1. 11. Real-Time Search in Large Networks and Clouds

   Författare :Misbah Uddin; Rolf Stadler; Raouf Boutaba; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Sammanfattning : Networked systems, such as telecom networks and cloud infrastructures, hold and generate vast amounts of conguration and operational data, only a small portion of which is used today by management applications. The overall goal of this work is to make all this data available through a real-time search process named network search , where queries are invoked, without giving the location or the format of the data, similar to web search.

3. 12. Search for Supersymmetry with DELPHI, and preparation for ATLAS

   Författare :Per Johansson; Kerstin Jon-And; Klas Hultqvist; Anna Lipniacka; Ritva Kinnunen; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; supersymmetry; particle physics; Elementary particle physics; Elementarpartikelfysik;

   Sammanfattning : This thesis reports on searches for supersymmetric particles, in particular neutralinos, conducted with the DELPHI detector at the LEP accelerator at CERN. The searches were performed within the framework of the Minimal Supersymmetric Standard Model (MSSM), with R-parity conserved and gravity mediated supersymmetry breaking. LÄS MER

4. 13. Color Centers in Semiconductors for Quantum Applications : A High-Throughput Search of Point Defects in SiC

   Författare :Joel Davidsson; Igor A. Abrikosov; Rickard Armiento; Viktor Ivády; Giulia Galli; Linköpings universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; point defects; color centers; high-throughput; photoluminescence; zero phonon line; SiC;

   Sammanfattning : Point defects in semiconductors have been and will continue to be relevant for applications. Shallow defects realize transistors, which power the modern age of information, and in the not-too-distant future, deep-level defects could provide the foundation for a revolution in quantum information processing.

5. 14. Search for lensed supernovae behind the galaxy cluster Abell 1689

   Författare :Tanja Petrushevska; Rahman Amanullah; Ariel Goobar; Peter Lundqvist; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; lensed supernovae; gravitational lensing; galaxy cluster Abell 1689; Astronomy; astronomi; fysik; Physics;

   Sammanfattning : Distant supernovae probe the history of cosmic expansion and star formation, and provide important information on their progenitor models. Investigation of supernovae type Ia for  are needed to reveal any evolution in their intrinsic properties, and thus their utility as existing distance indicators. LÄS MER

7. 15. Bright Needles in a Haystack : A Search for Magnetic Monopoles Using the IceCube Neutrino Observatory

   Författare :Alexander Burgman; Carlos Pérez de los Heros; Olga Botner; Allan Hallgren; David Milstead; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; magnetic monopole; IceCube; astroparticle physics; neutrino telescope; Fysik med inriktning mot elementarpartikelfysik; Physics with specialization in Elementary Particle Physics;

   Sammanfattning : The IceCube Neutrino Observatory at the geographic South Pole is designed to detect the light produced by the daughter-particles of in-ice neutrino-nucleon interactions, using one cubic kilometer of ice instrumented with more than 5000 optical sensors.Magnetic monopoles are hypothetical particles with non-zero magnetic charge, predicted to exist in many extensions of the Standard Model of particle physics.
