Wear pattern on a retrieved Total Knee Replacement: The “fourth body abrasion”

Charles Garabédian, Maxence Bigerelle, Denis Najjar, Henri Migaud

Released debris in a replaced knee, such as bone loose, bone cement debris and metallic particles, are responsible for a third body abrasion of the Polyethylene (PE) mobile bearing superior surface and therefore compromise the Total Knee Replacement (TKR) implant longevity. To analyze the upstream…

Urban legends in gait analysis

Paul Allard, Sebastien Leteneur, Eric Watelain, Mickaël Begon

Impaired gait patterns are often compared to that of a group of able-bodied subjects. This latter group usually forms a gold standard. Variability in able-bodied gait parameters could reflect different normal locomotion patterns. Furthermore, a lack of statistical difference between patient data…

Nopol: Automatic Repair of Conditional Statement Bugs in Java Programs

Jifeng Xuan, Matias Martinez, Favio Demarco, Maxime Clément, Sebastian Lamelas, Thomas Durieux, Daniel Le Berre, Martin Monperrus

We propose NOPOL, an approach to automatic repair of buggy conditional statements (i.e., if-then-else statements). This approach takes a buggy program as well as a test suite as input and generates a patch with a conditional expression as output. The test suite is required to contain passing test…

Experimental study of the cooling performance of phase change material with discrete heat sources – Continuous and intermittent regimes

Salma Gharbi, Souad Harmand, Sadok Ben Jabrallah

This paper presents an experimental investigation of phase change material (PCM, Plastic paraffin) behavior in a rectangular enclosure with three discrete heat sources flush-mounted on the right vertical wall. The remaining walls of the cavity are adiabatic. Maximizing the critical time (time…

Refinements of some Pachpatte and Bihari inequalities on time scales

Bacem Ben Nasser, Khaled Boukerrioua, Michael Defoort, Mohamed Djemai, Mohamed Ali Hammami

In this study, some generalizations and refinements of some inequalities of Pachpatte and Bellman-Bihari types are established on arbitrary time domains using the time scale theory. The obtained results unify continuous and discrete inequalities and extend some results known in the literature. The…

Towards increased systems resilience: New challenges based on dissonance control for human reliability in Cyber-Physical&Human Systems

Frédéric Vanderhaegen

This paper discusses concepts and tools for joint human and cyber-physical-systems analysis and control in the view of increasing the whole system resilience. More precisely, it details new challenges for human reliability based on dissonance control of Cyber-Physical&Human Systems (CPHS) to…

Quantitative analysis of galling in cold forging of a commercial Al-Mg-Si alloy

Kevin Le Mercier, Mirentxu Dubar, Katia Mocellin, André Dubois, Laurent Dubar

Multiple upsetting-sliding tests are performed at sliding velocities in the range of 20-200 mm.s-1 and at different plastic deformations to reproduce the local contact conditions experienced at the tool/workpiece interface during cold forging of a 6082 aluminium alloy. An original approach, able to…

An Improved Downlink MC-CDMA System for Efficient Image Transmission

Mohammed Sofiane Bendelhoum, Ali Djebbari, Ismail Boukli Hacene, Abdelmalik Taleb-Ahmed

Image compression is an essential stage of the data archiving and transmitting process, as it reduces the number of bits and the time required to complete the transmission. In this article, a study of image transmission over the Multi-Carrier Code Division Multiple Access (MC-CDMA) downlink system…

Asymptotically necessary and sufficient conditions for Takagi–Sugeno models using generalized non-quadratic parameter-dependent controller design

Raymundo Márquez Borbόn, Thierry-Marie Guerra, Miguel Bernal, Alexandre Kruszewski

Results in this paper generalize recent approaches on non-quadratic controller design for Takagi–Sugeno models based on a matrix transformation. Conditions thus obtained depend on a single parameter which allows an efficient search of feasible solutions via linear matrix inequalities; moreover,…
