11. Strategic groundwater protection
Sammanfattning : Groundwater is an undervalued natural resource that isexperiencing a large number of threats to both its quantity andquality. Different types of land-use activities releasepotentially harmful substances that may be transported down tothe groundwater and have a negative impact on its quality. LÄS MER
12. Biodiversity Protection in an Aspiring Carbon-Neutral Society : A Legal Study on the Relationship between Renewable Energy and Biodiversity in a European Union Context
Sammanfattning : There is a vision in the EU for a transition to a low carbon society, including a carbon-neutral energy system, containing a high share of renewable energy. However, this vision is not isolated from other political goals, such as halting the loss of biodiversity by 2020. LÄS MER
13. Nanocomposite films for corrosion protection
Sammanfattning : This thesis describes technical and scientific aspects of new types of composite films/coatings for corrosion protection of carbon steel, composite films with nanometer thickness consisting of mussel adhesive protein (Mefp‐1) and ceria nanoparticles, and polymeric composite coatings with micrometre thickness consisting of conducting polymer and ceria nanoparticles in a UV‐curing polyester acrylate (PEA) resin.The influence of microstructure on corrosion behaviour was studied for a Fe‐Cr‐V‐N alloy containing micro‐sized nitrides with different chemical composition spread in martensitic alloy matrix.

14. Differential Protection for Arbitrary Three-Phase Power Transformers
Sammanfattning : This thesis describes how to provide standardized, current based, differential protection for any three-phase power transformer, including phase-shifting transformers with variable phase angle shift and transformers of all construction types and internal on-load tap-changer configurations. The use of standard transformer differential protection for such applications is considered impossible in the protective relaying standards and practices currently applied. LÄS MER
15. Design and Analysis of Self-protection : Adaptive Security for Software Systems
Sammanfattning : Today's software landscape features a high degree of complexity, frequent changes in requirements and stakeholder goals, and uncertainty.Uncertainty and high complexity imply a threat landscape where cybersecurity attacks are a common occurrence while their consequences are often severe.
