A Voltage Instability Predictor Using Local Area Measurements
(Dr. ingeniøravhandling, 0809-103X; 2002:21, Doctoral thesis, 2002)There has been a pressure to operate power systems closer to their security limits. This has partially been due to financial imperatives following the deregulating of markets. Other practical difficulties have been obtaining ... -
Acceleration Feedback in Dynamic Positioning
(Dr. ingeniøravhandling, 0809-103X; 2003:74, Doctoral thesis, 2003)This dissertation contains new results on the design of dynamic positioning (DP) systems for marine surface vessels. A positioned ship is continuously exposed to environmental disturbances, and the objective of the DP ... -
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 ... -
An Approach to Developing Extensible Application Composition Environments for End Users
(Doctoral Theses at NTNU, 1503-8181; 2006:58, Doctoral thesis, 2006)Most software is now developed by professional programmers, and the millions of users of “shrink-wrapped” applications never meet the developers. The skills of professional programmers are obviously required in many software ... -
An experimental study of Hydrodynamic Forces on Cylinders and Cables in Near Axial Flow
(Doktoravhandlinger ved NTNU, 1503-8181; 2004:125, Doctoral thesis, 2004)The thesis addresses the hydrodynamic forces on cylinders where the angle between incoming flow and the cylinder axis, the angle of attack, is low. Measured results for a rigid cylinder with length to diameter ratio of ... -
Augmenting Bioinformatics Research with Biomedical Ontologies
(Doktoravhandlinger ved NTNU, 1503-8181; 2008:78, Doctoral thesis, 2008)The main objective of the reported study was to investigate how biomedical ontologies, logically structured representations of various aspects of the biomedical reality, can help researchers in analyzing experimental data. ... -
CAGISTrans: Adaptable Transactional Support for Cooperative Work
(Dr. ingeniøravhandling, 0809-103X; 2001:94, Doctoral thesis, 2001)The theme of this thesis is on transactional support for cooperative work environments, focusing on data sharing. It is thus concerned with the provision of suitable mechanisms to manage concurrent access to shared data ... -
