  1. 21. Inferring Land Use from Remote Sensing Imagery : A context-based approach

    Författare :Michael Meinild Nielsen; Bo Malmberg; Anders Wästfelt; Douglas A. Stow; Stockholms universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; land use; remote sensing; urban remote sensing; image analysis; segmentation; spatial context; land cover; land cover configuration; farming types; bark beetle; dead trees; forest inventory; kulturgeografi; Human Geography;

    Sammanfattning : This doctoral thesis investigates the potential of classification methods based on spatial context to infer specific forms of land use from remote sensing data. The problem is that some types of land use are characterized by a complex configuration of land covers that traditional per-pixel based methods have problems classifying due to spectral heterogeneity.

  3. 22. Revisiting the urban block in the light of climate change : A case study of Budapest

    Författare :Csilla V Gál; Peter Land; []
    Nyckelord :HUMANIORA; HUMANITIES; NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Since the beginning of the twentieth century, the urban block configuration of free-standing buildings has been deemed superior to other built forms, as it provided the necessities of modern healthy living: sunlight and fresh air. In light of climate change, the dissertation aims to reevaluate these long held beliefs and to reintroduce microclimate as an urban design consideration. LÄS MER

  4. 23. Quantification of mineral weathering rates in sulfidic mine tailings under water-saturated conditions

    Författare :Magdalena Gleisner; Docent Roger Herbert; Professor Emeritus Rolf Hallberg; Dr. Magnus Land; Professor Patrick Crill; Mats Åström; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; mine tailings; pyrite; sulfides; weathering; oxygen availability; Acidithiobacillus ferrooxidans; Earth sciences; Geovetenskap;

    Sammanfattning : Tailings are a fine-grained waste product produced during the metal recovery process. Tailings consist mostly of different silicates but also sulfides (e.g. pyrite), since 100 % metal recovery is not possible. LÄS MER

  5. 24. Oxidative stress and alterations in the mammalian iron metabolism : A study on iron, inflammation, oxidative stress and neurodegeneration

    Författare :Jonas Hälldin; Tiit Land; Paolo Arosio; Stockholms universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Neurochemistry; Neurokemi; Neurochemistry and Molecular Neurobiology; neurokemi med molekylär neurobiologi;

    Sammanfattning : Iron is essential for all living organisms, from bacteria to man for a broad variety of biological functions, including oxygen transport and DNA synthesis. However, iron can also be toxic, due to its involvement in the formation of highly reactive oxygen species through Fenton chemistry. LÄS MER

  7. 25. Key Elements of Software Product Integration Processes

    Författare :Stig Larsson; Ivica Crnkovic; Fredrik Ekdahl; Rikard Land; Paul Grünbacher; Mälardalens högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; product integration; software development; process improvement; Software engineering; Programvaruteknik; Computer Science; datavetenskap;

    Sammanfattning : The product integration is a particularly critical phase of the software product development process as many problems originating from earlier phases become visible in this phase. Problems in product integration result in delays and rework. LÄS MER
