  2. 21. A study on the deployment and cooperative operation of ultra-dense networks

    Author : Yanpeng Yang; Ki Won Sung; Jens Zander; Yngve Selen; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Informations- och kommunikationsteknik; Information and Communication Technology;

    Abstract : The traffic volume in wireless communication has grown dramatically in the last decade and is predicted to keep increasing in the future. In this thesis, we focus on the densification dimension for capacity improvement, which has been proved to be the most effective in the past. READ MORE

  4. 22. Surface-Densified Wood : From Laboratory-Scale Research Towards a Competitive Product

    Author : Benedikt Neyses; Dick Sandberg; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Träteknik; Wood Science and Engineering;

    Abstract : For many decades, humans have been consuming more resources than the world has to offer in the long run. Increasing the use of renewable materials, such as wood, is essential if we are to achieve a sustainable use of the resources available to us. READ MORE

  5. 23. Compact sprawl : Exploring public open space and contradictions in urban density

    Author : Alexander Ståhle; Lars Marcus; Michael Batty; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Spatial morphology; Urban design; Public open space; Urban density; Landscape planning; Architecture; Arkitektur;

    Abstract : Twentieth century urbanization has left a tremendous footprint on the globe. It is generally speaking a spread out fragmented suburban and exurban landscape continuously growing according to what has been called sprawl-like development, increasing energy and automobile dependency, challenging urban sustainability.

  6. 24. Spark Plasma Sintering of Si3N4-based Ceramics : Sintering mechanism-Tailoring microstructure-Evaluationg properties

    Author : Hong Peng; Zhijian (James) Shen; Mats Nygren; Michael J. Hoffmann; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; spark plasma sintering; silicon nitride ceramics; grain growth kinetic; superplasiticity; liqiud phase sintering; Chemistry; Kemi;

    Abstract : Spark Plasma Sintering (SPS) is a promising rapid consolidation technique that allows a better understanding and manipulating of sintering kinetics and therefore makes it possible to obtain Si3N4-based ceramics with tailored microstructures, consisting of grains with either equiaxed or elongated morphology. The presence of an extra liquid phase is necessary for forming tough interlocking microstructures in Yb/Y-stabilised α-sialon by HP. READ MORE

  7. 25. Engineering of Pharmaceutical Particles : Modulation of Particle Structural Properties, Solid-State Stability and Tabletting Behaviour by the Drying Process

    Author : Jonas Berggren; Göran Alderborn; Graham Buckton; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Pharmaceutics; particle engineering; microcrystalline cellulose pellets; intragranular porosity; convective drying; tabletting behaviour; spray-dried composite particles; amorphous lactose; PVP; heat and moisture-induced crystallisation; glass transition temperature; Galenisk farmaci; Pharmaceutics; Galenisk farmaci; galenisk farmaci; Pharmaceutics;

    Abstract : Relationships between stresses during the drying process, particle structural and functional properties, and particle engineering by the drying process were addressed in this thesis. In the first part, the importance of the drying phase and the effect of the drying rate on the intragranular porosity of microcrystalline cellulose pellets were investigated. READ MORE
