11. Verification and Scheduling Techniques for Real-Time Embedded Systems
Sammanfattning : Embedded computer systems have become ubiquitous. They are used in a wide spectrum of applications, ranging from household appliances and mobile devices to vehicle controllers and medical equipment. LÄS MER
12. Real-Time Communication over Switched Ethernet with Resource Reservation
Sammanfattning : Due to the need for advanced computer-controlled functionality in distributed embedded systems the requirements on network communication are becoming overly intricate. This dissertation targets the requirements that are concerned with real-time guarantees, run-time adaptation, resource utilization and flexibility during the development. LÄS MER
13. Preemption-Delay Aware Schedulability Analysis of Real-Time Systems
Sammanfattning : Schedulability analysis of real-time systems under preemptive scheduling may often lead to false-negative results, deeming a schedulable taskset being unschedulable. This is the case due to the inherent over-approximation of many time-related parameters such as task execution time, system delays, etc. LÄS MER
14. Towards Fully Dynamic Surface Illumination in Real-Time Rendering using Acceleration Data Structures
Sammanfattning : The improvements in GPU hardware, including hardware-accelerated ray tracing, and the push for fully dynamic realistic-looking video games, has been driving more research in the use of ray tracing in real-time applications. The work described in this thesis covers multiple aspects such as optimisations, adapting existing offline methods to real-time constraints, and adding effects which were hard to simulate without the new hardware, all working towards a fully dynamic surface illumination rendering in real-time.

15. Performance Aspects of Databases and Virtualized Real-time Applications
Sammanfattning : Context: High computing system performance depends on the interaction between software and hardware layers in modern computer systems. Two strong trends that effect different layers in computer systems are that single processors are now more or less completely replaced by multiprocessors, which are often organized into clusters, and virtualization of resources.
