9 ABSTRACT This experimental work was performed to study the effect of some parameters on the behaviour of a soil under monotonic and cyclic loading. It includes four parts: The first part includes a bibliographical ...
ETUDE EXPERIMENTALE DU COMPORTEMENT MECANIQUE DE L’ACIER FAIBLEMENT ALLIE 42CD4

CHAOUCH Djamel (2012-01-16)

The aim of this study is to analyse the mechanical properties of low alloy steel 42CrMo4, used for the manufacture of bolts and threaded roads by Oil Company. We consider an experimental approach based on tensile, impact ...
COMPORTEMENT Á L’USURE DES MATÉRIAUX DE CONSTRUCTION MÉCANIQUE SOUS L’EFFET DES FACTEURS ENVIRONNEMANTAUX

KAID-AMEUR Djilali (2012-09-03)

We tried to approach this work with as near as possible the influence of the most imposing of wear such as speed, applied load and nature of building materials mechanical parts called "antagonistic" or contact in the ...
FORMULATION ET TENUE AU FEU DES MATÈRIAUX CIMENTAIRES RENFORCÉS DE FIBRES DE DIFFÉRENTES NATURES

Ezziane Mohammed (2012-09-30)

At room temperature, the addition of steel fibres in mortar conducts to an increase of mechanical strength and ductility. Exposed to high temperatures, a cement based material undergoes deterioration to a greater or lesser ...
MISE AU POINT D'UN TRAITEMENT DE CONVERSION DE SURFACE PAR DIFFUSION PRECIPITATION

AISSAT Sahraoui (2012-12-06)

This present work concerns the development of an indirect method to produce chromium carbide coatings known for their properties of wear, corrosion and oxidation resistance and that by the combination of a treatment of ...
Analyse numérique de la convection dans les conduits a rangée de plaques chauffées

BERIACHE M'hamed (2012-12-06)

The rapid development of technologies related to microprocessors, already achieves several GHz, while reducing the size of microchips. Therefore, the flux density of heat generated by these circuits is constantly increasing, ...

Analyse de la variabilité du rythme cardiaque pour l’évaluation du système nerveux autonome « Etude de cas physiologique »

Daoud Mohamed (2014-02-13)

The heart rate variability (HRV) is defined as the fluctuation time-series in the beat-to-beat RR-intervals, calculated from the electrocardiogram (ECG), is a key indicator of an individual’s cardiovascular condition. ...
ÉTUDE DES PHÉNOMÈNES DE TRANSPORT DANS LES CRISTAUX PHOTONIQUES À DÉSORDRE CORRÉLÉ

CHERID Samira (2014-06-03)

Using the transfer-matrix technique and the kronig Penney model, we numerically and analytically investigate the effect of short-range correlated disorder in random dimer model (RDM) on transmission properties of light in ...
Etude des propriétés optoélectroniques et magnétiques du semiconducteur CdTe à désordre corrélé

ZITOUNI ALI (2014-11-19)

In this work, we performed ab-initio calculations using the method of plane waves full potential linearized augmented (FP- LAPW) based on the theory of density functional theory (DFT) to determine the structural, electronic ...
MEMBRANE BASED INTEGRATED ANAEROBIC-AEROBIC PROCESS FOR THE TREATMENT OF TEXTILE WASTEWATER

BOUHADJAR, SAADIA- ILHEM (2015)
