Controller Motifs for Homeostatic Regulation and Their Applications in Biological Systems
(PhD thesis UiS;276, Doctoral thesis, 2015-12-03)Living organisms have over billions of years evolved into highly specific and complex entities. Although the range of organisms that inhabit our planet is strikingly diverse, they are all in some extent able to protect ... -
Controls of basin margin tectonics on the Lower Cretaceous sedimentation in the Norwegian Barents Sea
(PhD thesis UiS;530, Doctoral thesis, 2020-06)Structural styles and stratigraphic patterns along North Atlantic margins display a large spectrum of complexity and variability. An extensive amount of subsurface data from the north-central and south-western Barents Sea ... -
Counterterrorism as Risk Management Strategies
(PhD thesis UiS;178, Doctoral thesis, 2012-11-26)After the terrorist attacks in the USA on 11 September 2001 (9/11), most Western countries, including Norway, implemented a multiplicity of counterterrorism measures. 9/11 seems to have lowered Western governments' ... -
Crack Arresting using Cutout Repair in Tubular Offshore Joints
(PhD thesis UiS;, Doctoral thesis, 2023)Finding efficient repair methods for cracked tubular joints in offshore structures is important, both as a permanent or temporary repair solution. The exploration of such methods and techniques includes the use of hole ... -
Cracking Behavior of Reinforced Concrete Structures Subjected to Service Load: Experimental and Numerical Investigation
