  1. 1. 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.

  3. 2. Punching shear in concrete flat slabs supported on slender edge steel columns

    Master-uppsats, KTH/Betongbyggnad

    Författare :Pasha Jalal; Jose Andres Perez; [2020]
    Nyckelord :Punching shear; ATENA; FEA; precast slab; flat slab; top and foot plate.; Genomstansning; ATENA; FEA; plattbärlag; pelardäck; topp- och fotplåt.;

    Sammanfattning : Punching shear is a failure mechanism caused by concentrated loads, creating a crack pattern that resembles a cone shape or piece of pie starting from the top surface of the slab and prolongs downwards. When the total shear force is greater than the shear resistance of the slab, it may eventually lead to punching shear failure. LÄS MER

  4. 3. Hökrubbor med finmaskigt hönät : skötarens arbetstid samt hästens ättid

    Kandidat-uppsats, SLU/Dept. of Anatomy, Physiology and Biochemistry

    Författare :Lisa Trillkott; Lisa Tysk; [2016]

    Sammanfattning : Evaluation of Hay Bar® with small mesh hay net – Working load and feeding time Horses are herbivores and spend 60-75 % of their day grazing when moving freely or when provided an unlimited amount of forage. Studies have shown that horses with an unlimited amount of forage choose to graze with pauses that are no longer than three to four hours. LÄS MER

  5. 4. Om portamentoanvändning för violin

    Kandidat-uppsats, Göteborgs universitet/Högskolan för scen och musik

    Författare :Zaida Ponthin; [2015-06-24]
    Nyckelord :portamento; Bruch violinkonsert; Milstein; Heifetz; Perlman; Jansen; analytiskt lyssnande; lägesväxlingar;

    Sammanfattning : I have analysed the use of portamenti by violinists Janine Jansen, Itzhak Perlman, Jascha Heifetz and Nathan Milstein in the first 8 bars and the two parallel phrases of the Max Bruch Violin Concerto No. 1 in G minor. I have copied their portamenti and recorded myself performing theese phrases in style of each violinist. LÄS MER

  7. 5. Detection of Frazil Ice at Water Intakes at Träbena Power Station

    Kandidat-uppsats, Högskolan i Skövde/Institutionen för ingenjörsvetenskap

    Författare :Iosu Carrera Artola; Alejandro Lucena Garcerán; [2014]
    Nyckelord :Frazil ice; detection; power station; hydropower; capacitor; ice; blockage; trash racks;

    Sammanfattning : Frazil ice is a phenomenon that takes place in cold regions when the water of rivers, lakes or oceans is cooled under 0ºC. Several times during winter, frazil ice can appear at river Ätran, where Träbena hydropower plant is held by the company Wetterstad Consulting AB. LÄS MER
