11. Modelling Chemical Reactions : Theoretical Investigations of Organic Rearrangement Reactions
Sammanfattning : Chemical reactions are ubiquitous and very important for life and many other processes taking place on earth. In both theoretical and experimental studies of reactivity a transition state is often used to rationalise the outcome of such studies. LÄS MER

13. Optimization of Low-Level Controllers and High-Level Polymer Grade Changes
Sammanfattning : Two design problems at different levels in the control hierarchy are considered; optimization of robust low-level controllers with constrained control signal activity and optimization of economical high-level polyethylene grade changes. As for the first design problem, a constraint on control signal activity due to measurement noise is presented and used when optimizing and comparing PI/PID controllers with measurement filters of different orders.

14. Prediction, modeling, and refinement of protein structure
Sammanfattning : Accurate predictions of protein structure are important for understanding many processes in cells. The interactions that govern protein folding and structure are complex, and still far from completely understood. However, progress is being made in many areas. Here, efforts to improve the overall quality of protein structure models are described. LÄS MER
15. Samnyttjad mark och urbana allmänningar : En fallstudie av skyfallsanpassning i Malmö och Köpenhamn
Sammanfattning : I avhandlingen analyseras möjligheter och hinder för samnyttjande av mark utifrån en fallstudie av skyfallsanpassning i Malmö och Köpenhamn. Som bakgrund står de klimatutmaningar i form av ökad framtida nederbörd och risk för översvämningar som städerna ställs inför, tillsammans med en tilltagande konkurrens om marken från allt fler behov.
