Sammanfattning : Periodic signal modeling plays an important role in different fields. The unifying theme of this thesis is using nonlinear techniques to model periodic signals. The suggested techniques utilize the user pre-knowledge about the signal waveform. This gives these techniques an advantage as compared to others that do not consider such priors. LÄS MER
2. Signal Processing as a Tool to Enhance Productivity in Industry : Measurement and Cancelation of Periodic Signals
Sammanfattning : Preface This licentiate thesis summarizes my work within the field of Signal Processing during my time in Signal Control Sweden AB from 1987 to 2002. The work has been performed in close co-operation the customers like Volvo Personvagnar AB, Sveriges Provnings- och forskningsinstitut and others. LÄS MER
Sammanfattning : In this thesis I present different experiments on superconducting circuits exploring parametric interactions with external signals and the vacuum in the microwave regime. These parametric processes are the result of the periodic modulation of a property of a system which results in different interactions. LÄS MER
Sammanfattning : Rolling element bearings are used in rotating machinery in various industry branches. Their health status must be monitored continuously in order to establish proper operational conditions in a production process. LÄS MER
Sammanfattning : Single-rate and multirate sampled-data (SD) systems as well as linear time periodic (LTP) systems with discrete jumps are analyzed in the frequency domain. The focus of the analysis is both on rejection of disturbances and on robust stability properties. LÄS MER
