How to prevent cyber-attacks in inter-vehicle communication network?
2015
In this work, we aim to secure communication in a vehicular network by providing a proactive mechanism that can detect and predict with a high accuracy the future behavior of malicious attacker. In fact, the mechanisms proposed in the literature consider only detection mechanisms and do not prevent attacks that may arise in the network. Simulation results show that our mechanism has a high detection rate, low false positive rate while generating a low communication overhead.
A Crisis Management Serious Game for Responding Extreme Weather Event
2017
Managing crisis with limited resources through a serious game is deemed as one of the ways of training and can be regarded as an alternative to the table-top exercise. This paper presents the so-called “Operasjon Tyrsdal” serious game, inspired by a real case of extreme weather that hit the west coast of Norway. This reference case is used to add realism to the game. The game is designed for a single player, while the mechanics are framed in such way that the player should deal with limited resources, and elevated event pressure over time to manage. Beside applying an iterative Scrum method with seven Sprint cycles, we combined the development work with desk research and involvement of test…
Identifying critical incidents in naturalistic driving data: experiences from a promoting real life observation for gaining understanding of road use…
2013
The methodology of naturalistic driving observation aspires to observe the driver and his environment while driving in natural driving settings. It is of great importance in research on road safety as this method of observing road users eliminates the disadvantages of traditional methods like simulator studies or interviews. However, it produces vast such amounts of data and challenges data reduction and data analysis. Therefore automatic methods for filtering critical incidents based on thresholds for numerical data are often applied to select the data to be analysed. This study reports a small-scale field trial in Valencia, Spain, which was conducted within the promoting real life observa…
Security, QoS and self-management within an end-to-end Cloud Computing environment
2015
Today, Cloud Networking is one of the recent research areas within the Cloud Computing research communities. The main challenges of Cloud Networking concern Quality of Service (QoS) and security guarantee as well as its management in conformance with a corresponding Service Level Agreement (SLA). In this thesis, we propose a framework for resource allocation according to an end-to-end SLA established between a Cloud Service User (CSU) and several Cloud Service Providers (CSPs) within a Cloud Networking environment (Inter-Cloud Broker and Federation architectures). We focus on NaaS and IaaS Cloud services. Then, we propose the self-establishing of several kinds of SLAs and the self-managemen…
Who can go back to work when the COVID-19 pandemic remits?
2020
AbstractThis paper seeks to determine which workers affected by lockdown measures can return to work when a government decides to apply lockdown exit strategies. This system, which we call Sequential Selective Multidimensional Decision (SSMD), involves deciding sequentially, by geographical areas, sectors of activity, age groups and immunity, which workers can return to work at a given time according to the epidemiological criteria of the country as well as that of a group of reference countries, used as a benchmark, that have suffered a lower level of lockdown de-escalation strategies. We apply SSMD to Spain, based on affiliation to the Social Security system prior to the COVID-19 pandemic…
Human Trafficking: The Viscous Link Between Vulnerability and Proximity Violence
2020
The definition of “human trafficking”, adopted by the United Nations Protocol, clearly describes how the international community has outlined the concepts of victim and perpetrator. Despite the definitive effort made by this Protocol, the present chapter seeks to throw light on the fuzzy area existing within the rapport between vulnerability and proximity violence which makes the consensual exploitation of the victim by the trafficker possible as well as making it difficult to outline its contours in the courtrooms.
Silent say, saying effective and discourse mask
2021
In communication, every speaker must choose meticulously the aptness in the word, the gesture, the smile, the look or even the silence. The being-speaker hides and beyond protects himself behind his discursive mask which provides him with a linguistic security. While many disciplines - social psychology, psychoanalysis and philosophy – have seized the notion of the mask in their frame of reference, this concept still remains absent today in the language sciences. However, the game of masks substitution is fundamental in language activity. This game is so usual that we do not even notice it anymore, except in situations where we are explicitly asked to make an effort to adapt to the rule of …
The powers of masculinization in humanitarian storytelling: the case of the surgeon María Gómez Álvarez in the Varsovia Hospital (Toulouse, 1944–1950)
2020
This contribution is focused on analysing the power of 'masculinization' through which traditional humanitarian storytelling has been shaped. Strongly marked by a patriarchal vision, humanitarian accounts have traditionally hidden the work of women while stressing that performed by men, who appeared represented as true protagonists and, even, as heroes. In particular, this article analyses the professional career of a Spanish female surgeon named Maria Gomez (1914-1975) between 1944 and 1950, when she worked in a small charitable hospital based in Toulouse (France) for improving the health-care conditions of Spanish Republican refugees. Known as Hospital Varsovia or as Walter B. Cannon Memo…
The significance of soils and soil science towards realization of the United Nations Sustainable Development Goals
2016
Abstract. In this forum paper we discuss how soil scientists can help to reach the recently adopted UN Sustainable Development Goals (SDGs) in the most effective manner. Soil science, as a land-related discipline, has important links to several of the SDGs, which are demonstrated through the functions of soils and the ecosystem services that are linked to those functions (see graphical abstract in the Supplement). We explore and discuss how soil scientists can rise to the challenge both internally, in terms of our procedures and practices, and externally, in terms of our relations with colleague scientists in other disciplines, diverse groups of stakeholders and the policy arena. To meet th…
Adding the Mureş River Basin (Transylvania, Romania) to the List of Hotspots with High Contamination with Pharmaceuticals
2020
Background: The Mureș River Basin is a long-term heavily polluted watershed, in a situation of climate changes with increasing water flow and related decreasing dilution capacity. Here, a mixture of emerging pollutants such as pharmaceuticals were targeted to reveal potential risks regarding the natural lotic ecosystems. Due to the continuous discharge into the environment, pharmaceuticals are gaining persistent organic pollutant characteristics and are considered emerging pollutants. Based on the hazard quotient, this research highlights the dangerous concentrations of carbamazepine, ibuprofen, furosemide, and enalapril in river water. Results: High levels of four pharmaceutical compounds …
