1. Simplicity within Complexity : Understanding dynamics of cellular networks by model reduction
Abstract : Cellular networks composed of interactions between genes, proteins and metabolites, determines the behavioural repertoire of the cell. Recent developments in high-throughput experimental techniques and computational methods allow static descriptions of these networks on a genome scale. READ MORE

2. Model Order Reduction Based on Semidefinite Programming
Abstract : The main topic of this PhD thesis is complexity reduction of linear time-invariant models. The complexity in such systems is measured by the number of differential equations forming the dynamical system. This number is called the order of the system. READ MORE

3. Model Reduction Using Semidefinite Programming
Abstract : In this thesis model reduction methods for linear time invariant systems are investigated. The reduced models are computed using semidefinite programming. Two ways of imposing the stability constraint are considered. However, both approaches add a positivity constraint to the program. READ MORE

4. Structural and evolutionary aspects of stochastic processes
Abstract : Stochastic processes constitute a broad class of objects of central importance in complex systems. The main structural aspect of stochastic processes that is treated in this thesis is their hierarchical dynamics. READ MORE

5. Modeling and Model Reduction in Automotive Systems
Abstract : The current control design development process in automotive industry and elsewhere involves many expensive experiments and hand-tuning of control parameters. Model based control design is a promising approach to reduce costs and development time. In this process low complexity models are essential. READ MORE
