  1. 1. Footbridge Dynamics : Human-Structure Interaction

    Författare :Emma Zäll; Raid Karoumi; Mahir Ülker-Kaustell; Andreas Andersson; Peter Van den Broeck; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Dynamics; vibration; footbridge; pedestrian bridge; human-structure interaction; runner; running loads; simplified models; Dynamik; vibration; gångbro; människa-bro-interaktion; löpare; löparlaster; förenklade modeller; Civil and Architectural Engineering; Byggvetenskap;

    Sammanfattning : For aesthetic reasons and due to an increased demand for cost-effective and environmentally friendly civil engineering structures, there is a trend in designing light and slender structures. Consequently, many modern footbridges are susceptible to excessive vibrations caused by human-induced loads. LÄS MER

  3. 2. Employment Dynamics

    Författare :Karolina Stadin; Nils Gottfries; Bertil Holmlund; Eran Yashiv; Uppsala universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Employment dynamics; Labor demand; Matching; Vacancies; Unemployment; Business cycle; Firm behavior; Capital stock; Inventories;

    Sammanfattning : The main focus of this thesis is the employment decisions of firms. The thesis consists of three self-contained but closely related essays, all enlightening employment dynamics in different ways. The thesis is mainly empirical but there are also some theoretical developments when existing theory is insufficient to explain the empirical findings. LÄS MER

    Författare :Daniel Halvarsson; Kristina Nyström; Joachim Wagner; KTH; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Firm size distribution; High-growth firms; Gazelles Firm growth- rate distribution;

    Sammanfattning : This thesis is about firm dynamics, and relates to the size and growth-rate distribution of firms. As such, it consists of an introductory and four separate chapters. LÄS MER

  7. 5. Lattice dynamics : From fundamental research to practical applications

    Författare :Johan Tidholm; Igor A. Abrikosov; Olle Hellman; Ferenc Tasnadi; Gerd Steinle-Neumann; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : The reason to perform calculations in material science usually falls into one of two categories: to predict or explain the origin of material properties. This thesis covers first-principle calculations for solids at extreme conditions, from both of the two mentioned categories. LÄS MER
