  1. 1. Inversion of SkyTEM Data Based on Geophysical Logging Results for Groundwater Exploration in Örebro, Sweden

    Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Geovetenskap och miljöteknik

    Författare :Andrée Kindlund; [2021]
    Nyckelord :SkyTEM; hydrogeophysics; geophysical logging; A priori; groundwater exploration;

    Sammanfattning : Declining groundwater tables threatens several municipalities in Sweden which drinking water is collected from. To ensure a sound drinking water supply, the Geological Survey of Sweden has initiated a groundwater exploration plan. LÄS MER

  3. 2. The effects of backlash on the frequency stability in a hydro based power system

    Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Niklas Ung; [2018]
    Nyckelord :;

    Sammanfattning : The generated and consumed power should always be in balance in a power system. Any energy from a power imbalance will be stored as kinetic energy in the system's rotating mass leading to a changed frequency. To keep the frequency within acceptable limits hydropower plants are used to counteract power imbalances. LÄS MER

  4. 3. Predicting Railway-Induced Ground Vibrations

    Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/Byggnadsmekanik; Lunds universitet/Institutionen för byggvetenskaper

    Författare :Nils Persson; [2016]
    Nyckelord :ground vibrations; railway; train; wave propagation; vibration measurements; finite element method; dynamics; Technology and Engineering;

    Sammanfattning : Population growth and densification lead to growing urban environments. Unbuilt land within cities can be used to construct residences and other facilities. Population growth can further lead to a greater demand of transportation, which can require expansion of transportation systems such as railways or road traffic. LÄS MER

  5. 4. An Evaluation of Interpolation and Oversampling Effects on Image Quality in Synthetic Aperture Radar Processing with Global Back-projection

    Magister-uppsats, Blekinge Tekniska Högskola/Institutionen för tillämpad signalbehandling

    Författare :Andreas Hartman; [2014]
    Nyckelord :Synthetic Aperture Radar; Global Back-projection; Image Quality; Side Lobe Suppression;

    Sammanfattning : For time domain SAR processing algorithms, such as Global Back-projection, interpolation becomes a part of the implementation. In order for the interpolation to yield good results, the oversampling rate used in the sampling of the original data may constitute an important factor. LÄS MER

  7. 5. Analysis and verification of routing effects on signal integrity for high-speed digital stripline interconnects in multi-layer PCB designs

    Kandidat-uppsats, Institutionen för systemteknik; Tekniska högskolan

    Författare :Andreas Frejd; [2010]
    Nyckelord :Signal integrity; PCB; digital interconnect; high-speed; microwave probing; EM field solver;

    Sammanfattning : The way printed circuit board interconnects for high-speed digital signals are designed ultimately determines the performance that can be achieved for a certain interface, thus having a profound impact on whether the complete communication channel will comply with the desired standard specification or not. Good understanding and methods for anticipating and verifying this behaviour through computer simulations and practical measurements are therefore essential. LÄS MER
