Experimental investigation of early strain heterogeneities and localizations in polycrystalline α -Fe during monotonic loading

Adrien Berger, Jean-Francois Witz, Ahmed El Bartali, Tarik Sadat, Nathalie Limodin, Mirentxu Dubar, Denis Najjar

A polycrystalline recrystallized α-Fe specimen was subjected to monotonic tension up to 2 % strain. Local strain was measured all over the width of the specimen thanks to in-situ optical-based Digital Image Correlation with adequate spatial and temporal resolution. With additional knowledge of...

Short-Term Load Forecasting Based on CNN and LSTM Deep Neural Networks

First Ali Agga, Second Ahmed Abbou, Yassine El Houm, Moussa Labbadi

In the coming years, the world will witness a global transition towards the adoption of photovoltaic technology for large-scale plants to produce electricity at a grid scale, and more householders will also be encouraged to produce their electricity. However, the reliance of the photovoltaic plants...

Online driver model parameter identification using the Lyapunov approach based shared control

Mohamed Radjeb Oudainia, Chouki Sentouh, Anh-Tu Nguyen, Jean-Christophe Popieul

The work described in this paper proposes a new conflict minimisation strategy in shared driving control for lane keeping systems (LKS) in intelligent vehicles. This strategy takes into account a dynamic driver model, where the driver’s parameters are identified online using the Lyapunov approach...., Le travail décrit dans cet article propose une nouvelle stratégie de minimisation des conflits dans le contrôle partagé de la conduite pour les systèmes de maintien de voie (LKS) dans les véhicules intelligents. Cette stratégie prend en compte un modèle de conducteur dynamique, où les paramètres du...

An exact approach to the integration of non-cyclical preventive maintenance scheduling and production planning for a series-parallel production system

Abdessamad Ait El Cadi, Nizar Elhachemi, Abdelhakim Artiba, Mohamed Anouar Jamali, Louis-Martin Rousseau

In this paper, we generalise a model for integrated noncyclical preventive maintenance scheduling and production planning from a single machine to a series-parallel production line. As for a single machine, we consider a set of products that must be produced in lots during a given time horizon. The...

An Analysis of the Security and Privacy Issues of the Neovote Online Voting System

Enka Blanchard, Antoine Gallais, Emmanuel Leblond, Djohar Sidhoum-Rahal, Juliette Walter

Abstract This article provides the first security and privacy analysis of the Neovote voting system, which was used for three of the five primaries in the French 2022 presidential election. We show that the demands of transparency, verifiability and security set by French governmental organisations...

Theories of Global Collapse: Closing Down or Opening Up the Futures?

Fabrizio Li Vigni, Enka Blanchard, Cyprien Tasset

In this essay, we first ask what kind of rhetorical styles the theories of global collapse have when talking about futures. We claim that these theories manifest in one of three forms: prospective, prophecy, and science-fiction. We then ask if such theories tend to close down or rather open up the...

Numerical prediction of the galling of aluminium alloys in cold strip drawing

Oussama Filali, André Dubois, Marcel Moghadam, Chris V Nielsen, Laurent Dubar

A methodology based on finite element computations is proposed to predict the galling onset of aluminium alloys in cold forming. The methodology assumes that galling starts as soon as a finite element in the area of contact has reached a critical damage. The damage is calculated using Xue's...

Heuristic and exact reduction procedures to solve the discounted 0–1 knapsack problem

Christophe Wilbaut, Raca Todosijevic, Saïd Hanafi, Arnaud Fréville

In this paper we consider the discounted 0–1 knapsack problem (DKP), which is an extension of the classical knapsack problem where a set of items is decomposed into groups of three items. At most one item can be chosen from each group and the aim is to maximize the total profit of the selected...

Numerical and experimental investigations into the rheological behaviour of wet foam flowing under a fence

Heni Dallagi, Fethi Aloui, Laurent Bouvier, Laurent Wauquier, Thierry Benezech

Experimental and numerical investigations were carried out to describe the flow of a wet foam under a fence placed in the middle of a horizontal duct with a square crosssection. The aim was to characterize the foam’s flow behaviour and model it using CFD in complex geometrical situations such as...

Sample Entropy as a Tool to Assess Lumbo-Pelvic Movements in a Clinical Test for Low-Back-Pain Patients

Paul Thiry, Olivier Nocent, Fabien Buisseret, William Bertucci, André Thevenon, Emilie Simoneau-Buessinger

Low back pain (LBP) obviously reduces the quality of life but is also the world’s leading cause of years lived with disability. Alterations in motor response and changes in movement patterns are expected in LBP patients when compared to healthy people. Such changes in dynamics may be assessed by...
