2. 1. Nonlinear phonocardiographic Signal Processing

   Author : Christer Ahlström; Per Ask; Anders Johansson; Peter Hult; Pablo Laguna; Linköpings universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Signal analysis methods; computerized cardiac auscultation system; phonocardiographic PCG signal; mitral insufficiency MI ; time- and cost-saving; Medical engineering; Medicinsk teknik;

   Abstract : The aim of this thesis work has been to develop signal analysis methods for a computerized cardiac auscultation system, the intelligent stethoscope. In particular, the work focuses on classification and interpretation of features derived from the phonocardiographic (PCG) signal by using advanced signal processing techniques. READ MORE

4. 2. Signal Characterization of Atrial Arrhythmias using the Surface ECG

   Author : Martin Stridh; Institutionen för elektro- och informationsteknik; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Signalbehandling; Signal processing; Atrial fibrillation; Atrial arrhythmias; Frequency estimation; Time-frequency analysis; QRST cancellation; ECG;

   Abstract : This doctoral thesis is comprised of five parts which deal with different signal processing problems in ECG-based characterization of atrial arrhythmias. Such characterization requires that the ventricular activity has first been cancelled in the ECG. READ MORE

5. 3. Smartware electrodes for ECG measurements : Design, evaluation and signal processing

   Author : Linda Rattfält; Per Ask; Fredrik Björefors; Kaj Lindecrantz; Linköpings universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Abstract : The aim of this thesis work has been to study textile and screen printed smartware electrodes for electrocardiographic (ECG) measurements both in terms of their electrode properties and possibility to further improve their robustness to movement induced noise by using signal processing. Smartware electrodes for ECG measurements have previously been used in various applications but basic electrical electrode properties have not sufficiently been looked into. READ MORE

6. 4. Electromyogram Signal Enhancement and Upper-Limb Myoelectric Pattern Recognition

   Author : Sara Abbaspour; Maria Lindén; Christian Antfolk; Mälardalens högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; elektronik; Electronics;

   Abstract : Losing a limb causes difficulties in our daily life. To regain the ability to live an independent life, artificial limbs have been developed. Hand prostheses belong to a group of artificial limbs that can be controlled by the user through the activity of the remnant muscles above the amputation. READ MORE

7. 5. Proposing Combined Approaches to Remove ECG Artifacts from Surface EMG Signals

   Author : Sara Abbaspour; Maria Lindén; Urban Wiklund; Mälardalens högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Abstract : Electromyography (EMG) is a tool routinely used for a variety of applications in a very large breadth of disciplines. However, this signal is inevitably contaminated by various artifacts originated from different sources. READ MORE
