  1. 1. Joint Estimation and Calibration for Motion Sensor

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Peng Liu; [2020]
    Keywords : State space model; accelerometer array; parameter estimation; Maximum Likelihood; Expectation Maximization; Gradient Descent; ill-conditioned matrix.; tillståndsmodell; accelerometerarray; parameterskattning; maximimetoden; väntevärdesmaximering; gradientsökning; illakonditionerade matriser.;

    Abstract : In the thesis, a calibration method for positions of each accelerometer in an Inertial Sensor Array (IMU) sensor array is designed and implemented. In order to model the motion of the sensor array in the real world, we build up a state space model. Based on the model we use, the problem is to estimate the parameters within the state space model.

  3. 2. Investigation on Road Noise Transmission through Steering System

    University essay from KTH/MWL Marcus Wallenberg Laboratoriet

    Author : Yuan Xie; [2017]
    Keywords : Blocked force method; vehicle NVH test; coupled system;

    Abstract : An investigation on noise transmission through the steering gear system is focused on the area of vehicle NVH (Noise Vibration and Harshness). From previous investigations it is well known that noise transmission through the steering system sometimes has a significant influence referring to tire road noise. READ MORE

  4. 3. Combining astrometric and radial velocity data for exoplanet detection

    University essay from Lunds universitet/Institutionen för astronomi och teoretisk fysik - Genomgår omorganisation; Lunds universitet/Astronomi - Genomgår omorganisation

    Author : Viktor Holmelin; [2013]
    Keywords : Physics and Astronomy;

    Abstract : Context: The Gaia satellite will be provide astrometry with micro-arcsecond accuracy. This will allow for the determination of the orbital elements of exoplanets with measurable astrometric signature. READ MORE
