  2. 21. Simulation of bending and hydroforming : constitutive modeling and failure prediction

    Author : Mikael Jansson; Linköpings universitet; []
    Keywords : hydroforming; anisotropy; aluminium; finite element simulation; forming limits;

    Abstract : In recent years, the automotive industry has shown increased interest in reducing weight and improving environmental effects of cars. This has lead to an increased use of lightweight parts. READ MORE

  4. 22. Development of Energy-based Damage and Plasticity Models for Asphalt Concrete Mixtures

    Author : Ibrahim Onifade; Björn Birgisson; Linbing Wang; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; energy-based models; damage; X-ray computed tomography; continuum plasticity mechanics CPM; effective micro-crack stress; Transportvetenskap; Transport Science;

    Abstract : Characterizing the full range of damage and plastic behaviour of asphalt mixtures under varying strain-rates and stress states is a complex and challenging task. One reason for this  is partly due to the strain rate and temperature dependent nature of the material as well as the variation in the properties of the constituent materials that make up the composite asphalt mixture.

  5. 23. Physiotherapy in primary care for working-age patients with early back and neck pain. Screening tools, interventions and outcomes

    Author : Malin Forsbrand; Lund Ortopedi; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; back pain; neck pain; primary care; STarT Back Tool; validity; health-related quality of life; function; work ability; workplace intervention; physiotherapy interventions;

    Abstract : Patients with back and neck pain are frequently seen in primary care, where they are directed to physiotherapy as first-line treatment. The condition affects both the individual, by causing pain and disability, and society, because of high costs caused by work disability and health care consumption. READ MORE

  6. 24. Dissipative formation of galaxies in hierarchical cosmology

    Author : John Hultman; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Astronomy; merical methods; hydrodynamics; galaxies: formation; galaxies: elliptical; galaxies: structure; star formation; Astronomi; Astronomy and astrophysics; Astronomi och astrofysik; Theoretical Astrophysics; teoretisk astrofysik;

    Abstract : A description and detailed tests of a numerical code for simulations of galaxy formation is presented. The dynamics is followed with fully adaptive and Lagrangian Smooth Particle Hydrodynamics (SPH) combined with a gravitational tree method. The severe numerical problem of sub-resolution clustering is solved by merging of gas particles. READ MORE

  7. 25. An evaluation of solar powered irrigation as carbon offset projects

    Author : Alexander Olsson; Jinyue Yan; Björn Frostell; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; carbon offset; carbon sequestration; clean development mechanism; climate change adaptation; desertification; solar power water pumping; Chemical Engineering; Kemiteknik;

    Abstract : Carbon offsets have been developed as one tool to incentivise investments by developed nations in climate change mitigation activities in developing countries. The carbon offsets can be used towards the countries’ own mitigation targets but are also meant to benefit developing countries by providing a pathway to clean development. READ MORE
