1. 26. Trees, Queues and Alcohols

   Författare :Per Sillrén; Chalmers tekniska högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Raman Scattering; Neutron Diffraction; Alcohols; EPSR; Quasi Elastic Neutron Scattering; Neutron Spin Echo; Monte Carlo Simulation; Hydrogen Bonded Liquids;

   Sammanfattning : Hydrogen bonded (H-bonded) materials, such as water, alcohols, sugars, and even DNA, are extremely important for biology, as well as chemical industry. Alcohols are used as solvents in paints, in perfumes, as cleaners, anti-freezers, or as an alternative to petrol in combustion engines. LÄS MER

3. 27. Accelerators for Physics Experiments : From Diagnostics and Control to Design

   Författare :Elena Wildner; Thomas Lindblad; Mikael Eriksson; KTH; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Astroparticle physics; Astropartikelfysik;

   Sammanfattning : This thesis develops techniques of control-methods, optimization, and diagnostics of accelerator equipment and the produced particle beams with emphasis on the Large Hadron Collider (LHC) project at CERN. From a solid knowledge of the characteristics of the manufactured accelerator equipment gained from in-depth measurements and analysis of measured data, a link to an enhanced equipment design can be made.

4. 28. Fundamental properties of neutrinos: masses and mixings

   Författare :Solveig Skadhauge; Matematisk fysik; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Matematisk och allmän teoretisk fysik; Fysik; Physics; quantum mechanics; classical mechanics; Mathematical and general theoretical physics; statistical physics; gravitation; relativity; statistisk fysik; termodynamik; thermodynamics; klassisk mekanik; kvantmekanik; relativitet; Fysicumarkivet A:2002:Skadhauge;

   Sammanfattning : Neutrino physics is one of the fastest growing topic in phenomenological high energy physics. Neutrinos are elementary neutral particles and participate only in the weak interactions. For this reason it is very difficult to detect them experimentally. Nevertheless, much experimental progress has been obtained in the recent years. LÄS MER

5. 29. Meson Properties in Partially Quenched Effective Field Theory

   Författare :Niclas Danielsson; Matematisk fysik; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; statistical physics; gravitation; relativity; quantum mechanics; classical mechanics; Mathematical and general theoretical physics; Fysik; Chiral Perturbation Theory; masses; decay constants; Physics; electromagnetic interactions; Strong interactions; pseudoscalar mesons; thermodynamics; Matematisk och allmän teoretisk fysik; klassisk mekanik; kvantmekanik; relativitet; statistisk fysik; termodynamik;

   Sammanfattning : Mass corrections and decay constants for light mesons have been calculated in Partially Quenched Chiral Perturbation Theory. The calculations of the charged meson masses have been performed to third order, first for degenerate quark masses, and then, in a second project, for the general case. LÄS MER

7. 30. Spectral Photon-Counting Computed Tomography with Silicon Detectors: New Models and Applications

   Författare :Fredrik Grönberg; Mats Danielsson; Mats Persson; Amir Pourmorteza; KTH; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; photon-counting; spectral computed tomography; material decomposition; pulse pileup; Compton scatter; image formation; fotonräknande; spektral datortomografi; materialbasupdelning; pulsöverlagring; Comptonspridning; bildbildning; Physics; Fysik;

   Sammanfattning : X-ray computed tomography (CT) is a widely used imaging modality that enables visualization of nearly every part of the human body. It is used for diagnosis of disease and injury as well as medical treatment planning. LÄS MER
