2. 11. Change point detection with respect to variance

   Author : Elias Erdtman; Martin Singull; Dietrich von Rosen; Nader Tajvidi; Linköpings universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES;

   Abstract : This thesis examines a simple method for detecting a change with respect to the variance in a sequence of independent normally distributed observations with a constant mean. The method filters out observations with extreme values and divides the sequence into equally large subsequences. READ MORE

4. 12. On Detection and Estimation of Multiple Sources in Radar Array Processing

   Author : Jonny Eriksson; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; spatially correlated noise; Cramer-Rao bounds; estimation; feature reduction; virtual uniform linear arrays; classification; adaptive data reduction; nonlinear weighted least squares; multiple targets; detection;

   Abstract : This thesis deals with detection and estimation problems in sensor array signal processing. We treat the multiple hypothesis problem for complex sinusoids observed in spatially colored noise. READ MORE

5. 13. On model assisted probability of detection in eddy current evaluation

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

   Abstract : The goal of this work has been to investigate the possibility to use mathematical modelling to characterize the capability and reliability of automated eddy current (EC) inspections. EC evaluation is one of the most applied methods for non-destructive evaluation (NDE) and is studied within this work. READ MORE

6. 14. Detection and Characterisation of Salmonella in Animal Feed Samples by PCR-Based Methods

   Author : Charlotta Löfström; Teknisk mikrobiologi; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Food and drink technology; Livsmedelsteknik; Biotechnology; Bioteknik; Biokemisk teknik; Biochemical technology; Analytisk kemi; Analytical chemistry; mykologi; virologi; bakteriologi; Mikrobiologi; validation; Microbiology; bacteriology; virology; mycology; Salmonella; ribotyping; detection; animal feed; randomly amplified polymorphic DNA; pulsed-field gel electrophorsis; pre-PCR processing; PCR; polymerase chain reaction; genotyping;

   Abstract : Animal feed is a recognised source of Salmonella enterica for farm livestock and may also indirectly cause infection in people consuming foods of animal origin. It is therefore important to have rapid, reproducible and specific methods for the detection of Salmonella in feed, and for the characterisation of strains for further epidemiological investigations or to trace the source of contamination in a production facility.

7. 15. Change Detection Using Multitemporal SAR Images

   Author : Osama Yousif; Yifang Ban; Lorenzo Bruzzones; KTH; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Change detection; ENVISAT ASAR; ERS-2 SAR; image denoising; Kittler-Illingworth algorithm; MAP-MRF classifier; modified ratio; multitemporal SAR images; nonlocal means NLM ; SAR speckle; urbanization;

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