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…

Behaviour of flow dynamics over an asymmetrical deep cavity at high reynolds numbers

Denis Cornu, Laurent Keirsbulck, Camila Chovet, Marc Lippert, Franck Kerhervé, Fethi Aloui

This paper presents an experimental study, based on the geometry of a cavity, about the flow effects using quantitative particle image velocimetry (PIV) and, local and instantaneous pressure measurements. Three configurations of rectangular deep cavities were investigated: symmetric and asymmetric…

FMRI Data Analysis Using Dempster-Shafer Method with Estimating Voxel Selectivity by Belief Measure

Abdelouahab Attia, Abdelouahab Moussaoui, Abdelmalik Taleb-Ahmed

In the functional Magnetic Resonance Imaging (fMRI) data analysis, detecting the activated voxels is a challenging research problem where the existing methods have shown some limits. We propose a new method wherein brain mapping is done based on Dempster-Shafer theory of evidence (DS) that is a…

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…

Exergy assessment of heat transfer inside a Beta type Stirling engine

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

This paper presents an assessment of both energy and exergy efficiencies of a Beta Stirling engine prototype with a 30 W capacity as the maximum mechanical power output. Its operating pressure is close to atmospheric pressure, and it supports a maximum hot end temperature of 650 degrees C. The…

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…

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…

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)…

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…
