  1. 1. Maktlösa makthavare : En studie om kommunalt chefskap

    Författare :Örjan Högberg; Peter Gustavsson; Leif Jonsson; Rolf Solli; Linköpings universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; power; influence; critical realism; social structures; causality; makt; påverkan; kritisk realism; sociala strukturer; kausalitet; Business and economics; Ekonomi;

    Sammanfattning : Enligt den svenska förvaltningstraditionen, vilken bygger på den Weberianska byråkratimodellen, ska politiker fatta beslut och tjänstemännen verkställa dem. Men, relationen mellan politiker och tjänstemän i den kommunala vardagen förefaller inte vara så enkel. LÄS MER

    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Parameterisation; runoff generation; routing; WASMOD-M; hydrography; data uncertainty; topographic index; scale; river network; response function; HydroSHEDS; HYDRO1k; Dongjiang basin; Parametrisering; avrinningsbildning; flödessvarstid; WASMOD-M; hydrografi; topografiskt index; dataosäkerhet; skala; flödesnät; svarstidssfunktion; HYDRO1k; HydroSHEDS; Dongjiang; Hydrology; Hydrologi; Hydrology; Hydrologi;

    Sammanfattning : Water has always had a controlling influence on the earth’s evolution. Understanding and modelling the large-scale hydrological cycle is important for climate prediction and water-resources studies. LÄS MER

  4. 3. Macroeconomic Studies on Fiscal Policy and Real Exchange Rates

    Författare :Göran Hjelm; Nationalekonomiska institutionen; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; econometrics; economic theory; Total factor productivity; Economics; Real exchange rates; Structural VAR models; Partisan models; Fiscal policy; Fiscal contractions; economic systems; economic policy; Nationalekonomi; ekonometri; ekonomisk teori; ekonomiska system; ekonomisk politik;

    Sammanfattning : This thesis contains four empirical macroeconomic studies and the papers may briefly be summarized as follows. In the first paper, we use both descriptive statistics and regression analysis to investigate whether movements in real exchange rates and money supply before and during fiscal contractions matter for the macroeconomic outcome.

  5. 4. Analyses of shotcrete stress states due to varying lining thickness and irregular rock surfaces

    Författare :Andreas Sjölander; Anders Ansell; Richard Malm; Fredrik Johansson; Jan Alemo; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Shotcrete; cracking; shrinkage; block load; varying thickness; numerical simulations; fibre reinforcement; Byggvetenskap; Civil and Architectural Engineering;

    Sammanfattning : Shotcrete is sprayed concrete applied pneumatically under high pressure and was invented in the beginning of the 1900's. This new technique decreased the construction time and since steel fibres were introduced in the shotcrete during the 1970's, shotcrete has been the primary support method for tunnels. LÄS MER

  7. 5. Modelling Fiber Network Materials:Micromechanics, Constitutive Behaviour and AI

    Författare :Mossab Alzweighi; Artem Kulachenko; Rami Mansour; Sören Östlund; Manfred Ulz; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Solid Mechanics; Hållfasthetslära;

    Sammanfattning : This thesis focuses on understanding the mechanical behavior of fiber-based materials by utilizing various modeling approaches. Particular emphasis is placed on their structural variability, anisotropic properties, and damage behavior. LÄS MER
