1. 6. On Bounds and Asymptotics of Sequential Monte Carlo Methods for Filtering, Smoothing, and Maximum Likelihood Estimation in State Space Models

   Författare :Jimmy Olsson; Matematisk statistik; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; actuarial mathematics; programming; operations research; Statistics; Matematik; Mathematics; state space models; smoothing; sequential Monte Carlo; particle filter; EM algorithm; maximum likelihood; consistency; Asymptotic normality; Statistik; operationsanalys; programmering; aktuariematematik;

   Sammanfattning : This thesis is based on four papers (A-D) treating filtering, smoothing, and maximum likelihood (ML) estimation in general state space models using stochastic particle filters (also referred to as sequential Monte Carlo (SMC) methods). The aim of Paper A is to study the bias of Monte Carlo integration estimates produced by the so-called bootstrap particle filter. LÄS MER

3. 7. Structural and dynamical basis of NusA´s role in transcription-coupled DNA repair

   Författare :Damasus Okeke; Göteborgs universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Resonance assignment; DNA repair; transcription-repair coupling factors; transcription-coupled repair; NusA; DinB; UvrD; autoinhibition; DNA substrate; dynamics.;

   Sammanfattning : DNA repair processes involves a host of repair machineries that are able to recognize and repair the damaged DNA. Nucleotide excision repair (NER) pathway is one of these processes exploited by cells to remove bulky DNA lesions. LÄS MER

4. 8. Multiple Model Filtering and Data Association with Application to Ground Target Tracking

   Författare :Daniel Svensson; Chalmers tekniska högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Multiple model filtering; semi-Markov processes; multi-target tracking; FISST; state estimation; IMM; performance evaluation; OSPA; PHD; ground target tracking; Kalman filtering; target tracking; CPHD; MHT; random finite sets;

   Sammanfattning : This thesis is concerned with two central parts of a tracking system, namely multiple-model filtering and data association. Multiple models are introduced to provide accurate filtering, whereas data association deals with the unknown origin of the received measurements. LÄS MER

5. 9. Corruption, Distortions and Development

   Författare :Sebastian Jävervall; Niklas Bengtsson; Eva Mörk; Jakob Svensson; Uppsala universitet; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Accountability; Corruption; Economic Development; Information Disclosure; International Trade; Meritocracy; Political Distortions; Social Unrest; State Capacity; Economics; Nationalekonomi;

   Sammanfattning : Essay I: Does increased government transparency make bureaucracies more meritocratic? I study the impact of politician disclosure requirements on the assignment of bureaucrats to public posts. I collect detailed information on bureaucrats' qualifications and construct a novel measure of bureaucratic mismatch—an index measuring the extent to which a bureaucrat is under- or overqualified to perform a specific task.

7. 10. Structure and Dynamics in Transition Metal Perovskites — An Optical Spectroscopy Study

   Författare :Johan Bielecki; Chalmers tekniska högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; multiferroics; colossal magnetoresistance; magnetism; proton-conduction; spin-state transition; structure; Ultrafast spectroscopy; high temperature superconductivity; dynamics; Raman;

   Sammanfattning : Transition metal oxides with the perovskite structure exhibit a vast number of exotic properties due to the large number of competing degrees of freedom at the Fermi surface. Together with couplings between and correlations within these degrees of freedom, this class of materials is of high interest from both a practical and theoretical point of view. LÄS MER
