  1. 11. Advancing the measurement of sedentary behaviour : classifying posture and physical (in-)activity

    Författare :Roman Peter Kuster; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Sedentary behaviour, defined by a sitting body posture with minimal-intensity physical activity, is an emergent public health topic. The time spent sedentary is associated with the incidence of non-communicable chronic diseases such as type 2 diabetes and cardiovascular disease and significantly shortens life-expectancy in a dose-response relationship.

  3. 12. Estimation for Sensor Fusion and Sparse Signal Processing

    Författare :Dave Zachariah; Magnus Jansson; Fredrik Gustafsson; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Estimation theory; sensor fusion; sparse signal processing;

    Sammanfattning : Progressive developments in computing and sensor technologies during the past decades have enabled the formulation of increasingly advanced problems in statistical inference and signal processing. The thesis is concerned with statistical estimation methods, and is divided into three parts with focus on two different areas: sensor fusion and sparse signal processing. LÄS MER

  4. 13. GNSS-aided INS for land vehicle positioning and navigation

    Författare :Isaac Skog; Peter Händel; Bengt Boberg; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Signal processing; Signalbehandling;

    Sammanfattning : This thesis begins with a survey of current state-of-the art in-car navigation systems. The pros and cons of the four commonly used information sources — GNSS/RF-based positioning, vehicle motion sensors, vehicle models and map information — are described. Common filters to combine the information from the various sources are discussed. LÄS MER

  5. 14. Learning Human Gait

    Författare :Parinaz Kasebzadeh; Fredrik Gustafsson; Gustaf Hendeby; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : Pedestrian navigation in body-worn devices is usually based on global navigation satellite systems (GNSS), which is a sufficient solution in most outdoor applications. Pedestrian navigation indoors is much more challenging. Further, GNSS does not provide any specific information about the gait style or how the device is carried. LÄS MER

  7. 15. Joint Positioning and Multipath Radio Channel Estimation and Prediction

    Författare :Anders Mannesson; Institutionen för reglerteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : This thesis investigates the topic of joint positioning and radio channel estimation and prediction. Both positioning and radio channel estimation have a long history of research with many publications but the combination of the two has so far at large been left unexplored. LÄS MER
