1. 11. Testing the boundaries for expectation effects in health and disease

   Författare :Moa Pontén; Karolinska Institutet; Karolinska Institutet; []
   Nyckelord :;

   Sammanfattning : Expectations affect our physiology and clinical outcomes, however the boundaries for this modulation are poorly understood. The purpose of this thesis is to investigate minimal requirements to elicit expectation effects on health-related outcomes, using experiments and an independent patient data meta-analysis. LÄS MER

3. 12. Spatio-Temporal Estimation for Mixture Models and Gaussian Markov Random Fields - Applications to Video Analysis and Environmental Modelling

   Författare :Johan Lindström; Matematisk statistik; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; vegetation; time series analysis; video segmentation; spatio-temporal modelling; precipitation; Markov chain Monte Carlo; Gaussian Markov random fields; expectation maximisation; change point detection; Bayesian recursive estimation; African Sahel; adaptive Gaussian mixtures;

   Sammanfattning : In this thesis computationally intensive methods are used to estimate models and to make inference for large, spatio-temporal data sets. The thesis is divided into two parts: the first two papers are concerned with video analysis, while the last three papers model and investigate environmental data from the Sahel area in northern Africa.

4. 13. Data association algorithms and metric design for trajectory estimation

   Författare :Abu Sajana Rahmathullah; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; metrics; smoothing; expectation maximization; Gaussian mixtures; data association; Trajectory estimation;

   Sammanfattning : This thesis is concerned with trajectory estimation, which finds applications in various fields such as automotive safety and air traffic surveillance. More specifically, the thesis focuses on the data association part of the problem, for single and multiple targets, and on performance metrics. LÄS MER

5. 14. Automatic segmentation in CMR - Development and validation of algorithms for left ventricular function, myocardium at risk and myocardial infarction

   Författare :Jane Tufvesson; Lund Klinisk fysiologi; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Automatic segmentation; cardiovascular magnetic resonance; validation; Expectation Maximization; freely available software; myocardial infarction;

   Sammanfattning : In this thesis four new algorithms are presented for automatic segmentation in cardiovascular magnetic resonance (CMR); automatic segmentation of the left ventricle, myocardial infarction, and myocardium at risk in two different image types. All four algorithms were implemented in freely available software for image analysis and were validated against reference delineations with a low bias and high regional agreement. LÄS MER

7. 15. Interrogation of Nucleic Acids by Parallel Threading

   Författare :Erik Pettersson; Joakim Lundeberg; Afshin Ahmadian; Ann-Christine Syvänen; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; genotyping; multiplex amplification; trinucleotide threading; single nucleotide polymorphism; genotype calling; Expectation-Maximization; protein-epitope signature tag; expression profiling; Human Protein Atlas; pooled genomic DNA; Pyrosequencing; 454; allelotyping; association studies; bioinformatics; Bioengineering; Bioteknik;

   Sammanfattning : Advancements in the field of biotechnology are expanding the scientific horizon and a promising era is envisioned with personalized medicine for improved health. The amount of genetic data is growing at an ever-escalating pace due to the availability of novel technologies that allow massively parallel sequencing and whole-genome genotyping, that are supported by the advancements in computer science and information technologies.
