  1. 16. Signal Reconstruction Algorithms for Time-Interleaved ADCs

    Författare :Anu Kalidas Muralidharan Pillai; Håkan Johansson; Christian Vogel; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : An analog-to-digital converter (ADC) is a key component in many electronic systems. It is used to convert analog signals to the equivalent digital form. LÄS MER

  3. 17. Eye-movement controlled image coding

    Författare :Peter Bergström; Andrew Duchowski; Linköpings universitet; []
    Nyckelord :;

    Sammanfattning : This thesis proposes eye-movement controlled image coding schemes. An application is found in interactive systems where a human operator controls a vehicle at a distance. Such a system would include an eye-tracker to pick up the point of regard of the viewer. LÄS MER

  4. 18. Efficient Compression and Rasterization Algorithms for Graphics Hardware

    Författare :Jon Hasselgren; Institutionen för datavetenskap; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Despite rapid development, modern graphics hardware is still much too slow to render photo-realistic images in real time, and it will most likely remain so if we rely only on yearly growth in hardware performance. Therefore, better algorithms are constantly needed in order to advance the field. LÄS MER

  5. 19. Essays on Model Assisted Survey Planning

    Författare :Anders Holmberg; Bengt Rosén; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Statistics; Statistik; Statistics; Statistik; Statistics; statistik;

    Sammanfattning : The quality of sample survey results is to a large degree dependent on decisions made by survey statisticians at the planning stage. The first paper studies two issues related to the planning stage: (i) the sensitivity of model assumptions concerning the relation between the size measure and a study variable in without replacement probability proportional-to-size sampling (πps sampling), and (ii) properties of practicable sample selection schemes for fixed size πps sampling.

  7. 20. Methods for Frequency Domain Estimation of Continuous-Time Models

    Författare :Jonas Gillberg; Lennart Ljung; Fredrik Gustafsson; Linköpings universitet; []
    Nyckelord :TECHNOLOGY; TEKNIKVETENSKAP;

    Sammanfattning : Approaching parameter estimation from the discrete-time domain is the dominating paradigm in system identification. Identification of continuous-time models on the other hand is motivated by the fact that modelling of physical systems often take place in continuous-time. LÄS MER
