  1. 1. Studies in Glacier Mass Balance : Measurement and its errors

    Författare :Andrew Mercer; Peter Jansson; Gunhild Rosqvist; Ian Brown; Jonathan Carrivick; Stockholms universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Glaciology; Mass Balance; Measurement Errors; naturgeografi; Physical Geography;

    Sammanfattning : The study of the surface mass balance of valley glaciers has a long history but one that is dogged by uncertainty and errors, and uncertainty about those errors. These problems are acknowledged by the glaciological community and have been examined and formalised in several publications. LÄS MER

  4. 3. Developing Methods for Modelling Procedures in System Analysis and System Dynamics

    Författare :Hördur Haraldsson; Institutionen för kemiteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; System Dynamics; System Analysis; group model building; modelling procedures; innovation phases; modelling workflow; Natural science; Naturvetenskap; Technological sciences; Teknik;

    Sammanfattning : System Thinking is the mindset of defining and confining a problem and its symptoms as well as a method for communicating system understanding. System Analysis is taking that problem apart to understand its causalities and structural arrangement. LÄS MER

  5. 4. Bringing System Dynamics into Action Research

    Författare :Paul Holmström; Chalmers University of Technology; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; process consultation; Operations Research; simulation; action research; modelling; System Dynamics; healthcare;

    Sammanfattning : System Dynamics simulation is a computer-aided approach to policy analysis and design, often carried out by external experts in simulation. System Dynamics is particularly useful in complicated and complex situations, such as healthcare. However, research has shown that few models in healthcare are implemented. LÄS MER

  7. 5. Landscape Dynamics : Spatial analyses of villages and farms on Gotland AD 200-1700

    Författare :Gustaf Svedjemo; Frands Herschend; Helene Martinsson-Wallin; Jan Henrik Fallgren; Uppsala universitet; []
    Nyckelord :HUMANITIES; HUMANIORA; HUMANIORA; HUMANITIES; Gotland; Archaeology; History; Historical maps; Roman Iron Age; Migration Period; Middle Ages; Village; Village formation; Farm; Settlement archaeology; Spatial analyses; GIS; Prediction modelling.; Gotland; Arkeologi; Historia; Historiska kartor; Romersk järnålder; Folkvandringstid; By; Bybildning; Gård; Bebyggelsearkeologi; rumsliga analyser; GIS; Geografiska informationssystem; prediktionsmodellering;

    Sammanfattning : This dissertation deals with the long-term dynamics and fluctuations of settlements on Gotland for the period from AD 200 up until early modern times. The settlement structure on Gotland is most often described as very stable and consisting of solitary farms, established in the Iron Age. LÄS MER
