  1. 31. Establishing a predictive model for total fat content in Lipomyces starkeyi CBS 1807 by FT-NIR analysis

    University essay from SLU/Department of Molecular Sciences

    Author : Irina Ehnström; [2018]
    Keywords : Oleaginous microorganisms; SCO; biofuels; FT-NIR; lipid extraction; prediction; validation;

    Abstract : This study investigates the potential of using near- infrared spectroscopy (FT-NIR) to establish a predictive model for total fat content in the oleaginous yeast Lipomyces strakeyi CBS 1807. FT-NIR- based quantification allows for rapid lipid determination compared to traditional extraction methods. READ MORE

  3. 32. Modeling the cavity dispersion in cavity-enhanced optical frequency comb Fourier transform spectroscopy

    University essay from Umeå universitet/Institutionen för fysik

    Author : Adrian Hjältén; [2018]
    Keywords : ;

    Abstract : Cavity enhanced optical frequency comb spectroscopy is a technique that allows for quick and sensitive measurements of molecular absorption spectra. Locking the comb lines of an optical frequency comb to the cavity modes of an enhancement cavity and then extracting the spectral information with a Fourier transform spectrometer grants easy access to wide segments of absorption spectra.

  4. 33. 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

    University essay from Mälardalens högskola/Akademin för ekonomi, samhälle och teknik

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

    Abstract : 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. READ MORE

  5. 34. Detection of glass in RDF using NIR spectroscopy

    University essay from Mälardalens högskola/Akademin för ekonomi, samhälle och teknik

    Author : Philip Hedlund; [2018]
    Keywords : NIR; spectroscopy; RDF; glass; CFB; boiler; performance; losses; NIR; spektroskopi; RDF; glas; CFB; panna; prestanda; förluster;

    Abstract : Purpose of this study was to investigate the possibilities of using Near-infrared (NIR) spectroscopy to detect glass in refuse derived fuel (RDF) as well as what on-line data of glass content could be used for in terms of boiler operation and performance determination. Sample configurations were done with dried RDF (to prevent mass loss due to moisture and spectroscopic disturbance) and increasing concentrations of colored soda-lime glass, total of 100 samples.

  6. 35. Simulation of Solar System Objects for the NISP instrument of the ESA Euclid Mission

    University essay from Luleå tekniska universitet/Institutionen för system- och rymdteknik

    Author : Vanshika KANSAL; [2018]
    Keywords : Solar System Objects; NISP; Spectroscopy; photometry; Euclid;

    Abstract : Euclid is a medium class mission designed to study the geometry of dark universe. It will work in the visible and near infrared imaging & spectroscopy for a lifetime of 6 years down to the magnitude of mAB = 24. READ MORE
