  1. 21. Some theoretical and numerical aspects of the N-body problem

    Kandidat-uppsats, Lunds universitet/Matematik (naturvetenskapliga fakulteten)

    Författare :Kjartan Kari Gardarsson Myrdal; [2013]
    Nyckelord :N-body problem; central configuration; Euler s solution; Lagrange s solution; numerical methods; Euler s method; Heun s method; the classical fourth-order Runge-Kutta scheme; Störmer-Verlet; Mathematics and Statistics;

    Sammanfattning : The N-body problem has been studied for many centuries and is still of interest in contemporary science. A lot of effort has gone into solving this problem but it's unlikely that a general solution will be found with the mathematical tools we have today. We review some of the progress that has been made over the centuries in solving it. LÄS MER

  3. 22. Dynamical Functional Particle Method applied to the Schrödinger Equation : Exact solutions of three-body exotic ions

    Master-uppsats, Institutionen för naturvetenskap, teknik och matematik

    Författare :Kristoffer Karlsson; [2012]
    Nyckelord :;

    Sammanfattning : The aim of this master thesis has been to solve the fully correlated non-relativistic Schrödinger Equation for three-particle systems by using the Dynamical Functional Particle Method (DFPM) and control the solutions by comparing with the results from the literature. The three-particle systems that has been analyzed is helium, a muon-based ion and the negative ion of positronium. LÄS MER

  4. 23. Tribological testing of drill bit inserts

    Uppsats för yrkesexamina på avancerad nivå, Tillämpad materialvetenskap

    Författare :Jakob Oskarsson; [2011]
    Nyckelord :tribological testing; drill bit inserts; cemented carbide wear;

    Sammanfattning : This thesis work sought to find a tribological testing method suitable for cementedcarbide drill bit inserts used when drilling rock. A review of the literature publishedon the matter showed that there are quite a few test methods developed for wearstudies with cemented carbides, but most of them were not designed for the rockdrilling industry.
