  1. 21. Dynamics of Magnetic Molecules under Electrical Control

    Författare :Henning Hammar; Jonas Fransson; Annica M. Black-Schaffer; Alexander Shnirman; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Molecular magnets; Spin dynamics; Non-adiabatic effects; Exchange interaction; Thermoelectricity; Fysik; Physics;

    Sammanfattning : This thesis theoretically studies the dynamics of molecular magnets under electrical control. Molecular magnets are nanoscale magnets that can, e.g., consist of single-molecules or single-atoms. LÄS MER

  4. 23. Monoaminergic modulation in spinal reflex pathways from group I afferents

    Författare :Ingela Hammar; Göteborgs universitet; []
    Nyckelord :primary afferents; spinal interneurones; ventral spinocerebellar tract neurones; noradrenaline; serotonin; cat;

    Sammanfattning : Serotonin and noradrenaline are known to play an important part in modulation of spinal neuronal networks. Group I muscle afferents mediate information on dynamic changes of muscle length and tension, and modulation of actions from these afferents could be of importance for the execution of movements.

  5. 24. A Wave Expansion Method for Aeroacoustic Propagation

    Författare :Johan Hammar; Gunilla Efraimsson; Ciarán J. O'Reilly; Wim De Roeck; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Sound propagation; Sound generation; Aeroacoustics; Aerodynamics; Computational fluid dynamics; Computational aeroacoustics; Numerical methods; Lighthill; Curle; Ffowcs Williams and Hawkings; Frequency-domain propagation; Wave expansion method.; Vehicle and Maritime Engineering; Farkostteknik;

    Sammanfattning : Although it is possible to directly solve an entire flow-acoustics problem in one computation, this approach remains prohibitively large in terms of the computational resource required for most practical applications. Aeroacoustic problems are therefore usually split into two parts; one consisting of the source computation and one of the source propagation. LÄS MER

  7. 25. Content Ontology Design Patterns: Qualities, Methods, and Tools

    Författare :Karl Hammar; Henrik Eriksson; Vladimir Tarasov; Eva Blomqvist; Harald Sack; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Ontology; Ontology Design Pattern; Quality Model; eXtreme Design; XDP; WebProtégé;

    Sammanfattning : Ontologies are formal knowledge models that describe concepts and relationships and enable data integration, information search, and reasoning. Ontology Design Patterns (ODPs) are reusable solutions intended to simplify ontology development and support the use of semantic technologies by ontology engineers. LÄS MER
