Heating rate and ZSM-5 catalyst effects on date palm (Phœnix dactylifera L.) stones pyrolysis: Thermogravimetric analysis, production and characterization of syngases and bio-oils

Ilham Soltani, Emna Berrich, Mehrez Romdhane, Fethi Aloui

In the present investigation, Date palm stones (DPS) were pyrolyzed under Nitrogen atmosphere in a laboratory scale fixed-bed reactor. Pyrolysis experiments were carried out at different heating rates (5 and 10 °C/min), both in absence and presence of ZSM-5 catalyst (20 wt%). The effects of heating...

Deep learning for continuous parking occupancy forecasting in urban environments, Apprentissage profond pour la prévision continue de l’occupation du parking en milieu urbain

Miratul Khusna Mufida

Deep learning has been widely adopted in various fields for its ability to extract complex features from large amounts of data. In this thesis, we propose a deep learning-based approach for continuous parking occupancy prediction. We therefore collected a large dataset of parking occupancy data (..., L'apprentissage profond a été largement adopté dans divers domaines en raison de sa capacité à extraire des caractéristiques complexes à partir de grandes quantités de données. Dans cette thèse, nous proposons une approche basée sur l'apprentissage profond pour la prédiction continue de l...

2D Numerical Simulation of Downburst Simulator in the Wall of Wind

Guillaume Levieux, Amal Elawady, Arindam Chowdhury, Fethi Aloui

Downbursts are extremely spontaneous and dangerous phenomena that have been shown to be responsible for failures of many structural systems. The Wall of Wind team is currently in the process of developing a large-scale downburst simulator that could facilitate research to improve the resistance of...

Passive sensor network resycnhronization applied for SHM

O. Bouchakour, L. Chehami, E. Moulin

Recent research works in passive Structural Health Monitoring (SHM) have been able to take advantage of ambient noise by cross-correlating raw data recorded by sensor array. For that, the acquired signals must be synchronized with respect to each other. In other words, it is essential to set up a...

The morphology and evolution in Al-Cu and Al-Fe magnetic pulse weld interfaces characterized through phase-contrast micro-tomography, Morphologie et évolution des interfaces de magnéto-soudures (soudures par impulsion magnétiques) d'aluminium (Al) - Cuivre (Cu) et d'Al - Acier (Fe) caractérisées par micro-tomographie à contraste de phase

Benjamin Zielinski, Tarik Sadat, Bratislav Lukić, Alexander Rack, Eric Markiewicz, Laurent Dubar

Magnetic Pulse Welding (MPW) facilitates the permanent joining of dissimilar metallic materials through the sudden impact generated by a magnetic pulsed field. The process can introduce distinct morphological features at the interface of bi-material joints, which subsequently affect the joint'..., La soudure par impulsion magnétique ou magnéto-soudage (MPW - "Magnetic Pulse Welding) facilite la soudure permanente de matériaux dissimilaires au travers d'un impact brutal généré par un champ magnétique. Le procédé introduit des structures morphologiques très particulières à l'...

Observer design with exponential time-varying gain for Takagi–Sugeno fuzzy systems with continuous and aperiodic sampled outputs

Hiba Fawzia Bouchama, Michael Defoort, Jimmy Lauber, Denis Berdjag

In this paper, an observer with exponential time-varying gain is proposed for a class of nonlinear systems in Takagi–Sugeno form with both continuous-time and aperiodic sampled outputs. The proposed observer consists of two parts: one related to the continuous-time outputs and one related to the...

Reduced-order model based dynamic tracking for soft manipulators: Data-driven LPV modeling, control design and experimental results

Shijie Li, Tran Anh-Tu Nguyen, Thierry-Marie Guerra, Alexandre Kruszewski

We propose a generic nonlinear reduced-order tracking control method for elastic soft robots. To this end, a new linear parameter varying (LPV) control framework is developed using the data collected from the soft robots. Specifically, for LPV modeling we first derive a nonlinear robot model, which...

Minimal δ(2)-ideal Lagrangian submanifolds and the quaternionic projective space

Kristof Dekimpe, Joeri van der Veken, Luc Vrancken

We construct an explicit map from a generic minimal δ(2)-ideal Lagrangian submanifold of Cn to the quaternionic projective space HPn−1, whose image is either a point or a minimal totally complex surface. A stronger result is obtained for n=3, since the above mentioned map then provides a one-to-one...

Evaluating the Acceptance of a Software Application Designed to Assist Communication for People with Parkinson’s Disease

Julia Greenfield, Káthia Marçal de Oliveira, Véronique Delcroix, Sophie Lepreux, Christophe Kolski, Anne Blanchard-Dauphin

Parkinson’s disease (PD) is a neurodegenerative disorder that affects a huge number of people. People with PD may have trouble speaking. Impeded speech affects 70% of people with PD and this can have particularly harmful consequences linked to social exclusion and isolation. Considering this...
