  1. 6. Impedance and Instabilities in the MAX IV 3 GeV Ring

    Författare :Galina Skripka; Lunds universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Collective effects; geometric impedance; resistive wall impedance; wakefields; particle tracking; harmonic cavity;

    Sammanfattning : To ensure the beam with an ultralow emittance and high current the possible effects deteriorating the beam stability must be investigated. When ultrarelativistic particles travel in the vacuum chamber they induce electromagnetic fields which can act back on them and the following particles. LÄS MER

    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; angle brackets with a rib; annular ring nails; metal works for timber structures; static load tests of joints; numerical simulations of tests of joints; analytical static models of joints.; úhelníky s prolisem; kroužkové konvexní hřebíky; kování pro přípoje dřevostaveb; statické zatěžovací zkoušky přípojů; numerické simulace zkoušek přípojů; analytické statické modely přípojů.;

    Sammanfattning : The thesis deals with appropriate methods to determinate load-bearing capacities of timber structures joints using angle brackets with a rib. In these joints, annular ring nails were used as connectors.During an experimental approach, full-scale load tests of whole joints were performed. LÄS MER

  4. 8. Annealed Glass Failure Modelling : A Weakest-Link Approach with Statistical Analysis

    Författare :David Kinsella; Byggnadsmekanik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; glass strength; structural glass; Weibull distribution; weakest-link system; statistical analysis; experimental tests; numerical modelling; finite element method; fracture mechanics;

    Sammanfattning : Novel and increased use of glass in building construction has been made possible, as a result of methods of mass production introduced during the 20th century and advanced computational structural analyses. With modern use of glass structures, a range of demands emerge which need to be addressed in the strength design process. LÄS MER

  7. 10. Design, fabrication and characterization of plasmonic components based on silicon nanowire platform

    Författare :Fei Lou; Lech Wosinski; Lars Thylén; Sebastian Lourdudoss; Anatoly Zayats; KTH; []
    Nyckelord :Planar integrated circuit; silicon photonics; plasmonics; subwavelength; directional coupler; polarization beam splitter; disk resonator; ring resonator; finite-difference time-domain; photonic crystal; electro-optic polymer; Purcell factor.;

    Sammanfattning : Optical interconnects based on CMOS compatible photonic integrated circuits are regarded as a promising technique to tackle the issues traditional electronics faces, such as limited bandwidth, latency, vast energy consumption and so on. In recent years, plasmonic integrated components have gained great attentions due to the properties of nano-scale confinement, which may potentially bridge the size mismatch between photonic and electronic circuits.
