  1. 1. Essays on Credit Risk

    Author : Caren Guo Nielsen; Lunds universitet.; Lund University.; [2015]
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Asset pricing; equity returns; size effect; value effect; momentum effect; credit risk effect; credit default swap; banks; asset risk; credit risk; portfolio choice; risk-based capital regulation; bank bailouts; moral hazard; distress risk; capital injections; TARP; CPP; market discipline; financial crisis;

    Abstract : This dissertation covers the issues related to credit risk that stem from the recent financial crisis and that are concerned by investors, financial intermediaries, and governments. The results of the research have important implications for asset managers, such as using the information from the credit risk market to rebalance stock portfolios, and for policy makers in regulating or bailing out banks.

  2. 2. Turbulent jets in confined spaces application in mixing ventilation: experimental and numerical studies

    University dissertation from Stockholm : KTH Royal Institute of Technology

    Author : Taghi Karimipanah; Högskolan i Gävle.; [1996]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; turbulent; wall jet; impinging jet; free jet; confinement effect; pressure; throw; experimental; numerical; corner; momentum; mixing ventilation;

    Abstract : The basis of mixing ventilation is the airflow supply to the room by means of jets initiatedfrom the ventilation diffusers. To avoid the draught problem, the design of mixing ventilationmakes uses the throw term, which is defined as the distance to the supply air terminal inwhich the jet centreline mean velocity is decreased to a given value.

  3. 3. Opening New Radio Windows and Bending Twisted Beams

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Erik Nordblad; Uppsala universitet.; Uppsala universitet.; [2011]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Orbital angular momentum; Hall effect; Nonparaxial beam; Geometrical optics; High frequency radio waves; Ray tracing; Magnetic zenith effect; Ionospheric irregularities; Wave propagation; Fysik med inriktning mot rymd- och plasmafysik; Physics with specialization in Space and Plasma Physics;

    Abstract : In ground based high frequency (HF) radio pumping experiments, absorption of ordinary (O) mode pump waves energises the ionospheric plasma, producing optical emissions and other effects. Pump-induced or natural kilometre-scale field-aligned density depletions are believed to play a role in self-focussing phenomena such as the magnetic zenith (MZ) effect, i. READ MORE

  4. 4. Isomeric yield ratio measurements with JYFLTRAP In quest of the angular momentum of the primary fragments

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Vasileios Rakopoulos; Uppsala universitet.; [2018]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Nuclear physics; nuclear fission; angular momentum; fission fragments; isomeric yield ratios; fission products; scission; Penning trap.; Physics with specialization in Nuclear Physics; Fysik med inriktning mot kärnfysik;

    Abstract : In this thesis, isomeric yield ratios of twenty nuclides produced in the fission of natU and 232Th by protons at 25-MeV and natU by high-energy neutrons were studied. The experiments were performed at the IGISOL-JYFLTRAP facility at the University of Jyväskylä. READ MORE

  5. 5. Resonant magnetic perturbation effect on the tearing mode dynamics Novel measurements and modeling of magnetic fluctuation induced momentum transport in the reversed-field pinch

    University dissertation from Stockholm : KTH Royal Institute of Technology

    Author : Richard Fridström; KTH.; [2017]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; RFP; reversed-field pinch; tokamak; tearing mode; RMP; fusion; plasma; resonant magnetic perturbation; stochastic; magnetic; field; viscosity; mode; locking; Electrical Engineering; Elektro- och systemteknik;

    Abstract : The tearing mode (TM) is a resistive instability that can arise in magnetically confined plasmas. The TM can be driven unstable by the gradient of the plasma current. When the mode grows it destroys the magnetic field symmetry and reconnects the magnetic field in the form of a so-called magnetic island. READ MORE
