    • Frame based signal representation and compression 

      Engan, Kjersti (Dr. ingeniøravhandling, 0809-103X; 2000:65, Doctoral thesis, 2000)
      The demand for efficient communication and data storage is continuously increasing and signal representation and compression are important factors in digital communication and storage systems. This work deals with Frame ...

    • Kalman smoothing for objective and automatic preprocessing of glucose data 

      Staal, Odd Martin; Sælid, Steinar; Fougner, Anders Lyngvi; Stavdahl, Øyvind (Journal article; Peer reviewed, 2018)
      A method for preprocessing a time series of glucose measurements based on Kalman smoothing is presented. Given a glucose data time series that may be irregularly sampled, the method outputs an interpolated time series of ...

    • Rate-distortion optimal vector selection in frame based compression 

      Ryen, Tom (Doktoravhandlinger ved NTNU, 1503-8181; 2005:107, Doctoral thesis, 2005)
      In signal compression we distinguish between lossless and lossy compression. In lossless compression, the encoded signal is more bit efficient than the original signal and is exactly the same as the original one when ...

    • Removal of Cardiopulmonary Resuscitation Artifacts in the Human Electrocardiogram 

      Eilevstjønn, Joar (Doktoravhandlinger ved NTNU, 1503-8181; 2004:91, Doctoral thesis, 2004)
      Death from heart diseases is the most common type of mortality in western countries and the survival rate of cardiac arrest is dismally low. In the treatment of cardiac arrest, two therapeutic methods are most important: ...

    • Shortest path methods in representation and compression of signals and image contours 

      Nygaard, Ranveig (Dr. ingeniøravhandling, 0809-103X; 2000:64, Doctoral thesis, 2000)
      Signal compression is an important problem encountered in many applications. Various techniques have been proposed over the years for adressing the problem. The focus of the dissertation is on signal representation and ...

    • Signal analysis of out-of-hospital cardiac arrest electrocardiograms for decision support during cardiopulmonary resuscitation 

      Eftestøl, Trygve C. (Dr. ingeniøravhandling, 0809-103X; 2000:66, Doctoral thesis, 2000)
      This thesis focuses on signal analysis of electrocardiograms (ECG) from out-of-hospital cardiac arrested patients. The application of such methods may eventually contribute in guiding therapy towards improved survival rates ...
