A Hybrid Algorithm for the Unbounded Knapsack Problem

Vincent Poirriez, Nicola Yanev, Rumen Andonov

This paper presents a new approach for exactly solving the Unbounded Knapsack Problem (UKP) and proposes a new bound that was proved to dominate the previous bounds on a special class of UKP instances. Integrating bounds within the framework of sparse dynamic programming led to the creation of an...

A third order sliding mode controller for a stepper motor

Michael Defoort, Frédéric Nollet, Thierry Floquet, Wilfrid Perruquetti

This paper deals with the robust control problem of a stepper motor subject to parameter uncertainties and load torque perturbation. The developed algorithm is based on third-order sliding-mode control such that a desired angular motor position is accurately tracked. The proposed scheme requires...

Integrating human factors in the design of intelligent systems: an example in air traffic control

Serge Debernard, Benoît Guiost, Thierry Poulain, Igor Crevits, David Annebicque, Patrick Millot

In the current organisation of air traffic control, some cooperative activities appear in the work of air traffic controllers, especially between Tactical Controllers (TC) and Planning Controllers (PC), who manage aircraft inside a sector to prevent collisions. These cooperative activities allow...

HCI-enriched approach for DSS development : the UP/U approach

Hela Ltifi, Mounir Ben Ayed, Christophe Kolski, Adel M. Alimi

In this paper we propose an approach aiming to integrate Human-Computer Interaction (HCI) aspects in decision support system (DSS) development. We propose an approach combining two methods: one issued from software engineering field (the Rational Unified Process) and the other one from the HCI...

New Human-Computer Interactions Using Tangible Objects: Application on a Digital Tabletop with RFID Technology

Sébastien Kubicki, Sophie Lepreux, Yoann Lebrun, Philippe dos Santos, Christophe Kolski, Jean Caelen

This paper presents a new kind of interaction between users and a tabletop. The table described is interactive and associated with tangible and traceable objects using RFID technology. As a consequence, some Human-Computer Interactions become possible implying these tangible objects. The multi-...

Adjustment of the Subject-and-Wheelchair Fore-and-Aft Stability

Philippe Vaslin, Arnaud Faupin, François-Xavier Lepoutre

A 2-D model has been designed for solving the problem of the subjectand-wheelchair fore-and-aft stability, and implemented into a simulation program, which computes the seat height and fore-and-aft position from the wheelchair dimensions, the subject's anthropometry, his sitting posture in the...

Performance-Based Reactive Navigation for Nonholonomic Mobile Robots

Michael Defoort, Jorge Palos, Annemarie Kökösy, Thierry Floquet, Wilfrid Perruquetti

This paper presents an architecture for the navigation of an autonomous mobile robot evolving in environments with obstacles. Instead of addressing motion planning and control in different contexts, these issues are described in connected modules with performance requirement considerations. The...

A novel higher order sliding mode control scheme

Michael Defoort, Thierry Floquet, Annemarie Kökösy, Wilfrid Perruquetti

A higher order sliding mode control algorithm is proposed for a class of uncertain multi-input multi-output nonlinear systems. This problem can be viewed as the finite time stabilization of a higher order input-output dynamic system with bounded uncertainties. The developed control scheme is based...

User modelling: the consideration of the experience of time during journeys in public transportation

Arnaud Brossard, Mourad Abed, Christophe Kolski, Guillaume Uster

With the generalization of mobile computing devices, everyone can access to a large amount of information anytime and anywhere; the difficulty for the user is to access to the relevant information. This is more accurate in the public transportation field where during their trip users want to reach...
