  1. 21. Detecting Cardiac Pulsatility and Respiration using Multiband fMRI

    Uppsats för yrkesexamina på avancerad nivå, Umeå universitet/Institutionen för fysik

    Författare :Joakim Jonsson; [2018]
    Nyckelord :fMRI; multiband; cardiac pulsation; respiration; correlation analysis; neuroimaging;

    Sammanfattning : Purpose: Arterial stiffening poses an increased risk of cerebrovascular diseases, cognitive impairments, and even dementia as cardiac pulsations reach further into the brain causing white matter hyperintensities and microbleeds. Therefore it is of interest to obtain methods to estimate and map cardiac related pulsatility in the brain. LÄS MER

  2. 22. Remote heart rate estimation by evaluating measurements from multiple signals

    Master-uppsats, KTH/Skolan för datavetenskap och kommunikation (CSC)

    Författare :Kristoffer Uggla Lingvall; [2017]
    Nyckelord :heart rate estimation; remote heart rate; heart rate; hr; pulse; pulse detection; remote pulse; photoplethysmography; plethysmography; ppg; rppg; multiple signals; fft; ica; pca;

    Sammanfattning : Heart rate can say a lot about a person's health. While most conventional methods for heart rate measurement require contact with the subject, these are not always applicable. In this thesis, a non-invasive method for pulse detection is implemented and analyzed. LÄS MER

  3. 23. A geophysical survey (TEM; ERT) of the Punata alluvial fan, Bolivia

    Master-uppsats, Lunds universitet/Geologiska institutionen

    Författare :Joakim Mårdh; [2017]
    Nyckelord :electromagnetic; geophysics; TEM; Punata; alluvial fan; Earth and Environmental Sciences;

    Sammanfattning : The Punata alluvial fan, situated in central Bolivia (Valle Alto) between the Altiplano and the lowlands, is an important aquifer for the local rural population. Due to rapid development and population growth in the area, the demand for fresh water has increased in recent year. LÄS MER

  4. 24. Luftvägshantering prehospitalt vid hjärtstopp

    Magister-uppsats, Lunds universitet/Institutionen för hälsovetenskaper

    Författare :Marcus Anundi; Andreas Gren; [2017]
    Nyckelord :Luftvägshantering prehospitalt; hjärtstopp; överlevnad; intubation; larynxmask; Medicine and Health Sciences;

    Sammanfattning : Bakgrund: Luftvägshanteringen är en av hörnstenarna vid behandling av hjärtstopp. Resultaten i olika studier skiljer sig åt avseende vilken ventilationsmetod som är bäst vid hjärtstopp. Metod: Metoden var en kvantitativ retrospektiv longitudinell registerstudie. LÄS MER

  5. 25. Indirekt mätning av laktattröskel

    Kandidat-uppsats, Gymnastik- och idrottshögskolan, GIH/Institutionen för idrotts- och hälsovetenskap

    Författare :Alexander Hilding; Frank Olkkonen; [2016]
    Nyckelord :laktat; laktattröskel; laktattrösklar; 30MTT; indirekt mätning; direkt mätning; kardiovaskulär drift; 30 minute time trial;

    Sammanfattning : Abstract Aim The aim of this study was to determine whether 30-minute time trial (30MTT) is an accurate estimator of the lactate threshold (LT) relative to direct measures of LT and whether 30MTT is applicable for untrained individuals. Question formulations: (1) Is 30MTT an accurate method for estimation of the LT in a group with varied VO2-peak? (2) Is there a difference in the accuracy of the 30MTT between a group with low and high VO2-peak? (3) Is the method applicable for untrained individuals? Method A quantitative study was conducted consisting of 10 subjects (age=26±2. LÄS MER
