  1. 6. Terrain Modelling with GIS for Tectonic Geomorphology : Numerical Methods and Applications

    Författare :Gyözö Jordan; Ulf Qvarfort; Tsehaie Woldai; Uppsala universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Environmental technology; digital elevation model; digital terrain modelling; GIS; morphometry; tectonic geomorphology; Miljöteknik; Environmental engineering; Miljöteknik;

    Sammanfattning : Analysis of digital elevation models (DEMs) by means of geomorphometry provides means of recognising fractures and characterising the morphotectonics of an area in a quantitative way. The objective of the thesis is to develop numerical methods and a consistent GIS methodology for tectonic geomorphology and apply it to test sites. LÄS MER

  3. 7. The development and implementation of software for palaeoenvironmental and palaeoclimatological research : the Bugs Coleopteran Ecology Package (BugsCEP)

    Författare :Philip Buckland; Roger Engelmark; Geoffrey Lemdahl; Paul Sinclair; Umeå universitet; []
    Nyckelord :HUMANIORA; HUMANITIES; Quaternary geology; environmental archaeology; quaternary science; Coleoptera; beetles; database; environmental reconstructions; climate reconstructions; software; Mutual Climatic Range; MCR; palaeoentomology; Kvartärgeologi; Archaeology; Arkeologi; Archaeology; arkeologi;

    Sammanfattning : This thesis documents the development and application of a unique database orientated software package, BugsCEP, for environmental and climatic reconstruction from fossil beetle (Coleoptera) assemblages. The software tools are described, and the incorporated statistical methods discussed and evaluated with respect to both published modern and fossil data, as well as the author’s own investigations.

  4. 8. Assessing environmental exposures. Air pollution in Scania, southern Sweden

    Författare :Ralf Rittner; Avdelningen för arbets- och miljömedicin; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; air pollution; dispersion modelling; health impact assessment; emission database; Particulate matter PM ; epidemiology;

    Sammanfattning : Background: The environment where we humans live provides the fundamental requirements we need to survive – food to eat, water to drink, and air to breathe. The quality of these elements has a major impact on human health, as they can contain substances that are detrimental to health. These we call environmental pollutants. LÄS MER

    Sammanfattning : This dissertation explores the early digitalization in Sweden. As host to the first summit on the environment in Stockholm 1972 (UNCHE), as leading procurer of computer equipment as well as initiator to the world's first national Data Act of 1973, Sweden pioneered domains that have since emerged as critical to our age: environmental challenges and digital technology.

  7. 10. Constraint-based conceptual design using principle solution elements

    Författare :Sören Wilhelms; Christian Weber; Linköpings universitet; []
    Nyckelord :Conceptual design; functional modelling; constraint-based design; design reuse; VDI 2222; product modelling; design support; TECHNOLOGY; TEKNIKVETENSKAP;

    Sammanfattning : The design of new products is an important engineering activity, and much of the competitiveness in high-salary countries depends on the ability to develop innovative products with acceptable time to market.During conceptual design, the principle solution for a product is conceived.
