  2. 1. On the Fundamentals of the Engineering Design Process

    Author : Damien Motte; Innovation; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; systems theory; design theory; engineering design; product development; problem solving; creativity; machine design; maskinkonstruktion;

    Abstract : In an industrial context when the product development cycles are shortened and constraints on technical innovations are high, it is very important to provide a very efficient and effective engineering design activity. In the current engineering design literature, most methodologies are by and large based on the so-called systematic engineering design approach. READ MORE

  4. 2. A study on the Submerged Entry Nozzels (SEN) respecting clogging and decarburization

    Author : Arashk Memarpour; Pär Jönsson; Sune Jansson; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Refractory; SEN; Clogging; REM; Coating; glaze; alkaline; Refractory; ZrSi2; Graphite; Alumina; Oxidation; Al2O3-C; ZrO2-C; MgO-C; decarburization; reaction mechanism; Materials science; Teknisk materialvetenskap;

    Abstract : The submerged entry nozzle (SEN) has been used to transport the molten steel from tundish to the mould. The main purpose of the SEN usage is both to prevent oxygen and nitrogen pick-up by molten steel and to achieve the desired flow condition in the mould. READ MORE

  5. 3. Clinical aspects of childbirth-related anxiety

    Author : Katri Nieminen; Klaas Wijma; Gerhard Andersson; Elsa-Lena Ryding; Barbro Wijma; Steven J. Linton; Linköpings universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Fear of childbirth; Childbirth-related PTSD; prevalence; societal costs; Internet-based Cognitive Behaviour Therapy;

    Abstract : Background: Although giving birth is a positive experience for many, some 10% of pregnant Swedish women suffer from severe fear of childbirth (FOC), which impairs their daily functioning and poses a risk for a negative delivery experience. This thesis focuses on the mental and health-economic effects of severe FOC, and explores new treatment options for childbirth-related anxiety. READ MORE

  6. 4. The clinical relevance of vertebral fractures and low back pain in elderly men

    Author : Mehrsa Kherad; Ortopedi - klinisk och molekylär osteoporosforskning; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

    Abstract : The number of vertebral fractures has increased during the last few decades.The increase could at least partly be explained by the increasing proportion of elderly in society since these fractures are more commonly found in elderly than in young individuals. READ MORE

  7. 5. A Study of the Swirling Flow Pattern when Using TurboSwirl in the Casting Process

    Author : Haitong Bai; Mikael Ersson; Pär Jönsson; Yogeshwar Sahai; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; flow pattern; swirling flow; TurboSwirl; CFD; turbulence models; water model; flödesmönster; roterandeflöde; TurboSwirl; CFD; turbulensmodeller; vattenmodell; Metallurgical process science; Metallurgisk processvetenskap;

    Abstract : The use of a swirling flow can provide a more uniform velocity distribution and a calmer filling condition according to previous studies of both ingot and continuous casting processes of steel. However, the existing swirling flow generation methods developed in last decades all have some limitations. READ MORE
