  2. 1. Modelling of fracture toughness using peridynamics : A Study of J-integral, essential work and homogenisation

    Author : Christer Stenström; Pär Jonsén; Kjell Eriksson; Ugo Galvanetto; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Peridynamics; J-integral; Essential work of fracture; Nonlocal methods; Meshless; Meshfree; Fracture; Crack tip; Exact analytical; Center cracked tension; Double edge notched tensile; fracture toughness; Peridynamik; Brottmekanik; Sprickspets; Brottseghet; Spänningsintensitet; Hållfasthetslära; Solid Mechanics;

    Abstract : Fracture toughness is one of the most important properties of a material. Being able toaccurately estimate the energy that goes into forming new crack surfaces is essential for the development of new materials, quality assurance, structural monitoring and failure analysis. READ MORE

  5. 3. Maximal Unitarity at Two Loops : A New Method for Computing Two-Loop Scattering Amplitudes

    Author : Kasper J. Larsen; Lisa Freyhult; David Kosower; Joseph Minahan; Paul Heslop; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Amplitudes; NNLO calculations; Quantum Chromodynamics; Unitarity; Fysik med inriktning mot elementarpartikelfysik; Physics with specialization in Elementary Particle Physics;

    Abstract : The study of scattering amplitudes beyond one loop is necessary for precision phenomenology for the Large Hadron Collider and may also provide deeper insights into the theoretical foundations of quantum field theory. In this thesis we develop a new method for computing two-loop amplitudes, based on unitarity rather than Feynman diagrams. READ MORE

  6. 4. Time-Series Econometrics Applied to Macroeconomic Issues

    Author : Abdulnasser Hatemi-J; Jönköping University; []
    Keywords : ;

    Abstract : This doctoral dissertation is a collection of six articles. Special attention is paid to model specification and the time-series properties of the data applied in each case. The first two articles deal with fiscal policy in Sweden and the effects of EMU criteria convergence. READ MORE

  7. 5. The roles of inner nuclear membrane proteins during interphase and mitosis

    Author : Veronica J. Larsson; Einar Hallberg; Neus Visa; Stockholms universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Samp1; mitotic spindle; centrosome; LINC complex; Lamina; Sun1; mitosis; neurokemi med molekylär neurobiologi; Neurochemistry with Molecular Neurobiology;

    Abstract : The nuclear envelope (NE) consists of two concentric membranes, the outer nuclear membrane (ONM) and the inner nuclear membrane (INM). The LINC (linker of nucleoskeleton and cytoskeleton) complex spans both the ONM and the INM connecting the cytoskeleton to the nucleoskeleton and chromatin. READ MORE
