  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. New ways of learning : Participatory action research and Kenyan runners’ appropriation of smartphones to improve their daily lives and participation in m-learning

    Författare :Per-Olof Hansson; Per Andersson; Elin Wihlborg; Rodderick Fox; Linköpings universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Participatory action research; m-learning; sociocultural perspective; Deltagande aktionsforskning; mobilt lärande; sociokulturellt perspektiv;

    Sammanfattning : In Kenya, mobile technology is widely used, with more and more people gaining access to the Internet. Mobile technology has the potential to support learning and improve lives, particular those of impoverished people. In this study, 30 Kenyan runners from poor backgrounds and with limited formal education participated. LÄS MER

  4. 3. On the Challenges for Time-of-Flight Electron Spectroscopy at Storage Rings

    Författare :Christian Stråhlman; Lunds universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; time-of-flight; photoelectron spectroscopy; MAX IV; storage ring; detector gating; chopper; coincidence spectroscopy;

    Sammanfattning : Time-of-flight (TOF) techniques for energy analysis have been common in electron spectroscopy for many decades. TOF-based electron spectrometers benefit from higher transmission and information rate compared to their main competitor: the hemispherical analyser; the drawback being their lower energy resolution.
