  2. 11. Element cycling in forest soils -modelling the effects of a changing environment

    Author : Charlotta Walse; Avdelningen för kemiteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Kemiteknik och kemisk teknologi; Chemical technology and engineering; soil moisture; decomposition; base cations; weathering; acidification; scenario analysis; Environmental technology; pollution control; Miljöteknik; kontroll av utsläpp;

    Abstract : Element cycling and nutrient supply in forest ecosystems are of vital importance for short-term productivity and for longer-term land management in terms of nutrient leaching and CO2 fixation. This thesis includes a series of studies with the objective of modelling some aspects of the effect of acidification and climate change on element cycling and nutrient supply in forest soil.

  4. 12. Domain Decomposition and Preconditioned Iterative Methods for the Helmholtz Equation

    Author : Elisabeth Larsson; Kurt Otto; Bengt Fornberg; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Helmholtz equation; domain decomposition; preconditioned iterative method; fast transforms; parallelization; Numerical Analysis; Numerisk analys;

    Abstract : New preconditioned iterative solution methods for the Helmholtz equation are constructed. To evaluate the performance of the methods, two-dimensional problems with a waveguide geometry are used as model problems. Second- and fourth-order accurate finite difference discretizations are used. READ MORE

  5. 13. Algorithms for analysis of NMR projections: Design, implementation and applications

    Author : Jonas Fredriksson; Göteborgs universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NMR; projection experiments; decomposition; algorithm; automatic;

    Abstract : With an increasing rate of protein expressions the need for fast protein characterization has become more important. Protein NMR has long been an important contributor for protein characterization; being one of a few techniques that can study proteins at atomic resolution in their native state. READ MORE
