1. 21. Cooperative Communications : Link Reliability and Power Efficiency

   Författare :Tafzeel ur Rehman Ahsin; Ben Slimane; Xavier Lagrange; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Cooperative Communications; Link Reliability; Power Efficiency; Energy Efficiency; Network Coding; Cooperative Relaying; SRA - ICT; SRA - Informations- och kommunikationsteknik;

   Sammanfattning : Demand for high data rates is increasing rapidly for the future wireless generations, due to the requirement ofubiquitous coverage for wireless broadband services. More base stations are needed to deliver these services, in order tocope with the increased capacity demand and inherent unreliable nature of wireless medium. LÄS MER

   Sammanfattning : The Severan age has become known as a time when Syrian empresses brought eastern influences to Rome and transformed the stable principate into an absolutist state ready for the dominate. Every tie to the old principate was broken in a conscious attempt to change the fundamental structure of society. LÄS MER

4. 23. Järnålderns Skåne : samhälle, centra och regioner

   Nyckelord :HUMANIORA; HUMANITIES; Iron Age; Ancient history; centrality; Antikens och forntidens historia; communication; defence; long-distance trade; specialized craft; king; elite; cheiftain; social structure; central place; region; power; Scania; hierarchy; Archaeology; Arkeologi;

   Sammanfattning : The first purpose of this dissertation is to describe and discuss the development of the Iron Age society in Scania. The second purpose is to discuss the relations between Scania and the neighbouring areas. The Iron Age society was hierarchical and ruled by different types of leaders, usually cheiftains or kings.

5. 24. Structure and dynamics of complex materials in the water-poor regime

   Författare :Sanna Gustavsson; Fysikalisk kemi; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Hydration; cellulose; dissolution; sugar surfactant; hydrated crystals; structure; dynamics; phase diagram; fuel cell; pulsed-field-gradient PFG spin-echo NMR; Polarization Transfer solid state NMR; PXRD; GVS; TGA; amphiphilic;

   Sammanfattning : In the solid state, molecules are normally ordered in a specific structure. With time, and as a result of influence from the surroundings, solid materials can change their molecular and/or crystal structure and, as a consequence, obtain completely different properties. Water is particularly important in this respect. LÄS MER

7. 25. Modeling of Wind Turbines for Power System Studies

   Författare :Tomas Petru; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; flicker; fault response; power quality; wind turbine; power system stability; measurements; prediction; verification; grid simulation; modeling;

   Sammanfattning : The power quality impact of wind turbines on the electric grid and the response of the wind turbines to faults in the electric grid are investigated in this thesis. A detailed model of a stall-regulated, fixed-speed wind turbine system capable of predicting the flicker impact on the connected grid is presented and compared with field measurements. LÄS MER
