  3. 2. Enhancement of few-cycle light fields for relativistic nanophotonics

    Författare :Aitor de Andres Gonzalez; Laszlo Veisz; Ove Axner; Rodrigo Lopez-Martens; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Vacuum laser acceleration; spatio-spectral characterization; relativistic nanophotonics; optical parametric synthesis; fysik; Physics;

    Sammanfattning : Pulses of light that are both ultrashort and ultraintense are often generated using optical parametric amplifiers (OPA). These are capable of driving highly non-linear interactions with matter, which are interesting when studying the fundamental laws of our universe. LÄS MER

    Sammanfattning : Advancements in drug delivery have enabled a wider array of prevention, control and treatment of diseases such as cancer. Drug delivery systems have the possibility of encapsulating drugs with low solubility, delivering them to specific locations in the body as well as obtaining a controlled and sustained drug release.

  5. 4. Growth and Business Cycles -Swedish Manufacturing Industry 1952-2001

    Författare :Camilla Josephson; Lennart Schön; Deirdre Nansen MC Closkey; Ekonomisk-historiska institutionen; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Ekonomisk och social historia; Social and economic history; Nutidshistoria från 1914 ; Contemporary history since 1914 ; Manufacturing industry; Institutional change; Knowledge accumulation; Opportunity costs; The cointegrated VAR model; Business cycles; Economic growth; TFP growth; Cyclical economics; Konjunkturteori; cykliska förlopp; Contemporary history;

    Sammanfattning : This study shows that the mechanisms behind knowledge accumulation and the sources of productivity growth differ from industry to industry depending on what is produced and what technology is used. Although it is apparent to most researchers in the field that the only way to explain long-run growth in output per capita is through technological progress and accumulation of knowledge that counteract the dampening effect of diminishing returns, we are still in the dark about how such mechanisms operate.

  7. 5. Constitutive modelling of an additively manufactured alloy for fatigue lifing in high temperature applications

    Författare :Thomas Lindström; Daniel Leidermark; Håkan Hallberg; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : The main objective of the work presented in this Licentiate thesis is to investigate and model the cyclic behaviour of an additively manufactured ductile nickel-based superalloy, with special emphasis on modelling the stabilised material behaviour, which is of interest for fatigue life predictions. Cyclic fatigue tests at different temperatures have been performed to investigate the cyclic mechanical behaviour of the material, where specimens built in different orientations have been used to also study the anisotropic behaviour of the material.
