Ce cours est un cours d’introduction à la réalisation des fonctions linéaires et non-linéaires de base à l’aide de l’amplificateur opérationnel.

Les étudiants appliquent la théorie des circuits, la réaction négative et positive aux amplificateurs opérationnels pour réaliser les fonctions électroniques élémentaires (amplification, filtrage, transposition, addition, soustraction, génération des fonctions périodiques, etc.). Les explications sont illustrées par des exercices au laboratoires avec des démonstrations qui peuvent être reproduite par les élèves par simulation.

Ce cours est un cours d’introduction à la réalisation des fonctions linéaires à l’aide de transistors.

Les étudiants appliquent la théorie des circuits, Ils apprennent à manipuler les modèles petits et grands signaux du transistor bipolaire  afin de réaliser les fonctions d’amplifications et filtrage. Les explications sont illustrées par des exercices avec des démonstrations de circuits simulés à l’aide d’un simulateur de type Spice qui peuvent être reproduite par les élèves.

Ce cours définit les notions de base des circuits électriques composés des trois éléments passifs (résistance, inductance et condensateur), linéaires et des sources de tension et de courant.

On traite ces circuits avec les lois élémentaires de l'électricité puis on développe une série de méthodes de combinaisons des éléments et de transformations du circuit qui mènent à leur simplification et permettent une analyse aisée des courants, tensions et puissances présents. Quelques circuits particuliers classiques sont présentés. 

Toutes ces méthodes sont premièrement développées en régime continu puis elles sont généralisées au régime alternatif, faisant intervenir le calcul complexe. L'importance du régime alternatif réside dans le fait qu'il est omniprésent au niveau de la distribution électrique domestique et industrielle.

This course is presented in French.

Ce cours traite des systèmes alternatifs triphasés, piliers de l'alimentation électrique industrielle et de certains types de machines électriques. Les charges triphasées associées, symétriques ou dissymétriques, seront étudiées ainsi que les puissances actives, réactives et apparentes qui en découlent. Des méthodes de compensation de la puissance réactive seront développées.

Ce cours traite également des régimes transitoires, induits par les enclenchements, déclenchements ou pannes de circuits sur leur source, qu'elle soit continue ou alternative. L'importance de l'étude des régimes transitoires réside dans le fait qu'ils sont la base du fonctionnement d'appareils que l'on retrouve dans de nombreuses applications modernes comme la distribution d'énergie, les entraînements électriques, la recharge de batteries, les alimentations à découpage ou encore de l'éclairage.

Elementary Business Statistics is the first level statistics class required for all Business and Economics majors and can be used to satisfy the statistics requirement in other departments if you are enrolled as a for-credit OU-student. It is designed as an introductory course to statistics theory and methodology. The foundation of statistical inference is first developed through coverage of descriptive statistics and then close coverage of probability theory and probability density functions: specifically the binomial, Poisson, geometric, and normal distributions. The leap from probability theory to actual inferential statistics by way of the Central Limit Theory is accomplished with the use of a gaming model in which students actively participate to solve a constrained goals a constrained goal that requires an understanding of the link between the Central Limit Theorem and the sample size. Confidence internals and Hypothesis testing follow with careful development of both the theory and philosophy of the hypothesis test. Specific hypotheses are covered including test for means, proportions, differences in mean and differences in proportions, and for variances. Finally correlations and regression are covered in detail. The foundation OLS model is developed and students will be able to propose and test various hypotheses concerning a causal relationship assumed to be linear. For credit Oklahoma University students will have the opportunity to interact with face2face teaching assistants once per week in regularly scheduled lab classes.

Le but de ce cours de base en géomatique est de présenter un aperçu des méthodes d'acquisition, de modélisation et de représentation des données à référence spatiale. Les ingénieurs civils et en environnement devront comprendre le rôle et les enjeux de la géomatique face aux disciplines de la construction, de l'aménagement et de l'environnement.

This is an advanced course on modeling, design, integration and best practices for use of machine elements such as bearings, springs, gears, cams and mechanisms. Modeling and analysis of these elements is based upon extensive application of physics, mathematics and core mechanical engineering principles (solid mechanics, fluid mechanics, manufacturing, estimation, computer simulation, etc.). These principles are reinforced via (1) hands-on laboratory experiences wherein students conduct experiments and disassemble machines and (2) a substantial design project wherein students model, design, fabricate and characterize a mechanical system that is relevant to a real world application. Students master the materials via problems sets that are directly related to, and coordinated with, the deliverables of their project. Student assessment is based upon mastery of the course materials and the student's ability to synthesize, model and fabricate a mechanical device subject to engineering constraints (e.g. cost and time/schedule).

6 Virtues to Help Navigate and Illuminate Your Way

Ao longo da história do pensamento, diversos filósofos, teístas ou não, detiveram-se diante

In the 21st century, embedded systems are the systems of future with cellular phones, smart-phones, tablets becoming the dominant platforms for computing and communication. The ubiquity of information and the associated need for the computation that accompanies it is driving this revolution only to be accelerated by the new paradigms such as the Internet-of-Things (IoT). These platforms are clearly very different in terms of their processing requirements which are very unique: real-time needs, high performance but at low energy, compact-code and data segments, and most importantly ever changing software stack. Such unique requirements have led to a complete redesign and reinvention of the both hardware and the software stack from ground up, for example, brand new processors such as ARM, DSPs, network processors were invented all the way up to new virtual machines such as Dalvik, new operating systems such as Android and new programming models and compiler optimizations.

Learn how electronic gadgets are designed, developed, and built as embedded systems that shape the world.

This is part one of a two part sequence. Together these are hands-on, learn-by-doing courses that show you how to build solutions to real-world problems using embedded systems. In this course, we take a bottom-up approach to problem solving, building gradually from simple interfacing of switches and LEDs to complex concepts like a microcontroller-based pacemaker, digital lock, and a traffic light controller. We will present both general principles and practical tips for building circuits and programming the microcontroller in the C programming language. You will develop debugging skills using oscilloscopes, logic analyzers, and software instrumentation. Laboratory assignments are first performed in simulation, and then you will build and debug your system on the real microcontroller. At the conclusion of this part 1 you will possess the knowledge to build your own traffic light controller from the ground up.

This is the fourth time we have offered this course. Since the reviews have been overwhelmingly positive we do not plan major changes over the previous offerings of the course. We did however break the large class into two smaller classes. There are eight labs in part 1 and six labs in part 2. Students can pick and choose a subset of labs to achieve certification. The three labs that students found most rewarding in this part were designing the software algorithm for a demand pacemaker, interfacing switches and LEDS, and the finite state machine traffic light controller.

To complete this course, you will be required to purchase a Texas Instruments TM4C123 microcontroller kit and a few electronic components.

This microcontroller has a state-of-the-art ARM Cortex-M4 processor.

We will provide instructions about purchasing the kit and installing required software at: http://edx-org-utaustinx.s3.amazonaws.com/UT601x/index.html.
