  2. 6. Vacuum insulation in buildings : Means to prolong service life

    Author : Thomas I. Thorsell; Gudni Jóhannesson; Christer Sjöström; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; vacuum insulation; thermal bridge; serpentine edge; coated film; Building engineering; Byggnadsteknik;

    Abstract : Vacuum insulation panels, VIPs, constitute a new insulation material, 6 to 8 times better than traditional insulation materials, which utilizes the positive influence vacuum has on the thermal properties of certain materials. A VIP is a composite with a flat core enclosed by an envelope preventing the core to fill with gas. READ MORE

  4. 7. Additive manufacturing of Ni-based Superalloys- an analysis of parameter and strategy driven properties in Electron Beam Melting Process

    Author : Xiaoyu Zhao; Amir Rashid; Carolin Körner; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Additive manufacturing; Electron beam melting; Super-alloys; process optimization; surface defects; subsurface defects; mechanical properties; thermal stresses; thermal deformation; Production Engineering; Industriell produktion;

    Abstract : Metal AM processes produce significantly rough surfaces as compared to wrought or machined components. Currently, the as-EBM surfaces are extremely rough and consequently, the as-built components could not be directly used as commercial products. The state-of-the-art research has focused primarily on deeply machined (DM) samples. READ MORE

  5. 8. Evaluating energy efficient buildings : Energy- and moisture performance considering future climate change

    Author : Björn Berggren; Institutionen för arkitektur och byggd miljö; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Net Zero Energy Building; passive house; thermal bridge; building envelope; energy performance; moisture performance; multi criteria decision making; climate change; climate scenarios; EN ISO 13789; EN ISO 10211;

    Abstract : One of the greatest challenges the world is facing is climate change. The need of reduction of energy use and an increased use of renewable energy in buildings constitutes important climate change mitigation measures. READ MORE

  6. 9. Bridge functions in strongly coupled plasmas : theory, simulations and applications

    Author : Federico Castello Lucco; Svetlana V. Ratynskaia; Panagiotis Tolias; Giorgio Pastore; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Teoretisk fysik; Theoretical Physics; Atomic; Subatomic and Astrophysics; Atomär fysik; subatomär fysik och astrofysik;

    Abstract : Strongly coupled or non-ideal plasmas are multi-component charged systems in which at least one species possesses an average interaction energy that is comparable or larger than its thermal energy. Non-ideal plasmas are naturally occurring in dense astrophysical objects (e.g. giant planet interiors) but also engineered in the laboratory (e. READ MORE

  7. 10. Thermal stresses in concrete structures at early ages

    Author : Mats Emborg; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Structural Engineering; Konstruktionsteknik;

    Abstract : This thesis deals with the problem of formulating constitutive models for the analysis of early-age thermal stresses in concrete due to hydration. The main features of the work are constitutive modelling of early-age concrete behaviour experimental studies to check the models and to determine material parameters application of the models to some design and construction situations.
