  1. 6. Residual generation for fault diagnosis

    Författare :Erik Frisk; Lars Nielsen; Linköpings universitet; []
    Nyckelord :TECHNOLOGY; TEKNIKVETENSKAP;

    Sammanfattning : The objective when supervising technical processes is to alarm an operator when a fault is detected and also identify one, or possibly a set of components, that may have been the cause of the alarm. Diagnosis is an expansive subject, partly due to the fact that nowadays, more applications have more embedded computing power and more available sensors than before. LÄS MER

  3. 7. Acquisition strategies for fat/water separated MRI

    Författare :Henric Rydén; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : This thesis focuses on new ways to more efficiently acquire the signal for fat/water separated MRI, also known as Dixon methods. In paper I, the concept of dual bandwidths was introduced to improve SNR efficiency by removing dead times in a spin echo PROPELLER sequence. LÄS MER

  4. 8. Whiteness and Fluorescence in Layered Paper and Board : Perception and Optical Modelling

    Författare :Ludovic Gustafsson Coppel; Per Edström; Caisa Johansson; Markku Hauta-Kasari; Mittuniversitetet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Whiteness; Perception; Colour Appearance Modelling; Paper Optics; Light Scattering; Fluorescence; Lateral Light Scattering; White-Top Mottle; Kubelka-Munk; Radiative Transfer;

    Sammanfattning : This thesis is about modelling and predicting the perceived whiteness of plain paper from the paper composition, including fluorescent whitening agents. This involves psychophysical modelling of perceived whiteness from measurable light reflectance properties, and physical modelling of light scattering and fluorescence from the paper composition.

  5. 9. Dynamics and Intrinsic Variability of Spintronic Devices

    Författare :Corrado Carlo Maria Capriata; B. Gunnar Malm; Per-Erik Hellström; Dan Kuylenstierna; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Spintronics; micromagnetic simulations; SHNO; MTJ; microwave measurements; realistic simulations; low-temperature measurements; fabrication; grains; Spinntronik; mikromagnetiska simuleringar; SHNO; MTJ; mikrovågsmätningar; realistiska simuleringar; lågtemperaturmätningar; nanotillverkning; korn; Informations- och kommunikationsteknik; Information and Communication Technology;

    Sammanfattning : Spintronics is a scientific domain focusing on utilizing electron spin for information processing. This is the element that distinguishes it from electronics, which only utilizes the charge of electrons. LÄS MER

  7. 10. Chinese women and consumer culture : discourses on beauty and identity in advertising and women's magazines 1985-1995

    Författare :Perry Johansson; Frank Dikötter; Stockholms universitet; []
    Nyckelord :HUMANITIES and RELIGION; HUMANIORA och RELIGIONSVETENSKAP; sinologi; Sinology;

    Sammanfattning : Chinese women and consumer culture are studied through semiotics and discourse analysis of advertisements and beauty editorials from women's magazines. The trajectory of Chinese consumption and advertising development during the last two decades is outlined and the changing notions of female beauty after Mao is examined, describing the resurfacing gender differences and the renewed importance of body and gender, together with the commodification of women and female beauty.
