  1. 1. Spectroscopy and RGB-Colorimetry for Quantification of Plant Pigment and Fruit Content in Fruit Drinks

    Kandidat-uppsats, Lunds universitet/Matematisk fysik; Lunds universitet/Fysiska institutionen

    Författare :Daniele Correia Rodman; [2018]
    Nyckelord :spectroscopy; RGB-colorimetry; Physics and Astronomy;

    Sammanfattning : Collimated Transmission Spectroscopy (CTS) is a technique that is commonly used to study the optical absorption of different media. In this work CTS was used to measure the absorbance of pure raspberry juice in order to investigate how well the fruit content may be determined in a commercially available raspberry fruit drink.

  2. 2. Temperature measurement in flames using TLAF, alkali emission and OH UV absorption

    Magister-uppsats, Lunds universitet/Fysiska institutionen; Lunds universitet/Förbränningsfysik

    Författare :Yuhe Zhang; [2018]
    Nyckelord :Physics and Astronomy;

    Sammanfattning : There is a continued need for reliable and convenient nonintrusive thermometric techniques for better understanding and effective control of combustion related processes. In this thesis, three spectroscopic thermometric methods were studied to evaluate the hot flue gas temperatures provided by a multi-jet burner. LÄS MER

  3. 3. Determination of fossil share in combustion of waste : Development of a novel method using NIR spectroscopy to predict the content of plastics in RDF-material

    Master-uppsats, Mälardalens högskola/Akademin för ekonomi, samhälle och teknik

    Författare :Christian Dahl; [2018]
    Nyckelord :NIR; Near infra-red; spectroscopy; chemometrics; waste material; fossil share;

    Sammanfattning : Incineration of waste materials has become a common way to handle a worldwide increase of produced waste materials. The problem with waste as fuel is that the material is not homogeneous and include a mixture of fossils and renewables. LÄS MER

  4. 4. Preparation of Materials for Deep Tissue Imaging with Slow Light

    Master-uppsats, Lunds universitet/Atomfysik; Lunds universitet/Fysiska institutionen

    Författare :Mengqiao di; [2018]
    Nyckelord :Ultrasound Optical Tomography; Deep Tissue Imaging; Monte Carlo Simulation; Spectral Hole Burning; Physics and Astronomy;

    Sammanfattning : Ultrasound Optical Tomography (UOT) is a proposed technique, which combines ultrasound imaging and optical imaging in a new way to detect, e.g. LÄS MER

  5. 5. Tunable diode laser absorptionspectroscopy of atomic potassium in a KOH-seeded flat flame

    Master-uppsats, Umeå universitet/Institutionen för fysik

    Författare :Mirjam Eriksson; [2018]
    Nyckelord :;

    Sammanfattning : Potassium (K) is the main ash-forming element released from biomass during thermochemical conversion. A better understanding of K chemistry and monitoring of K species is needed to optimize combustion systems. LÄS MER
