11. Modeling and Simulation of a Multi Phase Semi-batch Reactor
Abstract : The operation of an industrial semi-batch reactor is modeled and the flow of one reactant is investigated. In the reactor a strongly exothermic polymerization reaction takes place followed by a slightly exothermic reaction, and the objective is to minimize the duration of the operation of the process.

13. Development of a protein-free fed-batch process for NS0 cells: studies on regulation of proliferation
Abstract : The overall objective of this study was to investigate how NS0 cell proliferation is regulated in protein-free media. The hypothesis was that during the adaptation to growth factor-free media, animal cell lines start to produce their own autocrine growth factors to support proliferation, and after some time in a culture the effects of these factors are lost which results in cessation of proliferation.

14. Large-scale Bioreactor Phenomena and Characteristics; Effects on E.coli fed batch fermentations on 30m3 scale
Abstract : Due to economical and practical limitations the fluiddynamics and mass transport properties are less optimal inlarge-scale bioreactors compared to lab-scale bioreactors. Incombination with the microbial reaction rates this creates amuch more dynamic environment for cells cultivated inlarge-scale bioreactors compared to lab-scale bioreactors. READ MORE

15. Probing Control : Analysis and Design with Application to Fed-Batch Bioreactors
Abstract : In most control problems the objective is to control the output at a desired value in spite of disturbances. In some cases, the best setpoint is not known a priori and it should be found online to optimize the process performance. This thesis examines a probing strategy that can be applied for this class of problems. READ MORE
