6. Identification and Control of Systems Subject to Abrupt Changes
Sammanfattning : Many different recursive identification methods for time varying systems have been suggested in the literature. An assumption that the variations in the system parameters are slow is common for almost all the methods. LÄS MER
7. Studies on identification of time-variant and time-varying nonlinear systems
Sammanfattning : This thesis addresses same aspects of nonlinear systemidentification. In par ticular, it is assumed that theconsidered systems can be described by the Wiener model whichconsists of a dynamit linear part followed by a nonbnear partor the Haxnmerstein model in which the order of these twoblocks is reversed.

8. Dynamic Load Models for Power Systems - Estimation of Time-Varying Parameters During Normal Operation
Sammanfattning : Economic and environmental concerns will slow down the expansion of the transmission system in many countries. The addition of new transmission lines will be few and far between. The de-regulation of the power supply will introduce new power flow patterns on the bulk transmission systems. LÄS MER
9. Essays on Mergers and Acquisitions and Event Studies
Sammanfattning : This dissertation consists of three studies on the anticipation of mergers and acquisitions (M&As) and its impact on takeover event studies. Article I investigates whether the market can anticipate both takeovers and their payment forms prior to their announcement dates. LÄS MER
10. Unconventional Monetary Policy at the International, National and Local Level
Sammanfattning : This thesis is based on four essays. The first investigates time-variation in the relationship between short interest rates and consumption in the USA and Sweden. Results based on Bayesian VAR models indicate that the short rate ceased to respond to consumption shocks when constrained by the zero lower bound. LÄS MER
