    Abstract : This thesis consists of four manuscripts in the area of nonlinear time series econometrics on topics of testing, modeling and forecasting nonlinear common features. The aim of this thesis is to develop new econometric contributions for hypothesis testing and forecasting in thesearea.Both stationary and nonstationary time series are concerned. READ MORE

  2. 2. Gap waveguide for packaging microstrip filters & investigation of transitions from planar technologies to ridge gap waveguide

    University dissertation from Örebro : Örebro universitet

    Author : Astrid Algaba Brazalez; [2013]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; parallel plate mode; coupled line filter; microstrip circuit; packaging; Artificial magnetic conductor AMC ; perfect magnetic conductor PMC ; gap waveguide; transition.; coplanar waveguide CPW ;

    Abstract : Gap waveguide technology has proved to constitute an effective alternative for the design of microwave passive components, due to its advantages with respect to traditional planar technologies and standard waveguides. There is no requirement for conductive contact between the two different metal pieces making up a gap waveguide prototype, since one of these pieces makes use of a textured surface that eliminates any possible leakage of the field through the gap to the surface of the other metal piece above it.

  3. 3. Fluctuations of smooth linear statistics of determinantal point processes

    University dissertation from KTH Royal Institute of Technology

    Author : Lambert Gaultier; KTH.; [2016]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Matematik; Mathematics;

    Abstract : We study eigenvalues of unitary invariant random matrices and other de-terminantal point processes. Paper A investigates some generalizations ofthe Gaussian Unitary Ensemble which are motivated by the physics of freefermions. READ MORE

  5. 5. Design and synthesis of rhodium and iridium bis-η2 diolefin catalysts: : Applications in C–C bond formation and asymmetric catalysis

    University dissertation from Lund University, Faculty of Science, Department of Chemistry, Centre for Analysis and Synthesis

    Author : Michaela Melcher; Lund University.; Lunds universitet.; [2018-01]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; catalysis; transition metal; ligand design; enantioselectivity; cycloadditions;

    Abstract : This thesis deals with the design and synthesis of rhodium and iridium bis-η2 diolefin catalysts and their applications in C–C bond formation and asymmetric catalysis.More specifically, the second chapter describes the development of inter- and intramolecular (5+2) cycloadditions catalyzed by cationic iridium(I) complexes that lead to the formation of seven-membered rings in a single step.
