  1. 1. Self-Normalized Sums and Directional Conclusions

    Författare :Fredrik Jonsson; Allan Gut; Josef Steinebach; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Self-normalized sums; heavy-tailedness; Student s t-statistic; distributional symmetry; exponential tilting; directional conclusions; reversal rates; multiple statistical inference; the Benjamini-Hochberg procedure;

    Sammanfattning : This thesis consists of a summary and five papers, dealing with self-normalized sums of independent, identically distributed random variables, and three-decision procedures for directional conclusions. In Paper I, we investigate a general set-up for Student's t-statistic. LÄS MER

  3. 2. Driver-centred Motion Control of Heavy Trucks

    Författare :Kristoffer K D Tagesson; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Driver behaviour; active safety; torque feedback; heavy trucks; motion coordination; steering by braking; oncoming collision; electronic stability control; active steering;

    Sammanfattning : Traffic accidents constitute one of the leading global causes of death. Deadly traffic accidents occur, even in countries that have implemented far-reaching countermeasures, at a rate that cannot be tolerated. Improved safety of heavy trucks is an important remedy, as these vehicles are involved in a large part of all fatal accidents. LÄS MER

  4. 3. Genetic structuring in natural populations - the influence of life history strategies and asymmetric migration

    Författare :Lisa Sundqvist; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Population genetics; Asymmetric migration; Genetic differentiation; Resting stages; Gene flow; Phytoplankton; Macroalgae;

    Sammanfattning : In this thesis I investigate aspects of genetic differentiation and factors influencing the structure of populations. This is done with a special focus on life histories and dispersal strategies common in the marine environment. LÄS MER

  5. 4. Eco-evolutionary processes and community patterns--- novel avenues for studying biodiversity across spatial and temporal scales

    Författare :Yun-Ting Jang; Evolutionär ekologi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Eco-evolutionary dynamics; Community diversity patterns; Spatial phylogenetic patterns; Adaptive dynamics; Elevational diversity gradients; Theoretical ecology; Simulation models; Predation; Competition;

    Sammanfattning : Understanding biodiversity patterns poses a persistent challenge due to the complex interconnections of ecological and evolutionary processes. The particular difficulty comes from the various processes influencing biodiversity patterns across different spatial scales. LÄS MER

  7. 5. Numerical stress analysis in hybrid adhesive joint with non-linear materials

    Författare :Nawres Al-Ramahi; Roberts Joffe; Janis Varna; Rickard Östlund; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Polymeric Composite Materials; Polymera kompositmaterial;

    Sammanfattning : This thesis presents systematic numerical study of stresses in the adhesive of a single-lap joint subjected to various loading scenarios (mechanical and thermal loading). The main objective of this work is to improve understanding of the main material and geometrical parameters determining performance of adhesive joint for the future analysis of failure initiation and development in these structures.
