  1. 1. Split Trees, Cuttings and Explosions

    University dissertation from Uppsala : Department of Mathematics

    Author : Cecilia Holmgren; Uppsala universitet.; [2010]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Random Graphs; Random Trees; Split Trees; Renewal Theory; Binary Search Trees; Cuttings; Records; Tree Algorithms; Markov Chains; Galton-Watson Processes; MATHEMATICS; MATEMATIK; Mathematics; Matematik;

    Abstract : This thesis is based on four papers investigating properties of split trees and also introducing new methods for studying such trees. Split trees comprise a large class of random trees of logarithmic height and include e.g., binary search trees, m-ary search trees, quadtrees, median of (2k+1)-trees, simplex trees, tries and digital search trees.

  2. 2. An Experimental Study on the Dynamics of a Single Droplet Vapor Explosion

    University dissertation from Stockholm : KTH

    Author : Roberta Concilio Hansson; KTH.; [2010]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; steam explosions; radiography; melt preconditioning; noncondensable gas; NATURAL SCIENCES Physics Nuclear physics Low energy physics; NATURVETENSKAP Fysik Kärnfysik Lågenergifysik;

    Abstract : The present study aims to develop a mechanistic understanding of the thermal-hydraulic processes in a vapor explosion, which may occur in nuclear power plants during a hypothetical severe accident involving interactions of high-temperature corium melt and volatile coolant. Over the past several decades, a large body of literature has been accumulated on vapor explosion phenomenology and methods for assessment of the related risk. READ MORE

  3. 3. Surface Coatings as Xenon Diffusion Barriers for Improved Detection of Clandestine Nuclear Explosions

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Lisa Bläckberg; Uppsala universitet.; [2014]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Radioxenon; Gas Diffusion Barrier; Plastic Scintillator; Comprehensive Nuclear-Test-Ban Treaty; Atomic Layer Deposition; Al2O3; Molecular Dynamics; Light Transport;

    Abstract : This thesis investigates surface coatings as xenon diffusion barriers on plastic scintillators. The motivation for the work is improved radioxenon detection systems, used within the verification regime of the Comprehensive Nuclear-Test-Ban Treaty (CTBT).One type of radioxenon detection systems used in this context is the Swedish SAUNA system.

  4. 4. Shock wave effects on the vascular endothelium

    University dissertation from Stockholm : Karolinska Institutet, Karolinska Institutet, Stockholm Söder Hospital

    Author : Anders Sondén; Karolinska Institutet.; Karolinska Institutet.; [2002]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Shock waves; cavitation; explosions; high-energy missile trauma; ESWL; laser; endothelial cells; cell membrane damage; cytoskeleton; adhesion molecules; reactive oxygen species;

    Abstract : A shock wave is a pressure wave with high amplitude and a velocity above sound. Man is exposed to shock waves (SWs) in connection with trauma, e.g. explosions and high-energy missiles and medical treatments such as extracorporeal lithotripsy (ESWL). READ MORE

  5. 5. Supernova remnants and their pulsar wind nebulae

    University dissertation from Stockholm : Department of Astronomy, Stockholm University

    Author : Natalia Lundqvist; Stockholms universitet.; [2012]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; pulsars; supernovae; ISM; Astronomy; astronomi;

    Abstract : Massive stars die in powerful stellar explosions, so-called supernovae. In most cases, a neutron star or a black hole is expected to form in the center. The ejected material in these explosions expands out into the surroundings for tens of thousands of years, forming a supernova remnant. If a rapidly rotating neutron star, i. READ MORE
