Real-Time Tools for Situational Awareness and Emergency Management in Transport Infrastructures
No full textCritical transport infrastructures such as interchanges, long tunnels and bridges represent the most vulnerable environments within a transportation network; they are characterized by limited access/egress points and high volumes of users in close confines. A number of factors must be addressed to ensure maximum safety of both travellers and emergency service personnel; these include emergency preparedness, timely support for the decision-making process, and planning of optimal interventions in emergency management situations. This paper discusses the integration of wireless sensor networks (WSNs) and virtual reality (VR) to support the self-evacuation of travellers and operational procedures of rescue personnel within these environments, focusing on two key aspects of emergency operations: (i) collecting real-time data and (ii) improving the timeliness of first responders through efficient provision of the collected data. Testimonials, technical results and recommendations collated from two pilot installations realised within the EU-funded SAVE ME project demonstrate the qualitative and quantitative impact of such an approach on emergency situation management
Exploitation of wireless sensor data in virtual reality for the provision of comprehensive support to tunnel safety training and emergency management
No full textTwenty years of tunnel incidents have produced more than 700 victims worldwide. In Europe alone, there have been more than 60 road accidents in tunnels. Major tunnels are not immune: Mont Blanc (March 1999), Tauern (May 1999), and Saint Gotthard (October 2001), produced 62 deaths and multiple injuries.
Despite structural and safety systems improvements, a number of factors must be addressed to ensure maximum safety. Factors include preparedness, timely support to the decision-making process, and planning optimal interventions in emergency management situations. This paper discusses the integration of wireless sensor networks (WSN) and virtual reality (VR) for through-life support to tunnel safety and emergency operations management.
A WSN system designed for roadside applications is employed for environmental and traffic monitoring, event detection, and indoor localization. Data from the WSN is passed to a VR application. The VR application provides a 1:1 scale 3D model of the locale; allowing the injection and visualisation of detected events, locations, and other relevant information to support training and emergency situations.
The modules presented were implemented and tested during the EU FP7 project SAVEME, which developed a system to detect incidents in transportation hubs and to support optimal evacuation guidance for multiple differently-abled travellers. For tunnel-specific challenges, SAVEME collaborated with the Gotthard Tunnel, CNVVF (Italian National Fire Brigade), and ANAS (Italian National Road Company). Testimonials and results obtained during training and live trials indicate how such a system can improve timeliness and provide responders with valuable additional capabilities in the event of an emergency

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
A REference implementation of interoperable indoor location & communication systems for First REsponders: The REFIRE project
No full text"Localization and navigation support in GPS-denied areas represents a challenge for humans and robots operating in emergency situations. Although a great deal of effort has been performed around this topics in the last decade, to date, there is not any off-the-shelf solution to provide location and data communication services for fire responders in deep indoor environments. Most of the solutions available are based on proprietary infrastructures deployed in the environment and able to provide accurate localization. These systems are not suitable for interoperating; hence, there is the need to develop standard communication and localization protocols. To overcome the above-mentioned limitations the REFIRE project proposes a system composed of deployable solutions exploiting low-cost, simple, highly standardized pre-installed landmarks. The REFIRE project has ambitious targets: to validate such solution in realistic scenarios and to anticipate the proliferation of unfitting proprietary location systems unable to interoperate.
