Heat transfer and vortical structures around a rotating cylinder with a spanwise disk and low-velocity crossflow

Thien Duy Nguyen, Souad Harmand

In this paper, we study the flow field characteristics and heat transfer of a rotating cylinder with a spanwise disk attached and subjected to low-velocity crossflow with a disk-cylinder diameter ratio, Dd/Dc = 3.06. Reynolds Averaged Navier-Stokes (RANS) simulations using the k-â̂Š realizable…

A framework for mobile and context-aware applications applied to vehicular social networks

Dana Popovici, Mikael Desertot, Sylvain Lecomte, Thierry Delot

The notion of context has become very important in computer science, especially when users are highly mobile. In a short period of time the environment changes; communication networks can become available or unavailable, user communities can appear or disappear, etc. The work presented in this…

Robust stabilization of linear discrete-time systems with time-varying input delay

Antonio Gonzalez Sorribes

This paper presents a sufficient condition to stabilize linear discrete-time systems with time-varying input delay and model uncertainties. The key idea consists of applying Artstein's reduction method and the scaled bounded real lemma; the robust stabilization problem is cast as a set of…

Effects of a turbulent wall jet over a non-confined backward-facing step

Nicolas Lancial, François Beaubert, Souad Harmand, Thien Duy Nguyen, G. Rolland

Experimental and numerical analysis of a turbulent wall jet downstream of a non-confined backward-facing step are presented. An infrared camera was used to visualize a temperature map of the heated plate downstream the step. A hot wire was utilized to measure the instantaneous local velocity and…

Geometric modeling of thick and closed surfaces : application to pelvic organs

Thierry Bay

Although surgery is often used to treat disorders coming from physiological changes in the spatial configuration of the pelvic organs, the process is poorly reproductible and controllable from one patient to another. The work described below consists in developping a realistic geometric modeling,…

Cooperation models between humans and artificial self-organizing systems: Motivations, issues and perspectives

Gabriel Zambrano Rey, Marco Carvalho, Damien Trentesaux

In this paper we introduce and discuss some of the concepts, motivations and requirements for cooperative models between humans and artificial self-organizing systems. After a brief review of alternative cooperation methods, an implicit cooperation-based approach through parameterization and…

Wavelet transform and Huffman coding based electrocardiogram compression algorithm: Application to telecardiology

Sid Ahmed Chouakri, O Djaafri, Abdelmalik Taleb-Ahmed

We present in this work an algorithm for electrocardiogram (ECG) signal compression aimed to its transmission via telecommunication channel. Basically, the proposed ECG compression algorithm is articulated on the use of wavelet transform, leading to low/high frequency components separation, high…

Toward a Reverse Comic Strip Based Approach to Analyse Human Knowledge

Frédéric Vanderhaegen

This paper presents an original prospective approach to analyze human knowledge based on the reverse comic strip concept. The approach consists in building a comic strip related to the on-line facial and voice characteristics of human operators and in identifying their possible associated lack of…

A common Work Space for a mutual enrichment of Human-machine Cooperation and Team-Situation Awareness

Patrick Millot, Marie-Pierre Pacaux-Lemoine

Especially in life-critical systems decision-making entails cognitive functions such as monitoring, as well as fault prevention and recovery. People involved in the control and management of such systems play two kinds of roles: positive thanks to their unique involvement and capacity to deal with…

Toward a Cooperative Action-Driven Decision Model of an Airport Security Process

Igor Crevits, Frédéric Vanderhaegen, Michel Labour, Ludovic Marechal

This paper presents a prospective and conceptual approach based on an action-driven decision that can lead to build a future decision. Such a process is driven by an action facilitated by the human-machine cooperation principles. Decision-making and action-making are then proposed to develop a…
