This article presents a method for performing Real-Time Hybrid Model testing (ReaTHM testing) of a floating wind turbine (FWT). The advantage of this method compared to the physical modelling of the wind in an ocean basin, is that it solves the Froude-Reynolds scaling conflict, which is a key issue...

Modular multilevel converters (MMC) for high voltage direct current (HVDC) application employ hundreds of sub-modules. Explicit modeling of sub-modules implies hundreds of nodes and semiconductor devices in the equivalent models for the system; this in turn poses a computational challenge for...

High-utility sequential pattern mining (HUSPM) is a hot research topic in recent decades since it combines both sequential and utility properties to reveal more information and knowledge rather than the traditional frequent itemset mining or sequential pattern mining. Several works of HUSPM have...

To reach the global aspiration of 17 ambitious SDGs, local realities must be integrated. Often, models are developed based on quantitative statistical data sources from databases on environmental indicators or economics to assess how a given SDG can be achieved. This process however removes the...

In light of climate change, the shipping industry is committed to reducing its greenhouse gas emissions. When transitioning from fossil fuels to low-carbon fuels, it is crucial to also reduce the ships' energy need. For cruise ships, the hotel system is a major energy consumer and the focus of this...

A low-power infrared source based on a silicon photonic-crystal membrane has been designed. Temperature distribution and reflection spectrum has been simulated. Large narrowband IR absorption is obtained with optimal material doping...

At present, recycled aluminium is "diluted" by primary metal to keep the impurity concentrations at acceptable levels. Future increase in recycling will require a new process for efficient removal of all impurities, including noble elements, from secondary aluminium. In the current preliminary...

The marine food web is considered to be a factor of key importance for the global carbon balance. The concept of the ‘Biological Pump’ refers to the mechanism by which CO₂ fixed by photosynthesis is transferred to the deep ocean through biologically-driven processes, resulting in sequestration of...

Dust, or airborne particulate matter, from metal smelting can be either mechanically or thermally generated and it negatively affects the indoor air quality as well as the fugitive emissions from the plant. The thermally generated dust is often referred to as fume and it is typically generated...

Large-scale storage of CO₂ in saline aquifers is considered an essential technology to mitigate CO₂ emissions. Storage potential has mainly been estimated based on volumetrics or detailed simulations for specific injection scenarios. In practice, achievable storage capacity will depend on...

Use of DREAM (Dose-related Risk and Effects Assessment Model) for modelling of discharges to the marine environment is embraced by Norwegian authorities, and it is in routine use on the Norwegian Continental Shelf (NCS), as required by regulators. The DREAM model has been developed by SINTEF with...

Noise is a major challenge in the petroleum industry. Prior to performing work in a noisy area, the noise map is the tool for assessing noise exposure when planning and performing work. The aim of this paper is to present an ongoing R&D project to develop a wireless noise monitoring system that...
