2. 1. ROBUST DETECTION AND SPECTRAL ANALYSIS OF SIGNALS WITH APPLICATIONS IN SPECTROSCOPY

   Author : Naveed Butt; Matematisk statistik; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Detection; NQR; NMR; Raman Spectroscopy; Spectral Analysis.;

   Abstract : Modern spectroscopic techniques, such as nuclear quadrupole resonance (NQR), nuclear magnetic resonance (NMR), and Raman spectroscopy, rely heavily on statistical signal processing systems for decision making and information extraction. The first part of this thesis introduces novel robust algorithms for detection, estimation, and classification of signals obtained through these spectroscopic techniques. READ MORE

4. 2. Signal Processing for Spectroscopic Applications

   Author : Erik Gudmundson; Peter Stoica; Peter Händel; Stoica Stoica; Uppsala universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; spectral estimation; spectroscopic techniques; MRI; NMR; NQR; signal detection; parameter estimation; missing data; non-uniform sampling; damped sinusoids; detection of explosives; T1-mapping; relaxometry; brain imaging; skin imaging; blood velocity estimation; medical ultrasound; Signal processing; Signalbehandling; Elektroteknik med inriktning mot reglerteknik; Electrical Engineering with specialization in Automatic Control;

   Abstract : Spectroscopic techniques allow for studies of materials and organisms on the atomic and molecular level. Examples of such techniques are nuclear magnetic resonance (NMR) spectroscopy—one of the principal techniques to obtain physical, chemical, electronic and structural information about molecules—and magnetic resonance imaging (MRI)—an important medical imaging technique for, e.

5. 3. Biochip design based on tailored ethylene glycols

   Author : Andréas Larsson (Kaiser); Bo Liedberg; Tommy Nylander; Linköpings universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Biosensor; biochip; poly ethylene glycol ; self-assembled monolayer; photopolymerisation; microarray; biomolecular interaction; explosives detection; Physics; Fysik;

   Abstract : Studies of biomolecular interactions are of interest for several reasons. Beside basic research, the knowledge gained from such studies is also very valuable in for example drug target identification. Medical care is another area where biomolecules may be used as biomarkers to aid physicians in making correct diagnosis. READ MORE

6. 4. MEMS Interfaces for Bioanalysis Systems

   Author : Thomas Frisk; Göran Stemme; Andreas Hierlemann; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; microfluidic interfacing; microfluidics; µTAS; sample transfer; biosensor; electronic nose; surface tension; quartz crystal microbalance; QCM; narcotics detection; Electronic measurement and instrumentation; Elektronisk mät- och apparatteknik;

   Abstract : This thesis deals with various aspects of using open microfluidic interfaces. Three specific areas of application are studied. The first is air-to-liquid interfacing in biosensors with possibilities for component inte­gration. A micromachined interface for airborne sample-to-liquid and droplet-to-liquid adsorption is discussed. READ MORE

7. 5. Studies of partial oxidation and combustion over heterogeneous catalysis by transient experiments
