    Method for Indexing and Identifying Multimedia Documents
    (European Patent Office, 2005-06-16) Essafi Hassane; Guezouli Larbi; Sayah Salima; Behloul Ali; Mandridake Clarisse; Essafi Louafi
    The method for indexing multimedia documents comprises the following steps: (a) identification and extraction, for each document, of terms ti comprising vectors characterizing the properties of the document; (b) storage of terms ti in a term base comprising P terms; (c) determination of a maximum number N of desired concepts including the most relevant terms ti; (d) calculation of the matrix T of distances between the terms ti of the term base, (e) decomposition of the set P of terms ti of the term base into N parts Pj (1=j=N) such that P = P1 UP2 UPj UPN, each part Pj comprising a set of terms tij and being represented by a concept cj, terms ti being divided in such a manner that the furthermost terms are located in distinct parts Pl, Pm and the nearest terms are located in the same part Pl; (f) structuring of the dictionary of concepts and (g) construction of a prints base consisting of the set of concepts ci representing the terms ti of said documents, each document being associated with a print which is proper thereto.

    Introduction au Calcul Formel: Maple & CAML
    (Éditions Universitaires Européennes, 2016-01-01) Guezouli Larbi
    Le calcul formel est un type de calcul qui permet de manipuler les grands nombres dans des calculs intensifs en utilisant des algorithmes optimisés dans le but de minimiser le temps de calcul. Appelé aussi calcul symbolique, pour compléter les méthodes de calcul numérique. Les logiciels de calcul formel ont beaucoup évolué au cours de ces dernières années. Ils sont destinés aux mathématiciens, aux informaticiens et aux utilisateurs qui utilisent les mathématiques comme les électroniciens, les mécaniciens, ... Ce document est destiné aux étudiants de la première année Licence tronc commun Math-Informatique. Il décrit un cours de 20 heures avec 20 heures de travaux pratiques. Les points traités dans ce cours sont indispensables pour pouvoir utiliser un logiciel de calcul formel. Les logiciels étudiés dans ce cours sont Maple et Caml.

    Enhancing Transparency in Batna's Public Transportation: A Cost-Effective Real-Time Bus Tracking and Route Optimization System
    (Jomard Publishing, 2025-01-01) Alloui Zineb Nedjla; Bourebbou Fetima; Guezouli Larbi
    Public transportation in Batna suffers from a lack of transparency, leading to inefficiencies, unreliable schedules, and a poor commute experience. This thesis presents a comprehensive and cost-effective bus tracking system that aims to modernize public transportation in the city. The proposed solution integrates a GPS-enabled Raspberry Pi device for real-time location tracking, an AI-powered backend that uses long-short-term memory (LSTM) networks for accurate estimated arrival time (ETA) predictions, and a mobile Android application for user interaction. The system also incorporates Dijkstra’s algorithm to offer optimized route planning. The emphasis was placed on low-cost hardware, lightweight web frameworks such as Flask, and secure communication via HTTPS and DDNS. The developed platform was tested and validated through real-world simulations, demonstrating significant improvements in route accuracy, ETA reliability. This work offers a modular and scalable foundation for improving public transportation in resource-constrained urban environments.
