  2. 2. Efficient MIMO Detection Methods

    Author : Mirsad Čirkić; Erik G. Larsson; John Thompson; Linköpings universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : For the past decades, the demand in transferring large amounts of data rapidly and reliably has been increasing drastically. One of the more promising techniques that can provide the desired performance is multiple-input multiple-output (MIMO) technology where multiple antennas are placed at both the transmitting and receiving side of the communication link.

  3. 3. Computer-based detection of cardiac arrhythmias : methods and systems

    Author : Mats-Erik Nygårds; Linköpings universitet; []
    Keywords : Arrhythmia; monitoring; feature extraction; QRS delineation; power spectrum; ventricular fibrillation; MEDICINE; MEDICIN;

    Abstract : The aim of this study was to develop methods and systems which could improve the accuracy or arrhythmia monitoring and analysis of long-term ECGs and eliminate or reduce the need for continuous visual ECG screening. The detection of arrhythmias was based on an automatic classification of heart beats, using waveform features obtained from a basis signals representation. READ MORE

  4. 4. Conformal anomaly detection : Detecting abnormal trajectories in surveillance applications

    Author : Rikard Laxhammar; Göran Falkman; Pontus Svenson; Högskolan i Skövde; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Anomaly detection; conformal prediction; trajectory analysis; video surveillance; maritime surveillance; Technology; Teknik; Skövde Artificial Intelligence Lab SAIL ; Skövde Artificial Intelligence Lab SAIL ;

    Abstract : Human operators of modern surveillance systems are confronted with an increasing amount of trajectory data from moving objects, such as people, vehicles, vessels, and aircraft. A large majority of these trajectories reflect routine traffic and are uninteresting. READ MORE

  5. 5. Improving Community Detection Methods for Network Data Analysis

    Author : Farnaz Moradi; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Spam; Overlapping Communities; Networks; Misbehavior Detection; Seed Selection; Community Detection Algorithms; Medical Query Logs;

    Abstract : Empirical analysis of network data has been widely conducted for understanding and predicting the structure and function of real systems and identifying interesting patterns and anomalies. One of the most widely studied structural properties of networks is their community structure. READ MORE
