International audience This work presents the Adaptative Integrated Information System under Web (AIISW) for the management of hydrous resources. The AIISW is a natural extension of the IISW-WADI towards an adaptative and customised architecture according to the user profile or the context of use including : a research and indexation engine system, simulators, a GIS and meshing editors as well as graphic viewers. This AIISW allows on the one hand to manage in an automatic way data of simulators and on the other hand to exploit and calibrate eventually in real time the results of these simulations by corroborating them with extracted or identified parameters. Ce travail présente le Système d'Information Intégré Adaptatif sous Web (SIIAW) pour la gestion des ressources hydriques. Le SIIAW est une extension naturelle du S2IW-WADI vers une architechture adaptative et personnalisée en fonction de l'utilisateur et du contexte d'utilisation incluant: un système de recherche et d'indexation, des codes de simulations, un SIG et des mailleurs ainsi que des visualiseurs graphiques. Ce SIIAW permet ainsi d'une part de manipuler de manière automatique les données des simulateurs et d'autre part d'exploiter et de caler éventuellement en temps réel les résultats de ces simulations en les corroborant avec des paramètres extraits ou identifiés.

The Stranger

The principal aim of this study is to participate in the current renewed discourse on the meaning of friendship, initiated in 1994 by the French philosopher Jacques Derrida with his Politics of Friendship, by combining the philosophical method of inquiry with the hermeneutical approach to poetic representations of friendship in the Iliad, the Divine Comedy, and the Decameron. It examines friendship not only as the unique love between two persons based on familiarity and proximity, but as the love for the one who is far away, the stranger, for this is a natural extension of the implicit love of the distant other, of the other-as-stranger – what Emmanuel Levinas has called "the infinity of the Other" – which is concealed in our friend, and which, in the words of Maurice Blanchot, puts us "authentically in relation" with him or her.

Accuracy Problem

Abstract A Time-To-Rollover (TTR) metric is proposed as the basis to assess rollover threat for an articulated vehicle. Ideally, a TTR metric will accurately “count-down” toward rollover regardless of vehicle speed and steering patterns, so that the level of rollover threat is accurately indicated. To implement TTR in real-time, there are two conflicting requirements. On the one hand, a faster-than-real-time model is needed. On the other hand, the TTR predicted by this model needs to be accurate enough under all driving scenarios. An innovative approach is proposed in this paper to solve this dilemma and the whole process is illustrated in a design example. First, a simple yet reasonably accurate yaw/roll model is identified. A Neural Network (NN) is then developed to mitigate the accuracy problem of this simplified real-time model. The NN takes the TTR generated by the simplified model, vehicle roll angle and change of roll angle to generate an enhanced NN-TTR index. The NN was trained and verified under a variety of driving patterns. It was found that an accurate TTR is achievable across all the driving scenarios we tested.

Camera placement in a virtual environment consists of positioning and orienting a 3D virtual camera so as to respect a set of visual or cinematographic properties defined by the user. Carrying out this task is difficult in practice. Indeed, the user has a clear vision of the result he wants to obtain in terms of the arrangement of the objects in the image. In this chapter, the authors identify three areas of research that are relatively little covered by the literature dedicated to camera placement and which nevertheless appear essential. On the one hand, existing approaches offer little flexibility in both solving and describing a problem in terms of visual properties, especially when it has no solution. They propose a flexible solution method which computes the set of solutions, maximizing the satisfaction of the properties of the problem, whether it is over constrained or not. On the other hand, the existing methods calculate only one solution, even when the problem has several classes of equivalent solutions in terms of satisfaction of properties. They introduce the method of semantic volumes which computes the set of classes of semantically equivalent solutions and proposes a representative of each of them to the user. Finally, the problem of occlusion, although essential in the transmission of information, is little addressed by the community. Consequently, they present a new method of taking into account occlusion in dynamic real-time environments.

Ethernet is the most promising solution to reduce complexity and enhance the band- width in the next generation in-car networks. Dedicated Ethernet protocols enable the real-time aspects in such networks. One promising candidate is the IEEE 802.1Q Time- Sensitive Networking protocol suite. Common Ethernet technologies, however, increases the vulnerability of the car infrastructure as they widen the attack surface for many com- ponents. In this paper proposes an IEEE 802.1Qci based algorithm that on the one hand, protects against DoS attacks by metering incoming Ethernet frames. On the other hand, it adapts to the behavior of the Credit Based Shaping algorithm, which was standardized for Audio/Video Bridging, the predecessor of Time-Sensitive Networking. A simulation of this proposed Credit Based Metering algorithm evaluates the concept.

Automata, Logic and Semantics International audience The paper presents a condition necessarily satisfied by (tiling system) recognizable two-dimensional languages. The new recognizability condition is compared with all the other ones known in the literature (namely three conditions), once they are put in a uniform setting: they are stated as bounds on the growth of some complexity functions defined for two-dimensional languages. The gaps between such functions are analyzed and examples are shown that asymptotically separate them. Finally the new recognizability condition results to be the strongest one, while the remaining ones are its particular cases. The problem of deciding whether a two-dimensional language is recognizable is here related to the one of estimating the minimal size of finite automata recognizing a sequence of (one-dimensional) string languages.

By mobilizing the theoretical framework of the specificity of SMEs, this work tries, through the observation of accounting practices, to answer the question of the relevance (production and use) of the accounting data for the managers of Moroccan SMEs. Indeed, through semi-structured individual interviews with SME managers, accounting and financial directors of SMEs and accountants, it is about to describe the different accounting practices of SMEs on the one hand, and to highlight potential determinants that may explain the differentiation of these practices on the other hand.

In contrast to many investigations of cellular automata with regard to their ability to accept inputs under certain time constraints, in this paper we are studying cellular automata with regard to their ability to generate strings in real time. Structural properties such as speedup results and closure properties are investigated. On the one hand, constructions for the closure under intersection, reversal and length-preserving homomorphism are presented, whereas on the other hand the nonclosure under union, complementation and arbitrary homomorphism are obtained. Finally, decidability questions such as emptiness, finiteness, equivalence, inclusion, regularity and context-freeness are addressed.

RESUMEN:Las salinas conforman territorios de características singulares y paisajes de especial encanto. Su estudio implica efectuar una doble aproximación: desde un punto de vista objetivo, que considera los elementos y fenómenos que tienen lugar en un determinado ámbito geográfico; y también subjetivo, que valora las cualidades que percibe o experimenta ante él un observador. Nuestro objetivo es recuperar la memoria de los territorios y los paisajes sobre la base de esta doble perspectiva, y elaborar series cartográficas que sirvan de base a sistemas de información geográfica patrimonial. Para ello resulta esencial combinar una exhaustiva búsqueda en archivo con un intenso trabajo de campo. El resultado permite conocer la existencia pretérita de elementos naturales y construidos, así como de usos y costumbres perdidos que durante una época existieron sobre un territorio concreto y conformaron unos paisajes singulares. Entre el material de archivo, las imágenes, los mapas y los planos realizados antes y después del desarrollo de la cartografía científica resultan de particular interés como fuentes de datos, aunque su interpretación requiere contar con conocimientos especializados. Asimismo, las manifestaciones artísticas tienen gran valor para conocer cómo se han experimentado unos paisajes que son el resultado de las culturas sucesivas que los conformaron. El artículo se centra en esta parte esencial de la metodología.ABSTRACT:Salt flats use to shape territories characterized by particular features, and particularly charming landscapes. Their study implies a double approach. On the one hand, an objective point of view considers every element and phenomenon that take place on a given area. On the other hand, a subjective perspective allows to assess all the spatial qualities that are perceived or experienced by the observer. Our main target aims to recover the historical memory of territories and landscapes, on the grounds of such a dual perspective. But also, to produce the corresponding cartographic series that will provide the digital basis for a geographic information system focused on the cultural heritage. For this purpose, it becomes essential to develop an exhaustive archival search, as well as an intensive fieldwork. They will permit to get a deep knowledge of every natural or built element in the area, together with the old uses and habits that shaped the current territories and landscapes. Among the historic sources, old pictures, and ancient or scientific maps should be stressed, due to their interest as essential sources of geographic data. However, they must be carefully read, what requires a specialised knowledge. Similarly, the artistic expressions are of great interest because of their ability to show the experience of a landscape as a result of an overlapping of cultures. The article focuses in such aspects of a global methodology.
