  1. 1. Introduction of UXV assets into naval fleet architectures through an MILP based fleet modelling tool

    University essay from KTH/Marina system

    Author : Sjoerd Jan Sinnema; [2021]
    Keywords : Numerical cost optimization; Naval fleet modelling; UXV integration; MILP programming; Maritime engineering; Numerisk kostnadsoptimering; flottmodellering; UXV -integration; MILP -programmering; sjöfartsteknik;

    Abstract : The problem of fleet design and fleet modelling; for decades problems regarding determining fleet sizes and optimized routing problems have formed the groundwork into the fleet design and fleet optimization for a wide range of business sectors. In most of these problems only single entities or fixed design resources are optimized for a certain route and delivery objective based on minimizing operational costs. READ MORE

  3. 2. Exact eigenstates of the Inozemtsev spin chain

    University essay from KTH/Fysik

    Author : Simon Lentz; [2021]
    Keywords : Theoretical physics; Mathematical physics; quantum mechanics; many-body problems; spin chain; Inozemtsev; Calogero-Sutherland; Teoretisk fysik; Matematisk fysik; kvantmekanik; mångpartikel problem; spinnkedjor; Inozemtsev; Calogero-Sutherland;

    Abstract : This thesis deals with the following question: are there more eigenfunctions, other than the already known eigenfunctions, of the spin chain with elliptic interactions known as the Inozemtsev spin chain? The Inozemtsev spin chain interpolates between two quantum integrable spin chains, theHeisenberg spin chain and the Haldane-Shastry spin chain. Therefore it is interesting to explore eigenfunctions of the Inozemtsev spin chain in greater detail. READ MORE

  4. 3. Numerical simulations using Lattice Boltzmann Method

    University essay from KTH/Strömningsmekanik och Teknisk Akustik

    Author : Mouadh Boubaker; [2021]
    Keywords : Computational fluid mechanics; lattice Boltzmann method; numerical simulations; Beräkningsvätskemekanik; galler Boltzmann -metoden; numeriska simuleringar;

    Abstract : The lattice Boltzmann method (LBM) is widely studied andused in the last years to replace the conventional numerical solvers forthe Navier-Stokes equations. In this work, a general introduction tofluid dynamics equations and the changes when the flow is a reactivemulti-species one will be given first. READ MORE

  5. 4. Application of Deep Q-learning for Vision Control on Atari Environments

    University essay from Lunds universitet/Beräkningsbiologi och biologisk fysik

    Author : Jim Öhman; [2021]
    Keywords : Reinforcement learning; Atari 2600; Deep Q-learning; Myopic Agents; Vision Control; Physics and Astronomy;

    Abstract : The success of Reinforcement Learning (RL) has mostly been in artificial domains, with only some successful real-world applications. One of the reasons being that most real-world domains fail to satisfy a set of assumptions of RL theory. READ MORE

  6. 5. Exploring a Two Higgs Doublet Model with a U(1) Family Symmetry and a Complex Singlet

    University essay from Lunds universitet/Institutionen för astronomi och teoretisk fysik

    Author : Michal Nowak; [2021]
    Keywords : Two Higgs Doublet Model; Complex Singlet Extension; Phenomenology; Physics Beyond the Standard Model; Branco-Grimus-Lavoura Model; Physics and Astronomy;

    Abstract : In this project a two Higgs doublet model with a complex singlet and an extra family symmetry providing a mechanism for suppression of flavor changing neutral currents is explored. The goal is to investigate the phenomenological consistency of the model using a custom software framework. READ MORE
