  1. 1. Dynamic Interactions : National Political Parties, Voters and European Integration

    Författare :Johan Hellström; Svante Ersson; Mikko Mattila; Umeå universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Euroscepticism; European integration; dynamic representation; panel data; party positions; political parties; public opinion; voters; Political science; Statsvetenskap; statskunskap; political science;

    Sammanfattning : This thesis consists of an introduction and four self-contained papers, designated I-IV, which extend previous research on national political parties and voters in Western Europe. More specifically, the issues addressed are parties’ positions and voters’ opinions on European integration and their dynamic interactions, i.e. LÄS MER

  3. 2. Dynamic Rating with Applications to Renewable Energy

    Författare :Kateryna Morozovska; Patrik Hilber; Tor Laneryd; Hans Ezz Edin; Adamantios Marinakis; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; dynamic rating; dynamic line rating; dynamic transformer rating; power transformers; power system optimization; wind farm planning; Electrical Engineering; Elektro- och systemteknik;

    Sammanfattning : Dynamic rating (DR) of power components is a method for assessing real-time capacity of large scale power transmission and distribution devices (commonly: transmission lines, power transformers, underground cables) and using this knowledge for adjusting loading limits of these components. Dynamic rating of power lines or dynamic line rating (DLR) is a pioneering technology in the area of dynamic rating.

  4. 3. Dynamic Knowledge Integration : A field study of an Information Systems Development Project

    Författare :Linnéa Wahlstedt; Lars Lindkvist; Tim Brady; Linköpings universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Knowledge integration process; collective heuristic; development projects; problem-solving; knowledge diversity; field study; Kunskapsintegrationsprocess; kollektiv heuristik; utvecklingsprojekt; problemlösning; kunskapsbaserade olikheter; fältstudie;

    Sammanfattning : Current research on knowledge integration offers valuable structural analyses of factors that influence knowledge integration, performance outcomes, and knowledge integration mechanisms. Less attention has been paid to how knowledge integration is carried out over time in cross-functional development projects. LÄS MER

  5. 4. Dynamic train/track interaction : hanging sleepers, track stiffness variations and track settlement

    Författare :Andreas Lundqvist; Linköpings universitet; []
    Nyckelord :TECHNOLOGY; TEKNIKVETENSKAP;

    Sammanfattning : Trains have been operating on ballasted tracks for over 150 years. During this time demands from the railway organisations and from the industry to increase axle loads and train speeds on the existing railway lines have increased. The reasons for this are both economial and environmental. LÄS MER

  7. 5. Variational Inference of Dynamic Factor Models

    Författare :Erik Spånberg; Pär Stockhammar; Gebrenegus Ghilagaber; Sune Karlsson; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; dynamic factor models; variational inference; missing data; nowcasting; expectation maximization; statistik; Statistics;

    Sammanfattning : When we make difficult and crucial decisions, forecasts are powerful and important tools. For that purpose, statistical models can be our most effective aid. Ideally, these models can incorporate large sets of multifaceted data. LÄS MER
