  1. 1. Mechanical Behaviour of Single-Layer Adhesive Joints : an integrated approach

    Författare :Li Högberg; Högskolan i Skövde; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; adhesive layer; beam adhesive layer model; energy release rate; fracture; integrated; Engineering mechanics; Teknisk mekanik; Teknik; Technology;

    Sammanfattning : Innovative products that are competitive on the market are likely to employ newtypes of materials and unusual geometries. A method that can assemble dissimilarmaterials and irregular geometries cost-effectively and at the same time offera joint that is light in weight and imperceptible, is optimal. LÄS MER

  3. 2. Single layer near-field acoustic imaging in space-invariant reflective environments

    Författare :Elias Zea; Ines Lopez Arteaga; Efren Fernandez-Grande; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; near-field acoustic holography; field separation techniques; single layer; space-invariance; reflective envirionments; närfält akustisk holografi; fältseparationstekniker; enkelt lager; utrymmes invarians; reflekterande miljöer; Vehicle and Maritime Engineering; Farkostteknik;

    Sammanfattning : The visualization of optical fields, or widely known as photography, is a common practice that can also be applied to acoustic fields. No less than three decades of research in acoustic imaging demonstrate its potential and relevance in plenty applications such as sound source identification and localization, as well as characterization of noise generation mechanisms.

  4. 3. Modelling of a single layer graphene membrane

    Författare :Kaveh Samadikhah; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Graphene membranes; Computational homogenization; Shell-membrane theory; Tersoff–Brenner potential.; Multiscale solution;

    Sammanfattning : The present contribution deals with the modeling of thin graphene membranes. Such membranes have a significant electrical and physical properties used for nano or microdevices like resonators and Atomic Force/mass Measurements (AFM) [1]. The membrane is considered as a homogenized graphene monolayer on the macroscopic structural scale. LÄS MER

  5. 4. Optical Studies of Single Quantum Dots

    Författare :Jonas Persson; Fasta tillståndets fysik; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; nano-optics; quantum optics; photoluminescence; micro-photoluminescence; single photon generation; Semiconductory physics; Halvledarfysik; low-dimensional structures; quantum dots; Stranski-Krastanow; Fysicumarkivet A:2004:Persson;

    Sammanfattning : This thesis presents spectroscopic studies of single self-assembled InP quantum dots (QDs). The electronic properties of these QDs have been studied by photoluminescence (PL) and scanning tunnelling luminescence (STL). The QDs were grown in the Stranski-Krastanow mode and were embedded in GaInP. LÄS MER

  7. 5. Airborne sound insulation of single and double plate constructions

    Författare :Ulrica Kernen; Gudni Jóhannesson; Waldemar Maysenhölder; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Construction engineering; : Airborne sound insulation; single plate; double plate; floating-floor; sound reduction index; sound transmission.; Byggnadsteknik; Building engineering; Byggnadsteknik;

    Sammanfattning : The sound insulation demands for dwellings and public building has increased over the years as the number of sound sources has grown. From the outside our homes are exposed to noise from cars, trains, airplanes, etc. Noise intrudes from our neighbours and their television and stereo equipments. LÄS MER
