  2. 2. Virtual Sensing of Combustion Quality in SI Engines using the Ion Current

    Författare :Nicholas Wickström; Bertil Svensson; Gerard W. Malaczynski; Chalmers University of Technology; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; neural networks; spark ignition; ion current; internal combustion engines; control; estimation; Internal Combustion Engines; Spark Ignition; Estimation; Control; Neural Networks; Ion Current;

    Sammanfattning : Several virtual sensors for combustion quality in spark ignited internal combustion engines are proposed. The virtual sensors estimate combustion quality based on the ion current signal measured in the center of the combustion chamber. Important properties of these sensors are their cost effective implementation and real-time operation. LÄS MER

  3. 3. Signal processing for MEMS sensor based motion analysis system

    Författare :Jiaying Du; Maria Lindén; Nicholas Wickström; Mälardalens högskola; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; Computer Science; datavetenskap;

    Sammanfattning : Sensor systems for motion analysis represent an important class of embeddedsensor systems for health, and are usually based on MEMS technology(Micro-electro-mechanical systems). Gyroscopes and accelerometers are two examples of MEMS motion sensors that are characterized by their small size,low weight, low power consumption, and low cost. LÄS MER

  4. 4. Dynamic Visual Learning

    Författare :Joakim Johnander; Michael Felsberg; Martin Danelljan; Nicholas Wickström; Bernt Schiele; Linköpings universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Autonomous robots act in a \emph{dynamic} world where both the robots and other objects may move. The surround sensing systems of said robots therefore work with dynamic input data and need to estimate both the current state of the environment as well as its dynamics. LÄS MER

  5. 5. Gait Event Detection in the Real World

    Författare :Siddhartha Khandelwal; Nicholas Wickström; Thorsteinn Rögnvaldsson; Brian Caulfield; Högskolan i Halmstad; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; ENGINEERING AND TECHNOLOGY; gait analysis; gait event detection; wearable sensors; accelerometers;

    Sammanfattning : Healthy gait requires a balance between various neuro-physiological systems and is considered an important indicator of a subject's physical and cognitive health status. As such, health-related applications would immensely benefit by performing long-term or continuous monitoring of subjects' gait in their natural environment and everyday lives. LÄS MER
