  1. 6. Scalable Bayesian spatial analysis with Gaussian Markov random fields

    Författare :Per Sidén; Mattias Villani; Anders Eklund; Håvard Rue; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Spatial statistics; Bayesian statistics; Gaussian Markov random fields; fMRI; Machine learning; Spatial statistik; Bayesiansk statistik; Gaussiska Markov-fält; fMRI; Maskininlärning;

    Sammanfattning : Accurate statistical analysis of spatial data is important in many applications. Failing to properly account for spatial autocorrelation may often lead to false conclusions. LÄS MER

  3. 7. Adolescents at risk of persistent antisocial behaviour and alcohol problems : The role of behaviour, personality and biological factors

    Författare :Jenny M. Eklund; Britt af Klinteberg; Per-Anders Rydelius; David P. Farrington; Stockholms universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; adolescence; gender; hyperactive behaviour; biological vulnerability; personality; norm breaking behaviour; criminality; violence; alcohol problems; Psychology; Psykologi;

    Sammanfattning : Antisocial behaviour and alcohol problems are areas of great concern to society, not only associated with personal and emotional costs for the affected individuals and their victims, but also with major societal financial costs. What makes some individuals more likely than others to develop these kinds of problems? The general aim of this thesis was to explore the role of individual characteristics in the development of antisocial behaviour and alcohol problems. LÄS MER

  4. 8. Epitaxy of oxide and nitride thin films grown by magnetron sputtering

    Författare :Faezeh Alijan Farzad Lahiji; Per Eklund; Arnaud Le Febvrier; Biplab Paul; Tomas Nyberg; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : The need for electronic devices with new functionalities has caused research to move in a way to design and utilize materials with high-performance thermoelectricity, widely used in batteries, sensors, and electronic devices. Two-dimensional materials (2D) with unique structures and remarkable properties have been identified to fabricate oxide heteroepitaxy. LÄS MER

  5. 9. Nanostructured materials for gas sensing applications

    Författare :Kristina Buchholt; Per Eklund; Lars Hultman; Anita Lloyd Spetz; Harry L. Tuller; Linköpings universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP;

    Sammanfattning : In this Thesis I have investigated the use of nanostructured films as sensing and contact layers for field effect gas sensors in order to achieve high sensitivity, selectivity, and long term stability of the devices in corrosive environments at elevated temperatures. Electrochemically synthesized Pd and Au nanoparticles deposited as sensing layers on capacitive field effect devices were found to give a significant response to NOx with small, or no responses to H2, NH3, and C3H6.

  7. 10. Epitaxial growth, structure, and thermoelectric properties of CaMn- and V-based oxides

    Författare :Erik Ekström; Per Eklund; Biplab Paul; Fredrik Eriksson; Nini Pryds; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Thin film; PVD; Oxides; Epitaxy; XRD;

    Sammanfattning : This thesis is focused on physical vapor deposition, epitaxy, and structural characterization of CaMnO3 and VO2. Environmentally friendly and abundant materials are important for energy savings in applications, e.g., thermoelectrics for waste-heat recycling and thermochromic materials for passive indoor-temperature regulation.
