  1. 6. Road surface classification using near infrared spectroscopy

    Författare :Johan Casselgren; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Experimentell mekanik; Experimental Mechanics;

    Sammanfattning : Statistics shows that most traffic accidents with fatal outcome can be related to slippery road conditions. The most hazardous road conditions are the ones that are hard for the driver to detect and that appears sudden on the road. LÄS MER

  3. 7. Laser Spectroscopy in Scattering Media for Biological and Medical Applications

    Författare :Linda Persson; Atomfysik; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Instrumentation technology; Mät- och instrumenteringsteknik; Atom- och molekylärfysik; Atomic and molecular physics; Fysik; Physics; Monte Carlo simulations; Biomedical Optics; Scattering media; Gas measurements; Near infrared spectroscopy; Diode laser spectroscopy; Absorption spectroscopy;

    Sammanfattning : Tunable diode laser absorption spectroscopy can be utilised for gas detection in biological and medical applications. The common approach is to analyse transmitted light according to the Beer-Lambertian law. LÄS MER

  4. 8. Time-Resolved Spectroscopy for Pharmaceutical Applications

    Författare :Christoffer Abrahamsson; Atomfysik; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Elektromagnetism; optik; Near-infrared spectroscopy; Time-resolved spectroscopy; Pharmaceutical analysis; Multivariate data analysis; Electromagnetism; Light transport in turbid media; Photon migration; akustik; acoustics; optics;

    Sammanfattning : The work presented in this thesis aims at improving spectroscopic techniques for analysis of pharmaceutical solids. This improvement is achieved by the combining and development of instrumentations and data evaluation tools from two research fields: the fields of near infrared spectroscopy and biomedical optics.

  5. 9. Near infrared spectroscopy for assessing oxygenation and hemodynamics in the upper extremities of healthy subjects and patients with work-related muscle pain

    Författare :Guilherme H. Elcadi; Albert G. Crenshaw; Mikael Forsman; Martin Fahlström; Svend Erik Mathiassen; Karen Sogaard; Högskolan i Gävle; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Near infrared spectroscopy; muscle oxygenation; hemodynamics; electromyography; extensor carpi radialis; trapezius; fysiologi;

    Sammanfattning : The prevalence of work-related muscle pain (WRMP) is large in the general population in the industrialized world. Despite significant advances over recent years in some research areas, the mechanisms of why WRMP occurs and the pathophysiological mechanisms behind the disorders are still unclear. LÄS MER

  7. 10. Improved farm soil mapping using near infrared reflection spectroscopy

    Författare :Johanna Wetterlind; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Sammanfattning : Information on soil texture, soil organic matter content (SOM), nutrient status and pH is fundamental for efficient crop production and for minimising negative effects on the environment. Farmers obtain this information, on which decisions on fertiliser and lime requirements are based, through farm soil mapping. LÄS MER
