Hybrid Modelling and Control of Obstacle-Aided Snake Robot Locomotion
(Journal article; Peer reviewed, 2010)A snake can traverse cluttered and irregular environments by using irregularities around its body as push points to aid the propulsion. This characteristic feature of biological snake locomotion, which is denoted as ... -
Hybrid Modelling for Dynamic Reliability Assessments in Subsea Oil and Gas Processing Systems
(Master thesis, 2017)Traditional reliability methods such as fault tree analysis and reliability block diagrams were not designed to account for the complex dynamic behavior of most industrial systems. These traditional reliability methods ... -
Hybrid modelling for mooring system monitoring - A digital twin framework for floating wind turbines
(Master thesis, 2022)Flytende havvind har potensiale til å være en viktig bidragsyter mot verdens behov for fornybar energi. Vedlikeholds og installasjons kostnader må reduseres for at teknologien skal bli et konkurransedyktig alternativ til ... -
A hybrid multi-stage methodology for remaining useful life prediction of control system: Subsea Christmas tree as a case study
(Peer reviewed; Journal article, 2023)With the improvement of control system composition and operation process complexity, the uncertainty in its operation process increases and real-time observation data is difficult to obtain, and the influence of noise also ... -
Hybrid multimodal contrast agent for multiscale: In vivo investigation of neuroinflammation
(Peer reviewed; Journal article, 2021)Neuroinflammation is a process common to several brain pathologies. Despites its medical relevance, it still remains poorly understood; there is therefore a need to develop new in vivo preclinical imaging strategies to ... -
Hybrid Nanocomposites for High Voltage Insulation
(Master thesis, 2019)Bruken av nanopartikler som fyllmateriale i organiske polymerer har vist seg å forbedre ønskede egenskaper i polymerer for høyspenningsinsolasjon. Det eksisterer mange ulike metoder for forberedelse av hybride nanokompositter ... -
Hybrid Observer Combining Measurements of Different Fidelities
(Journal article; Peer reviewed, 2016)A signal-based hybrid observer combining measurements of different fidelities is proposed for position and velocity estimation of marine vessels. The concept assumes that noisy position measurements are available only ... -
Hybrid observer concept for sensor fusion of sporadic measurements for underwater navigation
(Peer reviewed; Journal article, 2020)Accurate underwater navigation systems are required for closed-loop guidance and control of unmanned underwater vehicles (UUV). This paper proposes a sensor-based hybrid translational observer concept for underwater ... -
Hybrid observer for improved transient performance of a marine vessel in dynamic positioning
(Journal article; Peer reviewed, 2016)Dynamic positioning (DP) systems are used on marine vessels for automatic station keeping and tracking operations solely by use of thrusters. Observers are key components of DP systems, and two main types are proposed in ... -
