Experimental and theoretical investigation of Stirling engine heater: Parametrical optimization

Ramla Gheith, Houda Hachem, Fethi Aloui, Sassi Ben Nasrallah

The aim of this work is to optimize γ Stirling engine performances with a special care given to the heater. This latter consists of 20 tubes in order to increase the exchange area between the working gas and the hot source. Different parameters were chosen to evaluate numerically and experimentally…

Prostate contours delineation using interactive directional active contours model and parametric shape prior model

Foued Derraz, Gérard Forzy, Arnaud Delebarre, Abdelmalik Taleb-Ahmed, Mourad Oussalah, Laurent Peyrodie, Sebastien Verclytte

Prostate contours delineation on Magnetic Resonance (MR) images is a challenging and important task in medical imaging with applications of guiding biopsy, surgery and therapy. While a fully automated method is highly desired for this application, it can be a very difficult task due to the…

New heuristic for harmonic means clustering

Emilio Carrizosa, Abdulrahman Al-Guwaizani, Pierre Hansen, Nenad Mladenovic

It is well known that some local search heuristics for K-clustering problems, such as k-means heuristic for minimum sum-of-squares clustering occasionally stop at a solution with a smaller number of clusters than the desired number K. Such solutions are called degenerate. In this paper, we reveal…

Solving the planar p-median problem by variable neighborhood and concentric searches

Zvi Drezner, Jack Brimberg, Nenad Mladenovic, Said Salhi

Two new approaches for the solution of the p-median problem in the plane are proposed. One is a Variable Neighborhood Search and the other one is a concentric search. Both approaches are enhanced by a front-end procedure for finding good starting solutions and a decomposition heuristic acting as a…

Hardware resource utilization optimization in FPGA-based Heterogeneous MPSoC architectures

Bouthaina Dammak Masmoudi, Mouna Baklouti, Rachid Benmansour, Smail Niar, Mohamed Abid

Next generation FPGA circuits will allow the integration of dozens of hard and soft cores as well as dedicated accelerators in the same chip. These Heterogeneous Multiprocessor System-on-Chip (Ht-MPSoC) architectures will allow the design of very complex System-on-Chips (SoC) on a single FPGA chip…

Study of the parameters and characteristics of flat heat pipe with nanofluids subjected to periodic heat load on its performance

Hamdy Hassan, Souad Harmand

A study is presented on the transient cooling of an electronic component by flat heat pipe (FHP) with nanofluid. The electronic component has periodic power output of maximum value 400 W and works for 12.8 s. The effects of Cu, CuO and Al2O3 nanoparticles on the heat pipe performance are…

Multi-objective variable neighborhood search: an application to combinatorial optimization problems

Abraham Duarte, Juan Pantrigo, Eduardo G Pardo, Nenad Mladenovic

Solutions to real-life optimization problems usually have to be evaluated con-sidering multiple conflicting objectives. These kind of problems, known as multi-objectiveoptimization problems, have been mainly solved in the past by using evolutionary algo-rithms. In this paper, we explore the…

Reactive control of overall power consumption in flexible manufacturing systems scheduling: A Potential Fields model

Cyrille Pach, Thierry Berger, Yves Sallez, Damien Trentesaux

In recent years, designing “energy-aware manufacturing scheduling and control systems” has become more and more complex due to the increasing volatility and unpredictability of energy availability, supply and cost, and thus requires the integration of highly reactive behavior in control laws. The…

Customizing VLIW processors from dynamically profiled execution traces

Gorker Alp Malazgirt, Arda Yurdakul, Smail Niar

The design philosophy of VLIW processors is to maximize instruction level parallelism (ILP) starting from compiler and machine code level to all the way down to memory and computational blocks. For this purpose, VLIW tailoring has been an important research area, because non-tailored VLIWs cannot…
