Have you ever wondered what it takes to get your train on the right platform at the scheduled time every day?
Understanding the complexity behind today’s sophisticated railway systems will give you a better insight into how this safe and reliable transportation system works. We will show you the many factors which are involved and how multiple people, behind the scenes, have a daily task that enables you to get from home to work. Journey with us into the world of rail - a complex system that connects people, cities and countries.
Railway systems entail much more than a train and a track. They are based on advanced technical and operational solutions, dealing with continuously changing demands for more efficient transport for both passengers and freight every day. Each system consists of many components that must be properly integrated: from trains, tracks, stations, signaling and control systems, through monitoring, maintenance and the impact on cities, landscape and people. This integration is the big challenge and the source of many train delays, inconvenient connections and other issues that impact our society.
This engineering course attempts to tackle those issues by introducing you to a holistic approach to railway systems engineering. You will learn how the system components depend on each other to create a reliable, efficient and state-of-the-art network.
We will address questions such as:
- How do railways work and how did they evolve over time?
- What factors give rise to everyday issues?
- How do different components of the railway system interact?
- What is the effect of train stations and the network from an urban, social and economic point of view?
- What can be done to improve the monitoring and maintenance of tracks?
- How are timetables designed in a way that balances passenger demand with the capacity of the railway and is adaptable to handle unexpected disturbances?
- What can be done to prevent and deal with disturbances caused by external factors and how do they affect the whole rail system?
- How does the design of railways influence their performance over time?
A new serious game has been designed for this course to guide you through the process of decision making while building a rail network and maintaining it. Cities have to be connected in an ever-changing setting, dealing with wear, capacity, developments and disturbances. What choices do you make and how do they affect the performance of the system?
For this MOOC, our very own TU Delft Measurement Train will be used to give you insights of the track and vehicle design, real-life monitoring and pantograph/catenary interaction. Together with the game this will give you the opportunity to see real-life examples and implement the knowledge you learn in a simulated environment.
This first ever MOOC on railway systems engineering is delivered by the renowned experts of TU Delft and leading professionals working in the industry. It combines theoretical knowledge with practical examples, with the main objective to maintain a high degree of reliability under predictable and unknown circumstances.
If you want to learn about the science behind the exciting world of railway systems - whether train, metro or tram - this course will set you on the right track!
In Part 2 of Science and Cooking (Part 1 is available here), we will be visited by more world-famous chefs who use a number of different styles and techniques in their cooking. Each chef will demonstrate how he or she prepares delicious and interesting creations, and we will explore how fundamental scientific principles make them possible.
Topics will include:
- How cooking changes food texture
- Making emulsions and foams
- Phase changes in cooking
You will also have the opportunity to become an experimental scientist in your very own laboratory — your kitchen! By following along with the recipes of the week, taking precise measurements, and making skillful observations, you will learn to think like both a chef and a scientist. This practice will prepare you for the final project, when you will design and perform an experiment to analyze a recipe of your choice from a scientific perspective.
The lab is certainly one of the most unique components of this course — after all, in what other science course can you eat your experiments?
This course focuses on the physical changes that occur during cooking. If you are interested in signing up for “Part 1,” which focuses more on the chemistry of cooking, you can do so here.
Savez-vous que les machines les plus puissantes au monde sont massivement parallèles ? Saviez-vous que les objets les plus courants de notre vie quotidienne, comme les voitures ou les smartphones, sont de véritables ordinateurs parallèles ?
En effet, les voitures les plus simples embarquent une trentaine de capteurs et processeurs sur lesquels s'exécutent différents programmes qui coopèrent. Les véhicules les plus sophistiqués dépassent d'ailleurs la centaine de capteurs et processeurs... et ne parlons pas des véhicules autonomes qui se profilent dans un avenir proche. D'ailleurs, vous savez tous qu'internet peut également être vu comme un système massivement parallèle ?
Bref, les systèmes parallèles ont déjà envahi notre vie quotidienne et sont présents dans tous les secteurs. La principale conséquence est que l'informaticien d'aujourd'hui se doit de maîtriser ce type de programmation, qui est loin d'être trivial. En effet, tôt ou tard, il ne pourra qu'être confronté à ce type de problèmes.
L'objectif du MOOC « Programmation Concurrente » est de vous donner un aperçu de ce domaine. Nous y présenterons les problèmes posés par la concurrence, les solutions algorithmiques proposés (moniteurs, sémaphores, etc.) et illustrerons nos propos à l'aide du langage Java, qui, dans sa version 8 (en fait depuis la version 7), intègre de nombreux mécanismes permettant au programmeur désireux de comprendre la programmation concurrence, de s'y focaliser sans avoir à manipuler des mécanismes de bas niveau, comme ceux que l'on trouve dans de nombreux langages (par exemple, C avec les bibliothèques Posix).
Ce cours est principalement destiné à des personnes maîtrisant déjà au moins un langage de programmation, objet si possible. Il est dérivé d'une unité d'enseignement de troisième année dispensée à l'Université Pierre et Marie Curie, le premier établissement universitaire à avoir proposé en France, en 1967, un diplôme d'informatique.
Afin que vous puissiez mieux suivre ce MOOC, il est nécessaire de connaître le langage Java. À ce titre, des ressources de préparation sont à votre disposition via le lien suivant : http://lip6.fr/Fabrice.Kordon/moocprc2017.php
