The objective of this work is to study discrete dynamical systems, introducing fundamental concepts such as stability, bifurcation, and chaos. We will then apply these concepts to a
discrete-time predator-prey system with ...
This work provides insight into the application of the Galerkin method for solving
two boundary value problems. The first problem deals with bidimensional linear
Schrödinger parabolic partial differential equations, and ...
The present work is basically devoted to study the existence and uniqueness of solutions
for certain classes of nonlinear fractional differential equations with initial conditions via
the ψ−Caputo fractional derivative ...
Statistical distributions are widely applied to describe di§erent real world phenomena. As a result of the usefulness of statistical distributions, many researchers have
studied their theory extensively and new distributions ...

This work presents a program for calculating the Value at Risk (VaR) using the
Extreme Value Theory (EVT), a statistical theory that focuses on studying rare
cases. EVT has numerous applications, and in this study, we ...
This thesis investigates hydrodynamic and thermal instabilities in a Taylor-Couette system subjected to differential heating, analyzing the influence of geometric parameters and rotational conditions of the cylinders across ...
1,10-phenanthroline and its derivatives are widely used in chemistry and biology, these molecules are useful in a range of biological (anti-Alzheimer, antifungal, anticancer,...) and chemical processes. Tin (IV) complexes ...

The city of El Khroub faces major challenges in urban organization and management due to its rapid urban growth and strong functional attractiveness, since it began accommodating the population overflow mainly from Constantine ...
The present study focused on the two-dimensional numerical study of the effect of
dimensionless parameters on the transition from mixed convection (laminar and turbulent) within a cavity with an aspect ratio A. The right ...
Stainless steels are widely used in industries such as aerospace, biomedical and
automotive due to their corrosion resistance and excellent mechanical properties. However,
their machinability remains a major challenge, ...
Les applications pratiques du principe de l'autonomie de la clause compromissoire ont montré son importance pour l'ensemble du système arbitral, depuis son apparition dans la justice néerlandaise et allemande, puis sa ...
Introduction: schizophrenia is a complex psychiatric disorder with an etiology involving
both environmental and genetic factors. Dopaminergic pathways, in particular, play a key
role in its pathophysiology. Several ...
Introduction: Hypospadias, a complex urogenital malformation, raises significant
concerns in pediatric urology due to its varied clinical implications. This thesis focused on
a comprehensive approach, including an ...
This study focused on the synthesis of new hybrid materials composed of tin hexachloride
and ligand matrices. The structural analysis and physico-chemical characterisation of these
compounds were carried out using ...

التعقب النحوي نشاط قديم قدم النحو نفسه، وهو نشاط كان له الفضل الكبير في تطور علم النحو، وازدهاره، وقد حاولنا في هذه الصفحات أن نبرز أهمية هذا النشاط، وأن نقف على مظاهره وأسبابه، ثم أتبعنا ذلك بدراسة تطبيقية على كتاب "المساعد ...
The thesis delves into the Watergate scandal, a turning point in the American history, and its perennial reverberations that drastically altered the U.S. political framework. The study examines the significance of the ...
The sol- gel method is a very attractive technique for elaborating materials, since it is known to be able to synthesize, at low temperature, bothnanometric powders ormaterials with finemicrostructure. Moreover,it ensuresa ...
