Investigations of the microstructural response to a cold forging process of the 6082-T6 alloy

Jérémie Bouquerel, Bandiougou Diawara, André Dubois, Mirentxu Dubar, Jean-Bernard Vogt, Denis Najjar

The microstructure of 6082 aluminium alloy in artificial aged condition was investigated before and after cold forming. The cold forming process was performed at room temperature with and without lubricant. An in depth microstructure investigation has been carried out through electron backscatter…

Analysis of the unsteady behavior of an electrical heater using the lock-in technique: Comparison of theory and experiments

Sylvain Lalot, Bernard Desmet

In the recent years, the lock-in technique has been tested in thermal engineering. Due to its high sensitivity for signal analysis, it has great potentialities for drift detection. Here the aim is more particularly fouling detection. The key point for this technique is the choice of the angular…

Brightness versus roughness: a multiscale approach

Maxence Bigerelle, Julie Marteau, C Paulin

A link between roughness and brightness is sought for brass specimens that were superfinished, sandblasted and brushed. Only the blasting conditions are varied in order to get different roughness and brightness. First, a relation between roughness and brightness is sought for specimens that were…

Relation between surface hardening and roughness induced by ultrasonic shot peening

Julie Marteau, Maxence Bigerelle

This paper is focused on the identification of a relation between surface hardening and roughness induced by ultrasonic shot peening. A method that dissociates the influence of roughness from the value of the true macroscopic hardness is applied to AISI 316L stainless steel specimens treated using…

Controller Design for TS Models Using Delayed Nonquadratic Lyapunov Functions

Zsofia Lendek, Thierry-Marie Guerra, Jimmy Lauber

In the last few years, nonquadratic Lyapunov functions have been more and more frequently used in the analysis and controller design for Takagi-Sugeno fuzzy models. In this paper, we developed relaxed conditions for controller design using nonquadratic Lyapunov functions and delayed controllers and…

Wind potential evaluation around isolated pitched roof buildings

Nachida Bourabaa, Eric Delacourt, Jean-Luc Menet

The knowledge of wind field characteristics around buildings is very useful in a variety of applications such as energy supply by means of a domestic wind turbine. In this paper, results of a wind study around a conventional pitched roof building are given in order to choose the best location and…

Energy-aware manufacturing operations

Vittaldas V. Prabhu, Damien Trentesaux, Marco Taisch

This editorial introduces the special issue on energy-aware manufacturing operations in the International Journal of Production Research. The 12 papers in this special issue were selected because of their high quality and also because they deal with topics related to energy-aware manufacturing…

Switching mode control strategy in manufacturing execution systems

Theodor Borangiu, Silviu Răileanu, Thierry Berger, Damien Trentesaux

The paper describes a semi-heterarchical control solution for mixed planning and scheduling, routing and job execution in flexible manufacturing systems based on the paradigms of holonic manufacturing and product-driven automation. The main feature of the control solution is the bidirectional…

A variable neighborhood search for solving the multi-vehicle covering tour problem

Manel Kammoun, Houda Derbel, Mustapha Ratli, Bassem Jarboui

In this article, we consider a transportation problem with different kinds of locations: V , T, and W. The set T ⊂ V consists of vertices that must be visited through the use of potential locations in V and W consists of locations that must be covered. The problem consists in minimizing vehicle…

Clustering cities based on their development dynamics and Variable neigborhood search

B. S. Zhikharevich, O. V. Rusetskay, Nenad Mladenovic

Clustering cities based on their socio-economic development in long time period is an important issue and may be used in many ways, e.g., in strategic regional planning. In this paper we continue our recent study where cumulative attribute for each year replaces nine other attributes, called ‘…
