Authors: Ramdani, Dounya; Saha, Louiza Mallek
Abstract: Dans un contexte de transformation numérique du secteur logistique, ce
mémoire présente le développement de CONTRACK : une plateforme web
dédiée à la réservation,au suivi des conteneurs maritimes et à la prédiction des
opérations portuaires. L’objectif est de répondre aux limites des systèmes
traditionnels encore majoritairement manuels en Algérie. En s’appuyant sur
des technologies modernes (React, Django REST, XGBoost), cette solution
permet aux utilisateurs de réserver des conteneurs, de suivre leur statut
opérationnel et d’anticiper les délais logistiques grâce à un module de
machine learning entraîné sur plus de 10 000 historiques d’expéditions.
L’approche proposée vise à fluidifier les échanges entre clients et compagnies
maritimes, tout en améliorant la transparence, l’efficacité et la traçabilité

Authors: SAHNOUN, Belkacem; BOUDIAR, Toufik (Directeur de thèse)
Abstract: This work focuses on the need for smaller non-reciprocal components in modern
communication systems. A new coplanar waveguide (CPW) isolator design is proposed,
which includes a High-Impedance Wire (HIW) structure in the ground plane. Using full-wave
simulations, it is shown that the operating frequency of a fixed HIW-CPW design can be
adjusted by choosing the appropriate ferrite material: Yttrium Iron Garnet (YIG) operates in
the K-band, while Barium Hexaferrite (BaM) operates in the U-band. Adding an alumina layer
further improves performance. A compact 9-slot design with alumina achieved very high
non-reciprocity (36.4 dB ENR) with low insertion loss (0.4 dB). This study demonstrates a
flexible approach to realizing compact, high-performance isolators that can be tuned to
different frequency bands through material selection and structural design

Authors: AKHZEROUN, Aimen; BOUCHACHI, Islem (Directeur de thèse)
Abstract: This thesis has known the proposition of a microwave device that is a voltage controlled oscillator for L-band
applications, the document included four chapters in which we have discussed various microwave VCO technologies, their principle of operation, simulation and its results, and finally the realization of the device using microstrip transmission lines and Surface Mounted Device SMD components, a discussion took place to compare simulation to measurement results. The proposed VCO operates from 1GHz up to 1:65GHz, that is a band with high immunity to atmospheric attenuation which makes it suitable for Long range radar systems

Abstract: Security Information and Event Management (SIEM) systems are critical for modern cybersecurity, but their
reliance on static rule-based detection limits their effectiveness against evolving threats. This thesis presents
a Hybrid AI-SIEM Framework that combines the strengths of machine learning models and the open-source
Wazuh SIEM to improve attack identification and response. We integrate a CNN-LSTM architecture for
detecting complex attacks like DDoS and anomalies, and augmentWazuh with targeted solutions for various
threats, including malware detection using YARA, LLMs technology,Wazuh rules, and Suricata-based network
intrusion detection. The framework was tested against several critical attack types, including DDoS,
brute-force login attempts, web application exploits, malware infections, and suspicious activities. The
result is a layered, adaptable system that not only detects but actively responds to security incidents with
improved accuracy and reduced false positives. This research demonstrates how hybrid intelligence can
transform static SIEMs into smarter, more responsive security ecosystems
