6. Experiments and Predictions of Heat Transfer Characteristics in Circulating Fluidized Bed Boilders
Sammanfattning : This thesis presents experiments and predictions of heat transfer characteristics in circulating fluidized bed boilers. The boiler used for the experiments has a maximum load of 12 MWth, and the dimensions of the combustion chamber are 1.4 m x 1.7 m x 1 3. LÄS MER
7. Robust inference of gene regulatory networks : System properties, variable selection, subnetworks, and design of experiments
Sammanfattning : In this thesis, inference of biological networks from in vivo data generated by perturbation experiments is considered, i.e. deduction of causal interactions that exist among the observed variables. Knowledge of such regulatory influences is essential in biology. LÄS MER
8. Human Behaviour in Social-Ecological Systems : Insights from economic experiments and agent-based modelling
Sammanfattning : Progress towards sustainability requires changes in our individual and collective behaviour. Yet, our fundamental understanding of behaviour in relation to environmental change remains severely limited. LÄS MER
9. Flow Boiling Heat Transfer and Pressure Drop. Experiments and Model Development for Complex Geometries
Sammanfattning : Two very different evaporator geometries, a dimple plate and a herringbone microfin tube, have been studied. Heat transfer and pressure drop for both pure refrigerants and refrigerant mixtures have been determined experimentally. LÄS MER
10. Optical sensors in drinking water production : Towards automated process control in relation to natural organic matter
Sammanfattning : Access to safe and clean drinking water is a basic human right (A/RES/64/292). In Sweden, large drinking water treatment plants use mainly surface water as water source. The long-term trend of increasing natural organic matter (NOM) in boreal and north European surface waters negatively affects the overall performance of the treatment processes. LÄS MER
