1. Evaluation, Experience and Potential of Gas Turbine Based Cycles with Humidification
Abstract : Gas turbines, in simple and combined cycle, are common and economically profitable on the power generating market today. Several new cycles have been proposed as future competing technologies, but all studies about these cycles have, so far, been paperwork. READ MORE

2. Polychlorinated biphenyls and their metabolites in human blood : Method development, identification and quantification
Abstract : PCBs are well known environmental pollutants. They are also precursors to metabolites, as the hydroxy-PCBs and the methylsulfonyl-PCBs. This thesis presents a validated methodology for analysis of PCB metabolites and a structural identification of 38 hydroxy-PCBs in human blood. READ MORE

3. Parallel computing in model-based process engineering
Abstract : Chemical processes are usually expensive to run. To optimise a process, we need to know how the process behaves, and this is usually accomplished by studying the process experimentally. However, experiments are very expensive, particularly if an existing plant has to shut down normal operation to conduct an experiment. READ MORE

4. Automatic Synthesis of Sequential Control Schemes
Abstract : Of all hard- and software developed for industrial control purposes, the majority is devoted to sequential, or binary valued, control and only a minor part to classical linear control. Typically, the sequential parts of the controller are invoked during startup and shut-down to bring the system into its normal operating region and into some safe standby region, respectively.

5. Development of an integrated neutronic/thermal-hydraulic tool for estimating fluctuations in PWRs
Abstract : Monitoring and diagnostics of a reactor core at a given state is very important for detecting potential problems and anomalies at an early stage. Several methods exist for these purposes, but the majority of them require a disruption of the plant operation, e.g. by shut-down or by perturbation of the system. READ MORE
