  1. 1. The effect of flowing water on turbine rotor vibrations

    Författare :Ida Jansson; Jörgen Burman; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Strömningslära; Fluid Mechanics;

    Sammanfattning : There is a lack of standardized rules on how the fluid in the turbine should be included in rotor models of hydraulic machinery. This thesis is an attempt to shed some light on this issue. We approach the problem from two viewpoints, situated at place at a hydropower plant and by mathematical analysis. LÄS MER

  3. 2. Vibrant bodies of swirling flow : On the limits of mechanical power transformation

    Författare :Ida Jansson; Don-Hyun Kim; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Strömningslära; Fluid Mechanics;

    Sammanfattning : This thesis pinpoints the intertwined nature of inertia. A vibrant body of a swirling flow is neither just a flow nor a body. It is both. LÄS MER

  4. 3. Cognitive work analysis in practice : Adaptation to project scope and industrial context

    Författare :Ida Bodin; Anders Jansson; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Datavetenskap med inriktning mot människa-datorinteraktion; Computer Science with specialization in Human-Computer Interaction;

    Sammanfattning : The Cognitive Work Analysis (CWA) framework is widely used by researchers for the analysis of complex systems. It, however, lacks the same impact amongst industrial practitioners. This thesis investigates possible adaptations of the framework to project and industrial constraints, and the consequences associated with such adaptations. LÄS MER

  5. 4. Inflammation in asthma: relation to symptomatology, exacerbations and lung function

    Författare :Ida Mogensen; Andrei Malinovschi; Christer Jansson; Mona Bafadhel; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Asthma; eosinophil; eosinophil cationic protein; eosinophil derived neurotoxin; periostin; neutrophil; fixed airflow obstruction; lung function; asthma attack; asthma symptom;

    Sammanfattning : Asthma is an inflammatory disease in the airways. It is characterized by respiratory symptoms such as wheezing, variable airflow obstruction and impaired lung function development. A better understanding of the underlying inflammation is crucial in order to treat and prevent asthma symptoms and lung function deterioration. LÄS MER

  7. 5. Aiming at Moving Targets : Applying Cognitive Work Analysis to Work Domains in Transition

    Författare :Ida Löscher; Anders Arweström Jansson; Åsa Cajander; Camilla Fröjd; Stas Krupenia; Catherine Burns; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; cognitive work analysis; work domain analysis; control task analysis; strategies analysis; abstraction hierarchy; contextual activity template; activity prioritization; systems design; heavy vehicle development; long haul trucks; intensive care; nursing; digitalization.; Computer Science with specialization in Human-Computer Interaction; Datavetenskap med inriktning mot människa-datorinteraktion;

    Sammanfattning : The design of IT systems for complex work environments is essential for workers to be able to operate more effectively and efficiently. To design a system that supports the workers' specific tasks we need to understand the work demands and the context in which the system operates. LÄS MER
