  1. 6. Identification of Environmental Plastic Samples from a Caribbean Beach Survey by Near-Infrared Spectroscopy with the MicroNIR and Chemometric Analysis

    University essay from Örebro universitet/Institutionen för naturvetenskap och teknik

    Author : David Vigren; [2015]
    Keywords : MicroNIR; Near-infrared spectroscopy; Chemometrics; Plastic polymer identification; Environmental plastic beach survey;

    Abstract : MicroNIR is a portable near-infrared diffuse reflection spectroscope. Its suitability for identifying environmental plastic polymers was evaluated through a series of performance tests. The plastic samples were collected during a beach survey in the Caribbean. First a reference database was built by analysing a series of reference plastic polymers. READ MORE

  3. 7. Broadband Photon Time-of-Flight Spectroscopy on Pharmaceutical Tablets and Dairy Products

    University essay from Lunds universitet/Fysiska institutionen; Lunds universitet/Atomfysik

    Author : Sören Johansson; [2015]
    Keywords : Compositional Analysis; Dairy; Tablets; Pharmaceutics; Scattering; Absorption; Spectroscopy; Photonics; Optics; Chemometrics; Partial Least Squares; PLS; Physics and Astronomy;

    Abstract : In this thesis, Photon Time-of-Flight Spectroscopy (PTOFS) is presented as a method to measure absorption and scattering spectra of turbid media samples in the near infra red wavelength range. In particular, absorption and scattering spectra measured on pharmaceutical tablets and dairy products are used to analyse the composition of the samples. READ MORE

  4. 8. A method for predicting baking performance through evaluation of short crust dough

    University essay from Lunds universitet/Livsmedelsteknik och nutrition (master)

    Author : Rana Cheaib; [2015]
    Keywords : baking performance; food technology; livsmedelsteknologi; chemometrics; statistical tools; fat; egg; Technology and Engineering; Agriculture and Food Sciences;

    Abstract : The three major components of short-crust cookie dough are flour, sugar, and fat. Since high fat contents have been shown to have a major effect on the development of the gluten network, studying how these ingredients could affect the texture of the dough and the baked product became interesting.

  5. 9. Forecasting the Business Cycle using Partial Least Squares

    University essay from KTH/Matematisk statistik

    Author : Fredrik Lannsjö; [2014]
    Keywords : Quantitative Forecast; Partial Least Squares; Variable Selection; High-dimensional Regression; Big Data; Business Cycle; Leading Indicators;

    Abstract : Partial Least Squares is both a regression method and a tool for variable selection, that is especially appropriate for models based on numerous (possibly correlated) variables. While being a well established modeling tool in chemometrics, this thesis adapts PLS to financial data to predict the movements of the business cycle represented by the OECD Composite Leading Indicators.

  6. 10. Untargeted metabolomics to assess effects of rye diet enriched with plant protein and fermentable fiber on appetite

    University essay from SLU/Dept. of Food Science

    Author : Magnus Lindelöf; [2014]
    Keywords : rye; dietary fiber; protein; satiety; humans; plasma; metabolomics; untargeted; NMR; speaq; chemometrics;

    Abstract : Rye products are known to more effective decrease different aspects of subjective appetite compared to low fiber wheat bread. Nutritional composition and structural properties, such as dietary fiber components and grain integrity are thought to play roles in the satiating mechanism behind this appetite reduction. READ MORE
