Liquid–solid two-phase jet in a turbulent crossflow: Experiments and simulations

Charlène Octau, Talib Dbouk, Michel Watremez, Damien Méresse, Marc Lippert, Jesse Schiffler, Laurent Keirsbulck, Laurent Dubar

Compared to single-liquid and liquid–liquid jets in crossflow (JICF), liquid–solid two-phase JICF is rarely studied. An experimental setup has been developed to investigate a vertical jet of liquid–solid mixture in water turbulent crossflow at Re≈2.2·104 over 4 s period. Rigid micro particles were…

Control of an automated wheelchair

Michael Gray, Thierry-Marie Guerra, Sebastien Delprat, Sami Mohammad

Due to the world's aging population, the development of affordable and easy to use wheelchairs is becoming a priority. In this study, the control of an automated wheelchair is proposed. The model equations are derived from the Euler-Lagrange equations, then a descriptor model is formulated.…

A Distributed Observer-Based Cyber-Attack Identification Scheme in Cooperative Networked Systems under Switching Communication Topologies

Anass Taoufik, Michael Defoort, Krishna Busawon, Laurent Dala, Mohamed Djemai

This paper studies an approach for detecting cyber attacks against networked cooperative systems (NCS) that are assumed to be working in a cyber-physical environment. NCS are prone to anomalies both due to cyber and physical attacks and faults. Cyber-attacks being more hazardous given the…

Energetic valourisation of waste tyres by pyrolysis: catalyst effect on tyres derived oil and gases

Hiba Rejeb, Emna Berrich, Mohamed Hachemi Chahbani, Fethi Aloui

In this paper, an experimental investigation is carried out to study the zeolite catalyst ZSM5 effects on pyrolysis tyres derived oil TDO and gases. Two percentages of zeolite catalyst have been chosen, i.e., 10% and 20%. Experiments were carried out in a semi-batch reactor under inert atmosphere.…

A query-based framework to improve BIM multi-domain collaboration

Sattler Léa, Samir Lamouri, Robert Pellerin, Virginie Fortineau, Mohammed Larabi, Thomas Maigne

Although BIM has been widely adopted in the past decade, multi-domain collaboration through BIM is still a struggle, involving different barriers such as trade-specific semantic definitions, data-schemas heterogeneousness and low levels of digital cooperation in AEC. After a brief review of…

Evaluation and qualification of mobile application quality.

Rudy Bisiaux, Mikael Desertot, Sylvain Lecomte, Dorian Petit

Development of mobile applications has previously encountered, and still encounters, challenges related to the specificity of the mobile world. The usual rules of software engineering tend not to respond to certain mobile development issues. In this paper, we identify and address the challenges of…

Heuristics for the single machine weighted sum of completion times scheduling problem with periodic maintenance

Hanane Krim, Rachid Benmansour, David Duvivier, Daoud Aït-Kadi, Said Hanafi

This paper tackles the single machine scheduling problem with periodic preventive maintenance in order to minimize the weighted sum of completion times. This criterion is certainly less studied than the makespan but it remains nonetheless interesting on the theoretical and practical levels. Indeed…

Valuing free-form text data from maintenance logs through transfer learning with CamemBERT

Juan Pablo Usuga Cadavid, Bernard Grabot, Samir Lamouri, Robert Pellerin

Coupling a production scheduling process with maintenance logs can provide important advantages. For instance, this enables the adaptation of planning to the reality of the shop floor. Nevertheless, maintenance logs are often highly unstructured, as they mainly rely on free-form text comments from…

Enhance sentiment analysis on social networks with social influence analytics

Nadia Chouchani, Mourad Abed

Sentiment analysis on social networks has attracted increasing research attention. Most previous works rely on text mining and the phenomenon of Homophily reflected by explicit friendship relations, which are a weak assumption for modeling sentiment and opinion similarities. In this paper we show…
