1. 1. Tailoring Gaussian processes and large-scale optimisation

   Författare :Carl Jidling; Thomas B. Schön; Niklas Wahlström; Adrian Wills; Lars Kai Hansen; Uppsala universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Gaussian processes; Tomographic reconstruction; Large-scale optimisation; Electrical Engineering with specialization in Signal Processing; Elektroteknik med inriktning mot signalbehandling;

   Sammanfattning : This thesis is centred around Gaussian processes and large-scale optimisation, where the main contributions are presented in the included papers.Provided access to linear constraints (e.g. equilibrium conditions), we propose a constructive procedure to design the covariance function in a Gaussian process.

3. 2. Optimisation methods for solving a large-scale avionics scheduling problem

   Författare :Emil Karlsson; Elina Rönnberg; Kaj Holmberg; Simin Nadjm-Tehrani; Musliu Nysret; Linköpings universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Optimisation; Decomposition; Large-scale scheduling; Avionics scheduling;

   Sammanfattning : Modern computer systems in aircraft are based on an integrated modular avionic architecture. In this architecture, software applications share hardware resources on a common avionic platform. Many functions in an aircraft are controlled by software and a failure in such software can have severe consequences. LÄS MER

4. 3. Modelling the Role of Nuclear Power and Variable Renewables in Climate Change Mitigation

   Författare :Mariliis Lehtveer; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; energy system model; nuclear power; multi-criteria analysis; variable renewables; climate change; optimisation;

   Sammanfattning : As the number of people on Earth and our energy needs have increased the system for providing this energy has become ever more complex and complicated and thus the need for more systematic understanding of it has grown. However, change in energy system is slow and many of the challenges that we face such as mitigating climate change need global solutions. LÄS MER

5. 4. Scalable and Reliable Data Stream Processing

   Författare :Paris Carbone; Seif Haridi; Peter Pietzuch; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; distributed systems; stream processing; data management; databases; distributed computing; data processing; fault tolerance; database optimisation; programming systems; data science; data analytics; computer science; Informations- och kommunikationsteknik; Information and Communication Technology;

   Sammanfattning : Data-stream management systems have for long been considered as a promising architecture for fast data management. The stream processing paradigm poses an attractive means of declaring persistent application logic coupled with state over evolving data. LÄS MER

7. 5. Resource, Data and Application Management for Cloud Federations and Multi-Clouds

   Författare :Vamis Xhagjika; Leandro Navarro Moldes; Vladimir Vlassov; Gregory Chockler; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Multi-Cloud; Geo-Distribution; Live Streaming; Locality optimisation; Multicast; Multi-Cloud Overlay; Cloud Federation; Web Real-time Communications; WebRTC-RTCWEB; Media Quality; Computer Science; Datalogi;

   Sammanfattning : Distributed Real-Time Media Processing refers to classes of highly distributed, delay no-tolerant applications that account for the majority of the data traffic generated in the world today. Real-Time audio/video conferencing and live content streaming are of particular research interests as technology forecasts predict video traffic surpassing every other type of data traffic in the world in the near future.
