1. On Model Simplification in System Identification
Sammanfattning : This report deals with the connection between system identification and model reduction. We propose an identification algorithm that is based on the least squares identification method and either of the model reduction techniques: Frequency weighted truncated balanced realization or frequency weighted optimal Hankel-norm model reduction.

2. Model Reduction for Control of Stirred Tank Reactor Processes
Sammanfattning : Models of chemical processes have a tendency of being far too complex for controller design. In many cases these models are also too complex for simulation together with other sub-systems, due to long simulation times and numerical problems. LÄS MER
3. In Search of Strategic Consistency - A Model for Evaluation of how Stategies Support Objectives
Sammanfattning : Developments during recent years have brought a divergence between strategic management theory and practice. While practitioners perceive an undiminished need for identification and implementation of appropriate strategic directions of companies, theorists have stressed the limitations that apply to rational strategic analysis and decision-making.

4. Model Reduction for Linear Time-Varying Systems
Sammanfattning : The thesis treats model reduction for linear time-varying systems. Time-varying models appear in many fields, including power systems, chemical engineering, aeronautics, and computational science. They can also be used for approximation of time-invariant nonlinear models. Model reduction is a topic that deals with simplification of complex models. LÄS MER
5. Simplicity within Complexity : Understanding dynamics of cellular networks by model reduction
Sammanfattning : 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. LÄS MER
