  1. 1. Using blue light reflectance from high-resolution images (6000 dpi) of Scots pine tree rings to reconstruct three centuries of Scottish summer temperatures

    Kandidat-uppsats, KTH/Hållbar utveckling, miljövetenskap och teknik

    Författare :Alice De Schutter; Karin Markendahl; [2021]
    Nyckelord :summer temperature reconstruction; climate change; Scotland; Scots pines; ultra-high image resolution; blue intensity; rekonstruktion av sommartemperatur; klimatförändringar; Skottland; skotska tallar; hög bildupplösning; blå intensitet;

    Sammanfattning : Advances in scanner technology have made it possible to obtain high resolution (6000 dpi) images of tree samples. Due to the images’ increased capability of resolving anatomical wood structures, the new technology could be of benefit to dendroclimatology.  This study attempts to expand on Rydval et al. LÄS MER

  3. 2. How ionized radicals bind to Ir(111) supported graphene

    Kandidat-uppsats, Lunds universitet/Fysiska institutionen; Lunds universitet/Synkrotronljusfysik

    Författare :David Johansson; [2018]
    Nyckelord :Graphene; Radicals; Physics and Astronomy;

    Sammanfattning : In this thesis radical adsorption onto Ir(111) supported graphene at room temperature is studied using scanning tunneling microscopy. The radicals were formed in by thermal cleavage of C2H4 molecules. LÄS MER

  4. 3. RFI Suppression in Low Frequency UWB SAR Using the RLS Algorithm

    Master-uppsats, Blekinge Tekniska Högskola/Sektionen för ingenjörsvetenskap

    Författare :Khan Fazal Ullah; [2010]
    Nyckelord :Aperture; Adaptive Line Enhancement ALE ; Chirp signal; Global BackProjection GBP ; Pulse compression; Radio Frequency Interference RFI ; Synthetic Aperture Radar SAR ; UltraWide Band UWB ;

    Sammanfattning : Synthetic Aperture Radar (SAR) has many applications within ground image sensing and navigation. UltraWide Band(UWB) SAR operating at Ultra High Frequency /Very High Frequency(UHF/VHF) are usually a ffected by the Radio Frequency Interferences(RFI) from civilian communication bands which causes SIR(Signal to Interference Ratio) to go down.
