4. 2. Aspects on Interference and Diversity in Wireless Networks

   Author : Fredrik Florén; Institutionen för elektro- och informationsteknik; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Telekommunikationsteknik; Telecommunication engineering; Elektronik och elektroteknik; Electronics and Electrical technology; feedback; multiuser communication; diversity; throughput; packet radio networks; Interference; frequency hop communication;

   Abstract : This thesis deals with two topics in wireless communications: interference between frequency-hopping (FH) networks, and multiuser diversity. The work on FH treats a system where FH is used to provide simultaneous access to the channel for multiple uncoordinated wireless networks. READ MORE

5. 3. Brazilian public protection regulations and the preservation of ecosystem services and biodiversity

   Author : Flavio L. M. Freitas; Ulla Mörtberg; Jan Börner; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Brazil; Native vegetation; forest conservation; Brazilian Forest Act; Protected areas; Ecosystem services; Biodiversity; Land and Water Resources Engineering; Mark- och vattenteknik;

   Abstract : Brazil is significant for sustaining ecosystems services and biodiversity of global importance. However, the expansion of forestry and agriculture to supply national and international markets often results in loss of ecosystem services and biodiversity. Public protection regulations play a crucial role in setting limits for agricultural expansion. READ MORE

   Abstract : In the present thesis, I investigated the spatial structure of genetic and morphometric variation in the widespread wind-pollinated shrub Corylus avellana (L.) Betulaceae, hazel, and related the variation to geographic distribution and different spatial scales. READ MORE

7. 5. A Methodology to Control the Microstructure of Plasma Sprayed Coatings

   Author : Martin Friis; Materialteknik; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; materialteknik; Materiallära; Process map; Plasma spraying; process window; Thermal Barrier Coating; Zirconia; DPV2000; particle temperature; Material technology; particle velocity;

   Abstract : The aim of this thesis is to enhance the overall understanding of the plasma spray process and increase control and reproducibility of the coating properties. This was performed by establishment of relationships between controllable process parameters, in-flight properties of the injected particles (velocity and temperature), and microstructure properties.
