6. Security of Time Synchronization for PMU-based Power System State Estimation: Vulnerabilities and Countermeasures
Sammanfattning : Phasor Measurement Units (PMUs) constitute an emerging technology that is essential for various smart grid applications such as phase angle monitoring, power oscillation damping, fault localization, and linear state estimation. To obtain precise PMU measurements of voltage and current phasors, time synchronization in the order of 1 microsecond is typically required. LÄS MER
7. Distributed Monitoring and Resource Management for Large Cloud Environments
Sammanfattning : Over the last decade, the number, size and complexity of large-scale networked systems has been growing fast, and this trend is expected to accelerate. The best known example of a large-scale networked system is probably the Internet, while large datacenters for cloud services are the most recent ones. LÄS MER
8. Improving the Adaptability of the End-host : Service-aware Network Stack Tuning
Sammanfattning : The Internet of today is very different from how it used to be. Modern networked applications are becoming increasingly diverse. Consequently, a variety of requirements must be met by the network. Efforts to make the underlying mechanisms of the Internet more flexible have therefore been made to adapt to this diversification.

9. A Bottom-Up Approach to Real-Time Search in Large Networks and Clouds
Sammanfattning : Networked systems, such as telecom networks and cloud infrastructures, generate and hold vast amounts of conguration and operational data. The goal of this work is to make all this data available through a real-time search process named network search , which will enable new real-time management solutions. LÄS MER
10. Efficient synchronization and coherence for nonuniform communication architectures
Sammanfattning : Nonuniformity is a common characteristic of contemporary computer systems, mainly because of physical distances in computer designs. In large multiprocessors, the access to shared memory is often nonuniform, and may vary as much as ten times for some nonuniform memory access (NUMA) architectures, depending on if the memory is close to the requesting processor or not.
