(Dr. ingeniøravhandling, 0809-103X; 1996:62, Doctoral thesis, 1996)A method for designing workflow systems which satisfy performance requirements is proposed in this thesis. Integration of human and computerised performance is particularly useful for workflow systems where human and ... -
Peaking Capacity in Restructured Power Systems
(Dr. ingeniøravhandling, 0809-103X; 2000:100, Doctoral thesis, 2000)The theme of this thesis is the supply of capacity during peak demand in restructured power systems. There are a number of reasons why there is uncertainty about whether an enegyonly electricity market (where generators ... -
Optimal Bit and Power Constrained Filter Banks
(Dr. ingeniøravhandling, 0809-103X; 2000:7, Doctoral thesis, 2000)In this dissertation, two filter banks optimization problems are studied. The first problem is the optimization of filter banks used in a subband coder under a bit constraint. In the second problem, a multiple input multiple ... -
Discernibility and Rough Sets in Medicine: Tools and Applications
(Dr. ingeniøravhandling, 0809-103X; 1999:133, Doctoral thesis, 2000)This thesis examines how discernibility-based methods can be equipped to posses several qualities that are needed for analyzing tabular medical data, and how these models can be evaluated according to current standard ... -
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 ... -

Frame based signal representation and compression
(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 ... -
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 ... -
Perforated Panel Absorbers with Viscous Energy Dissipation Enhanced by Orifice Design
(Dr. ingeniøravhandling, 0809-103X; 2000:67, Doctoral thesis, 2000)Currently, there is a great interest in panel absorber design where porous components are excluded due to environmental and cleaning considerations. For such absorbers, the challenge is to increase the natural, viscous ... -
