Le présent mémoire a pour objective d’étudier la convection forcée en régime turbulent dans une portion d’échangeur de chaleur de type courant croisée grâce au logiciel de calcul numérique (CFD) Fluent, on rappel de l’enjeu ...
Cementitious matrices made up with mineral addition were the subject of many studies. However, no rule has yet been found to quantify the effects of such additions, against the performance of mortars, as the mixing of ...
Our work relates to the study of electric machines used for the production of electricity by using wind energy, we are interested in our thesis in the study of the doubly fed induction machine (DFIM) because this type of ...
The main objective of this work is to study the impact behavior composite
materials and their behavior more precisely the impact of the ball by the method of
planning experiments. The studied materials are laminated to ...
Les pipes métalliques sont particulièrement sensibles aux contraintes internes et externes ou instabilité géométrique, et leur dimensionnement s'opère en ayant recours à des règles simplifiées. En effet ces pipes sont très ...
Because of the specificities of self-compacting concrete (SCC), especially regarding their high volume paste content and the presence of large amounts of mineral admixtures and substitutes, the behaviour in fresh and ...
This project is a part of the industrial informatics research that focuses on the tools development and software platforms for dynamic production management. This is to set up a Web technology to a production management ...
With the progress realized in domains as the aeronautics, appeared the possibility to embark devices of communication on planes, on cars etc.... The idea to use the technology of microstrips as antennas allowed to bring ...
The vulnerability of the national territory with respect to the seismic phenomena and the levels of possible hazards that this one presents, particularly in the areas of the north of the country, are a fact established by ...
Linear Dimension Reduction method (LDR) is a classification technique, based on space
projections. It is considered as an alternative technique to principal component analysis and region of
interest methods. These latter ...
The networks of urban traffic have become complex and jammed up. In this respect, the numerical simulation by means of developed models, especially, in the western countries, is currently the panacea to optimize the ...
The work presented focuses on the numerical simulation of laminar natural convection in a closed square cavity, with a partially heated wall using the new method of lattice Boltzmann (LBM). First, a detailed study of the ...
The unavailability of human vertebrae for experiments requiring research
models identical to the real, made with other materials that have the same
mechanical properties as that of the bone.
Since the intervertebral ...

Récemment, l'utilisation des adhésifs est acceptée comme un processus de réparation des structures pour augmenter la durée de vie des composants endommagés. Le patch permet la redistribution alternative de contraintes; ...
The reliability of electronic components for automobile traction is a sensitive point of
their development and therefore the technological growth of electric vehicles. Due to their
mode operate and their environment, ...
