Solving the maximally diverse grouping problem by skewed general variable neighborhood search

Jack Brimberg, Nenad Mladenovic, Dragan Urošević

The maximally diverse grouping problem requires finding a partition of a given set of elements into a fixed number of mutually disjoint subsets (or groups) in order to maximize the overall diversity between elements of the same group. In this paper we develop a new variant of variable neighborhood…

Decomposition of a tribological system by chaos theory on rough surfaces

Maxence Bigerelle, Jean-Marie Nianga, A. Iost

The purpose of this paper is to analyze the turning machinability of a martensitic steel, according to the cutting speed, and through signal analyses of the morphology of the machined surface. We initially carried out the classification of a large number of parameters of roughness, on the basis of…

Variable neighborhood search for the economic lot sizing problem with product returns and recovery

Angelo Sifaleras, Ioannis Konstantaras, Nenad Mladenovic

The economic lot sizing problem with product returns and recovery is an important problem that appears in reverse logistics, and has recently been proved to be NP-hard. In this paper, we suggest a Variable Neighborhood Search (VNS) metaheuristic algorithm for solving this problem. It is the first…

Quantitative approach to determine the mechanical properties by nanoindentation test: Application on sandblasted materials

Y. Xia, Maxence Bigerelle, Salima Bouvier, Alain Iost, P.-E. Mazeran

A novel method is developed to improve the accuracy in determining the mechanical properties from nanoindentation curves. The key point of this method is the simultaneous statistical treatment of several loading curves to correct the zero point error and identify the material properties considering…

Effect of natural trunk inclination on variability in soleus inhibition and tibialis anterior activation during gait initiation in young adults

Annie-Pierre Fortin, Yoann Dessery, Sebastien Leteneur, Franck Barbier, Philippe Corbeil

Background Anticipatory postural adjustments (APAs) of gait initiation (GI) permit first step execution. APAs are characterized by a structured pattern of soleus (SOL) inhibition followed by tibialis anterior (TA) activation. This pattern shows variability among young adults where SOL is not always…

Flow rate distribution and effect of convection and radiation heat transfer on the temperature profile during a coil annealing process

Abdallah Haouam, Maxence Bigerelle

Determining the temperature of several steel coils, heated in a furnace with a controlled hydrogen environment is important in an annealing process. Temperatures must be defined during heat treatment in order to guarantee metallurgical properties and acceptable reduced residual stresses. In this…

Damage at high strain rates in semi-crystalline polymers

Romain Balieu, Franck Lauro, Bruno Bennani, Grégory Haugou, Fahmi Chaari, Tsukatada Matsumoto, Ernesto Mottola

A specific damage characterization method using Digital Image Correlation for semi-crystalline polymers is proposed for a wide range of strain rates. This damage measurement is an extension of the SEĖ method [16] which was developed to characterize the behaviour laws at constant strain rates of…

Active Control of Nonlinear Suspension System Using Modified Adaptive Supertwisting Controller

Jagat Jyoti Rath, Kalyana Chakravarthy Veluvolu, Michael Defoort

The suspension system is faced with nonlinearities from the spring, damper, and external excitations from the road surface. The objective of any control action provided to the suspension is to improve ride comfort while ensuring road holding for the vehicle. In this work, a robust higher order…

A numerical study of the evolution of the blast wave shape in rectangular tunnels

David Uystepruyst, François Monnoyer de Galland

When the explosion of condensed materials occurs in square or circular cross-section tunnel, the subsequent blast wave reveals two patterns: three-dimensional close to the explosive charge and one-dimensional far from the explosion. Pressure decays for these two patterns have been thoroughly…

Different surface sensing of the cell body and nucleus in healthy primary cells and in a cancerous cell line on nanogrooves

Patricia Davidson, Maxence Bigerelle, Gunter Reiter, Karine Anselme

Cancer cells are known to have alterations compared to healthy cells, but can these differences extend to the way cells interact with their environment? Here, the authors focused on the alignment on an array of grooves of nanometer depth using two cell types: healthy osteoprogenitor primary cells (…
