  2. 1. Light shapes spaces : experience of distribution of light and visual spatial boundaries

    Author : Ulrika Wänström Lindh; Göteborgs universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; HUMANIORA; HUMANITIES; HUMANIORA; HUMANITIES; Practise-based design research; distribution of light; lighting design; architecture; enclosure; perceived dimensions; atmosphere; light zones; light topography; visual spatial boundaries; Practise-based design research; distribution of light; lighting design; architecture; enclosure; perceived dimensions; atmosphere; light zones; light topography; visual spatial boundaries;

    Abstract : Light enables us to experience space. The distribution of light is vital for spatial experience but has not been the main focus of previous research on lighting. The lighting designer’s professional knowledge is to a great extent experience-based and tacit. READ MORE

  4. 2. Computer-Assisted Proofs and Other Methods for Problems Regarding Nonlinear Differential Equations

    Author : Oswald Fogelklou; Warwick Tucker; Gunilla Kreiss; Piotr Zgliczynski; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; computer-assisted proof; numerical verification; viscous Burgers’ equation; enclosure; existence; nonlinear boundary value problems; Euler equations; inverse problem; bicubic spline; interval analysis; heat equation; fluid limit; peer-to-peer networks; fixed points; stability; global stability; Mathematics; Matematik;

    Abstract : This PhD thesis treats some problems concerning nonlinear differential equations. In the first two papers computer-assisted proofs are used. The differential equations there are rewritten as fixed point problems, and the existence of solutions are proved. READ MORE

  5. 3. Child Mortality during the Demographic Transition. A Longitudinal Analysis of a Rural Population in Southern Sweden, 1766-1894

    Author : Kent Johansson; Ekonomisk-historiska institutionen; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; nutrition; frailty; the demographic transition; Sweden; hazard regression; family effects; Scania; Barker hypothesis; Child mortality; early life conditions; enclosure; Social and economic history; Ekonomisk och social historia;

    Abstract : The great decline in mortality has had a vital impact on our societies. Life expectancy has more than doubled in the past 200 years, but no acceptable explanation has yet been given for the earlier part of the decline in mortality, even though it has attracted a very broad interdisciplinary interest.

  6. 4. Alternative electronic packaging concepts for high frequency electronics

    Author : Wolfgang Peter Siebert; Sture Petersson; Shaofang Gong; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Electrical engineering; Connector; cooling; electronic; elastomer interconnect; EMC; shielded enclosure; high frequency; PCB; PWB; reverberation chamber; seams; soldering; twisted pair cable; Elektroteknik; Electrical engineering; Elektroteknik;

    Abstract : The aim of the research work presented here, is to contribute to the adaptation of electronic packaging towards the needs of high frequency applications. As the field of electronic packaging stretches over several very different professional areas, it takes an interdisciplinary approach to optimize the technology of electronic packaging. READ MORE

  7. 5. Advances in Thermal Insulation : Vacuum Insulation Panels and Thermal Efficiency to Reduce Energy Usage in Buildings

    Author : Thomas Thorsell; Folke Björk; Mark Bomberg; Targo Kalamees; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Vacuum insulation panels; VIP; serpentine edge; thermal bridge; composite film; gas diffusion; defect dominated; holistic approach; building enclosure; integrated testing and modeling; energy equivalent; field performance; air flow; thermal insulation efficiency;

    Abstract : We are coming to realize that there is an urgent need to reduce energy usage in buildings and it has to be done in a sustainable way. This thesis focuses on the performance of the building envelope; more precisely thermal performance of walls and super insulation material in the form of vacuum insulation. READ MORE
