  1. 11. Selected Topics in Homogenization

    Författare :Jens Persson; Anders Holmbom; Liselott Flodén; Marianne Olsson Lindberg; Mårten Gulliksson; Peter Wall; Mittuniversitetet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; homogenization theory; H-convergence; two-scale convergence; very weak two-scale convergence; multiscale convergence; very weak multiscale convergence; evolution-multiscale convergence; very weak evolution-multiscale convergence; λ-scale convergence; non-periodic linear elliptic problems; evolution-multiscale linear parabolic problems; evolution-multiscale monotone parabolic problems; detection of scales of heterogeneity;

    Sammanfattning : The main focus of the present thesis is on the homogenization of some selected elliptic and parabolic problems. More precisely, we homogenize: non-periodic linear elliptic problems in two dimensions exhibiting a homothetic scaling property; two types of evolution-multiscale linear parabolic problems, one having two spatial and two temporal microscopic scales where the latter ones are given in terms of a two-parameter family, and one having two spatial and three temporal microscopic scales that are fixed power functions; and, finally, evolution-multiscale monotone parabolic problems with one spatial and an arbitrary number of temporal microscopic scales that are not restricted to be given in terms of power functions.

  3. 12. The Technology and Economy of Farm-Scale, High-Solids Anaerobic Digestion of Plant Biomass

    Författare :Mattias Svensson; Bioteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; farm-scale; Bioteknik; farmhouse construction; Lantbruksteknik; Biotechnology; agricultural machines; kontroll av utsläpp; Agricultural engineering; Miljöteknik; pollution control; Environmental technology; Lantbruksekonomi; straw bed priming; stratified bed digesters; nitrogen recycling; greenhouse gases; Sweden; Agricultural economics; sequential single-stage fed-batch; ley crops; sustainability; wheat straw; sugar beet tops; crop residues; high-solids; economy; Anaerobic digestion; biogas upgrading;

    Sammanfattning : Anaerobic digestion is a microbially mediated process occurring in nature in the absence of oxygen and other non-carbonaceous electron acceptors. The majority of the carbon of the organic matter degraded in the process is transformed into carbon dioxide and methane. LÄS MER

  4. 13. The technical representation of returns to scale on cost and production functions

    Författare :Lorenzo Brown; Stockholms universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES;

    Sammanfattning : The basic purpose of this work is to present a general theory of returns to scale. It is a presentation of definitions, technical representations, and theorems into which returns to scale enter. LÄS MER

  5. 14. Att forma sitt rum : fullskalemodellering i participatoriska designprocesser

    Författare :Elisabeth Dalholm Hornyánszky; Institutioner vid LTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; dwelling; work environment; user; space; language game; reflection in action; tacit knowledge; full-scale modeling; design process; design tool; participation; participatory design; case study; mock-up; Architecture; interior design; Arkitektur; inredningsarkitektur;

    Sammanfattning : Architects design work sometimes originates from a simplified view of human demands and needs, which may result in environments that do not fulfill the users requirements. This thesis refers to five different case studies where the affected users were involved in the creation of their dwellings or working environment. LÄS MER

  7. 15. Optimisation methods for solving a large-scale avionics scheduling problem

    Författare :Emil Karlsson; Elina Rönnberg; Kaj Holmberg; Simin Nadjm-Tehrani; Musliu Nysret; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Optimisation; Decomposition; Large-scale scheduling; Avionics scheduling;

    Sammanfattning : Modern computer systems in aircraft are based on an integrated modular avionic architecture. In this architecture, software applications share hardware resources on a common avionic platform. Many functions in an aircraft are controlled by software and a failure in such software can have severe consequences. LÄS MER
