  2. 16. Visible spectroscopic diagnostics : application and development in fusion plasmas

    Author : Sheena Menmuir; Professor Elisabeth Rachlew-Källne; Lorella Carraro; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; visible spectroscopy; fusion; Doppler shift; Doppler broadening; Plasma physics with fusion; Plasmafysik med fusion;

    Abstract : Diagnostic measurements play a vital role in experiments. Without them we would be in the dark with no way of knowing what was happening; of understanding the processes and behaviour occurring; or even of judging the success or failure of our experiments. The development of fusion plasma devices is no different. READ MORE

  4. 17. Thermal barrier coatings for diesel engines

    Author : Wellington Uczak de Goes; Nicolaie Markocsan; Mohit Kumar Gupta; Rogerio S. Lima; Högskolan Väst; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Thermal Barrier Coatings; Suspension Plasma Spraying; Gadolinium Zirconate; Internal Combustion Engines; Engine Efficiency; Termiska barriärbeläggningar; Plasmasprutning; Suspensionssprutning; Gadolinium; Zirkoniumdioxid; Förbränningsmotorer; Motoreffektivitet; Production Technology; Produktionsteknik;

    Abstract : The upward trend in internal combustion engine efficiency is driven by the demands for emission reduction and fossil fuel depletion. No present alternative fuel can produce energy comparable to that produced by conventional oil; this necessitates the reasonable, efficient usage of oil. READ MORE

  5. 18. External Water Condensation and Angular Solar Absorptance : Theoretical Analysis and Practical Experience of Modern Windows

    Author : Anna Werner; Arne Roos; Claes-Göran Granqvist; Svend Svendsen; Uppsala universitet; []
    Keywords : Engineering physics; Windows; External condensation; Radiative cooling; Optical properties; Coated glass; External condensation; Radiant cooling; Teknisk fysik;

    Abstract : Part I of this thesis is a theoretical background to parts II and III. Part II treats the phenomenon of decreased visibility through a glazing due to external water condensation, dew, on the external surface. Some simulations are presented where it is shown that under certain circumstances condensation can be expected. READ MORE

  6. 19. Dynamics of wood particle pyrolysis applied to gas-solids fluidisation

    Author : Ulf Sand; Rebei Bel Fdhila; Lucien Masbernat; Mälardalens högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Environmental engineering; Miljöteknik; Energi- och miljöteknik;

    Abstract : Avhandlingen behandlar matematiska modellerings- och simuleringsaspekter samt resultat rörande pyrolys av stora och små träpartiklar. Avhandlingsarbetet är inriktat på två specifika processer. Den ena är pyrolys av enstaka träpartiklar och den andra är pyrolys av fluidiserade träpartiklar. READ MORE

  7. 20. Observations of young core collapse supernova remnants

    Author : Anestis Tziamtzis; Lundqvist Peter; Sergey Zharikov; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; supernova remnants; Crab; SN 1987A; Astronomy; Astronomi; Astronomy; astronomi;

    Abstract : Studies of young remnants offer an opportunity to test theoretical models of stellar evolution, explosion models and nucleosynthesis, as well as our understanding of the compact objects in the centre of the exploded stars.The first part of the thesis involves observations of the Crab nebula.
