  1. 1. Effects of cracking of coupling beams onhigh rise towers subjected to wind load

    Master-uppsats, KTH/Betongbyggnad

    Författare :Brook Worku Woldemikael; [2020]
    Nyckelord :Crack; reinforcement content; aspect ratio; shear deformation; joint flexibility; concrete grade; effective stiffness.; Sprickor; förstärkningsinnehåll; tvärsnittsförhållande; skjuvdeformation; ledflexibilitet; betongkvalitet; effektiv styvhet;

    Sammanfattning : In high rise towers, reinforced concrete elevator shafts with coupling beams are extensively used as a principal structural element to resist lateral loads. The lateral load resistance of the tower is dominantly dependent on the stiffness of the load-bearing walls, and coupling beams connecting them. LÄS MER

  3. 2. Applying Multivariate Expected Shortfall on High Frequency Foreign Exchange Data

    Master-uppsats, KTH/Matematisk statistik

    Författare :Sara Holmsäter; Emelie Malmberg; [2016]
    Nyckelord :Multivariate Expected Shortfall; Component Expected Shortfall;

    Sammanfattning : This thesis aims at implementing and evaluating the performance of multivariate Expected Shortfall models on high frequency foreign exchange data. The implementation is conducted with a unique portfolio consisting of five foreign exchange rates; EUR/SEK, EUR/NOK, EUR/USD, USD/SEK and USD/NOK. LÄS MER

  4. 3. Lipid bilayers and their interactions with the antimicrobial peptide LL37: a TIR Raman study

    Master-uppsats, KTH/Skolan för kemivetenskap (CHE)

    Författare :Rebecca Jacob; [2016]
    Nyckelord :TIR; Raman; LL37; lipid; bilayers; antimicrobial; peptide; AMP; resistance; antibiotics; DMPC; DOPC; DOPE; DOPG;

    Sammanfattning : As a direct consequence of the misuse of antibiotics since its first discovery, bacteria have developed extensive resistance mechanisms making them once again potential lethal threats. This eventuality has triggered a vast research effort from scientists worldwide to find solutions to mitigate antimicrobial resistance. LÄS MER

  5. 4. Snow and sea ice temperature profiles from satellite data and ice mass balance buoys

    Master-uppsats, Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Författare :Isabella Grönfeldt; [2016]
    Nyckelord :IMB; ice mass balance buoys; snow-ice interface; air-snow interface; temperature profile; snow; sea ice; Fram Strait; Greenland; Arctic Ocean; climate change; climate; physical geography and ecosystem analysis; remote sensing; satellite; sensor; SMOS; AMSR-2; TIR; numerical weather prediction; multiple regression analysis; Earth and Environmental Sciences;

    Sammanfattning : The sea ice covers approximately 5% of the Earth’s surface at any given time and it plays an important role in the polar climate system affecting the heat, mass and momentum exchange between the atmosphere and the ocean. The snow cover on top of the sea ice affects its insulating and reflective properties and thus key figures in the climate system feedback loop. LÄS MER

  7. 5. Zinc abundances of stars in the Milky Way

    Kandidat-uppsats, Lunds universitet/Astronomi - Genomgår omorganisation

    Författare :Max Haase; [2015]
    Nyckelord :zinc abundances; Physics and Astronomy;

    Sammanfattning : In this work we study the spectra of 423 stars in the Milky Way disk in order to determine their zinc abundances. The methodology to determine elemental abundances consists of synthesising sets of spectra with varying zinc abundances and comparing them with the observed spectra to find the best fit. LÄS MER
