1. Phase Modulation Techniques for On-Off Keying in Optical Fibre Transmission
Abstract : Increasing the channel bit rate is an efficient way to upgrade traffic capacity in installed transmission links. At bit rates of the order of 40 Gb/s, on-off keying (OOK) transmission becomes severely impaired by non-linear effects especially Intra-channel Four-Wave Mixing (IFWM) which limit the power at which the signal can be transmitted, and ultimately the transmission distance.

2. Drug treatment in children with focus on off-label drug use
Abstract : There is a lack of paediatric documentation concerning efficacy and safety of many drugs, which contribute to drug use outside the terms of the product license (off-label). In the present thesis, four studies (I-IV), using different settings and design to evaluate pharmacological treatment in children, with focus on off-label drug use, is presented. READ MORE

3. Blast furnace coke properties and the influence on off-gas dust
Abstract : In blast furnace ironmaking, efforts are made to decrease the coke consumption mainly by increasing the pulverized coal injection rate. This will cause changes in in-furnace reduction conditions, burden distribution and demands on raw material strength, etc. READ MORE

4. Understanding the Influence of Wood Extractives on Off-Gassing during Storage of Wood Pellets
Abstract : Wood pellets have become a solid biomass fuel of choice because they are a standardized product with known quality properties. However, the self-heating and off-gassing tendencies during storage of wood pellets threatens the consistency of the pellets’ quality properties. READ MORE

5. Feed-forward Control and Dynamic Modelling in Temperature Control of Buildings
Abstract : This thesis is mainly about the investigations of different control strategies (and in particular feed-forward) in order to improve indoor climate and/or save energy in buildings. One part of the thesis deals with different ways to obtain dynamic models for climate systems in buildings. READ MORE
