Influences of aircraft seat adaptations on wheelchair user perceptions when transferring into and out of the seat: A pilot study

Victoria Spartacus, Christophe Gillet, Sebastien Paganelli, Dany Gagnon, Philippe Pudlo

Aircraft seat accessibility for wheelchair users is very complicated. The distance between two seats is very small which creates accommodation deficiencies. Improving air travel experience, and more specifically egress and ingress of aircraft seat could be associated with development of some…

Finite Control Set Predictive Control and State Estimation of Partially Observable Switching Linear Systems: Application to a Multicellular Converter

Abir Smati, Wassila Chagra, Denis Berdjag, Michael Defoort, Moufida Ksouri

This article is about a feedback control and state observation of a class of hybrid systems with some unobservable subsystems. When the system reaches an unobservable configuration, the state observer performance decreases, impacting the overall control performance of the system. For that reason,…

High-level area-performance-energy estimation framework for FPGA-based accelerators, Un framework haut niveau pour l'estimation du temps d'exécution, des ressources matérielles et de la consommation d'énergie dans les accélérateurs à base de FPGA

Mariem Makni

In recent years, the complexity of system-on-chip (SoC) designs has been dramatically increased. As a result, the increased demands for high performance and minimal power/area costs for embedded streaming applications need to find new emerged architectures. The trend towards FPGA-based accelerators…, Les systèmes embarqués sur puce (SoC: Systems-on-Chip) sont devenus de plus en plus complexes grâce à l’évolution de la technologie des circuits intégrés. Les applications récentes nécessitent des systèmes à haute performances. Les FPGAs (Field Programmable Gate Arrays) peuvent répondre à ces…

A consideration of the variability on the characteristics of a bogie’s suspension elements, towards the optimisation of maintenance operations, Prise en compte de la variabilité des caractéristiques de suspension d'un bogie pour l'optimisation des opérations de maintenance

Andrés Malo-Estepa

The reduction of maintenance costs is a key stake for the competitivity of railway rolling stock manufacturers. The optimization of maintenance operations can be addressed by less, better-planned overhaul operations, through an increase of the life-cycle of some components. Among the most…, La réduction des coûts de maintenance est l’un des enjeux majeurs auquel doit faire face l’industrie ferroviaire pour rester concurrentielle. Parmi les organes de suspension nécessitant un entretien périodique fréquent, les éléments à base métal-caoutchouc jouent un rôle clé dans le fonctionnement…

LMI approach for robust stabilization of Takagi–Sugeno descriptor systems with input saturation

Quoc Viet Dang, Laurent Vermeiren, Antoine Dequidt, Michel Dambrine

The aim of this article is to present a systematic framework for the design of a robust controller for uncertain nonlinear systems represented in the Takagi–Sugeno descriptor form. The design takes explicitly into account state constraints and also the saturation of the control input. Based on…

Nonlinear Static Output Feedback Control for Human Heart Rate during Treadmill Exercise

Tran Anh-Tu Nguyen, Mohamed Yagoubi

This paper presents a new control method for the nonlinear human heart beat rate dynamics during treadmill exercise. The reference trajectory represents a desired heart rate profile suggested by the physician. The goal is to design the treadmill speed input for tracking control purposes. Using…

A Robust Descriptor Approach for Nonlinear Tracking Control of Serial Robots

Tran Anh-Tu Nguyen, van Anh Nguyen Thi, Antoine Dequidt, Laurent Vermeiren, Michel Dambrine

This paper presents a method for the control design of a two degrees of freedom (2-DoF) serial manipulator using descriptor Takagi-Sugeno modelling. The design goal is to achieve a guaranteed H∞ model reference tracking performance while significantly reducing the numerical complexity of the…

Etude du contrôle et du transfert de la motricité des perchistes experts pour la réalisation de l'impulsion dans les activités athlétiques, Motor control and transfer of expert movement during take-off in track and field’s event

Maud Bassement

De nombreuses études ont abordé le champ du contrôle moteur de 1' être humain en passant par l'analyse et la modélisation de mouvements simples (atteintes de cibles, coordinations bi-manuelles ... ). Les théories élaborées par cette voie doivent pouvoir être appliquées à un mouvement…, Many studies investigate motor control during simple movements (such as reaching for a target or bimanual coordination), but the theories of motor control need to be tested during sport movement. One of the most spectacular activities in world of sport is pole vaulting. One critical phase in this…

High performance short-block binary regular LDPC codes

Latifa Mostari, Abdelmalik Taleb-Ahmed

LDPC code shows a good performance with long-block codes. However, certain channels are constrained to use short-block codes due to latency. Therefore, concatenated LDPC codes with iterative decoding is a good choice to get a good performance. Concatenated binary LDPC codes were introduced as a…

Caractérisation multi-physique et multi-échelle d'une installation de conversion d'énergie : application à une unité de cogénération biomasse, Multi-physical and multi-scale characterization of an energy conversion installation : application to a biomass cogeneration unit

Fateh Mameri

La micro-cogénération désigne la production simultanée de deux énergies finales et utilisables à partir d’une seule source d’énergie primaire. Le cas le plus fréquent est la production de la chaleur et de l’électricité. En France, la micro-cogénération concerne les petites puissances (< 36 kWel…, Micro-cogeneration refers to the simultaneous production of two final and usable energies from a single primary energy source. The most common case is the production of heat and electricity. In France, micro-cogeneration concerns small powers (< 36 kWel). Its interest lies in higher efficiencies…
