Solving the flexible job-shop just-in-time scheduling problem with quadratic earliness and tardiness costs

Gabriel Zambrano Rey, Abdelghani Bekrar, Damien Trentesaux, Binghai Zhou

The flexible job-shop scheduling problem is known to be an (Non-deterministic Polynomial-time hard) combinatorial problem and has become a challenge in optimization and manufacturing control. Although flexibility is important in order to respond effectively to higher product variety, shorter lead…

Scheduling operating theatres: Mixed integer programming vs. constraint programming

Tao Wang, Nadine Meskens, David Duvivier

The daily scheduling of an operating theatre is a highly constrained problem. In addition to standard scheduling constraints, many additional constraints on human and material resources encountered in real life should be taken into account. These constraints concern the priority of operations, the…

Scalable row-based parallel H.264 decoder on embedded multicore processors

Elias Michel Baaklini, Santhosh Kumar Rethinagiri, Hassan Sbeity, Smail Niar

Multimedia applications are present in most mobile hand-held devices, which are still equipped with limited battery resources. The H.264 standard is currently dominating the video compression world. H.264 has high computational requirements in terms of memory, energy, and time. Many techniques…

Thermocapillary instability in an evaporating two-dimensional thin layer film

Andriy A. Avramenko, Igor V. Shevchuk, Souad Harmand, Andrii I. Tyrinov

A novel two-dimensional model for the thermocapillary instability of a thin liquid film was developed and validated in the paper. The model incorporates a novel solution for the unperturbed velocity components and the thin film thickness (based on the boundary layer approach and balance equation)…

Comparison Based on Exergetic Analyses of Two Hot Air Engines: A Gamma Type Stirling Engine and an Open Joule Cycle Ericsson Engine

Houda Hachem, Marie Creyx, Ramla Gheith, Eric Delacourt, Céline Morin, Fethi Aloui, Sassi Ben Nasrallah

In this paper, a comparison of exergetic models between two hot air engines (a Gamma type Stirling prototype having a maximum output mechanical power of 500 W and an Ericsson hot air engine with a maximum power of 300 W) is made. Referring to previous energetic analyses, exergetic models are set up…

RFID interactive tabletop application with tangible objects: exploratory study to observe young children’ behaviors

Sébastien Kubicki, Marion Wolff, Sophie Lepreux, Christophe Kolski

Numerous academic and industrial studies and developments concerning interactive tabletops are paving the way for new educational applications. We have developed an interactive tabletop application equipped with RFID technology. This tabletop, called TangiSense, is based on a Multi-Agent System…

A two-stage flow shop scheduling problem with transportation considerations

Nacira Chikhi, Moncef Abbas, Rachid Benmansour, Abdelghani Bekrar, Said Hanafi

This paper considers a two-stage robotic flow shop scheduling problem of which the objective is to minimize the maximum completion time of all the jobs. The problem consists of two dedicated machines at the first stage and a single machine at the second stage. Each job is defined by two operations…

Framework for a Selection of Custom Instructions for Ht-MPSoC in Area-performance Aware Manner

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

Using application-specific instructions for heterogeneous multiprocessor system-on-chip (Ht-MPSoC) allows to find a good performance/energy trade-off. For MPSoC architecture executing different multimedia applications, we expect a large number of potential custom instructions. In order to explore…

Simplified soft output demapper for non-binary LDPC codes

Latifa Mostari, Abdelmalik Taleb-Ahmed, Abdennacer Bounoua

Combining non-binary LDPC codes and high order constellation, namely Bit-Interleaved Coded Modula-tion (BICM), is a simple but effective way to improve the bandwidth efficiency. Since the non-binary LDPCcodes require soft decisions as the input information, the constellation has to provide soft…
