  1. 6. Structural-acoustic vibrations in wooden assemblies : Experimental modal analysis and finite element modelling

    Författare :Åsa Bolmsvik; Torbjörn Ekevik; Andreas Linderholt; Anders Brandt; Anders Ågren; Linnéuniversitetet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; wooden framed structure; light weight buildings; multi-storey; flanking transmission; junction; vibration distribution; impact noise; damping; elastomers; finite element analysis; experimental modal analysis; FRF; trästomme; träkonstruktion; träbyggnad; flervåningshus; EMA; FEM; flanktransmission; koppling; knutpunkt; vibrationsspridning; stomljud; stegljud; dämpning; elastomerer; finit elementmetod; experimentell modalanalys; accelerationsmätning; frekvensresponsfunktion; modalanalys;

    Sammanfattning : This doctoral thesis concerns flanking transmission in light weight, wooden multi-storey buildings within the low frequency, primarily 20-120 Hz. The overall aim is to investigate how the finite element method can contribute in the design phase to evaluate different junctions regarding flanking transmission. LÄS MER

  3. 7. Drum sound from floor coverings - objective and subjective assessment

    Författare :Ann-Charlotte Johansson; Teknisk akustik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; vakuumteknik; vibrationer; akustik; hydraulik; Maskinteknik; vacuum technology; vibration and acoustic engineering; hydraulics; acoustic standard; Mechanical engineering; tapping machine; veneer flooring; parquet flooring; binaural recording; foot impact; loudness; sound quality; listening test; paired comparisons; walking sound; drum sound; building acoustics; psychoacoustics; laminate flooring;

    Sammanfattning : Drum sound is the sound produced when an object, such as a foot, hits the flooring in the room in which the receiving ear is located. Drum sound has attracted interest in recent years, particularly due to an increased use of thin floating floor constructions, such as veneer or laminate flooring, which can produce loud and sharp walking sound.

  4. 8. Determination and control of some pollutants in indoor environments

    Författare :Pawel Markowicz; Avdelningen för medicinsk mikrobiologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; indoor air quality; indoor pollutants; dampness; purification; tobacco smoke;

    Sammanfattning : Unsatisfactory indoor air quality (IAQ) may result from polluting emissions that are spread from building materials such as volatile organic compounds (VOCs) and/or microbial components or from various kinds of human activity such as smoking. Different methods are available to limit the exposure to unwanted pollutants and improve human wellbeing and health. LÄS MER

  5. 9. Living and Dying with Primary Sjögren's Syndrome Studies on Aetiology, Treatment, Lymphoma, Survival and Predictors

    Författare :Elke Theander; Internmedicin - epidemiologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Skeleton; transplantation; muskelsystem; Skelett; rheumatology locomotion; long-term outcome; Sjögren s Syndrome; Helicobacter pylori infection; prospective cohort studies; SMR; SIR for lymphoproliferative disease; fatigue; health-related quality of life; complement function; oncology; Cytologi; Immunology; cancer; serologi; Immunologi; serology; cancerology; onkologi; reumatologi; muscle system; CD4 T-lymphocytopenia; Cytology;

    Sammanfattning : This work was aimed at improving our understanding of the course of primary Sjögren's syndrome (SS). The Malmö SS patient register and the 2002 American-European Consensus Criteria formed the basis of all studies. Helicobacter pylori (H. LÄS MER

  7. 10. Redistribution of moisture and ions in cement based materials

    Författare :Magnus Åhs; Avdelningen för Byggnadsmaterial; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Moisture redistribution; ion redistribution; cement based materials; hysteresis; sorption isotherm; scanning;

    Sammanfattning : There were two principal objectives for this thesis. The first was to develop a methodology and evaluation model of moisture redistribution in order to make the future relative humidity in a screeded concrete slab predictable. The second objective was to develop a method to determine the critical humidity for ion transport in concrete. LÄS MER
