  1. 1. Effects of clear-cut logging on five old-growth forest bryophyte species. : How does the most common forestry method in Sweden impact vulnerable forest specialists?

    Master-uppsats, Karlstads universitet/Fakulteten för hälsa, natur- och teknikvetenskap (from 2013)

    Författare :Nathalie Edwards; [2023]
    Nyckelord :Bryophytes; old-growth forests; forestry; nature conservation; sustainable forestry; mossor; gammelskog; skogsbruk; naturvård; hållbart skogsbruk;

    Sammanfattning : Clear-cut logging is the most widely practised forestry method in Sweden. This often conflicts with nature conservation and leads to issues where economic interests are pitted against ecological values. LÄS MER

  3. 2. Estimating Relative Position and Orientation Based on UWB-IMU Fusion for Fixed Wing UAVs

    Master-uppsats, Linköpings universitet/Reglerteknik

    Författare :Daniel Sandvall; Eric Sevonius; [2023]
    Nyckelord :UWB; Relative positioning; Sensor fusion; UAV; Formation flight; Fixed wing; Relative localization; EKF; FGO;

    Sammanfattning : In recent years, the interest in flying multiple Unmanned Aerial Vehicles (UAVs) in formation has increased. One challenging aspect of achieving this is the relative positioning within the swarm. LÄS MER

  4. 3. FEM Analysis of paperboard packaging

    Master-uppsats, KTH/Hållfasthetslära

    Författare :Wen-Che Li; [2022]
    Nyckelord :;

    Sammanfattning : The work aims to provide a finite element model using Ansys Workbench for realistically simulating paperboard packages. The geometrical properties of a package and the loading conditions were altered to investigate their influence on the box behavior and the applicability of Ansys as the finite element solver for paperboard material.

  5. 4. Transmission Systems for Grid Connection of Offshore Wind Farms : HVAC vs HVDC Breaking Point

    Uppsats för yrkesexamina på avancerad nivå,

    Författare :Jesper Larsson; [2021]
    Nyckelord :Wind power; Offshore wind; Power systems; Transmission; HVAC; Reactive power; HVDC; VSC; MMC; Breaking point; LCOE; NPV;

    Sammanfattning : Offshore wind is rapidly growing and optimised grid connections are crucial for its success. Generally, costs and losses are higher for HVDC at short distances due to the converters, while HVAC costs and losses increase more rapidly with distance due to the ac cables. LÄS MER

  7. 5. Kraftsamling vid ubåtsattacker : En teoriprövande fallstudie på ubåtsattacker under andra världskriget

    Uppsats för yrkesexamina på grundnivå, Försvarshögskolan

    Författare :Emanuel Arnesson; [2017]
    Nyckelord :Krigföringens grundprinciper; Kraftsamling; Clausewitz; Liddell Hart; Collins; Vego;

    Sammanfattning : Many theorists have discussed the question of the fundamental principles of warfare. But the importance of the principle of concentration of force for warfare is controversial and the theories about the principle are too general to say something about the reality. LÄS MER
