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…

Existence of a variational solution for the stationary Boussinesq equations with thermocapillary effect and nonhomogenous boundary conditions

Bernardin Ahounou, Luc Paquet

In this work, we prove the existence of at least one variational solution (u, θ, p) of the stationary Boussinesq equations with thermocapillary effect on the surface and nonhomogenous boundary conditions for the velocity and the temperature. We assume that the domain is plane, bounded and polygonal…

An Iterative Greedy Insertion Technique for Flexible Job Shop Scheduling Problem

Azzedine Bekkar, Oualid Guemri, Abdelghani Bekrar, Nassima Aissani, Bouziane Beldjilali, Damien Trentesaux

This paper studies the problem of scheduling in a flexible job shop. A greedy heuristic is developed to solve precisely the sequencing (allocation) problem. The principle of this approach is to iteratively insert operations on the machines until the objective of minimizing the Cmax (makespan) is…

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…

Advanced model based air path management using a discrete-angular controller in idle-speed context

Thomas Laurain, Jimmy Lauber, Reinaldo Martinez Palhares

This paper aims to present an original methodology to design a controller for the air path management considered as a nonlinear system that is presented as a periodic discrete Takagi-Sugeno (TS) model. A transformation is realized to translate the periodic behavior into a classic discrete model…

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…

Regularity of solutions of elliptic or parabolic problems with Dirac measures as data

S. Ariche, Colette De Coster, Serge Nicaise

In this paper we study the Laplace and heat equations with Dirac right-hand side. We prove some regularity results in a scale of weighted Sobolev spaces, the weight being the distance to the support of the right-hand side. Model situations in dimension three are treated by using Fourier, Laplace or…

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…
