  1. 1. Feasibility study of dam deformation monitoring in northern Sweden using Sentinel1 SAR interferometry

    Magister-uppsats, Högskolan i Gävle/Samhällsbyggnad, GIS

    Författare :Cecilia Borghero; [2018]
    Nyckelord :SAR interferometry; Sentinel-1A; dam deformation monitoring;

    Sammanfattning : Dams are man-made structures that in order to keep functioning and to be considered structurally healthy need constant monitoring. Assessing the deformation of dams can be time consuming and economically costly. LÄS MER

  2. 2. Climate Change in Kenya : a review of literature and evaluation of temperature and precipitation data

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

    Författare :Marie Vigren Skogseid; [2017]
    Nyckelord :climate change; Kenya; East Africa; temperature trends; precipitation patterns; extreme weather; Earth and Environmental Sciences;

    Sammanfattning : The world is facing serious and complex impacts with regard to climate change. Natural and human settlements on all continents are affected, and the African continent is considered as one of the most vulnerable areas due to rapid urbanization growth and high dependency on rain-fed agriculture, amongst others.

  3. 3. Fundamental physical testing of rattle - Design and evaluation of a rattle producing test rig

    H-uppsats, Chalmers tekniska högskola/Institutionen för tillämpad mekanik

    Författare :Axel Svensson; Jonathan Hasselström; [2017]
    Nyckelord :;

    Sammanfattning : Squeak and rattle is a cause of high warranty costs and a driver behind the productionof pre-series cars for subjective evaluation. An important feature for apremium car brand is a high perceived quality and consequently the lack of squeakand rattle issues. LÄS MER

  4. 4. Finite element analysis of thermal fields during repair welding of discrete rail defects

    H-uppsats, Chalmers tekniska högskola/Institutionen för tillämpad mekanik

    Författare :Michele Maria Maglio; [2017]
    Nyckelord :;

    Sammanfattning : Discrete defects in a rail head may form due to aggressive wheel–rail contact in terms of thermal and/or mechanical loads, or due to indentations from foreign objects trapped in the contact. If large, such defects need to be repaired or the rail section removed. These are costly operations that cause operational disturbances. LÄS MER

  5. 5. The Shape of Copper Oxide Clusters Under Oxygen Excess: A Genetic Algorithm Search

    H-uppsats, Chalmers tekniska högskola/Institutionen för fysik (Chalmers)

    Författare :Oskar Larsson; [2017]
    Nyckelord :copper oxide clusters; DFT; density functional theory; PBE; genetic algorithm; free energy;

    Sammanfattning : The stability of copper oxide clusters was investigated using density functional theory (DFT) where the exchange-correlation was described by the Perdew-Burke-Ernzerhof generalized gradient approximation. In particular, the Cu1–3O1–6 and [Cu6O3–9]+/− clusters were investigated. LÄS MER
