  2. 21. Analysis of Power Performance and Mooring Fatigue Damage for Wave Energy Parks

    Author : Xinyuan Shao; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; mooring fatigue; power output; WEC; SESAM; potential theory; wave energy park; CFD; STAR-CCM ;

    Abstract : Wave energy has been recognized as a promising alternative to traditional energy sources due to its cleanliness and sustainability. To harness this energy, wave energy converters (WECs) are utilized. READ MORE

  4. 22. The influence of modelling parameters on the simulation of car tyre rolling losses and rolling noise

    Author : Carsten Hoever; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; rolling resistance; modelling parameters; parameter study; radiation; tyre road noise; tyres; tyre road interaction; waveguide finite element;

    Abstract : Due to legislative changes within the EU there is an increased demand for improvement in car tyre rolling resistance and noise generation. Yet, apart from empirical data based on measurements, there is little information concerning the relationship between rolling resistance and rolling noise generation. READ MORE

  5. 23. By foot at ease : environmental affordances for wellbeing in walking

    Author : Thomas Höjemo; Beatriz Fedrizzi; Anna-Johanna Klasander; Universidade Federal do Rio Grande do Sul; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; HUMANIORA; HUMANITIES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES;

    Abstract : Walking has been shown to provide benefits for our health and also for the environment. Research has also shown that if the built environment is adapted for pedestrians, people walk more. However, there is a lack of qualitative research in architecture and urban design on walking at the micro (streetscape) scale. READ MORE

    Abstract : Transportation is the main source of environmental noise in Europe, with an estimated 125 million people affected by excessive noise levels from road traffic, causing a burden of noise related diseases and having a substantial economic impact on society. In order to reduce exposure to high levels of traffic noise, two approaches are the topic of extensive research: preventing sound from propagating from roads and railways using for example noise barriers, and reducing the sources of noise themselves.
