1. 6. Getting it Together: A Genre Analysis of the Rhetorical Structure of Open University Television Programmes in Science and Technology

   Författare :Rowena Jansson; Engelska; []
   Nyckelord :HUMANIORA; HUMANITIES; English language and literature; distance learning.; television teaching; metadiscourse; transition; episode; rhetorical structure; Genre analysis; discourse analysis; Engelska språk och litteratur ;

   Sammanfattning : This thesis is concerned with uncovering the organisational structure underpinning Open University television programmes in scientific and technological fields. Using a genre analysis which takes into account the unique contextual configuration in which vision and pedagogical purpose play a vital part a rhetorical structure is revealed. LÄS MER

3. 7. On stability, transition and turbulence in three-dimensional boundary-layer flows

   Författare :Seyed Mohammd Hosseini; Ardeshir Hanifi; Spencer Sherwin; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Receptivity; stability; optimal growth; three-dimensional bound- ary layers; crossflow instability; roughness control; freestream turbulence; sec- ondary instability; transition; turbulence;

   Sammanfattning : A lot has changed since that day on December 17, 1903 when the Wright brothers made the first powered manned flight. Even though the concepts behind flying are unaltered, appearance of stat-of-the-art modern aircrafts has undergone a massive evolution. LÄS MER

4. 8. Energy consumption transition : final household energy consumption in the case of Sweden 1920-2010

   Författare :Mikael Levin; Lars-Fredrik Andersson; Ann-Kristin Bergquist; Thomas Pettersson; Bengt Kriström; Umeå universitet; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; economic history; households; energy transition; energy consumption; residential; electrical appliances; Carbon dioxide; emission; ekonomisk historia; Economic History;

   Sammanfattning : This licentiate thesis examines households’ final energy consumption over the long run by measuring their final energy use and examining how structural, institutional and economic factors affected the demand for energy in the residential sector during the period 1920-2010, a period covering the transition from traditional to fossil to renewable energy carriers. I believe that wider understanding of the historical energy transition and energy consumption within the residential sector might help us gain important insights into the long-run development and the factors affecting energy consumption among the households.

5. 9. Bayesian Cluster Analysis : Some Extensions to Non-standard Situations

   Författare :Jessica Franzén; Daniel Thorburn; Jukka Corander; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Cluster analysis; Clustering; Classification; Mixture model; Gaussian; Bayesian inference; MCMC; Gibbs sampler; Deviant group; Longitudinal; Missing data; Multiple imputation; Statistics; Statistik; Statistics; statistik;

   Sammanfattning : The Bayesian approach to cluster analysis is presented. We assume that all data stem from a finite mixture model, where each component corresponds to one cluster and is given by a multivariate normal distribution with unknown mean and variance. LÄS MER

7. 10. Global stability analysis of three-dimensional boundary layer flows

   Författare :Mattias Brynjell-Rahkola; Dan Henningson; Philipp Schlatter; Ardeshir Hanifi; Spencer Sherwin; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Hydrodynamic stability; transition to turbulence; global analysis; boundary layers; roughness; laminar flow control; Stokes Laplace preconditioner; optimal forcing; crossflow vortices; Ginzburg-Landau; Falkner-Skan-Cooke; Blasius; lid-driven cavity;

   Sammanfattning : This thesis considers the stability and transition of incompressible boundary layers. In particular, the Falkner–Skan–Cooke boundary layer subject to a cylindrical surface roughness, and the Blasius boundary layer with applied localized suction are investigated. LÄS MER
