  1. 1. Thermal modelling and evaluation of borehole heat transfer

    Författare :Saqib Javed; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; ground source heat pump; fluid temperature; borehole; short-term; thermal response test; groundwater-filled; optimization; load aggregation; simulation; recovery; step-response; long-term; ground heat exchanger; times; design; ground-coupled;

    Sammanfattning : The use of ground source heat pump systems to provide heating and cooling inbuildings has increased greatly in the last decade or so. These systems have a highpotential for energy efficiency, which has environmental and economicadvantages. LÄS MER

  3. 2. Mind off driving: Effects of cognitive load on driver glance behaviour and response times

    Författare :Emma Nilsson; Chalmers tekniska högskola; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; cognitive load; visual behaviour; lead vehicle braking; traffic safety; distraction; response times; driver behaviour; intersections;

    Sammanfattning : Introduction: Safe driving requires drivers to look at relevant information in the traffic environment and react in time in case a critical event arises. Concerns exist that cognitively loading tasks might interfere with drivers’ abilities to do this. LÄS MER

  4. 3. Thermal response tests : influence of convective flow in groundwater filled borehole heat exchanger

    Författare :Anna-Maria Gustafsson; Jeffrey D. Spitler; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Vattenteknik; Water Resources Engineering; VA-teknik; Urban Water Engineering;

    Sammanfattning : The main objective of this doctorial thesis was to investigate how thermally induced movements in the groundwater (natural convective flow) may influence the heat transport in borehole and surrounding bedrock in a groundwater filled borehole heat exchanger system. The purpose was also to determine if thermal response tests could be used to detect the convective influence and the effect on evaluated heat transfer parameters, effective bedrock thermal conductivity and borehole thermal resistance.

  5. 4. Quantitative analysis of tumor growth and response to therapy

    Författare :Esmaeil Mehrara; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; tumor; growth; response; therapy; modeling; clinical;

    Sammanfattning : Modeling the natural growth of tumors is of value for evaluation of tumor progression and optimization of treatment strategies. However, modeling tumor growth based on clinical data is hampered by the limited data available, since therapy is in general initiated as early as possible after diagnosis. LÄS MER

  7. 5. The response of model food webs to species loss : secondary extinctions and relaxation times

    Författare :Charlotte Borrvall; Richard Law; Linköpings universitet; []
    Nyckelord :;

    Sammanfattning : Current destruction and fragmentation of natural habitats is predicted to cause great future losses in biodiversity (Pimm et al. 1995; Hughes et al. 1997; Sala et al. 2000). LÄS MER
