Simulation and Prediction of Countercurrent Spontaneous Imbibition at Early and Late Time Using Physics-Informed Neural Networks
(Peer reviewed; Journal article, 2023-09)The application of physics-informed neural networks (PINNs) is investigated for the first time in solving the one-dimensional countercurrent spontaneous imbibition (COUCSI) problem at both early and late time (i.e., before ... -
On the three-dimensional effects of the water entry of wedges
(Peer reviewed; Journal article, 2023-09)Three-dimensional (3D) effects on the total and spanwise slamming coefficients and the pressure reductions acting on the wedge surface during water entry are modeled in a unified manner. First, the water entry of wedges ... -
Coherent feedback leads to robust background compensation in oscillatory and non-oscillatory homeostats
(Peer reviewed; Journal article, 2023-08)When in a reaction kinetic integral controller a step perturbation is applied besides a constant background, the concentration of a controlled variable (described as A) will generally respond with decreased response ... -
Risk literacy : Foundational issues and its connection to risk science
(Peer reviewed; Journal article, 2023-09)A new research area is developing, risk literacy. The term “risk literacy” basically refers to one's ability to understand and evaluate risk, in order to support and make appropriate decisions. In this article, we discuss ... -
Autonomous Trajectory Design Considering the Limitation of Torque and Drag Forces
(Master thesis, 2023)In the oil and gas industry, designing well trajectories is an important part of drilling operations that affect well construction, completion, and production. But the current trajectory planning process works in isolation ... -
Investigation of the enantioselectivity of acetylcholinesterase and butyrylcholinesterase upon inhibition by tacrine-iminosugar heterodimers
(Peer reviewed; Journal article, 2023-09)The copper-catalysed azide-alkyne cycloaddition was applied to prepare three enantiomeric pairs of heterodimers containing a tacrine residue and a 1,4-dideoxy-1,4-imino-D-arabinitol (DAB) or 1,4-dideoxy-1,4-imino-L-arabinitol ... -
Coping with different system logics of standardization in regulatory regimes. Norwegian offshore experience
(Peer reviewed; Journal article, 2023-05)This paper addresses the role of standardization in risk governance and explores challenges when unifying different system logics and standardizations in the regulator-regulated relationships in different industrial, ... -
Integrated management of safety and security (IMSS) in the nuclear industry – Organizational culture perspective
(Peer reviewed; Journal article, 2023)The study is inspired by the change in the risk landscape caused by the development of digitalization and automation in the high-risk industry. The increasing convergence of process-safety, physical security, and cybersecurity ... -
Mimicking orchids lure bees from afar with exaggerated ultraviolet signals
(Peer reviewed; Journal article, 2023-01)Flowers have many traits to appeal to pollinators, including ultraviolet (UV) absorbing markings, which are well-known for attracting bees at close proximity (e.g., <1 m). While striking UV signals have been thought to ... -
Contributions of the Norwegian Customs to Societal Security
(Master thesis, 2023)The Norwegian Customs (NC) is the only agency that enforces safety and security regulations for goods at the Norwegian border. It does so on behalf of 19 regulators, and it collaborates closely with an additional 22 agencies. ... -
A Practical Implementation of Medical Privacy-Preserving Federated Learning Using Multi-Key Homomorphic Encryption and Flower Framework
(Peer reviewed; Journal article, 2023-10)The digitization of healthcare data has presented a pressing need to address privacy concerns within the realm of machine learning for healthcare institutions. One promising solution is federated learning, which enables ... -
5G-MEC Testbeds for V2X Applications
(Peer reviewed; Journal article, 2023-05)Fifth-generation (5G) mobile networks fulfill the demands of critical applications, such as Ultra-Reliable Low-Latency Communication (URLLC), particularly in the automotive industry. Vehicular communication requires low ... -
A classification system for characterizing the integrity and quality of evidence in risk studies
(Peer reviewed; Journal article, 2023)Risk management requires a balance between knowledge and values. Knowledge consists of justified beliefs and evidence, with evidence including data, assumptions, and models. While quality and integrity of evidence are ... -
Deconvolution approach for floating wind turbines
(Peer reviewed; Journal article, 2023-05)Green renewable energy is produced by floating offshore wind turbines (FOWT), a crucial component of the modern offshore wind energy industry. It is a safety concern to accurately evaluate excessive weights while the FOWT ... -
Design and Early Age Performance of Sustainable One-Part Geopolymers for Well Cementing
(Peer reviewed; Journal article, 2023-10)One-part geopolymers, known as “just add water” (JAW), alkali-activated formulation is presented in this work. This work reveals the design and development of short-term properties of JAW geopolymers for use in oilwell ... -
