ℏ -perturbative solutions of quantum Snyder and Yang models with parameters describing spontaneous symmetry breaking
(Peer reviewed; Journal article, 2023)We introduce the perturbative ℏ-power series (ℏ - Planck constant) providing the algebraic solutions of D=4 quantum Snyder and Yang models which describe relativistic quantum space-times and Lorentz-covariant quantum phase ... -
Exploring the effects of automation malfunction on team communication and coordination in ships' engine rooms
(Peer reviewed; Journal article, 2024)Automation malfunctions within complex socio-technical systems reserve the potential to significantly affect human performance. In the context of maritime operations, varying consequences of automation malfunction on human ... -
Quantum perturbative solutions of extended Snyder and Yang models with spontaneous symmetry breaking
(Peer reviewed; Journal article, 2023)We propose ħ-expansions as perturbative solutions of quantum extended Snyder and Yang models, with ħ-independent classical zero-th order terms responsible for the spontaneous breaking D = 4 and D = 5 de Sitter symmetries. ... -
Conceptual modeling for Human Systems Integration in Manned-Unmanned Teaming
(Chapter, 2023)Future systems are becoming increasingly complex as autonomous systems work closely with human operators. Transdisciplinary development is needed to create systems functioning in dynamic Manned-Unmanned Teaming (MUM-T) ... -
Prescriptive analytics for optimal multi-use battery energy storage systems operation: State-of-the-art and research directions
(Peer reviewed; Journal article, 2023)This paper presents the state-of-the-art and latest advances in implementing multi-use practices on BESS applications to the power system grid. Representative papers on modeling and optimization methods were selected, most ... -
Developing human factors design guidelines for marine electronics — the case of S-mode
(Peer reviewed; Journal article, 2023)Human factors issues with navigation equipment have been identified as a challenge to safe and efficient maritime operations. A reason behind the issues is the lack of guidance from regulatory agencies, particularly regarding ... -
Applying systems engineering to roadmapping for digital transformation in the offshore exploration and production supply chain operations
(Peer reviewed; Journal article, 2021)This article presents the results of the third cycle of an Action Research (AR) study conducted in an offshore exploration and production (E&P) operator on the Norwegian Continental Shelf (NCS) that investigated a digital ... -
Chemical equilibrium model to investigate scaling in moving bed biofilm reactors (MBBR)
(Peer reviewed; Journal article, 2019)Moving bed biofilm reactor (MBBR) is a robust, flexible and compact technology for treatment of medium to high strength wastewater. However, while treating with high concentration of ammonium, phosphorus and metal ions, ... -
The Journey Towards Computational Materials
(Peer reviewed; Journal article, 2021)This research explores the journey towards computational materials by looking at metals, powder-based materials, composite materials and smart materials. This journey can not be explored without considering the processes ... -
A fuzzy approach to rebust Social Sustainability Assessment(ISSA)
(Journal article, 2023)Social sustainability has been increasingly recognized as a fundamental component of sustainable development in recent years. It is still challenging to measure social sustainability in comparison to other dimensions of ... -
Improving biome and climate modelling for a set of past climate conditions: evaluating bias correction using the CDF-t approach
(Journal article, 2023)Climate model simulations are inherently biased. It is a notably difficult problem when dealing with climate impact assessments and model-data integration. This is especially true when looking at derived quantities such ... -
Pollen-based reconstructions of Holocene climate trends in the eastern Mediterranean region
(Peer reviewed; Journal article, 2023)There has been considerable debate about the degree to which climate has driven societal changes in the eastern Mediterranean region, partly through reliance on a limited number of qualitative records of climate changes ... -
Modeled storm surge changes in a warmer world: the Last Interglacial
(Peer reviewed; Journal article, 2023)The Last Interglacial (LIG; ca. 125 ka) is a period of interest for climate research as it is the most recent period of the Earth's history when the boreal climate was warmer than at present. Previous research, based on ... -
Long-term responses of Icelandic Arctic foxes to changes in marine and terrestrial ecosystems
(Peer reviewed; Journal article, 2023)The long-term dynamics of predator populations may be driven by fluctuations in resource availability and reflect ecosystem changes such as those induced by climate change. The Icelandic Arctic fox (Vulpes lagopus) population ... -
