  1. 1. Styrning av tågtrafik på Malmbanan

    Författare :Kristina Nilsson; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Industriell logistik; Industrial Logistics;

    Sammanfattning : The single-track Swedish iron ore line Malmbanan stretches from Luleå to the Norwegian city of Narvik. The mine company LKAB transport iron ore on Malmbanan from the mines in Kiruna and Malmberget to the harbours in Narvik and Luleå for export. The daily traffic also consists of passenger trains and freight trains. LÄS MER

  3. 2. Optimized Pacing Strategies in Cross-Country Skiing and Time-Trial Road Cycling

    Författare :David Sundström; Mats Tinnsten; Peter Carlsson; John Rasmussen; Mittuniversitetet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Optimization; numerical simulation; equations of motion; MMA; cross-country skiing; cycling; Optimering; numerisk simulering; rörelseekvationer; MMA; längdskidåkning; cykling;

    Sammanfattning : This thesis is devoted to the analysis and optimization of pacing strategies in cross-country skiing and time-trial road cycling. In locomotive sports, it is well known that variable pacing strategies using changes in the distribution of power output are beneficial when external forces vary along the way. LÄS MER

  4. 3. Dynamics of Smooth Hyperbolic Systems with Singularities

    Författare :Tomas Persson; Dynamiska system; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Matematik; Mathematics; Dimension Theory; Hyperbolic Dynamics; Subshift; SRB-measure;

    Sammanfattning : This thesis is about dynamics of piecewise hyperbolic maps on bounded sets in the plane and on the interval. It is based on the following papers: T. Persson, A piecewise hyperbolic map with absolutely continuous invariant measure, Dynamical Systems: An International Journal, 21:3 (2006), 363--378 T. LÄS MER

  5. 4. Numerical optimization of pacing strategies in locomotive endurance sports

    Författare :David Sundström; Mats Tinnsten; Peter Carlsson; Mikael Bäckström; Erik Bruun Simonsen; Mittuniversitetet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Pacing strategy; optimization; numerical simulation; equations of motion; method of moving asymptotes; cross-country skiing; cycling; Farthållningsstrategi; optimering; numerisk simulering; rörelseekvationer; method of moving asymptotes; längdskidåkning; cykling;

    Sammanfattning : This thesis is devoted to the optimization of pacing strategies in two locomotive endurance sports; cross-country skiing and road cycling. It has been established that constant pace and variable power distributions are optimal if purely mechanical aspects of locomotion are considered in these sports. LÄS MER

  7. 5. Sensitivity and selectivity studies in capillary electrophoresis

    Författare :Maria Petersson; Centrum för analys och syntes; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; peptides; dansyl amino acids; imaging detection; cyclodextrins; enantiomer separation; acoustic levitation; solid-phase extraction; preconcentration; capillary electrophoresis; micellar electrokinetic chromatography; drugs; Analytical chemistry; Analytisk kemi;

    Sammanfattning : Capillary electrophoresis is characterised by high separation efficiency, applicability to a wide range of compounds, small sample and solvent consumption and simple instrumentation. To improve sensitivity using on-line absorbance detectors, which are hampered by the short optical path length, sample volumes in the microlitre range were concentrated to nanolitre volumes either off-line or on-line.
