  1. 21. Optimal Design of District Energy Systems: a Multi-Objective Approach

    Författare :Cong Wang; Ivo Martinac; Birgit Müller; KTH; []
    Nyckelord :HUMANIORA; HUMANITIES; multi-objective optimization; robust design optimization; district energy; Civil and Architectural Engineering; Byggvetenskap;

    Sammanfattning : The aim of this thesis is to develop a holistic approach to the optimal design of energy systems for building clusters or districts. The emerging Albano university campus, which is planned to be a vivid example of sustainable urban development, is used as a case study through collaboration with the property owners, Akademiska Hus and Svenska Bostäder.

  3. 22. On Specifying and Estimating Economic Growth as a Spatial Process : Convergence, Inequality, and Migration

    Författare :Martin E. Gustafsson; Roger Bivand; Uppsala universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Social and economic geography; Economic geography; economic growth; regional convergence; migration; spatial statistics; spatially correlated errors; geographical dependence; Kulturgeografi; Human geography; Kulturgeografi; kulturgeografi; Social and Economic Geography;

    Sammanfattning : This thesis includes three self-contained papers. The first paper considers the effect of geographically dependent observations on cross-sectional growth convergence and proposes a way of decomposing the level of technology taking into account geographical variation in growth rates.

  4. 23. Models and Methods for Random Fields in Spatial Statistics with Computational Efficiency from Markov Properties

    Författare :David Bolin; Matematisk statistik; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; random fields; Gaussian Markov random fields; Matérn covariances; stochastic partial differential equations; Computational efficiency;

    Sammanfattning : The focus of this work is on the development of new random field models and methods suitable for the analysis of large environmental data sets. A large part is devoted to a number of extensions to the newly proposed Stochastic Partial Differential Equation (SPDE) approach for representing Gaussian fields using Gaussian Markov Random Fields (GMRFs).

  5. 24. Incentives and Norms in Social Insurance: Applications, Identification and Inference

    Författare :Johan Vikström; Per Johansson; John Ham; Uppsala universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Economics; Nationalekonomi; nationalekonomi; Economics;

    Sammanfattning : This thesis consists of five self-contained essays. Essay 1: (with Patrik Hesselius and Per Johansson) This essay tests if social work norms are important for work absence using a large scale randomised experiment. LÄS MER

  7. 25. Spatial variability of geogenic contaminants in drinking water sources : Insights into hydrogeological controls, geospatial data for safe water supply and groundwater resource management

    Författare :J. Ijumulana; Prosun Bhattacharya; Felix Mtalo; Steve W. Lyon; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Drinking water; geogenic contaminants; potentially toxic elements; fluoride; spatial analysis; spatial variability; Tanzania; Land and Water Resources Engineering; Mark- och vattenteknik;

    Sammanfattning : The presence of geogenic contaminants in drinking water is a major health concern in many parts of the world. The interaction of groundwater with different rock types and sediments in the natural geochemical environment play an important role in controlling their mobility. LÄS MER
