  2. 1. Regularization for Sparseness and Smoothness : Applications in System Identification and Signal Processing

    Author : Henrik Ohlsson; Lennart Ljung; Jacob Roll; Bo Wahlberg; Linköpings universitet; []
    Keywords : Regularization; sparsity; smothness; lasso; l1; fMRI; bio-feedback; TECHNOLOGY; TEKNIKVETENSKAP;

    Abstract : In system identification, the Akaike Information Criterion (AIC) is a well known method to balance the model fit against model complexity. Regularization here acts as a price on model complexity. READ MORE

  4. 2. The influence of stress variations in wet pressing

    Author : Jörgen Gullbrand; KTH; []
    Keywords : press felts; roughness; smoothness; surface structure; uniformity;

    Abstract : Two methods for the measurement of micro-scale stressvariations of press felt surfaces were developed. The methodswere based on a thin plastic film that was coated with anopaque stress-sensitive layer (Cronapress conversion film). Thefilm was compressed between a felt and a smooth surface. READ MORE

    Abstract : Tactile perception is considered an important contributor to the overall consumer experience of a product. However, what physical properties that create the specifics of tactile perception, are still not completely understood. READ MORE

  7. 5. Enhancing the Smoothness of Streaming Video for Mobile Users over Unreliable Networks

    Author : Hussein Muzahim Aziz; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : Real time video streaming over wireless network is an increasingly important and attractive service to the mobile users. Video streaming involves a large amount of data to be transmitted in real time, while wireless channel conditions may vary from time to time. READ MORE
