1. 21. Glass Transition Dynamics in Soft Condensed Matter

   Författare :Johan Mattsson; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; polymer films; beta relaxation; hydrogen bond; glass transition; polymer dynamics; cooperativity; confinement; IXS; Brillouin light scattering; excess wing;

   Sammanfattning : Materials of very different character, ranging from polymers to metals can be made into glasses. The structural and dynamical properties of glass-forming materials are fundamentally different from those found in crystals. Hence, glassy materials exhibit unique characteristics, which make them suitable for a wide range of applications. LÄS MER

3. 22. Gamma-Ray Emission from Galaxy Clusters : DARK MATTER AND COSMIC-RAYS

   Författare :Anders Pinzke; Lars Bergström; Olaf Reimer; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Galaxy clusters; gamma-rays; cosmic-rays; dark matter; High energy astrophysics; Högenergiastrofysik; teoretisk fysik; Theoretical Physics;

   Sammanfattning : The quest for the first detection of a galaxy cluster in the high energy gamma-ray regime is ongoing, and even though clusters are observed in several other wave-bands, there is still no firm detection in gamma-rays. To complement the observational efforts we estimate the gamma-ray contributions from both annihilating dark matter and cosmic-ray (CR) proton as well as CR electron induced emission. LÄS MER

4. 23. Dynamics of particles in fluids: effects of correlations and interactions

   Författare :Anshuman Dubey; Göteborgs universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; particle-laden flows; turbulent aerosols; collisions; charged droplets; hydrodynamic interactions;

   Sammanfattning : Particles suspended in turbulent fluid flows are common in Nature and in technological applications. In some cases, the relative dynamics of spherical particles may be of interest. One example is small rain droplets in turbulent clouds. The dynamics of nearby droplets is correlated because they experience a correlated airflow. LÄS MER

5. 24. Constellation Shaping in Optical Communication Systems

   Författare :Ali Mirani; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; coherent receiver; constellation shaping; multidimensional modulation format; optical communications; probabilistic shaping; geometric shaping;

   Sammanfattning : Exploiting the full-dimensional capacity of coherent optical communication systems is needed to overcome the increasing bandwidth demands of the future Internet. To achieve capacity, both coding and shaping gains are required, and they are, in principle, independent. LÄS MER

7. 25. JO-ämbetet : en offentligrättslig studie

   Författare :Jesper Ekroth; Börje Leidhammar; Stockholms universitet; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Riksdagens ombudsmän; Processrätt; Sverige; Legal Science; rättsvetenskap;

   Sammanfattning : This dissertation is written in the field of public law and examines the Swedish Office of the Parliamentary Ombudsman (OPO). The work examines the legal regime governing the OPO as well as the provisions directly relevant to the functions of that office. LÄS MER
