1. The microdosimetric variance-covariance method used for beam quality characterization in radiation protection and radiation therapy
Sammanfattning : Radiation quality is described by the RBE (relative biological effectiveness) that varies with the ionizing ability of the radiation. Microdosimetric quantities describe distributions of energy imparted to small volumes and can be related to RBE. LÄS MER
2. Numerical Algorithms for Optimization Problems in Genetical Analysis
Sammanfattning : The focus of this thesis is on numerical algorithms for efficient solution of QTL analysis problem in genetics.Firstly, we consider QTL mapping problems where a standard least-squares model is used for computing the model fit. LÄS MER
3. Towards nanodosimetry: therapeutic radiation measurements using the variance method
Sammanfattning : Understanding how radiation damage occurs in human tissue seems to lie in the knowledge of energy depositions in DNA-size volumes, with diameters typically around a few nanometres. In such small volumes the energy transfers are stochastic and described using distributions of events along a particle track and relevant mean values. LÄS MER
4. On Optimisation and Design of Geodetic Networks
Sammanfattning : Optimisation of a geodetic network is performed to provide its pre-set quality requirements. Today, this procedure is almost run with the aid of developed analytical approaches, where the human intervention in the process cycle is limited to defining the criteria. LÄS MER
