1. 16. Density functional studies of EPR and NMR parameters of paramagnetic systems

   Författare :Lyudmyla G. Telyatnyk; Olav Vahtras; Martin Kaupp; KTH; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; spin-restricted DFT; restricted-unrestricted approach; EPR spin Hamiltonian parameters; NMR spin Hamiltonian parameters; Bioorganic chemistry; Bioorganisk kemi;

   Sammanfattning : Experimental methods based on the magnetic resonance phenomenon belong to the most widely used experimental techniques for investigations of molecular and electronic structure. The difficulty with such experiments, usually a proper interpretation of data obtained from high-resolution spectra, opens new challenges for pure theoretical methods. LÄS MER

3. 17. Applied estimation of piecewise constant parameters

   Författare :Soheil Salehpour; Alexander Medvedev; Luleå tekniska universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Reglerteknik; Control Engineering;

   Sammanfattning : A time-varying linear system is a realistic description of many industrial processes, and nonlinear behavior can then also be accounted for. Then, we can consider a linear system with time-varying parameters as the model uncertainty, \emph{e.g.} an AR(X) model or an affine input-output approximation. LÄS MER

4. 18. On Determination of Inventory Cost Parameters

   Författare :Peter Berling; Produktionsekonomi; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Produktionsteknik; Production technology; Transportteknik; Transport technology; Ordering cost; Shortage cost; Capital cost; Holding cost; Inventory control; Real options;

   Sammanfattning : Efficient inventory control depends on correct values of inventory cost parameters, such as holding costs, shortage/stockout costs and ordering/setup costs. However, there exists surprisingly little research concerning the size of these parameters or how they should be determined. This thesis is devoted to increasing our knowledge of these matters.

5. 19. Identification and Control of Systems Subject to Abrupt Changes

   Författare :Mille Millnert; Linköpings universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Recursive identification; adaptive control; jumping parameters; Markov regime; time varying parameters;

   Sammanfattning : Many different recursive identification methods for time varying systems have been suggested in the literature. An assumption that the variations in the system parameters are slow is common for almost all the methods. LÄS MER

7. 20. Natural fiber composites : optimization of microstructure and processing parameters

   Författare :Birgitha Nyström; Luleå tekniska universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Polymeric Composite Materials; Polymera konstruktionsmaterial;

   Sammanfattning : Natural fiber composites, (NFC) are defined in this work as a group of materials where at least the fibers originates from renewable and CO2 neutral resources. NFC consists of a polymer matrix and a natural fiber. The fibers which originate from wood or plants can replace non-renewable fibers or fillers or simply replace part of the plastic. LÄS MER
