This work investigates the nucleation of droplets from supercooled CO2 and CO2-rich gas during decompression, using classical nucleation theory (CNT). We model the supercooling limit employing highly accurate equations of state and compare the result with nucleation pressures determined from...
In this paper, we investigate the time and frequency dynamics of connectedness among green assets such as green bonds, clean energy markets, and carbon prices. Using daily price data, we explore return spillovers across these green financial markets by applying the novel framework on time and...
Global investment in offshore wind energy is anticipated to surge in the coming decades. While improved technology, reduced costs, and generous policy support are frequently acknowledged as driving factors, many assert that there are fewer societal challenges with offshore renewable installations...
This study examines how melt treatment and pouring temperature affect the microstructure and mechanical properties of A356 aluminum alloy. Samples were cast under degassed, non-degassed, and upgassed conditions at 725, 750, and 775 °C. Melt quality was assessed using the reduced pressure test (RPT...
This study presents direct numerical simulation (DNS) of finite-size, interface-resolved ammonia and n-heptane droplets evaporating in decaying homogeneous isotropic turbulence. Simulations are conducted for each fuel to model the dynamics in a dense spray region, where the liquid volume fraction...
Et glasstak består av komplekse systemer med profiler, isolerruter og drenering, og krever derfor helhetlig planlegging fra tidlig prosjektfase. Glasstak kan gi flotte, lyse rom, men stiller høye krav til prosjektering. Både fukt, snø, belastninger, lyd, brann og energieffektivitet må håndteres på...
Hensikt: Undersøke potensialet rundt video som dokumentasjonsmetode innen fysioterapi for barn og ungdom, og identifisere fasilitatorer og barrierer for bruk og implementering. Design: Studien fulgte fysioterapeuter fordelt på seks samarbeidslokasjoner i privat-, kommunal- og...
Tiden er inne for et teknologi- og innovasjonsfond som kan gi Afrika gode klimaløsninger med innebygde muligheter for næringsutvikling....
With the advent of Generative AI (GenAI) and its application in various industries, research has begun showing how this new technology might impact aspects such as teamwork, perceived productivity and the nature of work tasks. However, there is still a lack of studies investigating the emotional...
Hydropower is a low-carbon energy technology with a unique capability to provide flexibility and long-term energy storage, thus being a key contributor to cost-effective and reliable decarbonisation of power systems. To ensure sustainable operation, environmental regulations are normally imposed on...
The IEC Test Report Format (TRF) standardizes product testing and compliance, ensuring consistency across international standards and simplifying global certification. However, the increasing complexity of Artificial Intelligence (AI) and Functional Safety (FuSa) and Cybersecurity demands a more...
The research presented in this paper highlights the need for updating and expanding the chapters and content of safety cases to accommodate the evolving technological and regulatory landscape, particularly with the integration of AI in safety-critical systems. We have evaluated the relevant topics...
Refrigerated liquid ammonia at atmospheric pressure is considered the safest transport and storage mode. In recent years, ammonia has gained attention as an alternative fuel to abate carbon emissions from the shipping fleet. Its implementation and use on the waterways imply some careful adjustments...
Most zeta potential data for consolidated porous samples are obtained using an in-house-built apparatus for streaming potential measurements, without an established benchmarking procedure. It is demonstrated that a commonly used method of result comparison with available literature is unreliable...
Increasing uncertainty and intermittency in the energy grid require greater flexibility. Micro-combined heat and power (micro-CHP) systems enhance flexibility by generating both heat and electricity while also supporting grid stability. However, frequent cycling and varying operational conditions...
Fish gelatins (FG) are increasingly studied and implemented as substitutes for mammalian tissue-derived gelatins in microencapsulation owing to dietary, religious and health considerations. In this study, gelatin extracted from salmon skin (including two different hydrolysates), salmon bone and cod...
The oceans will become the major contributor to the needed increase in global food production towards 2050. The fish farming industry is characterised by operations that are susceptible to changing weather, wind and currents, and face challenges when it comes to safety for fish and personnel...
Meaningful human control (MHC) of safety critical systems is a important goal as digitalization, automation/artificial intelligence (AI), and remote oversight are implemented. In the EU/AI regulation, the concept of human oversight is introduced, especially for safety critical operations. MHC and...
This paper presents an iterative algorithm for tuning of converter control loops by utilizing parametric eigenvalue sensitivities. The tuning algorithm is designed to affect the eigenvalues representing poorly damped oscillations or slow responses that significantly impact the system outputs. The...
Mono-ethylene glycol (MEG) is added to drilling fluid as an inhibitor, to prevent the formation of hydrates. While most studies of MEG as hydrate inhibitor have considered natural gas hydrates, MEG is also a natural candidate for CCS infill wells alleviating risk for CO2 hydrates. In addition to the...
