  1. 1. Vortex-matter in Multi-component Superconductors

    Författare :Johan Carlström; Mats Wallin; Vladimir Krasnov; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Superconductivity;

    Sammanfattning : The topic of this thesis is vortex-physics in multi component Ginzburg- Landau models. These models describe a newly discovered class of supercon- ductors with multiple superconducting gaps, and posses many properties that set them apart from single component models. LÄS MER

  3. 2. Development and Validation of Methods for Characterization of Multi-Component Systems in Preparative LC

    Författare :Robert Arnell; Torgny Fornstedt; Andreas Seidel-Morgenstern; Uppsala universitet; []
    Nyckelord :Analytical chemistry; Liquid chromatography; Preparative LC; Chiral LC; Multi-component LC; Adsorption isotherm; Tracer-pulse method; Inverse method; Inverse method on plateaus; Peak deformations; Chiral drug-protein interactions; Analytisk kemi;

    Sammanfattning : This thesis concerns the development and validation of methods for characterization of multi-component preparative LC systems. Measurements of competitive adsorption isotherms are performed to gain detailed information about the interactions inside the chromatography column. LÄS MER

  4. 3. Reactive Sputtering of Complex Multi-component Nitride Thin Films

    Författare :Kristina von Fieant; Erik Lewin; Ulf Jansson; Jean-Francois Pierson; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : The ever-increasing demand on improvement of protective nitride thin films has led to an expansion of the research field into multi-element based materials. The work in this thesis has focused on exploring new complex, multi-component nitride thin films based on three different material systems: Al-Ge-N, Hf-Nb-Ti-V-Zr-N and Al-Cr-Nb-Y-Zr-N. LÄS MER

    Sammanfattning : .... LÄS MER

  7. 5. Optimization of Maintenance Planning for Multi-Component Systems, and Primal-Dual Convergence Characterizations in Convex Optimization

    Författare :Magnus Önnheim; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; subgradient methods; Lagrangian dual; primal recovery; inconsistent convex programs; ergodic sequences; maintenance scheduling; preventive maintenance; deterioration cost; deterioration cost;

    Sammanfattning : This thesis considers two topics within mathematical programming. The first topic is an investigation into the behaviour of primal-dual subgradient algorithms with primal ergodic averaging in the case where it is not known a priori whether the primal program is consistent or not.
