2. 16. Spectroscopy of Stable and Radioactive Negative Ions

   Author : Annie Ringvall-Moberg; Göteborgs universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Atomic Physics; ISOLDE; CERN; Electron Correlation; Electron Affinity; Photodetachment; Negative Ions; Anions; Radioisotopes; Laser Photodetachment Spectroscopy; Resonance Ionization; Neutral Particle Detection; Wigner Threshold Law; Molecular Dissociation; RFQcb; DESIREE; Radiative Lifetimes;

   Abstract : Negative ions are unique quantum systems which are of fundamental interest within the field of atomic physics due to the importance of the electron correlation in their creation, stability, and existence. Properties of these ions, such as the electron affinity, i.e. READ MORE

4. 17. Parents, Children and Childbearing

   Author : Johan Dahlberg; Juho Härkönen; Gunnar Andersson; Jennifer S. Barber; Stockholms universitet; []
   Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Demography; Sociology; Fertility; Intergenerational transmission; Intergenerational influences; Social background; Parental death; Timing of first birth; Mode of delivery; Sibling correlation; Event history analysis; Childlessness; Sweden; sociologisk demografi; Sociological Demography;

   Abstract : This doctoral thesis provides a set of studies of social influences on fertility timing. Swedish register data are used to link individuals to their parents and siblings, thereby allowing the study of impacts of family of origin, social background, and parental death on fertility.

5. 18. Studies of PWO Crystals and Simulations of the p̅p →Λ̅Λ, Λ̅Σ0 Reactions for the PANDA Experiment

   Author : Sophie Grape; Tord Johansson; Per-Erik Tegnér; Kai-Thomas Brinkmann; Uppsala universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; PANDA; antiproton; PWO; hyperon; lambda; simulation; polarisation; spin correlation; Nuclear physics; Kärnfysik; Physics; fysik;

   Abstract : The thesis comprises investigations of two topics related to the PANDA experiment. The first part is dedicated to energy resolution and light yield uniformity studies of PWO crystals for the electromagnetic calorimeter. The second part of the thesis is dedicated to simulation studies of the p̅p→Λ̅Λ and the p̅p→Λ̅Σ0 channels. READ MORE

6. 19. Analysis of regional seismic data by means of higher-order spectra

   Author : Leif Persson; Uppsala universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Earth sciences; Geovetenskap; Earth sciences; Geovetenskap; Geofysik med inriktning mot seismologi; Geophysics with specialization in Seismology;

   Abstract : The use of higher-order statistical and spectral estimators as complementary analysis for conventional regional seismic data processing is studied. The issues addressed are; the properties of the complex bispectrum of regional seismic phases, the experimental detection performance of higher-order statistical detectors, discrimination between local earthquakes and explosions, statistical tests and bicoherence, biphase and spatial bispectrum analysis of regional P-, S, and Lg-phases.

7. 20. Modeling financial volatility : A functional approach with applications to Swedish limit order book data

   Author : Suad Elezovic; Xavier de Luna; Gunnar Rosenqvist; Umeå universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Financial data; functional time series; multivariate generalized least squares; seemingly unrelated autoregression; Statistics; computer and systems science; Statistik; data- och systemvetenskap; ekonometri; Econometrics;

   Abstract : This thesis is designed to offer an approach to modeling volatility in the Swedish limit order market. Realized quadratic variation is used as an estimator of the integrated variance, which is a measure of the variability of a stochastic process in continuous time. READ MORE
