  1. 1. Methodologies for Approximation of Unary Functions and Their Implementation in Hardware

    Författare :Erik Hertz; Bertil Svensson; Peter Nilsson; Eric Järpe; Michael Faulkner; Högskolan i Halmstad; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : Applications in computer graphics, digital signal processing, communication systems, robotics, astrophysics, fluid physics and many other areas have evolved to become very computation intensive. Algorithms are becoming increasingly complex and require higher accuracy in the computations. LÄS MER

  4. 3. Nanofabrication of Diffractive Soft X-ray Optics

    Författare :Magnus Lindblom; Hans M. Hertz; Erik H. Anderson; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Nanofabrication; Zone plate; x-ray; diffractive x-ray optics; x-ray microscopy; Optics; Optik; Physics; Fysik;

    Sammanfattning : This thesis summarizes the present status of the nanofabrication of diffractive optics, i.e. zone plates, and test objects for soft x-ray microscopy at KTH. The emphasis is on new and improved fabrication processes for nickel and germanium zone plates. LÄS MER

  5. 4. Ultra-fast dynamics in atoms and molecules during photoionization: from attoseconds to femtoseconds

    Författare :Erik Månsson; Synkrotronljusfysik; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; photoelectron spectroscopy; momentum imaging; coincident detection; correlation; direct double ionization; Born–Oppenheimer approximation; high harmonics; synchrotron radiation; Fysicumarkivet A:2014:Månsson;

    Sammanfattning : Treating the correlated behaviour of multiple particles is challenging for both theory and experiment. This thesis reports on a variety of experimental investigations aiming to advance the understanding of fundamental processes in atoms and molecules: double ionization, isomerization and dissociation.

  7. 5. Vehicle Disc Brake Roughness Noise : Experimental Study of the Interior Noise andVibro-Acoustic Modelling of Suspension Systems

    Författare :Eskil Lindberg; Nils-Erik Hörlin; Peter Göransson; Wolfgang Kropp; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; acoustics; disc brake; surface topography; wire brush noise; roughness noise; component mode synthesis; vehicle suspension;

    Sammanfattning : Prediction of vehicle disc brake roughness noise is a non-trivial challenge. In fact, neither the source mechanisms, nor the transfer paths are so far well understood. LÄS MER
