  1. 11. Gifting Technologies : Ethnographic Studies of End-users and Social Media Sharing

    Författare :Jörgen Skågeby; Vivian Vimarlund; Malin Sveningsson; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Sociala medier; virtuell etnografi; fildelning; gåvor; Computer science; Datavetenskap;

    Sammanfattning : This thesis explores what dimensions that can be used to describe and compare the sociotechnical practice of content contribution in online sharing networks. Data was collected through online ethnographical methods, focusing on end-users in three large media sharing networks. LÄS MER

  3. 12. Characterisation of anisotropic acoustic properties of porous materials - inverse estimation of static flow resistivity

    Författare :Christophe Van der Kelen; Peter Göransson; Nicolas Dauchez; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Vehicle engineering; Farkostteknik; Acoustics; Akustik;

    Sammanfattning : The production processes of porous materials introduce an inherent geometric anisotropy in the material at micro scale, which influences the material properties at macro scale. In this thesis, the focus is turned to one of these macroscopic properties, the flow resistivity, which is a measure of the resistance felt by the sound pressure waves as they propagate through a porous space.

  4. 13. Scribo ergo sum : Aspectos existenciales en tres novelas tardías de Carmen Martín Gaite

    Författare :Ingrid Lindström Leo; Magnus Röhl; Eva Löfquist; Stockholms universitet; []
    Nyckelord :HUMANIORA; HUMANITIES; narrative identity; memory; freedom; responsibility; authenticity; subjectivity; self-knowledge; communication; search for truth; Spanish language; Spanska språket; Spanish; spanska;

    Sammanfattning : This dissertation examines three of Carmen Martín Gaite’s later novels, identifying existential issues that are presented through the narrative. It aims to unravel issues pertaining to personal identity, freedom, communication and ethical stances in a postmodern context. The thesis is divided into three studies, one for each novel examined.

  5. 14. Nematic Liquid Crystal Spatial Light Modulators for Laser Beam Steering

    Författare :Emil Hällstig; Mikael Lindgren; Lars Sjöqvist; William Crossland; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Physics; spatial light modulator; liquid crystal; beam steering; tracking; phase modulation; fringing field; director distribution; finite-difference time-domain; polarization; temporal properties; Fysik; Physics; Fysik;

    Sammanfattning : Laser beam control is important in many applications. Phase modulating spatial light modulators (SLMs) can be used to electronically alter the phase distribution of an optical wave-front and thus change the direction and shape of a laser beam. LÄS MER

  7. 15. Correlations in Frustrated Magnets : Classical and Quantum Aspects

    Författare :Sergei Isakov; Anders Karlhede; Frederic Mila; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Physics; Fysik;

    Sammanfattning : In this thesis, we study three different aspects of the physics of frustrated magnets. First, we study the interplay of thermal and quantum fluctuations in the transverse field frustrated Ising model on the triangular lattice. LÄS MER
