1. On Distribution Coefficients in Aquatic Systems
Abstract : In this thesis, different types of chemical and physical distribution coefficients are identified, examined and used to describe the fate and transport pathways of substances in aquatic systems.Observations from field experiments in streams with non-reactive and reactive tracers constituted the basis for development of an advection-dispersion model.

2. The material distribution method : analysis and acoustics applications
Abstract : For the purpose of numerically simulating continuum mechanical structures, different types of material may be represented by the extreme values {,1}, where 0.... READ MORE

3. Structural Models of Network Contacts Between Actors Governed by Activity and Attraction
Abstract : This thesis consists of five papers on the subject of statistical modeling of stochastic networks. The NG-model proposed in Paper I combines a block structure with parameters that capture the identities of vertices and thus the new approach stresses the concept of ego-nets, which describes the structure around identified vertices.

4. On Bicompositional Correlation
Abstract : A composition is a vector of positive components summing to a constant, usually taken to be 1. Hitherto the research on compositional correlation has mainly focused on the correlation between the components of composition. This thesis is concerned with modelling the correlation between two compositions. READ MORE

5. Fuel dispersion and bubble flow distribution in fluidized beds
Abstract : Fluidized bed technology is used for thermal conversion of solid fuels (combustion and gasification) and is especially suitable for conversion of low-rank fuels such as biomass and waste. The performance of fluidized bed units depends on the fuel mixing and fuel-gas contact. READ MORE
