1. Hormonal regulation of liver and tumor growth
Sammanfattning : The aims of this thesis were to investigate the regulatory functions of interleukin-6 (IL-6) and tumor necrosis factor-a (TNF-a) on liver growth, and the importance of hepatocyte growth factor (HGF) and the HGF receptor (Met) for growth of mesenchyme-derived tumors. The studies on different types of liver growth, measured as weight, DNA and protein content, and DNA synthesis, were performed on mice lacking the IL-6 or the TNF receptor-1 gene back-crossed to the C57bl/6 strain.

Sammanfattning : .... LÄS MER
3. Truncated Signed Distance Fields Applied To Robotics
Sammanfattning : This thesis is concerned with topics related to dense mapping of large scale three-dimensional spaces. In particular, the motivating scenario of this work is one in which a mobile robot with limited computational resources explores an unknown environment using a depth-camera. LÄS MER
4. Estimators of semiparametric truncated and censored regression models
Sammanfattning : This thesis contributes in several ways to the existing knowledge on estimation of truncated, censored, and left truncated right censored (LTRC) regression models. Three new semiparametric estimators are proposed, allowing for asymmetric error distributions. LÄS MER
5. Statistical Properties of Preliminary Test Estimators
Sammanfattning : This thesis investigates the statistical properties of preliminary test estimators of linear models with normally distributed errors. Specifically, we derive exact expressions for the mean, variance and quadratic risk (i.e. the Mean Square Error) of estimators whose form are determined by the outcome of a statistical test. LÄS MER
