Decay rate of the Timoshenko system with one boundary damping

Denis Mercier, Virginie Régnier

In this paper, we study the indirect boundary stabilization of the Timoshenko system with only one dissipation law. This system, which models the dynamics of a beam, is a hyperbolic system with two wave speeds. Assuming that the wave speeds are equal, we prove exponential stability. Otherwise, we...

A class of analytic pairs of conjugate functions in dimension three

Paul Baird, Elsa Ghandour

We exploit an ansatz in order to construct power series expansions for pairs of conjugate functions defined on domains of Euclidean 3-space. Convergence properties of the resulting series arc investigated. Entire solutions which are not harmonic are found as well as a 2-parameter family of examples...

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...

Lagrangian submanifolds of the nearly Kähler S3 × S3 from minimal surfaces in S3

Burcu Bektaş, Marilena Moruz, Joeri van Der Veken, Luc Vrancken

We study non-totally geodesic Lagrangian submanifolds of the nearly Kähler S3 × S3 for which the projection on the first component is nowhere of maximal rank. We show that this property can be expressed in terms of the so-called angle functions and that such Lagrangian submanifolds are closely...

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...

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...

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...

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...
