Fatigue strength assessment of riveted railway bridge details based on regression analyses combined with probabilistic models
(Peer reviewed; Journal article, 2023)With the increasing attention on structural reliability and integrity, the probabilistic fatigue behaviour of riveted joints is drawn more attention, more specifically in the influence that this may have on the fatigue ... -
Fatigue Strength Assessment of Steel Rollers: On the Reliability of the Strain Energy Density Approach on Real Components
(Journal article; Peer reviewed, 2018)Welded joints are one of the most widely applied methods to join different steel components. However, they introduce stress concentrators that are commonly known to reduce the fatigue strength of structures. Several methods ... -
Fatigue strength of blunt V-notched specimens produced by selective laser melting of Ti-6Al-4V
(Journal article, 2018)Selective Laser Melting (SLM) process is an Additive Manufacturing (AM) technique that allows producing metallic parts of any kind of geometry with densities greater than 99.5%. Complex shapes lead however to notches with ... -
Fatigue-related gait adaptations in children with cerebral palsy
(Peer reviewed; Journal article, 2023)Aim To obtain insights into the effects of fatigue on the kinematics, kinetics, and energy cost of walking (ECoW) in children with cerebral palsy (CP). Method In this prospective observational study, 12 children ... -
Fatigueless structures inspired by Nature: a case study
(Peer reviewed; Journal article, 2019)Biomimetic has begun to offer significant potential in providing unique solutions in materials science. However, the full potential of mimicking natural systems can be fully exploited only if we start to look the problem ... -
Fatty acid composition of the postlarval daubed shanny (Leptoclinus maculatus) during the polar night
(Peer reviewed; Journal article, 2020)Recent discoveries of high levels of biological activity in the Arctic marine ecosystems during the polar night raise questions regarding the ecophysiology of the pelagic postlarval daubed shanny Leptoclinus maculatus. Of ... -
Fatty Acids Composition and HIV Infection: Altered Levels of n-6 Polyunsaturated Fatty Acids Are Associated with Disease Progression
(Peer reviewed; Journal article, 2023)Fatty acids (FAs) are important regulators of immune responses and innate defense mechanisms. We hypothesized that disturbed FA metabolism could contribute to the progression of HIV infection. Plasma levels of 45 FAs were ... -
Fatty Acids Composition of the Muscles of Leptoclinus maculatus (Stichaeidae) postlarvae from Kongsfjord and Rijpfjord, Spitsbergen
(Peer reviewed; Journal article, 2022)The fatty acids composition of total lipids and individual lipid classes (phospholipids and triacylglycerols) were studied in the muscles of daubed shanny Leptoclinus maculatus postlarvae at different stages of development ... -
Fault detection and classification in oil wells and production/service lines using random forest
(Peer reviewed; Journal article, 2020)This papers deals with the automatic detection and classification of faulty events during the practical operation of oil and gas wells and lines. The events considered here are part of the publicly available 3W database ... -
Fault detection and diagnosis of a blade pitch system in a floating wind turbine based on Kalman filters and artificial neural networks
(Peer reviewed; Journal article, 2021)This paper describes the development of a fault detection and diagnosis method to automatically identify different fault conditions of a hydraulic blade pitch system in a spar-type floating wind turbine. For fault detection, ... -
Fault Detection and Prediction in Smart Grids
(Chapter, 2018)Modern society is to a larger and larger extent dependant on electric energy, and hence the reliance on and utilization of the electric grid is increasing steadily. At the same time the production and consumption patterns ... -
Fault detection in glucose control: Is it time to move beyond CGM data?
(Journal article; Peer reviewed, 2018)People with diabetes mellitus type 1 could benefit from fully automated systems for glucose control. However, faults in any component of the system can severely compromise the safety of the user. An increasing degree of ... -
Fault detection of offshore wind turbine drivetrains in different environmental conditions through optimal selection of vibration measurements
(Peer reviewed; Journal article, 2023)In this study, a vibration-based fault detection method is proposed for offshore wind turbine drivetrain based on the optimal selection of the acceleration measurements. The main aim is to find the sensor positions mounted ... -
Fault Detection with LSTM-Based Variational Autoencoder for Maritime Components
(Journal article; Peer reviewed, 2021)Maintenance routines on ships today follow either a reactive maintenance (RM) or preventive maintenance (PvM) approach. RM can be regarded as post-failure repair, which might create large costs. PvM uses predetermined ... -
Fault Detection, Localization and Clearance for MMC based on Indirect Finite Control Set Model Predictive Control
(Chapter, 2023)In this paper, indirect finite control set model predictive control (I-FCS-MPC) is used for detecting, localizing, and tolerating open-circuit failures in the transistors without the use of arm voltage sensors. The fault ... -
Fault diagnosis of downhole drilling incidents using adaptive observers and statistical change detection
