1. Probabilistic Sequence Models with Speech and Language Applications
Abstract : Series data, sequences of measured values, are ubiquitous. Whenever observations are made along a path in space or time, a data sequence results. To comprehend nature and shape it to our will, or to make informed decisions based on what we know, we need methods to make sense of such data. READ MORE

2. Statistical modeling and design in forestry : The case of single tree models
Abstract : Forest quantification methods have evolved from a simple graphical approach to complex regression models with stochastic structural components. Currently, mixed effects models methodology is receiving attention in the forestry literature. READ MORE

3. Science versus School-science : Multiple models in genetics - The depiction of gene function in upper secondary textbooks and its influence on students' understanding
Abstract : In this thesis I describe a study of how the science of genetics is transformed into school science in upper secondary level textbooks and the impact that this transformation has on students’ understanding. The didactic challenge that we face is to decide which science from the academic disciplines we should bring into schools. READ MORE

4. Simplified models to evaluate nonlinear dynamics in hydropower rotors
Abstract : In hydropower systems, it is essential to avoid catastrophic failures that lead to human and economic losses. Unfortunately, a hydropower rotor can behave abnormally since several nonlinear effects occur during start-up, shut-downs or when running at nominal speed. READ MORE

5. Optimal Control and Model Reduction of Nonlinear DAE Models
Abstract : In this thesis, different topics for models that consist of both differential and algebraic equations are studied. The interest in such models, denoted DAE models, have increased substantially during the last years. READ MORE
