  2. 1. Networks of urban interaction - Growth and centrality in the complex geography of urban activity

    Author : Alexander Hellervik; Chalmers tekniska högskola; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; accessibility; power law; urban activity; centrality; urban growth; transport infrastructure; spatial interaction; complex networks; Zipf’s law;

    Abstract : How cities and regions grow and decline depend on technological, social and economic factors. Understanding the interplay of these forces is central in research efforts aiming to improve urban and transport planning. READ MORE

  4. 2. Exploring Massive Volunteered Geographic Information for Geographic Knowledge Discovery

    Author : Jia Tao; Jiang Bin; Harrie Lars; KTH; []
    Keywords : VGI; OSM; Geographic knowledge discovery; Zipf’s law; Urban sprawl;

    Abstract : Conventionally geographic data produced and disseminated by the national mapping agencies are used for studying various urban issues. These data are not commonly available or accessible, but also are criticized for being expensive. However, this trend is changing along with the rise of Volunteered Geographic Information (VGI).

  5. 3. Growth, Factor Shares, and Factor Prices

    Author : Julius Probst; Ekonomisk-historiska institutionen; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; secular stagnation; labor share; imputations; asset prices; real interest rate; Zipf s law;

    Abstract : This dissertation is a study in empirical macroeconomic history. The first two papers concern themselves with the functional distribution of income. The third paper is an examination of global real interest rates, and the final paper examines city growth in Sweden over the last two hundred years. READ MORE

  6. 4. Geospatial Knowledge Discovery using Volunteered Geographic Information : a Complex System Perspective

    Author : Tao Jia; Bin Jiang; Yifang Ban; Itzhak Benenson; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; knowledge discovery; urban systems; complex system; VGI; OSM; GPS tracking dataset; scaling; heavy-tailed distribution detection; urban sprawl; Zipf’s law; human activity mobility patterns; agent-based modeling; complex network.;

    Abstract : The continuous progression of urbanization has resulted in an increasing number of people living in cities or towns. In parallel, advancements in technologies, such as the Internet, telecommunications, and transportation, have allowed for better connectivity among people. READ MORE

  7. 5. Simulation-based Optimization and Decision Making with Imperfect Information

    Author : Farzad Kamrani; Rassul Ayani; Stephen John Turner; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Simulation-based Optimization; UAV Path Planning; Business Process Optimization;

    Abstract : The purpose of this work is to provide simulation-based support for making optimal (or near-optimal) decisions in situations where decision makers are faced with imperfect information. We develop several novel techniques and algorithms for simulation-based optimization and decision support and apply them to two categories of problems: (i) Unmanned Aerial Vehicle (UAV) path planning in search operations, and; (ii) optimization of business process models.
