  1. 1. Regressor and Structure Selection : Uses of ANOVA in System Identification

    Författare :Ingela Lind; Lennart Ljung; Torsten Söderström; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; System identification; Regressor selection; Analysis of variance; Nonlinear systems; Structure selection; Automatic control; Reglerteknik;

    Sammanfattning : Identification of nonlinear dynamical models of a black box nature involves both structure decisions (i.e., which regressors to use and the selection of a regressor function), and the estimation of the parameters involved. LÄS MER

  3. 2. Structure-Magnetic Relationships in the Fe-Mn-P-Si System for Energy Applications

    Författare :Viktor Höglin; Yvonne Andersson; Per Nordblad; Martin Sahlberg; Mogens Christensen; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Magnetocaloric; X-ray powder diffraction; Neutron powder diffraction; Magnetization measurements; Phase diagram; Crystal structure; Magnetic structure; Incommensurate structure; Ferromagnetic; Antiferromagnetic; Fe2P; Fe-Mn-P-Si.; Kemi med inriktning mot oorganisk kemi; Chemistry with specialization in Inorganic Chemistry;

    Sammanfattning : Demands for new, energy-efficient appliances have greatly increased in response to our growing need for a more environmentally friendly society. Magnetic refrigeration is a technique that utilizes the magnetocaloric effect, with possible energy savings of up to 30% compared to commercial gas compression refrigerators. LÄS MER

  4. 3. Essays on Capital Structure

    Sammanfattning : Chapter 2 analyses the relationship between capital structure and industry classification of Swedish firms. This study also analyses the determinants of the capital structure at the industry level. LÄS MER

  5. 4. Människa, organisation, ADB-system : Mot en människoorienterad syn på systemutveckling

    Författare :Kerstin Grundén; Dan Jonsson; Pelle Ehn; Högskolan Väst; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Human-oriented system development; organization; system development; MOA-model; MOA-perspective; Sociology; Sociologi; Sociologi; Sociology;

    Sammanfattning : The background for this thesis is the author's experience of working as a system analyst during the years 1975-1081. During this period, the system development work can be characterized as expert-oriented, very often leading to the construction of large, integrated EDP-systems. LÄS MER

  7. 5. Species interactions and community structure

    Författare :Peter Frodin; Technology and Social Change (WTS) Centre for Work; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Ecology; Ekologi; spatial structure; local stability; enrichment; species interactions; Community structure; population dynamics;

    Sammanfattning : In this theses I have focused on how the mechanisms of species interactions affect community structure. It is well known that certain species may have a particularly strong influence on the structure of a community. What is not fully understood is how to characterize these species that have such a strong impact on community structure. LÄS MER
