  1. 1. Admissible Heuristics for Automated Planning

    Författare :Patrik Haslum; Patrick Doherty; Derek Long; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; AI planning; optimal planning; temporal planning; heuristic search; Computer science; Datalogi;

    Sammanfattning : The problem of domain-independent automated planning has been a topic of research in Artificial Intelligence since the very beginnings of the field. Due to the desire not to rely on vast quantities of problem specific knowledge, the most widely adopted approach to automated planning is search. LÄS MER

  3. 2. Ventricular Long Axis Function: Amplitudes and Timings : Echocardiographic Studies in Health and Disease

    Författare :Frederick Bukachi; Anders Waldenstrom; Derek Gibson; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Medicine; Echocardiography; Doppler Tissue Imaging; Ageing; coronary disease; left ventricular function; atrial contraction; electromechanical function; coronary angioplasty.; Medicin; Dermatology and venerology; clinical genetics; internal medicine; Dermatologi och venerologi; klinisk genetik; invärtesmedicin; kardiologi; Cardiology;

    Sammanfattning : Background: The ageing process not only increases the risk of coronary artery disease (CAD) but also complicates its diagnosis and treatment. It is therefore important to understand the newer concepts of cardiovascular ageing physiology as well as methods of predicting the outcomes of therapeutic options available for the elderly with severe CAD.

  4. 3. Quantitative Trait Evolution in a Changing Environment in a Seed Beetle

    Författare :Lára R. Hallsson; Mats Björklund; Derek A. Roff; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; quantitative trait; genetic variance; environmental change; temperature; seed beetle; sexual dimorphism; plasticity; inheritance; Animal Ecology; Zooekologi;

    Sammanfattning : During the last decades the climate has been changing more rapidly than in the preceding periods. This is for instance characterized by an increase in temperature. Interestingly, such changes in the environment are not necessarily constant over time as they often show high levels of fluctuation. LÄS MER

  5. 4. Temporal and spatial trends of organohalogens in guillemot (Uria aalge) from North Western Europe

    Författare :Hrönn Jörundsdóttir; Åke Bergman; Derek Muir; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Arctic; environmental; monitoring; pollution; time trends; spatial trends; Environmental chemistry; Miljökemi; Environmental Chemistry; miljökemi;

    Sammanfattning : The Arctic and sub-Arctic region of the North Atlantic is a remote area, also in relations to environmental contaminants, such as POPs, BFRs and last but not least, PFCs. Both the BFRs and PFCs are considered emerging pollutants of significant environmental concern. LÄS MER

  7. 5. Trust in Aesthetic Testimony

    Författare :Rebecca Wallbank; Elisabeth Schellekens-Dammann; Derek Matravers; Uppsala universitet; []
    Nyckelord :Trust; aesthetic testimony; aesthetic belief; Filosofi; Philosophy;

    Sammanfattning : This thesis has two main aims. The first is to examine the kinds of circumstances in which we form new aesthetic beleifs in light of deference to aesthetic testimony. The second aim is to examine some of the implications of forming aesthetic beliefs through deference to aesthetic testimony. LÄS MER
