  2. 36. Laser-Induced Incandescence and Complementary Diagnostics for Flame Soot Characterization

    Author : Nils-Erik Olofsson; Förbränningsfysik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Fysicumarkivet A:2015:Olofsson;

    Abstract : This work has been aimed at developing and applying laser-induced incandescence (LII) for flame soot characterization. The basic principle of LII is rapid heating of the soot particles to temperatures of 3500-4000 K by short laser pulses. Thereby the intensity of the soot incandescence is increased. READ MORE

  4. 37. Physics of Aftershocks in the South Iceland Seismic Zone : Insights into the earthquake process from statistics and numerical modelling of aftershock sequences

    Author : Mattias Lindman; Roland Roberts; Björn Lund; David Marsan; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Earthquake processes; Aftershocks; Physics of aftershocks; Omori law; Postseismic processes; Pore pressure diffusion; Poroelasticity; Statistical seismology; Self-organised criticality; Interevent time distributions; Waiting time distributions; Geophysics; Geofysik;

    Abstract : In seismology, an important goal is to attain a better understanding of the earthquake process. In this study of the physics of aftershock generation, I couple statistical analysis with modelling of physical processes in the postseismic period. READ MORE

  6. 39. Nuclear spin interactions and coherent control in rare-earth-ion-doped crystals for quantum computing

    Author : Hafsa Syed; NanoLund: Centre for Nanoscience; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; rare-earth-ion-doped crystals; nuclear spins; magnetic dipole-dipole interactions; flip-flop interactions; quantum computing; high-fidelity;

    Abstract : This thesis work concerns studies of two rare-earth-ions, praseodymium (Pr3+) and europium (Eu3+), doped into a yttrium orthosilicate (Y2SiO5) crystal for applications in quantum computing. The nuclear spin levels of these ions can have very long coherence times, up to several hours. READ MORE

  7. 40. Impact of Heterobasidion spp. root rot in conifer trees and assessment of stump treatment : with emphasis on Picea abies, Pinus sylvestris and Larix × eurolepis

    Author : Liying Wang; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Abstract : In the thesis four studies were conducted to understand the impact of Heterobasidion spp. on Picea abies, Pinus sylvestris, and Larix × eurolepis in southern Sweden, and the efficacy of stump treatment against infection in order to economically assess control measures. The ability of secondary spread of H. READ MORE
