The following thesis consists of a deep research about using renewable energy resources for hydrogen production under Algerian climate on one side, and in different climatic conditions on the other side. The obtained results ...
Traffic accidents caused by a driver falling asleep at the wheel are particularly serious and often fatal, as drowsiness/fatigue seriously impairs the driver's performance, in particular his decision-making ability. ...
Corona discharge is widely used not only to modify the physical characteristics of dielectric materials surfaces, but also as a charging technique for the granular mixtures in view of their electrostatic separation. ...
The demand for electricity has recently increased due to urbanization and the industrial revolution. In the beginning, electricity demand was mainly fulfilled by fossil fuel-based electricity generation, which today poses ...
Today, in a dynamic and competitive environment, establishing a maintenance strategy to significantly track and improve the performance measures of systems become a strategic necessity for most industries. As a static ...
RADAR (Radio Detection and Ranging) is a detection system that uses radio waves to determine the distance (ranging) angle or velocity of objects. Two tasks are very important in radar system; Parameters Estimation and ...
To develop methodologies to improve the quality of repairs, which leads to durable repair, it is necessary all components of repaired system must be considered. The choice of repair material must be compatible with the ...
The aim of this thesis, being the electrothermal modeling and analysis of the self-heating ""Self Heating"" of a HBT SiGe realized in BiCMOS9MW0.13µm technology. The architecture used for the design of the BiCMOS9MW bipolar ...

This thesis work is part of a study of a heterojunction bipolaire phototransistor (HPT) NPN
InP/InGaAs. The phototransistor is modelled using a numerical method, and the results are presented and
discussed. This model ...
This thesis deals with the non-linear analysis of the behaviour of beams, reinforced with composite materials, with respect to shear forces. The modelling is carried out using the general purpose finite element program ...
The main objective of this thesis is to study three-dimensional thermoconvective transfers in impact and channel jets using single and hybrid nanofluids (binary and ternary hybrid nanofluids) of different types and shapes. ...
Recently the influence of the huge increase in energy cost has had an impact on the
Manufacturing or transformation process where drying is implemented. Herbal and
medicinal plants dehydration is among these ...
A communication system based on WDM wavelength division multiplexing technology is a
better approach to achieve the optimal utilization of fiber capacity in order to increase the
number of communication channels, research ...
Wireless capsule endoscopic (WCE) is a non-invasive device, introduced in 2000, that is used
by physicians in the diagnosis of diseases of the gastrointestinal (GI) tract. Despite these limited
resources, one capsule can ...
This thesis presents a photovoltaic system connected to the grid via an active filter based on a
three-phase three-level inverter. With this configuration, three advantages can be obtained,
namely the elimination of the ...
This work presents a two-dimensional numerical study of the phenomena of mixed
laminar and turbulent convection in a ventilated square cavity. The geometry considered
consists of three blocks dissipating heat by Joule ...
In this work, an experimental study and analysis of the effects of environmental relative
humidity (RH %) on the transport mechanisms of electrical charges in PI films have been
presented. The evolution of the surface ...
This thesis's work contributes to the numerical study of mixed convection and entropy
generation in two different configurations filled with simple and hybrid nanofluids. Two
computational codes (Ansys-Fluent 18 and ...
The major challenge in the new emerging technologies like IoT and 5G is the obtention of available and enough spectrum resources for their transmissions. Hence, it becomes necessary to optimize the actual spectrum utilization ...
The MIMO (Multiple Input/Multiple Output) concept has been very successful in telecommunications. It is based on the use of several antennas for transmission and
several antennas for reception, which enabled the ...
