  1. 1. Distance estimations by non-linear step length models using accelerometer sensor data from waist-worn smart-phones

    Master-uppsats, Lunds universitet/Matematisk statistik

    Författare :Benjamin Drorsén; Daniel Strandberg; [2018]
    Nyckelord :Mathematics and Statistics;

    Sammanfattning : This thesis examines the possibility of modelling trajectory and estimating distance during a walk using only a smart phone attached to the waist. Due to GPS not functioning indoors, a navigation system without the need of external communication could be the perfect complement for closed spaces. LÄS MER

  3. 2. Human Activity Recognition using Deep Learning and Sensor Fusion

    Master-uppsats, Lunds universitet/Matematik LTH

    Författare :Klas Berggren; [2018]
    Nyckelord :Mathematics and Statistics;

    Sammanfattning : The subject of this thesis is human activity recognition in health care. The data set used is the SBHAR data set. It contains accelerometer and gyroscope of 30 different individuals walking, walking upwards, walking downwards, sitting, standing and lying. LÄS MER

  4. 3. Attitude Navigation using a Sigma-Point Kalman Filter in an Error State Formulation

    Master-uppsats, KTH/Rymd- och plasmafysik

    Författare :Periklis-Konstantinos Diamantidis; [2017]
    Nyckelord :unscented Kalman filtering; information ltering; quaternions; attitude navigation; gyroscope modelling; error state formulation; sensor fusion;

    Sammanfattning : Kalman filtering is a well-established method for fusing sensor data in order to accuratelyestimate unknown variables. Recently, the unscented Kalman filter (UKF) has beenused due to its ability to propagate the first and second moments of the probability distribution of an estimated state through a non-linear transformation.

  5. 4. Balancing arm for a Robotic Waiter

    Kandidat-uppsats, KTH/Maskinkonstruktion (Inst.)

    Författare :JACOB EDSTRÖM; JONATHAN GUNNARSSON; [2016]
    Nyckelord :;

    Sammanfattning : This project focuses on balancing a drinking glass, to be able to transport it without the contents being spilled. It is designed with the aim of replacing a waiter in a restaurant or bar environment, but the technology itself could well be applied on mobile cup holders in cars or boats for instance. LÄS MER

  7. 5. Modelling of gyro in an IR seeker for real-time simulation

    Uppsats för yrkesexamina på grundnivå, Institutionen för systemteknik

    Författare :Thomas Nordman; [2004]
    Nyckelord :Reglerteknik; gyroscope; real-time model; modelling; seeker; HWIL; IR missile; Reglerteknik;

    Sammanfattning : The target tracking system of an IR (InfraRed) guided missile is constantly subjected to disturbances due to the linear and angular motion of the missile. To diminish these LOS (Line Of Sight) disturbances the seeker of the missile can be built from a free gyroscope mounted in a very low friction suspension. LÄS MER
