    Sammanfattning : Structural characterization is essential for the understanding of the magnetic properties of thin films and multilayers. In this thesis, both crystalline and amorphous thin films and multilayers were analyzed utilizing transmission electron microscopy (TEM). LÄS MER

  3. 2. Signal Processing Tools for Electron Microscopy

    Författare :Jakob Spiegelberg; Jan Rusz; Kristiaan Pelckmans; Peter M. Oppeneer; Johan Verbeeck; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : The detection of weak signals in noisy data is a problem which occurs across various disciplines. Here, the signal of interest is the spectral signature of the electron magnetic chiral dichroism (EMCD) effect. LÄS MER

  4. 3. Towards atomically resolved magnetic measurements in the transmission electron microscope : A study of structure and magnetic moments in thin films

    Författare :Hasan Ali; Klaus Leifer; Peter Van Aken; Uppsala universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Transmission electron microscope; thin films; magnetic moments; electron energy loss spectroscopy; simultaneous acquisition; electron magnetic circular dichroism; Teknisk fysik med inriktning mot materialanalys; Engineering Science with specialization in Materials Analysis;

    Sammanfattning : The magnetic properties of thin metallic films are significantly different from the bulk properties due to the presence of interfaces. The properties shown by such thin films are influenced by the atomic level structure of the films and the interfaces. LÄS MER

  5. 4. Human factors and wireless network applications : more bits and better bits

    Författare :Greger Wikstrand; Lars-Erik Janlert; Jerry Eriksson; Mark Högskolan Dalarna Ekonomi och samhälle Dougherty; Angela Sasse; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Human factors; Mobile multimedia; Access protocols; Computer network performance; Quality of service; Video conferencing; Computer games; Streaming video; Medium access control; Collision detection; Reliable multicast; Computer science; Datavetenskap;

    Sammanfattning : I avhandlingen beskrivs ett hypotetiskt system som kan användas av mobila användare, bland andra taxichaufförer, som exempelvis vill följa en viktig fotbollsmatch. Flera faktorer ställer till problem: Ibland står bilen still och föraren har inget annat att tänka på än matchen. LÄS MER
