Have you ever wondered how information is transmitted using your mobile phone or a WiFi hotspot? This introductory course seeks to enable you to understand the basic engineering tools used and tradeoffs encountered in the design of these communication systems.  
 
This course is divided into three parts. In Part 1, we examine the point-to-point link, which communicates information from a single transmitter to a single receiver. Part 2 examines how multiple transmitters can share the same physical channel. Part 3 discusses how information can be transmitted reliably from one station to another over a network that connects multiple stations. Online interactive exercises are included to help build your intuition.

This course was inspired by and built upon the course 6.02 Digital Communication Systems developed at MIT, which Prof Bertram Shi worked on during his sabbatical in 2009.

Our lives are full of combinations. Combinatorial mathematics is just the science to deal with combinations of discrete items. As an ancient field, the history of combinatorial mathematics can be traced back over 4000 years to the age of the Great Yu in ancient China. Today, combinatorial mathematics is regarded as the basis of computer science since the algorithms in programming heavily rely on the analysis of the discrete elements.

Instead of relying on the traditional mathematical "theorem - proof" format, this course demonstrates various principles in an intuitive manner with ancient stories, the scenes of movies and even a magic show. What you’ll learn:

  • The counting principles based on the basic operations “+”, “-”, “*”, “/”; 
  • Generating functions
  • Recurrent number serials such as Fibonacci number, Catalan number, and more
  • Pigeon hole principles
  • Inclusion and exclusion principles
  • Polya counting based on group theory

This course is based on a highly regarded on-campus Tsinghua class called Combinatorics, and is ideal for students who are interested in mathematics or computer science. Enroll today and learn the mathematical theory needed to solve the real-world problems!

As a data pro, you know that some scenarios—particularly those involving real-time analytics, site personalization, IoT, and mobile apps—are better addressed with NoSQL storage and compute solutions than they are with relational databases. Microsoft Azure has several NoSQL (or “Not Only SQL”) non-relational data storage options to choose from. NoSQL databases are generally built to be distributed and partitioned across many servers. And they’re built to scale out for high availability and to be flexible enough to handle semi-structured and unstructured data. If you have a data model that is constantly evolving and you want to move fast, that’s what these databases are about.

In this practical course, complete with labs, assessments, and a final exam, join the experts to learn how NoSQL has evolved over time. Explore non-relational data storage options in Azure, and see how to use them in your applications. Find out how to create, store, manage, and access data in these different storage options. Get an in-depth look at Azure Table Storage, DocumentDB, MongoDB, and more. Learn about the “three Vs”—variety (schemas or scenarios that evolve quickly), volume (scale in terms of data storage), and velocity (throughput needs to support a large user base). Take this opportunity to get hands-on with NoSQL options in Azure.

Smartphones, tablettes, ces appareils ultra-portables sont désormais omniprésents dans notre vie quotidienne. Il y a des applications pour presque tout : retoucher ses photos, réserver une place de cinéma, réviser le code de la route, choisir une recette de cuisine, tourner et monter des clips vidéos, ou trouver les restaurants les plus proches.

Derrière ces applications il y a un savoir-faire spécifique à la programmation sur plateformes mobiles. En effet, contrairement aux ordinateurs classiques, les contraintes imposées par les caractéristiques ces terminaux font que certains « gestes simples » pour l'utilisateur, comme faire dérouler une liste de données, impliquent en réalité des mécanismes plus complexes.

Ce MOOC est le premier d'une série de deux MOOCs consacrés à la programmation sur iPhone et iPad. Il se concentre sur le développement d'applications « mono-vues » et présente en détail les principes d'une interaction réussie de vos applications avec ses utilisateurs. Nous avons également décidé de prendre en compte les dernières nouveautés introduites dans iOS. Ainsi, ce MOOC, s'il évoque Objective-C, le langage « historique » de développement sur cette plateforme qu'il faut connaître, passera beaucoup de temps sur le nouveau langage Swift (dans sa version 3, annoncée en Septembre 2016 avec iOS10). Un parallèle avec la problématique du développement de systèmes embarqués est également fait.

L'objectif, si vous suivez attentivement ce cours et réalisez les exercices proposés, est de vous rendre autonomes dans la réalisation d'applications pour l'écosystème iOS (le dernier exercice est d'ailleurs un jeu d'adresse). Vous serez aussi capables de travailler non seulement dans l'environnement de  développement d'Apple mais aussi dans des environnements similaires. Les exercices sont réalisés sous iOS10, publié en septembre 2016. Nous recommandons donc l'usage de Xcode 8 ou ultérieur (accès gratuit sur le site d'Apple).

Ce cours est principalement destiné à des personnes maîtrisant déjà la programmation objet. Il est dérivé d'une unité d'enseignement de 5eme année (master 2) dispensée à l'Université Pierre et Marie Curie, le premier établissement universitaire à avoir proposé en France, en 1967, un diplôme d'informatique. Il tient également compte des nombreux retours des MOOCs qui se sont déroulés en 2014 et en 2015.

Si ce sujet vous intéresse, n'hésitez pas à vous inscrire et à venir nous suivre. J'ai reçu plusieurs témoignages d'anciens participants en 2014 et 2015 qui se sont réorientés vers la programmation mobile après avoir participé à l'une des éditions précédentes.
