6. Skin hydration - How water and osmolytes influence biophysical properties of stratum corneum
Sammanfattning : The outermost layer of skin (i.e., the stratum corneum, SC) is the interface that separates the water-rich inside of the body from the relatively dry external environment. SC forms an effective permeability barrier, which has to be overcome in transdermal drug delivery. LÄS MER
7. Numerical solution of the Fokker–Planck approximation of the chemical master equation
Sammanfattning : The chemical master equation (CME) describes the probability for the discrete molecular copy numbers that define the state of a chemical system. Each molecular species in the chemical model adds a dimension to the state space. LÄS MER
8. Thermal Modelling of Small Cage Induction Motors
Sammanfattning : The loadability of electric machines is above all determined by temperature limits. In this work, thermal network models, suitable for totally enclosed fan cooled (TEFC) induction motors, are used to predict the machine temperatures. LÄS MER
9. On Real-Time Optimization using Extremum Seeking Control and Economic Model Predictive Control : With Applications to Bioreactors and Paper Machines
Sammanfattning : Process optimization is used to improve the utility and the economic performance of industrial processes, and is as such central in most automation strategies. In this thesis, two feedback-based methods for online process optimization are considered: Extremum seeking control (ESC), a classic model-free method used for steady-state optimization which dates back to the early 1900's, and economic model predictive control (EMPC), a more recent method which utilizes a model to dynamically optimize the closed-loop process economics in real time.

10. Fingerprints of light-induced molecular transients : from quantum chemical models of ultrafast x-ray spectroscopy
Sammanfattning : Absorption of sunlight generates renewable electricity and powers the growth of plants, but also causes severe damage both to synthetic materials and biological tissue. The wildly varying outcomes of these light-induced processes are ultimately determined by much slighter differences in their underlying reaction pathways, induced by the transient properties of short-lived and miniscule molecules; a powerful approach to their detection and characterization is offered by ultrafast x-ray spectroscopy, with identification of spectral fingerprints and further guidance from quantum chemical models.
