  1. 1. Thin-walled steel studs in fire : analysis and design recommendations

    Författare :Peter Karlström; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Steel Structures; Stålbyggnad;

    Sammanfattning : Development of steel frame modular buildings is gaining increased popularity and support throughout Europe. Due to flexibility in construction and good long-term performance, lightweight steel frame structures are often preferred solutions, for instance in partitions and suspended ceilings as well as for load-bearing elements.

  3. 2. Sound Insulation at Low Frequencies

    Författare :Andrzej Pietrzyk; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Finite Element Method; numerical simulations; Modal Approach; sound insulation; sound reduction index; low frequency; building partitions;

    Sammanfattning : The airborne sound transmission through building partitions at low frequencies was studied. The definition of the sound reduction index as a measure of sound insulation has been examined by means of extensive numerical simulations in 3-D domains. The simulations were based on the wave theoretical acoustics. LÄS MER

  5. 4. Building Distributed Systems for High-Stress Environments using Reversibility and Phase-Awareness

    Författare :Ruma Paul; Vladimir Vlassov; Peter Van Roy; Alexander Reinefeld; KTH; []
    Nyckelord :Informations- och kommunikationsteknik; Information and Communication Technology;

    Sammanfattning : Large-scale applications for mobile devices and Internet of Things live in stressful real-world environments: they have both continuous faults and bursts of high faults. Typical faults are node crashes, network partitions, and communication delays. LÄS MER

  7. 5. A Middleware for Self-Managing Large-Scale Systems

    Författare :Constantin Adam; Rolf Stadler; Arun Iyengar; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; autonomic computing; self-organization; decentralized control; web services; quality of service; Telecommunication; Telekommunikation;

    Sammanfattning : This thesis investigates designs that enable individual components of a distributed system to work together and coordinate their actions towards a common goal. While the basic motivation for our research is to develop engineering principles for large-scale autonomous systems, we address the problem in the context of resource management in server clusters that provide web services.
