1. Dicke narrowing and speed-dependent effects in dispersion signals : Influence on assessment of concentration and spectral parameters by noise-immune cavity-enhanced optical heterodyne molecular spectrometry
Sammanfattning : Laser spectroscopic techniques have, during the last decades, demonstrated an extraordinary capability for sensitive detection of molecular constituents in gas phase. Since spectra from such techniques constitute unique and characteristic signatures for each type of species, these techniques enable investigations of molecular structures as well as detection of the presence of species in a gas mixture.

2. Continuous-time System Identification : Refined Instrumental Variables and Sampling Assumptions
Sammanfattning : Continuous-time system identification deals with the problem of building continuous-time models of dynamical systems from sampled input and output data. There are two main approaches in this field: indirect and direct. In the indirect approach, a suitable discrete-time model is first determined, and then it is transformed into continuous-time.

3. Teatermusikaliska ljudhändelser. Ett bidrag till studiet av musik och angränsande ljudobjekt i talteater och opera
Sammanfattning : This dissertation focuses primarily on the following aspects concerning music in theatre: 1) its experienced peculiarity – ontologically grounded, 2) its sounding scope, and 3) its various kinds of functions. I argue that the difference between spoken theatre and opera is a question of degree rather than essence, and consider such an assertion being especially valid for the music of these genres. LÄS MER
4. Indirect System Identification for Unknown Input Problems : With Applications to Ships
Sammanfattning : System identification is used in engineering sciences to build mathematical models from data. A common issue in system identification problems is that the true inputs to the system are not fully known. In this thesis, existing approaches to unknown input problems are classified and some of their properties are analyzed. LÄS MER
5. Analysis of Some Methods for Identifying Dynamic Errors-in-variables Systems
Sammanfattning : A system where errors or noises are present on both the inputs and the outputs is called an errors-in-variables (EIV) system. EIV systems appear in industrial and agricultural processes, medical sciences, economical systems, biotechnology, as well as in many other areas. LÄS MER
