  1. 6. Forest Aboveground Biomass Monitoring in Southern Sweden Using Random Forest Modelwith Sentinel-1, Sentinel-2, and LiDAR Data

    Magister-uppsats, Högskolan i Gävle/Samhällsbyggnad

    Författare :Wan Ni Lin; [2023]
    Nyckelord :Aboveground biomass; Sentinel-1; Sentinel-2; LiDAR; random forest; GEE;

    Sammanfattning : Monitoring carbon stock has emerged as a critical environmental problem among several worldwide organizations and collaborations in the context of global warming and climate change. This study seeks to provide a remote sensing solution based on three types of data, to explore the feasibility and reliability of estimating aboveground biomass (AGB) in order to improve the efficiency of monitoring carbon stock.

  3. 7. Mapping edge vegetation in connection to beech forest to locate potential habitats for red-listed beetles in Scania, Sweden

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

    Författare :Lovisa Rosenquist Ohlsson; [2022]
    Nyckelord :forest; temperate broadleaved forest; beech; biodiversity; edge vegetation; southern Sweden; Scania; beetles; Natura 2000; Fagus sylvatica; Stictoleptura scutellata; Ischnomera sanguinicollis; Earth and Environmental Sciences;

    Sammanfattning : The number of species classified as red-listed has increased by 11% between 2015 and 2020, with beetles and butterflies being especially affected. Among these are the vulnerable longhorned beetle (Stictoleptura scutellata) and the endangered false blister beetle (Ischnomera sanguinicollis). LÄS MER

  4. 8. Multi-spectral X-ray imaging with a laser-plasma accelerator

    Master-uppsats, Lunds universitet/Atomfysik; Lunds universitet/Fysiska institutionen

    Författare :Andrea Angella; [2022]
    Nyckelord :Multi-spectral imaging; single-photon counting; X-ray absorption spectroscopy; XAS; LWFA; laser-wakefield acceleration; K-edge; imaging; metal-detection algorithm; Physics and Astronomy;

    Sammanfattning : This master thesis focuses on the creation of an algorithm to perform multispectral imaging of a metallic target using X-rays. The generation of an ultrashort high-power low-divergent X-ray beam is performed by means of a Ti:Sapphire laser driven wake-field plasma accelerator. LÄS MER

  5. 9. Geometry studies of high energy 16O collisions

    Kandidat-uppsats, Lunds universitet/Teoretisk partikelfysik - Geonomgår omorganisation

    Författare :Aliaksei Kuzmenka; [2022]
    Nyckelord :Ion Collisions; Oxygen; Physics and Astronomy;

    Sammanfattning : In this project a model of oxygen, 16O, nuclei, where the nucleons are organised in α-clusters, was implemented in the Pythia Monte Carlo event generator. To study the effects of the new model, some observables, such as the distribution of the number of the wounded nucleons, charged particle multiplicity in the forward and central pseudorapidity region, and the pseudorapidity distribution for different centrality bins and eccentricity, are compared to the model originally implemented in Pythia (Woods-Saxon).

  7. 10. The “ultramafic” Intrusion’s within the peridotite from Härbergsdalen : Petrological characterization of infiltration record within the lithospheric mantle

    Kandidat-uppsats, Uppsala universitet/Mineralogi, petrologi och tektonik

    Författare :Per Volter; [2022]
    Nyckelord :;

    Sammanfattning : The mantle constitutes ~80% of Earths volume, however, due to its location deep beneath Earth’s surface the mantle is inaccessible to study in situ. Despite this, we still have information about its composition thanks to seismic studies which haven proven the mantle to be in generally homogenous and dominated by a rock called peridotite. LÄS MER
