1. Some Aspects of Propensity Score-based Estimators for Causal Inference
Sammanfattning : This thesis consists of four papers that are related to commonly used propensity score-based estimators for average causal effects.The first paper starts with the observation that researchers often have access to data containing lots of covariates that are correlated. LÄS MER
2. Advanced MRI Data Processing
Sammanfattning : Magnetic resonance imaging (MRI) is a very versatile imaging modality which can be used to acquire several different types of images. Some examples include anatomical images, images showing local brain activation and images depicting different types of pathologies. LÄS MER
3. Four Essays on Building Conditional Correlation GARCH Models
Sammanfattning : This thesis consists of four research papers. The main focus is on building the multivariate Conditional Correlation (CC-) GARCH models. In particular, emphasis lies on considering an extension of CC-GARCH models that allow for interactions or causality in conditional variances. LÄS MER
4. Thermal crack estimation in early age concrete : models and methods for practical application
Sammanfattning : Control of thermal cracking in young concrete is of great importance to ensure a desired service life time and function of a structure. Making reliable thermal stress estimations, and thereby conclusions about cracking risks, involves advanced modelling of material properties and structural restraint. LÄS MER
5. Digital block transmission and time-of-flight estimation : receiver design and performance analysis
Sammanfattning : This thesis is concerned with signal processing aspects of digital block transmission and time-of-flight estimation. Receivers are derived and analysed based on the assumption that the received signals have been corrupted with additive Gaussian noise and linear distortion. LÄS MER
