    Författare :Nancy Joy Lim; Stefan Seipel; S. Anders Brandt; Eva A. U. Sahlin; Matthew Wilson; Högskolan i Gävle; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; cartography; flood; hydraulic modelling; GIS; map; uncertainty; visualisation; GIS; hydraulisk modellering; karta; kartografi; osäkerhet; visualisering; översvämning; Hållbar stadsutveckling; Sustainable Urban Development;

    Sammanfattning : Flood maps showing extents of predicted flooding for a given extreme event have wide usage in all types of spatial planning tasks, as well as serving as information material for the public. However, the production processes that these maps undergo (including the different data, methods, models and decisions from the persons generating them), which include both Geographic Information Systems (GIS) and hydraulic modelling, affect the map’s content, and will be reflected in the final map.

  3. 2. A Mode Switching Modelling Philosophy

    Författare :Jan-Erik Strömberg; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : The thesis presents a modelling methodology for the systematic derivation of mathematical behaviour mod els of engineering systems , i. e. systems constructed by engineers. The first part presents the theoretical and philosophical foundation underlying a dass of methods generally referred to as physical modelling. LÄS MER

  4. 3. Coordinated Voltage Control in Electric Power Systems

    Författare :Mats Larsson; Lunds universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Electronics and Electrical technology; trees.; search methods; control; predictive; voltage control; power system dynamic stability; Modelica; ObjectStab; multi-machine power system; voltage stability; object oriented methods; modelling; simulation; describing function analysis; tap changer; limit cycle; Elektronik och elektroteknik; Electrical engineering; Elektroteknik;

    Sammanfattning : This thesis deals with various aspects of coordinated voltage control in electric power systems. It consists of an introduction and six papers. The introduction contains a summary of the thesis and tutorials on voltage control and the search methods that have been applied. LÄS MER

  5. 4. 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.

  7. 5. Mathematical Modelling of Insulin Signalling : Effects on Glucose Metabolism in Skeletal Muscle

    Författare :Peter Sögård; Högskolan i Skövde; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Naturvetenskap; Natural sciences;

    Sammanfattning : The use of models to understand complex phenomena is indispensable to the scientific community. The advantage of a model is that it simplifies the phenomena under study. However, a model should be only as complex as required, no more, no less. LÄS MER
