Interest Lower Body Point's Detection For Markerless Gait Analysis

Ahmed Derbel, Aladine Chetouani, Sylvie Treuillet, Bruno Emile, Nabila Mansouriy, Yousra Ben Jemaa

Tracking articulated interest points for human motion analysis is a challenging task in computer vision. Most of existing works use artificial markers placed on the body to facilitate their location. Alternative markerless strategies present limitations caused by the use of some predictive models…

MS lesions segmentation in 3D MR images using FCM and SVM

Amina Merzoug, Nacéra Benamrane, Abdelmalik Taleb-Ahmed

This paper proposes an approach to automatically segment MS lesions in MR images using fuzzy c-means (FCM) and a support vector machines (SVM) based on the sequential minimal optimization (SMO) in learning step. A postprocessing based on morphological operations was applied to refine the obtained…

Experimental and high velocity impact studies on hybrid armor using metallic and 3D textile composites

François Boussu, Marie Lefebvre, Benjamin Provost, Daniel Coutellier, Daniel Vallée

Hybridization of protective solution to high speed fragment has been studied to highlight the efficiency of a backing lightweight material with an existing metallic armor plate. Different lightweight structure as composite material with different types of fibrous reinforcement and resin have been…

Dissonance Engineering for Risk Analysis: A Theoretical Framework

Frédéric Vanderhaegen

This chapter presents a new original approach to analyze risks based on the dissonance concept. A dissonance occurs when conflict between individual or collective knowledge occurs. A theoretical framework is then proposed to control dissonances. It is based on the DIssonance MAneGEment (DIMAGE)…

Dissonance Engineering: A New Challenge to Analyse Risky Knowledge When using a System

Frédéric Vanderhaegen

The use of information systems such as on-board automated systemsfor cars presents sometimes operational risks that were not taken into account withclassical risk analysis methods. This paper proposes a new challenge to assess risksby implementing an automated tool based on the dissonance…

Application of a novel structure with observer for force-feedback haptic system under variable time delay

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

This paper addresses the implementation of a novel structure with observer for force-feedback haptic system under variable time delay. Theoretical approach for stabilizing haptic interface in interaction with a virtual environment is proposed. The obtained experimental results confirm the…

Step-crossing control of two-wheeled transporter based on Takagi-Sugeno approach: Comparison between state and descriptor form

Benyamine Allouche, Laurent Vermeiren, Antoine Dequidt, Michel Dambrine

In this paper, a new control design for a two-wheeled self-balanced mobile robot (TWMR) is considered. The aim is to propose a strategy for a controlled and safe crossing step in order to extend the use of TWMR by disabled persons. The crossing step problem is formulated as a stabilisation problem…

Step-crossing feasibility of two-wheeled transporter: Analysis based on Takagi-Sugeno descriptor approach

Benyamine Allouche, Laurent Vermeiren, Antoine Dequidt, Michel Dambrine

Steps are frequent obstacles in the human environment. To cross a small step, the system should shift immediately its center of mass to its new equilibrium. This task is not easy to perform and does not depend only on the performance of the stabilizing controller, but it is also highly linked to…

Model-Driven design flow for distributed control in reconfigurable FPGA systems

Chiraz Trabelsi, Rabie Ben Atitallah, Samy Meftali, Jean-Luc Dekeyser

One of the most challenging and time-consuming design tasks for dynamically reconfigurable FPGA (Field Programmable Gate Array) systems is the design of runtimeadaptation control. This aspect covers various points such as runtime-monitoring, reconfiguration decision-making and reconfiguration…
