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

    University essay from Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

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

    Abstract : 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.

  2. 2. Electric alternative of hydraulic operation : Empowering safety through electrification

    University essay from Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Author : Edvin Turesson; [2023]
    Keywords : Hydraulic; electrification;

    Abstract : 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. READ MORE

  3. 3. 2d Gauge Theories

    University essay from Uppsala universitet/Teoretisk fysik

    Author : Zhou Zheng; [2022]
    Keywords : ;

    Abstract : The Yang-Mills gauge theories play prominent role in modern high energy physics and the direct non-perturbative calculations present the main challenge in the field.Two dimensional gauge theories provide a nice playground where it is possible to carry out exact computations and at the same time some non-trivial phenomena canbe studied.

  4. 4. Electrodynamic field at spatial infinity

    University essay from KTH/Fysik

    Author : Jakob Myhrman; [2022]
    Keywords : Spatial infinity; Conformal rescaling; Minkowski space; Penrose Diagram; Einstein universe; Newman-Penrose formalism; Sigma-process; Resolution of singularities; Maxwell s equations; Cylinder at spatial infinity; Rumslig oändlighet; Konform omskalning; Minkowski rummet; Penrose Diagram; Einsteins universum; Newman-Penrose formalismen; Sigma-processen; Singularitetupplösning; Maxwells ekvationer; Cylindern vid rumslig oändlighet;

    Abstract : The treatment of spatial infinity is one of the remaining major open problems in the theory of isolated self-gravitating systems. Especially when one wants to model scattering of gravitational radiation in spacetime. In this thesis the conformal theory is used to study simple electromagnetic fields, close to spatial infinity.

  5. 5. Evaluation of the test procedure for a Rubber Balloon Soil Densitometer

    University essay from Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurser

    Author : Mohammad Minhajur Ahmed; [2021]
    Keywords : Rubber Balloon Soil Densitometer; compacted soil; density; volumetric measurement; artificial pits.;

    Abstract : A Rubber Balloon Soil Densitometer is one of the essential apparatuses in Geotechnical Engineering to measure the in-place volume of compacted soil to calculate the soil density. In 2019, some renowned institutions and organizations, Vattenfall, Luleå University of Technology, Uppsala University, Lund University, and HydroResearch AB, were involved in a research project.
