  2. 1. A study of electrons and phonons in metals

    Author : Göran Grimvall; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : .... READ MORE

  4. 2. Atomistic simulations of lattice defects

    Author : Mattias Forsblom; Grimvall Göran; Kai Nordlund; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Theoretical physics; Teoretisk fysik; Physics; Fysik;

    Abstract : Mechanical properties of solids are governed by crystal imperfections. Computational materials science is largely concerned with the modelling of such defects, e.g. their formation, migration, and interaction energies. READ MORE

  5. 3. Roadmap for trend detection and assessment of data quality

    Author : Karl Wahlin; Anders Grimvall; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Computer science; Datavetenskap;

    Abstract : Regular measurements of the state of the environment constitute a cornerstone of environmental management. Without the support of long time series of reliable data, we would know much less about changes that occur in the environment and their causes. READ MORE

  6. 4. Monotonic and Semiparametric Regression for the Detection of Trends in Environmental Quality Data

    Author : Mohamed Hussian; Anders Grimvall; Ali Hadi; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Normalisation; Monotonic; Semiparametric; Temporal trends; fluctuations; global; local; Matematisk statistik; Icke-parametriska metoder; Statistics; Statistik;

    Abstract : Natural fluctuations in the state of the environment can long conceal or distort important trends in the human impact on our ecosystems. Accordingly, there is increasing interest in statistical normalisation techniques that can clarify the anthropogenic effects by removing meteorologically driven fluctuations and other natural variation in time series of environmental quality data.

  7. 5. The many-electron energy in density functional theory : from exchange-correlation functional design to applied electronic structure calculations

    Author : Rickard Armiento; Göran Grimvall; Jens K. Nörskov; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Physics; Fysik;

    Abstract : Att förutsäga egenskaper hos material och kemiska system är en viktig komponent för teoretisk och teknisk utveckling i fysik, kemi och biologi. Ett systems egenskaper styrs till stor del av dess elektrontillstånd. Datorprogram som baseras på täthetsfunktionalsteori kan beskriva elektronkonfigurationer mycket noggrant. READ MORE
