  1. 1. Photo-chemical reactivity of dissolved organic carbon in subarctic lakes from northern Sweden

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Author : Hani Younes; [2020]
    Keywords : Photo-reactivity; DOM; subarctic lakes; EEM-PARAFAC. Brownification; Earth and Environmental Sciences;

    Abstract : Dissolved organic matter (DOM) is the major absorber of sunlight in most natural waters and a critical component of the carbon cycle in aquatic systems. The photochemical decomposition of DOM can have a significant impact on the landscape-atmosphere carbon exchange. READ MORE

  3. 2. Visualization and Classification of Neurological Status with Tensor Decomposition and Machine Learning

    University essay from Linköpings universitet/Institutionen för datavetenskap

    Author : Thi Pham; [2019]
    Keywords : Stress assessment; physiological signals; biosensors; tensor decomposition; feature visualization; machine learning;

    Abstract : Recognition of physical and mental responses to stress is important for stress assessment and management as its negative effects in health can be prevented or reduced. Wearable technology, mainly using electroencephalogram (EEG), provides information such as tracking fitness activity, disease detection, and monitoring neurologicalstates of individuals. READ MORE

  4. 3. Speeding up PARAFAC : Approximation of tensor rank using the Tucker core

    University essay from Uppsala universitet/Statistiska institutionen

    Author : Lukas Arnroth; [2018]
    Keywords : Tucker decomposition; PARAFAC; tensor rank; split-half analysis;

    Abstract : In this paper, the approach of utilizing the core tensor from the Tucker decomposition, in place of theuncompressed tensor, for nding a valid tensor rank for the PARAFAC decomposition is considered.Validity of the proposed method is investigated in terms of error and time consumption.

  5. 4. Dissolved organic matter (DOM) quality in agricultural streams and its impact on carbon dioxide concentrations in stream water

    University essay from Uppsala universitet/Institutionen för geovetenskaper

    Author : Karin Broqvist; [2018]
    Keywords : DOM quality; dissolved organic matter; DOC; PARAFAC; fluorescence; streams; agriculture; fluorescence index; freshness index; humification index; carbon dioxide; DOM kvalitet; löst organiskt material; DOC; PARAFAC; fluorescens; bäckar; jordbruk; fluorescence index; freshness index; humification index; koldioxid;

    Abstract : Inland waters have lately been recognized to be an important component in the carbon cycle, having a significant role in carbon sequestration and carbon dioxide (CO2) emissions. Attention has also been drawn to the impact of the quality (i.e. composition and source) of dissolved organic matter (DOM) on CO2 production. READ MORE

  6. 5. Application of 2D fluorescence spectroscopy on faecal pigments in water : characterization of wastewater fluorescence and potential indication of faecal pollution

    University essay from SLU/Dept. of Energy and Technology

    Author : Bärbel Daub; [2017]
    Keywords : wastewater; faecal pollution; faecal pigment; fluorescence; urobilin; stercobilin;

    Abstract : Drinking water pollution by faeces and associated enteric pathogens can cause serious health issues and outbreaks of diseases. A fast and reliable indication of faecal pollution is necessary to prevent the consumption of polluted water. READ MORE
