1. Seasonal Adjustment and Dynamic Linear Models
Abstract : Dynamic Linear Models are a state space model framework based on the Kalman filter. We use this framework to do seasonal adjustments of empirical and artificial data. A simple model and an extended model based on Gibbs sampling are used and the results are compared with the results of a standard seasonal adjustment method. READ MORE

2. Dynamic Interactions : National Political Parties, Voters and European Integration
Abstract : This thesis consists of an introduction and four self-contained papers, designated I-IV, which extend previous research on national political parties and voters in Western Europe. More specifically, the issues addressed are parties’ positions and voters’ opinions on European integration and their dynamic interactions, i.e. READ MORE

3. Bayesian Sequential Inference for Dynamic Regression Models
Abstract : Many processes evolve over time and statistical models need to be adaptive to change. This thesis proposes flexible models and statistical methods for inference about a data generating process that varies over time. The models considered are quite general dynamic predictive models with parameters linked to a set of covariates via link functions. READ MORE

4. Translation as Linear Transduction : Models and Algorithms for Efficient Learning in Statistical Machine Translation
Abstract : Automatic translation has seen tremendous progress in recent years, mainly thanks to statistical methods applied to large parallel corpora. Transductions represent a principled approach to modeling translation, but existing transduction classes are either not expressive enough to capture structural regularities between natural languages or too complex to support efficient statistical induction on a large scale.

5. Dynamic Train-Track Interaction: Linear and Non-Linear Track Models with Property Scatter
Abstract : A numerical method was developed to investigate the vertical dynamic behaviour of a railway track subjected to the loading of a moving train. The numerical simulations are carried out in the time-domain with what is known as a moving mass model. READ MORE
