  4. 2. Human response to wind turbine noise : perception, annoyance and moderating factors

    Author : Eja Pedersen; Sten Ljunggren; Högskolan i Halmstad; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Noise; Environmental exposure; Wind; Audio-visual interaction; Low-level noise exposure; NATURAL SCIENCES; NATURVETENSKAP; wind turbines; noise annoyance; sound perception; audio-visual interaction; low-level noise exposure;

    Abstract : Aims: The aims of this thesis were to describe and gain an understanding of how people who live in the vicinity of wind turbines are affected by wind turbine noise, and how individual, situational and visual factors, as well as sound properties, moderate the response.Methods: A cross-sectional study was carried out in a flat, mainly rural area in Sweden, with the objective to estimate the prevalence of noise annoyance and to examine the dose-response relationship between A-weighted sound pressure levels (SPLs) and perception of and annoyance with wind turbine noise.

  5. 3. Influence of Nuclear Structure on Decay Properties of Heavy Nuclei

    Author : Daniel Ward; Matematisk fysik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; alpha decay; hindrance factors; Skyrme-Hartree-Fock-Bogoliubov model; superheavy nuclei; fission yields; Brownian-shape motion; nuclear structure; nuclear level density; alpha decay; hindrance factors; Skyrme-Hartree-Fock-Bogoliubov model; superheavy nuclei; fission yields; Brownian-shape motion; nuclear structure; nuclear level density; Fysicumarkivet A:2017:Ward;

    Abstract : This dissertation deals with the effects of nuclear structure on the α-decay properties, and on the fission-yielddistributions from the decay of heavy nuclei. The nuclear-structure and decay properties of superheavynuclei is one of the central topics for investigation. READ MORE

  6. 4. FEM Modelling of Micro-galvanic Corrosion in Al Alloys Induced by Intermetallic Particles : Exploration of Chemical and Geometrical Effects

    Author : Litao Yin; Jinshan Pan; Christopher Leygraf; Ying Jin; Herman Terryn; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Finite Element Method FEM ; Modelling; Micro-galvanic corrosion; Al alloy; corrosion product deposition; chemical factors; steric hindrance effect; Kemi; Chemistry;

    Abstract : Localized corrosion, such as pitting, crevice corrosion or galvanic corrosion, is a long-standing phenomenon that can greatly limit the life of metallic materials. For decades experimental methods have been used to try to understand the underlying physical, chemical and electrochemical processes that control localized corrosion in order to find effective protection methods against its propagation.

  7. 5. Human factors in mechanized cut-to-length forest operations

    Author : Carola Häggström; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Abstract : Although forest operations research has a more than 50-year-long tradition in the field of human factors, there is a current decline in resources put on continuous and systematic human factors research. Therefore, the overall aim of this thesis was to contribute new knowledge on working conditions in mechanized cut-to-length logging operations and their relationship to system performance. READ MORE
