1. 11. Indirect Detection of Neutralino Dark Matter

   Författare :Piero Ullio; Marc Kamionkowski; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Theoretical Physics; teoretisk fysik;

   Sammanfattning : The detection of dark matter is a primary issue in today's astrophysics. Although the lightest supersymmetric particle, generally assumed to be a neutralino, is an excellent dark matter candidate, it is not easy to prove that such particles are the main component of galactic halos.

   Sammanfattning : The current technology within combustion engines have the possibility of handling the more stringent legislative demands on combustion engines. However the required solutions are getting more expensive and technically challenging. LÄS MER

4. 13. Methods for Synchrophasor-Based Power SystemInstability Detection and HVDC Control

   Författare :Rujiroj Leelaruji; Luigi Vanfretti; Jean Mahseredjian; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Wide-Area Monitoring Protection and Control Systems; Synchrophasor applications; Wide-Area Voltage Instability Detection; Wide-Area EarlyWarning Systems; Automatic Voltage Stabilizer;

   Sammanfattning : The recent availability Phasor Measurement Unit (PMU) functionalities in relay technology has opened up new opportunities for power system protection, allowing this microprocessor-based technology to be used beyond traditional protection purposes. This technology now also considers the computation and communication mechanisms that allow the transmission of synchronized phasor measurements. LÄS MER

5. 14. Axionlike particles, quantum loops, and supernovae : The role of quantum loop corrections for astrophysical ALPs

   Författare :Eike Christoph Müller; David Marsh; Frank Wilczek; Bo Sundborg; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Theoretical Physics; teoretisk fysik;

   Sammanfattning : In this thesis the quantum field theory and astrophysical phenomenology of axionlike particles (ALPs) are studied. The effective field theory of ALPs is reviewed with a special focus on quantum loops, the renormalization group equations, and the equivalent forms of the interaction between ALPs and fermions.

7. 15. LYME BORRELIOSIS Detection and identification of the infecting genotype

   Författare :Katharina Ornstein; Sektion III; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Parasitologi människa och djur ; Parasitology human and animal ; Infektioner; Infections; PCR; genospecies; Lyme borreliosis; Borrelia burgdorferi; Microbiology; bacteriology; virology; mycology; Mikrobiologi; bakteriologi; virologi; mykologi;

   Sammanfattning : Lyme borreliosis is caused by the spirochete Borrelia burgdorferi sensu lato, a bacterium with a parasitic life-style, which is transmitted between hosts by the Ixodes tick-vector. Humans will incidentally become infected. The resulting illness can involve the skin, nervous system, joints and heart. LÄS MER
