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 ... -
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 ... -
Encrypted Computation
(Dr.ingeniøravhandling, 0809-103X; 2001:67, Doctoral thesis, 2001)The ability to construct software, call it a functional ciphertext, which can be remotely executed in encrypted form as an entirely self-contained unit, has the potential for some interesting applications. One such application ... -
Motion Coordination of Mechanical Systems: Leader-Follower Synchronization of Euler-Lagrange Systems using Output Feedback Control
(Doktoravhandlinger ved NTNU, 1503-8181; 2007:60, Doctoral thesis, 2007)his thesis proposes two motion synchronization approaches to coordinate the motion of a follower to a leader within the Euler-Lagrange system framework. The information requirements from the leader are that of position and ... -
