1. 1. Estimation of respiratory frequency from Heart Rate Variability

   University essay from Lunds universitet/Matematisk statistik

   Author : Daniel Ågärd; [2023]
   Keywords : time-frequency analysis; multitaper spectrogram; Optimization; signal processing; heart rate variability; Mathematics and Statistics;

   Abstract : In this master's thesis the ability to estimate the respiratory frequency from heart rate variability measurement is analyzed. The goal was to implement a solution that is easily transferable to real time. READ MORE

3. 2. Extraction of Loudspeaker- and room impulse responses under overlapping conditions

   University essay from Uppsala universitet/Signaler och system

   Author : Felix Gustafsson; [2022]
   Keywords : Signal processing; Optimization; Acoustics; Dereverberation; Sparse deconvolution; Multipath propagation;

   Abstract : A loudspeaker is often considered to be a Linear Time Invariant (LTI) system, which can be completely categorized by its impulse response. What sets loudspeakers apart from other LTI-systems is the acoustical aspect including echoes, which makes it a lot harder to take accurate noise free measurements compared to other LTI-systems such as a simple RC circuit.

4. 3. Time Synchronization of TDOA Sensors Using a Local Reference Signal

   University essay from Linköpings universitet/Kommunikationssystem

   Author : Alfred Hult; [2020]
   Keywords : TDOA; synchronization; sensor network; correlation; time-delay estimation; estimation; UAV; GPS; timing signal;

   Abstract : Synchronization of distributed time difference of arrival (TDOA) sensor networks can be performed using reference signals from GPS satellites. This method provides high accuracy, but is vulnerable to jamming, and is not reliable enough to be used in military applications. READ MORE

5. 4. Evaluation of models for process time delay estimation in a pulp bleaching plant

   University essay from Umeå universitet/Institutionen för fysik

   Author : Marcus Dahlbäck; [2020]
   Keywords : ;

   Abstract : The chemical processes used to manufacture pulp are always in development to cope with increasing environmental demands and competition. With a deeper understanding of the processes, the pulping industry can become both more profitable and effective at keeping an even and good quality of pulp, while reducing emissions. READ MORE

6. 5. AN ADAPTIVE CONTROL SYSTEM BASED ON PID, I2PD AND RLS, A SIMULATED DESIGN FOR UAVS

   University essay from Mälardalens högskola/Akademin för innovation, design och teknik

   Author : Johan Gärtner; Philip Johansson; [2017]
   Keywords : RLS; PID Controller; UAV; quadrotor; adaptive control; I2PD; simulation;

   Abstract : During this master thesis an adaptive control system for angular velocity was developed. The approach focuses on radio controlled quadrotors and thereby targets a computational efficient solution. The adaptation is divided into two steps. READ MORE
