Sammanfattning : 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. Turbulent jets in confined spaces application in mixing ventilation: experimental and numerical studiesDetta är en avhandling från Stockholm : KTH Royal Institute of Technology
Sammanfattning : 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.

- Detta är en avhandling från Uppsala : Acta Universitatis Upsaliensis
Sammanfattning : 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. LÄS MER
4. Isomeric yield ratio measurements with JYFLTRAP In quest of the angular momentum of the primary fragmentsDetta är en avhandling från Uppsala : Acta Universitatis Upsaliensis
Sammanfattning : 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. LÄS MER
5. Resonant magnetic perturbation effect on the tearing mode dynamics Novel measurements and modeling of magnetic fluctuation induced momentum transport in the reversed-field pinchDetta är en avhandling från Stockholm : KTH Royal Institute of Technology
Sammanfattning : 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. LÄS MER
