  1. 11. Vertical Axis Wind Turbines : Tower Dynamics and Noise

    Författare :Erik Möllerström; Jonny Hylander; Fredric Ottermo; Göran Sidén; Hans Bernhoff; Mats Åbom; Uppsala universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; VAWT; H-rotor; eigenfrequency; semi-guy-wired tower; noise emission; sound power level;

    Sammanfattning : Vertical axis wind turbines (VAWTs) have with time been outrivaled by the today common and economically feasible horizontal axis wind turbines (HAWTs). However, VAWTs have several advantages such as the possibility to put the drive train at ground level, lower noise emissions and better scaling behavior which still make them interesting for research.

  2. 12. Elbow kinematics : studies of the elbow joint under normal conditions and after joint replacement

    Författare :Anne Ericson; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Background: Total elbow arthroplasty (TEA) is used for treatment of patients with severe pain and disability due to reumatoid arthritis. Long term results are not as good as for hip and knee replacements. LÄS MER

  3. 13. Noise, eigenfrequencies and turbulence behavior of a 200 kW H-rotor vertical axis wind turbine

    Författare :Erik Möllerström; Jonny Hylander; Fredric Ottermo; Hans Bernhoff; Göran Sidén; Mats Åbom; Uppsala universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; VAWT; H-rotor; eigenfrequency; semi-guy-wired tower; noise emission; sound power level; microphone array; turbulence intensity; power curve; Engineering Science with specialization in Science of Electricity; Teknisk fysik med inriktning mot elektricitetslära;

    Sammanfattning : Vertical-axis wind turbines (VAWTs) have with time been outrivaled by the today more common and economically feasible horizontal-axis wind turbines (HAWTs). However, VAWTs have several advantages which still make them interesting, for example, the VAWTs can have the drive train at ground level and it has been argued that they have lower noise emission.

  4. 14. Control over the Cloud : Offloading, Elastic Computing, and Predictive Control

    Författare :Per Skarin; Institutionen för reglerteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Cloud; Control Theory; Model Predictive Control; Offloading; Elastic Computing; Networks; Utility Computing; Cloud Services; Internet-of-Things; Distributed Cloud; 5G Systems;

    Sammanfattning : The thesis studies the use of cloud native software and platforms to implement critical closed loop control. It considers technologies that provide low latency and reliable wireless communication, in terms of edge clouds and massive MIMO, but also approaches industrial IoT and the services of a distributed cloud, as an extension of commercial-of-the-shelf software and systems.

  5. 15. Resource Allocation for Data-Intensive Services in the Cloud

    Författare :David Daharewa Gureya; Vladimir Vlassov; Joao Pedro Barreto; Gregory Chockler; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Cloud computing; QoS-aware resource allocation; Elasticity controller; Multi-socket systems; Non-uniform memory access; Page placement; Memory-intensive applications; Informations- och kommunikationsteknik; Information and Communication Technology;

    Sammanfattning : Cloud computing has become ubiquitous due to its resource flexibility and cost efficiency. Resource flexibility allows Cloud users to elastically scale their Cloud resources, for instance, by horizontally scaling the number of virtual machines allocated to each application as the application demands change.
