Title: Cours Mathématiques 3 Authors: Slimani, Bachir Abstract: Ce polycopié de cours de Mathématiques 3 est conçu comme un support pédagogique destiné aux étudiants de la deuxième année Licence des filières technologiques (Génie Mécanique, Génie Électrique, Génie Civil et Génie Procédés). Son objectif principal est de fournir les outils mathématiques fondamentaux nécessaires à la modélisation et à la résolution de problèmes physiques et techniques rencontrés dans les modules de spécialité. Le contenu de cet ouvrage est structuré de manière progressive pour faciliter l’apprentissage et la maîtrise des concepts : 1. L’intégration (simple et multiple) : Elle constitue la base du calcul des surfaces, des volumes, des centres de gravité et des moments d’inertie, éléments cruciaux pour le génie civil et la mécanique. 2. Les intégrales généralisées : Elles permettent d’aborder des phénomènes s’étendant à l’infini ou présentant des singularités. 3. Les équations différentielles : Elles représentent le langage universel pour décrire l’évolution des systèmes (vibrations mécaniques, circuits électriques, cinétique chimique). 4. Les séries (numériques, entières et de Fourier) : Ces outils sont indispensables pour l’approximation des fonctions et l’analyse fréquentielle des signaux. 5. Les transformations de Fourier et de Laplace : Véritables piliers de l’automatique et du traitement du signal, ces transformations permettent de passer du domaine temporel au domaine fréquentiel pour simplifier la résolution des systèmes différentiels complexes. Chaque chapitre présente des définitions rigoureuses, des théorèmes fondamentaux et des exemples d’application détaillés pour illustrer la théorie par la pratique.

Title: Fundamental Electronics 01 Authors: Chabachi, Salem Abstract: Foreword This course is designed to provide second-year undergraduate students in the field of Science and Technology, specialty Electronics / Electrotechnics / Automatics, with the fundamental knowledge and theoretical as well as practical concepts necessary to understand the basic principles of electronics and their various applications. It follows the official syllabus for the module "Fundamental Electronics 1". This course, titled Fundamental Electronics 1, enables students to perform calculations, analyze, and interpret electronic circuits. It also helps them understand the properties, electrical models, and characteristics of electronic components such as diodes, bipolar transistors, and operational amplifiers. The course is divided into five chapters: 1. The first chapter presents general concepts related to the application of Ohm‘s and Kirchhoff‘s laws, as well as methods for analyzing DC circuits (including the theorems of Norton, Thévenin, Superposition, Kennelly, Millman, and Maximum Power Transfer). 2. The second chapter covers passive two-port networks (quadripoles) in detail. Topics include: matrix representations of two-port networks, combinations of quadripoles, relationships between parameters, and the quantities characterizing a quadripole's behavior in a circuit, such as input and output impedance, and current and voltage gain. This chapter also includes frequency analysis of RC, CR, and RLC filters (transfer functions and Bode plots), to highlight the frequency-filtering properties of these electrical circuits. 3. The third chapter provides a review of semiconductors as an introduction to PN junctions and junction diodes. It also studies circuits based on diodes, such as half-wave and full-wave rectifiers, along with different types of diodes (Zener diode, Schottky diode, Varicap diode, light-emitting diodes, and photodiodes). 4. The fourth chapter is dedicated to the static and dynamic operation of bipolar junction transistors (BJTs), including various configurations such as common-emitter, common-base, and common-collector setups, as well as multi-stage amplifiers. 5. The final chapter addresses the operation of one of the most widely used and popular integrated circuits: the operational amplifier. It covers different types of configurations, particularly linear applications such as adders, subtractors, integrators, and differentiators Description: Intended for 2nd-Year Undergraduate Students Field: Science and Technology (ST) Specialty: Electronics / Electrotechnics / Automatics (L2 – S3)

Title: Course Handout Fire Safety Authors: SMILI, Billel Abstract: This handout, a crucial academic resource, is specifically designed for third-year LMD students specializing in Industrial Hygiene and Safety at Ahmed Draia University of Adrar. Its purpose is to make the learning of fundamental fire safety concepts both accessible and engaging by clearly presenting the key principles. This document provides a concise summary of national and international regulatory requirements while offering a comprehensive overview of fire safety engineering, including both passive and active fire protection systems. It supports the primary objective of fire safety legislation, which is to ensure the protection of people, particularly workers, within and around buildings in the event of a fire. In addition, it aims to safeguard workers’ health, ensure business continuity, and protect property, including both building structures and their contents.. Finally, this handout emphasizes the importance of occupational safety and environmental protection by defining clear objectives, enforcing strict monitoring procedures, and ensuring compliance with standards. It also highlights the role of regular inspection and maintenance of fire detection and safety equipment in preventing fire development, spread, and escalation. This handout serves as a comprehensive course manual entitled "Fire Safety", specifically designed for students in science and engineering fields, particularly those specializing in industrial safety, fire protection, and risk management. It aims to introduce the fundamental principles of fire behavior, industrial hazards, fire detection systems, extinguishing methods, and smoke control techniques. The objective of this lecture notes is to provide students with a clear and structured understanding of fire safety engineering concepts, as well as practical approaches used in industrial and occupational risk prevention.This handout is organized into seven chapters a Description: Level: 3rd YEAR LICENCE (LMD) in HSI Semester: 5th semester (S5)
