  1. 11. Planning for Solar Buildings in Urban Environments

    Författare :Jouri Kanters; Avdelningen för Energi och byggnadsdesign; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; architecture; design tool; design process; solar energy; urban planning; photovoltaics; solar thermal; building integration; density; net zero energy buildings; interviews; parametric studies; action research;

    Sammanfattning : Energy use in buildings accounts for a significant proportion of the total energy use in many countries. While past and current buildings have solely been energy consumers, future buildings will, besides using less energy, also need to produce (part of ) the required energy on site with renewables.

  3. 12. Patterning the Dutch Compact City

    Författare :David Chapman; Matthew Carmona; David Banister; Bartlett School of Planning University College London; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Architecture; Arkitektur;

    Sammanfattning : A major challenge to town planners in Britain is to help fulfil current and future housing need in a sustainable manner and avoid excessive development land take.This thesis therefore establishes what future development models are currently under debate and undertakes extensive research into Governments preferred option the 'Compact City'.

  4. 13. On Crack Dynamics in Brittle Heterogeneous Materials

    Författare :Jenny Carlsson; Per Isaksson; Urban Wiklund; Cecilia Persson; Ralf Denzer; Uppsala universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Engineering science with specialization in Applied Mechanics; Teknisk fysik med inriktning mot tillämpad mekanik;

    Sammanfattning : Natural variation, sub-structural features, heterogeneity and porosity make fracture modelling of wood and many other heterogeneous and cellular materials challenging. In this thesis, fracture in such complicated materials is simulated using phase field methods for fracture. LÄS MER

  5. 14. CVD solutions for new directions in SiC and GaN epitaxy

    Författare :Xun Li; Urban Forsberg; Erik Janzén; Henrik Pedersen; Sebastian Lourdudoss; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; CVD; SiC; GaN; epitaxy;

    Sammanfattning : This thesis aims to develop a chemical vapor deposition (CVD) process for the new directions in both silicon carbon (SiC) and gallium nitride (GaN) epitaxial growth. The properties of the grown epitaxial layers are investigated in detail in order to have a deep understanding. LÄS MER

  7. 15. ZrB2 Thin Films : Growth and Characterization

    Författare :Lina Tengdelius; Hans Högberg; Urban Forsberg; Gregory S. Girolami; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Zirconium diboride, ZrB2, is a ceramic material with bulk properties such as high melting point (3245 °C), high hardness (23 GPa), and low resistivity (~8 μΩcm). Thin film growth of ZrB2 using physical vapor deposition has suffered from problems with films deviating from stoichiometry and with high levels of contaminants, especially high oxygen content.
