Active surge control of centrifugal compression systems: Theoretical and experimental results of drive actuation
(Doktoravhandlinger ved NTNU, 1503-8181; 2007:126, Doctoral thesis, 2007)
This thesis addresses modeling and active surge control of a simple compression system, using only the drive system of the compressor for actuation. Theoretical results are validated by experiments on a test rig that was ...
A Model-based Approach for Clinical Evaluation of Left Ventricular Deformation
(Doktoravhandlinger ved NTNU, 1503-8181; 2004:48, Doctoral thesis, 2004)
Assessment of left ventricular (LV) deformation is essential for clinical evaluation of LV function and cardiac images are frequently used to evaluate the LV motion and function. By combining the images with mathematical ...

(Doktoravhandlinger ved NTNU, 1503-8181; 2205:228, Doctoral thesis, 2005)
Cantor minimal systems and AF-equivalence relations
(Doktoravhandlinger ved NTNU, 1503-8181; 2008:54, Doctoral thesis, 2008)
Seismic data compression using subband coding
(Dr. ingeniøravhandling, 0809-103X; 2000:61, Doctoral thesis, 2000)
Multiscale-Streamline Inversion for High-Resolution Reservoir Models
(Doktoravhandlinger ved NTNU, 1503-8181; 2007:211, Doctoral thesis, 2007)
The topic of this thesis is streamline-based integration of dynamic data for porous media systems, particularly in petroleum reservoirs. In the petroleum industry the integration of dynamic data is usually referred to as ...
Ultrasound Guided Surgery: Image Processing and Navigation
(Dr. ingeniøravhandling, 0809-103X; 2000:84, Doctoral thesis, 2000)
The need for spectrally efficient transmission on mobile and wireless channels is prevalent. A promising scheme for such transmission is adaptive coded modulation. In this thesis, techniques for assessing the performance ...
Multivariable process control in high temperature and high pressure environment using non-intrusive multi sensor data fusion
(Doktoravhandlinger ved NTNU, 1503-8181; 2006:38, Doctoral thesis, 2006)
The main objective of this thesis is to use available knowledge about a process and combine this with measurement data from the same process to extract more information about the process. The combination of knowledge and ...
Gait Recognition Using Wearable Motion Recording Sensors
(Journal article; Peer reviewed, 2009)
This paper presents an alternative approach, where gait is collected by the sensors attached to the person's body. Such wearable sensors record motion (e.g. acceleration) of the body parts during walking. The recorded ...
Analysis and Enhancement of Random Number Generator in FPGA Based on Oscillator Rings
(Peer reviewed; Journal article, 2009)
A true random number generator (TRNG) is an important component in cryptographic systems. Designing a fast and secure TRNG in an FPGA is a challenging task. In this paper, we analyze the TRNG designed by Sunar et al. (2007) ...
