A novel DEM approach for modeling brittle elastic media based on distinct lattice spring model

Damien André, Jérémie Girardot, Cédric Hubert

The Discrete Element Method (DEM), also known as Distinct Element Method (DEM), is extensively used to study divided media such as granular materials. When brittle failure occurs in continuum such as concrete or ceramics, the considered media can be viewed as divided. In such cases, DEM offers an...

Influence of three different types of physical training programs on bone mineral density in a group of elderly subjects, Influence de trois différents types de programmes d'entraînement physique sur la densité minérale osseuse dans un groupe de sujets âgés

Riad Nasr, Nathalie Rassy, Eric Watelain, S. Ishac, Obaida Abdul Al, Rawad El Hage

Introduction The aim of the present study was to explore the effect of resistance, endurance, and combined exercise training on bone mass in a group of elderly subjects. Summary of facts and results Fifty-two healthy elderly subjects (35 women and 17 men) whose ages range between 65 and 75 years..., Introduction Le but de cette étude était d’explorer l’effet de l’entraînement physique en résistance, endurance ou bien combiné (aérobie et résistance) sur la masse osseuse dans un groupe de sujets âgés. Synthèse des faits et résultats Cinquante-deux sujets sains (35 femmes et 17 hommes) âgés de 65...

Effect of hydroxyl (OH) group position in alcohol on performance, emission and combustion characteristics of SI engine

Devaraj Jesu Godwin, Edwin Geo Varuvel, Shanmugam Thiyagarajan, M. Leenus Jesu Martin, T. Maiyalagan, C. G. Saravanan, Fethi Aloui

In this research work, an attempt has been made to compare the performance and emission characteristics of n-butanol (n-B), iso-butanol (Iso-B), n-pentanol (P) and benzyl alcohol (Bn) with gasoline at various load conditions in the ratio of 10:90 by volume respectively, in a 2 cylinder SI test...

How can the stimulation of plantar cutaneous receptors improve postural control? Review and clinical commentary

Frédéric Viseux, Antoine Lemaire, Franck Barbier, Pascal Charpentier, Sebastien Leteneur, Philippe Villeneuve

Postural control requires constant and subconscious postural sway to manage balance and achieve postural stability. These movements of regulation are based in particular on cutaneous plantar information. The foot constitutes a functional whole that participates in the mechanisms of postural control...

Ontology for cloud manufacturing based Product Lifecycle Management

Asma Talhi, Virginie Fortineau, Jean-Charles Huet, Samir Lamouri

The manufacturing environment has become increasingly competitive in the past few years, and product development is getting even more complex. The agility of an information system is a way to manage this complexity, and cloud technologies enable the sharing of tools and information in a new way. In...

Control strategy for fixed-time leader–follower consensus for multi-agent systems with chained-form dynamics

Pipit Anggraeni, Michael Defoort, Mohamed Djemai, Zongyu Zuo

This paper is concerned with the fixed-time consensus problem of multiple chained-form systems under matched perturbations. In this study, the leader (which can be dynamic) only transmits its state and control input to its neighbors. For each agent, a decentralized observer is designed to estimate...

Lane keeping of autonomous vehicles based on differential steering with adaptive multivariable super-twisting control

Chuan Hu, Yechen Qin, Haotian Cao, Xiaolin Song, Kai Jiang, Jagat Jyoti Rath, Chongfeng Wei

This paper investigates the lane keeping control for four-wheel independently actuated autonomous vehicles. To guarantee the vehicle safety when the active-steering motor entirely fails, the steering manoeuvre is realized by the differential drive assisted steering (DDAS) that is generated by the...

Nonlinear Tracking Control with Reduced Complexity of Serial Robots: A Robust Fuzzy Descriptor Approach

Thi van Anh Nguyen, Tran Anh-Tu Nguyen, Antoine Dequidt, Laurent Vermeiren, Michel Dambrine

This paper presents a nonlinear tracking con-trol approach for a two degrees of freedom (2-DoF) se-rial manipulator. The design goal is to achieve a guar-anteed H∞tracking performance while keeping the de-signed controller as simple as possible for real-time im-plementation. To this end, the...

Physically-based constitutive description of a commercial Al-Mg-Si alloy deformed under cold-warm working conditions

Kevin Le Mercier, Jean-Dominique Guerin, Mirentxu Dubar, Laurent Dubar, Eli Saúl Puchi-Cabrera

The experimental and numerical modeling of cold forging operations conducted on commercial Al alloys requires a precise knowledge of the functional dependence of both flow stress and work-hardening rate on microstructure and deformation conditions. In order to contribute to the improvement of the...
