1. 21. Human motion prediction using wearable sensors and machine Learning

   Författare :Binbin Su; Elena M. Gutierrez-Farewik; Christian Smith; Neil Cronin; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; wearable sensors; gait segmentation; lower limb angular velocity; machine learning; deep learning; reinforcement learning; Engineering Mechanics; Teknisk mekanik;

   Sammanfattning : Accurately measuring and predicting human movement is important in many contexts, such as in rehabilitation and the design of assistive devices. Thanks to the development and availability of a wide variety of sensors, scientists study human movement in many settings and capture characteristic properties unique to individuals as well as to larger study populations.

3. 22. Virtual reality based kinematics for assessment of post-stroke upper limb function

   Författare :Netha Hussain; Göteborgs universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; stroke; motion analysis; upper extremity; arm function; kinematics; virtual reality; outcome assessment; rehabilitation; recovery of function; task performance and analysis;

   Sammanfattning : The main scope of this thesis was to develop a method for assessing the upper limb sensorimotor function following stroke using virtual reality-based technique. The studies reported in this thesis included 67 individuals extracted from the SALGOT (Stroke Arm Longitudinal Study at the University of Gothenburg) cohort and 43 healthy controls. LÄS MER

4. 23. Analyses and Application of Ambient Seismic Noise in Sweden : Source, Interferometry, Tomography

   Författare :Hamzeh Sadeghisorkhani; Ólafur Gudmundsson; Ari Tryggvason; Roland Roberts; Frederik Tilmann; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Seismic interferometry; Ambient noise; Surface wave; Wave propagation; Inverse theory; Sweden; Geofysik med inriktning mot seismologi; Geophysics with specialization in Seismology;

   Sammanfattning : Ambient seismic noise from generation to its application for determination of sub-surface velocity structures is analyzed using continuous data recordings from the Swedish National Seismic Network (SNSN). The fundamental aim of the thesis is to investigate the applicability of precise velocity measurements from ambient noise data. LÄS MER

5. 24. Between the Probe and the Pump : An experimental study on cardiac performance analysis based on Echocardiography, tissue and laser Doppler

   Författare :Laila Hübbert; Birgitta Janerot-Sjöberg; Ulf Dahlström; Sven-Erik Ricksten; Linköpings universitet; []
   Nyckelord :MEDICINE; MEDICIN;

   Sammanfattning : Echocardiography is an ultrasound-based bedside, non-invasive and easily available cardiac diagnostic technique visualising the heart’s morphology and function. Quantification of cardiac wall motion can be measured with the tissue Doppler Imaging (TDI) modality which provides in humans a high diagnostic capacity to differentiate healthy from diseased myocardium with reduced function.

7. 25. Role of cerebral Blood Flow in Fetal Surveillance

   Författare :Riffat Cheema; Urogynekologi och reproduktionsfarmakologi; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

   Sammanfattning : ABSTRACT In high-risk pregnancies the chronic hypoxemic fetus redistributes its circulation to maintain the blood supply to the vital organs: brain, heart and adrenals. The aims of the studies included in this thesis were: 1) to establish reference curves for fetal cerebral venous blood velocity in normal pregnancies; 2) to determine in high-risk pregnancies the frequency of abnormal Doppler in the cerebral veins and uterine, umbilical and middle cerebral arteries and the umbilical vein and ductus venosus with correlation with adverse perinatal outcome; 3) to analyze the correlation between brain sparing and redistribution of circulation and placental vascular impedance; 4) to evaluate the correlation between brain sparing and fetal umbilical cord blood gases at birth.
