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 ...
The assessment of the distribution of potential earthquake damage at the urban scale provides
a basis for emergency planning and seismic risk reduction policies. Skikda is located in a
region of moderate seismicity. ...
This thesis represents a biomedical study and research, where we designed and fabricated a device
for the generation of cold atmospheric pressure plasma jet, In addition to implementing this device for
the cleansing of ...
The objective of the work presented in this thesis concerns the study and control of a photovoltaic (PV)
pumping system in alternating mode operating at its maximum power. For this, we carried out a
comparative study ...
This work is part of the study of optimal integration of Distributed Generation
(DG) based on photovoltaic and wind turbine renewable energy sources on the radial
IEEE 33-JB, IEEE 69-JB, and IEEE 118-JB distribution ...
The objective of this thesis is based on two different axes. The first is the study of the cracked
pipe due to internal pressure variation and the other is the benefit of a repair to improve the
life of the pipeline.
First, ...
