16. Microwave Gaussian quantum metrology
Sammanfattning : With increasingly sensitive measurements being made possible by technological development, there arises situations where the effects of quantum mechanics have to be taken into account. While quantum mechanics tells us that there are fundamental limits of measurement sensitivity, it also gives us the tools to constructively push the same limits for experimental systems. LÄS MER
17. Nonlinear Structural Identification Using a Multi-Harmonic Frequency Response Functions
Sammanfattning : In industrial structural dynamics problems, linear FE-models commonly serve to represent the global structural behavior. However, when test data are available they often show evidence of nonlinear dynamic characteristics. In that case, an initial linear model may be judged insufficient in representing the dynamics of the structure. LÄS MER
18. Model Calibration of Nonlinear Mechanical Systems Using Multi-Harmonic Frequency Response Functions
Sammanfattning : In industry, linear finite element models are commonly employed to represent global structural behavior. It is crucial that the computational models are able to accurately represent the structures’ behavior. This cannot always be achieved by the use of linear models. LÄS MER
19. On Detection and Estimation of Multiple Sources in Radar Array Processing
Sammanfattning : This thesis deals with detection and estimation problems in sensor array signal processing. We treat the multiple hypothesis problem for complex sinusoids observed in spatially colored noise. LÄS MER
20. Channel Estimation and Self-Interference Suppression for MIMO Relaying Systems
Sammanfattning : Recently, the introduction of relaying nodes in wireless channels has been identified as a promising technique for providing broader coverage, higher transmission rates, and increased reliability. Moreover, when the concept of relaying systems is combined with that of multiple-input multiple-output (MIMO) technology, thesystem performance can be further improved by exploiting the spatial dimension.
