2. 1. Detection and Classification in Electrocardiac Signals

   Author : Magnus Åström; Institutionen för elektro- och informationsteknik; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Signalbehandling; Signal processing; morphology classification; QRS detection; ischemia; body position changes; electrogram; ECG; electrocardiogram; clustering; classification; Detection; sensing;

   Abstract : Signal processing can be used to condition medical signals to facilitate their interpretation, and to extract clinically important information. The purpose of the present doctoral thesis is to put forward solutions to certain problems encountered in the processing of electrocardiac signals. READ MORE

4. 2. 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

5. 3. Statistical modelling in chemistry - applications to nuclear magnetic resonance and polymerase chain reaction

   Author : Halfdan Grage; Teknisk mikrobiologi; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Statistik; operationsanalys; programmering; aktuariematematik; programming; actuarial mathematics; Statistics; operations research; experimental design.; logistic regression; detection probability; region of operability; sampling. Diagnostic PCR; Cramér-Rao bounds; maximum likelihood estimation; NMR spectroscopy; Gaussian noise;

   Abstract : This thesis consists of two parts with the common theme of statistical modelling in chemistry. The first part is concerned with applications in nuclear magnetic resonance (NMR) spectroscopy, while the second part deals with applications in polymerase chain reaction (PCR). READ MORE

6. 4. Finite Element Modelling of Eddy Current Non-Destructive Evaluation in Probability of Detection Studies

   Author : Anders Rosell; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Eddy Current; Model Based Probability of Detection; Probability of Detection; Non-destructive Evaluation; Finite Element Modelling;

   Abstract : The goal of this work has been to evaluate the possibility to use mathematical modelling to characterize the capability and reliability of automated eddy current inspections. The safety in aerospace propulsion is critical. Components that are critical for the operation are therefore designed to withstand material degradation. READ MORE

7. 5. Urban Change Detection Using Multitemporal SAR Images

   Author : Osama Yousif; Yifang Ban; Lorenzo Bruzzone; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Change detection; High resolution; Image denoising; Kittler-Illingworth; MAP-MRF; Multitemporal SAR images; Nonlocal means; Object-based; Otsu; Outlier detection; Remote sensing; SAR speckle; Urban; Geodesy and Geoinformatics; Geodesi och geoinformatik;

   Abstract : Multitemporal SAR images have been increasingly used for the detection of different types of environmental changes. The detection of urban changes using SAR images is complicated due to the complex mixture of the urban environment and the special characteristics of SAR images, for example, the existence of speckle.
