12. Identification of Stochastic Nonlinear Dynamical Models Using Estimating Functions
Abstract : Data-driven modeling of stochastic nonlinear systems is recognized as a very challenging problem, even when reduced to a parameter estimation problem. A main difficulty is the intractability of the likelihood function, which renders favored estimation methods, such as the maximum likelihood method, analytically intractable. READ MORE

13. Low-angle estimation : Models, methods and bounds
Abstract : In this work we study the performance of elevation estimators and lower bounds on the estimation error variance for a low angle target in a smooth sea scenario using an array antenna. The article is structured around some key assumptions on multipath knowledge, signal parameterization and noise covariance, giving the reader a framework in which Maximum Likelihood estimators exploiting different á priori information can be found.

14. The West European market for secondary aluminium : supply and demand models
Abstract : This thesis consists of two self-contained papers on the West European market for aluminium metal made from scrap, so called secondary aluminium. The purpose of the first paper is to identify and estimate the relative importance of factors determining supply and demand of secondary aluminium casting alloys in the short-run. READ MORE

15. Effective Sampling Design for Groundwater Transport Models
Abstract : Model reliability is important when groundwater models are used for evaluation of environmental impact and water resource management. Model attributes such as geohydrologic units and parameter values need to be quantified in order to obtain reliable results. READ MORE
