1. 1. Varför gör vi inte som vi säger? : Realitet, retorik och dialektik i svensk stadsutveckling med fokus på energi och fysiska strukturer

   Författare :Tony Svensson; Göran Cars; Ulf Ranhagen; Kristina L Nilsson; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Complexity; comprehensive planning; dialectic; indicators; reality; resilience; rhetoric; urban planning; Komplexitet; översiktsplanering; dialektik; indikatorer; realitet; resiliens; retorik; fysisk planering; Planering och beslutsanalys; Planning and Decision Analysis;

   Sammanfattning : In this doctoral thesis, case-studies on comprehensive planning and urban development in two Swedish municipalities reveals explanations and answers to how urban form that affects energy use and climate has changed between 1990-2010, how visions and goals are expressed in planning documents and what might cause the gap between the rhetoric of planning and the reality of urban development concerning energy and climate issues.Several methods are used under the canopy of case study methodology and an abductive research approach; time-series analysis with GIS-indicators to measure changes in urban structure; discourse analysis with a focus on rhetoric and interviews with responsible planning officials using a range of dialectics-based concepts as a framework to reveal hidden structures and mechanisms behind the gap.

3. 2. Computational Biomechanics in Cross-country Skiing

   Författare :Joakim L. Holmberg; Anders Klarbring; Ingrid Svensson; Linköpings universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Computer simulation; Inverse dynamics; Musculoskeletal; Optimization; Simulation model; Sports; Computational Biomechanics; Cross‐country Skiing; Engineering mechanics; Teknisk mekanik;

   Sammanfattning : Traditionally, research on cross‐country skiing biomechanics is based mainly on experimental testing alone. Trying a different approach, this thesis explores the possibilities of using computational musculoskeletal biomechanics for cross‐country skiing. As far as the author knows, this has not been done before. LÄS MER

4. 3. Cobalt and Nickel Bioavailability for Biogas Formation

   Författare :Jenny Gustavsson; Bo Svensson; Anna Karlsson; Piet N.L. Lens; Linköpings universitet; []
   Nyckelord :Biogas production; bioavailability; cobalt; nickel; sequential extraction; S XANES; 454-pyrosequencing.; Biogasproduktion; biotillgänglighet; kobolt; nickel; sekventiell extraktion; S XANES; 454-pyrosekvensering;

   Sammanfattning : Supplementation of trace metals such as Co and Ni may improve anaerobic digestion of organic material for biogas formation. Which trace metals that are needed and the quantity to apply are, at least partly, related to metal speciation and bioavailability. LÄS MER

5. 4. Microstructure Formation and Mechanical Properties in Compacted Graphite Iron

   Författare :Mathias König; Ingvar L. Svensson; Magnus Wessén; Torsten Sjögren; Jönköping University; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Cast iron; CGI; Microstructure formation; Mechanical properties;

   Sammanfattning : Compacted graphite iron is rapidly becoming an attractive alternative for engine applications in the automotive industry. The improved process control now available that allows CGI components to be cast in a reproducible and reliable way has been the driving force for this development. LÄS MER

7. 5. Microstructure Formation During Solidification and Solid State Transformation in Compacted Graphite Iron

   Författare :Mathias König; Magnus Wessén; Ingvar L. Svensson; Jorge Sikora; Jönköping University; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Cast Iron; CGI; Microstructure Formation; Mechanical Properties; Modelling; Solidification; Solid State Transformation;

   Sammanfattning : Compacted graphite iron (CGI) is rapidly becoming an attractive alternative material for engine components in the automotive industry, replacing lamellar graphite iron (LGI) in applications where high mechanical strength is desired. However, the gain in mechanical strength comes with a cost; thermal conductivity, process control and machining are three areas that are more challenging for CGI. LÄS MER
