In power grid modernisation, optimal network use is essential to preserving acceptable voltage profiles, boosting voltage stability, reducing power losses, and strengthening system security and dependability. This can be accomplished by strategically placing reactive power compensation devices within transmission and distribution networks, such as capacitor banks, synchronous condensers, flexible ...

Thetransitiontonet-zeroemissionsinEuropeisdeterminedbyapatchworkofcountry-levelandEUwide policy, creating coordination challenges in an interconnected system. We use an optimisation model to mapoutnear-optimal energy system designs for 2050, focussing on the planning flexibility of individual regions while maintaining overall system robustness against different weather years, cost assumptions, and ...

Accurate segmentation of subcellular structures from microscopy images is crucial for understanding cellular processes and functions, but it presents significant challenges due to factors such as noise, low signal-to-noise ratios, limited resolution, and complex spatial arrangements. To address these challenges, we introduce CMU-Net, a novel hybrid architecture that combines the strengths of U-Net, ...

While climate change is of global concern, its impacts are especially rapid and pronounced in Arctic ecosystems. Arctic glaciers have been particularly impacted, with increasing melt and retreat in conjunction with shifts in riverine freshwater and sediment discharge. Arctic fjords are the ultimate recipients of glacial discharge and a plethora of heavy metals released from glacial environments. ...

Et mål med SUM-prosjektet (nærmere beskrevet i kapittel 5) var å legge til rette for at lærere skulle utvikle sin undervisningskompetanse innen utforskende matematikkundervisning. Forrige kapittel identifiserte noen konkrete aspekter ved organiseringen av SUM-prosjektet som ga muligheter for en slik utvikling, samt potensielle hindringer/barrierer som man også må ta hensyn til. Men i hvor stor grad ...

Uncontrolled over-fishing has been exemplified by the UN as a serious ecological challenge and a major threat to sustainable food supplies. Emerging trends within governing bodies point towards digital solutions by deploying CCTV-based video monitoring systems on a large scale. We conjecture that such systems are not feasible when reliant on satellite broadband in remote areas, and expose workers ...

In the context of Edge Computing or Cyber-Physical Systems, cross-functional, and cross-geographical DevOps teams are in charge of automating deployments, configuration, and management (i.e., reconfiguration) of complex, large-scale, highly dynamic, and geo-distributed service-oriented software systems. In this context, DevOps teams cannot reasonably manually coordinate their reconfiguration operations ...

Methane is a powerful greenhouse gas whose emission into the atmosphere from Arctic environments is increasing in response to climate change. At present, the increase in atmospheric methane concentrations recorded at Ny-Ålesund and globally threatens the Paris Agreement goal of limiting warming to 2 degrees, preferably 1.5 degrees, by increasing the need for abatements. However, our understanding ...

Planktic foraminifers are ubiquitous marine calcifiers sensitive to ocean biogeochemical and physical changes. Their fossil remains have thus been widely used for the reconstruction of past oceanographic and climatic changes. Here, we have investigated the distribution patterns of planktic foraminiferal species, their abundance, shell size, and preservation state in two sediment cores from the ...

Flere typer utstyr kan brukes for å overvåke søppel på havbunnen, inkludert droppkameraer, ROV-er (Remotely Operated Vehicles) og AUV-er (Autonomous Underwater Vehicles). Droppkamera og videorigger er kostnadseffektive og kan dekke store områder, men har begrenset fleksibilitet for nærmere undersøkelser. ROV-er gir større frihet og kan stoppe for nærmere inspeksjon, men er dyrere og vær- og ...
