2. 1. Detection and Classification in Electrocardiac Signals

   Author : Magnus Åström; Institutionen för elektro- och informationsteknik; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Signalbehandling; Signal processing; morphology classification; QRS detection; ischemia; body position changes; electrogram; ECG; electrocardiogram; clustering; classification; Detection; sensing;

   Abstract : Signal processing can be used to condition medical signals to facilitate their interpretation, and to extract clinically important information. The purpose of the present doctoral thesis is to put forward solutions to certain problems encountered in the processing of electrocardiac signals. READ MORE

4. 2. 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

5. 3. Novel Approaches to ECG-Based Modeling and Characterization of Atrial Fibrillation

   Author : Frida Sandberg; Institutionen för elektro- och informationsteknik; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; HMM; ECG; Biomedical Signal Processing; Time-Frequency Analysis; Atrial Fibrillation; Sample Entropy; AV modeling;

   Abstract : This thesis deals with signal processing algorithms for analysis of the electrocardiogram (ECG) during atrial fibrillation (AF). Such analysis can be used for diagnosing patients, and for monitoring and predicting their response to various treatment. 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. Intelligent Driver Mental State Monitoring System Using Physiological Sensor Signals

   Author : Shaibal Barua; Peter Funk; Shahina Begum; Mobyen Uddin Ahmed; Christer Ahlström; Jose Peña; Mälardalens högskola; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Artificial Intelligent; Intelligent systems; Physiological signal; Driver monitoring; Computer Science; datavetenskap;

   Abstract : Driving a vehicle involves a series of events, which are related to and evolve with the mental state (such as sleepiness, mental load, and stress) of the driv- er. These states are also identified as causal factors of critical situations that can lead to road accidents and vehicle crashes. READ MORE
