2. 1. Selection of smoothing parameters with application in causal inference

   Author : Jenny Häggström; Xavier de Luna; Marie Wiberg; Yanyuan Ma; Umeå universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Smoothing parameter selection; Nonparametric regression; Semiparametric additive model; Double smoothing; Causal inference; BMI; Divorce; Statistics; Statistik; Statistics; statistik;

   Abstract : This thesis is a contribution to the research area concerned with selection of smoothing parameters in the framework of nonparametric and semiparametric regression. Selection of smoothing parameters is one of the most important issues in this framework and the choice can heavily influence subsequent results. READ MORE

4. 2. Sensitivity and Uncertainty Analysis of Boiling Water Reactor Stability Simulations

   Author : Ivan Gajev; Weimin Ma; Tomasz Kozlowski; Kostadin Ivanov; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; BWR Stability; Sensitivity; Uncertainty; SRA - Energy; SRA - Energi;

   Abstract : The best estimate codes are used for licensing of Nuclear Power Plants (NPP), but with conservative assumptions. It is claimed that the uncertainties are covered by the conservatism of the calculation. READ MORE

5. 3. On Fuel Coolant Interactions and Debris Coolability in Light Water Reactors

   Author : Sachin Thakre; Weimin Ma; Florian Fichot; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; severe accident; fuel-coolant interactions; melt jet fragmentation; steam explosion; debris bed coolability; uncertainty analysis; Energiteknik; Energy Technology;

   Abstract : During the case of a hypothetical severe accident in a light water reactor, core damage may occur and molten fuel may interact with water resulting in explosive interactions. A Fuel-Coolant Interactions (FCI) consists of many complex phenomena whose characteristics determine the energetics of the interactions. READ MORE

6. 4. A Factor Analytical Approach to Dynamic Panel Data Models

   Author : Milda Norkute; Nationalekonomiska institutionen; []
   Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Dynamic panel data models; Factor analytical method; Bias; Incidental trends; MA errors; Factor-GMM;

   Abstract : This thesis deals with the development and application of new estimation approaches based on factor analysis for estimation and inference in dynamic panel data models with fixed-effects. A new factor analytical method (FA) for the estimation of fixed-effects dynamic panel data models is proposed in Bai ("Fixed-Effects Dynamic Panel Models, A Factor Analytical Method". READ MORE

7. 5. Identification of dynamic errors-in-variables models

   Author : Kaushik Mahata; Torsten Söderström; Uppsala universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Signal Processing; Signalbehandling;

   Abstract : The problem of identifying dynamic errors-in-variables models is of fundamental interest in many areas like process control, array signal processing, astronomical data reduction. In recent years, this field has received increased attention of the research community. READ MORE
