Dette dokumentet beskriver et innspill til en veileder for hygienisk design og renhold for brønnbåt. Dokumentet er strukturert og har innhold slik vi tenker at en veileder kan være. Forslaget er delt opp i en del for hygienisk design og en for renhold. Hver av disse har en generell del og en del...

Forslaget er delt opp i en del for hygienisk design og en for renhold. Hver av disse har en generell del og en del...

The method for calculating greenhouse gas (GHG) emissions in zero emission neighbourhoods (ZEN) requires clarification on a set of methodological aspects. This is due to differing approaches in established methods, such as EN 15978, NS 3720, and FutureBuilt ZERO, as well as methodological...

The foundation for a passivity-based screening method is introduced with the objective of narrowing the scope of interaction studies for converter interoperability assessment to only those locations where stability issues may arise. With the growing prevalence of renewable energy sources and...

This paper demonstrates how the internal virtual impedance in virtual synchronous machines (VSM) can be chosen to ensure stability and robustness against grid impedance variations. Three VSM implementations are considered: a current controlled VSM with dynamic electrical model (CC DEM) VSM, a...

The privacy of personal data is paramount in the realm of assisted living and digital healthcare. Federated Learning (FL), with its decentralised model training approach, has emerged as a compelling solution to reconcile the need for personalised models with the requirement to protect sensitive...

The proliferation of machine learning (ML) has brought unprecedented advancements in technology, but it has also raised concerns about its environmental impact, particularly concerning carbon emissions. To address the imperative of environmentally responsible ML, we present in this paper a novel ML...

Federated Learning (FL) has emerged as a decentralised machine learning paradigm for distributed systems, particularly in edge and IoT environments. However, ensuring fault tolerance and self-recovery in such scenarios remains challenging, because of the centralised model aggregation which acts as a...

Energy communities based on joint investments of energy assets might enable the democratisation of the power system by enabling all individuals to become active participants. Adopting this investment strategy requires ensuring fair economic value distribution among investors. Some studies propose...

Internasjonalt eksisterer det flere typer prøvingsmetoder for laboratorieprøving av ulike betongers motstand mot kloridinntrenging. I Norge har det på 90-tallet vært vanlig å bruke følgende tre metoder, Kloridmigrasjon (NT Build 355), Neddykket kloridinntrenging (APM 302 / NT Build 443; tidligere...

Security testing low-level connected devices such as Internet of Things (IoT) devices is difficult due to their limited memory, communication bandwidth, and processing power. As a result, traditional testing processes become difficult and time-consuming in such cases. In this paper, we survey...

Jammertest 2022 was a week-long series of satellite navigation and timing signal jamming and spoofing exercises carried out on the Norwegian island of Andøya in September of 2022. Organized via a collaboration between the Norwegian spectrum management authority, defense research establishment...
