1. 1. A systems approach to ice loads on concrete dams

   Författare :Rikard Hellgren; Richard Malm; Anders Ansell; Erik Nordström; Pierre Legér; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Ice loads; Ice pressure; Dam safety; Concrete dams; Cold regions; Monitoring; Measurements; Concrete Structures; Betongbyggnad;

   Sammanfattning : Dams are mainly used for the storage of water to electricity production and irrigation, or for river regulation. Continuous work to assure a high dam safety level is a prerequisite to minimize the risk for the uncontrolled release of water. LÄS MER

3. 2. Experimental Investigation of Performance, Flow Interactions and Rotor Forcing in Axial Partial Admission Turbines

   Författare :Jens Fridh; Torsten Fransson; Björn Laumert; Jürgen Seume; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; axial turbine; partial admission; part loads; experimental investigation; turbine performance; losses; dynamic rotor forces; forced response; unsteady flow; axialturbin; partialpådrag; dellaster; reglersteg; experimentell undersökning; turbinprestanda; förluster; dynamiska krafter; rotorvibration; instationär strömning;

   Sammanfattning : The thesis comprises a collection of four papers with preceding summary and supplementary appendices. The core investigation solely is of experimental nature although reference and comparisons with numerical models will be addressed. LÄS MER

4. 3. Recovery from Acidification - Policy Oriented Dynamic Modeling

   Författare :Liisa Fransson; Institutioner vid LTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Kemiteknik och kemisk teknologi; Petrology; mineralogy; geochemistry; Petrologi; mineralogi; geokemi; Chemical technology and engineering; target loads; sea-salt episode; sulfate adsorption; SAFE; LRTAP; critical loads; integrated assessment;

   Sammanfattning : Dynamic biogeochemistry models are important tools for determining the time-scales of recovery from acidification. In the review process of the 1999 UNECE LRTAP Gothenburg protocol, results from dynamic models will probably be included when determining further reductions of acidifying emissions. LÄS MER

5. 4. Offshore renewable energy systems : Quantification of extreme loads using computational methods

   Författare :Eirini Katsidoniotaki; Malin Göteman; Alison Raby; Uppsala universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; offshore systems; wave energy; CFD; extreme events; machine learning; Bayesian experimental design; active learning; surrogate modeling;

   Sammanfattning : This Ph.D. thesis investigates the dynamic response of offshore energy systems in extreme waves. The use of offshore energy technologies, such as wave energy systems and offshore wind turbines, is crucial for transitioning to clean energy and mitigating the effects of climate change. LÄS MER

7. 5. Thermoset polymers and coatings subjected to high compressive loads

   Författare :Daniel Ståhlberg; KTH; []
   Nyckelord :;

   Sammanfattning : This study describes the mechanical response of thermosetpolymers under high compressive loads. The study is dividedinto two parts. One part is focusing on the behaviour of apowder coating when used in a clamping force joint and how theproperties varies when varying the physical structure of thecoating. LÄS MER
