6. Voltage Dip (Sag) Estimation in Power Systems based on Stochastic Assessment and Optimal Monitoring
Sammanfattning : This dissertation deals with the statistical characterization of the performance of power systems in terms of voltage dips (sags). It presents a method named voltage dip estimation that extends monitoring results to buses not being monitored. LÄS MER
7. Some Control Applications in Electric Power Systems
Sammanfattning : This thesis presents some control applications in electric power systems. The work consists of the four parts: interaction between DC cables and ship steering autopilots; frequency estimation; computer relaying; field tests using load switching to damp power oscillations. LÄS MER
8. On Receiver Algorithms for OFDM Systems
Sammanfattning : This thesis addresses the problem of designing a receiver for an Orthogonal FrequencyDivisionMultiplexing (OFDM)communication system operating over fading channels, taking into account the effects of hardware imperfections. We discuss solutions for efficiently estimating the parameters of a channel model and for compensating oscillator phase noise and analog to digital converter (ADC) quantisation errors at the receiver.

9. Contributions to generalized Wilcoxon rank tests
Sammanfattning : In unbalanced small sample size problems with right censorings, the variance estmators of linear rank statistics, may be biased. This is the case with the commonly applied variance estimators for the generalized Wilcoxon rank test statistics of Gehan and Prentice. LÄS MER
10. On Model Libraries for Thermo-hydraulic Applications
Sammanfattning : Mathematical modelling and simulation are important tools when dealing with engineering systems that today are becoming increasingly more complex. Tightly integrated production and process optimization are trends that give rise to heterogeneous systems, which are difficult to handle without expertise in several engineering disciplines. LÄS MER
