1. Synthesis of Safety-Critical Real-Time Systems
Sammanfattning : Modern safety-critical real-time systems are becoming more and more complex, due to sophisticated applications such as advanced driving assistance, automated driving, advanced infotainment, and applications involving machine learning and deep learning. This has led to increased requirements for the communication infrastructures. LÄS MER
2. Discrete element technique for modeling high-speed railway tracks
Sammanfattning : The Discrete element method (DEM) is a methodology to investigatethe interactions among granular materials. It analyzes the behavior of par-ticulate environments by solving force-displacement equations that adhereto Newton’s second law of motion. LÄS MER
3. A study of the track degradation process related to changes in railway traffic
Sammanfattning : This licentiate thesis presents the results of a research project concerning railroad maintenance. After acquiring the state-of-the-art knowledge in relevant areas a prediction model for railroad track degradation has been developed. The model is named DeCoTrack (Degradation Cost Of Track).
