  1. 21. Lignin Biorefining: Swelling and activation of fibers for lignin extraction

    University essay from KTH/Fiber- och polymerteknologi

    Author : Ali Al Husseinat; [2023]
    Keywords : Biorefining; Carboxymethylation; Extraction; Lignin; Swelling; Bioraffinering; Extraktion; Karboxymetylering; Lignin; Svällning;

    Abstract : I världens omvandling mot en bioekonomi kommer lignocellulosa material spela en stor roll i ersättningen av fossila resurser. Lignin är den mest tillgängliga källan av förnybara och naturligt förekommande aromatiska ämne och den utgör 15–30% av ved. READ MORE

  2. 22. Deep Learning Based Out-of-focus Detection on Surveillance Footage

    University essay from Lunds universitet/Matematik LTH

    Author : Hanna Bengtsson; Teodora Kerac; [2023]
    Keywords : Deep Learning; CNN; Out-of-focus detection; Mathematics and Statistics;

    Abstract : Loss of focus in surveillance cameras can occur due to factors such as environmental aspects, sabotage or system errors. The focus loss leads to degraded footage that is of no use for either post-investigation or automatic video analysis. READ MORE

  3. 23. EEG-Based Speech Decoding Using a Machine Learning Pipeline

    University essay from KTH/Skolan för kemi, bioteknologi och hälsa (CBH)

    Author : Julia Önerud; [2023]
    Keywords : EEG; EEG-Decoding; Speech-like; Neuro; Neurotech; Machine-learning; SVM; Feature Extraction; Feature Selection; Mentalab; Inner Speech; OVR; Baseline-Correction; State-of-the-art; State-of-the-art Accuracy; Directions; Emotions;

    Abstract : his project aims to find a method that will help fill the information gaps in electroencephalography (EEG) brain-computer interfaces (BCI) research, by creating a pipeline method that allows for quicker research iterations than current state-of-the-art methods. The pipeline method is a multi-step processstarting from the recording EEG data from a subject performing a thought paradigm action, continuing with processing and decoding of the data, and ending with visualization and analysis the decoded results.

  4. 24. Microplastics in food webs- occurrence in Lake Vänern brown trout (Salmo trutta) and its main prey

    University essay from Karlstads universitet/Fakulteten för hälsa, natur- och teknikvetenskap (from 2013)

    Author : Hanna Nordström; [2023]
    Keywords : microplastic; freshwater; fish; brown trout; mikroplast; sötvatten; fisk; öring;

    Abstract : Over the past decade, research on microplastic pollution has gained significant attention. Research regarding microplastic occurrence in freshwater fish, however is still scarce. While possible pathways have been investigated, passive transfer via ingestion of prey, and possible bioaccumulation in different organs remains relatively unstudied. READ MORE

  5. 25. Quantification of the Performance of Algorithms for spectra Baseline Correction

    University essay from Lunds universitet/Fysiska institutionen; Lunds universitet/Beräkningsbiologi och biologisk fysik - Genomgår omorganisation

    Author : Ruijue Huang; [2023]
    Keywords : Physics and Astronomy;

    Abstract : Spectroscopy serves as a vital tool in both scientific research and industrial applications. In spectral analysis, baseline correction is important in order to be able to efficiently extract essential features. READ MORE
