  1. 1. Reduced Order Modeling and Substructuring : Applications in Nonlinear Structural Dynamics

    Författare :Linus Andersson; Byggnadsmekanik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Reduced order modeling; Substructuring; Nonlinear dynamics; Geometrically nonlinear; Modal derivatives; Blast loading; Soft-body impact; Glass structures;

    Sammanfattning : A structural design process typically involves various load cases for which a sufficient load-bearing capacity must be demonstrated. In addition to static load cases, a verification of dynamic loads, such as blast and impact loading, may be required. LÄS MER

  3. 2. Testing the unit root hypothesis in nonlinear time series and panel models

    Författare :Rickard Sandberg; Handelshögskolan i Stockholm; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : The thesis contains the four chapters: Testing parameter constancy in unit root autoregressive models against continuous change; Dickey-Fuller type of tests against nonlinear dynamic models; Inference for unit roots in a panel smooth transition autoregressive model where the time dimension is fixed; Testing unit roots in nonlinear dynamic heterogeneous panels. In Chapter 1 we derive tests for parameter constancy when the data generating process is non-stationary against the hypothesis that the parameters of the model change smoothly over time. LÄS MER

    Sammanfattning : Paper 1: Country Size and the Rule of Law: Resuscitating Montesquieu In this paper, we demonstrate that there is a robust negative relationship between the size of country territory and a measure of the rule of law for a large cross-section of countries. We outline a theoretical framework featuring two main reasons for this regularity; firstly that institutional quality often has the character of a local public good that is imperfectly spread across space from the core of the country to the hinterland, and secondly that a large territory usually is accompanied by valuable rents and a lack of openness that both tend to distort property rights institutions.
