  1. 11. Digital holographic interferometry in a disturbed environment

    Författare :Henrik Lycksam; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Experimental Mechanics; Experimentell mekanik;

    Sammanfattning : Digital holographic interferometry is an optical measurement technique that is capable of measuring the movement/deformation of an object surface with extremely high accuracy, spatial resolution and temporal resolution. But, because it is very sensitive to disturbances, it is mostly used in well controlled laboratory environments. LÄS MER

  2. 12. Probabilistic design for evaluation of indoor environment

    Författare :Katarina Ljungquist; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Steel Structures; Stålbyggnad;

    Sammanfattning : In recent years indoor environment and indoor air quality has been subjected to extensive worldwide research efforts. Still, at present there are a lack of methods for prediction of risks and consequences for any defined damage to occur, similar to the probabilistic methods used in modern design codes for structures and buildings.

  3. 13. Model-Based Protocol Testing in an Erlang Environment

    Författare :Johan Blom; Bengt Jonsson; Sven-Olof Nyström; Bernhard Aichernig; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Testing; Erlang; Model-Based Testing; Symbolic Execution; Communication Protocols; Datavetenskap; Computer Science;

    Sammanfattning : Testing is the dominant technique for quality assurance of software systems. It typically consumes considerable resources in development projects, and is often performed in an ad hoc manner. This thesis is concerned with model-based testing, which is an approach to make testing more systematic and more automated. LÄS MER

  4. 14. Theoretical Considerations of Local Environment Effects in Alloys

    Författare :Tobias Marten; Igor Abrikosov; Josef Kudrnovský; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Condensed matter physics; Kondenserade materiens fysik;

    Sammanfattning : This thesis is devoted to a theoretical study of local environment effects in alloys. A fundamental property of a disordered system is that all chemically equivalent atoms are different due to their different chemical environments, in contrast to an ideal periodic solid where all the atoms that occupy equivalent positions in the crystal have exactly the same physical properties.

  5. 15. Pollen Competition as a Target for Sexual Selection in Plants

    Författare :Åsa Lankinen; Biologiska institutionen; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Sexual selection; Pollen tube growth rate; Pollen selection models; Pollen interactions; Pollen competition; Plants; Phenotypic plasticity; Non-random mating; Genotype by environment interactions; Mate choice; Viola tricolor.; Plant ecology; Växtekologi;

    Sammanfattning : According to the theory of sexual selection, traits can evolve because they confer a mating advantage in competition with members from the same sex. In animals, sexual selection is considered as an important evolutionary force. In this thesis I have investigated the potential for sexual selection in plants. LÄS MER
