21. The Art of Modelling Oscillations and Feedback across Biological Scales
Sammanfattning : This thesis consists of four papers in the field of mathematical biology. All papers aim to advance our understanding of biological systems through the development and application of innovative mathematical models. LÄS MER
22. Closed-Loop Combustion Control of a Multi Cylinder HCCI Engine using Variable Compression Ratio and Fast Thermal Management
Sammanfattning : The current Spark Ignited (SI) engine equipped with three-way catalyst offers low emissions, but has low efficiency at part load, which results in unnecessarily high CO2 emissions. The Compression Ignited (CI) engines have higher efficiency and hence lower CO2 emissions, but suffer from higher Nitrogen Oxide (NOx) and Particulate Matter (PM) emissions, and no three-way catalyst can be used.

23. FGFs and Wnts in pancreatic growth and β-cell function
Sammanfattning : Mesenchymal-epithelial interactions are pivotal for proper pancreatic growth and development. The pancreatic progenitor cells present in the early pancreatic anlagen proliferate and eventually give rise to all pancreatic cell types. LÄS MER
24. Feedback Control of Spatially Evolving Flows
Sammanfattning : In this thesis we apply linear feedback control to spatially evolving flows in order to minimize disturbance growth. The dynamics is assumed to be described by the linearized Navier--Stokes equations. Actuators and sensor are designed and a Kalman filtering technique is used to reconstruct the unknown flow state from noisy measurements. LÄS MER
25. On Tailbiting Codes from Convolutional Codes
Sammanfattning : Tailbiting is a method to terminate convolutional codes into block codes. We call these block codes tailbiting codes. This thesis focuses on the encoding of tailbiting codes. The tailbiting method is carefully investigated. LÄS MER
