Our work is oriented in the context of research on microsystems MEMS meaning:
systems Micro-Electro-Mechanical Systems. A microsystem is primarily a small system
including sensors, actuators and electronics designed to ...
La détermination du transfert de chaleur et des caractéristiques des écoulements générés par les forces d’Archimède dans des cavités est un problème dont l’intérêt tant sur le plan fondamental qu’au niveau des applications ...
Heritage is an identity at the time of a company and must be maintained as a
descriptive element of its cultural environment, allowing its conservation and transmission to
future generations.
The vulnerability is the ...
The natural and anthropic disasters which have occurred in the last few years caused enormous losses for populations, buildinge and other infrastructures (communication and transport networks ), to human activities (economic ...
Delayed ettringite formation (DEF) is a pathology of cementitious materials that has been widely studied these past years. If ettringite forms only partially during the beginning of cement hydration (its solubility increases ...
Transport infrastructure represents the balance between spatial planning and national strategic priorities in the short, medium and long term. This implies the urgent need to redefine some approaches to review the compatibility ...
The hydrogen embrittlement (HPF) of metallic materials is a problem particularly relevant
technological and scientific although its detection is relatively old.
Because of this crucial problem, the petrochemical and ...
The cardiovascular signals are, in general, quasi-periodicals with one period
which is not strictly constant. These variations are due to the action of the
autonomous nervous system (SNA).The first confronted problem is ...
Millions of cubic meters of sediment are dredged each year in the dams and deductions as a procedure of maintenance and prevention through the countries of the world .These sediments dredged ,considered as natural waste ...
Several studies were realized on the swelling phenomena of soils. This phenomenon which still remains non controllable, cause great damages on buildings all throughout the world. All the investigations done till now, have ...
The aim of this research consists firstly in studying the different steps to design
a cantilevered structure.
Secondly heat transfer law is adapted in order to analyse the temperature
distribution in a box-girder ...
The work presented in this thesis is related to the studies of laminar natural convection in a horizontal cylindrical tank of storage of the cryogenic fluids. This study is relative to a twodimensional simulation of a ...
Like any concrete structure, casing bridges experiencing significant damage that can affect the life of the structure. To address these shortcomings, researchers have ceased trying to find solutions for the maintenance and ...
The composite laminates have found widespread applications in various fields of construction such as aerospace, marine, and automotive. The high stress due to the discontinuity or sudden change of geometry is known under ...
In recent decades, many buildings in Algeria were made of reinforced concrete. The structures, in general, and the bridges, in particular, are subject to several chemical and mechanical reactions that can alter and influence ...
During the evaluation of a deck slab , the application of inappropriate
dynamic amplification factors could have significant implication .
The dynamic Response of a deck slab only depended on many factors.
• With an ...
The work presented in this report of Magister concerns the measure of the ambient
electromagnetic energy to recycle her (it) to feed for example sensors. The antenna allows the
removal of this energy must cover surrounding ...
The mobility of people and cars involved as both cause and consequence in the socioeconomic growth on the one hand and the other urban concentration in major cities, the means of motor transport gradually seized the urban ...
