  1. 1. Environmental Perspectives on Urban Material Stocks used in Construction : Granular Materials

    Author : Simon Magnusson; Sven Knutsson; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Soil Mechanics; Geoteknik;

    Abstract : The peoples demand of functions and services in cities is the driver for energy and material flows. Most people in the world are now living in urban areas. In order to achieve a sustainable development of cities, both resource use and environmental impact have to be reduced. READ MORE

  2. 2. Governing Development : The Millennium Development Goals and Gender Policy Change in Sub-Saharan Africa

    Author : Helena Hede Skagerlind; Jonas Tallberg; Kristina Jönsson; Jeffrey Checkel; Mathias Koenig-Archibugi; Stockholms universitet; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Millennium Development Goals; sustainable development; gender equality; human rights; performance indicators; United Nations; Sub-Saharan Africa; Kenya; Ethiopia; economic conditionality; social influence; Political Science; statsvetenskap;

    Abstract : Recent decades have witnessed an upsurge in the use of different forms of global performance assessments as a means to influence the behavior of states. Within the area of international development, the Millennium Development Goals (MDGs) reinforced the practice of development governance through global performance indicators (GPIs) and gained considerable agenda-setting power among the international development community.

  3. 3. Development of Nanostructured Tungsten Based Composites for Energy Applications

    Author : Mazher Ahmed Yar; Mamoun Muhammed; Per-Olov Käll; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Tungsten; Nano-tungsten; ODS tungsten; W-La2O3; W-Y2O3; SPS; Plasma-facing materials; Armour material; fusion material;

    Abstract : Tungsten (W) based materials can be used in fusion reactors due to several advantages. Different fabrication routes can be applied to develop tungsten materials with intended microstructure and properties for specific application including nanostructured grades. READ MORE

  4. 4. Material Development for Electron Beam-based Powder Bed Fusion

    Author : William Sjöström; Lars-Erik Rännar; Carlos Botero; Johan Moverare; Mittuniversitetet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Additive manufacturing; Electron beam; Powder bed fusion; EBM; PBF-EB; PBF-EB M; PBF-EB C; Process development; Material development; Ti-6Al-4V; 316L; V4E; Al2O3;

    Abstract : Electron beam powder bed fusion (PBF-EB) is an additivemanufacturing (AM) method based on layer-by-layer melting of apowder bed. The technology is industrialized in certain applicationsbut still considered as immature and is not as widely used as laserbeam-based systems (PBF-LB). READ MORE

  5. 5. On failure modelling in finite element analysis : material imperfections and element erosion

    Author : Mattias Unosson; Larsgunnar Nilsson; Kjell Simonsson; Lars Olovsson; Anders Eriksson; Linköpings universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; finite element method; element erosion; material failure; material imperfections; crack-tip; Solid mechanics; Fastkroppsmekanik;

    Abstract : This dissertation concerns failure modelling with material imperfections and element erosion in finite element analyses. The aim has been to improve the element erosion technique, which is simple to use and implement and also computationally inexpensive. READ MORE
