  1. 11. Prediction of flue gas properties using artificial intelligence : Application of supervised machine learning by utilization of Near-Infrared Spectroscopy on solid biofuels

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

    Author : Bashe Abdirahman Hussein; Emran Samimi; [2022]
    Keywords : Artificial Intelligence; Machine learning; Near-Infrared spectroscopy; Solid biofuels; Fuel element; Flue gas composition; CCS;

    Abstract : This degree project studies implementation and comparison of different AI models to predict (1) solid biofuel elements including carbon, hydrogen, nitrogen, and oxygen as well as moisture content, ash content, and higher heating value (HHV) of the fuel and (2) flue gas compositions such as concentration of carbon dioxide, carbon monoxide, nitrogen, nitrogen oxides, and water content using near-infrared spectroscopy and chemometric approaches. The study executes these predictions by simulating the operation of a combined heat and power plant (CHP) that is equipped with carbon capture and storage (CCS). READ MORE

  3. 12. Nature's effect on stress in women : A systematic review

    University essay from Högskolan i Skövde/Institutionen för biovetenskap

    Author : Sofia Rang; [2022]
    Keywords : Nature; forest environment; stress; heart-rate variability; near-infrared spectroscopy;

    Abstract : This systematic review aims to evaluate which effects nature exposure has on stress in women and get a more objective viewpoint using measurements of physiological markers of stress to complement the many studies using subjective questionnaires. A search was done on Scopus, Medline EBSCO, and Web of Science for peer-reviewed, published, and original research. READ MORE

  4. 13. Prototype Instrumentation for Frequency Domain – Functional Near Infrared Spectroscopy

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

    Author : Rohit Rathnam Nareshkumar; [2022]
    Keywords : Neurofeedback; Frequency domain fNIRS; vertical-cavity surface-emitting laser; silicon photomultiplier;

    Abstract : Frequency domain functional near infrared spectroscopy (FD-fNIRS) is a tissue optical measurement technique used to measure absolute haemoglobin concentrations in brain tissue. This work is intended to be the first step in the development of a wearable, low-cost FD-fNIRS device for neurofeedback applications. READ MORE

  5. 14. Detecting Social Breathing : Quantitative signs of interaction in conversational data

    University essay from Umeå universitet/Institutionen för fysik

    Author : Cordelia Horns; [2022]
    Keywords : time series; interaction; human interaction; data analysis; wavelet analysis; machine learning; Social Breathing;

    Abstract : Human interaction has been a focus of study in psychology for a long time, but until recentlyonly very specific aspects of interaction have been considered. This approach leads to studiesthat gave insights into certain contexts, like parent-child or patient-clinician dynamics [1], [2]. READ MORE

  6. 15. Brain activity during flow : A systematic review

    University essay from Högskolan i Skövde/Institutionen för biovetenskap

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

    Abstract : 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”. READ MORE
