11. Optimal Control and Model Reduction of Nonlinear DAE Models
Sammanfattning : 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. LÄS MER
12. Learning probabilistic models of dynamical phenomena using particle filters
Sammanfattning : Dynamical behavior can be seen in many real-life phenomena, typically as a dependence over time. This thesis studies and develops methods and probabilistic models for statistical learning of such dynamical phenomena.A probabilistic model is a mathematical model expressed using probability theory.

13. Classical and Quantum Correlations in Microwave Frequency Combs
Sammanfattning : Denna avhandling undersöker korrelationer i frekvensdomänen, av både klassiskt och kvantmekaniskt ursprung, i icke-linjära mikrovågskretsar. Syftet är att utveckla en kompakt metod för att generera kvantmekaniska korrelationer mellan harmoniska oscillatorer (s.k. LÄS MER
14. Identification and Estimation for Models Described by Differential-Algebraic Equations
Sammanfattning : Differential-algebraic equations (DAEs) form the natural way in which models of physical systems are delivered from an object-oriented modeling tool like Modelica. Differential-algebraic equations are also known as descriptor systems, singular systems, and implicit systems. LÄS MER
15. Generation and Transmission of Optical Solitons at Ultrahigh Bit Rates
Sammanfattning : This thesis deals with the generation and transmission of optical solitons in ultrahigh-speed fiber-optic communication systems. For optical soliton pulses the fiber dispersion and nonlinearity can under certain circumstances cancel each other, thus allowing the solitons to remain undistorted over long distances. LÄS MER
