  1. 1. Modeling wave behavior with linear wave theory

    University essay from Umeå universitet/Institutionen för fysik

    Author : Elsa Renström; [2024]
    Keywords : ;

    Abstract : This thesis aimed to look at the behaviours of the water beneath waves from a modeling and simulations point of view. We have investigated how to use Linear wave theory (LWT) to model the kinematic movements in water governed by free ocean waves. The model assumes the surface to consist of a superposition of sinusoidal waves. READ MORE

  2. 2. A Geophysical Survey of Northern Utö

    University essay from Stockholms universitet/Institutionen för geologiska vetenskaper

    Author : Nicole Flanders; [2023]
    Keywords : ;

    Abstract : A geophysical investigation on the northern part of Utö was carried out between 2020 and 2021 to asses the extent of the iron ore (BIFs) and the iron bearing sulfides that have been surveyed and mined in the past. The survey using analog field equipment combined magnetometry, gravimetry, susceptibility, leveling, density, and thin-section microscopy. READ MORE

  3. 3. Methods for determining focal point and delay for ultrasound arrays and multichannel electronics

    University essay from Lunds universitet/Avdelningen för Biomedicinsk teknik

    Author : Svante Rosenlind; [2023]
    Keywords : Focusing algorithms; k-wave; Spatiotemporal inverse filter; Gerchberg- Saxton algorithm; Focused ultrasound; Technology and Engineering;

    Abstract : High intensity focused ultrasound is a growing technique for tissue ablation, among other uses, and given its destructive capabilities, there is a need for control of where the energy is delivered. There exist a number of methods for focusing such ultrasound arrays, but these often assume prior knowledge of the impulse response, or require extensive full-system simulations. READ MORE

  4. 4. Using a GIS to enable an economic, land use and energy output comparison between small wind powered turbines and large-scale wind farms: the case of Oslo, Norway.

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Author : Colin Potter; [2023]
    Keywords : Geography; GIS; Wind power; Renewable energy sources; urban wind energy; urban areas; planning; vertical axis wind turbines; comparative studies; urban integrated energy systems; Oslo; Roan; Earth and Environmental Sciences;

    Abstract : Responding to an identified knowledge gap, the study aims to determine if smaller wind turbines located on top of existing urban buildings are more resource efficient (land utilization and economically) than large scale wind farms. To answer this question, using a GIS, the resource efficiency of the Roan wind farm in Northern Norway was compared to a theoretical modeled installation of small-scale wind turbines on top of buildings within a 2km radius study zone in central Oslo.

  5. 5. Unearthing the social-ecological cascades of the fall armyworm invasion: A computer-assisted text analysis of digital news articles

    University essay from Stockholms universitet/Stockholm Resilience Centre

    Author : Kathryn Bjorklund; [2023]
    Keywords : emerging pests and pathogens; social-ecological cascades; fall armyworm; Spodoptera frugiperda; structural topic modeling;

    Abstract : Understanding the complex nature of social-ecological cascades, or chain reactions of events that lead to widespread change in a system, is crucial for navigating the challenges they present. Emerging pests and pathogens, such as the fall armyworm, provide an opportunity to study these cascades in greater detail. READ MORE
