Multimodal Evaluation of the Spatio-Temporal Variations of Periprosthetic Bone Properties

Manon Fraulob, Sophie Le Cann, Benjamin Voumard, Hirokazu Yasui, Keita Yano, Romain Vayron, Mami Matsukawa, Philippe Zysset, Guillaume Haiat

Titanium implants are widely used in dental and orthopedic surgery. However, implant failures still occur because of a lack of implant stability. The biomechanical properties of bone tissue located around the implant need to be assessed to better understand the osseointegration phenomena and...

Experimental characterization and micromechanical modeling of the elastic response of the human humerus under bending impact

Jamila Rahmoun, Hakim Naceur, Hervé Morvan, Pascal Drazetic, Christian Fontaine, P.-E. Mazeran

This paper investigates the characterization and numerical modeling of the elastic behavior of the human humerus bone using a recently developed micromechanical approach coupled to nanoindentation measurements. At first, standard three-point bending experiments were conducted under low static...

Quantitative ultrasound assessment of the influence of roughness and healing time on osseointegration phenomena

Manon Fraulob, Romain Vayron, S. Le Cann, Benoît Lecuelle, Yoann Hériveaux, Hugues Albini Lomami, Charles-Henri Flouzat-Lachaniette, G. Haiat

The evolution of bone tissue quantity and quality in contact with the surface of orthopedic and dental implants is a strong determinant of the surgical outcome but remains difficult to be assessed quantitatively. The aim of this study was to investigate the performance of a quantitative ultrasound...

Predefined-time stabilisation of a class of nonholonomic systems

Juan Diego Sanchez-Torres, Michael Defoort, Aldo-Jonathan Muñoz-Vázquez

This paper deals with the predefined-time stabilisation problem for a class of uncertain chained-form nonholonomic systems. Based on a novel generalised Lyapunov-like characterisation of predefined-time stability, new predefined-time controllers are introduced for a class of first and second order...

Multi‐agent system for the reactive fleet maintenance support planning of a fleet of mobile cyber–physical systems

John William Mbuli, Tarik Chargui, Damien Trentesaux, Abdelghani Bekrar, Thierry Dailly

Improving the availability and reliability of a fleet of mobile cyber–physical systems as well as the ability to adapt themaintenance planning decisions when facing unexpected events at the fleet level is a major stake faced by the manufacturersand the operators. In the context of this study, the...

An efficient heuristic for a hub location routing problem

Mustapha Ratli, Dragan Urošević, Abdessamad Ait El Cadi, Jack Brimberg, Nenad Mladenovic, Raca Todosijević

This paper examines a new model for hub location known as the hub location routing problem. The problem shares similarities with the well studied uncapacitated single allocation p-hub median problem except that the hubs are now connected to each other by a cyclical path (or tour) known as the...

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...
