Some improvements for determining the hardness of homogeneous materials from the work-of-indentation

Didier Chicot, Michel Yetna N'Jock, Francine Roudet, Xavier Decoopman, Mariana H. Staia, Eli Saúl Puchi-Cabrera

In this work, the total and plastic hardness of a variety of materials were determined from the work-of-indentation. We show that by taking into account the influence of the tip defect, both the total and plastic hardness have the same values and that the hardness-load dependence is considerably…

Spatial Resolution Correction for Electrochemical Wall-shear Stress Measurements using Rectangular Sensors

Fawzi Fadla, Rogelio Chovet, Denis Cornu, Marc Lippert, Fethi Aloui, Laurent Keirsbulck

This article is mainly motivated by the growing needs for highly resolved measurements forwall-bounded turbulent ﬂows and aims to proposes a spatial correction coefﬁcient in order toincrease the wall-shear stress sensors accuracy. As it well known for the hot wire anemometry, theﬂuctuating…

Behaviour of flow dynamics over an asymmetrical deep cavity at high reynolds numbers

Denis Cornu, Laurent Keirsbulck, Camila Chovet, Marc Lippert, Franck Kerhervé, Fethi Aloui

This paper presents an experimental study, based on the geometry of a cavity, about the flow effects using quantitative particle image velocimetry (PIV) and, local and instantaneous pressure measurements. Three configurations of rectangular deep cavities were investigated: symmetric and asymmetric…

A framework for supporting the choice of usability evaluation methods for interactive adaptive systems

Amira Dhouib, Neji Mahmoud, Abdelwaheb Trabelsi, Christophe Kolski

The evaluation of interactive adaptive systems is considered as a difficult endeavour due to the complex nature of these systems. Issues arise in the need to identify, for a given evaluation situation the set of suitable usability evaluation methods to be used by the evaluators. This paper…

Hybrid DCT-DBT algorithm for medical video compression

Yassine Habchi, Mohammed Beladgham, Haouari Benlabbes, Abdelmalik Taleb-Ahmed

In this paper we present the effect of transform type in medical video compression. To obtain the maximal capabilities of storage and transmission, different compression algorithms should be compared to find the optimal technique for medical video compression. We use for compression three type of…

An approach to the prioritization of sustainable maintenance drivers in the TBL framework

Sandro de Paula Pires, Olivier Sénéchal, Eduardo Rocha Loures, José Fernando Jimenez

The current sustainable production model is supported by the Triple Bottom Line (TBL) concept and its three dimensions: economic, environmental, and social. This paper aims to propose an approach to identify and prioritize the attributes of the TBL dimensions, extracted from the Global Reporting…

Finding a stabilizing switching law for switching TS models

Zsofia Lendek, Paula Raica, Jimmy Lauber, Thierry-Marie Guerra

This paper considers the stabilisation of switching nonlinear models by switching between the subsystems. We assume that arbitrary switching between two subsystems is possible once a subsystem has been active for a predefined number of samples. We use a Takagi–Sugeno representation of the models…

Modelling Laminate Failure in Composite Materials for Automotive Applications

David Moncayo, F. Köster, Pedro P Camanho, Daniel Coutellier, S. Hartmann

In order to capture the complexity of material failure it is necessary to understand that the performance of FE models depends on a fair use and a fair modeling of composite materials. Based on previous research works, the prognosis capabilities of the current material definitions in LS-DYNA will…

Integer Programming Based Approaches for Multi-Trip Location Routing

Rita Macedo, Cláudio Alves, José Valério De Carvalho, Said Hanafi, Nenad Mladenovic, Bruna Ramos

The multi-trip location routing problem consists in selecting the depots to open and the routes that should be performed to serve a set of clients at minimum cost. The multi-trip variant considers the possibility for a vehicle to perform more than a single route during the planning period, and…
