1. 6. Drying of iron ore pellets : analysis with CFD

   Författare :Anna-Lena Ljung; Luleå tekniska universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Strömningslära; Fluid Mechanics;

   Sammanfattning : Iron ore pellets are a highly refined product and for companies such as LKAB it is important to constantly improve the pelletization in order to enhance production and improve product quality. A long term goal has been established to develop and considerably refine tools and techniques with which the drying zone of a pelletizing plant can be optimized. LÄS MER

3. 7. Multiscale modeling of atomic transport phenomena in ferritic steels

   Författare :Luca Messina; Pär Olsson; Nils Sandberg; Pål Efsing; Pascal Bellon; KTH; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; diffusion; impurities; iron; metals; kinetic Monte Carlo; ab initio; mean field; defects; embrittlement; reactor pressure vessel; neural networks; Fysik; Physics;

   Sammanfattning : Defect-driven transport of impurities plays a key role in the microstructure evolution of alloys, and has a great impact on the mechanical properties at the macroscopic scale. This phenomenon is greatly enhanced in irradiated materials because of the large amount of radiation-induced crystal defects (vacancies and interstitials). LÄS MER

4. 8. The Artisanal Perspective in Action : An Archaeology in Practice

   Författare :Katarina Botwid; Arkeologi; []
   Nyckelord :HUMANIORA; HUMANITIES; Archaeology; expertise; artisanal perspective; skill; artisanal interpretation; practice; craft; craftspersons; techniques; knowledge; situated learning; master–apprentice; artefacts; tools; imprints; fingerprints; colour; crayon; artist material; re-interpretation; evaluation; tacit knowledge; embodied knowledge; silent knowledge; silent studies; contemporary artisanship;

   Sammanfattning : In what way can an artisanal perspective and artisanal knowledge contribute to current archaeology? How can theories about skill and expertise explain and affect research on artisanal issues? These are the questions that are in focus and have been explored in the four collected papers and in the concluding article in this thesis. The author proposes an artisanal perspective from an interdisciplinary viewpoint. LÄS MER

5. 9. Tools for Evaluating Energy Efficiency of Steel Production : Lessons from Sweden and Europe

   Författare :Johannes Morfeldt; Semida Silveira; Mats Söderström; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; energy efficiency; indicators; iron and steel sector; systems analysis; energieffektivitet; indikatorer; järn- och stålsektorn; systemanalys; Energy Technology; Energiteknik;

   Sammanfattning : The European Union faces challenges related to climate change, security of energy supply, and competitiveness of European industries. Energy efficiency indicators are required for monitoring and controlling the effectiveness of policies such as the recently endorsed Energy Efficiency Directive. LÄS MER

7. 10. Facets of Fun: On the Design of Computer Augmented Entertainment Artifacts

   Författare :Sus Lundgren; Chalmers tekniska högskola; []
   Nyckelord :HUMANIORA; HUMANITIES; NATURVETENSKAP; NATURAL SCIENCES; game mechanics; animal expression transfer; Game Design Patterns; the Iron Horse; design tools; remnants; slow technology; the Forces-Clashes-Remnants model; clashes; myTHeme; Interactive entertainment artifacts; forces; the Interactive Quilt; MultiMonsterMania; The Hatchery;

   Sammanfattning : This thesis discusses the design of interactive entertaining artifacts such as computer games and computer augmented toys, games and objects. The aim has been to find and/or develop design tools i.e. LÄS MER
