16. Modelling and Lagrangian control of mixed traffic: platoon coordination, congestion dissipation and state reconstruction
Sammanfattning : Traffic congestion is a constantly growing problem, with a wide array of negative effects on the society, from wasted time and productivity to elevated air pollution and reduction of safety. The introduction of connected, autonomous vehicles enables a new, Lagrangian paradigm for sensing andcontrolling the traffic, by directly using connected vehicles inside the traffic flow, as opposed to the classical, Eulerian paradigm, which relies on stationary equipment on the road.

17. Offline and Online Models for Learning Pairwise Relations in Data
Sammanfattning : Pairwise relations between data points are essential for numerous machine learning algorithms. Many representation learning methods consider pairwise relations to identify the latent features and patterns in the data. This thesis, investigates learning of pairwise relations from two different perspectives: offline learning and online learning. LÄS MER
18. Improving Performance and Quality-of-Service through the Task-Parallel Model : Optimizations and Future Directions for OpenMP
Sammanfattning : With the failure of Dennard's scaling, which stated that shrinking transistors will be more power-efficient, computer hardware has today become very divergent. Initially the change only concerned the number of processor on a chip (multicores), but has today further escalated into complex heterogeneous system with non-intuitive properties -- properties that can improve performance and power consumption but also strain the programmer expected to develop on them.

19. Understanding Task Parallelism : Providing insight into scheduling, memory, and performance for CPUs and Graphics
Sammanfattning : Maximizing the performance of computer systems while making them more energy efficient is vital for future developments in engineering, medicine, entertainment, etc. However, the increasing complexity of software, hardware, and their interactions makes this task difficult. LÄS MER
20. Tools for Understanding, Debugging, and Simulation Performance Improvement of Equation-based Models
Sammanfattning : Equation-based object-oriented (EOO) modelling languages provide a convenient, declarative method for describing models of cyber-physical systems.Because of the ease of use of EOO languages, large and complex models can be built with limited effort. LÄS MER
