Rate-distortion optimal vector selection in frame based compression
(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 ... -
Risk, Privacy, and Security in Computer Networks
(Doktoravhandlinger ved NTNU, 1503-8181; 2006:227, Doctoral thesis, 2006)With an increasingly digitally connected society comes complexity, uncertainty, and risk. Network monitoring, incident management, and digital forensics is of increasing importance with the escalation of cybercrime and ... -
Roll-out of model based control with application to paper machines
(Dr. ingeniøravhandling, 0809-103X; 2003:31, Doctoral thesis, 2003) A mechanistic nonlinear model of the wet end of paper machine 6 (PM6) at Norske Skog Saugbrugs, Norway has been developed, and used in an MPC application. The MPC provides reduced variability in many key variables, ... -
Searching and Classifying non-textual information
(Doktoravhandlinger ved NTNU, 1503-8181; 2004:51, Doctoral thesis, 2004)This dissertation contains a set of contributions that deal with search or classification of non-textual information. Each contribution can be considered a solution to a specific problem, in an attempt to map out a common ... -
Seismic data compression using subband coding
(Dr. ingeniøravhandling, 0809-103X; 2000:61, Doctoral thesis, 2000) -
Signal analysis of out-of-hospital cardiac arrest electrocardiograms for decision support during cardiopulmonary resuscitation
(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 ... -
Sparse Signal Representation using Overlapping Frames
(Dr. ingeniøravhandling, 0809-103X; 2002:91, Doctoral thesis, 2002)Signal expansions using frames may be considered as generalizations of signal representations based on transforms and filter banks. Frames for sparse signal representations may be designed using an iterative method with ... -
Spectral theory of random operators: The energy spectrum of the quantum electron in a disordered solid
(Dr. ingeniøravhandling, 0809-103X; 1992:89, Doctoral thesis, 1992) -
Stochastic Modelling and Simulation Based Inference of Fish Population Dynamics and Spatial Variation in Disease Risk
(Dr. ingeniøravhandling, 0809-103X; 2003:22, Doctoral thesis, 2003)We present a non-Gaussian and non-linear state-space model for the population dynamics of cod along the Norwegian Skagerak coast, embedded in the framework of a Bayesian hierarchical model. The model takes into account ... -
Subgroup membership problems and public key cryptosystems
(Doktoravhandlinger ved NTNU, 1503-8181; 2004:69, Doctoral thesis, 2004)Public key encryption was first proposed by Diffie and Hellman [16], and widely popularised with the RSA cryptosystem [37]. Over the years, the security goals of public key encryption have been studied [17, 22], as have ... -
Suggested Methods for Preventing Core Saturation Instability in HVDC Transmission Systems
(Dr. ingeniøravhandling, 0809-103X; 2002:15, Doctoral thesis, 2002)In this thesis a study of the HVDC related phenomenon core saturation instability and methods to prevent this phenomenon is performed. It is reason to believe that this phenomenon caused disconnection of the Skagerrak HVDC ... -
Supporting Relationships in Digital Libraries
(Doctoral thesis, 2003)The motivation for this work is based on two recognized research issues for digital libraries. One is the need for interlinked and semantically rich information spaces where relationship information is of particular ... -

The Optimization Algorithm rFSQP with Application to Nonlinear Model Predictive Control of Grate Sintering
(Dr. ingeniøravhandling, 0809-103X; 2001:74, Doctoral thesis, 2001)This thesis contributes to the research on optimization algorithms for nonlinear programming, and to the application of such algorithms to nonlinear model predictive control. Regarding the contribution to research on ... -
Thermal fatigue in stationary aluminium contacts
(Doktoravhandlinger ved NTNU, 1503-8181; 2001:113, Doctoral thesis, 2002)The conductive area of a stationary electrical contact consists of many small contact spots. The contact spots can be described as narrow metal bridges across the interface between two conductors. Deterioration of a contact ... -
Three-Dimensional Radio Channel Modeling for Mobile Communications Systems
(Dr. ingeniøravhandling, 0809-103X; 2001:89, Doctoral thesis, 2001)The work described in this report is within the area of three-dimensional (3D) radio channel modeling for mobile communications. The focus was towards rural areas, because radio coverage of rural areas is more costly when ... -
Tilting and Relative Theories in Subcategories
(Doktoravhandlinger ved NTNU, 1503-8181; 2008:39, Doctoral thesis, 2008)We show that, over an artin algebra, the tilting functor preserves (co)tilting modules in the subcategories associated to the functor. We also give a sufficient condition for the category of modules of finite projective ... -
