    Keywords : Engineering and Technology Electrical Engineering; Electronic Engineering; Information Engineering Signal Processing; Teknik och teknologier Elektroteknik och elektronik Signalbehandling; TECHNOLOGY Information technology Signal processing; TEKNIKVETENSKAP Informationsteknik Signalbehandling; Elektroteknik med inriktning mot reglerteknik; Electrical Engineering with specialization in Automatic Control; 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;

    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.

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

    University dissertation from Lund University

    Author : Naveed Butt; Lunds universitet.; Lund University.; [2011]
    Keywords : NQR; Detection; NMR; Raman Spectroscopy; Spectral Analysis.; TEKNIKVETENSKAP; TECHNOLOGY;

    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

  3. 3. Decay Properties and Hyperfine Interactions in Oriented Alpha-, Beta- and Gamma-emitting Nuclei

    University dissertation from Chalmers University of Technology

    Author : Mats Lindroos; Chalmers tekniska högskola.; Chalmers University of Technology.; [1993]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Fysik; Physics;

    Abstract : The hyperfine interaction has often been described as the bridge between atomic physics and nuclear physics. On the one hand it enables us to study important nuclear phenomena which only manifest themselves in the strong internal fields originating from the surrounding electrons and on the other hand it enables us to study properties of the atomic system or of condensed matter using nuclear probes.

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Axel Rydevik; Uppsala universitet.; [2014]
    Keywords : Medical and Health Sciences Basic Medicine Medicinal Chemistry; Medicin och hälsovetenskap Medicinska grundvetenskaper Läkemedelskemi; Pharmaceutical Sciences; Farmaceutisk vetenskap; Cunninghamella blakesleeana; Cunninghamella elegans; Doping Control; Drug Metabolites; Glucuronide Production; Mass Spectrometry; Reactive Metabolites; Reference Material; Structural Characterization; Analytical Pharmaceutical Chemistry; Analytisk farmaceutisk kemi;

    Abstract : This thesis describes the in vitro production of drug metabolites using fungi of the Cunninghamella species. The metabolites were characterized with mainly liquid chromatography-mass spectrometry using ion-trap and quadrupole-time-of-flight instruments. A fungal in vitro model has several advantages e.g. READ MORE
