Mixing patterns in Rushton-turbine-agitated reactors

This Ph.D. Thesis concerns the study of mixing in Rushton turbine agitated reactors. In industrial (bio)reactors, mixing is recognised as a limiting factor that significantly affects the performance of the process. This limitation has motivated the present study. It is first shown how planar laser-induced fluorescence (PLIF) can be used to investigate mixing in a model reactor. The principles of

Heat transfer enhancement in square ducts with V-shaped ribs of various angles

Experimental studies have revealed that both downstream and upstream pointing V-shaped ribs result in better heat transfer enhancement than transverse straight ribs of the same geometry. Secondary flows induced by the angled ribs are believed to be responsible for this higher heat transfer enhancement. Further investigations are needed to understand this. In the present study, the heat and fluid f

Challenges in the Solution of the Transfer Equation in Multi-D Hydrodynamical Model Atmospheres for Cool Stars

My talk is intended to stimulate discussions about methods in radiativetransfer for hydrodynamical model atmospheres of late-type stars. I willpresent a number a number of inherent problems, show how they arepresently tackled (if so), and ask for ideas for more efficient approaches.

Multiband diversity antenna performance study for mobile phones

Spatial diversity is a popular multiple antenna system technique, due to simplicity in implementation. However, its application has thus far been limited to systems where the electrical separation between adjacent antennas typically exceeds half a wavelength. This is because a more compact design induces higher antenna correlation and impedance mismatch, which results in lower diversity gains. In

Beta-Glycosidases from Hyperthermophiles as Biocatalysts

The thesis concerns glycosyl transfer with use of b-glycosidases, most of them from hyperthermophilic organisms. Both optimisation of the reaction conditions and protein engineering in terms of site-directed mutagenesis were used to improve b-glycosidase-catalysed reactions. The first part of the work deals with conversion of lactose into valuable products such as galacto-oligosaccharides (GOS) an

The capital cost of holding inventory - A real options approach

This thesis is based on three scientific papers dealing with costs and financial risks associated with keeping stock. Reasonable cost parameters are important to implement an effective inventory control system, which in turn is one of the key activities in logistics management. All three papers consider a single-level inventory system. Single-period, multi-period as well as continuous review syste
