From the Rhin-Rhône TGV to Rhin-Rhône "territory" : reticularity, mobility and territoriality in an intermediary space
2013
High-speed rail, destined to reduce the times-distances between major French and European cities, tends to push intermediary spaces into a rather unfavorable situation. Strongly polarized by the large urban centers that surround them, these intermediary areas are usually reduced to their sole status of transit areas. However, the Eastern tract, the first section of the LGV Rhine-Rhône project, through its regional dimension, constitutes a factor in the emergence of a territorialization process of the Rhine-Rhone area. Thus, the arrival of high speed rail is responsible for the creation of a network of cities that extends from Dijon to Basel. To address this territorial issue, a detailed ana…
Du TGV Rhin-Rhône au "Territoire" Rhin-Rhône : réticularité, mobilité et territorialité dans un espace intermédiaire

Scalable Deployment of Efficient Transportation Optimization for SMEs and Public Sector
2014
Transportation planning is central activity in logistic network design. In this study, we examine the deployment of optimization methodology to transportation planning. More specifically, we examine the adoption of system solving the well-known combinatorial optimization problem, the vehicle routing problem (VRP). Its application has resulted in efficiency gains in transportation logistics, but they have not been very widespread, and especially small-scale operators have not yet benefited from these systems. In this paper, we present a prospective case study on the issues during deployment of optimization, especially in the context of small and medium enterprises (SMEs). We propose a novel …
On solving separable block tridiagonal linear systems using a GPU implementation of radix-4 PSCR method
2018
Partial solution variant of the cyclic reduction (PSCR) method is a direct solver that can be applied to certain types of separable block tridiagonal linear systems. Such linear systems arise, e.g., from the Poisson and the Helmholtz equations discretized with bilinear finite-elements. Furthermore, the separability of the linear system entails that the discretization domain has to be rectangular and the discretization mesh orthogonal. A generalized graphics processing unit (GPU) implementation of the PSCR method is presented. The numerical results indicate up to 24-fold speedups when compared to an equivalent CPU implementation that utilizes a single CPU core. Attained floating point perfor…
Los caminos de la gobernanza, Expo Zaragoza 2008 España
2005
Am 16. Dezember 2004 wählte das Bureau international des expositions (B.I.E.) Spanien und seine Kandidatenstadt, die Metropole Saragossa, als Organisationsland für die nächste internationale Ausstellung „International Exhibition of Zaragoza Spain 2008: Water and Sustainable Development“. Wir analysieren zunächst die Entwicklung "der Wege" der Kandidaturen zur Wahl der Gastgeberstadt der Internationalen Ausstellung 2008, dann greifen wir in einem zweiten Mal den gesamten Vorgang der Ausarbeitung, Begründung und Durchführung der Internationalen Ausstellung 2008 in Saragossa auf im Kontext der Globalisierung neue städtische Formen und Formen des Regierens hervorbringen, indem alle finanziellen…

IoT-MAAC: Multiple Attribute Access Control for IoT environments
2020
Access Control is an important security service that should be considered in IoT environments in order to offer reliable IoT services. Access control in IoT environments concerns not only the access of IoT users to IoT services and objects, but also the access of IoT objects to IoT gateways. In this paper, we specify an access control mechanism that considers the access of IoT objects to IoT gateways in order to enhance the reliability of IoT data provided by the IoT objects. Our proposed access control mechanism, called IoT-MAAC (Multi Attribute Access Control), allows retrieving requested data from the most reliable and secured IoT objects among the available objects in the IoT environmen…
An Augmented Campus Design for Context-aware Service Provision
2005
This paper deals with the design of a multi-modal system for pervasive context-aware service provision and human-environment interaction in augmented environments by the use of Personal Digital Assistants (PDA) or SmartPhones. The system enables mobile devices and remote displays to perform as interaction devices with pervasive applications which run on a dynamically composed server network. Visual interaction for service setup and provision are driven by appropriate graphical interfaces and XML-based protocols, which are dynamically composed according to the type of service and to the user current position by means of a mobile agent-based framework. The paper discusses both protocols, hard…
How relevant are local climate zones and urban climate zones for urban climate research? Dijon (France) as a case study.
2018
17 pages; International audience; Several typologies of urban surface properties have been proposed, in recent years, for urban heat island studies and climate modeling. Some were specifically developed for cities and urban climate issues, like the Urban Climate Zones, and the more recent Local Climate Zones. The initial objective of this paper is to evaluate the capacity of these two typologies to identify thermal environments in and around cities, and to determine which typology best captures the daily spatio-temporal patterns of surface and urban canopy heat islands. To simulate urban climate with a model, LULC data based on a given typology are required. To avoid circularity, we combine…
Training pre-service and in-service secondary school teachers: Analysis of changes in perceptions about quantum physics concepts and NoS views
2016
In this work we focus on the study of the changes in perceptions about Quantum Physics concepts and Nature of Science (NoS) Views of secondary school teachers attending three different typologies of professional development courses on Modern Physics . An open-ended questionnaire has been properly developed and administered in order to investigate Quantum Mechanics conceptual issues, NoS views and motivational aspects for all involved teachers. The same questionnaire has been submitted to the teachers both prior-to and after the courses. The analysis of teachers’ pre-instruction answers highlights that the majority of them show several difficulties on both conceptual knowledge and epistemolo…
