Observer Based Leader–Follower Bipartite Consensus With Intermittent Failures Using Lyapunov Functions and Time Scale Theory

Subham Dey, Fatima Zohra Taousser, Mohamed Djemai, Michael Defoort, Stefano Di Gennaro

This letter introduces a distributed observer-based protocol to achieve bipartite leader-follower consensus for linear multi-agent systems under intermittent failures. Under possible failures in the measurement and control input channels, the consensus protocol is based on intermittent interaction...

Autonomous and non-autonomous fixed-time leader–follower consensus for second-order multi-agent systems

Miguel Angel Trujillo, Rodrigo Aldana-Lopez, David Gomez-Gutierrez, Michael Defoort, Javier Ruiz-León, Héctor Becerra

This paper addresses the problem of consensus tracking with fixed-time convergence, for leader–follower multi-agent systems with double-integrator dynamics, where only a subset of followers has access to the state of the leader. The control scheme is divided into two steps. The first one is...

Instrumented Analysis of the Sit-to-Stand Movement for Geriatric Screening: A Systematic Review

Brajesh Shukla, Jennifer Bassement, Vivek Vijay, Sandeep Yadav, David Hewson

The Sit-to-Stand (STS) is a widely used test of physical function to screen older people at risk of falls and frailty and is also one of the most important components of standard screening for sarcopenia. There have been many recent studies in which instrumented versions of the STS (iSTS) have been...

Immersion cooling effect of dielectric liquid and self-rewetting fluid on smooth and porous surface

Pin Chen, Souad Harmand, Safouene Ouenzerfi

Dielectric liquid Novec 7300 and 5% 1-butanol aqueous solution are applied for immersion cooling of heater in order to investigate effect of nucleate boiling and self-rewetting on heat transfer. Experimental results are compared with water as common liquid for immersion cooling. In first part of...

Effect of Physical Challenging Activity on Tactile Texture Recognition for Mobile Surface

Adnane Guettaf, Yosra Rekik, Laurent Grisoni

Previous research demonstrated the ability for users to accurately recognize tactile textures on mobile surface. However, the experiments were only run in a lab setting and the ability for users to recognize tactile texture in a real-world environment remains unclear. In this paper, we investigate...

Machine learning for demand forecasting in the physical internet: a case study of agricultural products in Thailand

Anirut Kantasa-Ard, Maroua Nouiri, Abdelghani Bekrar, Abdessamad Ait El Cadi, Yves Sallez

Supply chains are complex, stochastic systems. Nowadays, logistics managers face two main problems: increasingly diverse and variable customer demand that is difficult to predict. Classical forecasting methods implemented in many business units have limitations with the fluctuating demand and the...

Postural instability in Parkinson’s disease: Review and bottom-up rehabilitative approaches

Frédéric Viseux, Arnaud Delval, Luc Defebvre, Martin Simoneau

The aims of this narrative review are to provide scientific support to characterize the postural instability commonly observed in Parkinson's disease (PD), and to emphasize how bottom-up rehabilitation programs stimulating the sole of the foot can improve postural stability in PD. Postural...

A comparative analysis of different methods to improve the performance of rubber seed oil fuelled compression ignition engine

Edwin Geo Varuvel, Govindan Nagarajan, Fethi Aloui, Mohand Tazerout

There is a need to find suitable substitutes for the petroleum based fuels as the conventional fuels are decreasing in order in recent years. Vegetable oils are attractive as an alternative fuel for diesel engines as they are renewable and can be used in engines without employing any major...

Local stabilization of discrete-time nonlinear systems

Zsofia Lendek, Jimmy Lauber

This paper considers local stability analysis and local stabilization of discrete-time nonlinear systems represented by Takagi-Sugeno fuzzy models. Conditions are established using Lyapunov functions and controller gains that depend also on past samples. Together with the stability and design...
