1. 21. Deep Regression and Segmentation for Medical Inference from Large-Scale Magnetic Resonance Imaging

   Författare :Taro Langner; Joel Kullberg; Anders Eklund; Uppsala universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Magnetic resonance imaging; medical image analysis; neural networks; machine learning; semantic segmentation; deep regression; saliency analysis; uncertainty quantification; UK Biobank; Medical Informatics; Medicinsk informatik;

   Sammanfattning : Large-scale studies, such as UK Biobank, acquire medical imaging data for thousands of participants. With magnetic resonance imaging (MRI), comprehensive representations of human anatomy can be provided for non-invasive assessments of health-related conditions, body composition, organ volumes, and more.

   Författare :Yevgen Ryeznik; Warwick Tucker; Andrew Hooker; Franz König; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; optimal designs; optimal adaptive designs; randomization in clinical trials; restricted randomization; adaptive randomization; unequal cost; allocation ratio preserving randomization procedures; heterogeneous costs; multi-arm clinical trials; randomization-based inference; unequal allocation; Tillämpad matematik och statistik; Applied Mathematics and Statistics;

   Sammanfattning : In this Ph.D. thesis, we investigate how to optimize the design of clinical trials by constructing optimal adaptive designs, and how to implement the design by adaptive randomization. LÄS MER

4. 23. Cross-Layer Optimization of Voice over IP in Wireless Mesh Networks

   Författare :Peter Dely; Andreas Kassler; Dirk Staehle; Karlstads universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Datavetenskap; Computer Science;

   Sammanfattning : Wireless Mesh Networks (WMNs) have emerged as a promising network technology, which combines the benefits of cellular networks and Wireless Local Area Networks (WLANs). In a WMN mesh routers wirelessly relay traffic on behalf of other mesh routers or clients and thereby provide coverage areas comparable to cellular networks, while having the low complexity and low costs of WLANs.

5. 24. Analysis of Dispersion Effects in Unreplicated Factorial Designs

   Författare :Kerstin Wiklander; Göteborgs universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; dispersion effects; location effects; two-level factorial experiment; fractional designs; Hadamard products; fractional designs;

   Sammanfattning : Methods for estimating and testing hypotheses of dispersion effects in two-level unreplicated factorial designs are studied. Under a particular = normal model, some linear combinations of the response variables are constructed in order to make a simple inference. LÄS MER

7. 25. Essays on Behavioral and Experimental Economics – Cooperation, Emotions and Health

   Författare :Emil Persson; Göteborgs universitet; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Public goods; Minimum level; Voting; Framing; Emotion; Psychological game; Physician behavior; Incentives; Risk; Experiment;

   Sammanfattning : This thesis consists of four self-contained papers that explore issues in human behavior and their implications for policy design. The main method used in all four papers consists of lab experiments, a method that facilitates both variation in key institutional features to allow causal inference and analysis of sharp theoretical predictions in a clean environment.
