Abstract

Archival science is suffering a radical change, often written in English. For non English-speaking communities, this implies the need for a translation of the most relevant archival texts. However, this poses several challenges and difficulties: different disciplinary communities, different uses of terms by different English-speaking communities, and different understandings, associated to different national traditions. In this regard, this text suggests several examples, as well as potential risks derived from a bad or poor understanding. In the same way, it explores some of the answers proposed by archival researchers, particularly essays published by Eric Ketelaar. According to this background, and on the basis of the Quine’s theory of indeterminateness, this text suggests two approaches to the problem: a sound ethnographical study of socio-cultural environments associated to different archival terms and discourses, as well as a deep conceptual analysis of some of the most relevant concepts in modern archival science.

Abstract

The proposed work, depicts a novel algorithm able to provide multiple pedestrian detection, based on the use of classical sensors in modern automotive application and context information. The work takes advantage of the use of Joint Probabilities Data Association (JPDA) and context information to enhance the classic performance of the pedestrian detection algorithms. The combination of the different information sources with powerful tracking algorithms helps to overcome the difficulties of this processes, providing a trustable tool that improves performance of the single sensor detection algorithms. Context in a rich information source, able to improve the fusion process in all levels by the use of a priori knowledge of the application. In the present work multilevel fusion solution is provided for road safety application. Context is used in all the fusion levels, helping to improve the perception of the road environment and the relations among detections. By the fusion of all information sources, accurate and trustable detection is provided and complete situation assessment obtained, with estimation of the danger that involves any detection. This work was supported by the Spanish Government through the Cicyt projects (GRANT TRA2010-20225-C03-01) and (GRANT TRA 2011-29454-C03-02). CAM through SEGVAUTO-II ( S2009/DPI-1509).

This paper exposes the situation of media education in Luxembourg educational context beginning with the idea that media presence is still insufficient. The article includes an analysis of Education policy and media education proposals through training courses carried out especially by the National Programmes Council. Other proposals are likewise explained.

Abstract

International audience; This paper reviews existing security mechanisms for aeronautical data link communication: current support and availability of such features are described. With an Open Systems Interconnection (OSI) reference model-driven analysis, each solution is classified and analyzed according to the layer where security is deployed and a relevant taxonomy is proposed. Moreover, advantages, drawbacks, and possible threats of every security mechanisms previously introduced are discussed. According to this security infrastructure overview, a proposal for an efficient security architecture adapted to the aeronautical context is made for future studies. Satellite communication-based system specific problematic is taken into account with a constraint bandwidth and the need of reduced overhead for any additional mechanisms.
