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…

Use of the PIV and Electrochemical Techniques to Experimentally Characterize the Couette-Taylor- Poiseuille Flow Instabilities

Wafik Abassi, Fethi Aloui, Sassi Ben Nasrallah, Jack Legrand

The Taylor-Couette problem is a fundamental model in bifurcation theory and hydrodynamic stability. The inner cylinder rotation generates a flow pattern known by a transition to turbulence through a sequence of successive hydrodynamic instabilities. The effect of an imposed axial flow on the…

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…

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…

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…

Relationship between brightness and roughness of polypropylene abraded surfaces

Adrien van Gorp, Maxence Bigerelle, Denis Najjar

This article proposes to analyze the relation between gloss and roughness of surfaces of polypropylene samples abraded at different magnitudes. Experiments consist of mechanical polishing at different grades, roughness profiles measurement, and specular light reflectometry with three incidence…

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…

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…
