  1. 1. Phenomenology of Diffractive Higgs Production and Large Extra Dimensions

    University dissertation from Department of Theoretical Physics, Lund University

    Author : Malin Sjödahl; Lund University.; Lunds universitet.; [2006]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; ADD; black holes; gravitational scattering; quantum field theory; Elementary particle physics; LHC; cosmic rays; Kosmisk strålning; högenergi; High energy interactions; kvantfältteori; Elementarpartikelfysik; Higgs; large extra dimensions; Diffractive;

    Abstract : This thesis is based on phenomenological predictions for high energy particle collisions from two different theoretical models. The first two papers deal with uncertainties in exclusive reactions of type proton + proton -> proton + proton + Higgs. READ MORE

  2. 2. Coherent Diffractive Imaging with X-ray Lasers

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Max Felix Hantke; Uppsala universitet.; [2016]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; coherent diffractive X-ray imaging; lensless imaging; coherent X-ray diffractive imaging; flash diffractive imaging; single particle imaging; aerosol injection; electrospray injection; substrate-free sample delivery; carboxysome; phase retrieval; X-ray diffraction software; X-ray free-electron laser; XFEL; FEL; CXI; CDI; CXDI; FXI;

    Abstract : The newly emerging technology of X-ray free-electron lasers (XFELs) has the potential to revolutionise molecular imaging. XFELs generate very intense X-ray pulses and predictions suggest that they may be used for structure determination to atomic resolution even for single molecules. READ MORE

  3. 3. Algorithms for Coherent Diffractive Imaging with X-ray Lasers

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Benedikt J. Daurer; Uppsala universitet.; [2017]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; X-ray lasers; coherent diffractive imaging; algorithms; lensless imaging; flash diffractive imaging; flash X-ray imaging; aerosol injection; FEL; XFEL; CXI; CDI; FXI; Physics with specialization in Biophysics; Fysik med inriktning mot biofysik;

    Abstract : Coherent diffractive imaging (CDI) has become a very popular technique over the past two decades. CDI is a "lensless" imaging method which replaces the objective lens of a conventional microscope by a computational image reconstruction procedure. READ MORE

  4. 4. Ultrafast Coherent X-ray Diffractive Nanoimaging

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Filipe R. N. C. Maia; Uppsala universitet.; [2010]
    Keywords : XFEL; Phasing; Image Reconstruction; Single Particle Imaging; Ultrafast Diffraction; X-ray diffraction; Coherent Diffractive Imaging; CXDI;

    Abstract : X-ray lasers are creating unprecedented research opportunities in physics,chemistry and biology. The peak brightness of these lasers exceeds presentsynchrotrons by 1010, the coherence degeneracy parameters exceedsynchrotrons by 109, and the time resolution is 105 times better. READ MORE

  5. 5. Microsystems Technology for Underwater Vehicle Applications

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Jonas Jonsson; Uppsala universitet.; [2012]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Aquatic; Submersible; Underwater; Micro; Miniaturized; Sonar; Sidescan; Topography; Laser; Diffractive; Optics; Sampler; Particle; Microorganism; Acoustic; Enriching; Conductivity; Temperature; Depth; CTD; Flow; Teknisk fysik med inriktning mot mikrosystemteknik; Engineering Science with specialization in Microsystems Technology;

    Abstract : The aim of this thesis work has been to investigate how miniaturization, such as microsystems technology, can potentially increase the scientific throughput in exploration of hard-to-reach underwater environments, such as the subglacial lakes of Antarctica, or other challenging environments, including cave systems and wrecks. A number of instruments and subsystems applicable to miniature submersibles have been developed and studied, and their potential to provide a high functionality density for size-restricted exploration platforms has been assessed.
