  2. 16. An experimental investigation of flow in a Kaplan runner : steady-state and transient

    Author : Kaveh Amiri; Bjarne Børresen; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Strömningslära; Fluid Mechanics;

    Abstract : Water turbines are since some years widely used for grid stabilization purposes according to their exceptional load variation capability which gives them the ability to compensate grid fluctuations initiated by the customer’s consumption or intermittent electricity production systems such as wind and solar power. Different renewable power generation technologies can be combined in mini-grids to electrify isolated villages and extend existing grid networks. READ MORE

  4. 17. Outcome of treatment for scoliosis. A multi-disciplinary follow-up at least 20 years after surgery or brace treatment in patients with adolescent idiopathic scoliosis with comparison to a matching control group

    Author : Aina Danielsson; Göteborgs universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; scoliosis; spinal fusion; brace treatment; radiography; magnetic resonance imaging; osteoarthritis; spirometry; outcome studies; quality of life;

    Abstract : Introduction: The long term outcome of treatment for adolescent idiopathic scoliosis (AIS), with brace or surgery, has previously not been fully established.Aims: To evaluate the outcome in terms of radiological appearance, degenerative changes, pulmonary function and different aspects of health related quality of life at least twenty years after completed treatment.

  5. 18. On Peritectic Reactions and Transformations and Hot Forming of Cast Structures

    Author : Hani Nassar; Hasse Fredriksson; Rian Dippenaar; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; peritectic reactions; massive transformations; thermal analysis; Fe-base alloys; steels; growth irregularities; hot forming; compression testing; flow stress; grain size.; Metallurgical manufacturing engineering; Metallurgisk produktionsteknik; Metallurgical process engineering; Metallurgisk processteknik;

    Abstract : This thesis deals with peritectic reactions and transformations that occur during the solidification of many alloys. Peritectics are believed to be a major cause of crack-formation in many steels, thus, good knowledge of the mechanisms by which these phenomena occur is essential for preventing such defects.

  6. 19. Geometry parameterisation and response surface-based shape optimisation of aero-engine compressors

    Author : Jörgen Burman; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Strömningslära; Fluid Mechanics;

    Abstract : The main goal in jet engine design is to achieve light, compact and highly efficient systems while reducing the cost and design times. Traditionally, the design has been based on trial-and-error procedures, which count on the skills and experience of the designer to suggest design improvements. READ MORE

  7. 20. Predicting suicide attempt and suicide : the role of standardised instruments in a psychiatric cohort

    Author : Åsa Lindh; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : Aim. The aim of this thesis was to assess the role of standardised instruments in prediction of suicide attempt and suicide in patients known to have an increased risk of these outcomes, namely patients with self-harm. Method. READ MORE
