Homepage for the seminar "Real-Time Systems" in SS 2016


Real-time systems play a crucial role in many applications, such as avionic control systems, automotive electronics, telecommunications, industrial automation, and robotics. Such safety-critical applications require high reliability in timing assurance to prevent from serious damage to the environment and significant human loss. 

There will be several categoried options, offered by Prof. Chen. You can also select your own options of literatures, under the approval by Prof. Chen
