  1. 16. Scalar fields on star graphs

    University essay from Avdelningen för fysik och elektroteknik

    Author : Mattias Andersson; [2011]
    Keywords : quantum graphs; quantum field theory;

    Abstract :  A star graph consists of a vertex to which a set of edges are connected. Such an object can be used to, among other things, model the electromagnetic properties of quantum wires. A scalar field theory is constructed on the star graph and its properties are investigated. READ MORE

  3. 17. FE analysis of a dog clutch for trucks withall-wheel-drive

    University essay from Institutionen för teknik, TEK

    Author : Mattias Andersson; Kordian Goetz; [2010]
    Keywords : Gleason type curvic coupling; Dog clutch; All-wheel-drive; FE analysis; Klokoppling; Allhjulsdrift; FE-analys;

    Abstract : The thesis is carried out in order to improve the transfer case in trucks with all-wheel-drive. When the truck loses traction at the rear wheels, due to slippery surfaces, wheel-spin occurs. If the driver engages the all-wheel-drive at a point where traction already has been lost, a relative rotational speed in the dog clutch will occur. READ MORE

  4. 18. Yang-Baxter equations for systems with boundaries and defects

    University essay from Fakulteten för teknik- och naturvetenskap

    Author : Mattias Andersson; [2009]
    Keywords : integrable models; algebras;

    Abstract : The Yang-Baxter equation appear in various situations in physics and mathematics. For example it arises as a consistency condition in integrable models. The reflection equation (boundary Yang-Baxter equation) is a generalization of the Yang-Baxter equation to systems with a boundary. READ MORE

    Abstract : Hemp is an annual energy crop that fits very well in Swedish crop rotations. It is an interesting crop with many benefits, for example its ability to establish a large quantity of biomass in one year. Hemp is easy to grow and out-competes unwanted weeds through its aggressive growth pattern without the need for pesticides. READ MORE
