  1. 21. WRF-Chem vs machine learning approach to predict air quality in urban complex terrains: a comparative study

    Master-uppsats, Högskolan Dalarna/Mikrodataanalys

    Författare :Andrey Kudryashov; [2020]
    Nyckelord :Machine learning; WRF-Chem; comparative study; air quality;

    Sammanfattning : Air pollution is the main environmental health issues that affects all the regions and causes millions premature deaths every year. In order to take any preventive measures, we need the ability to predict pollution level and air quality. This task is conventionally solved using deterministic models. LÄS MER

  3. 22. Nyutexaminerad sjuksköterska : I okänd och komplex terräng

    Kandidat-uppsats, Högskolan i Borås/Akademin för vård, arbetsliv och välfärd

    Författare :Anna Högström; Amanda Kvant; [2019]
    Nyckelord :novice nurses; competence; experience; role adaption; development; transition; literature review; nyutexaminerad sjuksköterska; kompetens; upplevelse; rollanpassning; utveckling; övergång; litteraturöversikt;

    Sammanfattning : Att vara nyutexaminerad sjuksköterska ställer höga krav på kompetensutveckling och förmåga att klara övergången till en ny miljö. Sjuksköterskebrist råder hos samtliga arbetsgivare och det finns en utmaning i framtidens kompetensförsörjning. LÄS MER

  4. 23. Addressing intersection artifacts on textured, geometrically rendered vector data in 3D applications

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

    Författare :Bjarni Ragnar Gudmundsson; [2019]
    Nyckelord :;

    Sammanfattning : There exist various methods to render vector data in 3D applications. One such method is to render the data geometrically, where polyline data is tessellated into some geometry that is rendered on top of the 3D terrain. LÄS MER

  5. 24. Sound propagation modelling with applications to wind turbines

    Master-uppsats, KTH/Mekanik

    Författare :Julius Fritzell; [2019]
    Nyckelord :Sound propagation; Wind turbines; Wave equation; Helmholtz equation; Fourier transform; Chebyshev polynomials.;

    Sammanfattning : Wind power is a rapidly increasing resource of electrical power world-wide. With the increasing number of wind turbines installed one major concern is the noise they generate. Sometimes already built wind turbines have to be put down or down-regulated, when certain noise levels are exceeded, resulting in economical and environmental losses. LÄS MER

  7. 25. Propagation of Radio Waves in a Realistic Environment using a Parabolic Equation Approach

    Master-uppsats, Linköpings universitet/Teoretisk Fysik

    Författare :Jonas Ehn; [2019]
    Nyckelord :Electromagnetic fields; wave propagation; radar; parabolic equation; split-step Fourier method;

    Sammanfattning : Radars are used for range estimation of distant objects. They operate on the principle of sending electromagnetic pulses that are reflected off a target. This leads to the propagation of electromagnetic waves over large distances. As the waves propagate, they are affected by several aspects that decrease the performance of the radar system. LÄS MER
