  1. 16. Brain activity during flow : A systematic review

    Kandidat-uppsats, Högskolan i Skövde/Institutionen för biovetenskap

    Författare :Isak Andersson; [2022]
    Nyckelord :Flow state; neural signatures; functional magnetic resonance imaging; functional near-infrared spectroscopy; electroencephalogram;

    Sammanfattning : The flow state is a subjective experience that most people can relate to. It represents an optimal balance between skills and difficulty and is the state that people often refer to when performing their best, with phrases like: “I was in the zone” or “I was in the bubble”.

    Sammanfattning : The use of plastic materials has changed the packaging industry, the construction industry, the automotive industry, and many others drastically. Plastics are also abundant in our everyday life. However, its downsides in the society are undeniable and are starting to get attention from law makers, the general public and industries alike.

    Sammanfattning : The global energy demand supplies mainly from fossil fuels, which is neither sustainable nor environmentally friendly and aims to global warming. Therefore, both more investments in renewable energy sources such as bioenergy are required, as well as new technologies such as carbon capture and storage (CCS) to handle the emissions from existing combined heat and power (CHP) plants.

  5. 19. Towards a high resolution view of infrared line formation

    Master-uppsats, Lunds universitet/Astronomi - Genomgår omorganisation

    Författare :Martin Schmidt Montelius; [2021]
    Nyckelord :Spectroscopy; Near infrared; K giants; Galactic archeaology; Galactic chemical evolution; Abundances; Milky Way; Physics and Astronomy;

    Sammanfattning : Observing in the infrared has many benefits, such as seeing through the interstellar dust in the galaxy, easier use of adaptive optics, and better flux ratios for direct observations of exoplanets. Before the infrared spectral range can be utilised for highly accurate stellar spectroscopy there is a need for a better understanding of both stellar modelling and the atomic physics that go into forming spectral lines.

  7. 20. Development of a Near Infrared Spectroscopy Model for Prediction of Fibre Compounds in Alfalfa

    Master-uppsats, Lunds universitet/Teknisk mikrobiologi

    Författare :Christina Andersen; [2020]
    Nyckelord :alfalfa; lucerne; medicago sativa; green protein powder; NIR; near infrared spectroscopy; model development; matlab; PLS; partial least squares; PCA; principal component analysis; SNV; standard normal variate; fibre prediction; TDF; total dietary fibre; applied microbiology; teknisk mikrobiologi; Technology and Engineering;

    Sammanfattning : Background: This project investigates if it is possible to develop a calibration model from near infrared (NIR) spectroscopic measurements, for determination of the amount and type of fibre fractions within protein powder produced from the legume alfalfa, without performing wet experiments. Alfalfa is also known as Medicago sativa and lucerne, but is in this project further referred to as alfalfa. LÄS MER
