Data-driven Interactive Multiobjective Optimization : Challenges and a Generic Multi-agent Architecture
2020
In many decision making problems, a decision maker needs computer support in finding a good compromise between multiple conflicting objectives that need to be optimized simultaneously. Interactive multiobjective optimization methods have a lot of potential for solving such problems. However, the growth of complexity in problem formulations and the abundance of data bring new challenges to be addressed by decision makers and method developers. On the other hand, advances in the field of artificial intelligence provide opportunities in this respect. We identify challenges and propose directions of addressing them in interactive multiobjective optimization methods with the help of multiple int…
A decomposition approach for multidimensional knapsacks with family-split penalties
2022
The optimization of Multidimensional Knapsacks with Family-Split Penalties has been introduced in the literature as a variant of the more classical Multidimensional Knapsack and Multi-Knapsack problems. This problem deals with a set of items partitioned in families, and when a single item is picked to maximize the utility, then all items in its family must be picked. Items from the same family can be assigned to different knapsacks, and in this situation split penalties are paid. This problem arises in real applications in various fields. This paper proposes a new exact and fast algorithm based on a specific Combinatorial Benders Cuts scheme. An extensive experimental campaign computational…
More Relevant Today Than Ever: Past, Present and Future of Media Performance Research
2020
Media performance is constitutive for functioning democracies. But what is the situation regarding media performance in the age of digitalisation? And how can media performance continue to be assured under the current difficult economic conditions for the news industry? In this essay, we give a short overview of how media performance research has developed from the introduction of private broadcasting to the spread of the Internet and social media. In the course of this development, the initial focus of media performance research on media content has broadened to include media quality from the user perspective. We show how the contributions to this thematic issue relate with existing lines …
Villes, densité et fractalité
1995
International audience; Ce bref article résumé les résultats d'analyses fractales effectuées sur les villes françaises à plusieurs dates pour deux niveaux d'observation: les tissus urbains caractérisés par la distribution spatiale des surfaces bâties d'une part, et le semis des villes de différentes tailles dans l'ensemble du territoire français d'autre part. Les méthodes de mesure sont rapidement expliquées, l'accent est mis sur la signification des nombres obtenus, leur comparaison d'une ville à l'autre et leur évolution au cours du temps.
Assessment of oral manifestations in pediatric patients with celiac disease in relation to marsh types
2022
To investigate the presence of molar-incisor hypoplasia and recurrent aphthous ulcers, the level of caries experience, and oral hygiene status, and to measure salivary flow rate, salivary buffer capacity, and salivary cariogenic microflora with Marsh types. A single-blind, prospective clinical study with 62 pediatric patients diagnosed with celiac disease with 64 controls. Clinical identification of molar-incisor hypomineralization (MIH) was followed according to the European Academy of Pediatric Dentistry criteria. DMFS and dfs index were used for the caries experience of each child. The clinical diagnosis of RAU was present or not. Oral hygiene was surveyed by recording the OHI-S and the …
Enseñanza de las ciencias : revista de investigación y experiencias didácticas
2021
Este trabajo pretende identificar los problemas más relevantes para la educación obligatoria en el campo de la alimentación y la actividad física desde el punto de vista de la educación para la salud. Para ello, se realizó una revisión bibliográfica y una consulta a expertos a través de un estudio Delphi y de un encuentro presencial. Esta combinación ha permitido consensuar entre diferentes sectores profesionales no solamente una lista de problemas y contenidos competenciales necesarios sino también aquéllos considerados como prescindibles. Los resultados de este estudio permitirán actualizar la educación alimentaria en la escuela y replantearse el curriculum desde una perspectiva que integ…
Temporal Denoising of Kinect Depth Data
2012
The release of the Microsoft Kinect has attracted the attention of researchers in a variety of computer science domains. Even though this device is still relatively new, its recent applications have shown some promising results in terms of replacing current conventional methods like the stereo-camera for robotics navigation, multi-camera system for motion detection and laser scanner for 3D reconstruction. While most work around the Kinect is on how to take full advantage of its capabilities, so far only a few studies have been carried out on the limitations of this device and fewer that provide solutions to enhance the precision of its measurements. In this paper, we review and analyse curr…

Design perspectives on technology, language teaching and language teacher education
2012
Despite the national strategies and major efforts to promote pedagogical use of ICTs in education, training programs for in-service teachers have often failed to develop sustainable pedagogical practice. For sustainable development, teachers need to be offered opportunities to explore the role of technology in relation to their concept of language and learning, and reforms should be designed in negotiation with teachers and students. In teacher education, aspiring teachers are being informed of the latest research results, but bringing the theory down to practice is a major task that calls for development work soundly based on research. In this paper we suggest that design-based research (D…
