  1. 1. Large Eddy Simulation of Non-Local Turbulence and Integral Measures of Atmospheric Boundary Layers

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Igor Esau; Uppsala universitet.; [2003]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Meteorology; Planetary boundary layers; large eddy simulations; non-local turbulence; Meteorologi; NATURAL SCIENCES Earth sciences Atmosphere and hydrosphere sciences Meteorology; NATURVETENSKAP Geovetenskap Atmosfärs- och hydrosfärsvetenskap Meteorologi; Meteorology; meteorologi;

    Abstract : A new large eddy simulation (LES) code is developed and used to investigate non-local features of turbulent planetary boundary layers (PBLs). The LES code is based on filtered Navier-Stokes equations, which describe motions of incompressible, Boussinesq fluid at high Reynolds numbers. READ MORE

  2. 2. On the Relations between Driving Patterns, Exhaust Emissions and Network Characteristics in Urban Driving

    University dissertation from Department of Technology and Society, Lund University

    Author : Lena Smidfelt-Rosqvist; [2003]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; traffic calming; intersections; driving adaptation; speed limits; Road transport technology; driving behaviour; Vägtransportteknik; overall effects; trip-long; non-local effects;

    Abstract : The planning and design of street networks in cities influence driving behaviour and give rise to variations in driving patterns (i.e., speed and acceleration profiles) that affect exhaust emissions and fuel consumption. READ MORE

  3. 3. Modelling Damage Evolution and Fracture of Paper Materials

    University dissertation from Division of Solid Mechanics

    Author : Rickard Hägglund; [2009]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Paper material; Fracture mechanics; Tensile strength; Fibre network; Continuum damage mechanics; Non-local theory;

    Abstract : This thesis contains six papers dealing with different aspects of damage and fracture in paper. The work addresses the problem of material length scales in the context of deformation and fracture of paper materials. READ MORE

  4. 4. Modeling framework for ageing of low alloy steel

    University dissertation from KTH Royal Institute of Technology

    Author : Magnus Boåsen; KTH.; [2019]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Low alloy steel; length scale effects; size effects; plasticity; cleavage fracture; brittle fracture; weakest link; ageing; weld metal; Solid Mechanics; Hållfasthetslära;

    Abstract : Ageing of low alloy steel in nuclear applications commonly takes the form as a hardening and an embrittlement of the material. This is due to the evolution of the microstructure during irradiation and at purely thermal conditions, as a combination or separate. READ MORE

  5. 5. Transport effects in hybrid circuit QED structures

    University dissertation from Department of Physics, Lund University

    Author : Christian Bergenfeldt; [2014]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Fysicumarkivet A:2014:Bergenfeldt;

    Abstract : This dissertation deals with the electron-photon interplay in hybrid circuit QED structures. The aim is to provide a framework in which this interplay can be understood and to predict experimentally measurable transport effects. In addition an application of this interplay is proposed.
