1. Real-time breath gas analysis of carbon monoxide : laser-based detection and pulmonary gas exchange modeling
Sammanfattning : Breath gas analysis is a promising approach for non-invasive medical diagnostics and physiological monitoring. Real-time, breath-cycle resolved biomarker detection facilitates data interpretation and has the potential to improve the diagnostic value of breath tests as exhalation profiles carry spatiotemporal information about biomarker origin and gas exchange in the respiratory tract.

2. Estimation Using Low Rank Signal Models
Sammanfattning : Designing estimators based on low rank signal models is a common practice in signal processing. Some of these estimators are designed to use a single low rank snapshot vector, while others employ multiple snapshots. This dissertation deals with both these cases in different contexts. LÄS MER
3. On gene regulatory networks and data fitting
Sammanfattning : Living organisms can be viewed as complex biological machines. In order to function, they must regulate their internal mechanism to do the right thing, at the right time, and in the right amount. Part of this regulation is encoded in gene regulatory networks. LÄS MER
4. Vehicle Size and Orientation Estimation Using Geometric Fitting
Sammanfattning : Over the years imaging laser radar systems have been developed for both military and civilian applications. Among the applications we note collection of 3D data for terrain modelling and object recognition. One part of the object recognition process is to estimate the size and orientation of the object.

5. High-Sensitivity High-Resolution Diode Laser Spectroscopy in the Near-Infrared Region
Sammanfattning : High-resolution spectroscopy measurements have been performed using near-infrared diode lasers. Special emphasis was placed upon high accuracy absorption lineshape measurements, which provide the basis for quantitative gas analysis. For this purpose, relevant spectral characteristics of the radiation emitted by diode lasers were studied. LÄS MER
