1. 11. Structural and Functional Brain Changes due to Pregnancy and Early Postpartum Period: A Systematic Review

   Kandidat-uppsats, Högskolan i Skövde/Institutionen för biovetenskap

   Författare :Sanne Lövgren; [2022]
   Nyckelord :pregnancy; brain; structural; functional;

   Sammanfattning : A big part of the female population experience pregnancy and giving birth. Evidence from animal studies indicates numerous adaptations in the brain throughout pregnancy and the postpartum period. The effects on the human brain are not as well studied, which is problematic due to the complexity of comparing species. LÄS MER

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

   Uppsats för yrkesexamina på avancerad nivå, Mälardalens universitet/Akademin för ekonomi, samhälle och teknik

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

   Sammanfattning : 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). LÄS MER

4. 13. Nature's effect on stress in women : A systematic review

   Kandidat-uppsats, Högskolan i Skövde/Institutionen för biovetenskap

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

   Sammanfattning : 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. LÄS MER

5. 14. Prototype Instrumentation for Frequency Domain – Functional Near Infrared Spectroscopy

   Master-uppsats, KTH/Skolan för kemi, bioteknologi och hälsa (CBH)

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

   Sammanfattning : 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. LÄS MER

7. 15. Detecting Social Breathing : Quantitative signs of interaction in conversational data

   Master-uppsats, Umeå universitet/Institutionen för fysik

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

   Sammanfattning : 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]. LÄS MER
