1. 16. Field Measurements and Predictions of River Flow, Sediment Transport and Morphological Changes

   Författare :Qiancheng Xie; Staffan Lundström; James Yang; J. Gunnar I. Hellström; Anders G. Andersson; Nils Ruther; Luleå tekniska universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Alluvial river; Sediment transport; Morphological change; Meandering; Confluence-diffluence; River training; Field measurements; Numerical simulations; Physical model tests; Machine learning; Alluvial flod; Sedimenttransport; Morfologisk förändring; Slingrande; Konfluens-diffluens; Flodträning; Fältmätningar; Numeriska simuleringar; Fysiska modellprov; Maskininlärning; Strömningslära; Fluid Mechanics;

   Sammanfattning : In an alluvial lowland river, sediment is transported in the form of suspended and bed loads. The fluvial process is the macroscopic view and long-term consequence of sediment movement. LÄS MER

3. 17. Field Measurements and Numerical Simulations of Sediment Transport in a Tidal River

   Författare :Qiancheng Xie; Staffan Lundström; J. Gunnar I. Hellström; Anders G. Andersson; Nils Ruther; Luleå tekniska universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Strömningslära; Fluid Mechanics;

   Sammanfattning : In a coastal area, an alluvial lowland river has a free connection with the open sea and its flow is bidirectional. The river basin is often highly urbanized since it hosts valuable ecosystems and natural resources. Along with the growing population, climate change and human activities (e.g. LÄS MER

4. 18. Expressions of shared interpretations - Intangible outcomes of continuous quality improvement efforts in health- and elderly care

   Författare :Annika Nordin; Boel Andersson-Gäre; Ann-Christine Andersson; Bill Lucas; Jönköping University; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Continuous quality improvement; Improvement science; Outcomes;

   Sammanfattning : This thesis is anchored in improvement science, the research field of improvement. Improvement science describes and explores improvement in real-life contexts and “system of profound knowledge” (Deming, 2000) is a cornerstone. LÄS MER

5. 19. Laser Based Flow Measurements to Evaluate Hydraulic Conditions for Migrating Fish and Benthic Fauna

   Författare :S M Sayeed Bin Asad; Staffan Lundström; J. Gunnar I. Hellström; Anders G. Andersson; Berhanu Mulu Geberkiden; Luleå tekniska universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Fish Migration; Step Cylinder; Shedding; Vortex Street; Shear stress; PIV; benthic fauna; river; stones; Strömningslära; Fluid Mechanics;

   Sammanfattning : Hydropower is one of the main sources for Sweden’s energy, which is clean and renewable. It is a clean energy source because no fuels are burned which does not pollute the air and it is a renewable energy source as it only uses natural water cycle for generating energy. LÄS MER

7. 20. Hydraulic Modelling of Hydropeaking in Regulated Rivers

   Författare :Anton Burman; J. Gunnar I. Hellström; Anders G. Andersson; Ana Margarida Ferreira Teixeira da Silva; Luleå tekniska universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Strömningslära; Fluid Mechanics;

   Sammanfattning : The role of hydropower is expected to change in the close future in the Nordic countries. In order to fulfill targets set by the Paris agreement, the reliance on low emission intermittent power production such as solar and wind power is likely to increase. LÄS MER
