might have had an impact on users’ perception of restoration TEA and OBEA, data were merged together and their interaction was discussed. Conclusion – New insights about the concept of restoration and its interaction with physical characteristics of hospital’s public spaces is put forward. Furthermore, the methodology proposed by linking TEA and OBEA data contributes to a more reliable understanding of the influence that existing buildings might have on users’ well-being.publishedVersio
