1. Type Ia Supernovae : Homogeneity and Diversity
Sammanfattning : The use of type Ia supernovae as distance estimators has shown that about 75% of the energy content of the universe has a negative equation of state parameter and thus, drives the acceleration of the universe. Constraining the exact nature of this energy is one of the main goals in cosmology. LÄS MER
2. Testing Homogeneity and Unit Root Restrictions in Panels
Sammanfattning : This thesis is divided into two distinct parts. The first part contains three chapters, co-authored with Joakim Westerlund, that deal with the analysis of unit root testing, and the second part consists of two chapters on slope homogeneity testing. LÄS MER
3. An Experimental Study of Liquid Steel Sampling
Sammanfattning : Sampling of liquid steel to control the steel making process is very important in the steel industry. However, there are numerous types of disposable samplers and no united standard for sampling. The goal in this study is to investigate the effect of slag protection type and sample geometry on sampling parameters and sample homogeneity. LÄS MER
4. An Experimental Study of a Liquid Steel Sampling Process
Sammanfattning : During the steelmaking process samples are taken from the liquid steel, mainly to assess the chemical composition of the steel. Recently, methods for rapid determination of inclusion characteristics (size and composition) have progressed to the level where they can be implemented in process control. LÄS MER
5. From Lab to Chip – and back : Polymer microfluidic systems for sample handling in point-of-care diagnostics
Sammanfattning : This thesis contributes to the development of Lab-on-a-Chip systems that enables reliable, rapid medical diagnostics at the point-of-care. These contributions are focused on microfluidic Lab-on-a-Chip systems for sepsis diagnosis, autonomous sample-to-answer tests, and dried blood spot sampling. LÄS MER
