    Abstract : This doctoral thesis combines complexity science and economic geography in order to explore bottom-up, self-organizing principles within urban economies, in particular in relation to the flow of information and knowledge between people. The thesis consists of a kappa that covers the general theoretical framework and four papers. READ MORE

  5. 3. CVD Growth of Silicon Carbide for High Frequency Applications

    Author : Urban Forsberg; Erik Janzén; Anne Henry; Christian Brylinski; Linköpings universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Material physics with surface physics; Materialfysik med ytfysik;

    Abstract : Silicon Carbide (SiC) is an important wide band gap semiconductor with outstanding electronic properties. With figures of merit far better than silicon, SiC is believed to replace and outcompete silicon in many applications using high frequencies, high voltage and high temperatures. READ MORE

  6. 4. The Principle of Scaling of Geographic Space and its Application in Urban Studies

    Author : Xintao Liu; Bin Jiang; Yifang Ban; Meng Liqiu; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; geographic space; scaling; GIScience; VGI; OSM; heavy-tailed distribution; the head tail division rule; space syntax; nature street; urban sprawl; floating car data; hierarchical spatial structure;

    Abstract : Geographic space is the large-scale and continuous space that encircles the earth and in which human activities occur. The study of geographic space has drawn attention in many different fields and has been applied in a variety of studies, including those on cognition, urban planning and navigation systems.
