  2. 1. Algorithmic Bounds for Presumably Hard Combinatorial Problems

    Author : Andreas Björklund; Institutionen för datavetenskap; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; numerisk analys; system; control; Datalogi; numerical analysis; systems; Computer science; Approximation algorithms; Exact algorithms; NP-hard problems; Algorithm theory; kontroll;

    Abstract : In this thesis we present new worst case computational bounds on algorithms for some of the most well-known NP-complete and #P-complete problems and their optimization variants. We consider graph problems like Longest Path, Maximum Cut, Number of Perfect Matchings, Chromatic and Domatic Number, as well as Maximum k-Satisfiability and Set Cover. READ MORE

  4. 2. Soil compaction: effects on soil hydraulic properties and preferential water flow

    Author : Mona Mossadeghi Björklund; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Abstract : Soil compaction caused by passage of agricultural machinery over the surface is an issue in many agricultural soils with a high clay content. Compaction is known to modify soil pore structure and soil hydraulic properties, but can also affect the occurrence of preferential flow. READ MORE

  6. 4. PHYSIOLOGICAL AND BIOMECHANICAL FACTORS DETERMINING CROSS-COUNTRY SKIING PERFORMANCE

    Author : Erik Andersson; Hans-Christer Holmberg; Glenn Björklund; Thomas Stöggl; Jos J. de Koning; Mittuniversitetet; []
    Keywords : cycle characteristics; energy cost; energy yield; incline; joint angles; kinematics; kinetics; mechanics; Nordic skiing; oxygen deficit; oxygen demand; technique transitions; total metabolic rate.;

    Abstract : Cross-country (c.c.) skiing is a complex sport discipline from both physiological and biomechanical perspectives, with varying course topographies that require different proportions of the involved sub-techniques to be utilised. A relatively new event in c. READ MORE

  7. 5. Victimization, Prevalence, Health and Peritraumatic Reactions in Swedish Adolescents

    Author : Nikolas Aho; Carl Göran Svedin; Ingbeth Larsson; Marie Proczkowska Björklund; David Finkelhor; Linköpings universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Keywords: victimization; JVQ; TSCC; trauma; mediation.;

    Abstract : The aim of this thesis was to expand the knowledge of victimization in children and youth in Sweden. Victimization, prevalence, health and peritraumatic reactions were explored in a cross sectional, representative sample of 5,960 second grade high school students in Sweden. A computerized survey was developed and administered in class room setting. READ MORE
