11. VAR Models, Cointegration and Mixed-Frequency Data
Sammanfattning : This thesis consists of five papers that study two aspects of vector autoregressive (VAR) modeling: cointegration and mixed-frequency data.Paper I develops a method for estimating a cointegrated VAR model under restrictions implied by the economy under study being a small open economy.

12. Model Checking Parameterized Timed Systems
Sammanfattning : In recent years, there has been much advancement in the area of verification of infinite-state systems. A system can have an infinite state-space due to unbounded data structures such as counters, clocks, stacks, queues, etc. It may also be infinite-state due to parameterization, i.e. LÄS MER
13. On State-Space Models in System Identification
Sammanfattning : This thesis considers identification of multivariable discrete time linear systems by using time-invariant state-space models of finite dimension. A new model structure is introduced that is fully parametrized, i. e. all matrices are filled with parameters. LÄS MER
14. Gibbs Measures and Phase Transitions in Potts and Beach Models
Sammanfattning : The theory of Gibbs measures belongs to the borderlandbetween statistical mechanics and probability theory. In thiscontext, the physical phenomenon of phase transitioncorresponds to the mathematical concept of non-uniqueness for acertain type of probability measures.The most studied model in statistical mechanics is thecelebrated Ising model.

15. Model Order Reduction with Rational Krylov Methods
Sammanfattning : Rational Krylov methods for model order reduction are studied. A dual rational Arnoldi method for model order reduction and a rational Krylov method for model order reduction and eigenvalue computation have been implemented. It is shown how to deflate redundant or unwanted vectors and how to obtain moment matching. LÄS MER
