  1. 6. Low Frequency Impact Sound in Timber Buildings : Simulations and Measurements

    Författare :Jörgen Olsson; Andreas Linderholt; Leif Kari; Linnéuniversitetet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Low-frequency; impact sound; light weight floor; timber joist floor; tapping machine; multi-storey timber building; frequency response functions.; Stegljud; Byggteknik; Civil engineering;

    Sammanfattning : An increased share of construction with timber is one possible way of achieving more sustainable and energy-efficient life cycles of buildings. The main reason is that wood is a renewable material and buildings require a large amount of resources. LÄS MER

  3. 7. Construction of force measuring optical tweezers instrumentation and investigations of biophysical properties of bacterial adhesion organelles

    Författare :Magnus Andersson; Ove Axner; Lene Broeng Oddershede; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; optical tweezers; biological physics; unfolding; Escherichia coli; force measurements; energy landscape; dynamic force spectroscopy; manipulation; polymers; pili; Physics; Fysik;

    Sammanfattning : Optical tweezers are a technique in which microscopic-sized particles, including living cells and bacteria, can be non-intrusively trapped with high accuracy solely using focused light. The technique has therefore become a powerful tool in the field of biophysics. LÄS MER

  5. 9. Investigating nano-scale viscous and elastic forces withintermodulation : Studies in multifrequency atomic force microscopy

    Författare :Per-Anders Thorén; David B. Haviland; Greg Haugstad; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Atomic Force Microscopy; Nonlinear dynamics; Soft materials; High- speed friction measurements; Modeling and numerical simulations; Fysik; Physics;

    Sammanfattning : Investigating visco-elastic forces at the nanometer-scale is important to thecharacterization of soft materials. A quantitative force measurement can be ob-tained using an atomic force microscope (AFM) with a calibrated force transducer(the AFM cantilever). LÄS MER

  7. 10. Measurement of shear force, temperature profiles and fibre development in mill-scale TMP refiners

    Författare :Hans-Olof Backlund; FSCN - Fibre Science and Communication Network; []
    Nyckelord :Shear force; Tangential force; Temperature profile; Thermomechanical pulping;

    Sammanfattning : Two different force sensors have been developed for tangential forcemeasurements in commercial TMP refiners, one is based on the use of piezoelectricsensors and the other on strain gauges. The measurements are used to learn moreabout the refining mechanism in both single-disc (SD) refiners and conical disc(CD) refiners. LÄS MER
