11. Estimation of Nonlinear Dynamic Systems : Theory and Applications
Abstract : This thesis deals with estimation of states and parameters in nonlinear and non-Gaussian dynamic systems. Sequential Monte Carlo methods are mainly used to this end. These methods rely on models of the underlying system, motivating some developments of the model concept. READ MORE

12. Variation Control in Virtual Product Realization - A Statistical Approach
Abstract : All manufacturing processes are afflicted by variation, which leads to products that may not fulfill assembly, functional or esthetical requirements. The variation in the final product originates from variation in individual parts and assembly processes. READ MORE

13. A Methodology to Control the Microstructure of Plasma Sprayed Coatings
Abstract : The aim of this thesis is to enhance the overall understanding of the plasma spray process and increase control and reproducibility of the coating properties. This was performed by establishment of relationships between controllable process parameters, in-flight properties of the injected particles (velocity and temperature), and microstructure properties.

14. Event Prediction and Bootstrap in Time Series
Abstract : Alarm systems are used in many situations, and should be as efficient as possible. In this thesis optimal predictive alarm systems, event predictors, are presented for general linear time series models with external signals. This family of process models include e.g. READ MORE

15. Improving Software Quality through Understanding and Early Estimations
Abstract : Software quality is an important factor of a large and complex software system. Hence, there is a need for measuring and controlling quality. Software quality has, however, many different f actors and involves implicit expectations of the behaviour of the software. READ MORE
