1. 1. Gaussian processes for online system identification and control of a quadrotor

   Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/Institutionen för reglerteknik

   Författare :Sverre Knutsen; [2019]
   Nyckelord :Technology and Engineering;

   Sammanfattning : The aim of this master thesis was to develop adaptive control for a quadrotor using Gaussian process regression (GP). Online regression with GPs can provide many benefits as it is a flexible non-linear regression model that can provide uncertainty measures of the estimate. However, online GP regression may also gives rise to problems. LÄS MER

3. 2. Hilbert Transform : Mathematical Theory and Applications to Signal processing

   Master-uppsats, Linköpings universitet/Matematik och tillämpad matematik; Linköpings universitet/Tekniska fakulteten

   Författare :Måns Klingspor; [2015]
   Nyckelord :Hilbert transform; Hilbert-Huang transform; Electrocardiography; Electrocardiogram; ECG; EKG; Nonstationary processes; Hilbert spectrum; Modulation; Single-sideband modulation; QRS complex; QRS; QRS detection; SSB;

   Sammanfattning : The Hilbert transform is a widely used transform in signal processing. In this thesis we explore its use for three different applications: electrocardiography, the Hilbert-Huang transform and modulation. For electrocardiography, we examine how and why the Hilbert transform can be used for QRS complex detection. LÄS MER
