  1. 1. Droplet Velocities in a Liquid Spray

    Författare :Andreas Cronhjort; KTH; []
    Nyckelord :Liquid spray; diesel spray; droplet velocities; droplet sizes; sprayvisualization; sliced spray; particle image velocimetry; spectrum; cepstrum; cross-correlation; auto-correlation;

    Sammanfattning : A method to look into a dense liquid spray has beenevaluated. The spray was mechanically sliced to remove theobscuring parts of it, thus gaining optical access to theinternal regions and thereby allowing for visualization ofpreviously unavailable parts of the spray. LÄS MER

  3. 2. Essays on Political Representation, Electoral Accountability and Strategic Interactions

    Sammanfattning : This thesis consists of an introduction and four self-contained essays.Essay 1 (with Matz Dahlberg and Eva Mörk) investigates political representation by exploring the relationship between citizens' preferences and the preferences of their elected representatives. LÄS MER

  4. 3. Experimental study of phase separation in Fe-Cr based alloys

    Författare :Jing Zhou; John Ågren; Joakim Odqvist; Peter Hedström; Andersson Marcus; KTH; []
    Nyckelord :Duplex stainless steels; Ferritic stainless steels; Spinodal decomposition; Phase separation; Atom probe tomography; Clustering; Radial distribution function RDF ;

    Sammanfattning : Duplex stainless steels (DSSs) are important engineering materials due to their combination of good mechanical properties and corrosion resistance. However, as a consequence of their ferrite content, DSSs are sensitive to the so-called ‘475°C embrittlement’, which is induced by phase separation, namely, the ferrite decomposed into Fe-rich ferrite (α) and Cr-rich ferrite (α'), respectively.

  5. 4. Green Finance in Real Estate, Housing Price Volatility and Rental Swaps

    Författare :Aleksandar Petreski; Andreas Stephan; Agostino Manduchi; Bertram Steininger; Jönköping University; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES;

    Sammanfattning : This thesis consists of four papers that explore several aspects of the housing market in Sweden: financing of the housing construction sector, price volatility patterns of apartment and house segments and the role of the swap rental market in access to housing and household mobility.The first paper explores the effect of a firm’s reputation of being a green bond issuer on its financing costs.

  7. 5. Classical molecular dynamics simulations of collision-induced absorption : method development and evaluation

    Författare :Wissam Fakhardji; Magnus Gustafsson; Javier Martin-Torres; Jean-Michel Hartmann; Luleå tekniska universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Applied Physics; Tillämpad fysik;

    Sammanfattning : In this thesis collision-induced absorption (CIA) coefficients are computed using molec-ular dynamics (MD) simulations. Part I is dedicated to the theoretical frame of the method, from the classical theory radiation to the derivation of an absorption coefficient. LÄS MER
