11. Dynamic enforcement of decentralized security policies
Sammanfattning : This thesis explores defining security policies in a decentralized setting and dynamic methods of enforcing such policies. In a decentralized setting, principals are free to trust or distrust other principals. The key challenge is to provide possibilities for expressing and enforcing expressive decentralized policies.

12. Dynamic Sulfur Chemistry : Screening, Evaluation and Catalysis
Sammanfattning : This thesis deals with the design, formation and evaluation of dynamic systems constructed by means of sulfur-containing reversible reactions, in organic and aqueous media and under mild conditions. In a first part, the synthesis of thioglycoside derivatives, constituting the biologically relevant starting components of the dynamic systems, is described. LÄS MER
13. Diffusion of dynamic innovations : A case study of residential solar PV systems
Sammanfattning : In the literature on diffusion of innovations, it is widely known that the characteristics and socio-environmental settings of adopters do evolve in space and time. What about innovations themselves? During the diffusion process, don’t some innovations continuously alter in space and time? If so, how does the dynamic character of an innovation influence the diffusion process? In previous research, it has been often assumed that innovations do not continuously alter or get modified when diffusing from a source to potential adopters. LÄS MER
14. Dynamic and meta-dynamic recrystallization of Ni-based superalloy Haynes 282
Sammanfattning : Thermomechanical processes are a crucial manufacturing step because they can “reset” the microstructure, and set the starting point for all following steps. In turn, the microstructure can be used to tailor the mechanical properties of the material. LÄS MER
15. Modeling Complex Engines as Dynamic Powertrain Members
Sammanfattning : Engine modeling and simulation have been necessary tools for efficient product development in the automotive industry for some time. The scope of this work is novel engine models, tools, and methods for powertrain research and development. LÄS MER
