2. 1. Noise Applications in Light Water Reactors with Traveling Perturbations

   Author : Victor Dykin; Chalmers tekniska högskola; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Green s function technique; transit times; decay ratio; cross-correlation function; void fraction; global and regional instabilities; propagating density perturbation; BWR stability; reduced order models; non-white driving force; local component; Monte Carlo; space-dependent neutron noise; density wave oscillations;

   Abstract : Neutron noise induced by perturbations traveling with the coolant of light water reactors (LWRs) is investigated. Different methods to simulate the effect of propagating perturbations are considered. The studies are performed in both open- and closed-loop systems and summarized in three chapters. READ MORE

4. 2. Femtosecond Dynamics and Photochemistry in Solution

   Author : Marcus Rasmusson; Kemisk fysik; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Kemi; Chemistry; cross-correlation function; chloroiodomethane; dihalides; bromobenzene; ion pairs; solvation; vibrational relaxation; charge-transfer; tetranitromethane; electron transfer; femtosecond spectroscopy; dissociation; Photochemistry; Fotokemi; Chemical technology and engineering; Kemiteknik och kemisk teknologi;

   Abstract : The reaction dynamics of several polyatomic systems have been investigated in solution by femtosecond spectroscopy. Tetranitromethane-naphtalene complexes excited in the charge-transfer band at 400 nm undergo dissociative electron transfer, resulting in three primary products: [naphthalene].+, NO2 and C(NO2)3-.

5. 3. Properties of heavy rainfall in an East Asian monsoon catchment - Analysis of daily rain gauge data

   Author : Cecilia Svensson; Avdelningen för Teknisk vattenresurslära; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; China.; Huai River; East Asian monsoon; typhoon; Mei-Yu front; fractals; empirical orthogonal function analysis; correlation analysis; probable maximum precipitation; storm movement; seasonal occurrence; Rainfall; spatial pattern; Hydrogeology; geographical and geological engineering; Hydrogeologi; teknisk geologi; teknisk geografi; Geophysics; physical oceanography; meteorology; Geofysik; fysisk oceanografi; meteorologi;

   Abstract : The East Asian monsoon has a strong seasonal effect on the rainfall regime of Eastern China. In order to mitigate floods and conserve the water for use throughout the year, dams and other hydro-structures are built. The design of the structures requires knowledge of the rainfall characteristics that influence the inflow to them. READ MORE

6. 4. Essays in Quantitative Finance

   Author : Patrik Karlsson; Nationalekonomiska institutionen; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; credit valuation adjustment CVA ; derivative pricing; interest rate derivatives; Monte Carlo simulation;

   Abstract : This thesis contributes to the quantitative finance literature and consists of four research papers.Paper 1. This paper constructs a hybrid commodity interest rate market model with a stochastic local volatility function that allows the model to simultaneously fit the implied volatility of commodity and interest rate options.
