This paper proposes and investigates a reconfigurable intelligent surface (RIS) enabled bidirectional non-orthogonal multiple access (NOMA) network termed as NOMA-RIS. Here, RIS allows multiple NOMA users in one group to communicate with or share information with multiple NOMA users in another group...
Analysing spectra from experimental characterization of materials is time consuming, susceptible to distortions in data, requires specific domain knowledge, and may be susceptible to biases in general heuristics under human analysis. Recent work has shown the potential of using neural networks to...
Datafication processes, the ongoing strive for making organizations data-driven, have in recent years entailed data-focused software projects and more interdisciplinary teamwork. Simultaneously as agile product teams have been directed towards increased use of data for software development, stronger...
Stacking of solid oxide cells (SOC) requires that a robust and durable electrical contact is established between the cell and the interconnect. In this work, we present a contact layer solution for the SOC air side based on the concept of reactive oxidative bonding in which metallic Mn-Co and Mn-Cu...
Carbon capture and storage (CCS) is one of the most viable solutions to limit the CO2 emission in the atmosphere, with the potential to be applied at short-medium time scales. In this concern, polymeric materials play a relevant role in protecting equipment in the CO2 transport value chain (such as...
Målet med prosjektet er å gjøre fakta om bærekraft i norsk havbruk lett tilgjengelig. Temaer og indikatorer for både miljømessig-, økonomisk og samfunnsmessig bærekraft er nødvendige. Det er også vesentlig hvordan næringens bærekraft utvikler seg over tid. Indikatorer for både positive og negative...
Membrane technology has attracted great industrial interest in carbon capture and separation owing to the merits of energy-efficiency, environmental friendliness and low capital investment. Conventional polymeric membranes for CO2 separation suffer from the trade-off between permeability and...
In this work, a digital twin with standalone, descriptive, and predictive capabilities is created for an existing onshore wind farm located in complex terrain. A standalone digital twin is implemented with a virtual-reality-enabled 3D interface using openly available data on the turbines and their...
Low-income communities face a causality dilemma: A lack of energy services hampers income growth and insufficient income hampers energy service provision. Interventions delivering cost-effective energy services can address this dilemma, triggering a virtuous cycle of economic upliftment. While...
Når en sammenligner den levendeleverte hysa med tradisjonelt levert hyse på slakte/leveringsdagen, så er det store forskjeller med hensyn på kvalitet. Den levendeleverte hysa som blir pre-rigor prosessert har veldig lite spalting, god konsistens og lite blod i filetene, dette i motsetning til den...
Self-disclosure in human–chatbot relationship (HCR) formation has attracted substantial interest. According to social penetration theory, self-disclosure varies in breadth and depth and is influenced by perceived rewards and costs. While previous research has addressed self-disclosure in the context...
Rising shares of variable wind and solar generation in decarbonized electricity systems motivate the development of novel power cycles employing unconventional fuels. Innovative designs must be highly flexible and profitable at low capacity factors, requiring a simple process layout and low capital...
Ductile cast iron, also known as nodular cast iron, is a graphite-rich cast iron with high impact and fatigue resistance, due to its nodular graphite inclusions. Ductile cast iron is produced by incorporating additives (often FeSi alloys) to the iron base metal at different production steps to...
Microstructure and tensile properties of a hot work tool steel manufactured via laser powder bed fusion (LPBF) were investigated. Specimens were built under two different orientations and subjected to two quenching and tempering heat treatments, featuring different austenitizing and tempering...
