Failure mechanisms in chip-metallization in power applications

Camille Durand, Markus Klinger, Daniel Coutellier, Hakim Naceur

Degradation of the chip-metallization layer in power electronic packages under Active Power Cycling is still a major reliability concern. During Active Power Cycling tests, the chip acts as a heat source and temperature gradients develop within the package inducing stress and plastic deformation in…

Widgets Dedicated to User Interface Evaluation

Selem Charfi, Abdelwaheb Trabelsi, Houcine Ezzedine, Christophe Kolski

In this article, evaluation-based widgets are proposed as a contribution to assist evaluators for early evaluation of user interfaces. This contribution imbricates the ergonomic quality evaluation process into widgets used for user-interface graphical composition. In other words, these widgets…

Non-associated viscoplasticity coupled with an integral-type nonlocal damage model for mineral filled semi-crystalline polymers

Romain Balieu, Franck Lauro, Bruno Bennani, Tsukatada Matsumoto, Ernesto Mottola

A non-associated viscoplastic model coupled with nonlocal damage under finite strain framework is developed to simulate the non-isochoric deformation and the damage process exhibiting strain-softening of a 20% mineral filled semi-crystalline polymer. The logarithmic spin tensor properties linking…

Control predictor con ponderación de retardos: análisis de prestaciones y robustez ante retardo variable, Weighted-delay predictor-based control: Performance and robustness analysis with time-varying delay

Antonio González, Antonio Sala

Los controladores basados en predictor, en particular los obtenidos por métodos de asignación finita de espectro (también conocido como método de reducción), permiten abordar el control por realimentación del estado de sistemas con retardos constantes y conocidos a partir de un modelo equivalente…, Predictor-based controllers, in particular those obtained by Finite Spectrum Assignment (a.k.a. reduction) method, allow controlling systems with constant and known delays by using an equivalent delay-free model. However, if delay is time-varying or there exist uncertainties in the process model,…

Geometrically nonlinear analysis of thin-walled structures using efficient Shell-based SPH method

Jun Lin, Hakim Naceur, Daniel Coutellier, Abdel Laksimi

In this paper a shell-based meshless formulation is proposed for the geometrically nonlinear analysis of thin-walled structures using an explicit dynamics scheme based on the Smoothed Particle Hydrodynamics (SPH) method. In the present investigation the SPH method is modified to deal with shell-…

Reactive and energy-aware scheduling of flexible manufacturing systems using potential fields

Cyrille Pach, Thierry Berger, Yves Sallez, Thérèse Bonte, Emmanuel Adam, Damien Trentesaux

This paper presents a reactive scheduling approach for flexible manufacturing systems, which integrates the overall energy consumption of the production. This work is justified by the growing needs of manufacturers for energy-aware control, due to new important environmental criteria, which holds…

High-gain observer with sliding mode for nonlinear state estimation and fault reconstruction

Kalyana Chakravarthy Veluvolu, Michael Defoort, Yeng Chai Soh

This paper develops a high gain observer with multiple sliding modes for simultaneous state and fault estimations for MIMO nonlinear systems. The novelty lies in the observer design that employs the combination of high-gain observer and sliding mode observer. The proposed observer does not impose…

Is co-contraction responsible for the decline in maximal knee joint torque in older males?

Maxime Billot, Julien Duclay, Emilie Simoneau-Buessinger, Yves Ballay, Alain Martin

While it is often reported that muscular coactivation increases with age, the mechanical impact of antagonist muscles, i.e., the antagonist torque, remains to be assessed. The aim of this study was to determine if the mechanical impact of the antagonist muscles may contribute to the age-related…

Higher‐order sliding mode observer for estimation of tyre friction in ground vehicles

Jagat Jyoti Rath, Kalyana Chakravarthy Veluvolu, Michael Defoort, Yeng Chai Soh

The estimation of friction coefficient for a vehicle when it traverses on different surfaces has been an important issue. In this work, the longitudinal vehicle dynamics, the torsional tyre dynamics and the non-linear LuGre friction dynamics are integrated to model the quarter vehicle dynamics. The…

A comparison of rigid registration methods for prostate localization on CBCT and the dependence on rectum distension

Christine Boydev, David Pasquier, Foued Derraz, Laurent Peyrodie, Abdelmalik Taleb-Ahmed, Jean-Philippe Thiran

We evaluated automatic three-dimensional intensity-based rigid registration (RR) methods for prostate localization on CBCT scans and studied the impact of rectum distension on registration quality. 106 CBCT scans of 9 prostate patients were used. Each one was registered to the planning computed…
