  1. 31. Water quality improvement of highway runoff by the filter material D-Rainclean : A five-month field trial

    Master-uppsats, KTH/Hållbar utveckling, miljövetenskap och teknik

    Författare :William Gulding; [2023]
    Nyckelord :Adsorption; D-Rainclean; metal removal; Reactive filter; stormwater treatment;

    Sammanfattning : Highway runoff and its pollutants are of growing concern. These pollutants require treatment as their concentration often are increased. A common removal method is the use of sedimentation ponds that removes particulates through gravity. LÄS MER

  3. 32. The design of a hydraulic equalizer bar for the feeding mechanism on forest harvester heads

    Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Författare :Arvid Söderlund; [2023]
    Nyckelord :Harvester; Harvester head; Komatsu Forest; Hydraulics; Equalizer bar; Parallellstag; Stag; Skogsmaskin; Skördare; Aggregat; Skog;

    Sammanfattning : Due to the importance of a correct tree placement and the wear that occurs to equalizer bars inharvester heads, Komatsu Forest AB in Umeå was interested if the bar could be replaced with ahydraulic system. According to Komatsu, the problems were that the equalizer bars that are responsible forsynchronizing the delimbing knives and feeding mechanism add weight, take up space and have atendency to break before their life expectancy.

  4. 33. Utvärdering av hydraulisk simulering som metod för habitatskattning för lax och öring

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Luft-, vatten- och landskapslära

    Författare :Oscar Axelsson; [2023]
    Nyckelord :Habitat mapping; ecohydraulics; Atlantic salmon; brown trout; habitatkartering; ekohydraulik; lax; öring;

    Sammanfattning : As all of Sweden's hydropower is to be re-examined within a 20-year period, methods are needed to carry out ecological investigations of dammed waterways. The first aim of this thesis is to evaluate whether methods for salmon and trout habitat mapping take all relevant indicators into account. LÄS MER

  5. 34. Electric alternative of hydraulic operation : Empowering safety through electrification

    Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Författare :Edvin Turesson; [2023]
    Nyckelord :Hydraulic; electrification;

    Sammanfattning : Electrification is a relevant subject in the industrial market and provides many benefits. The motivation for this project is to reduce the fire hazard by removing the hydraulic fluids from the steel mill environment. This project aims to analyze the existing hydraulic sealing unit and evaluate the electrification alternatives. LÄS MER

  7. 35. Alternative traction system for road-rail vehicles

    Master-uppsats, Lunds universitet/Innovation

    Författare :Jakob Runevad; [2023]
    Nyckelord :Product development; electric traction; construction equipment; road-rail vehicles.; Technology and Engineering;

    Sammanfattning : Excavators have traditionally been diesel driven with hydraulic actuators, but with the ongoing electrification of vehicles, smaller electric excavators are getting more common. Larger electrical excavators are still in a prototyping or early production stage but can be expected to grow. LÄS MER
