  1. 21. District heating and cooling systems transition : Evaluation of current challenges and future possibilities

    Författare :Marwan Abugabbara; Avdelningen för Installations- och klimatiseringslära; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Multi-domain modelling; Modelica; Heat pumps; 5GDHC; BLTN; Validation;

    Sammanfattning : District heating and cooling systems offer a cost-effective and secure supply of heating and cooling to connected buildings. They are widely recognised as a key solution to decarbonise the building sector due to their high potential of integrating renewable energy sources. LÄS MER

  3. 22. Coping strategies and health-related quality of life in persons with traumatic spinal cord lesion

    Författare :Magnus Lundgren Elfström; Göteborgs universitet; []
    Nyckelord :spinal cord injuries; scale development; coping behaviour; distress; mental health; quality of life; psychometrics; validation; cross-sectional;

    Sammanfattning : Aims: The overall aims of the thesis were to investigate coping strategies employed by persons with traumatic spinal cord lesion (SCL) to cope with the lesion and its consequences, and to study the relations between coping strategies and health-related quality of life (HRQL). Further, specific contributions to SCL-related scale development were given. LÄS MER

  4. 23. Validation of heavy vehicle loading responses and temperature predictions in flexible pavements using field data

    Författare :Denis Saliko; Sigurdur Erlingsson; Abubeker Ahmed; Denis Jelagin; Inge Hoff; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Flexible pavements; Long heavy vehicles; Instrumented test section; Field validation; Non-destructive testing; Temperature modelling; Flexibla vägkonstruktioner; Tung trafikbelastning; Instrumenterade teststräckor; Fältvalidering; Oförstörande provning; Termisk modellering; Building Materials; Byggnadsmaterial;

    Sammanfattning : It is well established that both traffic-related loading and environmental conditions influence the structural behaviour of pavements. Pavement design methods aim to consider the effect of traffic loading and environmental variables on pavement structure, foresee their changes during the lifetime of the pavement and predict the resulting distresses and pavement life.

  7. 25. A statistical approach to multi-input equivalent fatigue loads for the durability of automotive structures

    Författare :Gwenaelle Genet; Göteborgs universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Equivalent fatigue; uniaxial and multiaxial high cycle fatigue; multi-input variable amplitude loads; rainflow counting; Morel s model; Basquin s model; Gaussian process; Markov chain; Markov chain;

    Sammanfattning : In the automotive industry, due to temporal and financial constraints, we need to strongly reduce the duration of the design phase, but still ensure reliability and robustness. Structures in service are often exposed to complex variable amplitude loads. LÄS MER
